    Countries with large stock of fissile material and producing large quantity of nuclear pure {sup 235}U and {sup 239}Pu are able to allocate part of the stock to non military research. For countries with low stock of fissile material, all the stock is allocated to military research. An economical and technical solution has to be find to dedicate a part of fissile material to non military research and develop the atomic energy industry. It stated the industrial and economical problems and in particular the choice between the use of enriched fuel with high refining cost or depleted fuel with low production cost. It discusses of four possible utilizations of the natural resources: reactors functioning with pure fissile material ({sup 235}U or {sup 239}Pu) or concentrated material ({sup 235}U mixed with small quantities of {sup 238}U after an incomplete isotopic separation), breeder reactors functioning with enriched material mixed with {sup 238}U or Thorium placed in an appropriate spatial distribution to allow neutrons beam to activate {sup 238}U or Thorium with the regeneration of fissile material in {sup 239}Pu, reactors using natural uranium or low enriched uranium can also produce Plutonium with less efficiency than breeder reactors and the last solution being the use of natural uranium with the only scope of energy production and no production of secondary fissile material. The first class using pure fissile material has a low energy efficiency and is used only by large fissile material stock countries to accumulate energy in small size fuel for nuclear engines researches for submarines and warships. The advantage of the second class of reactors, breeder reactors, is that they produce energy and plutonium. Two type of breeder reactor are considered: breeder reactor using pure fissile material and {sup 238}U or breeder reactor using the promising mixture of pure fissile material and Thorium. Different projects are in phase of development in United States, England

    This pamphlet traces the history of the US Atomic Energy Commission's twenty-eight year stewardship of the Nation's nuclear energy program, from the signing of the Atomic Energy Act on August 1, 1946 to the signing of the Energy Reorganization Act on October 11, 1974. The Commission's early concentration on the military atom produced sophisticated nuclear weapons for the Nation's defense and made possible the creation of a fleet of nuclear submarines and surface ships. Extensive research in the nuclear sciences resulted in the widespread application of nuclear technology for scientific, medical and industrial purposes, while the passage of the Atomic Energy Act of 1954 made possible the development of a nuclear industry, and enabled the United States to share the new technology with other nations.

    This self-contained text introduces readers to the field of high-energy atomic physics - a new regime of photon-atom interactions in which the photon energies significantly exceed the atomic or molecular binding energies, and which opened up with the recent advent of new synchrotron sources. From a theoretical point of view, a small-parameter characteristic of the bound system emerged, making it possible to perform analytic perturbative calculations that can in turn serve as benchmarks for more powerful numerical computations. The first part of the book introduces readers to the foundations of this new regime and its theoretical treatment. In particular, the validity of the small-parameter perturbation expansion and of the lowest-order approximation is critically reviewed. The following chapters then apply these insights to various atomic processes, such as photoionization as a many-body problem, dominant mechanisms for the production of ions at higher energies, Compton scattering and ionization accompanied b...

This Policy Pathway, jointly produced by the International Energy Agency and the Institute for Industrial Productivity, develops the critical steps for policy makers implementing energy management programmes for industry. Optimising energy use in industry is essential to improve industrial competitiveness and achieve wider societal goals such as energy security, economic recovery and development, climate change mitigation and environmental protection. While there is significant potential to decrease energy consumption in this sector, opportunities to improve energy efficiency are still under-exploited. Energy management programmes have shown to be instrumental in addressing many of the barriers that inhibit wide-scale uptake of energy management in industry. The Policy Pathway builds on lessons learned from country experiences and provides actionable guidance on how to plan and design, implement, evaluate and monitor energy management programmes for industry.

The energy bandwidth illustrates the total energy-saving opportunity that exists in the industry if the current processes are improved by implementing more energy-efficient practices and by using advanced technologies. This bandwidth analysis report was conducted to assist the ITP Mining R&D program in identifying energy-saving opportunities in coal, metals, and mineral mining. These opportunities were analyzed in key mining processes of blasting, dewatering, drilling, digging, ventilation, materials handling, crushing, grinding, and separations.

  15. The Future of Atomic Energy

    Science.gov (United States)

    Fermi, E.

    1946-05-27

    There is definitely a technical possibility that atomic power may gradually develop into one of the principal sources of useful power. If this expectation will prove correct, great advantages can be expected to come from the fact that the weight of the fuel is almost negligible. This feature may be particularly valuable for making power available to regions of difficult access and far from deposits of coal. It also may prove a great asset in mobile power units for example in a power plant for ship propulsion. On the negative side there are some technical limitations to be applicability of atomic power of which perhaps the most serious is the impossibility of constructing light power units; also there will be some peculiar difficulties in operating atomic plants, as for example the necessity of handling highly radioactive substances which will necessitate, at least for some considerable period, the use of specially skilled personnel for the operation. But the chief obstacle in the way of developing atomic power will be the difficulty of organizing a large scale industrial development in an internationally safe way. This presents actually problems much more difficult to solve than any of the technical developments that are necessary, It will require an unusual amount of statesmanship to balance properly the necessity of allaying the international suspicion that arises from withholding technical secrets against the obvious danger of dumping the details of the procedures for an extremely dangerous new method of warfare on a world that may not yet be prepared to renounce war. Furthermore, the proper balance should be found in the relatively short time that will elapse before the 'secrets' will naturally become open knowledge by rediscovery on part of the scientists and engineers of other countries.

    Full Text Available The Smart Grid vision imposes a new approach towards energy supply that is more affordable, reliable and sustainable. The core of this new vision is the use of advanced technology to monitor power system dynamics in real time and identify system in stability. In order to implement strategic vision for energy management, it is possible to identify three main areas of investigation such as smart generation, smart grid and smart customer. Focusing on the latter topic, in this paper we present an application specifically designed to monitor an industrial site with particular attention to power consumption. This solution is a real time analysis tool, able to produce useful results to have a strategic approach in the energy market and to provide statistic analysis useful for the future choices of the industrial company. The application is based on a three layers architecture. The technological layer uses a Wireless Sensor Network (WSN to acquire data from the electrical substations. The middleware layer faces the integration problems by processing the raw data. The application layer manages the data acquired from the sensors. This WSN based architecture represents an interesting example of a low cost and non-invasive monitoring application to keep the energy consumption of an industrial site under control. Some of the added value features of the proposed solution are the routing network protocol, selected in order to have an high availability of the WSN, and the use of the WhereX middleware, able to easily implement integration among the different architectural parts.

    This paper presents an overview of the modeling approach andhighlights key findings of a California industrial energy efficiencypotential study. In addition to providing estimates of technical andeconomic potential, the study examines achievable program potential undervarious program-funding scenarios. The focus is on electricity andnatural gas savings for manufacturing in the service territories ofCalifornia's investor-owned utilities (IOUs). The assessment is conductedby industry type and by end use. Both crosscutting technologies andindustry-specific process measures are examined. Measure penetration intothe marketplace is modeled as a function of customer awareness, measurecost effectiveness, and perceived market barriers. Data for the studycomes from a variety of sources, including: utility billing records, theEnergy Information Association (EIA) Manufacturing Energy ConsumptionSurvey (MECS), state-sponsored avoided cost studies, energy efficiencyprogram filings, and technology savings and cost data developed throughLawrence Berkeley National Laboratory (LBNL). The study identifies 1,706GWh and 47 Mth (million therms) per year of achievable potential over thenext twelve years under recent levels of program expenditures, accountingfor 5.2 percent of industrial electricity consumption and 1.3 percent ofindustrial natural gas consumption. These estimates grow to 2,748 GWh and192 Mth per year if all cost-effective and achievable opportunities arepursued. Key industrial electricity end uses, in terms of energy savingspotential, include compressed air and pumping systems that combine toaccount for about half of the total achievable potential estimates. Fornatural gas, savings are concentrated in the boiler and process heatingend uses, accounting for over 99 percent to total achievablepotential.

    2016-10-01

    Full Text Available Organic coatings have been widely used in atomic physics during the last 50 years because of their mechanical properties, allowing preservation of atomic spins after collisions. Nevertheless, this did not produce detailed insight into the characteristics of the coatings and their dynamical interaction with atomic vapors. This has changed since the 1990s, when their adsorption and desorption properties triggered a renewed interest in organic coatings. In particular, a novel class of phenomena produced by non-destructive light-induced desorption of atoms embedded in the coating surface was observed and later applied in different fields. Nowadays, low energy non-resonant atomic photodesorption from organic coatings can be considered an almost standard technique whenever large densities of atomic vapors or fast modulation of their concentration are required. In this paper, we review the steps that led to this widespread diffusion, from the preliminary observations to some of the most recent applications in fundamental and applied physics.

    Over 40 percent of the energy consumed globally is used in the industrial sector. In China, this sector consumes an even larger proportion, reaching nearly 70 percent in 1997. A variety of energy efficiency policies and programs have been instituted in both industrialized and developing countries in an effort to improve the energy efficiency of the industrial sector. There are very few comprehensive evaluations of these industrial sector energy efficiency policies; however a number of recent workshops and conferences have included a focus on these policies. Three important meetings were the International Energy Agency's Industrial Energy Efficiency: Policies and Programs Conference in 1994, Industrial Energy Efficiency Policies: Understanding Success and Failure - A Workshop Organized by the International Network for Energy Demand Analysis in the Industrial Sector in 1998, and the American Council for an Energy-Efficient Economy's 1999 Summer Study on Energy Efficiency in Industry. Man y articles from these meetings are included as attachments to this memo. This paper provides a brief description of each of seven categories of individual industrial energy efficiency policies and programs, discuss which industrial sectors or types of equipment they apply to, and provide references for articles and reports that discuss each policy or program in more detail. We begin with mandatory-type policies and move to more voluntary-type policies. We then provide a brief description of four integrated industrial energy efficiency policies and provide references for articles and reports that describe these policies in greater detail.

    In this work, atomic calculations were performed within the local-density and generalized-gradient approximations of exchange and correlation density functionals within density-functional theory to provide accurate periodic trends of first ionization energies and electron affinities of the atomic series from hydrogen to xenon. Electronegativities were determined directly from Mulliken's formula and were shown to be equivalently calculated rather by using Slater-Janak's transition state or by calculating the electrostatic self-energies of the orbitals involved in the transition to ions. Finally, comparisons were made with other theoretical and experimental results, including Mulliken-Jaff\\'e's electronegativity scale.

    2001-05-01

    Chinese industrial sector energy-efficiency policy has gone through a number of distinct phases since the founding of the People s Republic in 1949. An initial period of energy supply growth in the 1950s, 1960s, and 1970s was followed by implementation of significant energy efficiency programs in the 1980s. Many of these programs were dismantled in the 1990s during the continuing move towards a market-based economy. In an effort to once again strengthen energy efficiency, the Chinese government passes the Energy Conservation Law in 1997 which provides broad guidance for the establishment of energy efficiency policies. Article 20 of the Energy Conservation Law requires substantial improvement in industrial energy efficiency in the key energy-consuming industrial facilities in China. This portion of the Law declares that ''the State will enhance energy conservation management in key energy consuming entities.'' In 1999, the industrial sector consumed nearly 30 EJ, or 76 percent of China's primary energy. Even though primary energy consumption has dropped dramatically in recent years, due mostly to a decline in coal consumption, the Chinese government is still actively developing an overall policy for energy efficiency in the industrial sector modeled after policies in a number of industrialized countries. This paper will describe recent Chinese government activities to develop industrial sector energy-efficiency targets as a ''market-based'' mechanism for improving the energy efficiency of key industrial facilities.

    Industry contributes directly and indirectly (through consumed electricity) about 37% of the global greenhouse gas emissions, of which over 80% is from energy use. Total energy-related emissions, which were 9.9 GtCO2 in 2004, have grown by 65% since 1971. Even so, industry has almost continuously improved its energy efficiency over the past decades. In the near future, energy efficiency is potentially the most important and cost-effective means for mitigating greenhouse gas emissions from industry. This paper discusses the potential contribution of industrial energy efficiency technologies and policies to reduce energy use and greenhouse gas emissions to 2030.

    Theories of dark energy require a screening mechanism to explain why the associated scalar fields do not mediate observable long range fifth forces. The archetype of this is the chameleon field. Here we show that individual atoms are too small to screen the chameleon field inside a large high-vacuum chamber, and therefore can detect the field with high sensitivity. We derive new limits on the chameleon parameters from existing experiments, and show that most of the remaining chameleon parameter space is readily accessible using atom interferometry.

    Current and future energy demands, end uses, and cost used to characterize typical applications and resultant services in the industrial sector of the United States and 15 selected states are examined. A review and evaluation of existing industrial energy data bases was undertaken to assess their potential for supporting SERI research on: (1) market suitability analysis, (2) market development, (3) end-use matching, (3) industrial applications case studies, and (4) identification of cost and performance goals for solar systems and typical information requirements for industrial energy end use. In reviewing existing industrial energy data bases, the level of detail, disaggregation, and primary sources of information were examined. The focus was on fuels and electric energy used for heat and power purchased by the manufacturing subsector and listed by 2-, 3-, and 4-digit SIC, primary fuel, and end use. Projections of state level energy prices to 1990 are developed using the energy intensity approach. The effects of federal and state industrial energy conservation programs on future industrial sector demands were assessed. Future end-use energy requirements were developed for each 4-digit SIC industry and were grouped as follows: (1) hot water, (2) steam (212 to 300/sup 0/F, each 100/sup 0/F interval from 300 to 1000/sup 0/F, and greater than 1000/sup 0/F), and (3) hot air (100/sup 0/F intervals).

    The rising costs of energy and the risks of uncertain energy supplies are increasingly familiar problems in industry. Bottom line profits and even the simple ability to operate can be affected by spiralling energy costs. An often overlooked alternative is the potential to turn industrial waste or residue into an energy source. On April 9 and 10, 1979, in Claremont, California, the Solar Energy Research Institute (SERI), the California Energy Commission (CEC), and the Western Solar Utilization Network (WSUN) held a workshop which provided industrial managers with current information on using residues and wastes as industrial energy sources. Successful industrial experiences were described by managers from the food processing and forest product industries, and direct combustion and low-Btu gasification equipment was described in detail. These speakers' presentations are contained in this document. Some major conclusions of the conference were: numerous current industrial applications of wastes and residues as fuels are economic and reliable; off-the-shelf technologies exist for converting biomass wastes and residues to energy; a variety of financial (tax credits) and institutional (PUC rate structures) incentives can help make these waste-to-energy projects more attractive to industry. However, many of these incentives are still being developed and their precise impact must be evaluated on a case-by-case basis.

  20. Energy and the English Industrial Revolution.

    Wrigley, E A

    2013-03-13

    Societies before the Industrial Revolution were dependent on the annual cycle of plant photosynthesis for both heat and mechanical energy. The quantity of energy available each year was therefore limited, and economic growth was necessarily constrained. In the Industrial Revolution, energy usage increased massively and output rose accordingly. The energy source continued to be plant photosynthesis, but accumulated over a geological age in the form of coal. This poses a problem for the future. Fossil fuels are a depleting stock, whereas in pre-industrial time the energy source, though limited, was renewed each year.

  1. Atomic Interferometry Test of Dark Energy

    Atomic interferometry can be used to probe dark energy models coupled to matter. We consider the constraints coming from recent experimental results on models generalising the inverse power law chameleons such as $f(R)$ gravity in the large curvature regime, the environmentally dependent dilaton and symmetrons. Using the tomographic description of these models, we find that only symmetrons with masses smaller than the dark energy scale can be efficiently tested. In this regime, the resulting constraints complement the bounds from the E\\"otwash experiment and exclude small values of the symmetron self-coupling.

    Atomic displacement energy Δɛe in multicomponent sheet and lead-silicate glasses is calculated from the free activation energy of a viscous flow. The value of Δɛe is shown to remain constant in a rather wide range of temperatures in the glass transition region. Satisfactory agreement with calculations of Δɛe using the current formula incorporating the glass transition temperature and the fluctuation volume fraction frozen at this temperature is obtained. The validity of the above formula not only at the glass transition temperature but also in the temperature region adjacent to it is confirmed.

    Opening up the market, breaking the monopoly, and allowing the market to decide prices these are the major items on the agenda for the marketization of China's energy industry, and have a direct bearing on national energy security. Research into China's energy security has so far focused on such fields as strategic energy reserves, stability of energy imports, and diversification of import channels. Little has been done in the study of national energy security from the perspective of marketization of the energy industry. However, opening up the energy market and marketizing the energy industry are not only major commitments to China's accession to WTO, they serve the nation's energy security needs as well. This paper takes a look at the actual results of opening up the energy market, the structure of that market, and the nation's energy pricing mechanisms, and on the basis of the findings, raises suggestions on how to tackle the energy security issue.

    Atomic layer etching (ALE) is a technique for removing thin layers of material using sequential reaction steps that are self-limiting. ALE has been studied in the laboratory for more than 25 years. Today, it is being driven by the semiconductor industry as an alternative to continuous etching and is viewed as an essential counterpart to atomic layer deposition. As we enter the era of atomic-scale dimensions, there is need to unify the ALE field through increased effectiveness of collaboration between academia and industry, and to help enable the transition from lab to fab. With this in mind, this article provides defining criteria for ALE, along with clarification of some of the terminology and assumptions of this field. To increase understanding of the process, the mechanistic understanding is described for the silicon ALE case study, including the advantages of plasma-assisted processing. A historical overview spanning more than 25 years is provided for silicon, as well as ALE studies on oxides, III–V compounds, and other materials. Together, these processes encompass a variety of implementations, all following the same ALE principles. While the focus is on directional etching, isotropic ALE is also included. As part of this review, the authors also address the role of power pulsing as a predecessor to ALE and examine the outlook of ALE in the manufacturing of advanced semiconductor devices.

    2015-01-01

    If dark energy---which drives the accelerated expansion of the universe---consists of a new light scalar field, it might be detectable as a "fifth force" between normal-matter objects, in potential conflict with precision tests of gravity. There has, however, been much theoretical progress in developing theories with screening mechanisms, which can evade detection by suppressing forces in regions of high density, such as the laboratory. One prominent example is the chameleon field. We reduce the effect of this screening mechanism by probing the chameleon with individual atoms rather than bulk matter. Using a cesium matter-wave interferometer near a spherical mass in an ultra-high vacuum chamber, we constrain a wide class of dynamical dark energy theories. Our experiment excludes a range of chameleon theories that reproduce the observed cosmic acceleration.

  4. Atom-Interferometry Constraints on Dark Energy

    Science.gov (United States)

    Mueller, Holger

    2016-03-01

    If dark energy is a light scalar field, it might interact with normal matter. The interactions, however, are suppressed in some leading models, which are thus compatible with current cosmological observations as well as solar-system and laboratory studies. Such suppression typically relies on the scalar's interaction with macroscopic amounts of ordinary matter, but can be bypassed by studying the interaction with individual particles. Using an atom interferometer, we have placed tight constraints on so-called chameleon models, ruling out interaction parameters βM > 4 ×104 . This limit is improved by 2.5 orders of magnitude relative to previous experiments. We have already increased the sensitivity of our interferometer hundredfold and are expecting a new constraint soon. Purpose-built experiments in the lab or on the international space station will completely close the gap and rule out out chameleons and other theories, such as axions, dark photons, symmetrons or f (R) gravity.

    1976-01-01

    Discussion of the industrial utilization of geopressured geothermal energy is currently limited by the limited knowledge of the resource's distribution. However, the resource assessment activity in the Bureau of Economic Geology, The University of Texas at Austin, has identified a number of fairway or potential resource zones. These zones are located in Kenedy County; in and about Corpus Christi and Nueces Bays in Nueces, San Patricio, and Aransas Counties; in the coastal zones of Matagorda County; and in a crescent-shaped zone parallel to the coastline in Brazoria and Galveston Counties. The Kenedy and Matagorda County zones are situated in rural areas with little or no industrial activity. The Corpus Christi and Brazoria-Galveston zones are in and adjacent to highly industrialized and urbanized districts. The rural zones will require the establishment of new industries for geothermal fluid utilization while the industrial-urban zones will require either new industry, expansion to existing industry, or modification to existing plant and process. Proposed industries for geothermal fluid utilization can be considered with respect to fitting the industry to the available fluids; this has been the usual approach. An alternate approach is to fit the abailable fluids to the proposed industry. In order to follow the alternate approach requires consideration of ways to upgrade the quality of existing geothermal fluids or geothermal-derived or -energized fluids.

  11. Energy Savings from Industrial Water Reductions

    Energy Technology Data Exchange (ETDEWEB)

    Rao, Prakash; McKane, Aimee; de Fontaine, Andre

    2015-08-03

    Although it is widely recognized that reducing freshwater consumption is of critical importance, generating interest in industrial water reduction programs can be hindered for a variety of reasons. These include the low cost of water, greater focus on water use in other sectors such as the agriculture and residential sectors, high levels of unbilled and/or unregulated self-supplied water use in industry, and lack of water metering and tracking capabilities at industrial facilities. However, there are many additional components to the resource savings associated with reducing site water use beyond the water savings alone, such as reductions in energy consumption, greenhouse gas emissions, treatment chemicals, and impact on the local watershed. Understanding and quantifying these additional resource savings can expand the community of businesses, NGOs, government agencies, and researchers with a vested interest in water reduction. This paper will develop a methodology for evaluating the embedded energy consumption associated with water use at an industrial facility. The methodology developed will use available data and references to evaluate the energy consumption associated with water supply and wastewater treatment outside of a facility’s fence line for various water sources. It will also include a framework for evaluating the energy consumption associated with water use within a facility’s fence line. The methodology will develop a more complete picture of the total resource savings associated with water reduction efforts and allow industrial water reduction programs to assess the energy and CO2 savings associated with their efforts.

    U.S. industry consumes approximately 37 percent of the nation's energy to produce 24 percent of the nation's GDP. Increasingly, industry is confronted with the challenge of moving toward a cleaner, more sustainable path of production and consumption, while increasing global competitiveness. Technology will be essential for meeting these challenges. At some point, businesses are faced with investment in new capital stock. At this decision point, new and emerging technologies compete for capital investment alongside more established or mature technologies. Understanding the dynamics of the decision-making process is important to perceive what drives technology change and the overall effect on industrial energy use. The assessment of emerging energy-efficient industrial technologies can be useful for: (1) identifying R&D projects; (2) identifying potential technologies for market transformation activities; (3) providing common information on technologies to a broad audience of policy-makers; and (4) offering new insights into technology development and energy efficiency potentials. With the support of PG&E Co., NYSERDA, DOE, EPA, NEEA, and the Iowa Energy Center, staff from LBNL and ACEEE produced this assessment of emerging energy-efficient industrial technologies. The goal was to collect information on a broad array of potentially significant emerging energy-efficient industrial technologies and carefully characterize a sub-group of approximately 50 key technologies. Our use of the term ''emerging'' denotes technologies that are both pre-commercial but near commercialization, and technologies that have already entered the market but have less than 5 percent of current market share. We also have chosen technologies that are energy-efficient (i.e., use less energy than existing technologies and practices to produce the same product), and may have additional ''non-energy benefits.'' These benefits are as important (if

    1988-01-01

    This report investigates the state of the US textile industry in terms of energy consumption and conservation. Specific objectives were: To update and verify energy and materials consumption data at the various process levels in 1984; to determine the potential energy savings attainable with current (1984), state-of-the-art, and future production practices and technologies (2010); and to identify new areas of research and development opportunity that will enable these potential future savings to be achieved. Results of this study concluded that in the year 2010, there is a potential to save between 34% and 53% of the energy used in current production practices, dependent on the projected technology mix. RandD needs and opportunities were identified for the industry in three categories: process modification, basic research, and improved housekeeping practices that reduce energy consumption. Potential RandD candidates for DOE involvement with the private sector were assessed and selected from the identified list.

    1978-11-01

    Geothermal energy is currently being used for a number of industrial processes in countries throughout the world. Its application in the United States is mainly limited to space heating even though the temperature of the geothermal fluid is sufficient for process uses, and could be sold at attractive prices while maintaining a high return on investment. The temperature span for industrial use ranges from 40 to 275/sup 0/C, thus encompassing both the abundant low temperature and the less available high temperature resources. Hydrothermal fluids can be used either directly or indirectly dependent upon fluid quality and process needs. The barriers facing hydrothermal industrial process development are (a) the development infrastructure does not exist, (b) energy users are not aware of hydrothermal energy and its advantages, (c) federal incentives are limited, (d) resources are not fully defined.

    Various studies in different countries have shown that significant energy-efficiency improvement opportunities exist in the industrial sector, many of which are cost-effective. These energy-efficiency options include both cross-cutting as well as sector-specific measures. However, industrial plants are not always aware of energy-efficiency improvement potentials. Conducting an energy audit is one of the first steps in identifying these potentials. Even so, many plants do not have the capacity to conduct an effective energy audit. In some countries, government policies and programs aim to assist industry to improve competitiveness through increased energy efficiency. However, usually only limited technical and financial resources for improving energy efficiency are available, especially for small and medium-sized enterprises. Information on energy auditing and practices should, therefore, be prepared and disseminated to industrial plants. This guidebook provides guidelines for energy auditors regarding the key elements for preparing for an energy audit, conducting an inventory and measuring energy use, analyzing energy bills, benchmarking, analyzing energy use patterns, identifying energy-efficiency opportunities, conducting cost-benefit analysis, preparing energy audit reports, and undertaking post-audit activities. The purpose of this guidebook is to assist energy auditors and engineers in the plant to conduct a well-structured and effective energy audit.

    Minimum energy configurations for homonuclear clusters containing from two to twenty-two atoms of six metals, Ag, Au, Cu, Ni, Pd, and Pt have been calculated using the Embedded Atom Method (EAM). The average energy per atom as a function of cluster size has been fit to a liquid drop model, giving estimates of the surface and curvature energies. The liquid drop model gives a good representation of the relationship between average energy and cluster size. As a test the resulting surface energies are compared to EAM surface energy calculations for various low-index crystal faces with reasonable agreement.

    1979-01-01

    A voluntary industrial energy-conservation program was initiated and now includes 50 trade organizations representing over 3,000 companies. Their current reporting system is an effort to respond to the Energy Policy and Conservation Act requirements, as now modified by the National Energy Conservation Policy Act. DOE's Office of Industrial Programs held six workshops in various key locations between November 1978 and February 1979 to enable energy managers to develop ideas and make suggestions that would improve the current and future energy-reporting programs. This report is a summary of the wide range of recommendations that the workshop participants offered as a means of meeting the NECPA requirements and the criticism of the current reporting program. It also reflects industry's views on potential approaches to future reporting. (MCW)

    2013-10-01

    Graphene attracts intensive interest globally across academia and industry since the award of the Nobel Prize in Physics 2010. Within the last half decade, there has been an explosion in the number of scientific publications, patents and industry projects involved in this topic. On the other hand, energy is one of the biggest challenges of this century and related to the global sustainable economy. There are many reviews on graphene and its applications in various devices, however, few of the review articles connect the intrinsic properties of graphene with its energy. The IUPAC definition of graphene refers to a single carbon layer of graphite structure and its related superlative properties. A lot of scientific results on graphene published to date are actually dealing with multi-layer graphenes or reduced graphenes from insulating graphene oxides (GO) which contain defects and contaminants from the reactions and do not possess some of the intrinsic physical properties of pristine graphene. In this review, the focus is on the most recent advances in the study of pure graphene properties and novel energy solutions based on these properties. It also includes graphene metrology and analysis of both intellectual property and the value chain for the existing and forthcoming graphene industry that may cause a new `industry revolution' with the strong and determined support of governments and industries across the European Union, U. S., Asia and many other countries in the world.

    The energy-supply system for California is an integral part of the state's economy, both in terms of energy as a commodity and in the economic effects of expanding requirements for new capital and man-power in the energy sector. It is this notion of an expanding energy system that forms one of the motivations for many of the energy policy discussions and formulations currently taking place. Some of the questions to be addressed are (1) if the energy system is to expand, by how much, and in what particular areas of supply; (2) what are the policy ramifications of certain changes as opposed to others; and (3) what are the major economic effects of changes in energy supply system plans. The purpose of this study is to: (a) describe quantitatively the California energy industry and its relationship to the California and U.S. economies; (b) provide the analytic capability for determining the direct and indirect employment and income impacts resulting from a given energy future for California, and (c) demonstrate and test the methodology with scenarios that embody varying combinations of conventional energy technologies, new energy technologies and energy conservation measures. The methodology developed is generally applicable to any set of specified changes. In this report three alternative energy futures for California are selected in order to quantify their resulting economic impacts.

    Industrial motor-driven systems use more than 2194 billionkWh annually on a global basis and offer one of the largest opportunitiesfor energy savings.1 The International Energy Agency estimates thatoptimization of motor driven systems could reduce global electricitydemand by 7 percent through the application of commercially availabletechnologies and using well-tested engineering practices. Yet manyindustrial firms remain either unaware of or unable to achieve theseenergy savings. The same factors that make it so challenging to achieveand sustain energy efficiency in motor-driven systems (complexity,frequent changes) apply to the production processes that they support.Yet production processes typically operate within a narrow band ofacceptable performance. These processes are frequently incorporated intoISO 9000/14000 quality and environmental management systems, whichrequire regular, independent audits to maintain ISO certification, anattractive value for international trade. It is our contention that acritical step in achieving and sustaining energy efficiency ofmotor-driven systems specifically, and industrial energy efficiencygenerally, is the adoption of a corporate energy management standard thatis consistent with current industrial quality and environmentalmanagement systems such as ISO. Several energy management standardscurrently exist (US, Denmark, Ireland, Sweden) and specifications(Germany, Netherlands) others are planned (China, Spain, Brazil, Korea).This paper presents the current status of energy management standardsdevelopment internationally, including an analysis of their sharedfeatures and differences, in terms of content, promulgation, andimplementation. The purpose of the analysis is to describe the currentstate of "best practices" for this emerging area of energy efficiencypolicymaking and tosuggest next steps toward the creation of a trulyinternational energy management standard that is consistent with the ISOprinciples of measurement

    We investigate the scattering of orthopositronium (o-Ps) atom off different atomic alkali targets (Na to Cs) at low and medium energies (up to 120 eV). Projectile-elastic and target-elastic close-coupling models have been employed to investigate the systems in addition to the static-exchange model. Elastic, excitation and total cross sections have been reported for all four systems. The magnitude of the alkali excitation cross section increases with increasing atomic number of the target atom while the position of the peak value shifts towards lower incident energies. The magnitudes of the Ps excitation and ionization cross sections increase steadily with atomic number with no change in the peak position. The reported results show regular behaviour with increasing atomic number of the target atom. Scattering parameters for the Ps-Rb and Ps-Cs systems are being reported for the first time.

