  1. Liquefied Natural Gas Transfer

    Science.gov (United States)

    1980-01-01

    Chicago Bridge & Iron Company's tanks and associated piping are parts of system for transferring liquefied natural gas from ship to shore and storing it. LNG is a "cryogenic" fluid meaning that it must be contained and transferred at very low temperatures, about 260 degrees below Fahrenheit. Before the LNG can be pumped from the ship to the storage tanks, the two foot diameter transfer pipes must be cooled in order to avoid difficulties associated with sharp differences of temperature between the supercold fluid and relatively warm pipes. Cooldown is accomplished by sending small steady flow of the cryogenic substance through the pipeline; the rate of flow must be precisely controlled or the transfer line will be subjected to undesirable thermal stress.

    This presentation addressed issues facing WestPac Terminals' proposed construction of a liquefied natural gas (LNG) terminal and associated facilities on the Ridley Island on the coast of British Columbia. WestPac Terminals Inc. has expertise in natural gas supply and demand, transportation, LNG and economic optimization. Although a review of proposals for receiving terminals in North America has demonstrated the urgency and attractiveness of LNG imports, west coast terminals are not proceeding, largely due to lack of support by local communities. WestPac's proposal includes a deep enough port to accommodate the largest LNG tankers; a port en route to west coast terminal locations to serve as a transshipment hub; sufficient space for LNG storage tanks and natural gas liquids extraction; sea, rail, air and highway access. Other solutions include selecting locations where communities are pro-development where LNG terminals can provide direct financial benefits to the community, and using existing infrastructure to minimize socio-economic impacts. The advantages of developing LNG at the proposed site were discussed in terms of serving energy markets and provincial benefits. LNG source and cost issues were reviewed along with existing markets and required infrastructure for LNG market development. tabs., figs

    2003-07-01

    This Canadian Standard on the production, storage and handling of liquefied natural gas (LNG) was prepared by the Technical Committee on Liquefied Natural Gas under the jurisdiction of the Steering Committee on Oil and Gas Industry Systems and Materials. It establishes the necessary requirements for the design, installation and safe operation of LNG facilities. The Standard applies to the design, location, construction, operation and maintenance of facilities at any location of the liquefaction of natural gas and for the storage, vaporization, transfer, handling and truck transport of LNG. The training of personnel involved is also included as well as containers for LNG storage, including insulated vacuum systems. It includes non-mandatory guidelines for small LNG facilities but does not apply to the transportation of refrigerants, LNG by rail, marine vessel or pipeline. This latest edition contains changes in working of seismic design requirements and minor editorial changes to several clauses to bring the Standard closer to the US National Fire Protection Association's Committee on Liquefied Natural Gas Standard while maintaining Canadian regulatory requirements. The document is divided into 12 sections including: general requirements; plant site provisions; process equipment; stationary LNG storage containers; vaporization facilities; piping system and components; instrumentation and electrical services; transfer of LNG and refrigerants; fire protection, safety and security; and, operating, maintenance and personnel training. This Standard, like all Canadian Standards, was subject to periodic review and was most recently reaffirmed in 2003. 6 tabs., 6 figs., 3 apps.

    2007-01-01

    Liquefied natural gas (LNG) is making progress with several projects of terminal facilities and liquefaction plants everywhere in the world. This too fast development leads to an increase of costs and delays in the construction of LNG facilities and at the medium term the offer will become unable to meet the demand. Today, the LNG engineering market is living on the 2005-2006 endorsed projects but the turning point will be 2010 when all main projects will be achieved. (J.S.)

  7. Liquefied Natural Gas for Trucks and Buses

    International Nuclear Information System (INIS)

    James Wegrzyn; Michael Gurevich

    2000-01-01

    Liquefied natural gas (LNG) is being developed as a heavy vehicle fuel. The reason for developing LNG is to reduce our dependency on imported oil by eliminating technical and costs barriers associated with its usage. The U.S. Department of Energy (DOE) has a program, currently in its third year, to develop and advance cost-effective technologies for operating and refueling natural gas-fueled heavy vehicles (Class 7-8 trucks). The objectives of the DOE Natural Gas Vehicle Systems Program are to achieve market penetration by reducing vehicle conversion and fuel costs, to increase consumer acceptance by improving the reliability and efficiency, and to improve air quality by reducing tailpipe emissions. One way to reduce fuel costs is to develop new supplies of cheap natural gas. Significant progress is being made towards developing more energy-efficient, low-cost, small-scale natural gas liquefiers for exploiting alternative sources of natural gas such as from landfill and remote gas sites. In particular, the DOE program provides funds for research and development in the areas of; natural gas clean up, LNG production, advanced vehicle onboard storage tanks, improved fuel delivery systems and LNG market strategies. In general, the program seeks to integrate the individual components being developed into complete systems, and then demonstrate the technology to establish technical and economic feasibility. The paper also reviews the importance of cryogenics in designing LNG fuel delivery systems

    As low carbon-emitting fossil fuel, the natural gas is mainly used for power generation and industrial applications. It is also used for heating and cooling in commercial and residential buildings as well as in transport industry. Although the natural gas reaches the end-user mainly through pipelines (if gas is available locally), the liquefied form is the most viable alternative to transport natural gas from far away location to the end user. The economic progress in Asia and other parts of the world creates huge demand for energy (oil, gas and coal). As low carbon-emitting fuel, the demand for gas especially in liquefied form is progressively rising. Having 7th largest shale gas reserve (437 trillion cubic feet recoverable), Australia has become one of the world's major natural gas producers and exporters and is expected to continue a dominating role in the world gas market in foreseeable future. This paper reviews Australia's current gas reserve, industries, markets and LNG production capabilities.

  9. Lightweight Tanks for Storing Liquefied Natural Gas

    Science.gov (United States)

    DeLay, Tom

    2008-01-01

    Single-walled, jacketed aluminum tanks have been conceived for storing liquefied natural gas (LNG) in LNG-fueled motor vehicles. Heretofore, doublewall steel tanks with vacuum between the inner and outer walls have been used for storing LNG. In comparison with the vacuum- insulated steel tanks, the jacketed aluminum tanks weigh less and can be manufactured at lower cost. Costs of using the jacketed aluminum tanks are further reduced in that there is no need for the vacuum pumps heretofore needed to maintain vacuum in the vacuum-insulated tanks.

    2012-01-01

    A storage tank is provided for storing liquefied natural gas on, for example, a motor vehicle such as a bus or truck. The storage tank includes a metal liner vessel encapsulated by a resin-fiber composite layer. A foam insulating layer, including an outer protective layer of epoxy or of a truck liner material, covers the composite layer. A non-conducting protective coating may be painted on the vessel between the composite layer and the vessel so as to inhibit galvanic corrosion.

  11. Liquefied natural gas storage at Ambergate

    1970-08-19

    Ambergate works was planned in 1965-1966 and the decision was taken to install 4 ICI lean gas reformers using natural gas as feedstock, fuel, and enrichment. To cover the possible failure of natural gas supplies, petroleum distillate would be used as alternative feedstock and fuel. The choice for alternative enrichment lay between LPG or LNG. Since LNG would provide peak-on-peak storage facilities for either the East Midlands Board or the Gas Council when conversion was completed--and in the meantime would provide an additional source of LNG for local requirements when temporary LNG installations were used during conversion--agreement was reached with the Gas Council for it to build a 5,000-ton storage installation at Ambergate. The installation consists of 3 major sections: (1) the offloading bay and storage tank; (2) the reliquefaction system; and (3) the export system. The offloading bay and storage tank are for the reception and storage of liquefied Algerian natural gas, delivered to Ambergate by road tanker from the Canvey Is. Terminal. The reliquefaction system is to maintain the necessary storage tank conditions by reliquefying the boil-off natural gas. The export system delivers LNG from the storage tank at high pressure through a vaporization section in the national methane grid.

    In severe seismic environments, tanks for storage of liquefied natural gas may benefit from seismic isolation. As the design accelerations increase, the inner tank undergoes progressively greater demands and may suffer from corner uplift, elephant’s foot buckling, gross sliding, shell thickness requirements beyond what can be reliably welded and, eventually, global uplift. Some of these problems cause extra costs while others make the construction impossible. The seismic environments at which...

  2. Liquefied natural gas : a Canadian perspective : an energy market assessment

    International Nuclear Information System (INIS)

    2009-01-01

    World requirements for energy and natural gas are expected to increase in the near future. This energy market assessment presented an overview of global liquefied natural gas (LNG) supply and demand, and discussed the potential effects that imported LNG may have on Canadian gas markets and energy infrastructure. Regasification projects will double the world's existing LNG receiving capacity by 2015. However, LNG pricing will still be indexed to the price of crude oil and oil products in the future. LNG price differences will affect trading opportunities as well as the flow of LNG between regions. North American LNG facility development will be influenced by outlooks for continental gas supply and demand. Current declines combined with recent increases in United States natural gas production from unconventional gas resources will reduce requirements for LNG in the near future, and may have a significant impact on long-term North American and global LNG requirements. Canada's existing facilities are located competitively with other terminals. 33 figs.

    The objective of this article is to present the structuring of a port directing plan for the liquefied natural gas. In this sense, an integrated approach between the applied logistic and the requested market conditions was used. For the large distances transportation of liquefied natural gas, the marine modal must attain technical requirements that are not usual in the port routine. Apart from the proper dimensioning of the naval fleet in order to maximize the transported load, providing the optimization of the economic distance, the entire port infra-structure is planned for the reception of liquefied natural gas, in order to attend the physical peculiarities as well as security aspects of extreme importance. The selection of the studied local was motivated by the fuel supply shortage suffered by the country, especially in the northeast region, which owns already installed thermal units in need of the fuel supply to be operated.

    2010-01-01

    With the significant economic growth in China, energy related environmental issues become more and more serious. Most of air pollutants are produced by burning coal. In order to achieve a sustainable balance between economic growth and environmental protection, China has been taking measures to expand the role played by natural gas, especially since the beginning of the 21st century. As the liquid form of natural gas, liquefied natural gas (LNG) has also been paid more attention in the country. This paper explores main motives for the fast development of China's LNG industry. An overview of the industry is also described, covering LNG receiving terminals, plants and transportation. Despite a relatively short development history of LNG industry in China, there are many remarkable successes. City-gas supply by LNG is widely applied in many small to medium cities, and LNG vehicles and cold energy utilization are growing rapidly with governmental supports. At the end, the developmental trends of China's LNG industry are introduced. All the discussions show that LNG is strategically important in China's future energy infrastructure. - Research highlights: →Explore main momentums for the fast development of China's LNG industry→Analyze detailedly current states and future prospects of LNG infrastructure in China→Introduce and analyze the wide application of LNG-based gas supply mode in China→Discuss new developmental trends in China's LNG industry

    2015-01-01

    Usually considered to be a simple means for easily transporting natural gas over long distances, liquefied natural gas is rapidly gaining ground as a new maritime fuel. As it seeks to reduce its emissions of pollution and greenhouse gases, the maritime transportation industry is preferring this alternative to liquid petroleum fuels because of its low cost and environmental advantages. Developing this new fuel for maritime and river shipping runs up against several difficulties that, to be solved, call for, among other things, setting up a new supply chain - in which Gaztransport and Technigaz (GTT) wants to find its place

  14. Analysis of temperature and pressure changes in liquefied natural gas (LNG) cryogenic tanks

    2004-10-01

    Liquefied natural gas (LNG) is being developed as a transportation fuel for heavy vehicles such as trucks and transit buses, to lessen the dependency on oil and to reduce greenhouse gas emissions. The LNG stations are properly designed to prevent the venting of natural gas (NG) from LNG tanks, which can cause evaporative greenhouse gas emissions and result in fluctuations of fuel flow and changes of fuel composition. Boil-off is caused by the heat added into the LNG fuel during the storage and fueling. Heat can leak into the LNG fuel through the shell of tank during the storage and through hoses and dispensers during the fueling. Gas from tanks onboard vehicles, when returned to LNG tanks, can add additional heat into the LNG fuel. A thermodynamic and heat transfer model has been developed to analyze different mechanisms of heat leak into the LNG fuel. The evolving of properties and compositions of LNG fuel inside LNG tanks is simulated. The effect of a number of buses fueled each day on the possible total fuel loss rate has been analyzed. It is found that by increasing the number of buses, fueled each day, the total fuel loss rate can be reduced significantly. It is proposed that an electric generator be used to consume the boil-off gas or a liquefier be used to re-liquefy the boil-off gas to reduce the tank pressure and eliminate fuel losses. These approaches can prevent boil-off of natural gas emissions, and reduce the costs of LNG as transportation fuel.

    We describe a stochastic dynamic programming model for maximising the revenue generated by regasification of LNG (liquefied natural gas) from storage tanks at importation terminals in relation to a natural gas spot market. We present three numerical resolution strategies: a posterior optimal strategy, a rolling intrinsic strategy and a full option strategy based on a least-squares Monte Carlo algorithm. We then compare model simulation results to the observed behaviour of three LNG importation terminals in the UK for the period April 2011 to April 2012, and find that there was low correlation between the observed regasification decisions of the operators and those suggested by the three simulated strategies. However, the actions suggested by the model simulations would have generated significantly higher revenues, suggesting that the facilities might have been operated sub-optimally. A further numerical experiment shows that increasing the storage and regasification capacities of a facility can significantly increase the achievable revenue, even without altering the amount of LNG received, by allowing operators more flexibility to defer regasification. - Highlights: • We present a revenue maximisation model for LNG (liquefied natural gas) storage tanks at import terminals. • Three resolution strategies: posterior optimal, rolling intrinsic and full option. • The full option strategy is based on a least-squares Monte Carlo algorithm. • Model simulations show potential for higher revenue in three UK LNG terminals. • Numerical experiments show how storage and regasification capacities affect revenue.

    2014-01-01

    The offshore operation of chemical plant requires the compactness of process equipments due to its harsh environment. A DWC (divided wall column), a compact ternary separator, is a good candidate for distillation process in the offshore operation. In this study the DWC is applied to the offshore FLNG (floating liquefied natural gas) plant, but high utility cost is required in the application because of the large difference of boiling points among feed components. A partially diabatic DWC is proposed for the reduction of the operating cost here, and its design procedure is presented along with performance and economic evaluations and the examination of thermodynamic efficiency as well. The heating duty of the proposed DWC including tray heat transfer is 35% less than that of the conventional system, and the cooling duty is 18% less. The evaluation indicates that some 16% less utility cost is used in the DWC compared with the conventional system, though 7% more investment is required. The exergy loss is reduced by 12%, and the thermodynamic efficiency is improved by 3.3 percentage point over the conventional system. - Highlights: • Diabatic divided wall column for FLNG (floating liquefied natural gas) plant. • Compact column for offshore operation. • 35% less heating duty required. • 16% lower utility necessary. • Exergy loss reduced by 12%

    To guarantee more flexibility and safety in supplying natural gas to the Brazilian market, PETROBRAS designed and constructed two liquefied natural gas (LNG) regasification terminals. These terminals are unprecedented in the world since they are the only ones to use vessels that have been adapted to store LNG and re gasify the product onboard and to adopt the model of transferring LNG from a supply ship to a regasification vessel via cryogenic arms. Due to these different characteristics, TRANSPETRO, the PETROBRAS subsidiary in charge of operating these terminals, had to prepare itself not only to deal with a new product but also to operate terminals that have no counterparts in the world. This article gives an overview of the LNG supply chain and of the new Brazilian LNG Terminals from their conception to the preparation process to operate them. (author)

    An overview is presented of the supply and demand outlook for liquefied natural gas (LNG) in the far east, and the basic elements of an LNG supply project in Japan. Power generation is the primary market for LNG in the far east, due to a preference for energy supply diversity, large undeveloped gas resources, drastic improvements in power generation technology, and environmental advantages of natural gas. India and mainland China represent huge potential markets, and projects are under discussion to bring gas by pipeline from Iran or Qatar to both Pakistan or India. The economics of LNG plant development in Japan, including large ($4 billion for field and plant development) capital costs, long-term contracts, government involvement, and gas prices are discussed. Falling yen/dollar exchange rates have substantially bettered the Japanese economy in terms of gas prices. 11 figs., 2 tabs

  2. Impacts of Imported Liquefied Natural Gas on Residential Appliance Components: Literature Review

    Energy Technology Data Exchange (ETDEWEB)

    Lekov, Alex; Sturges, Andy; Wong-Parodi, Gabrielle

    2009-12-09

    An increasing share of natural gas supplies distributed to residential appliances in the U.S. may come from liquefied natural gas (LNG) imports. The imported gas will be of a higher Wobbe number than domestic gas, and there is concern that it could produce more pollutant emissions at the point of use. This report will review recently undertaken studies, some of which have observed substantial effects on various appliances when operated on different mixtures of imported LNG. While we will summarize findings of major studies, we will not try to characterize broad effects of LNG, but describe how different components of the appliance itself will be affected by imported LNG. This paper considers how the operation of each major component of the gas appliances may be impacted by a switch to LNG, and how this local impact may affect overall safety, performance and pollutant emissions.

  3. An economic evaluation of Peru's liquefied natural gas export policy

    Leung, Leonard; Jenkins, Glenn P.

    2014-01-01

    Peru's Camisea gas fields hold nearly 90% of the country's natural gas reserves. In the 1990s, the government had a policy to prioritize Camisea gas for domestic consumption. The revocation of this policy in the 2000s allowed private developers to export 40% of Camisea's proven reserves, equivalent to one third of Peru's total. This USD 3.9 billion liquefied natural gas (LNG) export project boasts the largest single foreign direct investment in Peru's history. A major component of the financing was granted by international financial institutions on economic grounds. While the project was expected to yield a substantial return to private investors, the export of one third of Peru's total proven natural gas reserves is not in line with its long-term interests. We undertake cost–benefit analyses for a series of scenarios, starting with the project's formative stage in the mid-2000s, and then in 2012, two years after it began its commercial operation. In all cases, Peru does not have sufficient reserves to warrant export, and the economic costs far exceed the benefits. This policy of LNG exports should not have been approved by the government, nor should the loans have been granted by international financial institutions to make it possible. - Highlights: • Peru's Liquefied Natural Gas project is creating an economic loss to the country. • Results of our analyses are robust for all scenarios considered. • The present value of the cost of replacing exported energy far exceeds tax revenue. • Projects cannot be approved based only on immediate benefits. • The potential opportunity costs of projects must be considered

  4. Semi-analytical models of hydroelastic sloshing impact in tanks of liquefied natural gas vessels.

    Science.gov (United States)

    Ten, I; Malenica, Š; Korobkin, A

    2011-07-28

    The present paper deals with the methods for the evaluation of the hydroelastic interactions that appear during the violent sloshing impacts inside the tanks of liquefied natural gas carriers. The complexity of both the fluid flow and the structural behaviour (containment system and ship structure) does not allow for a fully consistent direct approach according to the present state of the art. Several simplifications are thus necessary in order to isolate the most dominant physical aspects and to treat them properly. In this paper, choice was made of semi-analytical modelling for the hydrodynamic part and finite-element modelling for the structural part. Depending on the impact type, different hydrodynamic models are proposed, and the basic principles of hydroelastic coupling are clearly described and validated with respect to the accuracy and convergence of the numerical results.

    2005-01-01

    The new tariff proposals for the use of natural gas transportation networks were transmitted to the French Ministry of economy, finances and industry on October 27, 2004 by the commission of energy regulation. These proposals have been adopted and are the object of three legislative texts: the decree no. 2005-607 from May 27 2005 relative to the tariffing rules, the by-law from May 27, 2005 relative to the definition of balancing areas, and the advice from May 27, 2005 relative to the tariffs of use of natural gas transportation networks. In application of article 7 of the law from January 3, 2003, the implementation of the first tariffs of use of natural gas transportation networks and of liquefied natural gas (LNG) facilities is defined in the decree no. 2004-994 from September 21, 2004. On the main transportation network, the tariffing is of 'input-output' type and does not depend on the distance, while at the regional network scale, the tariffing is linked with the distance. The tariff of use of LNG facilities is the sum of 4 terms: a fixed term applied to each batch unloaded at the methane terminal, a term proportional to the unloaded LNG quantities, a term depending on the duration of use of LNG storage facilities and a term covering the gas consumptions of LNG facilities. This document gathers these different legislative texts with their appendixes. (J.S.)

  9. Improving sustainability of maritime transport through utilization of Liquefied Natural Gas (LNG) for propulsion

    International Nuclear Information System (INIS)

    Burel, Fabio; Taccani, Rodolfo; Zuliani, Nicola

    2013-01-01

    Today, most merchant vessels use Heavy Fuel Oils (HFOs) for ship propulsion. These fuels are cost effective but they produce significant amounts of noxious emissions. In order to comply with International Maritime Organization (IMO) rules, Liquefied Natural Gas (LNG) is becoming an interesting option for merchant ships. The aim of the research presented in this paper is to analyse the economic upturn that can result from the use of LNG as fuel for merchant ships and to assess the effects of its utilization in terms of environmental impact. In the first part of the study, a statistical analysis of maritime traffic is carried out in order to identify which merchant ship types could most benefit from using LNG as fuel for ship propulsion. Traffic data of world ships related to the months of May 2008, 2009 and 2010 are analysed. Roll-on/Roll-off vessels (RoRo) and tanker ships spend most of their sailing time in Emission Control Areas (ECA) consequently appear to be the best candidates for LNG use. In particular, the use of LNG is most profitable for tanker ships in the range of 10,000–60,000 DWT (deadweight). In the second part of the study, operational costs and pollutant emission reduction, following LNG implementation, are calculated for a 33,000 DWT tanker ship. Results show that LNG leads to a reduction of 35% of operational costs and 25% of CO 2 emissions. The possibility of improving energy efficiency on board is analysed considering that combustion gases, produced by LNG, are cleaner, thus simplifying the introduction of exhaust gas heat recovery. Two options are considered: simple heat recovery and heat recovery to drive a turbine (ORC). The results show that it is possible to achieve a reduction in fuel consumption of up to 15%. - Highlights: • Ship propulsion accounts for a large amount of noxious emissions in costal/harbour areas. • Today price differential between fuel oil and natural gas is increasing. • The use of Liquefied Natural Gas as fuel

    International Nuclear Information System (INIS)

    Kim, Dae Yeon; Sung, Tae Hong; Kim, Kyung Chun

    2016-01-01

    The intermediate fluid vaporizer has wide applications in the regasification of LNG (liquefied natural gas). The heat exchanger performance is one of the main contributors to the thermodynamic and cost effectiveness of the entire LNG regasification system. Within the paper, the authors discuss a new concept for a compact heat exchanger with a micro-cellular structure medium to minimize volume and mass and to increase thermal efficiency. Numerical calculations have been conducted to design a metal-foam filled plate heat exchanger and a shell-and-tube heat exchanger using published experimental correlations. The geometry of both heat exchangers was optimized using the conditions of thermolators in LNG regasification systems. The heat transfer and pressure drop performance was predicted to compare the heat exchangers. The results show that the metal-foam plate heat exchanger has the best performance at different channel heights and mass flow rates of fluid. In the optimized configurations, the metal-foam plate heat exchanger has a higher heat transfer rate and lower pressure drop than the shell-and-tube heat exchanger as the mass flow rate of natural gas is increased. - Highlights: • A metal foam heat exchanger is proposed for LNG regasification system. • Comparison was made with a shell and tube heat exchanger. • Heat transfer and pressure drop characteristics were estimated. • The geometry of both heat exchangers is optimized for thermolators. • It can be used as a compact and high performance thermolators.

  14. Explaining experience curves for new energy technologies. A case study of liquefied natural gas

    Many new energy technologies seem to experience a fall in unit price as they mature. In this paper we study the unit price of liquefying natural gas in order to make it transportable by ship to gas power installations all over the world. Our point of departure is the experience curve approach, however unlike many other studies of new energy technologies, we also seek to account for autonomous technological change, scale effects and the effects of upstream competition among technology suppliers. To our surprise we find that upstream competition is by far the most important factor contributing to the fall in unit price. With respect to the natural gas business, this may have implications for the future development in prices as the effect of increased upstream competition is temporary and likely to weaken a lot sooner than effects from learning and technological change. Another more general policy implication, is that while promoting new energy technologies, governments must not forget to pay attention to competition policy. (author)

  15. Operation modes research of liquefied natural gas storages as a part of the ground complexes equipment

    Full Text Available The use of the Liquefied Natural Gas (LNG in the space-rocket equipment is motivated by some advantages. That is why a lot of tests and works are actively carried out now on rocket engines using liquefied natural gas.To provide the engine tests and subsequent rocket complex operation a creation of LNG storages is demanded as a part of ground processing equipment and support for their safe operation conditions.One of LNG danger factor is its low boiling temperature, and also changing the condition, density and LNG boiling temperature at storage due to evaporation of light component, namely methane. At refill of the storages having fuel remains with a new LNG portion these factors can lead to formation of the stratified macro-layers and cause a mode of the intensive mixing that is called "rollover", with almost instant evaporation of LNG big mass and sharp pressure boost, capable to result in the storage distraction with catastrophic effects.The work objectives are formulated such as a technique development for forecasting of the LNG parameters in operating storages including the rollover mode, a comparison of calculated results of the LNG parameters with the experimental data, and a definition of possible recommendations for safe operation of LNG storages as a part of the ground complexes equipment.The paper reviews 12 publications concerning the issues and proceeding processes at operation of LNG storages, including the rollover mode.To verify the reliability of process simulation results in the LNG, represented in models by the binary methane-ethane mixture the calculated values have been compared with the experimental data for a LNG storage mode in the reservoir of a ground test complex.The reliability of developed models of the heat-mass-exchange processes in stratified on density and temperature in LNG storage with emergence of conditions for the rollover mode has been verified by comparing the settlement characteristics to the published

    2018-02-26

    This article is a retrospective analysis of liquefied natural gas development (LNG) in Gladstone, Australia by using the structure of the risk governance framework developed by the International Risk Governance Council (IRGC). Since 2010 the port of Gladstone has undergone extensive expansion to facilitate the increasing coal export as well as the new development of three recently completed LNG facilities. Significant environmental and socio-economic impacts and concerns have occurred as a result of these developments. The overall aim of the article, therefore, is to identify the risk governance deficits that arose and to formulate processes capable of improving similar decision-making problems in the future. The structure of the IRGC framework is followed because it represents a broad analytical approach for considering risk assessment and risk governance in Gladstone in ways that include, but also go beyond, the risk approach of the ISO 31000:2009 standard that was employed at the time. The IRGC risk framework is argued to be a consistent and comprehensive risk governance framework that integrates scientific, economic, social, and cultural aspects and advocates the notion of inclusive risk governance through stakeholder communication and involvement. Key aspects related to risk preassessment, risk appraisal, risk tolerability and acceptability, risk management, and stakeholder communication and involvement are considered. The results indicate that the risk governance deficits include aspects related to (i) the risk matrix methodology, (ii) reflecting uncertainties, (iii) cumulative risks, (iv) the regulatory process, and (v) stakeholder communication and involvement. © 2018 Society for Risk Analysis.

    The effective utilization of the cryogenic exergy associated with liquefied natural gas (LNG) vaporization is important. In this paper, a novel combined power cycle is proposed which utilizes LNG in different ways to enhance the power generation of a power plant. In addition to the direct expansion in the appropriate expander, LNG is used as a low-temperature heat sink for a middle-pressure gas cycle which uses nitrogen as working fluid. Also, LNG is used to cool the inlet air of an open Brayton gas turbine cycle. These measures are accomplished to improve the exergy recovery of LNG. In order to analyze the performance of the system, the influence of several key parameters such as pressure ratio of LNG turbine, ratio of the mass flow rate of LNG to the mass flow rate of air, pressure ratio of different compressors, LNG pressure and inlet pressure of nitrogen compressor, on the thermal efficiency and exergy efficiency of the offered cycle is investigated. Finally, the proposed combined cycle is optimized on the basis of first and second laws of thermodynamics. (orig.)

    This paper examines the development of cooperative strategies between countries exporting Liquefied Natural Gas (LNG) and members of the Gas Exporting Countries Forum (GECF). This economic study focuses specifically on an often-raised scenario: the emergence of a cooperative approach designed with the sole aim of logistic rationalization, and which would not have any effect on LNG prices. We first assess the annual gains that may result from this market-power-free cooperative approach using a simple static transportation model. The numerical results obtained suggest that, in the absence of a gain redistribution policy, this cooperative strategy will probably not be adopted because cooperation would not be a rational move for some exporters. The problem of gain sharing is then formulated using cooperative game theory concepts. Several gain-sharing methods have been studied, including the Shapley value and various nucleolus-inspired concepts. Our results suggest that the choice of a redistribution policy appears relatively restricted. Out of the methods studied, only one - per capita nucleolus - satisfies two key requirements. core belonging and monotonicity (in the aggregate). Lastly, we look at how cooperation may give rise to a coordination cost and try to determine the maximum amount of this cost. In view of the low level of this amount and the relative complexity of the sharing method implemented, we consider that the credibility of a logistic cooperation scenario exempt from market power should be reappraised.

    This paper examines the development of cooperative strategies between 12 countries exporting Liquefied Natural Gas (LNG) and belonging to the Gas Exporting Countries Forum (GECF). This economic study is more specifically focused on a scenario often raised: that of the emergence of a cooperative approach designed with the sole aim of logistic rationalization, and which would not have any effect on LNG prices. As this is a standard transportation problem, we first assess the gains that may result from this cooperative approach using a simple static model calibrated on the year 2007. The numerical results obtained suggest that, in the absence of a gain redistribution policy, this cooperative strategy will probably not be adopted because cooperation would not be a rational move for some exporters. The problem of gain sharing is then formulated using cooperative game theory concepts. Several gain sharing methods have been studied, including the Shapley value and various nucleolus-inspired concepts. Our results suggest that the choice of a redistribution policy appears relatively restricted. Out of the methods studied, only one - the per capita nucleolus - satisfies two key requirements: core belonging and mono-tonicity (in the aggregate). Lastly, coordination costs are considered and we determine the maximum amount that can be tolerated by such a cooperation. In view of the low level of this amount and the relative complexity of the sharing method implemented, we consider that the credibility of a logistic cooperation scenario exempt from market power should be reappraised.

    A group of European gas transportation companies within the European Gas Research Group launched in 2007 the 'MOLAS' Project to provide a software program for the analysis of the Liquefied Natural Gas (LNG) ageing process during ship transportation. This program contains two different modeling approaches: a physical algorithm and an 'intelligent' model. Both models are fed with the same input data, which is composed of the ship characteristics (BOR and capacity), voyage duration, LNG composition, temperature, pressure, and volume occupied by liquid phase at the port of origin, together with pressure at the port of destination. The results obtained are the LNG composition, temperature and liquid volume at the port of destination. Furthermore, the physical model obtains the evolution over time of such variables en route as it is based on unsteady mass balances over the system, while the i-model applies neural networks to obtain regression coefficients from historical data composed only of origin and destination measurements. This paper describes both models and validates them from previous published models and experimental data measured in ENAGAS LNG regasification plants. (author)

    Cryogenic generation is one of the most important ways to utilize cold energy during LNG (liquefied natural gas) regasification. This paper fundamentally investigates LNG cryogenic generation with the Stirling cycle method based on previous studies. A basic process of LNG cryogenic generation with the Stirling cycle was presented initially with seawater and LNG as heat source and heat sink. And its thermodynamic analysis was performed to verify the theoretical feasibility of the Stirling cycle method. The generating capacity, the exergy efficiency and the cold energy utilization efficiency of the basic process were also calculated. Subsequently, the influences of evaporation pressure on net work, equipment performance and comprehensive efficiency of cold energy utilization were discussed and the effect of LNG mass flow as well as the ambient temperature was also studied. Finally an improved process of LNG cryogenic generation with Stirling cycle method combined with an air liquefaction process is proposed as feasibility in improvements of the basic process. - Highlights: • We propose a basic process of LNG cryogenic generation with the Stirling cycle. • Seawater and LNG were applied as heat source and heat sink of the basic process. • The max generating capacity of the basic process is 51 kWh/tLNG. • The max cold energy utilization efficiency of the basic process is 0.56. • We also discussed some feasibilities of optimization of the basic cycle

    The present paper does an experimental and numerical investigation of the hydrodynamic interaction and the response of a single point turret-moored Floating Liquefied Natural Gas (FLNG) system, which is a new type of floating LNG (Liquid Natural Gas) platform that consists of a ship-type FPSO hull equipped with LNG storage tanks and liquefaction plants. In particular, this study focuses on the investigation of the roll response of FLNG hull in free-decay motions, white noise waves and also in irregular waves. Model tests of the FLNG system in 60%H filling condition excited by both white noise waves and irregular waves combined with steady wind and current have been carried out. Response Amplitude Operators (RAOs) and time histories of the responses are obtained for sway, roll and yaw motions. Obvious Low Frequency (LF) components of the roll motions are observed, which may be out of expectation. To facilitate the physical understanding of this phenomenon, we filter the roll motions at the period of 30 s into two parts: the Wave Frequency (WF) motions and the Low Frequency (LF) motions respectively. The results indicate that the LF motions are closely related to the sway and yaw motions. Possible reasons for the presence of the LF motions of roll have been discussed in detail, through the comparison with the sway and yaw motions. As for the numerical part, the simulation of the modeled case is conducted with the help of the software SESAM®. A good agreement between experiments and calculations is reported within the scope of trends. However, the numerical simulations should be further improved for the prediction of the FLNG system in the heading sea.

    The invention relates to an method and a system for offshore production of liquefied natural gas, wherein natural gas is supplied from an underground source to a field installation for gas treatment. The gas is transferred in compressed form from the field installation to an LNG tanker, the transfer taking place via a pipeline surrounded by sea water, and the compressed gas being supplied to a conversion plant which is provided on the LNG tanker and is arranged to convert at least a part of the gas to liquefied form, and the liquefied gas being transferred to storage tanks on board the tanker. When the storage tanks on the LNG tanker are filled up, the pipeline is disconnected from the LNG tanker and connected to another, similar tanker, the pipeline being permanently connected to a submerged buoy which is arranged for introduction and releasable securement in a submerged downwardly open receiving space in the tanker, and which is provided with a swivel unit for transfer of gas under a high pressure. 3 figs.

    The purpose of this paper is to develop a methodology to evaluate the feasibility of using landfill gas (LFG) as a liquefied natural gas (LNG) fuel source for heavy-duty refuse trucks operating on landfills. Using LFG as a vehicle fuel can make the landfills more self-sustaining, reduce their dependence on fossil fuels, and reduce emissions and greenhouse gases. Acrion Technologies Inc. in association with Mack Trucks Inc. developed a technology to generate LNG from LFG using the CO2 WASH process. A successful application of this process was performed at the Eco Complex in Burlington County, PA. During this application two LNG refuse trucks were operated for 600 hr each using LNG produced from gases from the landfill. The methodology developed in this paper can evaluate the feasibility of three LFG options: doing nothing, electricity generation, and producing LNG to fuel refuse trucks. The methodology involved the modeling of several components: LFG generation, energy recovery processes, fleet operations, economic feasibility, and decision-making. The economic feasibility considers factors such as capital, maintenance, operational, and fuel costs, emissions and tax benefits, and the sale of products such as surplus LNG and food-grade carbon dioxide (CO2). Texas was used as a case study. The 96 landfills in Texas were prioritized and 17 landfills were identified that showed potential for converting LFG to LNG for use as a refuse truck fuel. The methodology was applied to a pilot landfill in El Paso, TX. The analysis showed that converting LFG to LNG to fuel refuse trucks proved to be the most feasible option and that the methodology can be applied for any landfill that considers this option.

    Based on a consultation of professional bodies, this blueprint expresses the strong commitment of the French State with economic actors towards an energy transition on the long term, and more particularly concerns the development of LNG (liquefied natural gas) as marine fuel. This objective complies with national and European environmental objectives for the reduction of greenhouse emissions and for a better air quality. This blueprint notably develops two European directives which addresses the sulphur content of marine fuels, and the deployment of an infrastructure for alternative fuels. In its first part, this document states the strong political support to the development of LNG: environmental objectives, existing financial levers for a progressive evolution towards LNG, adaptation of the regulatory framework for a sustainable emergence of a LNG sector, implementation of specific trainings of sea-based and ground-based personnel for the handling of LNG. It sketches the development of LNG for each French coastline (Manche-North Sea, Atlantic, Mediterranean Sea) by analysing the potential demand, and by presenting current projects. Some specific issues related to LNG development are then addressed and discussed: creation of global LNG sectors, inclusion of projects within a trans-national approach, taking of the LNG multimodal reality into account. A set of actions is finally defined: definition of a national framework, stronger support of actors in the search for relevant financing solutions, emergence of harmonized regulatory conditions, implementation of relevant training for LNG handling, support to the implementation of projects which will enable the emergence of a LNG sector for fuel supply in France

  11. The role of Liquefied Natural Gas (LNG) in the European gas market

    Mahan, A.