    The local atomic bonding of carbon atoms around the edge of graphene is examined by aberration-corrected scanning transmission electron microscopy (STEM) combined with electron energy loss spectroscopy (EELS). High-resolution 2D maps of the EELS combined with atomic resolution annular dark field STEM images enables correlations between the carbon K-edge EELS and the atomic structure. We show that energy states of graphene edges vary across individual atoms along the edge according to their specific C-C bonding, as well as perpendicular to the edge. Unique spectroscopic peaks from the EELS are assigned to specific C atoms, which enables unambiguous spectroscopic fingerprint identification for the atomic structure of graphene edges with unprecedented detail.

    We investigate the energy spectrum of fermionized bosonic atoms, which behave very much like spinless noninteracting fermions, in optical lattices by means of the perturbation expansion and the retarded Green's function method. The results show that the energy spectrum splits into two energy bands with single-occupation; the fermionized bosonic atom occupies nonvanishing energy state and left hole has a vanishing energy at any given momentum, and the system is in Mott-insulating state with a energy gap.Using the characteristic of energy spectra we obtained a criterion with which one can judge whether the Tonks-Girardeau (TG) gas is achieved or not.

    Six area reported progress in the Energy Efficient Industrialized Housing Research Program during FY 1991. As part of Industry Guidance, meetings were held with steering and technical committees in computers, housing design and manufacturing. This task area enables the program to benefit from the expertise of industry representatives and communicate research results directly to them. As part of the Design Process performance specifications were being developed for the future housing system designed last year. These house designs coordinate and optimize predicted and desirable advances in computerized design processes, materials, components, and manufacturing automation to achieve energy efficiency at reduced first cost. Energy design software were being developed for CAD systems, stressed skin insulating core panel manufacturers; and a prototype energy sales tool. A prototype design was to be developed to integrate one or more subsystems with the building skin. As part of the Manufacturing Process we are developing a manufacturing process simulation and data base to help current and new entrants to the industrialized housing industry in assessing the impact of implementing new manufacturing techniques. For Evaluation we are developing testing plans for six units of housing on the UO campus and the stressed skin insulating core house to be constructed in Oregon. The DOW Chemical test structure will be retrofitted with a tile roof and retested to compare to the dome and conventional construction structures. Calibration of the wind tunnel will be completed so that laboratory tests can be conducted to simulate the ventilation cooling efficiency of houses in design. Research utilization and program management were either aspects of this program.

    The industrial sector consumes 25% of the total energy in the U.S. and produces 18% of the greenhouse gas (GHG) emissions. Energy Systems Integration (ESI) opportunities can reduce those values and increase the profitability of that sector. This presentation outlines several options. Combined heat and power (CHP) is an option that is available today for many applications. In some cases, it can be extended to trigeneration by adding absorbtion cooling. Demand response is another option in use by the industrial sector - in 2012, industry provided 47% of demand response capacity. A longer term option that combines the benefits of CHP with those of demand response is hybrid energy systems (HESs). Two possible HESs are described and development implications discussed. extended to trigeneration by adding absorbtion cooling.

    We study three-body recombination of Ba$^+$ + Rb + Rb in the mK regime where a single $^{138}$Ba$^{+}$ ion in a Paul trap is immersed into a cloud of ultracold $^{87}$Rb atoms. We measure the energy dependence of the three-body rate coefficient $k_3$ and compare the results to the theoretical prediction, $k_3 \\propto E_{\\textrm{col}}^{-3/4}$ where $E_{\\textrm{col}}$ is the collision energy. We find agreement if we assume that the non-thermal ion energy distribution is determined by at least two different micro-motion induced energy scales. Furthermore, using classical trajectory calculations we predict how the median binding energy of the formed molecules scales with the collision energy. Our studies give new insights into the kinetics of an ion immersed into an ultracold atom cloud and yield important prospects for atom-ion experiments targeting the s-wave regime.

    We have developed a new method for determining surface exciton band energies in alkali halides based on velocity-resolved atomic desorption (VRAD). Using this new method, we predict the surface exciton energies for K1, KBr, KC1, and NaC1 within +0.15 eV. Our data, combined with the available EELS data for alkali fluorides, demonstrate a universal linear correlation with the inverse inter-atomic distance in these materials. The results suggest that surface excitons exist in all alkali halides and their excitation energies can be predicted from the known bulk exciton energies and the obtained correlation plot.

    The energy intensive Parmalat dairy processing plant located in Victoriaville, Quebec, produces butter, milk powder, margarine, cheese and condensed milk. Significant energy savings were realized in the past two years through modifications to the production system and by developing energy recovery projects. This paper presents a brief overview of the various projects implemented at the Parmalat dairy processing plant. An economizer was installed on the milk powder dryer which typically used only 50 per cent of the heat to evaporate water from the milk. Careful consideration was given to the selection of the heating medium, Glycol was chosen because it met all the requirements of the food transformation industry. Annual energy savings are estimated at $100,000, at a cost of $125,000 (including equipment and installation costs), for a payback period of 15 months. A better pumping system for the condensed milk increased the return rate by 10 per cent. In addition, the installation of a recovery pipe to preheat water going to an instantaneous water heater resulted in a 10 per cent reduction in steam requirements. Other ongoing projects involve a better electric energy management system, and the implementation of a preventive maintenance program for steam traps.

    A modified static-exchange model is developed to study the collision of an atom with another atom. It includes the effect of long-range dipole–dipole van der Waals interaction between two atoms in addition to the exact effect of short-range force due to Coulomb exchange between two system electrons. Both these interactions dominate at colder energies. The system is treated as a four-centre problem in the centre-of-mass frame. The present ab-initio model is useful to study the two-atomic collisions at low energies, as well as cold energies. The new code is applied to study the scattering of positronium (Ps) by hydrogen (H), both in their ground states.

    Atom interferometry experiments are searching for evidence of chameleon scalar fields with ever-increasing precision. As experiments become more precise, so too must theoretical predictions. Previous work has made numerous approximations to simplify the calculation, which in general requires solving a three-dimensional nonlinear partial differential equation. This paper calculates the chameleonic force using a numerical relaxation scheme on a uniform grid. This technique is more general than previous work, which assumed spherical symmetry to reduce the partial differential equation to a one-dimensional ordinary differential equation. We examine the effects of approximations made in previous efforts on this subject and calculate the chameleonic force in a setup that closely mimics the recent experiment of Hamilton et al. Specifically, we simulate the vacuum chamber as a cylinder with dimensions matching those of the experiment, taking into account the backreaction of the source mass, its offset from the center, and the effects of the chamber walls. Remarkably, the acceleration on a test atomic particle is found to differ by only 20% from the approximate analytical treatment. These results allow us to place rigorous constraints on the parameter space of chameleon field theories, although ultimately the constraint we find is the same as the one we reported in Hamilton et al. because we had slightly underestimated the size of the vacuum chamber. This computational technique will continue to be useful as experiments become even more precise and will also be a valuable tool in optimizing future searches for chameleon fields and related theories.

    The"11th Five-Year"plan sets the objective of reducing energy consumption per unit of GDP by 20% in five years.Readjusting industrial structure is one of the possible means to reach this goal.As for energy consumption reduction through industrial readjustment,however,present research only explores the effects of industry structural change in the six sectors such as agriculture,industry,construction,transportation and commerce,yet without considering the ramifications of sub-sector two-digit code industry structure.In this paper,we have calculated the effects of structural change in light- heavy industries on energy consumption and energy intensity from 1993 to 2005 using the factor decomposition method.As a result,we found for each percentage point gain in favour of heavy industry in the light-heavy industry mix,China’s energy consumption increases by nearly 9 million metric tons of coal equivalent.However the overall effects of structural change in light-heavy industry are less than those of sub-sector intensity factors on industrial energy intensity and energy consumption per unit of GDP.The heavy industry share gain has over recent years exerted a significant impact on industrial energy intensity.For example,78% of the abnormal increase in industrial energy intensity in 2003 could be attributed to this factor.Finally,an analytical framework for energy intensity based on this study is presented.

    Atom interferometry experiments are searching for evidence of chameleon scalar fields with ever-increasing precision. As experiments become more precise, so too must theoretical predictions. Previous work has made numerous approximations to simplify the calculation, which in general requires solving a 3-dimensional nonlinear partial differential equation (PDE). In this paper, we introduce a new technique for calculating the chameleonic force, using a numerical relaxation scheme on a uniform grid. This technique is more general than previous work, which assumed spherical symmetry to reduce the PDE to a 1-dimensional ordinary differential equation (ODE). We examine the effects of approximations made in previous efforts on this subject, and calculate the chameleonic force in a set-up that closely mimics the recent experiment of Hamilton et al. Specifically, we simulate the vacuum chamber as a cylinder with dimensions matching those of the experiment, taking into account the backreaction of the source mass, its o...

  16. An atomic clockwork using phase dependent energy shifts

    2011-01-01

    A frequency stabilized laser referenced to an unperturbed atomic two level system acts as the most accurate clock with femtosecond clock ticks. For any meaningful use, a Femtosecond Laser Frequency Comb (FLFC) is used to transfer the atomic clock accuracy to electronically countable nanosecond clock ticks. Here we propose an alternative clockwork based on the phenomenon that when an atomic system is slowly evolved in a cyclic path, the atomic energy levels gather some phase called the geometric phase. This geometric phase dependent energy shift has been used here to couple the two frequency regimes in a phase coherent manner. It has also been shown that such a technique can be implemented experimentally, bypassing the highly involved setup of a FLFC.

    The international workshop on Policy Modeling for Industrial Energy Use was jointly organized by EETA (Professional Network for Engineering Economic Technology Analysis) and INEDIS (International Network for Energy Demand Analysis in the Industrial Sector). The workshop has helped to layout the needs and challenges to include policy more explicitly in energy-efficiency modeling. The current state-of-the-art models have a proven track record in forecasting future trends under conditions similar to those faced in the recent past. However, the future of energy policy in a climate-restrained world is likely to demand different and additional services to be provided by energy modelers. In this workshop some of the international models used to make energy consumption forecasts have been discussed as well as innovations to enable the modeling of policy scenarios. This was followed by the discussion of future challenges, new insights in the data needed to determine the inputs into energy model s, and methods to incorporate decision making and policy in the models. Based on the discussion the workshop participants came to the following conclusions and recommendations: Current energy models are already complex, and it is already difficult to collect the model inputs. Hence, new approaches should be transparent and not lead to extremely complex models that try to ''do everything''. The model structure will be determined by the questions that need to be answered. A good understanding of the decision making framework of policy makers and clear communication on the needs are essential to make any future energy modeling effort successful. There is a need to better understand the effects of policy on future energy use, emissions and the economy. To allow the inclusion of policy instruments in models, evaluation of programs and instruments is essential, and need to be included in the policy instrument design. Increased efforts are needed to better understand the

    The report describes the completed survey and the methodology used for the analysis of energy saving opportunities and potentials for processing technologies and equipment in the industry. The report also includes a total of fourteen technology descriptions, of which eleven relate to end use of energy, while the three descriptions are for cross-technologies. The technology descriptions analyse any significant savings opportunities in the processing technologies concerned and work out the potentials of 'here and now' cost savings, with 2, 4 and 10-year payback time, respectively. The survey makes it possible to prioritize the instruments with the shortest payback times. The total savings potential for the eleven end-use technologies is estimated to be 10% at 2 years of payback time, 15% at four year payback time, and 32% at the 10 year payback time. The percentage potential is somewhat greater for the end-use technologies using electricity than the end-use which mainly uses fuel. That the potential is less for fuel-based end-use technologies may be explained by the fact that they are key processes that are regularly upgraded to increase product quality, to reduce production time and waste, etc. Such improvements also help to save energy and means that further improvements are relatively expensive.

    Experimental and theoretical research has been initiated at the Princeton Plasma Physics Laboratory on the electrostatic atomization process in collaboration with Charged Injection Corporation. The goal of this collaboration is to set up a comprehensive research and development program on the electrostatic atomization at the Princeton Plasma Physics Laboratory so that both institutions can benefit from the collaboration. Experimental, theoretical and numerical simulation approaches are used for this purpose. An experiment consisting of a capillary sprayer combined with a quadrupole mass filter and a charge detector was installed at the Electrostatic Atomization Laboratory to study fundamental properties of the charged droplets such as the distribution of charges with respect to the droplet radius. In addition, a numerical simulation model is used to study interaction of beam electrons with atmospheric pressure water vapor, supporting an effort to develop an electrostatic water mist fire-fighting nozzle.

    The factors, by which the modern engineering ethics has been profoundly affected, were classified to three categories, namely mental blow, the destruction of human function and environment damage. The role of atomic energy engineering in the ethic field has been shown in the first place. It is pointed out that it has brought about the mental blow by the elucidation of universal truth and discipline and the functional disorder by the power supply. However, the direct effect of radiation to the human kinds is only a part of the stresses comparing to the accumulation of the social stress which should be taken into account of by the possibility of disaster and the suspicion of the atomic energy politics. An increase in the multiple stresses as well as the restriction of criticism will place obstacles on the promotion of atomic energy. (author)

    2017-03-31

    In this contribution, we discuss how reaction energy benchmark sets can automatically be created from arbitrary atomization energy databases. As an example, over 11 000 reaction energies derived from the W4-11 database, as well as some relevant subsets are reported. Importantly, there is only very modest computational overhead involved in computing >11 000 reaction energies compared to 140 atomization energies, since the rate-determining step for either benchmark is performing the same 140 quantum chemical calculations. The performance of commonly used electronic structure methods for the new database is analyzed. This allows investigating the relationship between the performances for atomization and reaction energy benchmarks based on an identical set of molecules. The atomization energy is found to be a weak predictor for the overall usefulness of a method. The performance of density functional approximations in light of the number of empirically optimized parameters used in their design is also discussed.

    California has a large number of small and medium sized industries which have a major impact on the demand growth of California utilities. Energy use in building services (lighting, HVAC, office equipment, computers, etc.). These industries constitute an important but largely neglected fraction of the total site energy use. The ratio of energy use in building service to the total site energy use is a function of the industrial activity, its size, and the climate at the site of the facility. Also, energy use in building services is more responsive to weather and occupant schedules than the traditional base-load'' industrial process energy. Industrial energy use is considered as a base-load'' by utility companies because it helps to increase the utilities' load factor. To increase this further, utilities often market energy at lower rates to industrial facilities. Presently, the energy use in the building services of the industrial sector is often clubbed together with industrial process load. Data on non-process industrial energy use are not readily available in the literature. In cases where the major portion of the energy is used in the building services (with daily and seasonal load profiles that in fact peak at the same time as systemwide load peaks), the utility may be selling below cost at peak power times. These cases frequently happen with electric utilities. 30 figs., 6 tabs.

    2015-05-01

    We study a single atom as an open quantum system, which is initially prepared in a coherent state of low energy and oscillates in a one-dimensional harmonic trap through an interacting ensemble of NA bosons, held in a displaced trap [arXiv:1410.8676]. The non-equilibrium quantum dynamics of the total system is simulated by means of an ab-initio method, giving us access to all properties of the open system and its finite environment. In this talk, we focus on unraveling the interplay of energy exchange and correlations between the subsystems, which are coupled in such a spatio-temporally localized manner. We show that an inter-species interaction-induced level splitting accelerates the energy transfer between the atomic species for larger NA, which becomes less complete at the same time. System-environment correlations prove to be significant except for times when the excess energy distribution among the subsystems is highly imbalanced. These correlations result in incoherent energy transfer processes, which accelerate the early energy donation of the single atom. By analyzing correlations between intra-subsystem excitations, certain energy transfer channels are shown to be (dis-)favored depending on the instantaneous direction of transfer.

    The interactions between coulpled atoms and a single mode of a quantized electromagnetic field, which involve the terms originating from the dipole interactions, are discussed. In the usual Jaynes-Cummings model for coupled atoms, the terms of non-conservation of energy originating from dipole interactions are neglected, however, we take them into consideration in this paper. The effects of these terms on the evolutions of quantum statistic properties and squeezing of the field, the squeezing of atomic dipole moments and atomic population inversion are investigated. It has been shown that the coupling between atoms modulates these evolutions of fields and atoms. The terms of non-conservation of energy affect these evolutions of field and atoms slightly. They also have effects on the squeezing of the field, the squeezing of atomic dipole and atomic population inversions. The initial states of atoms also affect these properties.

    An assumptive theoretical relationship is suggested to describe the property of molecular atomization energy and energy transfer rate in the initiation of explosions. To investigate the relationship between atomization energy and energy transfer rate, the number of doorway modes of explosives is estimated by the theory of Dlott and Fayer in which the rate is proportional to the number of normal mode vibrations. It was evaluated frequencies of normal mode vibrations of eight molecules by means of density functional theory (DFT) at the b3p86/6-31G(d,p) level. It is found that the number of doorway modes shows a linear correlation to the atomization energies of the molecules, which were also calculated by means of the same method. A mechanism of this correlation is discussed. It is also noted that in those explosives with similar molecular structure and molecular weight, the correlation between the atomization energy and the number of doorway modes is higher.

    2014-02-15

    Accurate electrostatics necessitates the use of multipole moments centered on nuclei or extra point charges centered away from the nuclei. Here, we follow the former alternative and investigate the convergence behavior of atom-atom electrostatic interactions in the pilot protein crambin. Amino acids are cut out from a Protein Data Bank structure of crambin, as single amino acids, di, or tripeptides, and are then capped with a peptide bond at each side. The atoms in the amino acids are defined through Quantum Chemical Topology (QCT) as finite volume electron density fragments. Atom-atom electrostatic energies are computed by means of a multipole expansion with regular spherical harmonics, up to a total interaction rank of L = ℓA+ ℓB + 1 = 10. The minimum internuclear distance in the convergent region of all the 15 possible types of atom-atom interactions in crambin that were calculated based on single amino acids are close to the values calculated from di and tripeptides. Values obtained at B3LYP/aug-cc-pVTZ and MP2/aug-cc-pVTZ levels are only slightly larger than those calculated at HF/6-31G(d,p) level. This convergence behavior is transferable to the well-known amyloid beta polypeptide Aβ1-42. Moreover, for a selected central atom, the influence of its neighbors on its multipole moments is investigated, and how far away this influence can be ignored is also determined. Finally, the convergence behavior of AMBER becomes closer to that of QCT with increasing internuclear distance.

    An industrial sector uses more energy than any other end-use sectors and currently this sector is consuming about 37% of the world's total delivered energy. Energy is consumed in the industrial sector by a diverse group of industries including manufacturing, agriculture, mining, and construction and for a wide range of activities, such as processing and assembly, space conditioning, and lighting. This paper presents a comprehensive literature review about industrial energy saving by management, technologies and policies. Latest literatures in terms of thesis (MS and PhD), journal articles, conference proceedings, web materials, reports, books, handbooks on industrial energy management, policies and energy savings strategies have been compiled. Energy saving by management including energy audit, training programs and housekeeping beside some energy management practices in the world has been reviewed. Energy saving technologies, such as use of high efficiency motors (HEMs), variable speed drives (VSDs), economizers, leak prevention and reducing pressure drop has been reviewed. Based on energy saving technologies results, it has been found that in the industrial sectors, a sizeable amount of electric energy, emissions and utility bill can be saved using these technologies. Payback periods for different energy savings measures have been identified and found to be economically viable in most cases. Finally, various energy-saving policies for few selected countries were reviewed. (author)

    A single-equation model is developed and employed for forecasting industrial electric energy consumption in the Saudi Consolidated Electric Company in the Eastern Province (SCECO-East) of Saudi Arabia. SCECO-East's industrial loads are composed mainly of oil-related and petrochemical industries. Even though industrial loads are generally characterised by their steadiness, the harsh weather conditions of the Eastern Province cause great variations in the industrial electric energy consumption at SCECO-East. The developed model reflects these variations. MATLAB is used to solve the model. (Author)

  10. Success factors of energy management in energy-intensive industries. Energy performance measurement

    2011-10-15

    This thesis explores energy performance measurement in support of energy management in the energy-intensive industries. In general, performance measurement is used in management for raising awareness, evaluating performance, setting targets and offering decision support. These purposes also apply to energy management, defined here as the management of all activities related to the economic and responsible use of energy in an organisation. This thesis answers the following three questions: 1) what is the concept of energy performance in a business organisation? 2) what is the importance of energy performance measurement to energy management in the energy-intensive industries? and 3) what are the subsequent needs for future research and development? A variety of methods are used, ranging from qualitative research to the modelling of energy systems and case demonstrations. The findings indicate that energy management should focus on improving energy performance, not energy efficiency, because this broader view is able to capture both the operational and strategic perspectives of energy management. This is in line with the trends of managerial integration and the adoption of sustainable development into management practice. The domain of energy performance indicators should entail organisational, systemic and temporal dimensions. From the perspective of operational management, performance measurement should address all the three means to improve energy performance, namely technology, operation and process integration. In addition to the operational management, future research and development should define the role of energy performance measurement in all the other management functions. These recommendations provide a wide spectrum of opportunities for the development of energy performance indicators, energy performance measurement systems and their underlying deployment processes in different industrial sectors, organisations and systems.

    Results of a survey to determine the potential applicability of solar thermal energy to industrial processes in California are presented. It is found that if the heat for all industrial processes at temperatures below 212 F were supplied by solar energy, total state energy consumption could be reduced by 100 trillion Btus (2%), while the use of solar energy in processes between 212 and 350 F could displace 500 trillion Btus. The issues and problems with which solar energy must contend are illustrated by a description of fluid milk processing operations. Solar energy application is found to be technically feasible for processes with thermal energy requirements below 212 F, with design, and degree of technical, economic and management feasibility being site specific. It is recommended that the state provide support for federal and industrial research, development and demonstration programs in order to stimulate acceptance of solar process heat application by industry.

    Mutation breeders in the 1960s seemed poised to use atomic energy to speed up mutation rates in plants in order to develop new crop varieties, for the benefit of all people. Although skepticism had slowed this work in the United States, the International Atomic Energy Agency (IAEA) nurtured the scientific field, its community of experts, and an imagined version of the future that put humans in control of their destiny. The IAEA acted as a center of dissemination and support for experts and ideas even when they had fallen from favor elsewhere. Through the lens of the IAEA, plant breeding bore the appearance of a socially progressive, ultra-modern science destined to alleviate population pressures. Administrators at the IAEA also were desperate for success stories, hoping to highlight mutation plant breeding as a potential solution to the world's ills. The community of mutation plant breeders gained a lifeline from the consistent clarion call from the Vienna-based agency to use atomic energy to understand the natural world and quicken its pulse with radioisotopes.

    A more general exponential cosine screened Coulomb potential is used for the first time to investigate the screening effects on the hydrogen atom in plasmas. This potential is examined for four different cases that correspond to four different type potentials when the different parameters are used in the potential within the framework of the well-known asymptotic iteration method. By solving the corresponding the radial Schroedinger equation with the screened and exponential cosine screened Coulomb potentials and comparing the obtained energy eigenvalues with the results of other studies, the applicability of the method to this kind of plasma physics problem is shown. The energy values of more general exponential cosine screened Coulomb potential are presented for various parameters in the potential. One of the advantages of the present potential is that it exhibits stronger screening effect than that of the exponential cosine screened Coulomb potential and it is also reduced to screened Coulomb and exponential cosine screened Coulomb as well as Coulomb potentials for special values of parameters. The parameters in the potential would be useful to model screening effects which cause an increase or decrease in the energy values of hydrogen atom in both Debye and quantum plasmas and in this manner this potential would be useful for the investigations of the atomic structure and collisions in plasmas.

    Industrial sector is the largest user of energy in India and many parts of the world. More than half of the total energy is used in industries to operate various energy-using machineries. Energy conservation is a cost-effective approach in any energy optimization program that can be implemented in industrial activities. Energy-intensive industries in developing economies offer significant energy-saving potential owing to the technology gap as well as lower operating efficiency. A detailed energy flow analysis was conducted in a paper carton manufacturing unit in India to quantify the energy-saving potential. The study revealed that the compressed air leakage is responsible for about 50% of the total energy loss. The specific electrical and thermal energy consumption was estimated and found to be 91.85 kWh/ton and 1,619 MJ/ton of biomass, respectively. Annual energy saving potential was found to be 5.9% of the total annual energy consumption. The cost of DG power is found to be 389% higher than the grid power. The share of self-generated DG power is estimated to be 41% of the total power consumed. Electrical energy intensity of the plant could be reduced by 6.36% implementing energy conservation measures proposed in this study. (orig.)

The main tools available for this task are energy efficiency, renewable energy, and clean energy technologies and services, which are collectively known as sustainable energy. To unleash this potential, the US and other governments need the full cooperation of the sustainable energy industry. This industry knows more than most other about turning energy-related pollution prevention into profits. If engaged, they can help: (1) Identify the economic benefits of greenhouse gas mitigation; (2) Identify barriers to the implementation of greenhouse gas mitigation projects; (3) Develop policies and measures to overcome these barriers; and (4) Implement greenhouse gas mitigation projects. 7 refs.

    We present a derivation of the total cross section for inelastic scattering of low-energy solar neutrinos and reactor antineutrinos on bound electrons, resulting in a transition of the electron to an excited state. The atomic-shell structure of various chemical elements is treated in terms of a nonrelativistic approximation. We estimate the interaction rates for modern neutrino detectors, in particular the Borexino and GEMMA experiments. We establish that in these experiments the effect can be safely neglected, but it could be accessible to future large-volume neutrino detectors with low energy threshold.

    This report examines several different measures of industrial output for use in constructing estimates of industrial energy efficiency and discusses some reasons for differences between the measures. Estimates of volume-based measures of output, as well as 3 value-based measures of output (value of production, value of shipments, and value added), are evaluated for 15 separate 4-digit industries. Volatility, simple growth rate, and trend growth rate estimates are made for each industry and each measure of output. Correlations are made between the volume- and value-based measures of output. Historical energy use data are collected for 5 of the industries for making energy- intensity estimates. Growth rates in energy use, energy intensity, and correlations between volume- and value-based measures of energy intensity are computed. There is large variability in growth trend estimates both long term and from year to year. While there is a high correlation between volume- and value-based measures of output for a few industries, typically the correlation is low, and this is exacerbated for estimates of energy intensity. Analysis revealed reasons for these low correlations. It appears that substantial work must be done before reliable measures of trends in the energy efficiency of industry can be accurately characterized.

    Industry consumes a significant percentage of the total electric energy consumption both nationally and in the Pacific Northwest. However, industrial demand-side management (DSM) activities in this sector are underdeveloped and typically concentrate on new technologies and new equipment. An overlooked opportunity for electric resource development is through operations and maintenance (O and M) activities. The purpose of this project is to determine the industrial DSM potential that may be achieved through O and M practices both in the US and the Pacific Northwest. The overall goal of the project is to identify, quantify, confirm, and develop conservation resources that can be achieved from the industrial sector through O and M practices and energy measures. The results of the study identify a significant electric resource potential available through improved O and M activities in industry. Several O and M type energy-saving measures that increase efficiencies and reduce loads are identified and estimates of potential energy savings associated with each measure are presented. Systems identified with the most potential include compressed-air systems; motors and motor drives; lighting; heating, ventilating and air conditioning (HVAC); and control systems. The results of the research show that industrial electric energy consumption can be notably reduced by implementing key O and M type energy measures. Specifically, the results of industrial energy audits, case studies, and other published sources indicate that reductions in energy consumption from improved O and M activities can average between 8% and 12.5%.

    The functional properties of transition metal dichalcogenides (TMDs) may be promoted by the inclusion of other elements. Here, we studied the local stoichiometry of single cobalt promoter atoms in an industrial-style MoS2-based hydrotreating catalyst. Aberration-corrected scanning transmission electron microscopy and electron energy loss spectroscopy show that the Co atoms occupy sites at the (-100) S edge terminations of the graphite-supported MoS2 nanocrystals in the catalyst. Specifically, each Co atom has four neighboring S atoms that are arranged in a reconstructed geometry, which reflects an equilibrium state. The structure agrees with complementary studies of catalysts that were prepared under vastly different conditions and on other supports. In contrast, a small amount of residual Fe in the graphite is found to compete for the S edge sites, so that promotion by Co is strongly sensitive to the purity of the raw materials. The present single-atom-sensitive analytical method therefore offers a guide for advancing preparative methods for promoted TMD nanomaterials.

    In a developed economy, improving the energy performance of the industry sector can make an important contribution to achieving national energy efficiency goals. Policy measures aimed at increasing energy efficiency in industry must be proven to be effective. In Ireland one such measure is the Large Industry Energy Network (LIEN) programme. LIEN is a voluntary network of large energy users, facilitated by the national energy agency, working to maintain strong energy management practices. In this paper, we combine top-down methods for analysing national energy statistics with company-level figures supplied by LIEN participants to quantify the energy savings achieved by the companies and to determine the fraction of national savings that can be attributed to them. By comparing the collective performance of participant companies with the performance of the rest of industry we provide an indication of the effectiveness of the programme and quantify the savings that may be directly attributable to it. These figures when combined with national energy forecasts for industry help us assess the likely contribution of the programme to future national energy savings targets.

    Research on conditions to develop new innovations within emerging renewable energy industries is often done with a national focus. However, recent research on international entrepreneurship has revealed that firms operate on international levels very early in their life time. Thus, based on former research on international entrepreneurship and case examples, we build the propositions that firms in the marine energy industry use internationalization as a strategy to overcome industry barriers. Our primary source of data is a unique dataset from a global survey of all the companies in the marine energy industry who are aiming to commercialize a wave or tidal energy device. This paper is organized in two steps: first we identified the most challenging industry barriers perceived by companies. Second we use these to form propositions which we assess through empirical data. The two most challenging barriers perceived by the companies are need for capital and need for supportive political schemes. Our findings reveal that internationalization certainly is a common strategy to access capital and attractive support schemes in foreign countries. The early internationalization has implications for researchers, managers and policy makers. - Research highlights: {yields} Industry barriers identified as access to capital and supportive political schemes. {yields} International entrepreneurship is used to overcome industry barriers. {yields} Start-ups in emerging energy industries 'shop' national support schemes. {yields} Future research to provide policy advice should adapt to the international reality. {yields} Research based on a worldwide survey of wave and tidal energy device developers.