    2003-06-01

    The purpose of this paper is to discuss the role that Liquefied Natural Gas (LNG) might play in the future EU gas market. LNG imports are not likely to have a place in the Netherlands soon, but they could make an important contribution to the volume and diversity of Europe's gas supplies. An important characteristic of LNG is its inherently high costs, throughout the whole chain, from the wellhead to the market. These costs are considerably higher than the costs of bringing oil to the market. Cost considerations, in combination with the rigidity of the gas market, have led to the use of long-term contracts as a basis for the business, as is the case for the long haul pipeline gas business. Costs have come down considerably and further cost reductions are 'in the pipeline'. While this does not alter the fundamentals of the business it has nonetheless helped to extend the reach of LNG. LNG from the Middle East to Europe has now become economically feasible. The high gas prices of recent years have further fuelled the expansion of the LNG business. Supported by a rapidly growing global economy at the turn of this century, many prospects are under development. The positive economic outlook has seen more speculative positioning in every segment of the LNG chain, while more vertical integration has been industry's response to market liberalisation. The more recent slowdown of the market economies has created a surplus of LNG, which is finding its way onto the markets through short-term and spot transactions. The short-term business will grow over the next few years as more LNG and shipping capacity comes on-stream. However, given underlying high costs and limited flexibility, it should be expected that new projects, currently under consideration, will only be developed on the basis of long-term contracts, thus returning to a balance between supply and demand. For these same reasons, LNG will not likely develop the same the liquidity as that of the oil market. The global

    This paper presents an experimental investigation on the heat transfer characteristics of liquefied natural gas flow boiling in a vertical micro-fin tube. The effect of heat flux, mass flux and inlet pressure on the flow boiling heat transfer coefficients was analyzed. The Kim, Koyama, and two kinds of Wellsandt correlations with different Ftp coefficients were used to predict the flow boiling heat transfer coefficients. The predicted results showed that the Koyama correlation was the most accurate over the range of experimental conditions.

    The invention concerns an method and system for offshore production of liquefied natural gas (LNG), wherein natural gas is supplied from an underground source to a subsea production plant. The gas is transferred under a high pressure directly from the production plant to an LNG tanker through a pipeline underwater causing the temperature of the high pressure gas to be lowered to a desired low temperature. This gas is supplied to a conversion plant provided on the LNG tanker and arranged for converting at least a part of the gas to liquid form, and the liquefied gas is transferred to storage tanks on board the same. When the storage tanks are filled up, the pipeline is disconnected from the LNG tanker and connected to another similar tanker. The pipeline is permanently connected to a submerged buoy which is arranged for introduction and releasable securement in a submerged downwardly open receiving space in the tanker, and which is provided with a swivel unit for transfer of gas under a high pressure. 3 figs.

    Gouwens, C.; Dragosavic, M.

    The large reserves and increasing use of natural gas as a source of energy have resulted in its storage and transport becoming an urgent problem. Since a liquid of the same mass occupies only a fraction of the volume of a gas, it is economical to store natural gas as a liquid. Liquefied natural gas is stored in insulated tanks and also carried by ship at a temperature of -160 C to 170 C. If a serious accident allows the LNG to escape, a gas cloud forms. The results of a possible explosion from such a gas cloud are studied. The development of a leak, escape and evaporation, size and propagation of the gas cloud, the explosive pressures to be expected and the results on the environment are investigated. Damage to buildings is examined making use of the preliminary conclusions of the other sub-projects and especially the explosive pressures.

  17. Economy calculation to determine the optimum plant parameters for peak coverage with stored liquefied natural gas. [In German

    1979-02-08

    The economical supply of natural gas is faced with particular problems due to the considerably fluctuating demand as a result of the greatly varying course of temperature; the infrastructure of the gas distribution of largely fluctuating loads is particularly effected. As the utilization structure deteriorates however, the higher specific gas costs rise. It is hence necessary for gas supply optimization, to extensively adapt the gas bought to the gas sold especially when trying to compare with the import. Storage plays a key role in this. Starting with the annual normal line, mathematical relationships are developed for peak coverage wth liquefied natural gas which however, are set up in such a way that every other peak coverage process can be analyzed according to costs and the parameters optimized. A few selected model cases are treated (gas supply undertakings of various sizes, different gas drawing and supply conditions).

  18. Supply chain management and economic valuation of real options in the natural gas and liquefied natural gas industry

    Wang, Mulan Xiaofeng

    My dissertation concentrates on several aspects of supply chain management and economic valuation of real options in the natural gas and liquefied natural gas (LNG) industry, including gas pipeline transportations, ocean LNG shipping logistics, and downstream storage. Chapter 1 briefly introduces the natural gas and LNG industries, and the topics studied in this thesis. Chapter 2 studies how to value U.S. natural gas pipeline network transport contracts as real options. It is common for natural gas shippers to value and manage contracts by simple adaptations of financial spread option formulas that do not fully account for the implications of the capacity limits and the network structure that distinguish these contracts. In contrast, we show that these operational features can be fully captured and integrated with financial considerations in a fairly easy and managerially significant manner by a model that combines linear programming and simulation. We derive pathwise estimators for the so called deltas and structurally characterize them. We interpret them in a novel fashion as discounted expectations, under a specific weighing distribution, of the amounts of natural gas to be procured/marketed when optimally using pipeline capacity. Based on the actual prices of traded natural gas futures and basis swaps, we show that an enhanced version of the common approach employed in practice can significantly underestimate the true value of natural gas pipeline network capacity. Our model also exhibits promising financial (delta) hedging performance. Thus, this model emerges as an easy to use and useful tool that natural gas shippers can employ to support their valuation and delta hedging decisions concerning natural gas pipeline network transport capacity contracts. Moreover, the insights that follow from our data analysis have broader significance and implications in terms of the management of real options beyond our specific application.

    While recognized standards exist for the systematic safety analysis of potential spills or releases from LNG (Liquefied Natural Gas) storage terminals and facilities on land, no equivalent set of standards or guidance exists for the evaluation of the safety or consequences from LNG spills over water. Heightened security awareness and energy surety issues have increased industry's and the public's attention to these activities. The report reviews several existing studies of LNG spills with respect to their assumptions, inputs, models, and experimental data. Based on this review and further analysis, the report provides guidance on the appropriateness of models, assumptions, and risk management to address public safety and property relative to a potential LNG spill over water.

    Gas hydrates are nonstoichiometric crystalline compounds that belong to the inclusion group known as clathrates. They occur when water molecules attach themselves together through hydrogen bonding and form cavities which can be occupied by a single gas or volatile liquid molecule. Gas hydrates, asphaltenes and waxes are three major threats to flow assurance that must be well assessed by design team uptime. Gas hydrates are also looked upon as a future energy source and as a potential climate hazard. The purpose of this review is to show the chemistry and mechanism of gas hydrate formation, the problems they pose, especially to flow assurance, their system implications, their environmental and economic perspectives with respect to their prospects as storage and transport alternative to the liquefied natural gas technology.

    A supply chain of Liquefied Natural Gas (LNG) is composed by several processes like extraction, purification, liquefaction, storage, transport, regasification and distribution. In all these stages, processes need of energy. The main objective of this work is to quantify the energy consumption, mass loss and exergy destruction occurred throughout the chain. Results show that the process of liquefaction is the largest consumer of energy. Storage and transport by ship are responsible for the bigger mass losses and regasification is the process of larger destruction of exergy. A case study is performed considering a stream of pure methane at the input of a liquefaction plant, and evaluates energy along the chain, ending up at the distribution of NG after its regasification.

    This report is the first of a series dealing with the coordination of ministerial actions in favor of the use of liquefied natural gas (LNG) as marine fuel. Tougher sulfur oxides pollution regulations will lead to the progressive abandonment of heavy fuels in maritime propulsion. LNG can meet the future environmental imperatives but its introduction as marine fuel implies important naval and infrastructure investments. This report presents, first, a summary of the report's recommendations and the aim of this coordination study, and, then, treats more thoroughly of the different coordination aspects: 1 - ship fuels; 2 - LNG's advantages; 3 - the necessary adaptations in France for LNG development as marine fuel (infrastructures, regulation, existing examples, exemptions, European policies); 4 - economical actors involvement, industrial challenges, pilot projects, communication, investments financing and actors coordination

    The LNG (liquefied natural gas) regasification process is a source of cold exergy that is suitable to be recovered to improve the efficiency of thermal power plants. In this paper, an innovative power plant with LNG (liquefied natural gas) exergy utilisation and the capture of CO_2 proceeding from the flue gases is presented. It is characterised by the recovery of LNG cold exergy in a closed Brayton cycle and through direct expansion in an expander coupled to an electrical generator. Moreover, this novel power plant configuration allows CO_2 capture, through an oxy-fuel combustion system and a Rankine cycle that operates with the flue gases themselves and in quasi-critical conditions. The greatest advantage of this plant is that all the recoverable LNG exergy is used to increase the efficiency of the CBC (closed Brayton cycle) and in direct expansion whereas, in other power cycles found in literature that associate LNG regasification and CO_2 capture, part of the LNG exergy is used for condensing flue gas CO_2 for its subsequent capture. As a result, a high efficiency power plant is achieved, exceeding 65%, with almost zero greenhouse gas emissions. - Highlights: • LNG cold exergy can be recovered to improve the efficiency of power plants. • High efficiency power plant with almost zero greenhouse gas emissions. • CO_2 capture through an oxy-fuel combustion system and a Rankine cycle. • Sensitivity analysis of key parameters to evaluate the effect on the efficiency. • The exergy available in the LNG represents 34.79% of the fuel exergy.

    In the determination of the net impact of liquefied natural gas (LNG) on greenhouse gas emissions, life cycle assessments (LCA) of electricity generation have yet to combine the effects of transport distances between exporting and importing countries, country-level infrastructure in importing countries, and the fuel sources displaced in importing countries. To address this, we conduct a LCA of electricity generated from LNG export from British Columbia, Canada with a three-step approach: (1) a review of viable electricity generation markets for LNG, (2) the development of results for greenhouse gas emissions that account for transport to importing nations as well as the infrastructure required for power generation and delivery, and (3) emissions displacement scenarios to test assumptions about what electricity is being displaced in the importing nation. Results show that while the ultimate magnitude of the greenhouse gas emissions associated with natural gas production systems is still unknown, life cycle greenhouse gas emissions depend on country-level infrastructure (specifically, the efficiency of the generation fleet, transmission and distribution losses and LNG ocean transport distances) as well as the assumptions on what is displaced in the domestic electricity generation mix. Exogenous events such as the Fukushima nuclear disaster have unanticipated effects on the emissions displacement results. We highlight national regulations, environmental policies, and multilateral agreements that could play a role in mitigating emissions.

    This study proposes a multi-stage travelling-wave thermoacoustically refrigeration system (TAD-RS) operating at liquefied natural gas temperature, which consists of two thermoacoustic engines (TAE) and one thermoacoustic refrigerator (TAR) in a closed-loop configuration. Three thermoacoustic units connect each other through a resonance tube of small cross-sectional area, achieving “self-matching” for efficient thermoacoustic conversion. Based on the linear thermoacoustic theory, a model of the proposed system has been built by using DeltaEC program to show the acoustic field characteristics and performance. It is shown that with pressurized 5 MPa helium as working gas, the TAEs are able to build a stable and strong acoustic field with a frequency of about 85 Hz. When hot end temperature reaches 923 K, this system can provide about 1410 W cooling power at 110 K with an overall exergy efficiency of 15.5%. This study indicates a great application prospect of TAD-RS in the field of natural gas liquefaction with a large cooling capacity and simple structure.

    The transportation of large quantities of natural gas through long distances has been done more frequently by Liquefied Natural Gas (LNG). The increase of natural gas demand and the distance of major reserves, allied to technological improvements and cost reduction through LNG supply chain, have triggered the expressive increase of LNG world market This paper tries to evaluate the influence that LNG should cause on natural gas world market dynamic, analyzing the tendency of gas to become a world commodity, creating international price references, like oil and its derivates. For this, are shown data as natural gas world reserves, the participation of LNG in natural gas world market and their increase. Furthermore, will be analyzed the interaction between major natural gas reserves and their access to major markets, still considering scheduled LNG projects, the following impacts from their implementation and price arbitrage that should be provoked on natural gas markets.

    2016-11-01

    Full Text Available This study presents the design of a novel boil-off gas (BOG re-liquefaction technology using a BOG recondenser system. The BOG recondenser system targets the liquefied natural gas (LNG bunkering operation, in which the BOG phase transition occurs in a pressure vessel instead of a heat exchanger. The BOG that is generated during LNG bunkering operation is characterized as an intermittent flow with various peak loads. The system was designed to temporarily store the transient BOG inflow, condense it with subcooled LNG and store the condensed liquid. The superiority of the system was verified by comparing it with the most extensively employed conventional re-liquefaction system in terms of consumption energy and via an exergy analysis. Static simulations were conducted for three compositions; the results indicated that the proposed system provided 0 to 6.9% higher efficiencies. The exergy analysis indicates that the useful work of the conventional system is 24.9%, and the useful work of the proposed system is 26.0%. Process dynamic simulations of six cases were also performed to verify the behaviour of the BOG recondenser system. The results show that the pressure of the holdup in the recondenser vessel increased during the BOG inflow mode and decreased during the initialization mode. The maximum pressure of one of the bunkering cases was 3.45 bar. The system encountered a challenge during repetitive operations due to overpressurizing of the BOG recondenser vessel.

  12. Natural convection along a heated vertical plate immersed in a nonlinearly stratified medium: application to liquefied gas storage

    Science.gov (United States)

    Forestier, M.; Haldenwang, P.

    We consider free convection driven by a heated vertical plate immersed in a nonlinearly stratified medium. The plate supplies a uniform horizontal heat flux to a fluid, the bulk of which has a stable stratification, characterized by a non-uniform vertical temperature gradient. This gradient is assumed to have a typical length scale of variation, denoted Z0, while 0, and the physical properties of the medium.We then apply the new theory to the natural convection affecting the vapour phase in a liquefied pure gas tank (e.g. the cryogenic storage of hydrogen). It is assumed that the cylindrical storage tank is subject to a constant uniform heat flux on its lateral and top walls. We are interested in the vapour motion above a residual layer of liquid in equilibrium with the vapour. High-precision axisymmetric numerical computations show that the flow remains steady for a large range of parameters, and that a bulk stratification characterized by a quadratic temperature profile is undoubtedly present. The application of the theory permits a comparison of the numerical and analytic results, showing that the theory satisfactorily predicts the primary dynamical and thermal properties of the storage tank.

    LNG (liquefied natural gas) delivered by means of sea-ships is pressurized and then regasified before its introduction to the system of pipelines. The utilization of cryogenic exergy of LNG for electricity production without combustion of any its portion is analyzed. For the conversion of LNG cryogenic exergy into electricity, the Stirling engine is proposed to be applied. The theoretical thermodynamic model of Stirling engine has been applied. This model is used to investigate the influence of pinch temperature in heat exchangers, engine compression ratio and dead volumes ratios on the thermodynamic parameters of the Stirling engine. The results of simulation represent the input data for investigations of thermodynamic performance of the proposed system. In order to evaluate the thermodynamic performance of the proposed process, an exergy analysis has been applied. The exergy efficiency and influence of design and operational parameters on exergy losses are determined for each of the proposed system configurations. The obtained results represent the background for advanced exergy-based analyses, including thermo-ecological cost. - Highlights: • Application of Stirling engine in LNG regasification. • Thermodynamic model of Stirling engine for cryogenic exergy recovery is applied. • Sensitivity analysis of operational parameters on system behaviour is applied. • Exergy analysis is conducted.

  14. Hydrogen production by steam reforming of liquefied natural gas over a nickel catalyst supported on mesoporous alumina xerogel

    Seo, Jeong Gil; Youn, Min Hye; Cho, Kyung Min; Park, Sunyoung; Song, In Kyu

    Mesoporous alumina xerogel (A-SG) is prepared by a sol-gel method for use as a support for a nickel catalyst. The Ni/A-SG catalyst is then prepared by an impregnation method, and is applied to hydrogen production by steam reforming of liquefied natural gas (LNG). The effect of the mesoporous alumina xerogel support on the catalytic performance of Ni/A-SG catalyst is investigated. For the purpose of comparison, a nickel catalyst supported on commercial alumina (A-C) is also prepared by an impregnation method (Ni/A-C). Both the hydroxyl-rich surface and the electron-deficient sites of the A-SG support enhance the dispersion of the nickel species on the support during the calcination step. The formation of the surface nickel aluminate phase in the Ni/A-SG catalyst remarkably increases the reducibility and stability of the catalyst. Furthermore, the high-surface area and the well-developed mesoporosity of the Ni/A-SG catalyst enhance the gasification of surface hydrocarbons that are adsorbed in the reaction. In the steam reforming of LNG, the Ni/A-SG catalyst exhibits a better catalytic performance than the Ni/A-C catalyst in terms of LNG conversion and hydrogen production. Moreover, the Ni/A-SG catalyst shows strong resistance toward catalyst deactivation.

    For historical reasons, the liquefaction of natural gas is performed with onshore equipments and LNG tanker-ships are loaded and unloaded using rigid articulated arms. When these operations are performed in harbors, the movement of the ship with respect to the pier are relatively limited. Today, several companies aim at liquefying natural gas using floating facilities. The loading of tanker-ships is performed offshore, and thus movements between the ship and the floating facility are enhanced. The use of a flexible pipe can be an interesting alternative solution to the articulated arm. This article describes the state-of-the-art of the LNG flexible technology developed by Coflexip Stena Offshore and the progress of the program of development of a cryogenic flexible: structure, fittings, safety (leaks detection), thermal calculations, optimization of the corrugated hose profile, pressure drops, fatigue tests and service life, materials development, prototype and real tests.

    This document, issued by the French Ministry of Economy, Finances and Industry, presents national measures fostering alternative vehicles, i.e., electric, natural gas and liquefied oil gas vehicles. Financial supports for studies aiming at optimizing the fleet and choosing the alternative vehicles as well as for purchasing vehicles both by counter procedure and for demonstration programmes are provided. Amount of subsidies, conditions of obtaining and categories of addressees are indicated. The document contains also two relating studies. The first one is titled 'the policy of developing alternative vehicles'. The following four items are addressed: - the present frame favouring the alternative vehicles; - the electric vehicles; - natural gas fuelled vehicles (GNV); - liquefied oil gas fuelled vehicles (GPLc). Although non-polluting the electric vehicles are not tempting because of their rather limited range (80 Km at a battery charging). So far only around 3,000 vehicles were sold. Fifty GNV buses were ordered by RATP and the figure raised at 70 in 1998 and 1999. The GPLc fleet amounts up to 70,000 vehicles and by the end of 2000 it is foreseen to reach the level of 300,000 vehicles. The second study addresses to the issue of natural gas for vehicles. It presents: - its advantages; - its peculiarities; - the action of public authorities; -the current state and trends of GNV vehicles. In a joint effort public authorities and partners of this option are aiming at a fleet of 2500 light service vehicles and 300 bus for urban transport by the end of 1999.