    2016-06-02

    Vibrational energy flow in proteins was studied by monitoring the time-resolved anti-Stokes ultraviolet resonance Raman scattering of three myoglobin mutants in which a Trp residue substitutes a different amino acid residue near heme. The anti-Stokes Raman intensities of the Trp residue in the three mutants increased with similar rates after depositing excess vibrational energy at heme, despite the difference in distance between heme and each substituted Trp residue along the main chain of the protein. This indicates that vibrational energy is not transferred through the main chain of the protein but rather through atomic contacts between heme and the Trp residue. Distinct differences were observed in the amplitude of the band intensity change between the Trp residues at different positions, and the amplitude of the band intensity change exhibits a correlation with the extent of exposure of the Trp residue to solvent water. This correlation indicates that atomic contacts between an amino acid residue and solvent water play an important role in vibrational energy flow in a protein.

    Full Text Available The Brazilian government has been promoting energy efficiency measures for industry since the eighties but with very limited returns, as shown in this paper. The governments of some other countries dedicated much more effort and funds for this area and reached excellent results. The institutional arrangements and types of programmes adopted in these countries are briefly evaluated in the paper and provide valuable insights for several proposals put forward here to make more effective the Brazilian government actions directed to overcome market barriers and improve energy efficiency in the local industry. The proposed measures include the creation of Industrial Assessment Centres and an executive agency charged with the coordination of all energy efficiency programmes run by the Federal government. A large share of the Brazilian industry energy consumption comes from energy-intensive industrial branches. According to a recent survey, most of them have substantial energy conservation potentials. To materialize a fair amount of them, voluntary targets concerning energy efficiency gains should start to be negotiated between the Government and associations representing these industrial branches. Credit facilities and tax exemptions for energy-efficient equipment’s should be provided to stimulate the interest of the entrepreneurs and the setting-up of bolder targets.

    Breweries in the United States spend annually over $200 Million on energy. Energy consumption is equal to 3-8% of the production costs of beer, making energy efficiency improvement an important way to reduce costs, especially in times of high energy price volatility. After a summary of the beer making process and energy use, we examine energy efficiency opportunities available for breweries. We provide specific primary energy savings for each energy efficiency measure based on case studies that have implemented the measures, as well as references to technical literature. If available, we have also listed typical payback periods. Our findings suggest that there may still be opportunities to reduce energy consumption cost-effectively for breweries. Major brewing companies have and will continue to spend capital on cost effective measures that do not impact the quality of the beer. Further research on the economics of the measures, as well as their applicability to different brewing practices, is needed to assess implementation of selected technologies at individual breweries.

    We study classical bremsstrahlung from neutral atoms and investigate the features characteristic for the low incident energy region. These features include oscillations in the energy dependence of the bremsstrahlung cross section and structures in the asymmetry parameter of radiation. We use soft-photon limit results to elucidate the physical origins of the features. We show that there is a correspondence between classical and quantum results [1]. In both cases the features result from the suppression of contributions to the radiation from certain angular momenta at certain energies. In quantum mechanics this corresponds to zeroes in certain radiation matrix elements. In the classical case the lack of contribution from some interval of angular momentum is caused by behaviors of elastic electron scattering in screened potentials. [1] A. Florescu, O. I.

    The textile industry is one of the most complicated manufacturing industries because it is a fragmented and heterogeneous sector dominated by small and medium enterprises (SMEs). Energy is one of the main cost factors in the textile industry. Especially in times of high energy price volatility, improving energy efficiency should be a primary concern for textile plants. There are various energy-efficiency opportunities that exist in every textile plant, many of which are cost-effective. However, even cost-effective options often are not implemented in textile plants mostly because of limited information on how to implement energy-efficiency measures, especially given the fact that a majority of textile plants are categorized as SMEs and hence they have limited resources to acquire this information. Know-how on energy-efficiency technologies and practices should, therefore, be prepared and disseminated to textile plants. This guidebook provides information on energy-efficiency technologies and measures applicable to the textile industry. The guidebook includes case studies from textile plants around the world and includes energy savings and cost information when available. First, the guidebook gives a brief overview of the textile industry around the world, with an explanation of major textile processes. An analysis of the type and the share of energy used in different textile processes is also included in the guidebook. Subsequently, energy-efficiency improvement opportunities available within some of the major textile sub-sectors are given with a brief explanation of each measure. The conclusion includes a short section dedicated to highlighting a few emerging technologies in the textile industry as well as the potential for the use of renewable energy in the textile industry.

    A trial project aimed at using waste hot water from the cooling process at a Scottish whisky distillery to heat a glasshouse for tomato production is described. Later developments have involved the installation of a waste heat boiler to make use of the heat from the still burner flue gases. Steam from the boiler is used within the distillery and to supplement the glasshouse system. The payback within the distillery industry has been excellent, but tomato production, though continuing, was adversely affected by severe cutbacks in distillery production in the early eighties. Recently further significant savings have been made in the distillery industry by the installation of a regenerative burner in one of the stills and thermo-compressors in the cooling tower condensers to produce low pressure steam which can be fed back into the system.

    With economic development and the change of industrial structure, industrial relocation is an inevitable trend. In the process of industrial relocation, environmental externality and social cost could occur due to market failure and government failure. Little attention has been paid to this issue. In this paper, we address it with a theoretical analysis and an empirical investigation on the relationship between China's industrial relocation in the early 1990s and energy consumption which is the primary source of CO{sub 2} emission, an environmental externality that causes increasing concerns. The macro-policy analysis suggests that there would be a positive link between China's industrial relocation in the early 1990s and energy saving (and environmental externalities reduction). Using fixed-effect regression model and simulation method, we provide an empirical support to this argument. In order to further reduce environmental externalities and social cost in the process of industrial relocation, we provide policy suggestions as follows: First, strengthen the evaluation of environmental benefits/costs; Second, pay more attention to the coordinated social-economic development; Third, avoid long-lived investment in high-carbon infrastructure in areas with industries moved in; Fourth, address employment issue in the areas with industries moved out. - Research highlights: {yields} Little attention has been paid to the linkage between industrial relocation and environmental externality. {yields} Our macro-policy analysis suggests that there would be a positive link between China's industrial relocation in the early 1990s and energy saving (and environmental externalities reduction). {yields} Using fixed-effect regression model and simulation method, we find a positive link between China's industrial relocation in the early 1990s and energy saving. {yields} Policy suggestions to further reduce environmental externalities and social cost in the process

    @@ The coupled-channel optical method is used to study positron scattering by atomic lithium at energies ranging from the ionization threshold to 60 eV. The present method simultaneously treats the target channels and the positronium (Ps) channels in the coupled-channel method together with the continuum effects via an ab-initio optical potential. Ionization, elastic and inelastic cross sections in target channels, and the total cross section are also reported and compared with other theoretical and experimental data. A comparative study with the corresponding electron-lithium data is also reported.

    We performed embedded atom method calculations on surface energies and unstable stacking fault energies for a series of intermetallics for which interatomic potentials of the embedded atom type have recently been developed. These results were analyzed and applied to the prediction of relative ductility of these materials using the various current theories. Series of alloys with the B2 ordered structure were studied, and the results were compared to those in pure body-centered cubic (bcc) Fe. Ordered compounds with L1{sub 2} and L1{sub 0} structures based on the face-centered cubic (fcc) lattice were also studied. It was found that there is a correlation between the values of the antiphase boundary (APB) energies in B2 alloys and their unstackable stacking fault energies. Materials with higher APB energies tend to have higher unstable stacking fault energies, leading to an increased tendency to brittle fracture. {copyright} {ital 1997 Materials Research Society.}

    About 37% of the primary energy consumed both in the U.S. and globally is used by the industrial sector. A variety of energy efficiency policies and programs have been implemented throughout the world in an effort to improve the energy efficiency of this sector. This report provides an overview of these policies and programs in twelve industrialized nations and the European Union (EU). We focus on energy efficiency products and services that are available to industrial consumers, such as reports, guidebooks, case studies, fact sheets, profiles, tools, demonstrations, roadmaps and benchmarking. We also focus on the mechanisms to communicate the availability and features of these products and services and to disseminate them to the industrial consumers who can use them. Communication channels include customer information centers and websites, conferences and trade shows, workshops and other training mechanisms, financial assistance programs, negotiated agreements, newsletters, publicity, assessments, tax and subsidy schemes and working groups. In total, over 30 types of industrial sector energy efficiency products, services and delivery channels have been identified in the countries studied. Overall, we found that the United States has a large variety of programs and offers industry a number of supporting programs for improving industrial energy efficiency. However, there are some products and services found in other industrialized countries that are not currently used in the U.S., including benchmarking programs, demonstration of commercialized technologies and provision of energy awareness promotion materials to companies. Delivery mechanisms found in other industrialized countries that are not employed in the U.S. include negotiated agreements, public disclosure and national-level tax abatement for energy-efficient technologies.

The goal was to build a model that can be applied to all industrial sites inthe Mediterranean area. The approach followed to achieve the objectives was to study allthe new technologies and systems that, if applied globally, can make the whole areasustainable both energetically and environmentally. The application of the model allowsthe design and implementation of self-sufficient green areas in terms of energy which alsobrings to the reduction of the emissions into the atmosphere. An aim of the project wasalso to identify possible sources of funding or incentives. The main beneficiaries of theresults are SMEs that through a more responsible approach to the environment could getgreater market competitiveness and reduce energy costs of their enterprises. Otherbeneficiaries are the people who obtain advantages from a clearer and less pollutedsurrounding environment.The paper presents the results obtained from the application of the model in some pilotcases.

  11. Many-body approximations for atomic binding energies

    Schuster, Micah D; Staker, Joshua T

    2011-01-01

    We benchmark three approximations for the many-body problem -- the Hartree-Fock, projected Hartree-Fock, and random phase approximations -- against full numerical configuration-interaction calculations of the electronic structure of atoms, from Li through to Ne. Each method uses exactly the same input, i.e., the same single-particle basis and Coulomb matrix elements, so any differences are strictly due to the approximation itself. Although it consistently overestimates the ground state binding energy, the random phase approximation has the smallest overall errors; furthermore, we suggest it may be useful as a method for efficient optimization of single-particle basis functions.

    The authors examine the effectiveness of regulation in the electrical energy industry in the U.S. On the whole, the industry is not allowed to act as a spatial monopolist. It is not justifiable, however, to conclude that monopolistic tendencies are absent. In particular, the pricing structure departs from the competitive criterion, which requires price to equal the marginal cost of supplying electrical energy to a given consumer.

    This paper analyses the trends in energy consumption and CO2 emissions as a result of energy efficiency improvements in Swedish manufacturing industries between 1993 and 2008. Using data at the two-digit level, the performance of this sector is studied in terms of CO2 emissions, energy consumption, energy efficiency measured as energy intensity, value of production, fuel sources, energy prices and energy taxes. It was found that energy consumption, energy intensity and CO2 emission intensity, measured as production values, have decreased significantly in the Swedish manufacturing industries during the period studied. The results of the decomposition analysis show that output growth has not required higher energy consumption, leading to a reduction in both energy and CO2 emission intensities. The role of structural changes has been minor, and the trends of energy efficiency and CO2 emissions have been similar during the sample period. A stochastic frontier model was used to determine possible factors that may have influenced these trends. The results demonstrate that high energy prices, energy taxes, investments and electricity consumption have influenced the reduction of energy and CO2 emission intensities, indicating that Sweden has applied an adequate and effective energy policy. The study confirms that it is possible to achieve economic growth and sustainable development whilst also reducing the pressure on resources and energy consumption and promoting the shift towards a low-carbon economy.

    Industry accounts for about one-third of global energy demand. Most of that energy is used to produce raw materials: chemicals, iron and steel, non-metallic minerals, pulp and paper and non-ferrous metals. Just how efficiently is this energy put to work? This question was on the minds of the G8 leaders at their summit in Gleneagles in 2005, when they set a 'Plan of Action for Climate Change, Clean Energy and Sustainable Development'. They called upon the International Energy Agency to provide information and advice in a number of areas including special attention to the industrial sector. Tracking Industrial Energy Efficiency and CO2 Emissions responds to the G8 request. This major new analysis shows how industrial energy efficiency has improved dramatically over the last 25 years. Yet important opportunities for additional gains remain, which is evident when the efficiencies of different countries are compared. This analysis identifies the leaders and the laggards. It explains clearly a complex issue for non-experts. With new statistics, groundbreaking methodologies, thorough analysis and advice, and substantial industry consultation, this publication equips decision makers in the public and private sectors with the essential information that is needed to reshape energy use in manufacturing in a more sustainable manner.

    The U.S. baking industry consumes more than 82 trillion BTU/yr or 7% of the gross energy used by the U.S. food system. In order to establish energy saving possibilities in the baking industry, energy audits were performed for 5 bakery plants. These audits resulted in suggestions for formal programs for energy conservation and involve changes in operating procedures, equipment improvement, increased thermal insulation in buildings and equipment, recovery of waste heat, and the substitution of fossil fuel for higher cost electric power for heating. The economic advantages of such modifications are given. (LCL)

    Past energy-consumption trends and future energy-conservation opportunities are investigated for the nation's iron and steel industry. It is estimated that, in 1980, the industry directly consumed approximately 2.46 x 10/sup 15/ Btu of energy (roughly 3% of total US energy consumption) to produce 111 million tons of raw steel and to ship 84 million tons of steel products. Direct plus indirect consumption is estimated to be about 3.1 x 10/sup 15/ Btu. Of the set of conservation technologies identified, most are judged to be ready for commercialization if and when the industry's capital formation and profitability problems are solved and the gradual predicted increase in energy prices reduces the payback periods to acceptable levels.

    If dark energy, which drives the accelerated expansion of the universe, consists of a light scalar field, it might be detectable as a "fifth force" between normal-matter objects, in potential conflict with precision tests of gravity. Chameleon fields and other theories with screening mechanisms, however, can evade these tests by suppressing the forces in regions of high density, such as the laboratory. Using a cesium matter-wave interferometer near a spherical mass in an ultrahigh-vacuum chamber, we reduced the screening mechanism by probing the field with individual atoms rather than with bulk matter. We thereby constrained a wide class of dark energy theories, including a range of chameleon and other theories that reproduce the observed cosmic acceleration.

    We analyze the ground state energy of helium atom confined by spherical impenetrable walls, and the role of the correlation energy in the total energy. The confinement of an atom in a cavity is one way in which we can model the effect of the external pressure on an atom. The calculations of energy of the system are carried out by the variational method. We find that the correlation energy remains almost constant for a range values of size of the boxes analyzed.

    The Bonneville Power Administration (Bonneville) has identified 101 plants in the Pacific Northwest that account for 80% of the region's industrial electricity consumption. These plants offer a precise target for a conservation program. PNL determined that most of these 101 plants were represented by 11 major industries. We then reviewed 36 major conservation technologies used in these 11 industrial settings to determine their potential environmental impacts. Energy efficiency technologies designed for industrial use may result in direct or indirect environmental impacts. Effects may result from the production of the conservation measure technology, changes in the working environment due to different energy and material requirements, or changes to waste streams. Industry type, work-place conditions, worker training, and environmental conditions inside and outside the plant are all key variables that may affect environmental outcomes. To address these issues this report has three objectives: Describe potential conservation measures that Bonneville may employ in industrial programs and discuss potential primary impacts. Characterize industrial systems and processes where the measure may be employed and describe general environmental issues associated with each industry type. Review environmental permitting, licensing, and other regulatory actions required for industries and summarize the type of information available from these sources for further analysis.

  9. Atomic-powered democracy: Policy against politics in the quest for American nuclear energy

    Energy Technology Data Exchange (ETDEWEB)

    Williams, R.W.

    1993-01-01

    This dissertation focuses on the relationship of American nuclear energy to democracy. It examines whether the nuclear policy processes have furthered the legitimacy-government accountability and citizen participation-which the democratic institutes are based. Nuclear policy and its institutions have placed severe limitations on democratic practices. Contravened democracy is seen most clearly in the decoupling of policy from politics. Decoupling refers to the weakening of institutional linkages between citizens and government, and to the erosion of the norms that ground liberal democracy. Decoupling is manifested in policy centralization, procedural biases, technical rationality, and the spatial displacement of conflict. Decoupling has normative implications: While federal accountability was limited and citizen participation was shackled, other major groups enjoyed privileged access to policy making. The decoupling of nuclear policy from politics arose within the context of US liberal-democratic capitalism. The federal government pursued its own goals of defense and world leadership. Yet, it was not structurally autonomous from the hegemony of the political-economic context. Economically, the Atomic Energy Act did not permit federal agencies to directly invest in power plant construction, and did not authorize them to commercially generate electricity. Private industry was structurally placed to domesticate the atom. Politically, the liberal-democratic system hampered an unquestioning pursuit of atomic energy. Federal institutions have been forced to heed some of the anti-nuclear concerns. The pervasive influence of the US political economy on nuclear policy has come to transgress democracy. Nuclear power's growth faltered during the 1970s. The political and economic constraints on federal actions have limited the means available to revive a becalmed nuclear industry; this has exerted strong pressure on federal institutions to decouple policy from

    2016-04-01

    Full Text Available The gas engine driven carbon dioxide heat pump designed for providing the heat, cold and electricity for industrial poultry house is proposed. The scheme differs from the known by using recuperative heat exchanger installed between the exhaust air duct of poultry house and heat pump evaporator and the heat curtain installed on the air duct after the evaporator. The air coming into the poultry house after the regenerative heat exchanger is supplied to the heat pump gas cooler. The heat pump produces heat of the required parameters of the input air and water for watering of poultry, space heating, etc. Heat pump compressor is driven by gas engine (GPA, by natural gas or biogas. The part of the gas-piston engine heat is used for adjusting the optimal heat pump mode and for regeneration of the absorbent in an evaporative cooler. The proposed technical solution of the above scheme provides a higher COP of the heat pump. Installing of heat curtain does not require the use of non-freezing solution to prevent icing of the air outlet of heat pump evaporator. The latter allows producing, besides electric power and heat, still cold (with the use off the adsorption-refrigerating machine and provide drying air inlet evaporative cooler (if necessary.

    Isotope effects for charge transfer processes have recently received increased attention. The ion-atom merged-beams apparatus at Oak Ridge National Laboratory is used to measure charge transfer for low energy collisions of multi-charged ions with H and D and is therefore well suited to investigate isotope effects. The apparatus has been relocated and upgraded to accept high velocity beams from the 250 kV High Voltage Platform at the Multi-Charged Ion Research Facility. The intense higher velocity multi-charged ion beams allow, for the first time, measurements with both H and D from keV/u down to meV/u collision energies in the center-of-mass frame. When charge transfer occurs at relatively large inter-nuclear distances (via radial couplings) the ion-induced dipole attraction can lead to trajectory effects, causing differences in the charge transfer cross sections for H and D. A strong isotope effect (nearly a factor of two) has been observed in the cross section for Si4+ + H(D) below 0.1 eV/u. However, little or no difference is observed for N2+ + H(D). Recently, strong effects have been predicted for the fundamental system He2+ + H(D,T) at collision energies below 200 eV/u where charge transfer occurs primarily through united-atom rotational coupling. We are currently exploring systems where rotational coupling is important and isotopic differences in the cross section can be observed.

    Guidance is given on measuring energy consumption in the plant and pinpointing areas where energy-conservation activities can return the most favorable economics. General energy-conservation techniques applicable to most or all segments of the dairy processing industry, including the fluid milk segment, are emphasized. These general techniques include waste heat recovery, improvements in electric motor efficiency, added insulation, refrigeration improvements, upgrading of evaporators, and increases in boiler efficiency. Specific examples are given in which these techniques are applied to dairy processing plants. The potential for energy savings by cogeneration of process steam and electricity in the dairy industry is also discussed. Process changes primarily applicable to specific milk products which have resulted in significant energy cost savings at some facilities or which promise significant contributions in the future are examined. A summary checklist of plant housekeeping measures for energy conservation and guidelines for economic evaluation of conservation alternatives are provided. (MHR)

    The Energy Conservation Projects to benefit the railroad industry using the Norfolk Southern Company as a model for the railroad industry has five unique tasks which are in areas of importance within the rail industry, and specifically in the area of energy conservation. The NIU Engineering and Technology research team looked at five significant areas in which research and development work can provide unique solutions to the railroad industry in energy the conservation. (1) Alternate Fuels - An examination of various blends of bio-based diesel fuels for the railroad industry, using Norfolk Southern as a model for the industry. The team determined that bio-diesel fuel is a suitable alternative to using straight diesel fuel, however, the cost and availability across the country varies to a great extent. (2) Utilization of fuel cells for locomotive power systems - While the application of the fuel cell has been successfully demonstrated in the passenger car, this is a very advanced topic for the railroad industry. There are many safety and power issues that the research team examined. (3) Thermal and emission reduction for current large scale diesel engines - The current locomotive system generates large amount of heat through engine cooling and heat dissipation when the traction motors are used to decelerate the train. The research team evaluated thermal management systems to efficiently deal with large thermal loads developed by the operating engines. (4) Use of Composite and Exotic Replacement Materials - Research team redesigned various components using new materials, coatings, and processes to provide the needed protection. Through design, analysis, and testing, new parts that can withstand the hostile environments were developed. (5) Tribology Applications - Identification of tribology issues in the Railroad industry which play a significant role in the improvement of energy usage.

    Research on electrochemical energy storage devices including Li ion batteries (LIBs), Na ion batteries (NIBs) and supercapacitors (SCs) has accelerated in recent years, in part because developments in nanomaterials are making it possible to achieve high capacities and energy and power densities. These developments can extend battery life in portable devices, and open new markets such as electric vehicles and large-scale grid energy storage. It is well known that surface reactions largely determine the performance and stability of electrochemical energy storage devices. Despite showing impressive capacities and high energy and power densities, many of the new nanostructured electrode materials suffer from limited lifetime due to severe electrode interaction with electrolytes or due to large volume changes. Hence control of the surface of the electrode material is essential for both increasing capacity and improving cyclic stability of the energy storage devices.Atomic layer deposition (ALD) which has become a pervasive synthesis method in the microelectronics industry, has recently emerged as a promising process for electrochemical energy storage. ALD boasts excellent conformality, atomic scale thickness control, and uniformity over large areas. Since ALD is based on self-limiting surface reactions, complex shapes and nanostructures can be coated with excellent uniformity, and most processes can be done below 200. °C. In this article, we review recent studies on the use of ALD coatings to improve the performance of electrochemical energy storage devices, with particular emphasis on the studies that have provided mechanistic insight into the role of ALD in improving device performance. © 2016 Elsevier Ltd.

  19. Energy and materials flows in the copper industry

    1980-12-01

    The copper industry comprises both the primary copper industry, which produces 99.9%-pure copper from copper ore, and the secondary copper industry, which salvages and recycles copper-containing scrap metal to extract pure copper or copper alloys. The United States uses about 2 million tons of copper annually, 60% of it for electrical applications. Demand is expected to increase less than 4% annually for the next 20 years. The primary copper industry is concentrated in the Southwest; Arizona produced 66% of the 1979 total ore output. Primary production uses about 170 x 10/sup 12/ Btu total energy annually (about 100 x 10/sup 6/ Btu/ton pure copper produced from ore). Mining and milling use about 60% of the total consumption, because low-grade ore (0.6% copper) is now being mined. Most copper is extracted by smelting sulfide ores, with concomitant production of sulfur dioxide. Clean air regulations will require smelters to reduce sulfur emissions, necessitating smelting process modifications that could also save 20 x 10/sup 12/ Btu (10 x 10/sup 6/ Btu/ton of copper) in smelting energy. Energy use in secondary copper production averages 20 x 10/sup 6/ Btu/ton of copper. If all copper products were recycled, instead of the 30% now salvaged, the energy conservation potential would be about one-half the total energy consumption of the primary copper industry.

    Ontario's $3.3 billion baking industry includes 459 companies with 20,000 employees. Although the industry relies on grain and other raw materials, the location and geographic market potential has been broadened by the use of refrigeration technology. The cost of refrigeration and baking has rendered bakeries energy intensive, requiring gas for baking and electricity for freezers. The rising energy costs are becoming a major portion of the ingredient costs of baked goods. The Ontario Food Industry Cost Reduction Program was prepared to help the food industry reduce their energy, water and sewer costs. This paper describes the participation of Oakrun Farm Bakery in an Industrial Energy Efficiency Audit in the winter of 2001. The audit revealed that the bakery has the potential to reduce natural gas consumption by 17 per cent and reduce electricity consumption by 13 per cent for a potential reduction in greenhouse gas emissions of 800 tonnes per year. The audit identified 4 energy saving opportunities for the refrigeration system: reduce compressor discharge; increase suction pressure; install an evaporative condenser; and, install electronic temperature controls. The company plans to implement the opportunities on a prioritized basis in 2003 following an expansion to the plant. 1 tab., 2 figs.

    The detection of energetic neutral atoms allows for the remote examination of the interactions between plasmas and neutral populations in space. Before these neutral atoms can be measured, they must first be converted to ions. For the low energy end of this spectrum, interaction with a conversion surface is often the most efficient method to convert neutrals into ions. It is generally thought that the most efficient surfaces are low work functions materials. However, by their very nature, these surfaces are highly reactive and unstable, and therefore are not suitable for space missions where conditions cannot be controlled as they are in a laboratory. We therefore are looking to optimize a stable surface for conversion efficiency. Conversion efficiency can be increased either by changing the incident angle of the neutral particles to be grazing incidence and using stable surfaces with high conversion efficiencies. We have examined how to increase the angle of incidence from -80 degrees to -89 degrees, while maintaining or improving the total active conversion surface area without increasing the overall volume of the instrument. We are developing a method to micro-machine silicon, which will reduce the volume to surface area ratio by a factor of 60. We have also examined the material properties that affect the conversion efficiency of the surface for stable surfaces. Some of the parameters we have examined are work function, smoothness, and bond structure. We find that for stable surfaces, the most important property is the smoothness of the surface.

    The purpose of this report is to establish the content and structural validity of the Long-term Industrial Energy Forecasting (LIEF) model, and to provide estimates for the model`s parameters. The model is intended to provide decision makers with a relatively simple, yet credible tool to forecast the impacts of policies which affect long-term energy demand in the manufacturing sector. Particular strengths of this model are its relative simplicity which facilitates both ease of use and understanding of results, and the inclusion of relevant causal relationships which provide useful policy handles. The modeling approach of LIEF is intermediate between top-down econometric modeling and bottom-up technology models. It relies on the following simple concept, that trends in aggregate energy demand are dependent upon the factors: (1) trends in total production; (2) sectoral or structural shift, that is, changes in the mix of industrial output from energy-intensive to energy non-intensive sectors; and (3) changes in real energy intensity due to technical change and energy-price effects as measured by the amount of energy used per unit of manufacturing output (KBtu per constant $ of output). The manufacturing sector is first disaggregated according to their historic output growth rates, energy intensities and recycling opportunities. Exogenous, macroeconomic forecasts of individual subsector growth rates and energy prices can then be combined with endogenous forecasts of real energy intensity trends to yield forecasts of overall energy demand. 75 refs.

  6. Energy conservation in industry: Technical feasibility and obstacles

    A comparison of Italy's energy requirements with those of other industrialized countries reveals that, while this nation does not have a particularly burdensome energy demand, it is strongly dependent on foreign energy supplies, and thus must have recourse to energy conservation. This analysis of energy demand and energy conservation in Italy focusses on industrial trends witnessed over the last decade. Here, it is noted that energy conservation received attention early in the 1980's as energy prices increased - a trend which died, however, with this current span of relatively stable prices. Noted obstacles to vigorous energy conservation include: a strong tendency towards the use of conventional, proven technologies; difficulties in evaluating the benefits of innovative energy savings equipment alternatives due to oil price uncertainty; and the pronounced lack of sufficiently well trained energy managers. On the technical side, sound energy savings systems are coming on the market, e.g., heat pumps, cogeneration systems, etc., but marketing efforts for these products have yet to incorporate effective programs for information dissemination and operator training.

    A highly excited (n 306) quasi one-dimensional Rydberg atom exposed to periodic alternating external electric field pulses exhibits chaotic behavior. Time evolution of this system is governed by a geometric structure of phase space called a homoclinic tangle and its turnstile. The turnstile is responsible for organizing chaotic ionization. We present and explain the results from an experiment designed to probe the structure of the phase space turnstile. We create time-independent Rydberg wave packets, subject them to alternating electric field kicks, and measure the ionization fraction. We present the behavior of the ionization fraction as a function of the applied kick strength and show that this behavior is directly connected to the size and shape of the underlying turnstile. For short kicking periods the ionization fraction as a function of the applied kick strength exhibits step-function-like behavior that changes into s-shape behavior for large kicking periods. Next we use the geometric structure of phase space to design a short pulse sequence that quickly and efficiently transfers electronic wave packet from a high energy state to a much lower energy state. Finally, we show how the phase space geometry influences the efficiency of the transport between energy states.

    2015-01-01

    The available energy resources are being depleted worldwide. Industrial symbiosis (IS) provides a promising approach for increasing the efficiency of energy utilization, with numerous studies reporting the superiority of this technology. However, studies quantifying the energy-saving efficiency of IS remain insufficient. This paper proposes an index system for the quantitative evaluation of the energy-saving efficiency of IS. Both energy-saving and financial indexes were selected, the former include the IS energy-saving index, the contribution rate of energy saved through IS, fractional energy savings, and cut rate of energy consumption per total output value; and the latter include the IS investment payback period, IS input-output ratio, net present value (NPV), and internal rate of return (IRR) of IS. The proposed methods were applied to a case study on the XF Industrial Park (XF IP), in the city of Liaocheng in Shandong Province of China. Three energy-saving channels using IS were found in the XF IP: (a) utilizing the energy of high-temperature materials among industrial processes, (b) recovering waste heat and steam between different processes, and (c) saving energy by sharing infrastructures. The results showed that the energy efficiency index of IS was 0.326, accounting for 34.6% of the comprehensive energy-saving index in 2011, and the fractional energy-savings were 12.42%. The index of energy consumption per total industrial output value varied from 90.9 tce/MRMB to 51.6 tce/MRMB. Thus, the cut rate of energy consumption per total industrial output value was 43.42%. The average values of the IS input-output ratio was 406.2 RMB/tce, 57.2% lower than the price of standard coal. Static investment payback period in the XF IP was 8.5 months, indicating that the XF IP began to earn profit 8.5 months after the construction of all IS modes. The NVP and IRR of each IS mode in the XF IP were greater than zero, with average values equal to 1,789.96 MRMB and 140

    United States energy policies aim at cutting down dependence on foreign oil in two ways: by energy conservation and by finding new domestic supplies. The study investigates how the first goal can be achieved in the industrial sector (manufacturing) of the economy, which accounts for about 40% (about 7.3 million barrels per day) of the total energy consumption in the US. It is noted that industry is able to conserve as much as 25 to 30% of its energy consumption by adopting simple conservation measures and energy-efficient technologies. These technologies can be implemented without major alterations of the original equipment. The schools of thought on innovative processes are discussed; these will serve as the conceptual and methodological base of the project. (MCW)

    This publication further develops the analysis presented in the India chapter of Energy Technology Perspectives 2010 and provides insights on the implications of achieving deep energy and CO2 emission cuts in the industrial sector both for India and globally. It investigates the least-cost combination of options that can significantly reduce energy and CO2 emissions in India's industrial sector, while enabling the Indian economy to continue to grow and alleviate energy poverty. For India to play its part in helping to realise deep cuts in global CO2 emissions by the middle of the 21st century, it will need to achieve rapid economic development over the next 40 years with only a very small increase in emissions. Currently there is no precedent for such a low-CO2 development path. The challenge for India will be to achieve strong economic growth while improving energy security, but without locking in high emissions.