  20. Life cycle greenhouse gas emissions from U.S. liquefied natural gas exports: implications for end uses.

    2015-03-03

    This study analyzes how incremental U.S. liquefied natural gas (LNG) exports affect global greenhouse gas (GHG) emissions. We find that exported U.S. LNG has mean precombustion emissions of 37 g CO2-equiv/MJ when regasified in Europe and Asia. Shipping emissions of LNG exported from U.S. ports to Asian and European markets account for only 3.5-5.5% of precombustion life cycle emissions, hence shipping distance is not a major driver of GHGs. A scenario-based analysis addressing how potential end uses (electricity and industrial heating) and displacement of existing fuels (coal and Russian natural gas) affect GHG emissions shows the mean emissions for electricity generation using U.S. exported LNG were 655 g CO2-equiv/kWh (with a 90% confidence interval of 562-770), an 11% increase over U.S. natural gas electricity generation. Mean emissions from industrial heating were 104 g CO2-equiv/MJ (90% CI: 87-123). By displacing coal, LNG saves 550 g CO2-equiv per kWh of electricity and 20 g per MJ of heat. LNG saves GHGs under upstream fugitive emissions rates up to 9% and 5% for electricity and heating, respectively. GHG reductions were found if Russian pipeline natural gas was displaced for electricity and heating use regardless of GWP, as long as U.S. fugitive emission rates remain below the estimated 5-7% rate of Russian gas. However, from a country specific carbon accounting perspective, there is an imbalance in accrued social costs and benefits. Assuming a mean social cost of carbon of $49/metric ton, mean global savings from U.S. LNG displacement of coal for electricity generation are $1.50 per thousand cubic feet (Mcf) of gaseous natural gas exported as LNG ($.028/kWh). Conversely, the U.S. carbon cost of exporting the LNG is $1.80/Mcf ($.013/kWh), or $0.50-$5.50/Mcf across the range of potential discount rates. This spatial shift in embodied carbon emissions is important to consider in national interest estimates for LNG exports.

  1. Effluent Mixing Modeling for Liquefied Natural Gas Outfalls in a Coastal Ecosystem

    Directory of Open Access Journals (Sweden)

    2014-06-01

    Full Text Available Liquid Natural Gas (LNG processing facilities typically are located on ocean shores for easy transport of LNG by marine vessels. These plants use large quantities of water for various process streams. The combined wastewater effluents from the LNG plants are discharged to the coastal and marine environments typically through submarine outfalls. Proper disposal of effluents from an LNG plant is essential to retain local and regional environmental values and to ensure regulatory and permit compliance for industrial effluents. Typical outfall designs involve multi-port diffuser systems where the design forms a part of the overall environmental impact assessment for the plant. The design approach needs to ensure that both near-field plume dispersion and far-field effluent circulation meets the specified mixing zone criteria. This paper describes typical wastewater process streams from an LNG plant and presents a diffuser system design case study (for an undisclosed project location in a meso-tidal coast to meet the effluent mixing zone criteria. The outfall is located in a coastal and marine ecosystem where the large tidal range and persistent surface wind govern conditions for the diffuser design. Physical environmental attributes and permit compliance criteria are discussed in a generic format. The paper describes the design approach, conceptualization of numerical model schemes for near- and far-field effluent mixing zones, and the selected diffuser design.

    2013-01-01

    Due to a good behavior of ammonia-water during the two-phase heat addition process and the liquefied natural gas with great cold energy, an ammonia-water power system with LNG as its heat sink is proposed to utilize the low grade waste heat. Based on the thermodynamic mathematical models, the effects of key thermodynamic design parameters, including turbine inlet pressure, turbine inlet temperature, ammonia mass fraction, pinch temperature difference and approach temperature difference in the heat recovery vapor generator, on the system performance are examined from the view of both thermodynamics and economics. To obtain the optimum performance, multi-objective optimization is conducted to find the best thermodynamic design parameters from both thermodynamic and economic aspects using NSGA-II (Non-dominated sorting genetic algorithm-II). The exergy efficiency, total heat transfer capability and turbine size parameter are selected as three objective functions to maximize the exergy efficiency, and minimize the total heat transfer capability and turbine size parameter under the given waste heat conditions. The results show that turbine inlet pressure, turbine inlet temperature, ammonia mass fraction, pinch temperature difference and approach temperature difference have significant effects on the system performance. By multi-objective optimization, the Pareto frontier solution for the ammonia-water power system is obtained. - Highlights: ► An ammonia-water power system with LNG as its heat sink is proposed. ► The effects of key parameters on the system performance are examined. ► Multi-objective optimization is conducted to obtain optimum system performance

    Spill and combustion of a pool as a result of a spreading of liquefied natural gas (LNG) at sea from punctures on carrier hulls is presented. Models from literature combined mechanisms of flow thorough an orifice, formation of a semicircular pool, vaporization of a cryogenic fluid by boiling and pool fire heating, ignition, non-premixed turbulent fire with variation with height of the emissive power of the ‘visible’ plume, burning of fuel along the ‘luminous’ zone (fire base) and radiation emitted by gray gases and soot particles from the combustion zone. A review of the experimental data on vaporization velocity and burning rate is presented. Predictions agreed well with existing experimental data and other models. The model simulated fires from 1 to 5 m diameter holes in vessel geometries of 125,000 and 265,000 m 3 . Predictions are plausible, and robust enough to be applied in industrial practice. The construction of an LNG terminal involves, among other parameters, the prediction of thermal radiation fields emitted by pool fires. This is to evaluate safe distances to vulnerable resources around the facility. -- Highlights: • More than 20 orifice models published since 1969 were reviewed. • Flow parameter adjusted with proxy equations for a ∗,max and t * v within 1/3 ≤ ϕ ≤ 30. • Review of experimental of data for vaporization velocities covered since 1978. • The axial emissive power along the fire plume increases with vaporization velocity. • Plume height/diameter ratio of termal plume was nearly insensitive to the scale up of carrier cargo capacity

    The goal of the U.S. Department of Energy cooperative research project is to define, describe, and validate, a process to utilize salt caverns to receive and store the cargoes of LNG ships. The project defines the process as receiving LNG from a ship, pumping the LNG up to cavern injection pressures, warming it to cavern compatible temperatures, injecting the warmed vapor directly into salt caverns for storage, and distribution to the pipeline network. The performance of work under this agreement is based on U.S. Patent 5,511,905, and other U.S. and Foreign pending patent applications. The cost sharing participants in the research are The National Energy Technology Laboratory (U.S. Department of Energy), BP America Production Company, Bluewater Offshore Production Systems (U.S.A.), Inc., and HNG Storage, L.P. Initial results indicate that a salt cavern based receiving terminal could be built at about half the capital cost, less than half the operating costs and would have significantly higher delivery capacity, shorter construction time, and be much more secure than a conventional liquid tank based terminal. There is a significant body of knowledge and practice concerning natural gas storage in salt caverns, and there is a considerable body of knowledge and practice in handling LNG, but there has never been any attempt to develop a process whereby the two technologies can be combined. Salt cavern storage is infinitely more secure than surface storage tanks, far less susceptible to accidents or terrorist acts, and much more acceptable to the community. The project team developed conceptual designs of two salt cavern based LNG terminals, one with caverns located in Calcasieu Parish Louisiana, and the second in Vermilion block 179 about 50 miles offshore Louisiana. These conceptual designs were compared to conventional tank based LNG terminals and demonstrate superior security, economy and capacity. The potential for the development of LNG receiving terminals

    The new tariff proposals for the use of natural gas transportation networks were transmitted to the French Ministry of economy, finances and industry on October 27, 2004 by the commission of energy regulation. These proposals have been adopted and are the object of three legislative texts: the decree no. 2005-607 from May 27 2005 relative to the tariffing rules, the by-law from May 27, 2005 relative to the definition of balancing areas, and the advice from May 27, 2005 relative to the tariffs of use of natural gas transportation networks. In application of article 7 of the law from January 3, 2003, the implementation of the first tariffs of use of natural gas transportation networks and of liquefied natural gas (LNG) facilities is defined in the decree no. 2004-994 from September 21, 2004. On the main transportation network, the tariffing is of 'input-output' type and does not depend on the distance, while at the regional network scale, the tariffing is linked with the distance. The tariff of use of LNG facilities is the sum of 4 terms: a fixed term applied to each batch unloaded at the methane terminal, a term proportional to the unloaded LNG quantities, a term depending on the duration of use of LNG storage facilities and a term covering the gas consumptions of LNG facilities. This document gathers these different legislative texts with their appendixes. (J.S.)

    Minas Gerais is a State where there is no production of natural gas. Aiming to increase the consumption of natural gas in Minas Gerais, PETROBRAS increase the network of gas natural distribution in the State of Minas Gerais and the State concessionaire (GASMIG) installed the Project of Natural Gas Valley. The case study is associated to an enterprise that firmed contract for supplying of natural gas. The fuel to be substituted is the Liquefied Petroleum Gas and the results of the substitution were shown. The advantages of the substitution were related to costs, and environmental aspects with the reduction of CO{sub 2} production. The natural gas contains a lower content of impurities and is operated with higher safety than the petroleum liquefied gas. (author)

    In the late 1990's, PETROBRAS began considering diversifying its energy sources. This included the possibility of importing LNG (Liquefied Natural Gas), making it one additional source for gas supply in Brazil. There is a belief that the imported LNG is the cheapest, quickest and most efficient option in terms of infrastructure compared to other transportation, such as pipelines. This will permit an increase in gas supply, given the growing demand for this energy source in the domestic market. The current international LNG trading market is adjusting itself to the world integration, where short-term (spot) agreements prevail. These agreements have many advantages, such as: lowering fixed trading costs; the possibility to diversify suppliers; minimizing gas supply risk; and facilitating import market supply adjustment. In Brazil, the main objective to import LNG is to supply natural gas (NG) to thermal plants, supplementing the hydroelectric - gas integration of the electric system. For the accomplishment of this project, it is forecasted the construction of LNG offloading terminals, together with the construction of gas distribution networks. Therefore, LNG transportation will guarantee security in supply, permit the diversification of the NG supply source and enable the increased use of NG in the Brazilian energy grid. (author)

    Ports act as essential hubs in the global economy. But the rise in maritime traffic is taking a toll on the quality of air in ports and out at sea. From 2015 onwards, threshold governing harmful emissions are being tightened in a bid to clear the air. All of which is driving interest in more environmentally sound fuels. Liquefied natural gas (LNG) is the perfect fit, more than complying with the upcoming regulations. To enable its widespread adoption, Linde is working full steam ahead to create a network of LNG terminals in Europe. (orig.)

    In the case of a confinement loss (breakage of a connection piece) on a pressurized liquefied gas tank, a critical two-phase (liquid-vapour) flow is generated. This thesis is aimed at the validation of models describing these flows with various fluids (water, R 11, methanol, ethyl acetate, pure butane, commercial butane), using a pilot experimental plant. Results show that reduced upstream pressure is the main parameter, thus indicating that a model can be validated using minimal fluids. The homogenous models DEM and HRM appear to be more precise

    2008-01-01

    In a letter to the U.S. Geological Survey (USGS) dated March 25, 2008, Representative Jane Harman (California 36th district) requested advice on geologic hazards that should be considered in the review of a proposed liquefied natural gas (LNG) facility off the California coast in Santa Monica Bay. In 2004, the USGS responded to a similar request from Representative Lois Capps, regarding two proposed LNG facilities offshore Ventura County, Calif., with a report summarizing potential geologic and seismic hazards (Ross and others, 2004). The proposed LNG Deepwater Port (DWP) facility includes single point moorings (SPMs) and 35 miles of underwater pipelines. The DWP submersible buoys, manifolds, and risers would be situated on the floor of the southern Santa Monica Basin, in 3,000 feet of water, about 23 miles offshore of the Palos Verdes Peninsula. Twin 24-inch diameter pipelines would extend northeastward from the buoys across the basin floor, up the basin slope and across the continental shelf, skirting north around the Santa Monica submarine canyon. Figure 1 provides locations of the project and geologic features. Acronyms are defined in table 1. This facility is being proposed in a region of known geologic hazards that arise from both the potential for strong earthquakes and geologic processes related to sediment transport and accumulation in the offshore environment. The probability of a damaging earthquake (considered here as magnitude 6.5 or greater) in the next 30 years within about 30 miles (50 km) of the proposed pipeline ranges from 16% at the pipeline's offshore end to 48% where it nears land (Petersen, 2008). Earthquakes of this magnitude are capable of producing strong shaking, surface fault offsets, liquefaction phenomena, landslides, underwater turbidity currents and debris flow avalanches, and tsunamis.

    Full Text Available As a new kind of highly compact and efficient micro-channel heat exchanger, the printed circuit heat exchanger (PCHE is a promising candidate satisfying the heat exchange requirements of liquefied natural gas (LNG vaporization at low and high pressure. The effects of airfoil fin arrangement on heat transfer and flow resistance were numerically investigated using supercritical liquefied natural gas (LNG as working fluid. The thermal properties of supercritical LNG were tested by utilizing the REFPROF software database. Numerical simulations were performed using FLUENT. The inlet temperature of supercritical LNG was 121 K, and its pressure was 10.5 MPa. The reference mass flow rate of LNG was set as 1.22 g/s for the vertical pitch Lv = 1.67 mm and the staggered pitch Ls = 0 mm, with the Reynolds number of about 3750. The SST k-ω model was selected and verified by comparing with the experimental data using supercritical liquid nitrogen as cold fluid. The airfoil fin PCHE had better thermal-hydraulic performance than that of the straight channel PCHE. Moreover, the airfoil fins with staggered arrangement displayed better thermal performance than that of the fins with parallel arrangement. The thermal-hydraulic performance of airfoil fin PCHE was improved with increasing Ls and Lv. Moreover, Lv affected the Nusselt number and pressure drop of airfoil fin PCHE more obviously. In conclusion, a sparser staggered arrangement of fins showed a better thermal-hydraulic performance in airfoil fin PCHE.

    A novel energy and cost effective transport chain for stranded natural gas utilized for power production with CO 2 capture and storage is developed. It includes an offshore section, a combined gas carrier, and an integrated receiving terminal. In the offshore process, natural gas (NG) is liquefied to LNG by liquid carbon dioxide (LCO 2 ) and liquid inert nitrogen (LIN), which are used as cold carriers. The offshore process is self-supported with power, hot and cold utilities and can operate with little rotating equipment and without flammable refrigerants. In the onshore process, the cryogenic exergy in LNG is used to cool and liquefy the cold carriers, which reduces the power requirement to 319 kWh/tonne LNG. Pinch and exergy analyses are used to determine thermodynamically optimized offshore and onshore processes with exergy efficiencies of 87% and 71%, respectively. There are very low emissions from the processes. The estimated specific costs for the offshore and onshore process are 8.0 and 14.6 EUR per tonne LNG, respectively, excluding energy costs. With an electricity price of 100 EUR per MWh, the specific cost of energy in the onshore process is 31.9 EUR per tonne LNG

    A novel transport chain for stranded natural gas utilized for power production with CO 2 capture and storage is developed. It includes an offshore section, a combined gas carrier, and an onshore integrated receiving terminal. Due to utilization of the cold exergy both in the offshore and onshore processes, and combined use of the gas carrier, the transport chain is both energy and cost effective. In this paper, the liquefied energy chain (LEC) is explained, including novel processes for both the offshore field site and onshore market site. In the offshore section, natural gas (NG) is liquefied to LNG by liquid carbon dioxide (LCO 2 ) and liquid inert nitrogen (LIN), which are used as cold carriers. The LNG is transported in a combined gas carrier to the receiving terminal where it is used as a cooling agent to liquefy CO 2 and nitrogen. The LCO 2 and LIN are transported offshore using the same combined carrier. Pinch and Exergy Analyses are used to determine the optimal offshore and onshore processes and the best transport conditions. The exergy efficiency for a thermodynamically optimized process is 87% and 71% for the offshore and onshore processes, respectively, yielding a total efficiency of 52%. The offshore process is self-supported with power and can operate with few units of rotating equipment and without flammable refrigerants. The loss of natural gas due to power generation for the energy requirements in the LEC processes is roughly one third of the loss in a conventional transport chain for stranded natural gas with CO 2 sequestration. The LEC has several configurations and can be used for small scale ( 5 MTPA LNG) transport. In the example in this paper, the total costs for the simple LEC including transport of natural gas to a 400 MW net power plant and return of 85% of the corresponding carbon as CO 2 for a total sailing distance of 24 h are 58.1 EUR/tonne LNG excluding or including the cost of power. The total power requirements are 319 k

    Highlights: • Exergoeconomic analyses is done on an integrated cryogenic air separation unit. • Liquefied natural gas cold energy is used in the process. • The main multi stream heat exchanger is the worst device based on the results. - Abstract: Exergoeconomic and sensitivity analyses are performed on the integrated cryogenic air separation unit, oxy-combustion Carbon dioxide power cycle and liquefied natural gas regasification process. Exergy destruction, exergy efficiency, cost rate of exergy destruction, cost rate of capital investment and operating and maintenance, exergoeconomic factor and relative cost difference have been calculated for the major components of the process. The exergy efficiency of the process is around 67.1% and after mixers, tees, tank and expansion valves the multi-stream heat exchanger H-3 have the best exergy efficiency among all process components. Total exergy destruction rate of the process is 1.93 × 10"7 kW. Results of exergoeconomic analysis demonstrates that maximum exergy destruction and capital investment operating and maintenance cost rate are related to the multi-stream heat exchanger H-1 and pump P-1 with the values of 335,144 ($/h) and 12,838 ($/h), respectively. In the sensitivity analysis section the effects of the varying economic parameters, such as interest rate and plant life time are investigated on the trend of the capital investment operating and maintenance cost rate of the major components of the process and in another cases the effect of the gas turbine isentropic efficiency on the exergy and exergoeconomic parameters are studied.

    The increase in demand for natural gas in the world, cause that the production of liquefied natural gas (LNG) and in consequences its regasification becoming more common process related to its transportation. Liquefied gas is transported in the tanks at a temperature of about 111K at atmospheric pressure. The process required to convert LNG from a liquid to a gas phase for further pipeline transport, allows the use of exergy of LNG to various applications, including for electricity generation. Exergy analysis is a well known technique for analyzing irreversible losses in a separate process. It allows to specify the distribution, the source and size of the irreversible losses in energy systems, and thus provide guidelines for energy efficiency. Because both the LNG regasification and liquefaction of natural gas are energy intensive, exergy analysis process is essential for designing highly efficient cryogenic installations. Wzrost zapotrzebowania na gaz ziemny na świecie powoduje, że produkcja skroplonego gazu ziemnego (LNG), a w konsekwencji jego regazyfikacja, staje się coraz bardziej powszechnym procesem związanym z jego transportem. Skroplony gaz transportowany jest w zbiornikach w temperaturze około 111K pod ciśnieniem atmosferycznym. Przebieg procesu regazyfikacji niezbędny do zamiany LNG z fazy ciekłej w gazową dla dalszego transportu w sieci, umożliwia wykorzystanie egzergii LNG do różnych zastosowań, między innymi do produkcji energii elektrycznej. Analiza egzergii jest znaną techniką analizowania nieodwracalnych strat w wydzielonym procesie. Pozwala na określenie dystrybucji, źródła i wielkości nieodwracalnych strat w systemach energetycznych, a więc ustalić wytyczne dotyczące efektywnego zużycia energii. Ponieważ zarówno regazyfikacja LNG jak i skraplanie gazu ziemnego są energochłonne, proces analizy egzergii jest niezbędny do projektowania wysoce wydajnych instalacji kriogenicznych.

    The utilization of unconventional natural gas is still a great challenge for China due to its distribution locations and small reserves. Thus, liquefying the unconventional natural gas by using small-scale LNG plant in skid-mount packages is a good choice with great economic benefits. A novel conceptual design of parallel nitrogen expansion liquefaction process for small-scale plant in skid-mount packages has been proposed. It first designs a process configuration. Then, thermodynamic analysis of the process is conducted. Next, an optimization model with genetic algorithm method is developed to optimize the process. Finally, the flexibilities of the process are tested by two different feed gases. In conclusion, the proposed parallel nitrogen expansion liquefaction process can be used in small-scale LNG plant in skid-mount packages with high exergy efficiency and great economic benefits. - Highlights: • A novel design of parallel nitrogen expansion liquefaction process is proposed. • Genetic algorithm is applied to optimize the novel process. • The unit energy consumption of optimized process is 0.5163 kWh/Nm 3 . • The exergy efficiency of the optimized case is 0.3683. • The novel process has a good flexibility for different feed gas conditions

    Indonesia has abundant natural gas resources, however the primary fuel used for electricity generation is coal and oil. Insufficient natural gas infrastructure with-in the country acts as a barrier to increased natural gas usage. In Indonesia LNG is the most efficient and effective method for distributing natural gas given the difficult geographical conditions, the world’s largest archipelago and located in a deep sea area. The Government is planning to initiate natural gas imports by 2019 to meet the country’s energy demands. In order to allocate adequate amounts of natural gas across the geographic regions Indonesia must build more LNG regasification terminals. The Indonesia government has not yet determined if the additional regasification terminals will be floating or land-based facilities. This paper assesses the two options and identifies which facility attains greater profitability. The financial analysis of investing in the Sorong LNG regasification terminal project is conducted using NPV, IRR, and sensitivity analysis. This analysis demonstrates that FSRU facilities have greater economic viability than onshore LNG regasification facilities. The FSRU project earns greater than a 12% IRR as compared to a negative IRR earned by an onshore project. The government can make the onshore projects viable by increasing the sales fee from US10.00/MMBTU to US10.60/MMBTU.

  12. The design of an optical sensor arrangement for the detection of oil contamination in an adhesively bonded structure of a liquefied natural gas (LNG) ship

    Kim, Bu Gi; Lee, Dai Gil

    2009-01-01

    Liquefied natural gas (LNG) has been widely used as a substitute fuel for commercial purposes. It is transported mainly by LNG ships which have primary and secondary leakage barriers. The former is composed of welded thin stainless steel or invar plates, while the latter is composed of adhesively bonded glass composite or aluminum foil sheets. The role of the secondary barrier is to maintain fluid tightness when the primary barrier fails during the transport of LNG. The tightness of the secondary barrier is dependent on the wetting characteristics between the adhesive and adherend of the bonded structure during bonding operation, which depends much on the contamination on the adherend surface. Therefore, in this work, an optical measuring device of oil contamination on the aluminum surface for the secondary barrier was developed. A transparent oil was used as the contaminant and its effect on the bonding strength was investigated. From the experiments, it has been found that the developed measuring device for oil contamination can be used to detect oil contamination on a large bonding area of the secondary barrier in ship building yards

    As France remained apart from a movement of adoption of liquefied natural gas (LNG) in maritime applications, this report first discusses the different fuels used by ships (conventional fuels, LNG, fuel energy efficiency, LNG engines and tanks). Then, after having recalled international constraints related to atmospheric emissions by ships (MARPOL convention, European legal framework) and noticed the possible transfer to other transport mode in case of change of fuel, the authors discuss the possible solutions and show that LNG allows environmental objectives to be met whereas other conventional fuels present several drawbacks. They comment the results of some European studies on the use of LNG, propose an overview of LNG resources, availability and prices, and indicate current projects in the world. They study the implications of introduction of LNG for ships in France in terms of infrastructures, of regulation, and of compliance with different European policies. They discuss different aspects related to the creation of the associated market, the commitment of economic stakeholders, industrial stakes, pilot projects and the issue of investment financing

  20. Magnetic liquefier for hydrogen

    International Nuclear Information System (INIS)

    1992-01-01

    This document summarizes work done at the Astronautics Technology Center of the Astronautics Corporation of America (ACA) in Phase 1 of a four phase program leading to the development of a magnetic liquefier for hydrogen. The project involves the design, fabrication, installation, and operation of a hydrogen liquefier providing significantly reduced capital and operating costs, compared to present liquefiers. To achieve this goal, magnetic refrigeration, a recently developed, highly efficient refrigeration technology, will be used for the liquefaction process. Phase 1 project tasks included liquefier conceptual design and analysis, preliminary design of promising configurations, design selection, and detailed design of the selected design. Fabrication drawings and vendor specifications for the selected design were completed during detailed design. The design of a subscale, demonstration magnetic hydrogen liquefier represents a significant advance in liquefaction technology. The cost reductions that can be realized in hydrogen liquefaction in both the subscale and, more importantly, in the full-scale device are expected to have considerable impact on the use of liquid hydrogen in transportation, chemical, and electronic industries. The benefits to the nation from this technological advance will continue to have importance well into the 21st century

    The severe global water scarcity and record-high fossil oil price have greatly stimulated the research interests on new desalination technologies which can be driven by renewable energy or waste energy. In this study, a hybrid desalination process comprising freeze desalination and membrane distillation (FD-MD) processes was developed and explored in an attempt to utilize the waste cold energy released from re-gasification of liquefied natural gas (LNG). The concept of this technology was demonstrated using indirect-contact freeze desalination (ICFD) and direct-contact membrane distillation (DCMD) configurations. By optimizing the ICFD operation parameters, namely, the usage of nucleate seeds, operation duration and feed concentration, high quality drinkable water with a low salinity ∼0.144 g/L was produced in the ICFD process. At the same time, using the optimized hollow fiber module length and packing density in the DCMD process, ultra pure water with a low salinity of 0.062 g/L was attained at a condition of high energy efficiency (EE). Overall, by combining FD and MD processes and adopting the optimized operation parameters, the hybrid FD-MD system has been successfully demonstrated. A high total water recovery of 71.5% was achieved, and the water quality obtained met the standard for drinkable water. In addition, with results from specific energy calculation, it was proven that the hybrid process is an energy-saving process and utilization of LNG cold energy could greatly reduce the total energy consumption.

    A novel liquefied natural gas (LNG) fueled power plant is proposed, which has virtually zero CO{sub 2} and other emissions and a high efficiency. The plant operates as a subcritical CO{sub 2} Rankine-like cycle. Beside the power generation, the system provides refrigeration in the CO{sub 2} subcritical evaporation process, thus it is a cogeneration system with two valued products. By coupling with the LNG evaporation system as the cycle cold sink, the cycle condensation process can be achieved at a temperature much lower than ambient, and high-pressure liquid CO{sub 2} can be withdrawn from the cycle without consuming additional power. Two system variants are analyzed and compared, COOLCEP-S and COOLCEP-C. In the COOLCEP-S cycle configuration, the working fluid in the main turbine expands only to the CO{sub 2} condensation pressure; in the COOLCEP-C cycle configuration, the turbine working fluid expands to a much lower pressure (near-ambient) to produce more power. The effects of some key parameters, the turbine inlet temperature and the backpressure, on the systems' performance are investigated. It was found that at the turbine inlet temperature of 900 C, the energy efficiency of the COOLCEP-S system reaches 59%, which is higher than the 52% of the COOLCEP-C one. The capital investment cost of the economically optimized plant is estimated to be about 750 EUR/kWe and the payback period is about 8-9 years including the construction period, and the cost of electricity is estimated to be 0.031-0.034 EUR/kWh.

    Highlights: • A two-stage condensation Rankine cycle (TCRC) system is proposed. • Net power output and thermal efficiency increases by 45.27% and 42.91%. • The effects of the condensation temperatures are analyzed. • 14 working fluids (such as propane, butane etc.) are compared. - Abstract: For the low efficiency of the traditional power generation system with liquefied natural gas (LNG) cold energy utilization, by improving the heat transfer characteristic between the working fluid and LNG, this paper has proposed a two-stage condensation Rankine cycle (TCRC) system. Using propane as working fluid, compared with the combined cycle in the conventional LNG cold energy power generation method, the net power output, thermal efficiency and exergy efficiency of the TCRC system are respectively increased by 45.27%, 42.91% and 52.31%. Meanwhile, the effects of the first-stage and second-stage condensation temperature and LNG vaporization pressure on the performance and cost index of the TCRC system (net power output, thermal efficiency, exergy efficiency and UA) are analyzed. Finally, using the net power output as the objective function, with 14 organic fluids (such as propane, butane etc.) as working fluids, the first-stage and second-stage condensation temperature at different LNG vaporization pressures are optimized. The results show that there exists a first-stage and second-stage condensation temperature making the performance of the TCRC system optimal. When LNG vaporization pressure is supercritical pressure, R116 has the best economy among all the investigated working fluids, and while R150 and R23 are better when the vaporization pressure of LNG is subcritical.

  6. Hydrogen production by steam reforming of liquefied natural gas (LNG) over nickel catalysts supported on cationic surfactant-templated mesoporous aluminas

    Two types of mesoporous γ-aluminas (denoted as A-A and A-S) are prepared by a hydrothermal method under different basic conditions using cationic surfactant (cetyltrimethylammonium bromide, CTAB) as a templating agent. A-A and A-S are synthesized in a medium of ammonia solution and sodium hydroxide solution, respectively. Ni/γ-Al 2O 3 catalysts (Ni/A-A and Ni/A-S) are then prepared by an impregnation method, and are applied to hydrogen production by steam reforming of liquefied natural gas (LNG). The effect of a mesoporous γ-Al 2O 3 support on the catalytic performance of Ni/γ-Al 2O 3 is investigated. The identity of basic solution strongly affects the physical properties of the A-A and A-S supports. The high surface-area of the mesoporous γ-aluminas and the strong metal-support interaction of supported catalysts greatly enhance the dispersion of nickel species on the catalyst surface. The well-developed mesopores of the Ni/A-A and Ni/A-S catalysts prohibit the polymerization of carbon species on the catalyst surface during the reaction. In the steam reforming of LNG, both Ni/A-A and Ni/A-S catalysts give better catalytic performance than the nickel catalyst supported on commercial γ-Al 2O 3 (Ni/A-C). In addition, the Ni/A-A catalyst is superior to the Ni/A-S catalyst. The relatively strong metal-support interaction of Ni/A-A catalyst effectively suppresses the sintering of metallic nickel and the carbon deposition in the steam reforming of LNG. The large pores of the Ni/A-A catalyst also play an important role in enhancing internal mass transfer during the reaction.

    This report is the third of a series dealing with the coordination of ministerial actions in favor of the use of liquefied natural gas (LNG) as fuel in transports. LNG is an important potential substitute to diesel fuel in road transport and would allow significant abatement of nitrogen oxides emissions. Bio-LNG is ten times less polluting than fossil fuel LNG and thus important efforts are to be made in bio-LNG R and D. An important work has been carried out for adapting EU regulations and standards to LNG vehicles and LNG supply developments. This report presents, first, a summary of the report's recommendations and the aim of this coordination study, and, then, treats more thoroughly of the different coordination aspects: 1 - European framework of energy transition in the road freight transport (differences with maritime transport, CO 2 emissions abatement, trucks pollution and fuel quality standards, trucks technical specifications and equipment, fuel taxes in EU countries); 2 - European policy and national actions in favour of LNG development for road transport (LNG as alternate fuel, the Paris agreement, the French national energy plan); 3 - Environmental benefits of LNG in road transport (public health impacts, nitrogen oxides abatement, divergent views and expertise, LNG and CO 2 abatement measures, bio-LNG environmental evaluation; 4 - LNG development actors in road transport and the administrative coordination (professional organizations, public stakeholders, LNG topics information dissemination at the Ministry); 5 - LNG development in road transport at the worldwide, European and national scales; 6 - European regulations and standards allowing trucks LNG fueling and circulation (standard needs, users information, regulation works); 7 - Common rules to define and implement for personnel training; 8 - reflexion on LNG taxation; 9 - support policy for a road transport LNG supply chain (infrastructures, European financing, lessons learnt from maritime

    Highlights: • A small scale transcritical Carbon dioxide cycle is investigated. • Exergoeconomic analysis of a CO_2 power cycle driven by geothermal energy with LNG as its heat sink. • Three decision-making methods are employed to select final answers. - Abstract: In this study a transcritical Carbon dioxide power cycle has been coupled to a liquefied natural gas to work either as the cold source and to further enhance to generate electricity. The detailed thermodynamic analysis is performed in order to investigate the effect of key parameters on the cycle performance. Also, heat exchangers are measured to find the heat transfer surface area for economic evaluation. To investigate the aforementioned cycle and for optimization purposes, an exergoeconomic analysis is done to know the important components with respect to exergoeconomic criterion. The exergoeconomic analysis reveals that Carbon dioxide turbine and condenser have the highest rate of sum cost rate associated with capital investment and the cost of exergy destruction and special attention should be paid to these components. The parametric analysis shows that there is an optimum turbine inlet pressure which brings about the highest exergy efficiency and lowest product cost rate. Moreover, the condensate pressure has the highest effect on system exergy efficiency compared to others. With the help of multi-objective optimization, the cumulative effects of these variables are investigated on the system to maximize the exergetic efficiency and to minimize the product cost rate of the system. Results show that the system is capable of producing power with exergy efficiency and product cost rate equal to 20.5% and 263592.15 $/year, respectively, according to technique for order of preference by similarity to ideal solution decision making technique. Also, the system exergy efficiency of 22.1% and 295001.26 $/year product cost rate is achieved through linear programming techniques for multidimensional

    The conversion potential to replace oil in the energy intensive industries and diesel in heavy transport is estimated in the study to 6.8 TWh and 10 TWh per year, respectively. Several alternative fuels compete for this conversion potential. What fuels will take market share depends on several factors such as price, availability of fuel, availability of process technology and vehicles, technology development and possible future technological advances. For liquid methane to compete a new infrastructure is required that in a cost effective manner makes it possible to distribute the liquid methane to the regions where the need is the greatest. With today's distribution system, including truck delivery from import terminals in Nynaeshamn and Fredrikstad, virtually the entire southern Sweden is within reach of LNG deliveries. The study points out three nodes, Gaevle, Sundsvall and Luleaa, which is suitable for distribution of liquid methane to the central and northern Sweden. The three hubs are suitable for freight transfer to trucks as well as rail and shipping. A strategic nationwide network of refueling stations is also proposed, with a total of 18 new stations, in addition to the filling stations in southern and central Sweden that are already planned or in operation. Both the availability and use of liquid methane in Sweden today is limited. Liquid natural gas, LNG (liquefied natural gas), is primarily used as a backup to biogas plants, in a few industries and as supply for a few filling stations for compressed gas. The availability of LNG and also liquid biogas (LBG liquefied biogas), will increase in coming years. In 2011, two new LNG import terminals are put into operation in Nynaeshamn and Fredrikstad in Norway and two additional import terminals are planned in Gothenburg and Lysekil. Furthermore, two production plants for liquid biogas production have started, and four additional plants are planned, which together will produce around 0.5 TWh LBG annually

    2009-01-01

    A novel energy and cost effective transport chain for stranded natural gas utilized for power production with CO 2 capture and storage is developed. It includes an offshore section, a combined gas carrier and an integrated receiving terminal. In the offshore section, natural gas (NG) is liquefied to LNG by liquid carbon dioxide (LCO 2 ) and liquid inert nitrogen (LIN), which are used as cold carriers. In the onshore process, the cryogenic exergy in the LNG is utilized to cool and liquefy the cold carriers, LCO 2 and LIN. The transport pressures for LNG, LIN and LCO 2 will influence the thermodynamic efficiency as well as the ship utilization; hence sensitivity analyses are performed, showing that the ship utilization for the payload will vary between 58% and 80%, and the transport chain exergy efficiency between 48% and 52%. A thermodynamically optimized process requires 319 kWh/tonne LNG. The NG lost due to power generation needed to operate the LEC processes is roughly one third of the requirement in a conventional transport chain for stranded NG gas with CO 2 capture and sequestration (CCS)

    This final report for the DOE Project entitled Active Magnetic Regenerative Liquefier (AMRL) funded under Grant DE-FG36-08GO18064 to Heracles Energy Corporation d.b.a. Prometheus Energy (Heracles/Prometheus) describes an active magnetic regenerative refrigerator (AMRR) prototype designed and built during the period from July 2008 through May 2011. The primary goal of this project was to make significant technical advances toward highly efficient liquefaction of hydrogen. Conventional hydrogen liquefiers at any scale have a maximum FOM of ~0.35 due primarily to the intrinsic difficulty of rapid, efficient compression of either hydrogen or helium working gases. Numerical simulation modeling of high performance AMRL designs indicates certain designs have promise to increase thermodynamic efficiency from a FOM of ~0.35 toward ~0.5 to ~0.6. The technical approach was the use of solid magnetic working refrigerants cycled in and out of high magnetic fields to build an efficient active regenerative magnetic refrigeration module providing cooling power for AMRL. A single-stage reciprocating AMRR with a design temperature span from ~290 K to ~120 K was built and tested with dual magnetic regenerators moving in and out of the conductively-cooled superconducting magnet subsystem. The heat transfer fluid (helium) was coupled to the process stream (refrigeration/liquefaction load) via high performance heat exchangers. In order to maximize AMRR efficiency a helium bypass loop with adjustable flow was incorporated in the design because the thermal mass of magnetic refrigerants is higher in low magnetic field than in high magnetic field. Heracles/Prometheus designed experiments to measure AMRR performance under a variety of different operational parameters such as cycle frequency, magnetic field strength, heat transfer fluid flow rate, amount of bypass flow of the heat transfer fluid while measuring work input, temperature span, cooling capability as a function of cold temperature

    The purpose of law is to prevent the society from harm by declaring what conduct is criminal, and prescribing the punishment to be imposed for such conduct. The pervasiveness of the internet and its anonymous nature make cyberspace a lawless frontier where anarchy prevails. Historically, economic value has been assigned to visible and tangible assets. With the increasing appreciation that intangible data disseminated through an intangible medium can possess economic value, cybercrime is also being recognized as an economic asset. The Cybercrime, Digital Forensics  and Jurisdiction disseminate knowledge for everyone involved with understanding and preventing cybercrime - business entities, private citizens, and government agencies. The book is firmly rooted in the law demonstrating that a viable strategy to confront cybercrime must be international in scope.