    2005-07-01

    This paper reviewed human resources issues related to wind energy expansion. As the fastest growing energy source in the world, wind energy has the potential to provide thousands of jobs. With the signing of the Kyoto Protocol, the Canadian government and industry will take measures to increase the use of renewable energy. As such, forecasters predict that Canada's total installed capacity will increase from 444 MW in 2004 to 5,600 MW by 2012. Initially, employment opportunities will be in the service industry, followed by an increased demand for scientists, engineers, technicians and other personnel with specialized knowledge in the wind industry. This paper described the assumptions on which the forecasted demand for skilled labour is based. Approximately 2,230 technicians will be required by 2012 to develop and manufacture wind turbines and to establish an infrastructure that would maximize the benefits of the emerging industry for Canadians. Wind energy initiatives include the establishment of a competitive manufacturing and service base; the provision of specialized training and education to meet the human resources demands of the industry; and, support from research and development to reduce the knowledge gap between Canada and Europe. Canada also holds the potential to establish a niche market for hybrid wind-diesel-storage systems. Insurance companies and investors will require high standards to safeguard their investments. A breakdown of various jobs in the wind power industry was presented along with forecasts of revenues and employment in Canada's wind energy industry. This paper also outlined the wind energy research programs available at Canadian universities, colleges and institutes. It was recommended that education and training programs in this field of study should be developed based on proven programs with a governing body to ensure industry requirements are met. It was also suggested that partnerships should be formed with successful

    The potential is examined for waste heat recovery and reuse through thermal energy storage in five specific industrial categories: (1) primary aluminum, (2) cement, (3) food processing, (4) paper and pulp, and (5) iron and steel. Preliminary results from Phase 1 feasibility studies suggest energy savings through fossil fuel displacement approaching 0.1 quad/yr in the 1985 period. Early implementation of recovery technologies with minimal development appears likely in the food processing and paper and pulp industries; development of the other three categories, though equally desirable, will probably require a greater investment in time and dollars.

    In order to characterize industrial energy service, current energy demand, its end uses, and cost of typical energy applications and resultant services in the industrial sector were examined and a projection of state industrial energy demands and prices to 1990 was developed. Volume II presents in Section 2 data on the US manufacturing subsector energy demand, intensity, growth rates, and cost for 1971, 1974, and 1976. These energy data are disaggregated not only by fuel type but also by user classifications, including the 2-digit SIC industry groups, 3-digit subgroups, and 4-digit SIC individual industries. These data characterize typical energy applications and the resultant services in this subsector. The quantities of fuel and electric energy purchased by the US manufacturing subsector were converted to British thermal units and reported in billions of Btu. The conversion factors are presented in Table 4-1 of Volume I. To facilitate the descriptive analysis, all energy cost and intensity data were expressed in constant 1976 dollars. The specific US industrial energy service characteristics developed and used in the descriptive analysis are presented in Volume I. Section 3 presents the computer program used to produce the tabulated data.

    The dose management system (DMS) is a computer software developed by the International Atomic Energy Agency for managing data on occupational exposure to radiation sources and intake of radionuclides. It is an integrated system for the user-friendly storage, processing and control of all existing internal and external dosimetry data. The Radiation Protection Board (RPB) of the Ghana Atomic Energy Commission has installed, customised, tested and using the DMS as a comprehensive DMS to improve personnel and area monitoring in the country. Personnel dose records from the RPBs database from 2000 to 2009 are grouped into medical, industrial and education/research sectors. The medical sector dominated the list of monitored institutions in the country over the 10-y period representing ∼87 %, while the industrial and education/research sectors represent ∼9 and ∼4 %, respectively. The number of monitored personnel in the same period follows a similar trend with medical, industrial and education/research sectors representing ∼74, ∼17 and ∼9 %, respectively. Analysis of dose data for 2009 showed that there was no instance of a dose above the annual dose limit of 20 mSv, however, 2.7 % of the exposed workers received individual annual doses >1 mSv. The highest recorded individual annual dose and total collective dose in all sectors were 4.73 mSv and 159.84 man Sv, respectively. Workers in the medical sector received higher individual doses than in the other two sectors, and average dose per exposed worker in all sectors is 0.25 mSv.

    Love, P. [Canadian Energy Efficiency Alliance (Canada)

    2003-07-01

    Energy conservation, energy efficiency and demand side management are defined and the role played in the promotion and advancement of energy efficiency objectives by the Canadian Energy Efficiency Alliance are explained. Direct and indirect economic and environmental benefits and the potential impacts in terms of savings and jobs are discussed, with examples of successful greenhouse gas emission reduction programs by industry. The total potential for energy efficiency in Canada is estimated at 18 per cent lower energy use by 2010, and 33 per cent by 2020, assuming that specific policy recommendations and other cost effective efficiency measures are implemented. Overall conclusions are that there is a large potential for cost-effective energy savings over and above of what has been done already. Furthermore, utilities can play a leading role in realizing these efficiencies, and in the process achieve substantial benefits for themselves.

    1991-03-01

    Since 1989, the U.S. Department of Energy has sponsored the Energy Efficient Industrialized Housing research program (EEIH) to improve the energy efficiency of industrialized housing. Two research centers share responsibility for this program: The Center for Housing Innovation at the University of Oregon and the Florida Solar Energy Center, a research institute of the University of Central Florida. Additional funding is provided through the participation of private industry, state governments and utilities. The program is guided by a steering committee comprised of industry and government representatives. This report summarizes Fiscal Year (FY) 1990 activities and progress, and proposed activities for FY 1991 in Task 2.1 Design for Energy Efficiency. This task establishes a vision of energy conservation opportunities in critical regions, market segments, climate zones and manufacturing strategies significant to industrialized housing in the 21st Century. In early FY 1990, four problem statements were developed to define future housing demand scenarios inclusive of issues of energy efficiency, housing design and manufacturing. Literature surveys were completed to assess seven areas of influence for industrialized housing and energy conservation in the future. Fifty-five future trends were identified in computing and design process; manufacturing process; construction materials, components and systems; energy and environment; demographic context; economic context; and planning policy and regulatory context.

  9. Potential for energy conservation in the cement industry

    Energy Technology Data Exchange (ETDEWEB)

    Garrett-Price, B.A.

    1985-02-01

    This report assesses the potential for energy conservation in the cement industry. Energy consumption per ton of cement decreased 20% between 1972 and 1982. During this same period, the cement industry became heavily dependent on coal and coke as its primary fuel source. Although the energy consumed per ton of cement has declined markedly in the past ten years, the industry still uses more than three and a half times the fuel that is theoretically required to produce a ton of clinker. Improving kiln thermal efficiency offers the greatest opportunity for saving fuel. Improving the efficiency of finish grinding offers the greatest potential for reducing electricity use. Technologies are currently available to the cement industry to reduce its average fuel consumption per ton by product by as much as 40% and its electricity consumption per ton by about 10%. The major impediment to adopting these technologies is the cement industry's lack of capital as a result of low or no profits in recent years.

  10. Utilization of waste heat from energy conversion and industrial processes

    Evans, A.R.; Hamilton, R.W.

    The laws of thermodynamics state that no process of energy transformation can take place with perfect efficiency--some waste heat is always produced. The generation of waste heat from energy conversion and industrial processes are discussed. First-law and second-law efficiencies are defined. After listing the amounts of waste heat produced, some technological options for reducing waste heat or using it for other purposes, such as district heating, are described.

  11. The evolution of nuclear energy Opportunities for the industry

    Energy Technology Data Exchange (ETDEWEB)

    Dominguez, M. T.

    2013-10-01

    At the turn of the XXI century, the world energy context underwent a significant change due mainly to the increases in the demand for energy in the developing countries, a rise in gas prices and increased government support of clean energies in response to environmental issues. these boundary conditions led rapidly to renewed interest in nuclear energy worldwide. The phrase a Renaissance in nuclear energy was included in almost all energy forecasts. Unexpectedly, however, just then years later the panorama changed once again: unconventional gas appeared as new energy source, the world financial crisis hampered investment, and the demand for energy fell. This panorama has lowered expectations with regard to the size of the nuclear energy renaissance to a less buoyant but more balance scenario of nuclear energy deployment that we could now dub as the evolution of nuclear energy. This article describes how fission nuclear energy has continuously been evolving to adjust itself to these changing scenarios, and, in particular, how it is being adapted itself to todays vision of the role of the nuclear energy in the long term. The analysis in this paper focuses on those programs that could bring opportunities for Spanish nuclear industry participation. Starting with the development programs affecting existing reactors already in operation, the analysis moves on the new builds of Light Water Reactors (LWR) Generation III+, to then address, in two sections, Research Reactors and finally, the opportunities presented by Generation IV technologies. The development of fusion technology is not covered in this paper. (Author)

  14. Energy requirements of the U. S. pulp and paper industry

    Energy Technology Data Exchange (ETDEWEB)

    Cosman, C.M.

    1979-01-01

    According to the American Paper Institute, the paper industry is the fifth largest consumer of purchased energy in the U.S. and the largest consumer of fuel oil. Almost one-half of its total energy consumption comes from the industry's own process wasts: spent pulping liquors, bark, and hogged wood. In 1976 non-fossil fuels provided 44.6% of the total Btu consumption, up from 41.1% in 1972 and 42.6% in 1975. (Self-generated hydro power and other electricity produced from fossil fuel supplied another 1.5% of total needs in 1972 and 2.1% in 1975.) The industry has established a mechanism for self-policing by submitting periodic reports on its energy consumption to the API. The target set by the industry is a 20% saving of purchased energy by 1980. So far a reduction of about 15% has been achieved, making adjustments for add-ons required because of environmental regulations and other changes vs the base year of 1972.

    2013-01-01

    The course, technical progresses, and achievements of energy conservation of China steel industry (CSI) during 1980-2010 were summarized. Then, the paper adopted e-p method to analyze the variation law and influencing factors of energy consumptions of large- and medium-scale steel plants within different stages. It is pointed out that energy consumption per ton of crude steel has been almost one half lower in these thirty years, with 60% as direct energy conservation owing to the change of process energy consumption and 40% as indirect energy conservation attributed to the adjustment of production structure. Next, the latest research progress of some key common technologies in CSI was introduced. Also, the downtrend of energy consumption per ton of crude steel and the potential energy conservation for CSI during 2011-2025 were forecasted. Finally, it is indicated that the key topic of the next 15 years' research on the energy conservation of CSI is the synergistic operation of material flow and energy flow. It could be achieved by the comprehensive study on energy flow network optimization, such as production, allocation, utilization, recovery, reuse, and resource, according to the energy quantity, quality, and user demand following the first and second laws of thermodynamics.

    2015-11-06

    Since 1976, the Industrial Assessment Centers (IACs), administered by the US Department of Energy, have supported small and medium-sized American manufacturers to reduce energy use and increase their productivity and competitiveness. The 24 IACs, located at premier engineering universities around the country (see below), send faculty and engineering students to local small and medium-sized manufacturers to provide no-cost assessments of energy use, process performance and waste and water flows. Under the direction of experienced professors, IAC engineering students analyze the manufacturer’s facilities, energy bills and energy, waste and water systems, including compressed air, motors/pumps, lighting, process heat and steam. The IACs then follow up with written energy-saving and productivity improvement recommendations, with estimates of related costs and payback periods.

  1. Energy use in the biscuit-baking industry

    Energy Technology Data Exchange (ETDEWEB)

    Cleland, A.C.; Earle, M.D.

    1980-05-01

    A survey was carried out to ascertain the level of energy use in the New Zealand biscuit baking industry. All firms in the New Zealand food processing industry that produce biscuits were sent a questionnaire requesting information on energy consumption and production. Replies were received from five factories and the information from these was supplemented by detailed factory surveys in two other factories. Measures to reduce energy consumption are proposed. Replacement of existing steam boilers with boilers better suited to provide the requirements for process steam would lead to significant reductions in baseload boiler fuel use. Small savings both in boiler fuel consumption and oven fuel consumption can be made by improvements to insulation. Further savings in oven fuel consumption are unlikely except by replacement of the existing ovens with more energy-conscious designs. The design of the biscuit coolers used in the industry can be improved to reduce the electricity consumed by the refrigeration equipment for these coolers. Process flow charts are presented. An analysis of energy consumption was made. (MCW)

    Assumptions regarding the magnitude and direction ofenergy-related technological change have long beenrecognized as criticaldeterminants of the outputs and policy conclusions derived fromintegrated assessment models. Particularly in the case of developingcountries, however, empirical analysis of technological change has laggedbehind simulation modeling. This paper presents estimates of sectoralproductivity trends and energy-augmenting technological change forseveral energy-intensive industries in India and South Korea, and, forcomparison, the United States. The key findings are substantialheterogeneity among both industries and countries, and a number of casesof declining energy efficiency. The results are subject to certaintechnical qualifications both in regards to the methodology and to thedirect comparison to integrated assessment parameterizations.Nevertheless, they highlight the importance of closer attention to theempirical basis for common modeling assumptions.

    1994-06-23

    This report traces key financial trends in the US energy industry for the first quarter of 1994. Financial data (only available for publicly-traded US companies) are included in two broad groups -- fossil fuel production and rate-regulated electric utilities. All financial data are taken from public sources such as energy industry corporate reports and press releases, energy trade publications, and The Wall Street Journal`s, Earnings Digest. Return on equity is calculated from data available from Standard and Poor`s Compustat data service. Since several major petroleum companies disclose their income by lines of business and geographic area. These data are also presented in this report. Although the disaggregated income concept varies by company and is not strictly comparable to corporate income, relative movements in income by lines of business and geographic area are summarized as useful indicators of short-term changes in the underlying profitability of these operations.

  4. US energy industry financial developments, 1993 first quarter

    Energy Technology Data Exchange (ETDEWEB)

    1993-06-25

    Net income for 259 energy companies-- including, 20 major US petroleum companies-- rose 38 percent between the first quarter of 1992 and the first quarter of 1993. An increased level of economic activity, along with colder weather, helped lift the demand for natural gas. crude oil, coal, and electricity. The sharp rise in the domestic price of natural gas at the wellhead relative to the year-ago quarter was the most significant development in US energy during the first quarter. As a consequence of higher natural gas prices, the upstream segment of the petroleum industry reported large gains in income, while downstream income rose due to higher refined product demand. Increased economic activity and higher weather-related natural gas demand also led to improvements in income for the rate-regulated energy segment. However, declining domestic oil production continued to restrain upstream petroleum industry earnings growth, despite a moderate rise in crude oil prices.

    2000-04-01

    The U.S. chemical industry is the largest in the world, and responsible for about 11% of the U.S. industrial production measured as value added. It consumes approximately 20% of total industrial energy consumption in the U.S. (1994), and contributes in similar proportions to U.S. greenhouse gas emissions. Surprisingly, there is not much information on energy use and energy intensity in the chemical industry available in the public domain. This report provides detailed information on energy use and energy intensity for the major groups of energy-intensive chemical products. Ethylene production is the major product in terms of production volume of the petrochemical industry. The petrochemical industry (SIC 2869) produces a wide variety of products. However, most energy is used for a small number of intermediate compounds, of which ethylene is the most important one. Based on a detailed assessment we estimate fuel use for ethylene manufacture at 520 PJ (LHV), excluding feedstock use. Energy intensity is estimated at 26 GJ/tonne ethylene (LHV), excluding feedstocks.The nitrogenous fertilizer production is a very energy intensive industry, producing a variety of fertilizers and other nitrogen-compounds. Ammonia is the most important intermediate chemical compound, used as basis for almost all products. Fuel use is estimated at 268 PJ (excluding feedstocks) while 368 PJ natural gas is used as feedstock. Electricity consumption is estimated at 14 PJ. We estimate the energy intensity of ammonia manufacture at 39.3 GJ/tonne (including feedstocks, HHV) and 140 kWh/tonne, resulting in a specific primary energy consumption of 40.9 GJ/tonne (HHV), equivalent to 37.1 GJ/tonne (LHV). Excluding natural gas use for feedstocks the primary energy consumption is estimated at 16.7 GJ/tonne (LHV). The third most important product from an energy perspective is the production of chlorine and caustic soda. Chlorine is produced through electrolysis of a salt-solution. Chlorine production is

    2016-07-07

    The fabrication of porous nanocomposites is key to the advancement of energy conversion and storage devices that interface with electrolytes. Bismuth vanadate, BiVO4 , is a promising oxide for solar water splitting where the controlled fabrication of BiVO4 layers within porous, conducting scaffolds has remained a challenge. Here, the atomic layer deposition of bismuth vanadates is reported from BiPh3 , vanadium(V) oxytriisopropoxide, and water. The resulting films have tunable stoichiometry and may be crystallized to form the photoactive scheelite structure of BiVO4 . A selective etching process was used with vanadium-rich depositions to enable the synthesis of phase-pure BiVO4 after spinodal decomposition. BiVO4 thin films were measured for photoelectrochemical performance under AM 1.5 illumination. The average photocurrents were 1.17 mA cm(-2) at 1.23 V versus the reversible hydrogen electrode using a hole-scavenging sulfite electrolyte. The capability to deposit conformal bismuth vanadates will enable a new generation of nanocomposite architectures for solar water splitting.

    Canada has been a leader in tritium handling technologies as a result of the successful CANDU reactor technology used for power production. Over the last 50 to 60 years, capabilities have been established in tritium handling and tritium management in CANDU stations, tritium removal processes for heavy and light water, tritium measurement and monitoring, and understanding the effects of tritium on the environment. This paper outlines details of tritium-related work currently being carried out at Atomic Energy of Canada Limited (AECL). It concerns the CECE (Combined Electrolysis and Catalytic Exchange) process for detritiation, tritium-compatible electrolysers, tritium permeation studies, and tritium powered batteries. It is worth noting that AECL offers a Tritium Safe-Handling Course to national and international participants, the course is a mixture of classroom sessions and hands-on practical exercises. The expertise and facilities available at AECL is ready to address technological needs of nuclear fusion and next-generation nuclear fission reactors related to tritium handling and related issues.

    The United States railroad industry plays a key role in transporting materials to support our industrial economy. One of the oldest industries in the US, the railroads have developed over 150 years into their present physical and operational configuration. Energy conservation proposals to change industry facilities, equipment, or operating practices must be evaluated in terms of their cost impact. A current, comprehensive and accurate data baseline of railroad economic activity and energy consumption is presented. Descriptions of the history of railroad construction in the US and current equipment, facilities, and operation practices follow. Economic models that relate cost and energy of railroad service to the volume of railroad output and to physical and operational parameters are provided. The analyses and descriptions should provide not only an analytical baseline for evaluating the impact of proposed conservation measures, but they should also provide a measure of understanding of the system and its operations to analysts and policy makers who are involved in proposing, analyzing, and implementing such changes.

  9. Energy situation and competitiveness of the aluminium industry

    Energy Technology Data Exchange (ETDEWEB)

    Legler, H.

    1984-04-01

    The west german aluminium industry has heavily run into the wake of price competition; the high energy price level in the FRG in international comparison carries heavy weight. The technological potential of energy saving is limited. The electricity prices to aluminium smelters are politically determined: They depend on the importance which economic policy attaches to the competitiveness of electricity intensive industries. Since the end of the seventies the tendency of improved results in international trade has been broken. Other important supply factors are not advantageous. Compared to a lot of other economies the west german aluminium industry invests too little in research and development. Although the share of unskilled workers is high, it does not seem impossible to close the technological gap. - The environmental protection expenditures are considerable. Energy is not the only problem of the aluminium industry Electricity price subsidies do not produce any effect in the long run. The prospects of cheap electricity in comparison with other nations are not bright. Without a doubt the considerable regional and sectoral discriminations in setting electricity prices could be - and have to be - removed. Then the competition within FRG between electricity users would be less heavily distorted. The electricity price level will tend to drop significantly in an economy which applies more competitive pressure to power companies than today.

    2010-12-01

    The amount of sawmill residue available in Canada to support the emerging cellulosic ethanol industry was examined. A material flow analysis technique was employed to determine the amount of sawmill residue that could possibly be available to the ethanol industry per annum. A combination of two key trends--improved efficiency of lumber recovery and increased uptake of sawmill residues for self-generation and for wood pellet production--have contributed to a declining trend of sawmill residue availability. Approximately 2.3 x 10⁶ bone-dry tons per year of sawmill residue was estimated to be potentially available to the cellulosic ethanol industry in Canada, yielding 350 million liters per year of cellulosic ethanol using best practices. An additional 2.7 billion liters of cellulosic ethanol might be generated from sawmill residue that is currently used for competing wood energy purposes, including wood pellet generation. Continued competition between bioenergy options will reduce the industrial sustainability of the forest industry. Recommendations for policy reforms towards improved industrial sustainability practices are provided.

    1992-03-01

    Six area reported progress in the Energy Efficient Industrialized Housing Research Program during FY 1991. As part of Industry Guidance, meetings were held with steering and technical committees in computers, housing design and manufacturing. This task area enables the program to benefit from the expertise of industry representatives and communicate research results directly to them. As part of the Design Process performance specifications were being developed for the future housing system designed last year. These house designs coordinate and optimize predicted and desirable advances in computerized design processes, materials, components, and manufacturing automation to achieve energy efficiency at reduced first cost. Energy design software were being developed for CAD systems, stressed skin insulating core panel manufacturers; and a prototype energy sales tool. A prototype design was to be developed to integrate one or more subsystems with the building skin. As part of the Manufacturing Process we are developing a manufacturing process simulation and data base to help current and new entrants to the industrialized housing industry in assessing the impact of implementing new manufacturing techniques. For Evaluation we are developing testing plans for six units of housing on the UO campus and the stressed skin insulating core house to be constructed in Oregon. The DOW Chemical test structure will be retrofitted with a tile roof and retested to compare to the dome and conventional construction structures. Calibration of the wind tunnel will be completed so that laboratory tests can be conducted to simulate the ventilation cooling efficiency of houses in design. Research utilization and program management were either aspects of this program.

    This study develops and examines physical energy intensity indicators in five industrial sub-sectors-iron and steel, aluminum, textiles, paper, and cement-and investigates mitigation options for energy related CO{sub 2} emissions (during 1991-2005). Decomposition analysis has been employed to separate the structural effect (share of different products in the sector) from pure intensity effect (efficiency increase through technical improvement) for each industry. The results show that the combined effect (considering both structural and intensity effects together) on both iron and steel and paper and pulp industries is negative while it is positive for aluminum and textiles. The intensity effect for all the industries, barring textiles, is negative showing improvement in energy efficiency; iron and steel in particular, has seen a decrease of 134 PJ in energy consumption owing to improvements in efficiency. However, energy intensity in textiles has risen by 47 PJ due to increased mechanization. Structural effect is positive in aluminum and iron and steel industries indicating a movement towards higher energy-intensive products. In the case of aluminum, positive structural effect dominates over negative intensive effect whereas negative intensive effect dominates iron and steel industry. The paper helps in designing policies for improving productivity and reduce energy consumption in India's manufacturing sector. - Highlights: > The study develops physical energy intensity indicators in industrial sub-sectors of India. > It identifies technological and other options for reduction in energy consumption. > The study quantifies savings in energy as well as CO{sub 2} emissions. > The indicators are useful in examining structural changes.

    The U.S. glass industry is comprised of four primary industry segments--flat glass, container glass, specialty glass, and fiberglass--which together consume $1.6 billion in energy annually. On average, energy costs in the U.S. glass industry account for around 14 percent of total glass production costs. Energy efficiency improvement is an important way to reduce these costs and to increase predictable earnings, especially in times of high energy price volatility. There is a variety of opportunities available at individual plants in the U.S. glass industry to reduce energy consumption in a cost-effective manner. This Energy Guide discusses energy efficiency practices and energy-efficient technologies that can be implemented at the component, process, system, and organizational levels. A discussion of the trends, structure, and energy consumption characteristics of the U.S. glass industry is provided along with a description of the major process steps in glass manufacturing. Expected savings in energy and energy-related costs are given for many energy efficiency measures, based on case study data from real-world applications in glass production facilities and related industries worldwide. Typical measure payback periods and references to further information in the technical literature are also provided, when available. The information in this Energy Guide is intended to help energy and plant managers in the U.S. glass industry reduce energy consumption in a cost-effective manner while maintaining the quality of products manufactured. Further research on the economics of the measures--as well on as their applicability to different production practices--is needed to assess potential implementation of selected technologies at individual plants.

    2011-01-01

    We introduce a machine learning model to predict atomization energies of a diverse set of organic molecules, based on nuclear charges and atomic positions only. The problem of solving the molecular Schr\\"odinger equation is mapped onto a non-linear statistical regression problem of reduced complexity. Regression models are trained on and compared to atomization energies computed with hybrid density-functional theory. Cross-validation over more than seven thousand small organic molecules yields a mean absolute error of ~10 kcal/mol. Applicability is demonstrated for the prediction of molecular atomization potential energy curves.

    Visible emission spectra were acquired from neutral atoms sputtered by 35–60 keV Kr{sup +} ions from a polycrystalline tungsten surface. Mean velocities of excited tungsten atoms in seven different 6p states were also obtained via the dependence of photon intensities on the distance from the surface. The average velocities parallel to the surface normal varied by factors of 2–4 for atoms in the different 6p energy levels. However, they were almost independent of the incident ion kinetic energy. The 6p-level energy dependence indicated that the velocities of the excited atoms were determined by inelastic processes that involve resonant charge exchange.

    1999-04-01

    This paper discusses markets related with energy conservation and environment preservation in industrial enterprises in Thailand. The present Thailand is not in a situation that investments are made into environmental businesses or energy saving businesses. However, the attitude of the government toward environment is that emphasis is placed on solving the environmental pollution problems. Laws and regulations are defined for assistance in environment preservation to corporations making efforts to increase export, resource protection and energy conservation. These measures lead to expectation on bright future in developing technologies and markets related to environment preservation and energy conservation. Control of wastes by using clean technologies and enhancement in productivity are very important issues for the export of Thailand partly because European countries and America set these requirements as a condition for transaction. The markets related to energy conservation and environment preservation are anticipated of participation from such businesses as consultants, device manufacturers, and inspection and analysis of environmental effects.

    The conventional approach for energy saving in a process system is to maximize heat recovery without changing any process conditions by using pinch technology. “Self-heat recuperation technology” was developed to achieve further energy saving in the process system by eliminating the necessity for any external heat input, such as firing or imported steam. Advanced Energy Saving and its Applications in Industry introduces the concept of self-heat recuperation and the application of such technology to a wide range of processes from heavy chemical complexes to other processes such as drying and gas separation processes, which require heating and cooling during operation.   Conventional energy saving items in a utility system are applied and implemented based on a single site approach, however, when looking at heavy chemical complexes, it was apparent that the low-grade heat discharged as waste from a refinery could also be used in an adjacent petrochemical plant. There could therefore be a large energy savin...

    Industry utilizes very complex systems, consisting of equipment and their human interface, which are organized to meet the production needs of the business. Effective and sustainable energy efficiency programs in an industrial setting require a systems approach to optimize the integrated whole while meeting primary business requirements. Companies that treat energy as a manageable resource and integrate their energy program into their management practices have an organizational context to continually seek opportunities for optimizing their energy use. The purpose of an energy management system standard is to provide guidance for industrial and commercial facilities to integrate energy efficiency into their management practices, including fine-tuning production processes and improving the energy efficiency of industrial systems. The International Organization for Standardization (ISO) has identified energy management as one of its top five priorities for standards development. The new ISO 50001 will establish an international framework for industrial, commercial, or institutional facilities, or entire companies, to manage their energy, including procurement and use. This standard is expected to achieve major, long-term increases in energy efficiency (20percent or more) in industrial, commercial, and institutional facilities and to reduce greenhouse gas (GHG) emissions worldwide.This paper describes the impetus for the international standard, its purpose, scope and significance, and development progress to date. A comparative overview of existing energy management standards is provided, as well as a discussion of capacity-building needs for skilled individuals to assist organizations in adopting the standard. Finally, opportunities and challenges are presented for implementing ISO 50001 in emerging economies and developing countries.

  1. The thermoelectric power industry and the Italian energy program

    Energy Technology Data Exchange (ETDEWEB)

    Ninni, A.; Villa, A.

    The reduction of technological and market uncertainty in the thermoelectric power industry can be considered as one of the most important consequences of a large public demand program acting on the supply sector. However, possible results must be analyzed by taking into account the features of the demand (amount, time sharing, degree of certainty of public commitment, behaviour of the buyer-user utility), and the features of the supply sector (its competitiveness and degree of technological content, vis-a-vis the international market and the main foreign suppliers). From the analysis in this article, the reduction of the technological gap in industry results as a likely product of the energy program, while the size and the uncertainty of the program, coupled with some particular behaviour of the utility, do not seem to be able by themselves to trigger off a permanent process of improvement of the relative international competitiveness of the industry.