    The Brazilian Government, through the Program of massification of the use of the natural gas (NG), it tries to motivate the increase of the participation of this fuel in the national energy head office, stimulating his/her use in the most several sections. In the specific case of the Northeast, where thankfully problems of offer of this energy one exist, the discussion fits if the current proposal of the construction of costly gas pipelines should be implemented or she should use alternative forms to supply the demand for NG of the area (virtual gas pipelines: LNG or CNG). These technologies can induce the use in mass of NG, allowing not only the use of this energy nobleman for great consumers, as well as for the small ones, stimulating the increase of the energy efficiency. This article has as objective to do a reflection on the Northeastern market of NG and the forms of provisioning, using LNG, of areas now no assisted by the mesh of gas pipelines and that you/they are potential consuming. Before that solution alternatives will be discussed for a crucial subject in the expansion of the market of NG: the need of the construction of gas pipelines to supply markets no formed. Corroborating, like this, with the Plan of massification of the use of NG, generating alternative subsidies for the projects of expansion of markets of the energy. (author)

    A nickel-phosphorus-alumina xerogel catalyst was prepared by a carbon-templating epoxide-driven sol-gel method (denoted as CNPA catalyst), and it was applied to the hydrogen production by steam reforming of liquefied natural gas (LNG). For comparison, a nickel-phosphorus-alumina xerogel catalyst was also prepared by a similar method in the absence of carbon template (denoted as NPA catalyst). The effect of carbon template addition on the physicochemical properties and catalytic activities of the catalysts in the steam reforming of LNG was investigated. Both CNPA and NPA catalysts showed excellent textural properties with well-developed mesoporous structure. However, CNPA catalyst retained a more reducible nickel aluminate phase than NPA catalyst. XRD analysis of the reduced CNPA and NPA catalysts revealed that nickel sintering on the CNPA catalyst was suppressed compared to that on the NPA catalyst. From H2-TPD and CH4-TPD measurements of the reduced CNPA and NPA catalysts, it was also revealed that CNPA catalyst with large amount of hydrogen uptake and strong hydrogen-binding sites showed larger amount of methane adsorption than NPA catalyst. In the hydrogen production by steam reforming of LNG, CNPA catalyst with large methane adsorption capacity showed a better catalytic activity than NPA catalyst.

    This work evaluates the possibilities of taking advantage of the heat transferred in the re-gasification process of liquid natural gas (LNG). It is proposed the coupling of a Brayton-Rankine combined heat and power plant (CHP) to a LNG re-gasification plant in order to use the heat involved in this process as cold source for the CHP plant. For comparison, the same CHP is simulated exchanging heat with a reference environment. An analysis is performed assuming that the amount of natural gas fed to the Brayton sub-cycle combustion chamber is equal for both cases. The CHP coupled to the re-gasification plant present a net power generation of 22.7 MW and the efficiency is 45.5%. It represents a gain of 2.98 MW in the power generation and 15% in the cycle efficiency, when compared to the reference cycle. The exergetic efficiency with this proposal is 49.3%, which is 9% higher than the reference cycle. (author)

    For a long time, the right of nature conservation and landscape conservation showed a shadowy existence in the approval of projects. Some actual decisions of the Supreme Court show that in the last years the nature conservation law developed to a central area of conflict in the licensing procedure. The contribution under consideration reports on the legal material using three selected problem areas from the law on the protection of area and law on the protection of species. On the one hand, the Federal Administrative Court (Leipzig, Federal Republic of Germany) always upgrades the requirements. However, on the other hand the Federal Administrative Court attaches great importance to practicability. The Federal Administrative Court often points to a way, how projects can be realized with a careful nature conservation related attendance also at difficult environmental conditions.

    This paper discussed the proposed construction of a liquefied natural gas (LNG) terminal 15 km northeast of Riviere-du-Loup, Quebec, in area that has strong land and marine biodiversity. The proposed project to import LNG for the North American market would involve the construction of ship docking facilities, transhipment facilities, and ground storage facilities. Quebec's environmental agency, the Bureau d'audiences publiques sur l'environnement (BAPE) examined the sustainability of the project with respect to biophysical aspects, social, economic and cultural development, as well as the environment, health, and public safety. Public hearings for the project attracted many citizens, First Nation groups and corporations with two opinions, for and against the project. Those in favour mentioned that Quebec must diversify its usual source of LNG from the west and that the project would promote competition. People at the public hearing expressed concerns for the quality of life, public health, air quality, noise pollution, visual impairment of the landscape, the security related to the operations of the terminal and navigation, public safety, recreational activities, marine mammals, fish, birds, animals, marshlands, greenhouse gas emissions, water pollution and soil pollution. This paper also outlined the state of the North-American market for LNG and its evolution; LNG supply and demand for the next twenty years; changes in gas prices; and emergency planning for the implementation of the project. BAPE recommended that the environmental monitoring and tracking be done by a project proponent. It was concluded that the proposed project would create competition with western Canada due to continually higher LNG prices, and would promote local jobs during the construction phase. 41 refs., 7 tabs., 8 figs.

  9. Effect of SiO 2-ZrO 2 supports prepared by a grafting method on hydrogen production by steam reforming of liquefied natural gas over Ni/SiO 2-ZrO 2 catalysts

    Science.gov (United States)

    Seo, Jeong Gil; Youn, Min Hye; Song, In Kyu

    SiO 2-ZrO 2 supports with various zirconium contents are prepared by grafting a zirconium precursor onto the surface of commercial Carbosil silica. Ni(20 wt.%)/SiO 2-ZrO 2 catalysts are then prepared by an impregnation method, and are applied to hydrogen production by steam reforming of liquefied natural gas (LNG). The effect of SiO 2-ZrO 2 supports on the performance of the Ni(20 wt.%)/SiO 2-ZrO 2 catalysts is investigated. SiO 2-ZrO 2 prepared by a grafting method serves as an efficient support for the nickel catalyst in the steam reforming of LNG. Zirconia enhances the resistance of silica to steam significantly and increases the interaction between nickel and the support, and furthermore, prevents the growth of nickel oxide species during the calcination process through the formation of a ZrO 2-SiO 2 composite structure. The crystalline structures and catalytic activities of the Ni(20 wt.%)/SiO 2-ZrO 2 catalysts are strongly influenced by the amount of zirconium grafted. The conversion of LNG and the yield of hydrogen show volcano-shaped curves with respect to zirconium content. Among the catalysts tested, the Ni(20 wt.%)/SiO 2-ZrO 2 (Zr/Si = 0.54) sample shows the best catalytic performance in terms of both LNG conversion and hydrogen yield. The well-developed and pure tetragonal phase of ZrO 2-SiO 2 (Zr/Si = 0.54) appears to play an important role in the adsorption of steam and subsequent spillover of steam from the support to the active nickel. The small particle size of the metallic nickel in the Ni(20 wt.%)/SiO 2-ZrO 2 (Zr/Si = 0.54) catalyst is also responsible for its high performance.

  10. Automatically varying the composition of a mixed refrigerant solution for single mixed refrigerant LNG (liquefied natural gas) process at changing working conditions

    The SMR (single mixed refrigerant) process is widely used in the small- and medium-scale liquefaction of NG (natural gas). Operating the MR (mixed-refrigerant) process outside of the design specifications is difficult but essential to save energy. Nevertheless, it is difficult to realize because the process needs to alter the working refrigerant composition. To address this challenge, this study investigated the performance diagnosis mechanism for SMR process. A control strategy was then proposed to control the changes in working refrigerant composition under different working conditions. This strategy separates the working refrigerant flow in the SMR process into three flows through two phase separators before it flows into the cold box. The first liquid flow is rich in the high-temperature component (isopentane). The second liquid flow is rich in the middle-temperature components (ethylene and propane), and the gas flow is rich in the low-temperature components (nitrogen and methane). By adjusting the flow rates, it is easy to decouple the control variables and automate the system. Finally, this approach was validated by process simulation and shown to be highly adaptive and exergy efficient in response to changing working conditions. - Highlights: • The performance diagnosis mechanism of SMR LNG process is studied. • A measure to automatically change the operation composition as per the working conditions is proposed for SMR process. • SMR process simulation is performed to verify the validity of the control solution. • The control solution notably improves the energy efficiency of SMR process at changing working condition

    Germany needs an LNG receiving terminal to import LNG and supplement expected future gas supply shortages. Enormous economic benefits also abound if Germany is to install an LNG receiving terminal. Jobs will be created for several hundred people. New tax revenues will be generated for state and local governments and this will further enhance the economic competitiveness of Germany. Additionally, it will provide Germany with a reliable source of clean-burning energy. Any proposed LNG receiving terminal should incorporate safety right from the start. These safety requirements will: ensure that certain public land uses, people, and structures outside the LNG facility boundaries are protected in the event of LNG fire, prevent vapour clouds associated with an LNG spill from reaching a property line that can be built upon, prevent severe burns resulting from thermal radiation, specify requirements for design, construction and use of LNG facilities and other equipments, and promote safe, secure and reliable LNG operations. The German future LNG business will not be complete without the evolution of both local and international standards that can apply to LNG operations. Currently existing European standards also appear inadequate. With an OHSAS 18001 management system integrated with other existing standards we can better control our LNG occupational health and safety risks, and improve performance in the process. Additionally, an OHSAS 18001 System will help future German LNG contractors and operators safeguard their most important assets - their employees. (orig.)

    The US Department of Energy's liquefied Gaseous Fuels Spill Test Facility is a research and demonstration facility available on a user-fee basis to private and public sector test and training sponsors concerned with safety aspects of hazardous chemicals. Though initially designed to accommodate large liquefied natural gas releases, the Spill Test Facility (STF) can also accommodate hazardous materials training and safety-related testing of most chemicals in commercial use. The STF is located at DOE's Nevada Test Site near Mercury, Nevada, USA. Utilization of the Spill Test Facility provides a unique opportunity for industry and other users to conduct hazardous materials testing and training. The Spill Test Facility is the only facility of its kind for either large- or small-scale testing of hazardous and toxic fluids including wind tunnel testing under controlled conditions. It is ideally suited for test sponsors to develop verified data on prevention, mitigation, clean-up, and environmental effects of toxic and hazardous gaseous liquids. The facility site also supports structured training for hazardous spills, mitigation, and clean-up. Since 1986, the Spill Test Facility has been utilized for releases to evaluate the patterns of dispersion, mitigation techniques, and combustion characteristics of select materials. Use of the facility can also aid users in developing emergency planning under US P.L 99-499, the Superfund Amendments and Reauthorization Act of 1986 (SARA) and other regulations. The Spill Test Facility Program is managed by the US Department of Energy (DOE), Office of Fossil Energy (FE) with the support and assistance of other divisions of US DOE and the US Government. DOE/FE serves as facilitator and business manager for the Spill Test Facility and site.

    The present study, as part of the studies on coal liquefying technologies, was originally intended to develop optimal catalysts that make it possible to manufacture a liquid fuel from hydrogenation treatment of coal, and establish optimal reaction operation for the liquefaction process. To achieve the intentions, studies were moved forward on the following four sub-themes: (1) fundamentals and developmental research on catalysts for the direct liquefaction, (2) chemical structures of organic constituents in the coal liquefaction process, (3) research on the optimal reaction operation in the direct coal liquefaction process, and (4) studies on nature and behavior of ash constituent in the coal liquefaction process. The current fiscal year has performed the discussions on the following items based on the achievements attained by fiscal 1987: 1. as a study on liquefaction catalysts, (1) a study on properties of liquefaction catalysts, and (2) a study on characteristics of the liquefying reaction; 2. as a study on the analytic method, (1) a study on the liquefying reaction analyzing method, and (2) a study on the liquefied oil property analyzing method. In Item 1-(1), a prototype zeolite-based catalyst having high hydrogenating decomposition activity was used to execute a reaction to lighten the liquefied oil. As a result, it was revealed that the liquefied oil can be lightened efficiently by having the oil go through a two-stage reforming reaction. (NEDO)

    Full Text Available This paper will consider the practical settlement of conflicts of jurisdiction both in relation to the forum for prosecution and transfer of proceedings. The corollary of free movement of people is free movement of judgments, sentences and related powers of investigation and prosecution. Cross border crime requires to be addressed by equipping law enforcement and prosecution authorities with mechanisms to ensure the public interest in the investigation and prosecution of crime is met. The starting point for any consideration is the place where the criminal conduct took place. Sometimes the crime is such that criminal jurisdiction will be fixed - such as theft of property, crimes of violence - where others have an impact or criminal conduct in more than one jurisdiction - drug importation, major transnational drug dealing, human trafficking, terrorism.

    This paper describes the achievements in the Sunshine Project in fiscal 1988 in studies on coal liquefying catalysts and a method for analyzing liquefied oil. Acidic nature of the carrier was controlled, and deposition of carbonaceous substance on the catalyst was successfully suppressed while maintaining hydrogenation activity of the catalyst. It was possible to control hydrogenation activity of the liquefying catalyst by controlling the sulfurizing condition and the coalescence condition of Mo. Microscopic structural change in catalytically active metals due to oxygen compounds in the hydrogenation process of the liquefied oil was made clear, and so was the hydrogenation activity declining behavior associated therewith. A method was discovered that can evaluate easily and sensitively the individual functions of hydrogenation activity and hydrogenating decomposition activity of the catalyst. In the study on liquefying reaction characteristics, a fundamental study was performed to analyze the catalyst reaction characteristics in the secondary hydrogenation of liquefied oil. Studies on an analyzing method for the liquefied oil characteristics included those on NRM spectrum database, dynamic behavior of aromatic hydrocarbons in the liquefying solvent during the hydrogenating reaction, analysis of contact hydrogenating reaction using SEC, and stability of the solvent composition in the NEDOL liquefaction process.

    Hedegard, K.; Atkins, E.; Walker, G.

    1990-01-01

    A closed-cycle Linde-Hampson nitrogen liquefier was developed incorporating a new, non-clogging, demand flow Joule-Thomson nozzle. The flow area of the nozzle, a tapered annular orifice, is regulated by a very rugged load-sensitive differential thermal expansion scheme and by a manually adjustable micrometer mechanism. Labyrinth flow spoilers within the orifice provide turbulent voids which break up and clear contaminants from the flow. The system's four-stage compressor features sealed, oil-free compression spaces and a very compact nested piston configuration with a minimum of moving parts and drive complexity. The drive mechanism is a rolling Scotch yoke which minimizes piston side forces and seal wear for prolonged operating life. The closed-cycled system is controlled by an innovative load-responsive electronic feedback circuit which further reduces wear and input power. 6 refs

    Full Text Available The existence of two degrees of jurisdiction, the use of a single way of attack, the recourse, and the suppressing of the attack path of the appeal in the matter of labour conflicts, does not constitute unconstitutional dispositions. They have as finality only the assurance of the rapidity in solving such conflicts, without breaching the constitutional disposition according to which no law can restrict access to justice. I've tried to find the new regulation in this domain very important for those who practice labour law. In the Romanian legislation, the enforcement of the court decisions in the matter of labour conflicts is viewed by the lawmaker with great care, in certain cases the non-execution of a court decision being considered a felony. We think this article is a small step in the disclosure of the problem raised by the labour jurisdiction.

    Gray wolves (Canis lupus) are managed for competing uses in the Greater Yellowstone Ecosystem (GYE). Tourism benefits Yellowstone National Park (YNP) visitors while trophy hunting benefits hunters outside of the park. We investigate the policy scope of gray wolf management across jurisdictional boundaries by incorporating three foundations of the behavioral ecology of wolves: refuge-seeking behavior, optimal foraging group size and territoriality. Tradeoffs between and within consumptive and non-consumptive human benefits and wolf population fitness and life history indicators are quantified as a set of elasticities, providing clear implications to resource managers. Our approach highlights that hunting intensity affects the provision of consumptive and non-consumptive human benefits across jurisdictional boundaries and ought to be managed accordingly. We also show that population levels are an incomplete indicator of species fitness, which may depend on how hunting policies impact underlying group ecology. Our findings suggest traditional optimization approaches to wildlife management may lead to suboptimal policy recommendations when the boundaries on the natural system are oversimplified. Highlighting the human element of wildlife management, we show that understanding tourist and hunter responses to wildlife population abundances is critical to balancing provision of consumptive and non-consumptive human uses.

    Full Text Available The global financial crisis has caused the need for a stronger positioning of the European Court of Justice in the new model of economic governance in the European Union. The Jurisdiction of the European Court of Justice contributes in creating the optimal legal control mechanism of budget spending in the European monetary law and ensure maintenance of euro-zone fiscal framework. The role of the European Court of Justice in the EMU in earlier periods was secondary, but in times of crisis, it points to the growing need of Jurisdiction's extending in the field of monetary relations between member states and respect of convergence rules. Court's Jurisdiction in resolving of monetary and fiscal disputes is increasingly implemented in determining the legal nature of international agreements, whose ratio is economic stability, where the Judgments regarding complementarities of these legal documents with primary law provisions have the crucial impact on the future direction of national fiscal policies coordination. Although, the Court's Jurisdiction in this area is still underdeveloped and Judgments are often conditioned by pragmatism reasons, by development of credible macroeconomic dialogue between Court of Justice, European Central Bank and European Court of Auditors may establish conditions for fullfiling legal gaps in the performance of monetary and fiscal Jurisdiction of the Court.

    The explosion of a road tanker transporting LNG (one person killed, two injured) is studied. The analysis shows that the explosion, which followed a two-step mode as for the failure of the vessel, could have been a boiling liquid expanding vapor explosion (BLEVE). The overpressure and thermal radiation have been estimated and related to the effects observed. Only a relatively small part of the energy released in the explosion was manifested in the pressure wave. The large fragments (the three pieces into which the tank was broken) and the truck motor were ejected at various distances along the tank's main axis. (author)

  3. The Expansion of Swiss Criminal Jurisdiction in Light of International Law

    Directory of Open Access Journals (Sweden)

    Anna Petrig

    2013-09-01

    Full Text Available Over the last few decades, a global trend of extending the reach of domestic penal power can be observed, namely driven by the changing face of crime as it becomes increasingly transnational in nature. It is demonstrated in this article that the Swiss legislature has clearly followed this global trend of broadening the extraterritorial reach of domestic criminal law, most notably since the 1980s. It has acted with particular resolve in the last decade, adding jurisdictional bases to the Swiss Criminal Code by virtue of which Swiss criminal law can be applied to many instances of conduct taking place abroad. Certain offences – specified crimes against minors and female genital mutilation – have even been subjected to an absolute and unrestricted universality principle. The Swiss legislature is not indifferent to the problems that such an expansive approach to jurisdiction may create, notably in terms of conflicts of jurisdiction. Yet, the rules it adopted to temper the effects of applying Swiss criminal law to extraterritorial conduct only partially remedy the situation. This development in Swiss law begs the question whether such an expansive approach towards jurisdiction is permissible – or even encouraged or requested by international law. Hence, this article explores to what extent international law informs the reach of domestic penal power and concludes that international law is Janus-faced with regard to the question of the geographical scope of domestic criminal law. While some of its rules push for long-arm jurisdiction, others put limits on the domestic legislature’s endeavour to expand the reach of its domestic criminal law. In light of this, the idea of adopting, on an international level, general principles governing the definition of the scope of domestic prescriptive and adjudicative jurisdiction for transnational cases is tempting, albeit difficult to realize.

    This report was given by the President of the Federal Administrative Court at a meeting of the Rechts- und Staatswissenschaftliche Vereinigung (Jurisprudence and Political Science Association) held at Duesseldorf in April 1979. It points out problems arising with the administration of justice in the field of administrative law as well as the limits set to it. If parliaments avoid to take political responsibility, the solving of political conflicts will be shifted to the other two powers. In case of controversy, jurisdiction in the field of administrative law would then have to make the final decision. It is for the legislator to preserve the function of judicial power, i.e., to exact from judges to make political, especially socio-political decisions. (HSCH) [de

    This chapter describes the testing of an automatic cooldown system. The liquefying machine examined is a CTi Model 1400. The automatic helium gas liquefying system is operated by using sequence control with a programmable controller. The automatic mode is carried out by operation of two compressors. The monitoring system consists of 41 remote sensors. Liquid level is measured by a superconducting level meter. The J-T valve and return valve, which require precise control, are operated by pulse motors. The advantages of the automatic cooldown system are reduced operator man power; temperatures and pressures are changed smoothly, so that the flow chart of automation is simple; and the system makes continuous liquefier operation possible

The construction of a liquefied natural gas (LNG) terminal at the Black Sea shore will be a new fuel gas resource allowing an additional availability of supplying resources. Assuming the existence of a LNG terminal at the sea side, different scenarios can be developed according to its capacity for covering the fuel gas demand in Romania and in the countries of Central Europe, besides the alternative underground depositing. There are medium and long term political, technical, and economic uncertainties which surpass the designer's current abilities to find solutions

The most promising routes for implementing their advantages are determined. It is found that the correct choice of flow diagram and complex parameter optimization can raise the relative available energy (mass profile characteristics) of open-throttle liquefiers with mixtures to at least four times that of nitrogen installation. The most economical scheme is one that involves mixing the components in feedback, followed by double throttling of nitrogen

Liquefying reactions were carried out under the presence of various heavy solvents having different hydrogen donating performances, or iron-based and oil soluble solvents. Liquefaction rates, yields and natures of different products were analyzed to discuss the degree of hydrogen donating performance of the solvents, the using conditions for the catalysts in the primary liquefying reaction, and the reaction conditions to enhance the product oil yield. In Item 2, hydrogenation treatment was given on the heavy oil fraction of the product oil obtained from the liquefying reaction using a heavy circulating solvent. The result was compared with the result on the medium oil fraction. Light oil fraction obtained from brown coal liquefaction was reformed to manufacture the reformed oil for engine tests. In Item 3, nature analysis and combustion tests were performed on the light oil fraction of the liquefied oil using brown coal as the material, and on the hydrogenated oil as a diesel engine fuel. The reforming effects were discussed from the amount and nature of the exhaust gas. (NEDO)

    This study endeavours to determine whether farmers adjust their consumption of natural gas and liquefied petroleum gas in response to changes in the unit price of energy. A demand model is specified and estimated. The conclusions suggest that the unit price of natural gas (liquefied petroleum gas) is a factor impacting the quantity of natural gas (liquefied petroleum gas) demanded by farmers, but there is no indication that other types of energy are substitutes for natural gas or liquefied petroleum gas. Additionally, the number of acres irrigated is an important factor driving the demand for natural gas and liquefied petroleum gas. Finally, the estimated models of natural gas and liquefied petroleum gas demand were structurally stable over the period 1971-1989. (author)

  13. Dealing with duplicate regulations and conflicting jurisdictions

    1991-01-01

    There are a number of situations where mixed wastes are regulated by dual regulations and regulators. This presentation attempts to show where such duplication exists and how it evolved historically through legislative actions. The presentation includes a discussion of strategies that have been used to deal with the problems that result from duplicate regulations and jurisdictional conflicts. The RCRA and AEA regulations are really more similar than dissimilar. There are significant issues that must be worked through with the regulators. It is most important to work with your regulators early in process. The following are suggestions for dealing with the regulators. (1) Know the regulations in advance of discussions. (2) Begin dialogue with the regulator(s) as early as possible and get to know the people you will be dealing with -- and let them know you. (3) Explain the technical/regulatory issues/problems that you face at your facility in sufficient detail that they are clearly understood, and work with the regulator(s) to reasonably address them in the language/requirements of the permit. (4) Always attempt to comply with the regulations first before going in with a variance request -- document your efforts, and be honest with your assessment of issues. (5) Don't be adversarial -- remember that the regulator has the same objectives as you do. 1 tab

    Full Text Available Liquefaction has been a main cause of damage to civil engineering structures in seismically active areas. The effects of damage of liquefaction on deep foundations are very destructive. Seismic behavior of pile foundations is widely discussed by many researchers for safer and more economic design purposes. This paper presents a pseudo-static method for analysis of piles in liquefiable soil under seismic loads. A free-field site response analysis using three-dimensional (3D numerical modeling was performed to determine kinematic loads from lateral ground displacements and inertial loads from vibration of the superstructure. The effects of various parameters, such as soil layering, kinematic and inertial forces, boundary condition of pile head and ground slope, on pile response were studied. By comparing the numerical results with the centrifuge test results, it can be concluded that the use of the p-y curves with various degradation factors in liquefiable sand gives reasonable results.

    Development of technology and understanding for large capacity helium refrigeration and liquefaction at helium temperature is indispensable for coming-up projects. A new version of helium liquefier designed and built to provide approximately 35 liters of liquid helium per hour. The refrigeration capacity of this reciprocating type expansion engine machine has been increased from its predecessor version with continuous improvement and deficiency debugging. The helium liquefier has been built using components by local industries including cryogenic Aluminum plate fin heat exchangers. Two compressors with nearly identical capacity have been deployed for the operation of system. Together they consume about 110 kW of electric power. The system employs liquid Nitrogen precooling to enhance liquid Helium yield. This paper describes details of the cryogenic expander design improvements, reconfiguration of heat exchangers, performance simulation and their experimental validation.

  9. Responding to Public Health Emergencies on Tribal Lands: Jurisdictional Challenges and Practical Solutions.

    Science.gov (United States)

    Barnard, Justin B

    2015-01-01

    Response to public health emergencies on tribal lands poses a unique challenge for state and tribal public health officials. The complexity and intensely situation-specific nature of federal Indian jurisprudence leaves considerable question as to which government entity, state or tribal, has jurisdiction on tribal lands to undertake basic emergency measures such as closure of public spaces, quarantine, compulsory medical examination, and investigation. That jurisdictional uncertainty, coupled with cultural differences and an often troubled history of tribal-state relations, threatens to significantly impede response to infectious disease outbreaks or other public health emergencies on tribal lands. Given that tribal communities may be disproportionately impacted by public health emergencies, it is critical that tribal, state, and local governments engage with each other in coordinated planning for public health threats. This Article is offered as a catalyst for such planning efforts. The Article identifies some of the most pressing jurisdictional issues that may confront governments responding to a public health emergency on tribal lands, with the aim of highlighting the nature of the problem and the need for action. The Article goes on to examine the most promising means of addressing jurisdictional uncertainty: intergovernmental agreements. Already utilized in many areas of shared interest between tribe and state, intergovernmental agreements offer neighboring state, local, and tribal governments a vehicle for delineating roles and authorities in an emergency, and may lay the groundwork for sharing resources. The Article surveys various representative tribal public health intergovernmental agreements, and concludes with suggestions for tribes and state or local governments looking to craft their own agreements.

  10. A review of low income energy assistance measures adopted in other jurisdictions

    International Nuclear Information System (INIS)

    2008-01-01

    Low-income energy assistance programs (LIEPs) have been established and implemented in many jurisdictions to help make electricity and natural gas more affordable. Low-income programs also serve many other public interest goals, such as safeguarding and protecting the public health and welfare of the citizens; augmenting incomes or standards of living for the lowest income energy customers; encouraging conservation and more efficient use of energy resources; reducing customer care costs for utilities; reducing uncollectible accounts and bad debt expense for utilities; and reducing carbon emissions and greenhouse gas levels. This report contained a summary of the policies, programs, and measures that have been implemented, mandated, or allowed by regulators in other jurisdictions to assist low-income energy consumers with electricity and natural gas costs. The report categorized the differing low income policies and programs that have been implemented and examined the effectiveness of those policies and programs as measured by the costs and benefits, as well the level of customer participation. These categories included rate discounts or waivers; modified rate designs; alternative billing methods; customer rebates; conservation and demand side management programs; budget or equal billing; payment plans for past due accounts; waivers of late payment charges; waivers or reductions of customer security deposits; limits on disconnections; and reduced or waived fees for reconnections. The report covered regulatory jurisdictions, including those in Canada, the United States, the United Kingdom, Australia, New Zealand, France, Spain, and Finland. The report also discussed the role of regulators, utilities, charitable organizations, and other interested parties in developing and implementing low-income energy assistance programs that were cost-effective and efficient. It was concluded that, in addition to rate discounts or waivers of the fixed monthly service charge, many

    Two helium liquefier/refrigerators are operational at VECC while one is dedicated for the Superconducting Cyclotron. The first helium liquefier of 50 LPH capacity from Air Liquide has already completed fifteen years of operation without any major trouble. This liquefier is being controlled by Eurotherm PC3000 make PLC. This PLC has become obsolete since last seven years or so. Though we can still manage to run the PLC system with existing spares, risk of discontinuation of the operation is always there due to unavailability of spare. In order to eliminate the risk, an equivalent PLC control system based on Siemens S7-300 was thought of. For smooth migration, total programming was done keeping the same field input and output interface, nomenclature and graphset. New program is a mix of S7-300 Graph, STL and LAD languages. One to one program verification of the entire process graph was done manually. The total program was run in simulation mode. Matlab mathematical model was also used for plant control simulations. EPICS based SCADA was used for process monitoring. As of now the entire hardware and software is ready for direct replacement with minimum required set up time.

In the absence of a minimum age law, California lags behind other states and international practice and standards. The paper aims to discuss these issues. Design/methodology/approach In this policy brief, academics across the University of California campuses examine current evidence, theory, and policy related to the minimum age of juvenile justice jurisdiction. Findings Existing evidence suggests that children lack the cognitive maturity to comprehend or benefit from formal juvenile justice processing, and diverting children from the system altogether is likely to be more beneficial for the child and for public safety. Research limitations/implications Based on current evidence and theory, the authors argue that minimum age legislation that protects children from contact with the juvenile justice system and treats them as children in need of services and support, rather than as delinquents or criminals, is an important policy goal for California and for other national and international jurisdictions lacking a minimum age law. Originality/value California has no law specifying a minimum age for juvenile justice jurisdiction, meaning that young children of any age can be processed in the juvenile justice system. This policy brief provides a rationale for a minimum age law in California and other states and jurisdictions without one.

  20. The significance of LPG in Turkish vehicular transportation: liquefied petroleum gases (LPG) in fueled systems

    Energy Technology Data Exchange (ETDEWEB)

    Balat, Mustafa [Besikduzu, Trabzon (Turkey)

    2005-04-15

    Liquefied petroleum gases (LPG) are in widespread use in homes, industry and agriculture. Among the many uses of these gases are heating and refrigeration, as a supplement for natural gas, as fuel for industrial equipment and mobile homes, in the manufacture of ethylene, and as a solvent. Worldwide LPG production is limited to about 10% of total gasoline and diesel fuel consumption and is used to a great extent for domestic and industrial purposes. Since LPG burns cleaner with less carbon build-up and oil contamination, engine wear is reduced and the life of some components, such as rings and bearings, is much longer than with gasoline. The high octane of LPG also minimizes wear from engine knock. The rapid development of LPG technology, including ease of vehicular conversion and estimations of increased LPG availability, suggest LPG will soon be recognized as a premium automotive fuel.

    Alternative energy sources can represent viable economical solutions for the energy supply problems and also minimize damages to the environment. This research paper presents an economical and technical study of three different types of cookers: a solar cooker, a hybrid cooker and a conventional LPG cooker, through simulation for one typical year in Fortaleza. The solar cooker used in the experiments is composed of two pots, an oven, a tank of storage and 2m{sup 2} of solar collector area. The hybrid cooker has the same structure of the solar one with an additional natural gas burner, and the LPG stove can be easily found in the market. To find the value of the necessary energy to make food in a solar cooker, the amount of solar radiation was measured, as well as the sensible and latent efficiencies of the used stove. In the hybrid, it was considered that the natural gas is used only in the periods of the day when the amount of solar energy is not enough to heat the system up to the desired temperature. The results show an economical and technical comparison of the three different types of cookers. (author)

  4. Exposure of a liquefied gas container to an external fire

    International Nuclear Information System (INIS)

    Raj, Phani K.

    2005-01-01

    In liquefied gas, bulk-storage facilities and plants, the separation distances between storage tanks and between a tank and a line of adjoining property that can be built are governed by local regulations and/or codes (e.g. National Fire Protection Association (NFPA) 58, 2004). Separation distance requirements have been in the NFPA 58 Code for over 60 years; however, no scientific foundations (either theoretical or experimental) are available for the specified distances. Even though the liquefied petroleum gas (LPG) industry has operated safely over the years, there is a question as to whether the code-specified distances provide sufficient safety to LPG-storage tanks, when they are exposed to large external fires. A radiation heat-transfer-based model is presented in this paper. The temporal variation of the vapor-wetted tank-wall temperature is calculated when exposed to thermal radiation from an external, non-impinging, large, 30.5 m (100 ft) diameter, highly radiative, hydrocarbon fuel (pool) fire located at a specified distance. Structural steel wall of a pressurized, liquefied gas container (such as the ASME LP-Gas tank) begins to lose its strength, when the wall temperature approaches a critical temperature, 810 K (1000 deg F). LP-Gas tank walls reaching close to this temperature will be a cause for major concern because of increased potential for tank failure, which could result in catastrophic consequences. Results from the model for exposure of different size ASME (LP-Gas) containers to a hydrocarbon pool fire of 30.5 m (100 ft) in diameter, located with its base edge at the separation distances specified by NFPA 58 [NFPA 58, Liquefied Petroleum Gas Code, Table 6.3.1, 2004 ed., National Fire Protection Association, Quincy, MA, 2004] indicate that the vapor-wetted wall temperature of the containers never reach the critical temperature under common wind conditions (0, 5 and 10 m/s), with the flame tilting towards the tank. This indicates that the separation

    MHD power generators have been investigated in the Electro-Technical Laboratory as one of the National Research and Development Programmes. A helium refrigerator-liquefier system has been developed to cool the superconducting magnet for a 1000 kW class MHD power generator. The turboexpander with low temperature gas bearings and an alternator had been developed for the MHD project at the Electro-Technical Laboratory previously. The liquefaction capacity is 250 iota/h and the refrigeration power is 2.9 kW at 20 K. The superconducting magnet is 50 tons and the cryostat has a liquid helium volume of 2700 iota. The evaporation rate is 60 to 80 iota/h. It takes, in all 2 to 3 weeks to fill the cryostat with liquid helium. (author)

    The Spallation Neutron Source (SNS) Central Helium Liquefier (CHL) at Oak Ridge National Laboratory (ORNL) has been without major operations downtime since operations were started back in 2006. This system utilizes a vessel filled with activated carbon as the final major component to remove oil vapor from the compressed helium circuit prior to insertion into the system's cryogenic cold box. The need for a spare carbon bed at SNS due to the variability of carbon media lifetime calculation to adsorption efficiency will be discussed. The fabrication, installation and commissioning of this spare carbon vessel will be presented. The novel plan for connecting the spare carbon vessel piping to the existing infrastructure will be presented.

    2018-04-01

    Active magnetic regenerators (AMR) have the potential for high efficiency cryogen liquefaction. One active magnetic regenerative liquefier (AMRL) configuration consists of dual magnetocaloric regenerators that reciprocate in a persistent-mode superconducting solenoid. Issues with this configuration are the spatial and temporal magnetization gradients that induce large magnetic forces and winding currents. To solve the coupled problem, we present a force minimization approach using passive magnetic material to balance a dual-regenerator AMR. A magnetostatic model is developed and simulated force waveforms are compared with experimental measurements. A genetic algorithm identifies force-minimizing passive structures with virtually ideal balancing characteristics. Implementation details are investigated which affirm the potential of the proposed methodology.

    Full Text Available In spite of the government’s multilateral effort to control food safety, there have been constantly many shock events threatening citizens’ health. This paper points out the matter of food safety management system with a view of competition for jurisdiction over food industry among the Ministry of Health and Welfare and the Ministry for Food, Agriculture, Forestry and Fisheries and affiliated organizations. Use description qualitative method in research. Each ministry has separate basic positions and approaches to food industry policy: regulation and promotion.The policy image has been changed into “regulation” as public anxiety and concern for hazardous foods has grown since the end of 1990. They competeto take charge of promoting or regulating the food industry by establishing or amending laws, expanding organizations and mobilizing a coalition.Coordination by policy committee, cooperation between agencies, and integration of agencies were introduced as measures to eliminate unnecessary competition for jurisdiction.

  3. Jurisdictional Competition Between Private and Public Sector Auditors

    This paper explores the apparent paradox that while public sector auditors have become more powerful by claiming performance auditing expertise and linking this to New Public Management reforms, the same reforms have provided an opening for competition between private and public sector auditors....... In Denmark, the competitive relation has led to a jurisdictional dispute between public and private sector auditors in which the former have developed a special qualification for public sector auditors. The paper analyses the development of this qualification using Abbott's (1988) theory of the system...... of professions, thus focusing on how the involved groups have attempted to build networks of support for their competing jurisdictional claims of expertise. The case contributes to knowledge about the potential for development of a distinct public sector auditor identity. The case suggests that to develop...