  2. Quantitative material analysis by dual-energy computed tomography for industrial NDT applications

    2011-05-01

    Dual-energy computed tomography (DECT) is an established method in the field of medical CT to obtain quantitative information on a material of interest instead of mean attenuation coefficients only. In the field of industrial X-ray imaging dual-energy techniques have been used to solve special problems on a case-by-case basis rather than as a standard tool. Our goal is to develop an easy-to-use dual-energy solution that can be handled by the average industrial operator without the need for a specialist. We are aiming at providing dual-energy CT as a measurement tool for those cases where qualitative images are not enough and one needs additional quantitative information (e.g. mass density ρ and atomic number Z) about the sample at hand. Our solution is based on an algorithm proposed by Heismann et al. (2003) [1] for application in medical CT . As input data this algorithm needs two CT data sets, one with low (LE) and one with high effective energy (HE). A first order linearization is applied to the raw data, and two volumes are reconstructed thereafter. The dual-energy analysis is done voxel by voxel, using a pre-calculated function F(Z) that implies the parameters of the low and high energy measurement (such as tube voltage, filtration and detector sensitivity). As a result, two volume data sets are obtained, one providing information about the mass density ρ in each voxel, the other providing the effective atomic number Z of the material therein. One main difference between medical and industrial CT is that the range of materials that can be contained in a sample is much wider and can cover the whole range of elements, from hydrogen to uranium. Heismann's algorithm is limited to the range of elements Z=1-30, because for Z>30 the function F(Z) as given by Heismann is not a bijective function anymore. While this still seems very suitable for medical application, it is not enough to cover the complete range of industrial applications. We therefore investigated the

  6. Industrial applications of hot dry rock geothermal energy

    Energy Technology Data Exchange (ETDEWEB)

    1992-09-01

    Geothermal resources in the form of naturally occurring hot water or steam have been utilized for many years. While these hydrothermal resources are found in many places, the general case is that the rock at depth is hot, but does not contain significant amounts of mobile fluid. An extremely large amount of geothermal energy is found around the world in this hot dry rock (HDR). Technology has been under development for more than twenty years at the Los Alamos National Laboratory in the United States and elsewhere to develop the technology to extract the geothermal energy from HDR in a form useful for electricity generation, space heating, or industrial processing. HDR technology is especially attractive for industrial applications because of the ubiquitous distribution of the HDR resource and the unique aspects of the process developed to recover it. In the HDR process, as developed at Los Alamos, water is pumped down a well under high pressure to open up natural joints in hot rock and create an artificial geothermal reservoir. Energy is extracted by circulating water through the reservoir. Pressurized hot water is returned to the surface through the production well, and its thermal energy is extracted for practical use. The same water is then recirculated through the system to mine more geothermal heat. Construction of a pilot HDR facility at Fenton Hill, NM, USA, has recently been completed by the Los Alamos National Laboratory. It consists of a large underground reservoir, a surface plant, and the connecting wellbores. This paper describes HDR technology and the current status of the development program. Novel industrial applications of geothermal energy based on the unique characteristics of the HDR energy extraction process are discussed.

  7. Global scenarios for the energy industry: challenge and response

    Energy Technology Data Exchange (ETDEWEB)

    1991-01-01

    Three areas of far reaching change that will affect the future of the energy industry are identified - geopolitical changes, such as the collapse of communist regimes in Eastern Europe and the Soviet Union, the relative decline of economic importance of the USA and the stimulus of European Community programmes; changes and difficulties in the international economy such as disagreement over trade and foreign direct investment; and thirdly, changing attitudes towards man's impact on the natural environment. These changes suggest two different images of the future, one called 'global mercantilism' and the other 'sustainable change'. In the first, the main global challenge is to deal with decline in the hegemonic position of the USA and Japan and the instability in international markets - the energy industry here faces new rules for business; in the 'sustainable world' the main challenge is to deal with common problems with implications for the redefining of the value of clean fuels and processes as well as substantial reconstruction of the energy industry. 10 figs.

    2003-07-01

    This presentation offered some perspectives in security risk management as it relates to the energy sector. Since the events of September 11, 2001 much attention has been given to terrorism and the business is reviewing protection strategies. The paper made reference to each of the following vulnerabilities in the energy sector: information technology, globalization, business restructuring, interdependencies, political/regulatory change, and physical/human factors. The vulnerability of information technology is that it can be subject to cyber and virus attacks. Dangers of globalization lie in privacy and information security, forced nationalization, organized crime, and anti-globalization efforts. It was noted that the Y2K phenomenon provided valuable lessons regarding interdependencies and the effects of power outages, water availability, transportation disruption, common utility corridor accidents, and compounding incidents. The paper also noted the conflict between the government's desire to have a resilient infrastructure that can withstand and recover from attacks versus a company's ability to afford this capability. The physical/human factors that need to be considered in risk management include crime, domestic terrorism, and disasters such as natural disasters, industrial disasters and crisis. The energy industry has geographically dispersed vulnerable systems. It has done a fair job of physical security and has good emergency management practices, but it was noted that the industry cannot protect against all threats. A strategy of vigilance and awareness is needed to deal with threats. Other strategies include contingency planning, physical security, employee communication, and emergency response plans. tabs., figs.

    The stopping of a charged particle by isolated atoms is investigated theoretically using an 'atomic plasma' model in which atomic oscillator strengths are replaced by the plasma frequency spectrum. The plasma-frequency correction factor for individual electron motion proposed by Pines (1953) is incorporated, and atomic mean excitation energies are calculated for atoms through Sr. The results are compared in a graph with those obtained theoretically by Inokuti et al. (1978, 1981) and Dehmer et al. (1975) and with the experimental values compiled by Seltzer and Berger (1982): good agreement is shown.

    Understanding atom-ion collision dynamics is at the heart of the growing field of ultra-cold atom-ion physics. The naive picture of a hot ion sympathetically-cooled by a cold atomic bath doesn't hold due to the time dependent potentials generated by the ion Paul trap. The energy scale of the atom-ion system is determined by a combination of the atomic bath temperature, the ion's excess micromotion (EMM) and the back action of the atom-ion attraction on the ion's position in the trap. However, it is the position dependent ion's inherent micromotion which acts as an amplifier for the ion's energy during random consecutive collisions. Due to this reason, the ion's energy distribution deviates from Maxwell-Boltzmann (MB) characterized by an exponential tail to one with power-law tail described by Tsallis q-exponential function. Here we report on the observation of a strong deviation from MB to Tsallis energy distribution of a trapped ion. In our experiment, a ground-state cooled 88 Sr+ ion is immersed in an ultra-cold cloud of 87 Rb atoms. The energy scale is determined by either EMM or solely due to the back action on the ion position during a collision with an atom in the trap. Energy distributions are obtained using narrow optical clock spectroscopy.

    We have calculated the energy spectra of one- and two-electron atoms (ions) centered in an impenetrable spherical box by variational method with B-splines as basis functions. Accurate results are obtained for both large and small radii of confinement. The critical box radius of confined hydrogen atom is also calculated to show the usefulness of our method. A partial energy degeneracy in confined hydrogen atom is found when the radius of spherical box is equal to the distance at which a node of single-node wavefunctions of free hydrogen atom is located.

    We analyze the electronic structure of atoms in the first, second and third periods using the electronic kinetic energy density and stress tensor density, which are local quantities motivated by quantum field theoretic consideration, specifically the rigged quantum electrodynamics. We compute the zero surfaces of the electronic kinetic energy density, which we call the electronic interfaces, of the atoms. We find that their sizes exhibit clear periodicity and are comparable to the conventional atomic and ionic radii. We also compute the electronic stress tensor density and its divergence, tension density, of the atoms, and discuss how their electronic structures are characterized by them.

    Barklem, Paul S

    2016-01-01

    A theoretical method for the estimation of cross sections and rates for excitation and charge transfer processes in low-energy hydrogen atom collisions with neutral atoms, based on an asymptotic two-electron model of ionic-covalent interactions in the neutral atom-hydrogen atom system, is presented. The calculation of potentials and non-adiabatic radial couplings using the method is demonstrated. The potentials are used together with the multi-channel Landau-Zener model to calculate cross sections and rate coefficients. The main feature of the method is that it employs asymptotically exact atomic wavefunctions, which can be determined from known atomic parameters. The method is applied to Li+H, Na+H, and Mg+H collisions, and the results compare well with existing detailed full-quantum calculations. The method is applied to the astrophysically important problem of Ca+H collisions, and rate coefficients are calculated for temperatures in the range 1000-20000 K.

    Since 1957, the International Atomic Energy Agency (IAEA) has worked to ensure the safe and responsible promotion of nuclear technology throughout the world. The IAEA operates at the intersection of the Nuclear Nonproliferation Treaty’s (NPT) fourth and third articles, which guarantee Parties to the Treaty the right to peaceful uses of nuclear technology, provided those activities are placed under safeguards verified by the IAEA. However, while the IAEA has enjoyed substantial success and prestige in the international community, there is a concern that its resources are being stretched to a point where it may no longer be possible to execute its multifaceted mission in its entirety. As noted by the Director General (DG) in 2008, demographics suggest that every aspect of the IAEA’s operations will be in higher demand due to increasing reliance on non-carbon-based energy and the concomitant nonproliferation, safety, and security risks that growth entails. In addition to these nuclear energy concerns, the demand for technical developmental assistance in the fields of food security, resource conservation, and human health is also predicted to increase as the rest of the world develops. Even with a 100% value-for-money rating by the U.S. Office of Management and Budget (OMB) and being described as an “extraordinary bargain” by the United Nations Secretary-General’s High-level Panel on Threats, Challenges and Change, real budget growth at the Agency has been limited to zero-real growth for a better part of the last two decades. Although the 2012 regular budget (RB) received a small increase for most programs, the 2013 RB has been set at zero-real growth. As a result, the IAEA has had to defer infrastructure investments, which has hindered its ability to provide the public goods its Members seek, decreased global security and development opportunities, and functionally transformed the IAEA into a charity, dependent on extrabudgetary (EB) contributions to sustain

    2004-02-10

    industrial space over the last 5 years. It is one reason that China consumed over 60% of the world's cement production in 2003 (NBS 2004). Energy consumption in Shanghai has been growing at 6-8% annually, with the growth of electricity demand at over 10% per year. Shanghai, with very limited local energy resources, relies heavily on imported coal, oil, natural gas, and electricity. While coal still constitutes over half of Shanghai's energy consumption, oil and natural gas use have been growing in importance. Shanghai is the major market for China's West to East (natural gas) Pipeline (WEP). With the input from WEP and off-shore pipelines, it is expected that natural gas consumption will grow from 250 million cubic meters in 2000 to 3000-3500 million cubic meters in 2005. In order to secure energy supply to power Shanghai's fast-growing economy, the Shanghai government has set three priorities in its energy strategy: (1) diversification of its energy structure, (2) improving its energy efficiency, and (3) developing renewable and other cleaner forms of energy. Efficiency improvements are likely to be most critical, particularly in the near future, in addressing Shanghai's energy security, especially the recent electricity shortage in Shanghai. Commercial buildings and industries consume the majority of Shanghai's, as well as China's, commercial energy. In the building sector, Shanghai has been very active implementing energy efficiency codes for commercial and residential buildings. Following a workshop on building codes implementation held at LBNL for senior Shanghai policy makers in 2001, the Shanghai government recently introduced an implementation guideline on residential building energy code compliance for the downtown area of Shanghai to commence in April, 2004, with other areas of the city to follow in 2005. A draft code for commercial buildings has been developed as well. In the industrial sector, the Shanghai government started an

    With the increasing cost of energy and the rising concerns over the environment, interest in energy saving methods is growing in the industry sector. In the pulp and paper sector, energy represents a significant part of costs and the aims of this paper are first, to demonstrate that there is a potential for energy use reduction in the pulp and paper industry and secondly, to show how it can be achieved. Benchmarking studies have been carried out for both the kraft market pulp and newsprint sectors; in both cases the energy consumption of existing Canadian mills was compared to that of a modern mill using the best current technologies. Results showed that in both sectors, the application of best practices could result in significant savings. This study demonstrated that the application of current technologies in existing mills would yield significant energy use reductions.

    The U.S. pharmaceutical industry consumes almost $1 billion in energy annually. Energy efficiency improvement is an important way to reduce these costs and to increase predictable earnings, especially in times of high energy price volatility. There are a variety of opportunities available at individual plants in the U.S. pharmaceutical industry to reduce energy consumption in a cost-effective manner. This Energy Guide discusses energy efficiency practices and energy efficient technologies that can be implemented at the component, process, system, and organizational levels. A discussion of the trends, structure, and energy consumption characteristics of the U.S. pharmaceutical industry is provided along with a description of the major process steps in the pharmaceutical manufacturing process. Expected savings in energy and energy-related costs are given for many energy efficiency measures, based on case study data from real-world applications in pharmaceutical and related facilities worldwide. Typical measure payback periods and references to further information in the technical literature are also provided, when available. The information in this Energy Guide is intended to help energy and plant managers reduce energy consumption in a cost-effective manner while meeting regulatory requirements and maintaining the quality of products manufactured. At individual plants, further research on the economics of the measures?as well as their applicability to different production practices?is needed to assess potential implementation of selected technologies.

  20. Energy use in the animal-feeds industry

    Fuel and electricity use in the animal feeds industry is discussed. Data were collected by postal survey and by detailed energy survey from plant records. Energy conservation measures are discussed. Large energy savings are unlikely in lucerne pellet production but significant savings in imported fuel oil could be made by conversion to coal or other indigenous fuels. When heat pump technology has improved it may be economically feasible to use a heat pump to recover heat from the dryer outlet air and use it to preheat the incoming air stream. Electricity savings are unlikely in feed mills but the boiler fuel consumption can by reduced by better situation of boilers and upgrading of steam reticulation systems. Energy consumption in dog biscuit factories can be reduced by similar methods to those suggested in the biscuit baking industry report, in particular conversion to direct gas heating (where available) and waste heat recovery for hot water production offer potential savings. Methods used to manufacture processed animal foods differ between factories and a general list of conservation measures could not be prepared. Useful savings are likely by reduced baseload boiler fuel consumption and waste heat recovery for hot water production.

    The public enjoy an important role in the development of China's new energy industry. However, the role has not attracted sufficient attention. By the way of field investigation, the paper acquired the first hand data of the public cognition on the China's new energy industry. Survey data showed that the public enjoyed awareness of China's new energy industry to some extent. And the public had optimistic expectations on the future development of new energy industry. Moreover, there were obvious differences in the degree of public's familiarity with different new energy varieties. The education level and age of the individual public had a significant impact on his awareness of China's new energy industry. To raise public participation in China's new energy industry, it entailed highlighting the status of the public in China's new energy industry, increasing the publicity of the new energy industry with different measures for different types of public group.

    Reflection electron energy loss spectra from some insulating materials (CaCO{sub 3}, Li{sub 2}CO{sub 3}, and SiO{sub 2}) taken at relatively high incoming electron energies (5–40 keV) are analyzed. Here, one is bulk sensitive and a well-defined onset of inelastic excitations is observed from which one can infer the value of the band gap. An estimate of the band gap was obtained by fitting the spectra with a procedure that includes the recoil shift and recoil broadening affecting these measurements. The width of the elastic peak is directly connected to the mean kinetic energy of the atom in the material (Doppler broadening). The experimentally obtained mean kinetic energies of the O, C, Li, Ca, and Si atoms are compared with the calculated ones, and good agreement is found, especially if the effect of multiple scattering is taken into account. It is demonstrated experimentally that the onset of the inelastic excitation is also affected by Doppler broadening. Aided by this understanding, we can obtain a good fit of the elastic peak and the onset of inelastic excitations. For SiO{sub 2}, good agreement is obtained with the well-established value of the band gap (8.9 eV) only if it is assumed that the intensity near the edge scales as (E − E{sub gap}){sup 1.5}. For CaCO{sub 3}, the band gap obtained here (7 eV) is about 1 eV larger than the previous experimental value, whereas the value for Li{sub 2}CO{sub 3} (7.5 eV) is the first experimental estimate.

    We investigate the resonance interaction energy between two uniformly accelerated identical atoms, interacting with the scalar field or the electromagnetic field in the vacuum state, in the reference frame coaccelerating with the atoms. We assume that one atom is excited and the other in the ground state, and that they are prepared in their correlated symmetric or antisymmetric state. Using perturbation theory, we separate, at the second order in the atom-field coupling, the contributions of vacuum fluctuations and radiation reaction field to the energy shift of the interacting system. We show that only the radiation reaction term contributes to the resonance interaction between the two atoms, while Unruh thermal fluctuations, related to the vacuum fluctuations contribution, do not affect the resonance interatomic interaction. We also show that the resonance interaction between two uniformly accelerated atoms, recently investigated in the comoving (locally inertial) frame, can be recovered in the coaccelerate...

    2010-04-01

    Full Text Available Areal roughness parameters always need to be under control in the thin film solar cell industry because of their close relationship with the electrical efficiency of the cells. In this work, these parameters are evaluated for measurements carried out in a typical fabrication area for this industry. Measurements are made using a portable atomic force microscope on the CNC diamond cutting machine where an initial sample of transparent conductive oxide is cut into four pieces. The method is validated by making a comparison between the parameters obtained in this process and in the laboratory under optimal conditions. Areal roughness parameters and Fourier Spectral Analysis of the data show good compatibility and open the possibility to use this type of measurement instrument to perform in situ quality control. This procedure gives a sample for evaluation without destroying any of the transparent conductive oxide; in this way 100% of the production can be tested, so improving the measurement time and rate of production.

    Considerable effort is being applied to develop multiple-energy industrial CT techniques for materials characterization. Multiple-energy CT can provide reliable estimates of effective Z (Z{sub eff}), weight fraction, and rigorous calculations of absolute density, all at the spatial resolution of the scanner. Currently, a wide variety of techniques exist for CT scanners, but each has certain problems and limitations. Ultimately, the best multi-energy CT technique would combine the qualities of accuracy, reliability, and wide range of application, and would require the smallest number of additional measurements. We have developed techniques for calculating material properties of industrial objects that differ somewhat from currently used methods. In this paper, we present our methods for calculating Z{sub eff}, weight fraction, and density. We begin with the simplest case -- methods for multiple-energy CT using isotopic sources -- and proceed to multiple-energy work with x-ray machine sources. The methods discussed here are illustrated on CT scans of PBX-9502 high explosives, a lexan-aluminum phantom, and a cylinder of glass beads used in a preliminary study to determine if CT can resolve three phases: air, water, and a high-Z oil. In the CT project at LLNL, we have constructed several CT scanners of varying scanning geometries using {gamma}- and x-ray sources. In our research, we employed two of these scanners: pencil-beam CAT for CT data using isotopic sources and video-CAT equipped with an IRT micro-focal x-ray machine source.

    Looking at the composition of energy resources import of Korea per each country, Australian-made import takes up 11.8% of total energy resources import. It possesses the highest import composition of 30.5% when petroleum sector is excluded. In the order of Korea`s mineral import per each country, Australia still keep the number one position every year though Korea keep promoting the diversification of import sources. In the mean time, reflecting on the treatment aspect of import country of Australia, when Korea`s energy, the import size of resources, import intensity of Australia`s primary raw material resources and international resources situation are considered, Korea is thought to receive less treatment from Australia as the second export country of Australia than Japan who is the number one export country of Australia, relatively. Though the increase ratio of Korean tourists in Australia is the highest for the past few years and international promotion effect shows big with the IMF financial support of Korea who faces sudden economic crisis recently as a momentum, sincere evaluation through in-depth analysis between Korea and Australia is still in the initial stage. The necessity to diagnosis the general political and economic structure of Australia more in detail emerges as trade volume between two countries keep growing, esp. in the import of energy and resources sectors, the number of visits between two countries keep increasing. Therefore, the purpose of this study lies mainly in the structure of the new Australian government, general macroeconomics structure and the understanding of energy industry-related status such as energy supply and demand, development status of energy, related laws, and government`s energy agencies, etc. 6 refs., 3 figs., 22 tabs.

    A new method for making cement is proposed. It is based on the use of CaF{sub 2} and CaSO{sub 4} for partial replacement of the usual raw materials in cement manufacturing. This paper shows the feasibility of the proposed method on an industrial scale. A test carried out in a Spanish cement factory (1500 t yield of the new cement) has revealed that the mehtod can not only be adapted to the current technology but also requires a much lower energy expenditure. The final product is shown to have excellent properties in comparison with OPC. (orig.).

    The drying of products -meaning the extraction of water or excess humidity down to adequate levels for its conservation and final presentation- demands a large amount of energy, mainly from fuels of fossil origin. Nevertheless, from the standpoint of the energy efficiency, the burning of fuels at very high temperature for using them at a very low temperature, represents an astonishing energy waste, which can be clearly established by means of an energy and exergy balance of these drying installations. In this study the methodology for the energy analysis for industrial drying systems is presented and it is applied to different practical cases. The efficiency of the entire system is evaluated and the losses for each concept, in order to obtain the potential energy saving. [Espanol] El secado de productos, entendido como la extraccion de agua o humedad en exceso, hasta niveles adecuados para su conservacion o presentacion final, demanda una gran cantidad de energeticos, principalmente de origen fosil. No obstante, desde el punto de vista de la eficiencia energetica, el quemar combustible a muy alta temperatura para emplearlos a una muy baja, representa un dispendio energetico impresionante, lo cual puede ser claramente establecido mediante el balance energetico y exergetico de dichas instalaciones de secado. En el presente estudio se presenta la metodologia de analisis energetico de sistemas industriales de secado y se aplica a distintos casos practicos.

The results of investigations made at a large pulp and paper facility in Switzerland are presented and analysed. Data models of the steam and condensate networks and of the processes involved are examined. An additional model of the sulphur loop has been also elaborated. From this analysis, a list of required measurements has been developed. Several performance indicators have also been calculated: A systematic analysis method developed to identify sections where condensate could be recovered is discussed. A systematic definition of the hot and cold streams in the process is being developed in order to compute the minimum energy requirements of the process. Evaluating this minimum energy requirement from the data available is to be used to prepare definitions of the energy savings possible.

    Based on the total-factor energy efficiency framework, this paper calculates China's industrial energy efficiency and CO2 emissions reduction potential from 2000 to 2009 by utilizing the directional distance function and data envelopment analysis. The empirical results show that: China's industrial overall energy effi- ciency is relatively lower while the emis-sions reduction potential is relatively greater, given the optimum production frontier. Sig- nificant indus-trial disparities of energy efficiency and emissions reduction potential exist. Energy efficiency and emis-sions reduc- tion potential significantly show different tendencies of industrial dynamic variation. This paper suggests the Chinese government impose differential carbon taxes, flexibly utilize carbon market me-cha-nism, strengthen energy-saving technological R&D, promote the utilization of renewable energy, and strengthen environmental supervision and regulation, so as to improve China's industrial en- ergy efficiency and reduce CO2 emissions.

    1976-04-01

    Energy transfer in collisions of satellite-speed (7,000 m/s) helium atoms with a cleaned 6061-T6 satellite-type aluminum surface was investigated by use of the molecular-beam technique. The amount of energy transferred was determined from the measured energy of the molecular-beam and the measured spatial and energy distributions of the reflected atoms. Spatial distributions of helium atoms scattered from a 6061-T6 aluminum surface were measured. The scattering pattern exhibits a prominent backscattering, probably due to the gross surface roughness and/or the relative lattice softness of the aluminum surface. Energy distributions of reflected helium atoms from the same surface were measured for six different incidence angles. For each incidence angle, distributions were measured at approximately sixty scattering positions. At a given scattering position, the energy spectra of the reflected helium atoms and the background gas were obtained by use of the retarding-field energy analyzer. (auth)

    In this paper the correlation between the kinetic energy of helium atoms and the probability of field ionization is investigated by exploiting the narrow velocity distribution of supersonic molecular beams. Field ionization measurements were carried out on supersonic helium beams at 298 K and 95 K corresponding to energies of about 65 meV and 20 meV, respectively, for the individual atoms. The field ionization was performed with a tungsten tip, radius of curvature 12 nm, kept at room temperature. The ionization probability was found to increase by about a factor 10 when the beam was cooled from 298 K to 95 K. The results presented in this paper are of importance for improving the understanding of field ionization and for the development of a new detector for helium and other molecular beams.

    This report provides information on the energy savings, costs, and carbon dioxide emissions reductions associated with implementation of a number of technologies and measures applicable to the cement industry. The technologies and measures include both state-of-the-art measures that are currently in use in cement enterprises worldwide as well as advanced measures that are either only in limited use or are near commercialization. This report focuses mainly on retrofit measures using commercially available technologies, but many of these technologies are applicable for new plants as well. Where possible, for each technology or measure, costs and energy savings per tonne of cement produced are estimated and then carbon dioxide emissions reductions are calculated based on the fuels used at the process step to which the technology or measure is applied. The analysis of cement kiln energy-efficiency opportunities is divided into technologies and measures that are applicable to the different stages of production and various kiln types used in China: raw materials (and fuel) preparation; clinker making (applicable to all kilns, rotary kilns only, vertical shaft kilns only); and finish grinding; as well as plant wide measures and product and feedstock changes that will reduce energy consumption for clinker making. Table 1 lists all measures in this report by process to which they apply, including plant wide measures and product or feedstock changes. Tables 2 through 8 provide the following information for each technology: fuel and electricity savings per tonne of cement; annual operating and capital costs per tonne of cement or estimated payback period; and, carbon dioxide emissions reductions for each measure applied to the production of cement. This information was originally collected for a report on the U.S. cement industry (Worrell and Galitsky, 2004) and a report on opportunities for China's cement kilns (Price and Galitsky, in press).

    This report summarizes technical progress during the program “Optical Fiber High Temperature Sensor Instrumentation for Energy Intensive Industries”, performed by the Center for Photonics Technology of the Bradley Department of Electrical and Computer Engineering at Virginia Tech. The objective of this program was to use technology recently invented at Virginia Tech to develop and demonstrate the application of self-calibrating optical fiber temperature and pressure sensors to several key energy-intensive industries where conventional, commercially available sensors exhibit greatly abbreviated lifetimes due primarily to environmental degradation. A number of significant technologies were developed under this program, including • a laser bonded silica high temperature fiber sensor with a high temperature capability up to 700°C and a frequency response up to 150 kHz, • the world’s smallest fiber Fabry-Perot high temperature pressure sensor (125 x 20 μm) with 700°C capability, • UV-induced intrinsic Fabry-Perot interferometric sensors for distributed measurement, • a single crystal sapphire fiber-based sensor with a temperature capability up to 1600°C. These technologies have been well demonstrated and laboratory tested. Our work plan included conducting major field tests of these technologies at EPRI, Corning, Pratt & Whitney, and Global Energy; field validation of the technology is critical to ensuring its usefulness to U.S. industries. Unfortunately, due to budget cuts, DOE was unable to follow through with its funding commitment to support Energy Efficiency Science Initiative projects and this final phase was eliminated.

    Energy is mainly consumed by the urban industry system, thus grading industrial sectors for their energy consumption may help to identify the concerned industrial sectors and provide necessary information for industrial energy management in China's industrialization and urbanization. In present article, based on a review of the fundamental relationships between energy consumption and industrial sectors, the contribution rates and energy efficiency of industrial sectors are chosen as typical parameters for energy consumption. The concept of distance index of industrial sectors for energy consumption is defined through China's average level as a reference base. The grade of industrial sectors in energy consumption is classed into 9 types from extreme advantage to extreme disadvantage according to the scope of distance index values, and the types of industrial sectors that need to be more concerned are pointed out. Taking Chongqing as a case study, the application for grading industrial sectors for their energy consumption was exhibited, by which, the main industrial sectors are grated and the industrial sectors that should be special concerned in energy management are determined.

  9. Energy conservation by hyperfiltration: food industry background literature survey

    Energy Technology Data Exchange (ETDEWEB)

    1980-04-15

    The application of hyperfiltration to selected food product streams and food processing wastewaters for energy conservation was examined. This literature survey had led to the following conclusions: no research has been conducted in the food industry using membranes with hot process streams due to the temperature limitation (< 40/sup 0/C) of the typically studied cellulose acetate membranes; based on the bench-scale research reviewed, concentration of fruit and vegetable juices with membranes appears to be technically feasible; pretreatment and product recovery research was conducted with membranes on citrus peel oil, potato processing and brine wastewaters and wheys. The experiments demonstrated that these applications are feasible; many of the problems that have been identified with membranes are associated with either the suspended solids or the high osmotic pressure and viscosity of many foods; research using dynamic membranes has been conducted with various effluents, at temperatures to approx. 100/sup 0/C, at pressures to 1200 psi and with suspended solids to approx. 2%; and, the dynamic membrane is being prototype tested by NASA for high temperature processing of shower water. The literature review substantiates potential for dynamic membrane on porous stainless tubes to process a number of hot process and effluent streams in the food processing industry. Hot water for recycle and product concentrations are major areas with potential for economic application. The two plants involved in the first phase of the project should be reviewed to identify potential energy conservation applications. As many as possible of the conservation applications should be tested during the screening phase at each site. The most promising applications at each site should be evaluated more intensively to establish engineering estimates of the economics of this technology for the canned fruit and vegetable segment of the food industry.

  11. US Energy Industry Financial Developments, 1993 fourth quarter, April 1994

    Energy Technology Data Exchange (ETDEWEB)

    1994-04-14

    This report traces key financial trends in the US energy industry for the fourth quarter of 1993. Financial data (only available for publicly-traded US companies) are included in two broad groups -- fossil fuel production and rate-regulated electric utilities. All financial data are taken from public sources such as energy industry corporate reports and press releases, energy trade publications, and The Wall Street Journal`s Earnings Digest; return on equity is calculated from data available from Standard and Poor`s Compustat data service. Since several major petroleum companies disclose their income by lines of business and geographic area, these data are also presented in this report. Although the disaggregated income concept varies by company and is not strictly comparable to corporate income, relative movements in income by lines of business and geographic area are summarized as useful indicators of short-term changes in the underlying profitability of these operations. Based on information provided in 1993 fourth quarter financial disclosures, the net income for 82 petroleum companies -- including 18 majors -- was unchanged between the fourth quarter of 1992 and the fourth quarter of 1993. An 18-percent decline in crude oil prices resulted in a deterioration of the performance of upstream (oil and gas production) petroleum companies during the final quarter of 1993. However, prices for refined products fell much less than the price of crude oil, resulting in higher refined product margins and downstream (refining, marketing and transport) petroleum earnings. An increase in refined product demand also contributed to the rise in downstream income.

    A new approach for computing the atom-in-molecule [quantum theory of atoms in molecule (QTAIM)] energies in Kohn-Sham density-functional theory is presented and tested by computing QTAIM energies for a set of representative molecules. In the new approach, the contribution for the correlation-kinetic energy (T(c)) is computed using the density-functional theory virial relation. Based on our calculations, it is shown that the conventional approach where atomic energies are computed using only the noninteracting part of the kinetic energy might be in error by hundreds of kJ/mol.

    This report is one of a series of reports that Idaho National Laboratory and National Renewable Energy Laboratory are producing to investigate the technical and economic aspects of nuclear-renewable hybrid energy systems (N-R HESs). Previous reports provided results of an analysis of two N-R HES scenarios. This report builds that analysis with a Texas-synthetic gasoline scenario providing the basis in which the N-R HES sells heat directly to an industrial customer. Subsystems were included that convert electricity to heat thus allowing the renewable energy subsystem to generate heat and benefit from that revenue stream. Nuclear and renewable energy sources are important to consider in the energy sector's evolution because both are considered to be clean and non-carbon emitting energy sources.

  15. Forecasting energy demand and CO{sub 2}-emissions from energy production in the forest industry

    Malinen, H.

    1997-12-31

    The purpose of this study was to develops new energy forecasting methods for the forest industry energy use. The scenarios have been the most commonly used forecasts, but they require a lot of work. The recent scenarios, which are made for the forest industry, give a wide range of results; e.g. from 27,8 TWh to 38 TWh for electricity use in 2010. There is a need for more simple and accurate methods for forecasting. The time scale for the study is from 1975 to 2010, i.e. 36 years. The basic data for the study is collected from time period 1975 - 1995. It includes the wood use, production of main product categories and energy use in the forest industry. The factors affecting energy use at both industry level and at mill level are presented. The most probable technology trends, which can have an effect on energy production and use and CO{sub 2}-emissions are studied. Recent forecasts for the forest industry energy use till the year 2010 are referred and analysed. Three alternative forecasting methods are studied more closely. These methods are (a) Regression analysis, (b) Growth curves and (c) Delphi-method. Total electricity demand, share of purchased electricity, total fuel demand and share of process-based biofuels are estimated for the time period 1996 - 2010. The results from the different methods are compared to each other and to the recent scenarios. The comparison is made for the results concerning the energy use and the usefulness of the methods in practical work. The average energy consumption given by the forecasts for electricity was 31,6 TWh and for fuel 6,2 Mtoe in 2010. The share of purchased electricity totalled 73 % and process based fuels 77 %. The figures from 1995 are 22,8 TWh, 5,5 Mtoe, 64 % and 68 % respectively. All three methods were suitable for forecasting. All the methods required less working hours and were easier to use than scenarios. The methods gave results with a smaller deviation than scenarios, e.g. with electricity use in 2010 from

    Using the "Pseudo-invariant eigen-operator" method we find the energy-gap of the Jaynes-Cummings Hamiltonian model of an atom-cavity system. This model takes the atomic centre-of-mass motion into account. The supersymmetric structure is involved in the Hamiltonian of an atom-cavity system. By selecting suitable supersymmetric generators and using supersymmetric transformation the Hamiltonian is diagonalized and energy eigenvectors are obtained.

    We observe strong energy-dependent quantum defects in the scaled-energy Stark spectra for |M|=1 Rydberg states of barium atoms at three scaled energies: ε= -2.000, ε= -2.500 and ε=-3.000. In an attempt to explain the observations, theoretical calculations of closed orbit theory based on a model potential including core effect are performed for non-hydrogenic atoms. While such a potential has been uniformly successful for alkali atoms with a single valence electron, it fails to match experimental results for barium atoms in the 6snp Rydberg states with two valence electrons. Our study points out that this discrepancy is due to the strong perturbation from the 5d8p state, which voids the simple approximation for constant quantum defects of principle quantum number n.

    A ballistic atom pump is a system containing two reservoirs of neutral atoms or molecules and a junction connecting them containing a localized time-varying potential. Atoms move through the pump as independent particles. Under certain conditions, these pumps can create net transport of atoms from one reservoir to the other. While such systems are sometimes called "quantum pumps," they are also models of classical chaotic transport, and their quantum behavior cannot be understood without study of the corresponding classical behavior. Here we examine classically such a pump's effect on energy and temperature in the reservoirs, in addition to net particle transport. We show that the changes in particle number, of energy in each reservoir, and of temperature in each reservoir vary in unexpected ways as the incident particle energy is varied.

  19. A Combination of the Work Formalism for Exchange with an Optimized Correlation Energy Functional for Atoms

    1995-09-01

    The Harbola-Sahni formalism for the exchange potential of many-electron systems gives extremely accurate total energies for atoms (the energies are practically indistinguishable from the Hartree-Fock energies). We combine here this formalism with the usual density functional prescription for the correlation potential, using a recently developed optimized local correlation functional (Gritsenko O.V. et al., Phys. Rev. A 47 (1993) 1811). Numerical tests carried out for several closed shell atoms and ions indicate that the results preserve the accuracy of the exchange-only calculations. We expect the same behavior to hold true for large molecules and atomic clusters. However, similar tests for the He, Be and Ne isoelectronic series indicate that the optimized local correlation functional is not valid for highly ionized atoms.

  20. Atom probe tomography simulations and density functional theory calculations of bonding energies in Cu3Au

    KAUST Repository

    Boll, Torben

    2012-10-01

    In this article the Cu-Au binding energy in Cu3Au is determined by comparing experimental atom probe tomography (APT) results to simulations. The resulting bonding energy is supported by density functional theory calculations. The APT simulations are based on the Müller-Schottky equation, which is modified to include different atomic neighborhoods and their characteristic bonds. The local environment is considered up to the fifth next nearest neighbors. To compare the experimental with simulated APT data, the AtomVicinity algorithm, which provides statistical information about the positions of the neighboring atoms, is applied. The quality of this information is influenced by the field evaporation behavior of the different species, which is connected to the bonding energies. © Microscopy Society of America 2012.

  3. India's Fertilizer Industry: Productivity and Energy Efficiency

    1999-07-01

    Historical estimates of productivity growth in India's fertilizer sector vary from indicating an improvement to a decline in the sector's productivity. The variance may be traced to the time period of study, source of data for analysis, and type of indices and econometric specifications used for reporting productivity growth. Our analysis shows that in the twenty year period, 1973 to 1993, productivity in the fertilizer sector increased by 2.3% per annum. An econometric analysis reveals that technical progress in India's fertilizer sector has been biased towards the use of energy, while it has been capital and labor saving. The increase in productivity took place during the era of total control when a retention price system and distribution control was in effect. With liberalization of the fertilizer sector and reduction of subsidies productivity declined substantially since the early 1990s. Industrial policies and fiscal incentives still play a major role in the Indian fertilizer sect or. As substantial energy savings and carbon reduction potential exists, energy policies can help overcome barriers to the adoption of these measures in giving proper incentives and correcting distorted prices.

  6. Energy conservation in the primary aluminum and chlor-alkali industries

    Energy Technology Data Exchange (ETDEWEB)

    1980-10-01

    The primary aluminum and chlor-alkali industries together use nearly 13% of the electrical energy consumed by US industry. As part of its mission to promote energy conservation in basic US industries, the DOE surveys the present technological status of the major electrochemical industries and evaluates promising technological innovations that may lead to reduced energy requirements. This study provides technical and economic analyses in support of a government program of research and development in advanced electrolytic technology. This program is intended to supplement the development efforts directed toward energy savings by private industry. Sections II and III of this report cover aluminum and chlorine production processes only, since these two industries represent over 90% of the electrical energy requirements of all electrolytic industries in the United States. Section IV examines barriers to accelerated research and development by the electrolytic industries, and makes suggestions for government actions to overcome these barriers.

  7. The use of atomic spectroscopy in the pharmaceutical industry for the determination of trace elements in pharmaceuticals.

    2011-06-25

    The subject of the analysis of various elements, including metals and metalloids, in the pharmaceutical industry has seen increasing importance in the last 10-15 years, as modern analytical instrumentation has afforded analysts with the opportunity to provide element-specific, accurate and meaningful information related to pharmaceutical products. Armed with toxicological data, compendial and regulatory agencies have revisited traditional approaches to the testing of pharmaceuticals for metals and metalloids, and analysts have begun to employ the techniques of atomic spectroscopy, such as flame- and graphite furnace atomic absorption spectroscopy (FAAS, Flame AA or FAA and GFAAS), inductively coupled plasma-atomic emission spectroscopy (ICP-AES) and inductively coupled plasma-mass spectrometry (ICP-MS), to meet their analytical needs. Newer techniques, such as laser-induced breakdown spectroscopy (LIBS) and Laser Ablation ICP-MS (LAICP-MS) are also beginning to see wider applications in the analysis of elements in the pharmaceutical industry.This article will provide a perspective regarding the various applications of atomic spectroscopy in the analysis of metals and metalloids in drug products, active pharmaceutical ingredients (API's), raw materials and intermediates. The application of atomic spectroscopy in the analysis of metals and metalloids in clinical samples, nutraceutical, metabolism and pharmacokinetic samples will not be addressed in this work.

  8. Energy, industry and politics: Energy, vested interests, and long-term economic growth and development

    Energy Technology Data Exchange (ETDEWEB)

    2010-04-15

    The article seeks to explicate a link between energy and long-term economic growth and development. While in many ways intuitive, attempts at sketching theoretical frameworks explicating this link have been few and simplistic, typically limited to technology and economics. This article emphasizes the importance of politics as well, fostering a symbiosis between the dominant industries of a historical epoch and the energy system that enabled them to flourish. The framework combines Joseph Schumpeter and Mancur Olson, emphasizing 1) the importance of structural economic change for long-term growth and development and 2) vested interests. The framework yields one theoretical proposition: In order to rise, states must prevent vested interests from blocking structural change. States that are unable to do this will get locked into yesterday's technologies, industries and energy systems, effectively consigning themselves to stagnation and decline. A brief empirical section provides historical data from 6 historical epochs (including present-day renewables) over a period of 250 years to demonstrate the usefulness of the approach. While no exhaustive test, the data suggests that countries that have prevented vested interests from blocking change have been far more successful in fostering a symbiosis between energy and industry than those countries that have not.

    This paper describes the outline of the energy efficiency and environmental care policy and management at Siemens Industry Solutions Division. This environmental policy coherently embraces strategic planning, eco-design of energy-efficient industrial processes and solutions, design evaluation and finally communication of both environmental and economic performance of solutions to customers. One of the main tools supporting eco-design and evaluation and controlling of derived design solutions is the so called 'Eco-Care-Matrix' (ECM). The ECM simply visualizes the eco-efficiency of solutions compared to a given baseline. In order to prevent from 'green washing' criticism and to ensure 'walk the talk' attitude the ECM should be scientifically well-founded using appropriate and consistent methodology. The vertical axis of an ECM illustrates the environmental performance and the horizontal axis describes the economical customer benefit of one or more green solutions compared to a defined reference solution. Different scientific approaches for quantifying the environmental performance based on life cycle assessment methodology are discussed especially considering the ISO standards 14040/14044:2006. Appropriate ECM application is illustrated using the example of the Siemens MEROS technology (Maximized Emission Reduction of Sintering) for the steel industry. MEROS is currently the most modern and powerful system for cleaning off-gas in sinter plants. As an environmental technology MEROS is binding and removing sulfur dioxide and other acidic gas components present in the off-gas stream by using dry absorbents and additional electrical power. Advantage in the impact category of acidification potential (by desulfurization) is a trade-off to disadvantages in global warming and resource depletion potential caused by use of electricity. Representing different impacts, indicator results for impact categories with different tendencies have to be

  13. Using Density Functional Theory (DFT) for the Calculation of Atomization Energies

    1995-01-01

    The calculation of atomization energies using density functional theory (DFT), using the B3LYP hybrid functional, is reported. The sensitivity of the atomization energy to basis set is studied and compared with the coupled cluster singles and doubles approach with a perturbational estimate of the triples (CCSD(T)). Merging the B3LYP results with the G2(MP2) approach is also considered. It is found that replacing the geometry optimization and calculation of the zero-point energy by the analogous quantities computed using the B3LYP approach reduces the maximum error in the G2(MP2) approach. In addition to the 55 G2 atomization energies, some results for transition metal containing systems will also be presented.

    2016-01-01

    Over the past decades, strong global demand for industrial chemicals, raw materials and energy has been driven by rapid industrialization and population growth across the world. In this context, long-term environmental sustainability demands the development of sustainable strategies of resource utilization. The agricultural sector is a major source of underutilized or low-value streams that accompany the production of food and other biomass commodities. Animal agriculture in particular constitutes a substantial portion of the overall agricultural sector, with wastes being generated along the supply chain of slaughtering, handling, catering and rendering. The recent emergence of bovine spongiform encephalopathy (BSE) resulted in the elimination of most of the traditional uses of rendered animal meals such as blood meal, meat and bone meal (MBM) as animal feed with significant economic losses for the entire sector. The focus of this review is on the valorization progress achieved on converting protein feedstock into bio-based plastics, flocculants, surfactants and adhesives. The utilization of other rendering streams such as fat and ash rich biomass for the production of renewable fuels, solvents, drop-in chemicals, minerals and fertilizers is also critically reviewed.

    The antiprotonic atom is a three-body exotic system consisting of an antiproton, an electron and a helium nucleus. Its surprising longevity was found and has been studied for more than 10 years. In this work, transition energies and lifetimes of this exotic atom were systematically studied by using the antiproton beam of AD(Antiproton Decelerator) facility at CERN, with an RFQ antiproton decelerator, a narrow-bandwidth laser, Cerenkov counters with fast-response photomultiplier tubes, and cryogenic helium target systems. Thirteen transition energies were determined with precisions of better than 200 ppb by a laser spectroscopy method, together with the elimination of the shift effect caused by collisions with surrounding atoms. Fifteen lifetimes (decay rates) of short-lived states were determined from the time distributions of the antiproton-annihilation signals and the resonance widths of the atomic spectral lines. The relation between the magnitude of the decay rates and the transition multipolarity was inv...

    The elastic network interpolation (ENI) (Kim et al., Biophys J 2002;83:1620-1630) is a computationally efficient and physically realistic method to generate conformational transition intermediates between two forms of a given protein. However it can be asked whether these calculated conformations provide good representatives for these intermediates. In this study, we use ENI to generate conformational transition intermediates between the open form and the closed form of adenylate kinase (AK). Based on C(alpha)-only intermediates, we construct atomic intermediates by grafting all the atoms of known AK structures onto the C(alpha) atoms and then perform CHARMM energy minimization to remove steric conflicts and optimize these intermediate structures. We compare the energy profiles for all intermediates from both the CHARMM force-field and from knowledge-based energy functions. We find that the CHARMM energies can successfully capture the two energy minima representing the open AK and closed AK forms, while the energies computed from the knowledge-based energy functions can detect the local energy minimum representing the closed AK form and show some general features of the transition pathway with a somewhat similar energy profile as the CHARMM energies. The combinatorial extension structural alignment (Shindyalov et al., 1998;11:739-747) and the k-means clustering algorithm are then used to show that known PDB structures closely resemble computed intermediates along the transition pathway.

    Using a unified macroscopic QED formalism, we derive an integral equation for the van der Waals energy of a two-level atomic system near a carbon nanotube. The equation is valid for both strong and weak atom-vacuum-field coupling. By solving it numerically, we demonstrate the inapplicability of weak-coupling-based van der Waals interaction models in a close vicinity of the nanotube surface.

  3. Essays on Industry Response to Energy and Environmental Policy

    Sweeney, Richard Leonard

    This dissertation consists of three essays on the relationship between firm incentives and energy and environmental policy outcomes. Chapters 1 and 2 study the impact of the 1990 Clean Air Act Amendments on the United States oil refining industry. This legislation imposed extensive restrictions on refined petroleum product markets, requiring select end users to purchase new cleaner versions of gasoline and diesel. In Chapter 2, I estimate the static impact of this intervention on refining costs, product prices and consumer welfare. Isolating these effects is complicated by several challenges likely to appear in other regulatory settings, including overlap between regulated and non-regulated markets and deviations from perfect competition. Using a rich database of refinery operations, I estimate a structural model that incorporates each of these dimensions, and then use this cost structure to simulate policy counterfactuals. I find that the policies increased gasoline production costs by 7 cents per gallon and diesel costs by 3 cents per gallon on average, although these costs varied considerably across refineries. As a result of these restrictions, consumers in regulated markets experienced welfare losses on the order of 3.7 billion per year, but this welfare loss was partially offset by gains of 1.5 billion dollars per year among consumers in markets not subject to regulation. The results highlight the importance of accounting for imperfect competition and market spillovers when assessing the cost of environmental regulation. Chapter 2 estimates the sunk costs incurred by United States oil refineries as a result of the low sulfur diesel program. The complex, regionally integrated nature of the industry poses many challenges for estimating these costs. I overcome them by placing the decision to invest in sulfur removal technology within the framework of a two period model and estimate the model using moment inequalities. I find that the regulation induced between 2

    Physisorbed atoms on the surface of interstellar dust grains play a central role in solid state astrochemistry. Their surface reactivity is one source of the observed molecular complexity in space. In experimental astrophysics, the high reactivity of atoms also constitutes an obstacle to measuring two of the fundamental properties in surface physics, namely desorption and diffusion energies, and so far direct measurements are non-existent for O and N atoms. We investigated the diffusion and desorption processes of O and N atoms on cold surfaces in order to give boundary conditions to astrochemical models. Here we propose a new technique for directly measuring the N- and O-atom mass signals. Including the experimental results in a simple model allows us to almost directly derive the desorption and diffusion barriers of N atoms on amorphous solid water ice (ASW) and O atoms on ASW and oxidized graphite. We find a strong constraint on the values of desorption and thermal diffusion energy barriers. The measured b...

    Analyzing the chemical industry's energy use is challenging because of the sector's complexity and the prevailing uncertainty in energy use and production data. We develop an advanced bottom-up model (PIE-Plus) which encompasses the energy use of the 139 most important chemical processes. We apply this model in a case study to analyze the German basic chemical industry's energy use and energy efficiency improvements in the period between 1995 and 2008. We compare our results with data from the German Energy Balances and with data published by the International Energy Agency (IEA). We find that our model covers 88% of the basic chemical industry's total final energy use (including non-energy use) as reported in the German Energy Balances. The observed energy efficiency improvements range between 2.2 and 3.5% per year, i.e., they are on the higher side of the values typically reported in literature. Our results point to uncertainties in the basic chemical industry's final energy use as reported in the energy statistics and the specific energy consumption values. More efforts are required to improve the quality of the national and international energy statistics to make them usable for reliable monitoring of energy efficiency improvements of the chemical industry.

    Risk-based analysis techniques are used to quantify and prioritize a wide variety of problems within the traditional fossil fuel and nuclear power industries. This poster presentation evaluated some of the risk analysis tools and methods used by the energy industry to quantify and manage wind energy development risks. A comprehensive risk-based approach for identifying the probability and consequences of potential concerns was presented for a sample wind energy project. The process determined objectives in relation to the project's net present value. Contributing domains included the energy production, prices, and operating costs of the project. Decision criteria used to evaluate the desirability of the wind project were then developed. Monte Carlo simulations were the used to aggregate individual risks into an overall total. The contribution of each element to the decision objective was calculated separately. The element outputs were than combined into a measure of aggregate risk exposure. Aggregate results were used to calculate the decision criteria. The decision objective was to determine if the energy cost was less than the avoided cost of other project options. The study showed that the approach can allow decision-makers to mitigate risks. However, the results are dependent on the quality of the input data. tabs., figs.

    This chapter addresses past, ongoing, and short (to 2010) and medium-term (to 2030) future actions that can be taken to mitigate GHG emissions from the manufacturing and process industries. Globally, and in most countries, CO{sub 2} accounts for more than 90% of CO{sub 2}-eq GHG emissions from the industrial sector (Price et al., 2006; US EPA, 2006b). These CO{sub 2} emissions arise from three sources: (1) the use of fossil fuels for energy, either directly by industry for heat and power generation or indirectly in the generation of purchased electricity and steam; (2) non-energy uses of fossil fuels in chemical processing and metal smelting; and (3) non-fossil fuel sources, for example cement and lime manufacture. Industrial processes also emit other GHGs, e.g.: (1) Nitrous oxide (N{sub 2}O) is emitted as a byproduct of adipic acid, nitric acid and caprolactam production; (2) HFC-23 is emitted as a byproduct of HCFC-22 production, a refrigerant, and also used in fluoroplastics manufacture; (3) Perfluorocarbons (PFCs) are emitted as byproducts of aluminium smelting and in semiconductor manufacture; (4) Sulphur hexafluoride (SF{sub 6}) is emitted in the manufacture, use and, decommissioning of gas insulated electrical switchgear, during the production of flat screen panels and semiconductors, from magnesium die casting and other industrial applications; (5) Methane (CH{sub 4}) is emitted as a byproduct of some chemical processes; and (6) CH{sub 4} and N{sub 2}O can be emitted by food industry waste streams. Many GHG emission mitigation options have been developed for the industrial sector. They fall into three categories: operating procedures, sector-wide technologies and process-specific technologies. A sampling of these options is discussed in Sections 7.2-7.4. The short- and medium-term potential for and cost of all classes of options are discussed in Section 7.5, barriers to the application of these options are addressed in Section 7.6 and the implication of

    Industrial operations in the United States account for some 37% of the nation's consumptions of energy. It has been estimated that this figure will increase to 50% by 1990 unless appropriate industrial energy conservation measures are adopted. However, such measures are difficult to implement in spite of the potential of various existing, emerging, and advanced technologies that can be applied to the problem. Specifically, the application of many industrial energy conservation measures entails high economic, technological, and institutional risks and uncertainties that constrain industries from adopting such measures. Accordingly, in 1975 the federal government started a program designed to mitigate these risks and uncertainties via government-industry partnership arrangements in the interests of national energy conservation. An important element of this program is the Industrial Energy Conservation Program in the Federal Department of Energy (DOE). In June 1980, DOE asked the National Materials Advisory Board, a unit of the National Academy of Sciences-National Research Council, to form a study committee to assess the effectiveness of the Industrial Energy Conservation Program. The committee concluded that federal support embodied in the DOE program, present and planned, is important to conserving additional industrial energy. However, the committee also concluded that the program needs various improvements in project selection and management and in transfer of results to industry. The committee's findings and recommendations and the results of the deliberation of the committee's three panels, a special report on heat and power, and a report on the visit by four members of the committee to Japan are presented.

    The surface energies for 38 surfaces of fcc metals Cu, Ag, Au, Ni, Pd, Pt, Al, Pb, Rh and Ir have been calculated by using the modified embedded-atom method. The results show that, for Cu, Ag, Ni, Al, Pb and Ir, the average values of the surface energies are very close to the polycrystalline experimental data. For all fcc metals, as predicted, the close-packed (111) surface has the lowest surface energy. The surface energies for the other surfaces increase linearly with increasing angle between the surfaces (hkl) and (111). This can be used to estimate the relative values of the surface energy.

    There is almost no chance to learn about the words (atomic energy), (radioactivity) and (radiation) in the middle and/or high school educations in Japan, because physics is one of the options in the high school curriculum, and 80-90% of students do not like to choose physics. This inquires aim to know the level of their knowledge on energy resources, atomic energy, radioactivity, radiation, and information sources on their related knowledge. Inquiries are made for the middle and high school students in Tokushima and Tsuruga. There are coal power plants in Tokushima, while atomic power plants in Tsuruga. Fossils energy gets the highest points in Tokushima, while Atomic energy gets the highest points in Tsuruga for a present-day energy source. Solar energy sources get the highest point as a promising 21st century energy source in both prefectures, especially for female students. Radioactivity reminds them of words atomic bomb, disease, injury, and harmful, those give very negative images. Radiation reminds them of words roentgen, radiation therapy, x-ray, and hospital use, those designate a sort of plus-image. More than 50 to 60% of them obtained their knowledge from mass media, particularly, television. In addition, less than a few % of them can give any scientific description about these words. As a whole, authors can say that the students have got a certain concept for these words from information of mass media. Meanwhile the school education has approximately no effect on the formation of their concept. Authors are giving some advises and recommendations for the school education and mass media in Japan. (Y.

    The stacking fault energies of five fcc metals (Cu, Ag, Au, Ni and Al) with various quan-tivalences have been calculated by embedded-atom method (EAM). It indicated that the stacking fault energy is mainly determined by the metallic bond-energy and the lattice constant. Thus, monovalent fcc metals should have different stacking fault energies, contrary to Attree’s conclusion. The interaction energy between stacking faults one I 111 I layer apart in a fcc metal is found to be 1/40-1/250 of its self-energy, while it becomes zero when the two stacking faults are two layers apart. The twin energy is just half of the energy of intrinsic stacking fault energy without the consideration of lattice relaxation and the energy of a single intrinsic stacking fault is almost the same as that of extrinsic stacking fault, which are consistent with the results from the calculation of Lennard-Jones force between atoms, but differ from Attree’s result.

    In the past years, scaled energy spectroscopy is under active investigation because this method can simplify the analysis of atomic spectra in the external field based on classic mechanics. A fully computer-controlled experimental system to study the constant scaled-energy spectroscopy was established and described in this paper. The excitation energy E and the strength of the external electric field F were controlled synchronously to keep the scaled-energy epsilon = E/square root of F constant. With this system, constant scaled-energy spectra of Strontium Rydberg atoms at epsilon = -3.0 in a static electric field were successfully recorded for the first time, and the recurrence spectra were obtained by a Fourier transform.

    This paper describes the achievements of a program in which technology education is provided to cultivate practical core engineers for low-level radiation. It was made possible by means of (1) an introductory education program starting at an early age and a continuous agenda throughout college days and (2) regional collaboration. First, with regard to the early-age introductory education program and the continuous education agenda, the subjects of study related to atomic energy or nuclear engineering were reorganized as “Subjects related to Atomic Power Education” for all grades in all departments. These subjects were included in the syllabus and the student guide book, emphasizing a continuous and consistent policy throughout seven-year college study, including the five-year system and additional two-year advanced course. Second, to promote practical education, the contents of lectures, experiments, and internships were enriched and realigned in collaboration with the Japan Atomic Energy Agency, Okayama University and The Cyugoku Electric Power Co., Inc. In addition to the expansion and rearrangement of atomic power education, research on atomic power conducted for graduation thesis projects were undertaken to enhance the educational and research activities. In consequence, it has been estimated that there is now a total of fourteen subject areas in atomic energy technology, more than eight-hundred registered students in the department, and thirteen members of the teaching staff related to atomic energy technology. Furthermore, the “Tsuyama model” is still being developed. This program was funded by the Ministry of Education, Culture, Sports, Science and Technology.

    Full Text Available We propose to conceive an environmental strategy intended to integrate harmoniously Gorj energy industry with principles of sustainable development. The sustainable development complies trinomial: ecological-economic-social. In our view, sustainable development, requires clean water and unpolluted air, land consolidated rejuvenated forests, biodiversity and protected nature reserves, churches and monasteries secular admired by visitors, welcoming places entered in the natural and cultural harmony. It is also necessary to reduce the pressure generated by socio-economic factors on the environment and the principles of sustainable development. The quality of life in urban and rural areas show extreme differences compared to European standards. For efficiency, we addressed the modeling method by designing a model valid for all thermoelectric power plants based on fossil fuels, allowing simultaneously, so adding value and environmental protection. The general objective that we propose for the environment, natural resources and patrimony, is related to the prevention of climate change by limiting the emission of toxic gases and their adverse effects on the environment The achievement of strategic objectives and implementation of proposals submitted, we consider that would have a double impact, on the one side, to protect the environment and the quality of life and, on the other side a positive influence on economic and social level.

    Obtaining accurate power characteristics of ultrasonic treatment systems is an important step towards their industrial scalability. Calorimetric measurements are most commonly used for quantifying the dissipated ultrasonic power. However, accuracy of these measurements is affected by various heat losses, especially when working at high power densities. In this work, electrical power measurements were conducted at all locations in the piezoelectric ultrasonic system equipped with ½″ and ¾″ probes. A set of heat transfer calculations were developed to estimate the convection heat losses from the reaction solution. Chemical dosimeters represented by the oxidation of potassium iodide, Fricke solution and 4-nitrophenol were used to chemically correlate the effect of various electrical amplitudes and treatment regimes. This allowed estimation of sonochemical-efficiency (SE) and energy conversion (XUS) of the ultrasonic system. Results of this study showed overall conversion efficiencies of 60-70%. This correlated well with the chemical dosimeter yield curves of both organic and inorganic aqueous solutions. All dosimeters showed bubble shielding and coalescence effects at higher ultrasonic power levels, less pronounced for the ½″ probe case. SE and XUS values in the range of 10(-10) mol/J and 10(-3) J/J respectively confirmed that conversion of ultrasonic power to chemical yield declined with amplitude.

    Ion beam analysis (IBA) includes a group of techniques for the determination of elemental concentration depth profiles of thin film materials. Often the final results rely on simulations, fits and calculations, made by dedicated codes written for specific techniques. Here we evaluate numerical codes dedicated to the analysis of Rutherford backscattering spectrometry, non-Rutherford elastic backscattering spectrometry, elastic recoil detection analysis and non-resonant nuclear reaction analysis data. Several software packages have been presented and made available to the community. New codes regularly appear, and old codes continue to be used and occasionally updated and expanded. However, those codes have to date not been validated, or even compared to each other. Consequently, IBA practitioners use codes whose validity, correctness and accuracy have never been validated beyond the authors' efforts. In this work, we present the results of an IBA software intercomparison exercise, where seven different packages participated. These were DEPTH, GISA, DataFurnace (NDF), RBX, RUMP, SIMNRA (all analytical codes) and MCERD (a Monte Carlo code). In a first step, a series of simulations were defined, testing different capabilities of the codes, for fixed conditions. In a second step, a set of real experimental data were analysed. The main conclusion is that the codes perform well within the limits of their design, and that the largest differences in the results obtained are due to differences in the fundamental databases used (stopping power and scattering cross section). In particular, spectra can be calculated including Rutherford cross sections with screening, energy resolution convolutions including energy straggling, and pileup effects, with agreement between the codes available at the 0.1% level. This same agreement is also available for the non-RBS techniques. This agreement is not limited to calculation of spectra from particular structures with predetermined

    Full Text Available With the diversified development of coal enterprises in China, the industries related to coal, including coal chemical, electric power, transportation, and building materials, have witnessed rapid development. There is a collaboration relation between the coal industries and most of the aforementioned industries. Based on the synergy theory and the theory of industrial cooperation, the collaboration among coal industries is assessed in this research. Examining China Coal Energy Company as an example, this research divides the compound enterprise system into subsystems such as coal-electric, coal-chemical, and coal-equipment. Next, collaboration indices, including market, scale, and management, are created for each subsystem. Then, the overall collaboration degree of the China Coal Energy Company since it was listed was calculated by standardizing data and estimating the order degree of order parameters and subsystems. Thus, a model measuring the industrial collaboration degree of coal enterprises was established to quantitatively reflect the collaboration degree between various industries. At the same time, the factors influencing the collaboration effect between various industries were analyzed so as to improve this effect, which then can provide a decision basis for enterprises.

    Our main aim in this work is to find out the exact formula of the equilibrium free energy for a cold atom subjected to a harmonic potential in the background of an artificial non-Abelian uniform magnetic field and linearly coupled to a heat bath. The heat bath consists of a collection of independent quantum harmonic oscillators, while its interaction with the cold atom is modeled in terms of bilinear coupling between the coordinate variables of the cold atom and the oscillators. The main thermodynamic properties of such a system are modified in comparison with the Abelian case. For a non-Abelian magnetic field generated from the laser methods employing degenerate dark states, we evaluate the effect of the non-Abelian dynamics on the magnetic moment of the cold atom.

    We propose a computational model for noncontact atomic force microscopy (AFM) in which the atomic force between the cantilever tip and the surface is calculated using a molecular dynamics method, and the macroscopic motion of the cantilever is modeled by an oscillating spring. The movement of atoms in the tip and surface is connected with the oscillating spring using a recently developed coupling method. In this computational model, the oscillation energy is dissipated, as observed in AFM experiments. We attribute this dissipation to the hysteresis and nonconservative properties of the interatomic force that acts between the atoms in the tip and sample surface. The dissipation rate strongly depends on the parameters used in the computational model.

  9. Probing the energy flow in Bessel light beams using atomic photoionization

    The growing interest in twisted light beams also requires a better understanding of their complex internal structure. Particular attention is currently being given to the energy circulation in these beams as usually described by the Poynting vector field. In the present study we propose to use the photoionization of alkali-metal atoms as a probe process to measure (and visualize) the energy flow in twisted light fields. Such measurements are possible since the angular distribution of photoelectrons, emitted from a small atomic target, appears sensitive to and is determined by the local direction of the Poynting vector. To illustrate the feasibility of the proposed method, detailed calculations were performed for the ionization of sodium atoms by nondiffractive Bessel beams.

  10. Hydrogen atom wave function and eigen energy in the Rindler space

    2016-10-01

    We study the hydrogen atom eigenstate energy and wave function in the Rindler space. The probability distribution is tilted because the electric field of the nucleus is no longer spherically symmetric. The hydrogen atom therefore cannot be treated exactly in the same way as what it is in an inertial frame. We also find that if the external force accelerates only the nucleus and then the nucleus accelerates its surrounding electrons through electromagnetic force, the electrons can tunnel through the local energy gap and split the hydrogen atom into an ion. This is similar to what one expects from the Stark effect. However, the critical acceleration is about 3 ×1022 m /s2. It is well beyond the gravitational acceleration on a regular star surface.

    2006-01-01

    The widespread adoption of radioisotopes as tools in biomedical research and therapy became one of the major consequences of the "physicists' war" for postwar life science. Scientists in the Manhattan Project, as part of their efforts to advocate for civilian uses of atomic energy after the war, proposed using infrastructure from the wartime bomb project to develop a government-run radioisotope distribution program. After the Atomic Energy Bill was passed and before the Atomic Energy Commission (AEC) was formally established, the Manhattan Project began shipping isotopes from Oak Ridge. Scientists and physicians put these reactor-produced isotopes to many of the same uses that had been pioneered with cyclotron-generated radioisotopes in the 1930s and early 1940s. The majority of early AEC shipments were radioiodine and radiophosphorus, employed to evaluate thyroid function, diagnose medical disorders, and irradiate tumors. Both researchers and politicians lauded radioisotopes publicly for their potential in curing diseases, particularly cancer. However, isotopes proved less successful than anticipated in treating cancer and more successful in medical diagnostics. On the research side, reactor-generated radioisotopes equipped biologists with new tools to trace molecular transformations from metabolic pathways to ecosystems. The U.S. government's production and promotion of isotopes stimulated their consumption by scientists and physicians (both domestic and abroad), such that in the postwar period isotopes became routine elements of laboratory and clinical use. In the early postwar years, radioisotopes signified the government's commitment to harness the atom for peace, particularly through contributions to biology, medicine, and agriculture.

  13. Kinetic-energy matrix elements for atomic Hylleraas-CI wave functions.

    Harris, Frank E

    2016-05-28

    Hylleraas-CI is a superposition-of-configurations method in which each configuration is constructed from a Slater-type orbital (STO) product to which is appended (linearly) at most one interelectron distance rij. Computations of the kinetic energy for atoms by this method have been difficult due to the lack of formulas expressing these matrix elements for general angular momentum in terms of overlap and potential-energy integrals. It is shown here that a strategic application of angular-momentum theory, including the use of vector spherical harmonics, enables the reduction of all atomic kinetic-energy integrals to overlap and potential-energy matrix elements. The new formulas are validated by showing that they yield correct results for a large number of integrals published by other investigators.

    Eisberg and Resnick present a simple argument for the energy of an electron in a multielectron atom using the concept of shielding from electrons in inner shells. The results of such a treatment are unfortunately confined so as to be out of range of experimental values. Here, the effect of electrons in outer shells is included, and, in the nonrelativistic region, energies are obtained for electrons in the first and second shells in reasonable agreement with experiment.

    Within the scheme of the weakest bound electron potential model theory, the concept of spectral-level-like series is presented by reasonably classifying the Rydberg energy level of atom Al. Based on this concept, the regularities of the Rydberg energy levels are systematically studied. The deviations of the calculated values from the experimental values are generally about several percent of 1 cm, which is of high accuracy.

    Nonferrous metal industries play an important role in China's national economy and are some of the country's largest energy consumers. To better understand the nature of CO(2) emissions from these industries and to further move towards low-carbon development in this industry sector, this study investigates the CO(2) emissions of 12 nonferrous metal industries from 2003 to 2010 based on their life-cycle assessments. It then classifies these industries into four "emission-efficiency" types through cluster analysis. The results show that (1) the industrial economy and energy consumption of China's nonferrous metal industries have grown rapidly, although their recent energy consumption rate shows a declining trend. (2) The copper, aluminum, zinc, lead, and magnesium industries, classified as high-emission industries, are the main contributors of CO(2) emissions. The results have implications for policy decisions that aim to enhance energy efficiency, particularly for promoting the transformation of low-efficiency industries to high-efficiency ones. The study also highlights the important role of policy development in technological innovations, optimization, and upgrades, the reduction of coal proportion in energy consumption, and the advancement of new energy sources.

    With the rapid economic development, energy consumption of China has been the second place in the world next to the USA. Usually, measuring energy consumption intensity or efficiency applies heat unit which is joule per gross domestic production (GDP) or coal equivalent per GDP. However, this measuring approach is only oriented by the conversion coefficient of heat combustion which does not match the real value of the materials during their formation in the ecological system. This study applied emergy analysis to evaluate the energy consumption intensity to fill this gap. Emergy analysis is considered as a bridge between ecological system and economic system, which can evaluate the contribution of ecological products and services as well as the load placed on environmental systems. In this study, emergy indicator for performing energy consumption intensity of primary energy was proposed. Industrial production is assumed as the main contributor of energy consumption compared to primary and tertiary industries. Therefore, this study validated this method by investigating the two industrial case studies which were Dalian Economic Development Area (DEDA) and Fuzhou economic and technological area (FETA), to comparatively study on their energy consumption intensity between the different kinds of industrial systems and investigate the reasons behind the differences. The results show that primary energy consumption (PEC) of DEDA was much higher than that of FETA during 2006 to 2010 and its primary energy consumption ratio (PECR) to total emergy involvement had a dramatically decline from year 2006 to 2010. In the same time, nonrenewable energy of PEC in DEDA was also much higher than that in FETA. The reason was that industrial structure of DEDA was mainly formed by heavy industries like petro-chemistry industry, manufacturing industries, and high energy-intensive industries. However, FETA was formed by electronic business, food industry, and light industries. Although

  9. Energy balance of the global photovoltaic (PV) industry--is the PV industry a net electricity producer?

    Science.gov (United States)

    Dale, Michael; Benson, Sally M

    2013-04-02

    A combination of declining costs and policy measures motivated by greenhouse gas (GHG) emissions reduction and energy security have driven rapid growth in the global installed capacity of solar photovoltaics (PV). This paper develops a number of unique data sets, namely the following: calculation of distribution of global capacity factor for PV deployment; meta-analysis of energy consumption in PV system manufacture and deployment; and documentation of reduction in energetic costs of PV system production. These data are used as input into a new net energy analysis of the global PV industry, as opposed to device level analysis. In addition, the paper introduces a new concept: a model tracking energetic costs of manufacturing and installing PV systems, including balance of system (BOS) components. The model is used to forecast electrical energy requirements to scale up the PV industry and determine the electricity balance of the global PV industry to 2020. Results suggest that the industry was a net consumer of electricity as recently as 2010. However, there is a >50% that in 2012 the PV industry is a net electricity provider and will "pay back" the electrical energy required for its early growth before 2020. Further reducing energetic costs of PV deployment will enable more rapid growth of the PV industry. There is also great potential to increase the capacity factor of PV deployment. These conclusions have a number of implications for R&D and deployment, including the following: monitoring of the energy embodied within PV systems; designing more efficient and durable systems; and deploying PV systems in locations that will achieve high capacity factors.

  10. Discrete Energies of a Weakly Outcoupled Atom Laser Beam Outside the Bose–Einstein Condensate Region

    Directory of Open Access Journals (Sweden)

    Teguh Budi Prayitno

    2014-12-01

    Full Text Available We consider the possibility of a discrete set of energies of a weakly outcoupled atom laser beam to the homogeneous Schrödinger equation with anisotropic harmonic trap in Cartesian coordinates outside the Bose–Einstein condensate region. This treatment is used because working in the cylindrical coordinates is not really possible, even though we implement the cigar-shaped trap case. The Schrödinger equation appears to replace a set of two-coupled Gross– Pitaevskii equations by enabling the weak-coupling assumption. This atom laser can be produced in a simple way that only involves extracting the atoms in a condensate from by using the radio frequency field. We initially present the relation between condensates as sources and atom laser as an output by exploring the previous work of Riou et al. in the case of theoretical work for the propagation of atom laser beams. We also show that even though the discrete energies are obtained by means of an approaching harmonic oscillator, degeneracy is only available in two states because of the anisotropic external potential

  11. DEVELOPMENT OF ATOM-ECONOMICAL CATALYTIC PATHWAYS FOR CONVERSIONS OF SYNGAS TO ENERGY LIQUIDS

    The subject of catalytic syngas conversions to fuels and chemicals is well studied (1--3). But globally, the recent focus is on development of technologies that offer an economical route to desired products (4). Economical transport of natural gas from remote locations and within clathrate hydrates is of continuing interest at Brookhaven National Laboratory (BNL). Under this project, a Liquid Phase Low Temperature (LPLT) concept is being applied to attain highly efficient transformations of natural-gas derived syngas to specific products. Furthermore, a more precise term ``Atom Economy'' has been recently introduced by Trost to describe development of highly efficient homogeneously catalyzed synthesis of organic molecules (5). Taken from reference 5, the term ``Atom Economy'' is defined as maximizing the number of atoms of all raw materials that end up in the product with any other reactant required on in catalytic amount. For application to methane transformations that may involve one or more steps, atom economy of each of these steps is critical. The authors, therefore, consider atom-economy synonymous with overall energy efficiency of a process. This paper describes potential liquid products from catalytic syngas conversions, i.e. gas to liquids (GTL) technologies and process considerations that are necessary for economical transport of natural gas. As such, the present study defines an atom-economical standard to directly compare competing GTL technologies.

    Industrial motor-driven systems consume more than 2194billion kWh annually on a global basis and offer one of the largestopportunities for energy savings. In the United States (US), they accountfor more than 50 percent of all manufacturing electricity use. Incountries with less well-developed consumer economies, the proportion ofelectricity consumed by motors is higher-more than 50 percent ofelectricity used in all sectors in China is attributable to motors.Todate, the energy savings potential from motor-driven systems haveremained largely unrealized worldwide. Both markets and policy makerstend to focus on individual system components, which have a typicalimprovement potential of 2-5 percent versus 20-50 percent for completesystems. Several factors contribute to this situation, most notably thecomplexity of the systems themselves. Determining how to optimize asystem requires a high level of technical skill. In addition, once anenergy efficiency project is completed, the energy savings are often notsustained due to changes in personnel and production processes. Althoughtraining and educational programs in the US, UK, and China to promotesystem optimization have proven effective, these resource-intensiveefforts have only reached a small portion of the market.The same factorsthat make it so challenging to achieve and sustain energy efficiency inmotor-driven systems (complexity, frequent changes) apply to theproduction processes that they support. Yet production processestypically operate within a narrow band of acceptable performance. Theseprocesses are frequently incorporated into ISO 9000/14000 quality andenvironmental management systems, which require regular, independentaudits to maintain ISO certification, an attractive value forinternational trade.This paper presents a new approach to achievingindustrial system efficiency (motors and steam) that will encourageplants to incorporate system energy efficiency into their existing ISOmanagement systems.

    Energy Technology Data Exchange (ETDEWEB)

    1986-11-18

    Geothermal effluent from the Oregon Institute of Technology campus and Merle West Medical Center has been discharged to an open drainage ditch adjacent to the City's College Industrial Park since 1964. Over the past few years there has been increasing concern for conservation and preservation of the geothermal aquifers in Klamath Falls, Oregon. An effective way of improving the energy utilization is to cascade the approximately 130/sup 0/F effluent for heating buildings in the industrial park and disposal of the effluent in an existing injection well. An aquifer stress test was performed using the 1500 foot well in the industrial park. Based on the specific capacity, data indicate that the well is capable of accepting an injection rate of at least 700 gpm of the thermal effluent. A plume of degraded water will develop down-gradient of the well. However, the plume is expected to bypass nearby water supply wells and will have no impact on OIT and MWMC space heating wells.

  14. Effect of external energy on atomic, crystalline and powder characteristics of antimony and bismuth powders

    2009-10-01

    Next to atoms and molecules the powders are the smallest state of matter available in high purities and large quantities. The effect of any external energy on the shape, morphology and structure can thus be studied with relative ease. The present investigation deals with the effect of a non-contact external energy on the powders of antimony and bismuth. The characteristics of powders treated by external energy are compared with the as received powders (control). The average particle sizes, 50 and 99, the sizes below which 99% of the particles are present showed significant increase and decrease indicating that the energy had caused deformation and fracture as if the powders have been subjected to high energy milling. To be able to understand the reasons for these changes the powders are characterized by techniques such as X-ray diffraction (XRD), surface area determination (BET), thermal analytical techniques such as DTA–DTG, DSC–TGA and SDTA and scanning electron microscopy (SEM). The treated powder samples exhibited remarkable changes in the powder characteristics at all structural levels starting from polycrystalline particles, through single crystal to atoms. The external energy had changed the lattice parameters of the unit cell which in turn changed the crystallite size and density. The lattice parameters are then used to compute the weight and effective nuclear charge of the atom which showed significant variation. It is speculated that the external energy is acting on the nucleus through some reversible weak interaction of larger cross section causing changes in the proton to neutron ratios. Thus the effect is felt by all the atoms, and hence the unit cell, single crystal grain and grain boundaries. The stresses generated in turn may have caused deformation or fracture of the weak interfaces such as the crystallite and grain boundaries.

  15. Energy efficiency in energy-intensive industries-an evaluation of the Swedish voluntary agreement PFE

    Stenqvist, C.; Nilsson, L.J. [Environmental and Energy Systems Studies, Department of Technology and Society, Faculty of Engineering, Lund University, P.O. Box 118, 22100 Lund (Sweden)

    2012-05-15

    In this paper, we evaluate the Swedish Programme for improving energy efficiency in energy-intensive industries (PFE). Since 2005, some 100 energy-intensive companies have entered this 5-year voluntary agreement (VA) and been exempted from the EU minimum tax on electricity. In return, each company is required to: conduct an energy audit and analysis; identify and invest in profitable electricity saving measures; implement and certify an energy management system; introduce routines for energy efficient procurement and project planning. For most participants the first programme period was completed in 2009 and available data enables this PFE ex-post evaluation. An impact evaluation compiles and analyse data that the companies have reported to the administrating agency, the Swedish Energy Agency (SEA). This assessment of quantifiable results is complemented by a process-oriented approach that combines studies of policy documents, previous evaluations and personal communication with administrators as well as companies. The bottom-up calculation method distinguishes between gross and net impact. While the SEA estimates a gross impact of 1,450 GW h/year, the net impact consists of an interval between 689 and 1,015 GW h of net annual electricity savings. PFE has effectively and, to a low cost, exceeded the estimated impact of a minimum tax and can thus be judged as successful. A comprehensive evaluation plan could facilitate relevant data gathering in PFE and similar VAs and could, in doing so, improve accuracy and possibly reduce evaluation cost. Such a plan should give weight also to the organisational changes, with potential long-lasting effects, that these programmes are capable of promoting.

    This research program addresses the need to increase the energy efficiency of industrialized housing. Two research centers have responsibility for the program: the Center for Housing Innovation at the University of Oregon and the Florida Solar Energy Center, a research institute of the University of Central Florida. The two organizations provide complementary architectural, systems engineering, and industrial engineering capabilities. In 1989 we worked on these tasks: (1) the formation of a steering committee, (2) the development of a multiyear research plan, (3) analysis of the US industrialized housing industry, (4) assessment of foreign technology, (5) assessment of industrial applications, (6) analysis of computerized design and evaluation tools, and (7) assessment of energy performance of baseline and advanced industrialized housing concepts. The current research program, under the guidance of a steering committee composed of industry and government representatives, focuses on three interdependent concerns -- (1) energy, (2) industrial process, and (3) housing design. Building homes in a factory offers the opportunity to increase energy efficiency through the use of new materials and processes, and to increase the value of these homes by improving the quality of their construction. Housing design strives to ensure that these technically advanced homes are marketable and will meet the needs of the people who will live in them.

Second, this report meets the legal requirement of the Energy Information Administration (EIA) to provide adequate documentation in support of its models. Third, it facilitates continuity in model development by providing documentation from which energy analysts can undertake model enhancements, data updates, and parameter refinements as future projects. The NEMS Industrial Demand Model is a dynamic accounting model, bringing together the disparate industries and uses of energy in those industries, and putting them together in an understandable and cohesive framework. The Industrial Model generates mid-term (up to the year 2015) forecasts of industrial sector energy demand as a component of the NEMS integrated forecasting system. From the NEMS system, the Industrial Model receives fuel prices, employment data, and the value of industrial output. Based on the values of these variables, the Industrial Model passes back to the NEMS system estimates of consumption by fuel types.

    The Pulp and Paper Industry in the United States is one of this country`s most energy intensive industries with energy generally being the second or third largest direct operating expense in mill budgets. As such, the industry has long had an effective energy conservation program and has recorded impressive reductions in energy use. It is also one of the two most capital intensive industries in the United States and has a long capital investment cycle, which can be estimated by various techniques at between 20 and 30 years. This paper discusses the estimated impact of the industry`s energy conservation achievements on long term emission reductions of greenhouse gases and will show how technological changes within the industry have impacted past emission reductions and the prospects for continued progress through emerging technologies. The importance to the global competitiveness of the industry of implementing technological change designed to reduce the emission of greenhouse gases within the industry`s normal investment cycle will also be reviewed.

    The Canadian Industry Program for Energy Conservation (CIPEC) was founded in 1975 as an umbrella organization to oversee partnerships between government and private industry. Its primary objective was to promote energy efficiency within the Canadian industrial sector. This report described the energy efficiency initiatives taken by CIPEC member companies for the year 2005 and highlighted CIPEC's accomplishments in 2006-2007. Several successes achieved by individual companies in various industrial sectors were also documented. Many energy-savings ideas have been implemented as a result of programs and services offered by Natural Resources Canada through CIPEC. This report reviewed the following 7 ideas that can be adapted to fit a variety of operating environments: (1) improve processes, (2) transform employee mindsets, (3) upgrade equipment, (4) adopt new technologies, (5) measure energy performance, (6) rethink facility design, and (7) introduce alternative sources of energy. This report revealed that 2005 was a successful year in terms of the energy efficiency accomplishments of Canadian industry. Energy intensity improved by 1.4 per cent in 2005 compared with 2004, contributing to an average annual improvement in energy intensity of 0.7 per cent since 1990 for all of CIPEC industries. Through CIPEC, the mining, manufacturing and construction sectors have voluntarily met and exceeded annual targets to reduce their energy intensity. Upstream oil and gas companies have implemented projects to reduce greenhouse gas emissions by millions of tonnes and electrical utilities have significantly increased their production of alternative energy. refs., tabs., figs.

    The IAEA is the world's centre for cooperation in the nuclear field. It was set up as the world's ``Atoms for Peace'' organization in 1957 within the United Nations family. The Agency works with its Member States and multiple partners worldwide to promote the safe, secure and peaceful use of nuclear technologies. Three main areas of work underpin the IAEA's mission: Safety and Security, Science and Technology, and Safeguards and Verification. To carry out its mission, the Agency is authorized to encourage and assist research on, and development and practical application of, atomic energy for peaceful uses throughout the world; foster the exchange of scientific and technical information on peaceful uses of atomic energy; and encourage the exchange of training of scientists and experts in the field of peaceful uses of atomic energy. Nowadays, nuclear physics and nuclear technology are applied in a great variety of social areas, such as power production, medical diagnosis and therapies, environmental protection, security control, material tests, food processing, waste treatments, agriculture and artifacts analysis. This presentation will cover the role and practical application of physics at the IAEA, and, in particular, focus on the role physics has, and will play, in nuclear security.

    Surface interaction probabilities are critical parameters that determine the behaviour of low pressure plasmas and so are crucial input parameters for plasma simulations that play a key role in determining their accuracy. However, these parameters are difficult to estimate without in situ measurements. In this work, the role of two prominent surface interaction probabilities, the atomic oxygen recombination coefficient γ O and the thermal energy accommodation coefficient α E in determining the plasma properties of low pressure inductively coupled oxygen plasmas are investigated using two-dimensional fluid-kinetic simulations. These plasmas are the type used for semiconductor processing. It was found that α E plays a crucial role in determining the neutral gas temperature and neutral gas density. Through this dependency, the value of α E also determines a range of other plasma properties such as the atomic oxygen density, the plasma potential, the electron temperature, and ion bombardment energy and neutral-to-ion flux ratio at the wafer holder. The main role of γ O is in determining the atomic oxygen density and flux to the wafer holder along with the neutral-to-ion flux ratio. It was found that the plasma properties are most sensitive to each coefficient when the value of the coefficient is small causing the losses of atomic oxygen and thermal energy to be surface interaction limited rather than transport limited.

    This paper presented a Discrete Event Simulation (DES) model for investigating and improving energy efficiency in vehicle assembly line. The car manufacturing industry is one of the highest energy consuming industries. Using Rockwell Arena DES package; a detailed model was constructed for an actual vehicle assembly plant. The sources of energy considered in this research are electricity and fuel; which are the two main types of energy sources used in a typical vehicle assembly plant. The model depicts the performance measurement for process- specific energy measures of painting, welding, and assembling processes. Sound energy efficiency model within this industry has two-fold advantage: reducing CO2 emission and cost reduction associated with fuel and electricity consumption. The paper starts with an overview of challenges in energy consumption within the facilities of automotive assembly line and highlights the parameters for energy efficiency. The results of the simulation model indicated improvements for energy saving objectives and reduced costs.

    We consider high energy electron scattering by hydrogen atoms in the presence of a laser field of moderate power and higher frequencies. If the field is a superposition of a linearly and a circularly polarized laser beam in a particular configuration, then we can show that circular dichroism in two photon transitions can be observed not only for the differential but also for the integrated cross sections, provided the laser-dressing of the atomic target is treated in second order perturbation theory and the coupling between hydrogenic bound and continuum states is involved.

    Energy is an important cost factor in the U.S iron and steel industry. Energy efficiency improvement is an important way to reduce these costs and to increase predictable earnings, especially in times of high energy price volatility. There are a variety of opportunities available at individual plants in the U.S. iron and steel industry to reduce energy consumption in a cost-effective manner. This Energy Guide discusses energy efficiency practices and energy-efficient technologies that can be implemented at the component, process, facility, and organizational levels. A discussion of the structure, production trends, energy consumption, and greenhouse gas emissions of the iron and steel industry is provided along with a description of the major process technologies used within the industry. Next, a wide variety of energy efficiency measures are described. Many measure descriptions include expected savings in energy and energy-related costs, based on case study data from real-world applications in the steel and related industries worldwide. Typical measure payback periods and references to further information in the technical literature are also provided, when available. The information in this Energy Guide is intended to help energy and plant managers in the U.S. iron and steel industry reduce energy consumption and greenhouse gas emissions in a cost-effective manner while maintaining the quality of products manufactured. Further research on the economics of all measures?and on their applicability to different production practices?is needed to assess their cost effectiveness at individual plants.

    Effective atomic numbers, electron densities of some vitamins (Retinol, Riboflavin, Niacin, Biotin, Folic acid, Cobalamin, Phylloquinone and Flavonoids) composed of C, H, O, N, Co, P and S have been calculated for total and partial photon interactions by the direct method for energy range 1 keV-100 GeV by using WinXCOM and kinetic energy released in matter (Kerma) relative to air is calculated in energy range of 1 keV-20 MeV. Change in effective atomic number and electron density with energy is calculated for all photon interactions. Variation of photon mass attenuation coefficients with energy are shown graphically only for total photon interaction. It is observed that change in mass attenuation coefficient with composition of different chemicals is very large below 100 keV and moderate between 100 keV and 10 MeV and negligible above 10 MeV. Behaviour of vitamins is almost indistinguishable except biotin and cobalamin because of large range of atomic numbers from 1(H) to 16 (S) and 1(H) to 27(Co) respectively. K a value shows a peak due to the photoelectric effect around K-absorption edge of high- Z constituent of compound for biotin and cobalamin.

    An approach, based on the use of the quasiclassical Green's function, is developed for investigating high-energy quantum electrodynamical processes in combined strong laser and atomic fields. Employing an operator technique, we derive the Green's function of the Dirac equation in an arbitrary plane wave and a localized potential. Then, we calculate the total cross section of high-energy electron-positron photoproduction in an atomic field of arbitrary charge number (Bethe-Heitler process) in the presence of a strong laser field. It is shown that the laser field substantially modifies the cross section at already available incoming photon energies and laser parameters. This makes it feasible to observe the analogous effect in a laser field of the Landau-Pomeranchuk-Migdal effect for the Bethe-Heitler process.

    Full Text Available In a year and a half after the events of March 2011, Japan excluded all their nuclear reactors, returning to fossil fuels as a basis in the energy field. The shock associated with nuclear disaster seemed to indicate an ultimate end of Japanese adventure with the atom. The situation has, however, significantly changed during the last several months, and the first nuclear reactor connected again to the electric network, is a proof of the change of the energy policy. The article aims to identify the current state of knowledge on the future of nuclear energy in the Japanese energy sector and adjustments proposed in the future energy mix. At the same time, it is an attempt to analyze the reasons that led the current Government of Prime Minister Abe to take very unpopular decisions to return to nuclear energy.

    The trade-off between risk and rate-of-return in investment evaluations is crucial in assessing the commercial potential of future energy-conservation technologies. The focus of the Industrial Conservation Program at ERDA is to reduce the perceived risks of a given technology to the extent that the private sector will adopt the technology within the normal course of its business operations. These perceived risks may emanate from technical, institutional, or commercial uncertainties, or in many cases they may result merely from a company's or industry's lack of previous experience with a particular technology. Regardless of the source of the risk surrounding a project, the uncertainty it poses to the private sector will serve to inhibit decisions to invest. This study evaluates the treatment of risk in capital investments in certain energy-intensive industries which are the primary targets of ERDA's Industrial Conservation Program. These risks evaluation considerations were placed within a context that includes capital budgeting practices and procedures, organizational considerations, and basic rate-of-return evaluation procedures in the targeted energy-intensive industries (petroleum, chemicals, paper, textiles, cement, food processing, aluminum, steel, glass, and agriculture).

  19. Industrial Energy Management Decision Making for Improved Energy Efficiency—Strategic System Perspectives and Situated Action in Combination

    Directory of Open Access Journals (Sweden)

    Patrik Thollander

    2015-06-01

    Full Text Available Improved industrial energy efficiency is a cornerstone in climate change mitigation. Research results suggest that there is still major untapped potential for improved industrial energy efficiency. The major model used to explain the discrepancy between optimal level of energy efficiency and the current level is the barrier model, e.g., different barriers to energy efficiency inhibit adoption of cost-effective measures. The measures outlined in research and policy action plans are almost exclusively technology-oriented, but great potential for energy efficiency improvements is also found in operational measures. Both technology and operational measures are combined in successful energy management practices. Most research in the field of energy management is grounded in engineering science, and theoretical models on how energy management in industry is carried out are scarce. One way to further develop and improve energy management, both theoretically as well as practically, is to explore how a socio-technical perspective can contribute to this understanding. In this article we will further elaborate this potential of cross-pollinating these fields. The aim of this paper is to relate energy management to two theoretical models, situated action and transaction analysis. We conclude that the current model for energy management systems, the input-output model, is insufficient for understanding in-house industrial energy management practices. By the incorporation of situated action and transaction analysis to the currently used input-output model, an enhanced understanding of the complexity of energy management is gained. It is not possible to find a single energy management solution suitable for any industrial company, but rather the idea is to find a reflexive model that can be adjusted from time to time. An idea for such a reflexive model would contain the structural elements from energy management models with consideration for decisions being

  1. Optical meta-atom for localization of light with quantized energy

    CERN Document Server

    Lannebère, Sylvain

    2015-01-01

    The capacity to confine light into a small region of space is of paramount importance in many areas of modern science. Here, we suggest a mechanism to store a quantized "bit" of light - with a very precise amount of energy - in an open core-shell plasmonic structure ("meta-atom") with a nonlinear optical response. Notwithstanding the trapped light state is embedded in the radiation continuum, its lifetime is not limited by the radiation loss. Interestingly, it is shown that the interplay between the nonlinear response and volume plasmons enables breaking fundamental reciprocity restrictions, and coupling very efficiently an external light source to the meta-atom. The collision of an incident optical pulse with the meta-atom may be used to release the trapped radiation "bit".

    We numerically investigate the dynamics of inward circular finite-energy Airy beams carrying different orbital angular momentum (OAM) numbers in a close-Λ three-level atomic vapor with the electromagnetically induced transparency (EIT) window. We report that due to the EIT induced by the microwave field, the transverse intensity distribution properties of Airy beam can be feasibly manipulated and modulated through adjusting OAM numbers l and the frequency detuning, as well as the propagation distance, in the multi-level atomic systems. What's more, the rotation of the beam also can be observed with different positions in atomic ensembles. The investigation may provide a useful tool for studying particle manipulation, signal processing and propagation in graded-index (GRIN) fibers.

    Many states have implemented ratepayer-funded programs to acquire energy efficiency as a predictable and reliable resource for meeting existing and future energy demand. These programs have become a fixture in many U.S. electricity and natural gas markets as they help postpone or eliminate the need for expensive generation and transmission investments. Industrial energy efficiency (IEE) is an energy efficiency resource that is not only a low cost option for many of these efficiency programs, but offers productivity and competitive benefits to manufacturers as it reduces their energy costs. However, some industrial customers are less enthusiastic about participating in these programs. IEE ratepayer programs suffer low participation by industries across many states today despite a continual increase in energy efficiency program spending across all types of customers, and significant energy efficiency funds can often go unused for industrial customers. This paper provides four detailed case studies of companies that benefited from participation in their utility’s energy efficiency program offerings and highlights the business value brought to them by participation in these programs. The paper is designed both for rate-payer efficiency program administrators interested in improving the attractiveness and effectiveness of industrial efficiency programs for their industrial customers and for industrial customers interested in maximizing the value of participating in efficiency programs.

    In the last years, several policies have been proposed by governments and global institutions in order to improve the efficient use of energy in industries worldwide. However, projects in industrial motor systems require new approach, mainly in decision making area, considering the organizational barriers for energy efficiency. Despite the wide application, multicriteria methods remain unexplored in industrial motor systems until now. This paper proposes a multicriteria model using the PROMETHEE II method, with the aim of ranking alternatives for induction motors replacement. A comparative analysis of the model, applied to a Brazilian industry, has shown that multicriteria analysis presents better performance on energy saving as well as return on investments than single criterion. The paper strongly recommends the dissemination of multicriteria decision aiding as a policy to support the decision makers in industries and to improve energy efficiency in electric motor systems. - Highlights: > Lack of decision model in industrial motor system is the main motivation of the research. > A multicriteria model based on PROMETHEE method is proposed with the aim of supporting the decision makers in industries. > The model can contribute to transpose some barriers within the industries, improving the energy efficiency in industrial motor system.

  5. Visualizing the large-$Z$ scaling of the kinetic energy density of atoms

    2016-01-01

    The scaling of neutral atoms to large $Z$, combining periodicity with a gradual trend to homogeneity, is a fundamental probe of density functional theory, one that has driven recent advances in understanding both the kinetic and exchange-correlation energies. Although research focus is normally upon the scaling of energies, insights can also be gained from energy densities. We visualize the scaling of the positive-definite kinetic energy density (KED) in closed-shell atoms, in comparison to invariant quantities based upon the gradient and Laplacian of the density. We notice a striking fit of the KED within the core of any atom to a gradient expansion using both the gradient and the Laplacian, appearing as an asymptotic limit around which the KED oscillates. The gradient expansion is qualitatively different from that derived from first principles for a slowly-varying electron gas and is correlated with a nonzero Pauli contribution to the KED near the nucleus. We propose and explore orbital-free meta-GGA models...

  8. Spatial assignment of symmetry adapted perturbation theory interaction energy components: The atomic SAPT partition.

    Science.gov (United States)

    Parrish, Robert M; Sherrill, C David

    2014-07-28

    We develop a physically-motivated assignment of symmetry adapted perturbation theory for intermolecular interactions (SAPT) into atom-pairwise contributions (the A-SAPT partition). The basic precept of A-SAPT is that the many-body interaction energy components are computed normally under the formalism of SAPT, following which a spatially-localized two-body quasiparticle interaction is extracted from the many-body interaction terms. For electrostatics and induction source terms, the relevant quasiparticles are atoms, which are obtained in this work through the iterative stockholder analysis (ISA) procedure. For the exchange, induction response, and dispersion terms, the relevant quasiparticles are local occupied orbitals, which are obtained in this work through the Pipek-Mezey procedure. The local orbital atomic charges obtained from ISA additionally allow the terms involving local orbitals to be assigned in an atom-pairwise manner. Further summation over the atoms of one or the other monomer allows for a chemically intuitive visualization of the contribution of each atom and interaction component to the overall noncovalent interaction strength. Herein, we present the intuitive development and mathematical form for A-SAPT applied in the SAPT0 approximation (the A-SAPT0 partition). We also provide an efficient series of algorithms for the computation of the A-SAPT0 partition with essentially the same computational cost as the corresponding SAPT0 decomposition. We probe the sensitivity of the A-SAPT0 partition to the ISA grid and convergence parameter, orbital localization metric, and induction coupling treatment, and recommend a set of practical choices which closes the definition of the A-SAPT0 partition. We demonstrate the utility and computational tractability of the A-SAPT0 partition in the context of side-on cation-π interactions and the intercalation of DNA by proflavine. A-SAPT0 clearly shows the key processes in these complicated noncovalent interactions, in

  10. EU energy-intensive industries and emissions trading: losers becoming winners?

    Energy Technology Data Exchange (ETDEWEB)

    Wettestad, Joergen

    2008-11-15

    The EU Emissions Trading System (ETS) initially treated power producers and energy-intensive industries similarly, despite clear structural differences between these industries regarding pass through of costs and vulnerability to global competition. Hence, the energy-intensive industries could be seen as losing out in the internal distribution. In the January 2008 proposal for a reformed ETS post-2012, a differentiated system was proposed where the energy-intensive industries come out relatively much better. What is the explanation for the change taking place? Although power producers still have a dominant position in the system, the increasing consensus about windfall profits has weakened their standing. Conversely, the energy-intensive industries have become better organised and more active. This balance shift is first and foremost noticeable in several important EU-level stake holder consultation processes. Energy-intensive industries have, however, also successfully utilised the national pathway to exert influence on Brussels policy-making. Finally, growing fear of lax global climate policies and related carbon leakage has strengthened the case of these industries further. The latter dimension indicates that although energy-intensive industries have managed to reduce internal distribution anomalies, external challenges remain. (author). 9 refs

    United States industry consumed 32.5 Quads (34,300 PJ) of energy during 2003, which was 33.1% of total U.S. energy consumption (EIA 2003 Annual Energy Review). The U.S. industrial complex yields valuable goods and products. Through its manufacturing processes as well as its abundant energy consumption, it supports a multi-trillion dollar contribution to the gross domestic product and provides millions of jobs in the U.S. each year. Industry also yields waste products directly through its manufacturing processes and indirectly through its energy consumption. These waste products come in two forms, chemical and thermal. Both forms of waste have residual energy values that are not routinely recovered. Recovering and reusing these waste products may represent a significant opportunity to improve the energy efficiency of the U.S. industrial complex. This report was prepared for the U.S. Department of Energy Industrial Technologies Program (DOE-ITP). It analyzes the opportunity to recover chemical emissions and thermal emissions from U.S. industry. It also analyzes the barriers and pathways to more effectively capitalize on these opportunities. A primary part of this analysis was to characterize the quantity and energy value of the emissions. For example, in 2001, the industrial sector emitted 19% of the U.S. greenhouse gases (GHG) through its industrial processes and emitted 11% of GHG through electricity purchased from off-site utilities. Therefore, industry (not including agriculture) was directly and indirectly responsible for emitting 30% of the U.S. GHG. These emissions were mainly comprised of carbon dioxide (CO2), but also contained a wide-variety of CH4 (methane), CO (carbon monoxide), H2 (hydrogen), NMVOC (non-methane volatile organic compound), and other chemicals. As part of this study, we conducted a survey of publicly available literature to determine the amount of energy embedded in the emissions and to identify technology opportunities to capture and

    This paper describes the following matters on the future images of the energy industries: The following two scenarios may be drawn on the future world order from the changing signs seen in three regions of the geopolitical factors, international economies, and environmental problems : One is the world of mercantilism where several blocks are formed, with the economic power of each block regarded as the ultimate purpose. Trades within a block are executed according to the market principles, while trades between the blocks are operated politically. The energy industries in this case should face incessantly new rules and market restructuring. Another scenario is a coordination maintaining world where international cooperations are preferred to the common benefits. Affluent nations determine the necessity of global systems for trade and environmental problems, while less affluent nations are forced to coordinate with these determinations. In this case, the energy industries will face directly a cost rise associated with conversions to cleaner fuels and industrial restructuring. 8 figs.

    Calculations were performed for the self-diffusion activation energies of monovacancy and both formation and binding energies of divacancies for alkaline metals Li, Na, K, Rb, Cs using the embedded atom method (EAM) model for bcc transition metals developed by the authors recently. The aim of the paper is to extend the application of the new model, to compare the calculated values for self-diffusion with the experimental data and those of previous calculations, and to discuss the intrinsic characteristic of self-diffusion in alkaline metals. The calculated monovacancy migration energies and activation energies are in excellent agreement with experimental data, and the calculated divacancy migration and activation energies are in good agreement with the experimental values available.

    2004-01-12

    This report contains two companion papers about radiological and environmental research that developed out of efforts of the Atomic Energy Commission in the late 1940s and the 1950s. Both papers were written for the Joint U.S.-Russian International Symposium entitled ''History of Atomic Energy Projects in the 1950s--Sociopolitical, Environmental, and Engineering Lessons Learned,'' which was hosted by the International Institute for Applied Systems Analysis in Laxemberg, Austria, in October 1999. Because the proceedings of this symposium were not published, these valuable historic reviews and their references are being documented as a single ORNL report. The first paper, ''U.S. Radioecology Research Programs Initiated in the 1950s,'' written by David Reichle and Stanley Auerbach, deals with the formation of the early radioecological research programs at the U.S. Atomic Energy Commission's nuclear production facilities at the Clinton Engineering Works in Oak Ridge, Tennessee; at the Hanford Plant in Richland, Washington; and at the Savannah River Plant in Georgia. These early radioecology programs were outgrowths of the environmental monitoring programs at each site and eventually developed into the world renowned National Laboratory environmental program sponsored by the Office of Biological and Environmental Research of the U.S. Department of Energy. The original version of the first paper was presented by David Reichle at the symposium. The second paper, ''U.S. Atomic Energy Commission's Environmental Research Programs Established in the 1950s,'' summarizes all the environmental research programs supported by the U.S. Atomic Energy Commission in the 1950s and discusses their present-day legacies. This paper is a modified, expanded version of a paper that was published in September 1997 in a volume commemorating the 50th anniversary symposium of the U.S. Department of Energy's Office of

    We investigate entirely electronic torsional vibrational modes in linear cumulene chains. The carbon nuclei of a cumulene are positioned along the primary axis so they can participate only in transverse and longitudinal motions. However, the interatomic electronic clouds behave as a torsion spring with remarkable torsional stiffness. The collective dynamics of these clouds can be described in terms of electronic vibrational quanta, which we name torsitons. It is shown that the group velocity of the wavepacket of torsitons is much higher than the typical speed of sound, because of the small mass of participating electrons compared to the atomic mass. For the same reason the maximum energy of the torsitons in cumulenes is as high as a few electronvolts, while the minimum possible energy is evaluated as a few hundred wavenumbers and this minimum is associated with asymmetry of zero point atomic vibrations. Molecular systems for experimental evaluation of the predictions are proposed.

    Low energy ions beam often develop periodic patterns on surfaces under normal or off-normal incidence. Formation of such periodic patterns depends on the substrate material, the ion beam parameters, and the processing conditions. Processing conditions introduce unwanted contaminant atoms, which also play strong role in pattern formation by changing the effective sputtering yield of the material. In this work we have analysed the effect of Cu, Fe and Al impurities introduced during low energy Ar{sup +} ion irradiation on HOPG substrate. It is observed that by changing the species of foreign atoms the surface topography changes drastically. The observed surface topography is co-related with the modified sputtering yield of HOPG. Presence of Cu and Fe amplify the effective sputtering yield of HOPG, so that the required threshold for the pattern formation is achieved with the given fluence, whereas Al does not lead to any significant change in the effective yield and hence no pattern formation occurs.

    Full Text Available Global mega trends attract increased resource preservation as well as system efficiency and arouse growing scientific, industrial and public attention, whereas process and technologic developments still lack realisation due to inaccurate knowledge of real process energy demand, associated possible savings and a low inducement for investment. This investigation develops a generally applicable process for energy data collection focussing on material handling systems based on a predefined target model for energy monitoring in order to generate a valid reference model. The introduction of Standardised Energy Consuming Activities (SECA model enables the development of energy based process functions as reference for its implementation to energetic investigations in various industrial applications. Analysing current and target state of energy monitoring in scientific and industrial investigations for logistics shows the developmental deficit of standardisation and realisation in energy monitoring.

    Full Text Available This paper investigates deregulation of electricity market focusing on electricity prices and drivers of demand for electrical energy in industry in Slovenia. The patterns in evolution of real electricity price developments and the three main components of the electricity price are calculated: liberalized market share for purchased electricity price, regulated infrastructure share for use of electricity network grids and mandatory state charges in the sale of electricity (duty, excise duty and value-added tax. To calculate the real value of electricity prices, producer price index of industrial commodities for electricity prices in industry is used as deflator and implicit deflator of gross domestic product for the size of the economy. In the empirical econometric part is used regression analysis for the amount electricity consumption in the industry depending on the real gross domestic product, direct and cross-price elasticity for natural gas prices in the industry. The results confirmed volatility in real electricity price developments with their increasing tendency and the increasing share of different taxes and state charges in the electricity prices for industry. Demand for electrical energy in industry is positively associated with gross domestic product and price of natural gas as substitute for electrical energy in industry use, and negatively associated with prices of electrical energy for industry.

    Full Text Available Abstract Background The reliable prediction of protein tertiary structure from the amino acid sequence remains challenging even for small proteins. We have developed an all-atom free-energy protein forcefield (PFF01 that we could use to fold several small proteins from completely extended conformations. Because the computational cost of de-novo folding studies rises steeply with system size, this approach is unsuitable for structure prediction purposes. We therefore investigate here a low-cost free-energy relaxation protocol for protein structure prediction that combines heuristic methods for model generation with all-atom free-energy relaxation in PFF01. Results We use PFF01 to rank and cluster the conformations for 32 proteins generated by ROSETTA. For 22/10 high-quality/low quality decoy sets we select near-native conformations with an average Cα root mean square deviation of 3.03 Å/6.04 Å. The protocol incorporates an inherent reliability indicator that succeeds for 78% of the decoy sets. In over 90% of these cases near-native conformations are selected from the decoy set. This success rate is rationalized by the quality of the decoys and the selectivity of the PFF01 forcefield, which ranks near-native conformations an average 3.06 standard deviations below that of the relaxed decoys (Z-score. Conclusion All-atom free-energy relaxation with PFF01 emerges as a powerful low-cost approach toward generic de-novo protein structure prediction. The approach can be applied to large all-atom decoy sets of any origin and requires no preexisting structural information to identify the native conformation. The study provides evidence that a large class of proteins may be foldable by PFF01.

    In the exotic atoms where one atomic $1s$ electron is replaced by a $K^{-}$, the strong interaction between the $K^{-}$ and the nucleus introduces an energy shift and broadening of the low-lying kaonic atomic levels which are determined by only the electromagnetic interaction. By performing X-ray spectroscopy for Z=1,2 kaonic atoms, the SIDDHARTA experiment determined with high precision the shift and width for the $1s$ state of $K^{-}p$ and the $2p$ state of kaonic helium-3 and kaonic helium-4. These results provided unique information of the kaon-nucleus interaction in the low energy limit.

    The U.S. concrete industry is the main consumer of U.S.-produced cement. The manufacturing of ready mixed concrete accounts for more than 75% of the U.S. concrete production following the manufacturing of precast concrete and masonry units. The most significant expenditure is the cost of materials accounting for more than 50% of total concrete production costs - cement only accounts for nearly 24%. In 2009, energy costs of the U.S. concrete industry were over $610 million. Hence, energy efficiency improvements along with efficient use of materials without negatively affecting product quality and yield, especially in times of increased fuel and material costs, can significantly reduce production costs and increase competitiveness. The Energy Guide starts with an overview of the U.S. concrete industry’s structure and energy use, a description of the various manufacturing processes, and identification of the major energy consuming areas in the different industry segments. This is followed by a description of general and process related energy- and cost-efficiency measures applicable to the concrete industry. Specific energy and cost savings and a typical payback period are included based on literature and case studies, when available. The Energy Guide intends to provide information on cost reduction opportunities to energy and plant managers in the U.S. concrete industry. Every cost saving opportunity should be assessed carefully prior to implementation in individual plants, as the economics and the potential energy and material savings may differ.

    The pulp and paper industry ranks fourth in terms of energy consumption among industries worldwide. Globally, the pulp and paper industry accounted for approximately 5 percent of total world industrial final energy consumption in 2007, and contributed 2 percent of direct carbon dioxide (CO2) emissions from industry. Worldwide pulp and paper demand and production are projected to increase significantly by 2050, leading to an increase in this industry’s absolute energy use and greenhouse gas (GHG) emissions. Development of new energy-efficiency and GHG mitigation technologies and their deployment in the market will be crucial for the pulp and paper industry’s mid- and long-term climate change mitigation strategies. This report describes the industry’s processes and compiles available information on the energy savings, environmental and other benefits, costs, commercialization status, and references for 36 emerging technologies to reduce the industry’s energy use and GHG emissions. Although studies from around the world identify a variety of sector-specific and cross-cutting energy-efficiency technologies that have already been commercialized for the pulp and paper industry, information is scarce and/or scattered regarding emerging or advanced energy-efficiency and low-carbon technologies that are not yet commercialized. The purpose of this report is to provide engineers, researchers, investors, paper companies, policy makers, and other interested parties with easy access to a well-structured resource of information on these technologies.

    Energy demand has increased continuously due to advancement in technology and living standards of a large section of people resulting in a wide gap between supply and demand. One of the approaches to reduce this gap would be the adoption of measures of energy conservation in general and the efficient use of energy particularly in motor. This paper presents a review of the research activity in the field of efficiency optimization of three-phase induction motor drive. The approach is analyzed and the better option of energy conservation are identified.

    Thermoelectric materials can realize significant energy savings by generating electricity from untapped waste heat. However, the coupling of the thermoelectric parameters unfortunately limits their efficiency and practical applications. Here, a single-layer-based (SLB) composite fabricated from atomically thick single layers was proposed to optimize the thermoelectric parameters fully. Freestanding five-atom-thick Bi(2)Se(3) single layers were first synthesized via a scalable interaction/exfoliation strategy. As revealed by X-ray absorption fine structure spectroscopy and first-principles calculations, surface distortion gives them excellent structural stability and a much increased density of states, resulting in a 2-fold higher electrical conductivity relative to the bulk material. Also, the surface disorder and numerous interfaces in the Bi(2)Se(3) SLB composite allow for effective phonon scattering and decreased thermal conductivity, while the 2D electron gas and energy filtering effect increase the Seebeck coefficient, resulting in an 8-fold higher figure of merit (ZT) relative to the bulk material. This work develops a facile strategy for synthesizing atomically thick single layers and demonstrates their superior ability to optimize the thermoelectric energy harvesting.

    Although atomic stick-slip friction has been extensively studied since its first demonstration on graphite, the physical understanding of this dissipation-dominated phenomenon is still very limited. In this work, we perform molecular dynamics (MD) simulations to study the frictional behavior of a diamond tip sliding over a graphite surface. In contrast to the common wisdom, our MD results suggest that the energy barrier associated lateral sliding (known as energy corrugation) comes not only from interaction between the tip and the top layer of graphite but also from interactions among the deformed atomic layers of graphite. Due to the competition of these two subentries, friction on graphite can be tuned by controlling the relative adhesion of different interfaces. For relatively low tip-graphite adhesion, friction behaves normally and increases with increasing normal load. However, for relatively high tip-graphite adhesion, friction increases unusually with decreasing normal load leading to an effectively negative coefficient of friction, which is consistent with the recent experimental observations on chemically modified graphite. Our results provide a new insight into the physical origins of energy corrugation in atomic scale friction.

    Global health has been an issue of seemingly low political importance in comparison with issues that have direct bearing on countries' national security. Recently, health has experienced a "political revolution" or a rise in political importance. Today, we face substantial global health challenges, from the spread of infectious disease, gaps in basic maternal and child health care, to the globalization of cancer. A recent estimate states that the "overall lifetime risk of developing cancer (both sexes) is expected to rise from more than one in three to one in two by 2015." These issues pose significant threats to international health security. To successfully combat these grave challenges, the international community must embrace and engage in global health diplomacy, defined by scholars Thomas Novotny and Vicanne Adams as a political activity aimed at improving global health, while at the same time maintaining and strengthening international relations. The IAEA (International Atomic Energy Agency) is an international organization with a unique mandate to "accelerate and enlarge the contribution of atomic energy to peace, health, and prosperity throughout the world." This article discusses global health diplomacy, reviews the IAEA's program activities in human health by focusing on radiation medicine and cancer, and the peaceful applications of atomic energy within the context of global health diplomacy.

    The amount of electricity used by the industrial sector in Jordan is an important driver for determining the future energy needs of the country. This paper proposed a model to simulate electricity and energy consumption by industry. The general model approach was based on multivariate regression analysis to provide valuable information regarding energy demands and analysis, and to identify the various factors that influence Jordanian industrial electricity consumption. It was determined that industrial gross output and capacity utilization are the most important variables that drive electricity consumption. The results revealed that the multivariate linear regression model can be used to adequately model the Jordanian industrial electricity consumption with coefficient of determination (R2) and adjusted R2 values of 99.3 and 99.2 per cent, respectively. 19 refs., 4 tabs., 2 figs.

    Gross, Jordan M.

    The energy industry's struggle to attract and retain qualified employees continues to threaten the nation's economy, global competitiveness, and national security. Given the nationwide skills and labor shortage in the energy industry, this study was conducted in response to a need to identify causes of person-environment fit and its effects on engineering students' intentions to work in the energy industry after graduation. Structural equation modeling was used to examine the relationships between student inputs, environmental factors, and career-related outcomes. Two models were compared using data collected from 381 undergraduate engineering students from across the country. Results suggest that students who gained knowledge about professions in the energy industry from participating in an internship or co-op at an energy-related company perceived greater fit with the goals and values of the energy industry. In addition, this study found that students who perceive high levels of fit with the energy industry also have high industry attraction, which directly affects their energy industry pursuit intentions. Overall, this research indicates that high quality internships have the potential to increase students' perceived industry fit, which is closely tied to their career intentions. Outcomes of this study are expected to provide stakeholders with new insights to improve practices within the university-industry environment that will educate, promote, and sustain a strong energy workforce for years to come.

The utilization realizes through the engagement of lithium-bromide absorption heat pumps with various energy characteristics such as the heating coefficient (relative conversion ratio COPhp = 1,15; 1,7; 2,2 and the heating capacity. The latter associates with the converted heat-flow energy utilization variant with the heat-transfer medium heating system scheme (one-, twoand multistage heating. The article considers transition to previously not applied service-water preheating due to the technological acceptance of feeding higher temperature water into the dyeing machine and widening specification of the heattransfer media. The authors adduce variants of internal and external energy use and their evaluation based on the relative energy and exergy characteristics. With results of the thermodynamic analysis of the modernized production effectiveness the researchers prove that alongside with traditional and apparent interior utilization of the energy associated with the stream heat recuperation, it is advisable to widen the range of applied heat-transfer media. The transition to the service water twoand multi-stage preheating is feasible. The study shows that the existing energy supply efficiency extremely low index-numbers improve by one or two degrees. Since they are conditioned, inter alia, by the machinery design, traditional approach to energy supply and heat-medium usage as well as the enterprise whole heating system answering requirements of the bygone era of cheap energy resources. The authors examine the continuous dyeing line modernization options intending considerable investments.

    Three wastewater obtained from different industries were evaluated for the feasibility of hydrogen fermentation. Because of the various components of the wastewater, the characteristics of the hydrogen accumulation were different. Several stages with different hydrogen producing rate were observed during the batch hydrogen fermentation of each wastewater. The obvious hydrogen consumption was observed in the last phase of hydrogen fermentation of the wastewater from the winery. It is similar to the reported hydrogen fermentation characteristic of starch. The wastewater coming from the fructose manufactory has the greatest hydrogen potential nearly 150 L-H{sub 2}/kg-COD. The wastewater from food industry has the lower hydrogen potential of 65 L-H{sub 2}/kg-COD. Some of its compounds were not suitable for hydrogen production. The lowest hydrogen potential was observed in the fermentation of the wastewater from the winery, because hydrogen consumption affects the hydrogen recovery from the wastewater from winery.

    The process by which technology and information related to technology are transferred within industry is explored. Property rights in technology are part of the broader field of intellectual property. The general contours of legal protection for knowledge are explored. The four basic forms of intellectual property - patents, trade secrets (or know-how), trademarks, and copyrights - are covered in varying degrees of depth, depending on their relative applicability to the development of the solar industry. Once this background has been established, the legal aspects of licensing are examined. A license is a legal arrangement whereby a party (licensor) who controls the right to use an idea, invention, etc. shares the right to use the particular intellectual property with someone else (licensee). The advantages and disadvantages of licensing are described from the point of view of potential licensees and licensors. Barriers to licensing are discussed.

    The QED contribution to the energies of the circular (n,l=n-1), 2 ≤ n ≤ 19 transitions have been calculated for several kaonic atoms throughout the periodic table, using the current world average kaon mass. Calculations were done in the framework of the Klein-Gordon equation, with finite nuclear size and all-order Uelhing vacuum polarization corrections, as well as Kallen and Sabry and Wichmann and Kroll corrections. These energy level values are compared with other computed values. The circular transition energies are compared with available measured and theoretical transition energy. Electron screening is evaluated using a Dirac-Fock model for the electronic part of the wave function. The effect of electronic wavefunction correlation is evaluated for the first time.

    Basic concepts from the multi-reference state formalism for determining the functions for the modified embedded atom method (MEAM) are adopted to modeling elemental plutonium (Pu). In the case of elemental Pu, the focus is on the background electron density. Here we utilize a portion of the formalism that determines the structure of the background density necessary to capture correct phase ordering between fcc and ideal hcp crystal structures. The critical information comes from cold curves, that is the energy/volume relationships, for these phases. Practically speaking, the energy difference between these two phases determines the stacking fault energy of the material. At the same time, the simple monoclinic phase of elemental Pu also becomes higher in energy at the equilibrium volume of the fcc phase. The new model is based on first-principles electronic structure calculations and captures the basic phase ordering of those calculations.

    2008-09-01

    Energy is the most important cost factor in the U.S petrochemical industry, defined in this guide as the chemical industry sectors producing large volume basic and intermediate organic chemicals as well as large volume plastics. The sector spent about $10 billion on fuels and electricity in 2004. Energy efficiency improvement is an important way to reduce these costs and to increase predictable earnings, especially in times of high energy price volatility. There are a variety of opportunities available at individual plants in the U.S. petrochemical industry to reduce energy consumption in a cost-effective manner. This Energy Guide discusses energy efficiency practices and energy efficient technologies that can be implemented at the component, process, facility, and organizational levels. A discussion of the trends, structure, and energy consumption characteristics of the petrochemical industry is provided along with a description of the major process technologies used within the industry. Next, a wide variety of energy efficiency measures are described. Many measure descriptions include expected savings in energy and energy-related costs, based on case study data from real-world applications in the petrochemical and related industries worldwide. Typical measure payback periods and references to further information in the technical literature are also provided, when available. The information in this Energy Guide is intended to help energy and plant managers in the U.S. petrochemical industry reduce energy consumption in a cost-effective manner while maintaining the quality of products manufactured. Further research on the economics of all measures--and on their applicability to different production practices--is needed to assess their cost effectiveness at individual plants.

    MicroChannel plates (MCP) detectors are frequently used in space instrumentation for detecting a wide range of radiation and particles. In particular, the capability to detect non-thermal low energy neutral species is crucial for the sensor ELENA (Emitted Low-Energy Neutral Atoms), part of the package SERENA (Search for Exospheric Refilling and Emitted Natural Abundances) on board the BepiColombo mission to Mercury to be launched in 2014. ELENA is a TOF sensor, based on a novel concept ultra-sonic oscillating shutter (Start section)which is operated at frequencies up to 50 kHz; a MCP detector is used as a Stop section. It is aimed to detect neutral atoms in the range 10 eV - 5 keV, within 70° FOV, perpendicular to the S/C orbital plane. ELENA will monitor the emission of neutral atoms from the whole surface of Mercury thanks to the spacecraft motion. The major scientific objectives are the interaction between the environment and the planet, the global particle loss-rate and the remote sensing of the surface properties. In particular, surface release processes are investigated by identifying particles release from the surface, via solar wind-induced ion sputtering (100 eV) as well as Hydrogen back-scattered at hundreds eV. MCP absolute detection efficiency for very low energy neutral atoms (EMEFISTO facility of the Physical Institute of University of Bern (CH), measurements on three different type of MCPs coating have been performed providing the behaviors of MCP detection efficiency in the range 10eV-1keV. Outcomes from such measurements are here discussed.

    2013-06-01

    The chemical industry is a large energy user; but chemical products and technologies also are used in a wide array of energy saving and/or renewable energy applications so the industry has also an energy saving role. The chemical and petrochemical sector is by far the largest industrial energy user, accounting for roughly 10% of total worldwide final energy demand and 7% of global GHG emissions. The International Council of Chemical Associations (ICCA) has partnered with the IEA and DECHEMA (Society for Chemical Engineering and Biotechnology) to describe the path toward further improvements in energy efficiency and GHG reductions in the chemical sector. The roadmap looks at measures needed from the chemical industry, policymakers, investors and academia to press on with catalysis technology and unleash its potential around the globe. The report uncovers findings and best practice opportunities that illustrate how continuous improvements and breakthrough technology options can cut energy use and bring down greenhouse gas (GHG) emission rates. Around 90% of chemical processes involve the use of catalysts – such as added substances that increase the rate of reaction without being consumed by it – and related processes to enhance production efficiency and reduce energy use, thereby curtailing GHG emission levels. This work shows an energy savings potential approaching 13 exajoules (EJ) by 2050 – equivalent to the current annual primary energy use of Germany.