    1987-01-01

    Gasoline and diesel fuel were produced from directly liquefied biomass (the PERC process) by: * Extraction of the crude liquefied oil with a diesel fuel type solvent at the atmospheric boiling point of the solvent. * Hydroprocessing of the extracted oil at 370 degrees C and 10 MPa with a suphided cobolt-molybdenum on gamma-Al{sub 2}O{sub 3} catalyst (Akzo Ketjen 742). * The hydroprocessed oil was distilled to produce gas, gasoline, gas oil and an atmospheric residue. * The residue was catalytically cracked to produce lighter products with a commercial catalyst (EKZ-2). The coke is produced in the catalytic cracking step and is used as an energy source in the catalytic cracker and elsewhere in the refinery. In the proposed refinery vacuum gas oil is recirculated through the hydroprocessing unit to improve the yields of transportation fuels. The residue from the extraction step is proposed to be used to meet needs for steam, hydrogen and carbon monoxide in liquefaction and upgrading. Hydrodeoxygenation of methyl-substituted phenols over Akzo Ketjen 742 as a catalyst proceeded by two parallel paths leading to an aromatic product and a naphthenic product, respectively, at the conditions used (300 degrees C, 5 MPa). Kinetic analysis showed both paths to be inhibited by reactant, addition of ammonia and hydrogen sulphide. Steric hindrance was observed, and two types of active sites were proposed to be responsible for the two paths. Oxygen in non-volatile organic materials was determined with a modified method on a LECO RO-116 oxygen determinator. (The thesis contains 8 papers and articles. 98 refs.).

  5. Conflicts of Criminal Jurisdiction in the European Union

    Directory of Open Access Journals (Sweden)

    Frank Zimmermann

    2015-07-01

    Full Text Available Conflicts of criminal jurisdiction between the Member States belong to the most difficult challenges that the European Union has to face in order to establish a true “area of freedom, security and justice”. This article starts with an analysis of the interests that are affected by such conflicts: on the one hand, they are most problematic for the individual because they can lead to repeated or simultaneous proceedings in different Member States and forum shopping by prosecution authorities. What is more, they can even make it impossible to foresee whether and how severely an act will be punished. Thus, essential criminal law and procedure guarantees like ne bis in idem, the principle of legality, the right to a court established by law as well as the right to an effective defence are jeopardised. On the other, the Member States involved often have a legitimate interest in prosecution—or non-prosecution—and risk to spend their financial and personnel resources for ineffective parallel proceedings. In order to avoid conflicts of criminal jurisdiction, various models are conceivable. However, the most convincing one—according to the author’s opinion—builds upon a combination of different elements: a hierarchy of jurisdictional links should form the basis, but it would have to be complemented with provisions allowing for more flexibility in precisely defined circumstances. With this in mind, this article calls for the adoption of an EU regulation in order to solve the most urgent problems arising from conflicts of criminal jurisdiction and makes concrete suggestions as to its drafting.

    Full Text Available Harmful tax competition is not just tax system, but can also undermine the interests of local communities and the environment. Tax havens are a huge drain of resources from other countries (basic non tax haven to offshore areas. To operate, tax havens are supported economically, politically, and socially by high tax states. Also, by encouraging savings, it boosts investment and capital formation. Because they are low tax jurisdictions, they exert a higher tax on tax rates worldwide.

  11. Considering marijuana legalization carefully: insights for other jurisdictions from analysis for Vermont.

    Science.gov (United States)

    Caulkins, Jonathan P; Kilmer, Beau

    2016-12-01

    In 2014 the legislature of Vermont, USA passed a law requiring the Secretary of Administration to report on the consequences of legalizing marijuana. The RAND Corporation was commissioned to write that report. This paper summarizes insights from that analysis that are germane to other jurisdictions. Translation of key findings from the RAND Corporation report to the broader policy debate. Marijuana legalization encompasses a wide range of possible regimes, distinguished along at least four dimensions: which organizations are allowed to produce and supply the drug, the regulations under which they operate, the nature of the products that can be distributed and taxes and prices. Vermont's decriminalization had already cut its costs of enforcing marijuana prohibition against adults to about $1 per resident per year. That is probably less than the cost of regulating a legal market. Revenues from taxing residents' purchases after legalization could be many times that amount, so the main fiscal cost of prohibition after decriminalization relative to outright legalization may be foregone tax revenues, not enforcement costs. Approximately 40 times as many users live within 200 miles of Vermont's borders as live within the state; drug tourism and associated tax revenues will be important considerations, as will be the response of other states. Indeed, if another state legalized with lower taxes, that could undermine the ability to collect taxes on even Vermont residents' purchases. Analysis of possible outcomes if Vermont, USA, legalized marijuana reveal that choices about how, and not just whether, to legalize a drug can have profound consequences for the effects on health and social wellbeing, and the choices of one jurisdiction can affect the options and incentives available to other jurisdictions. © 2016 Society for the Study of Addiction.

  13. Jurisdiction of courts with a focus on the Special Chamber of the Supreme Court of Kosovo

    Directory of Open Access Journals (Sweden)

    Mr.Sc. Sabri Halili

    2013-06-01

    Full Text Available The legal solution offered by the Law establishing the Special Chamber of the Supreme Court of Kosovo is rather challenging for practical implementation. Due to this fact, the decisions of the Special Chamber contain various dilemmas of judges on the jurisdiction of the Chamber on the matters related to natural persons sued by the PAK, which are related to various liabilities of these persons to socially-owned enterprises, namely to the PAK. Since the PAK administers and represents socially owned property in general, it is naturally bound to seek for legal resolutions for all legal contests before a competent court. Naturally, the PAK would seek for such a solution before the Special Chamber of the Supreme Court of Kosovo on PAK-related matters, which is already bound by the title itself, “on PAK-related matters”. Comparisons of remedies by various laws related to subject competence are based on legal literature used in higher education in Kosovo. Analysis of subject competences of regular and special courts is two-fold: the Commercial Court and the Military Court, while the competence of the Special Chamber is only analysed in relation with the Law on Courts, and the Law on the Special Chamber of the Supreme Court, comparing it with the Law on Contested Procedure and the Law on the PAK. The Special Chamber has before and still continues to avoid jurisdiction of this Court, which is sanctioned by Articles 4 and 5 of the Law on the Special Chamber, due to the fact that in cases in which the PAK has sued a natural or legal person, due to debts, occupation of socially owned property, or any other disputed matter, which is directly related to socially owned properties, the Special Chamber proclaims itself incompetent, and transfers the case to regular courts, although the Special Chamber adjudicates “on PAK-related matters”, but in this case only when the PAK is respondent, not when it is claimant.

    Directory of Open Access Journals (Sweden)

    V. V. Ananskikh

    2015-01-01

    Full Text Available Starch hydrolysis is main technological process in production of starch sweeteners. Acid hydrolysis of starch using hydrochloric acid is carried out very fast but it does not allow to carry out full hydrolysis and to produce products with given carbohydrate composition. Bioconversion of starch allows to eliminate these limitations. At production of starch sweeteners from starch using enzymes starch hydrolysis is carried out in two stages At first starch – starch liquefaction the rapid increase of viscosity takes place which requires intensive mixing. Liquefying station consists of jet-cooker, holder, pressure regulator and evaporator. Jet-cooker of starch is its main part, starch is quickly turns into soluble (gelatinized state and it is partially liquefied by injection of starch suspension by flow of water vapor under pressure not less than 0,8 MPa. Heat and hydraulic calculation were carried out in order to determine constructive sizes of mixer for cooking of starch. The main hydraulic definable parameters are pressure drop in mixer, vapor pressure at mixer inlet, daily capacity of station by glucose syrup M, product consumption (starch suspension, diameter of inlet section of vapor nozzle. The goal of calculation was to determine vapor consumption M1, diameter d2 of outlet section of confuser injector, length l2 of gelatinization section. For heat calculation there was used Shukhov’s formula along with heat balance equation for gelatinization process. The numerical solution obtained with adopted assumptions given in applied mathematical package MATHCAD, for M = 50 t/day gives required daily vapor consumption M1 = 14,446 т. At hydraulic calculation of pressure drop in mixer there was used Bernoulli’s theorem. Solving obtained equations using MATHCAD found diameter of outlet section of consufer d2 = 0,023 м, vapor pressure inside of mixer p2 = 3,966·105 Па, l2 = 0,128 м. Developed method of calculation is used to determine

  20. Evaluation of burn injuries related to liquefied petroleum gas.

    Science.gov (United States)

    Tarim, Mehmet Akin

    2014-01-01

    Liquefied petroleum gas (LPG) is a fuel that is widely used for domestic, agricultural, and industrial purposes. LPG is also commonly used in restaurants, industries, and cars; however, the home continues to be the main site for accidents. In Turkey, the increased usage of LPG as a cooking or heating fuel has resulted in many burn injuries from LPG mishaps. Between January 2000 and June 2011, 56 LPG-burned patients were compared with 112 flame-burned patients. There were no significant differences with respect to the mean age, sex, hospitalization time, and mortality in both groups. In the LPG-caused burn cases, 41 burns (73.2%) occurred at home, seven (12.5) were work-related mishaps, and eight (14.3) were associated with car accidents. The majority of the LPG burns (82%, 46 patients) resulted from a gas leak, and 18% of them were related to the failure to close LPG tubes in the patients' kitchens (10 patients). Burns to the face and neck (82 vs 67%, P = .039) and upper (62 vs 23%, P = .000) and lower (70 vs 45%, P = .002) extremities were significantly higher in LPG-caused burn cases than flame-burned cases. General awareness regarding the risk of LPG and first aid for burns appears to be lacking. The LPG delivery system should be standardized throughout countries that widely use LPG.

    Gray, H.E.

    1993-01-01

    The Liquefied Gaseous Fuels Spill Test Facility (STF) constructed at the Department of Energy's Nevada Test Site is a basic research tool for studying the dynamics of accidental releases of various hazardous liquids. This Facility is designed to (1) discharge, at a controlled rate, a measured volume of hazardous test liquid on a prepared surface of a dry lake bed (Frenchman Lake); (2) monitor and record process operating data, close-in and downwind meteorological data, and downwind gaseous concentration levels; and (3) provide a means to control and monitor these functions from a remote location. The STF will accommodate large and small-scale testing of hazardous test fluid release rates up to 28,000 gallons per minute. Spill volumes up to 52,800 gallons are achievable. Generic categories of fluids that can be tested are cryogenics, isothermals, aerosol-forming materials, and chemically reactive. The phenomena that can be studied include source definition, dispersion, and pool fire/vapor burning. Other capabilities available at the STF include large-scale wind tunnel testing, a small test cell for exposing personnel protective clothing, and an area for developing mitigation techniques

  2. Environmental hazards due to rupture of a liquefied propane pipeline

    International Nuclear Information System (INIS)

    Badr, O.A.; El-Sheikh, H.A.

    1996-01-01

    Accidental leakages of liquefied propane from high-pressure pipelines may occur despite the use of sophisticated safety equipment and following strict monitoring procedures. Environmental impact of steady and transient leakages were considered from toxicity and flammability viewpoints for two specific scenarios of full pipe ruptures. For each case, calculated mass flow rate, velocity, and temperature of leaking gas were utilized in an EPA-based dispersion model to predict the ground level concentration profiles in the downwind and crosswind directions. For the specific pipeline conditions considered here, the first scenario of a nonjet release (a cloud) produced steady toxic and flammable zones which were about 20 times bigger than those produced in the transient case. The second scenario of a free vertical jet resulted in the formation of a flammable vertical plume, while at ground level it did not produce flammable nor toxic zones. A parametric study of the first scenario confirmed the expected effects of both the gas release time and the atmospheric stability on the size of the dangerous zones. Within the typical range, the wind speed was found to have opposite effects for steady and transient releases. For a steady release, the dangerous zone was wider for slower winds and vice versa for a transient case. Moreover, the size of the dangerous zone was found to be an exponential function of the pipe diameter, while the effect of the initial pipe pressure was insignificant

    This article reviews the current legal status of abortion in Australia and its implications. Australian abortion law has been a matter for the states since before Federation. In the years since Federation there have been significant reforms and changes in the abortion laws of some jurisdictions, although not all. Across Australia there are now nine sets of laws, state and Commonwealth, concerned with abortion. The test of a lawful abortion varies greatly across jurisdictions. In a number of states and territories, it is necessary to establish a serious risk to the physical or mental health of the woman if the pregnancy was to continue. In some cases, the certification of two doctors is required, particularly for abortions at later gestations. There are also physical restrictions on access, such as in South Australia and the Northern Territory where abortion must take place in a hospital. Only in the ACT has abortion been removed from the criminal law altogether. Variations in the law and restrictions arising from these are not consistent with the aims and provision of the universal, accessible health care system aspired to in Australia. There is an urgent need for overall reform and the introduction of uniformity to Australia's abortion laws, including removal of abortion from the criminal law. © 2015 The Royal Australian and New Zealand College of Obstetricians and Gynaecologists.

    The first Administration-wide Quadrennial Energy Review (QER), released in April 2015, found that the “interacting and overlapping” division of authority between “federal, regional and state institutions and regulatory structures” for the electricity sector could “impede development of the grid of the future [and] . . . the development of markets that efficiently integrate” new and emerging technologies.1 While “technology is indifferent to state-Federal boundaries and jurisdictions,” the QER explained, “technology users cannot be.”2 The report concluded that “[b]oth Federal and state governments need to play constructive and collaborative roles in the future to ensure that consumers and industry are able to maximize the value of new technologies.”3 The QER recommended that the Department of Energy (“DOE”) facilitate such collaboration by playing a “convening role” to bring together state and federal regulators and other stakeholders to consider these issues.4 This paper provides background and analysis on these jurisdictional issues and the impact they may have on adoption of emerging energy technologies and coordination of markets for those technologies, in support of future dialogs on these subjects. In particular, this paper reviews the structure of the Federal Power Act (“FPA”),5 and compares the division of authority between the federal and state governments adopted there with other federal energy and energy-related statutes.

  5. Reforming the South African Social Security Adjudication System: Innovative Experiences from South African Non-Social Security Jurisdictions

    Full Text Available There is currently no uniform social security dispute resolution system in South Africa due to the piecemeal fashion in which schemes were established or protection against individual risks regulated. The result is that each statute provides for its own dispute resolution institution(s and processes. There are also various gaps and challenges in the current social security dispute resolution systems, some of these relating to the uncoordinated and fragmented nature of the system; inaccessibility of some social security institutions; inappropriateness of some current appeal institutions; the lack of a systematic approach in establishing appeal institutions; a limited scope of jurisdiction and powers of adjudication institutions; inconsistencies in review and/or appeal provisions in various laws; an unavailability of alternative dispute resolution procedures; and an absence of institutional independence of adjudication institutions or forums. The system is therefore in need of reform. In developing an appropriate system, much can be learned from innovative experiences in comparative South African non-social security jurisdictions on the establishment of effective and efficient dispute resolution frameworks. Dispute resolution systems in the labour relations, business competition regulation and consumer protection jurisdictions have been established to realise the constitutional rights of their users (especially the rights of access to justice, to a fair trial and to just administrative action. They thus provide a benchmark for the development of the South African social security dispute resolution system.

    Liquefied petroleum gas (LPG) cookstoves are considered to be an important solution for mitigating household air pollution; however, their performance has rarely been evaluated. To fill the data and knowledge gaps in this important area, 89 laboratory tests were conducted to quantify efficiencies and pollutant emissions from five commercially available household LPG stoves under different burning conditions. The mean thermal efficiency (±standard deviation) for the tested LPG cookstoves was 51 ± 6%, meeting guidelines for the highest tier level (Tier 4) under the International Organization for Standardization, International Workshop Agreement 11. Emission factors of CO 2 , CO, THC, CH 4 , and NO x on the basis of useful energy delivered (MJ d ) were 142 ± 17, 0.77 ± 0.55, 130 ± 196, 5.6 ± 8.2, and 46 ± 9 mg/MJ d , respectively. Approximately 90% of the PM 2.5 data were below the detection limit, corresponding to an emission rate below 0.11 mg/min. For those data above the detection limit, the average emission factor was 2.4 ± 1.6 mg/MJ d , with a mean emission rate of 0.20 ± 0.16 mg/min. Under the specified gas pressure (2.8 kPa), but with the burner control set to minimum air flow rate, less complete combustion resulted in a visually yellow flame, and CO, PM 2.5 , EC, and BC emissions all increased. LPG cookstoves met guidelines for Tier 4 for both CO and PM 2.5 emissions and mostly met the World Health Organization Emission Rate Targets set to protect human health.

  7. THE ORGANIZATION OF JURISDICTION IN EUROPEAN UNION PERSPECTIVE

    Full Text Available Nowadays, universal jurisdiction is the favorite technique used to prevent impunity for international crimes and it is one of the most effective methods to deter and prevent international crimes by increasing the like hood of prosecution and punishment of its propagators. In regard to the defendants’ rights, the European Union states consider applicable all the rights that are necessary to assure that the trial is equitable and expeditious. There is no exception to the right to a fair trial. So, a defendant who is being prosecuted on the basis of the universality principle can rely on all the procedural rights provided for the Convention on Human Rights and the domestic code of criminal procedure without any restrictions. In Germany, the Federal Constitutional Court, in a case concerning genocide committed abroad, declared expressly that no special criminal proceedings must be provided for specific crimes.

  8. Hageseth's principle of extraterritorial jurisdiction and international telemedicine.

    2008-01-01

    At what point does an international telemedicine transaction create a sufficient commercial nexus to allow one country the authority to impose its laws on a foreign telemedicine providers? Some light on this matter was shed by the US case of Hageseth versus Superior Court. The authority for extraterritorial jurisdiction is found in the US Constitution, which requires the states to cooperate in matters of law enforcement. Similar cooperation from foreign nations cannot be expected. Unless a defendant is charged with a capital offence, nations are rarely willing to extradite their citizens. As the unlicensed practice of medicine is not a capital offence, it is unlikely that an unlicensed telemedicine provider would be extradited to the US. Because low-volume unlicensed offshore telemedicine providers are unlikely to be extradited or to be subject to trade sanctions, they may be able to operate beyond the law.

    Full Text Available According to the United Nations, our world is becoming more populated, more urban, more connected, more globalized, and more complex. With this physical and social complexity comes a need for increased coordination in negotiating our urban futures. Environmental design and planning professionals have worked for decades according to traditional institutionalized role structures. Sustainability—in considering a wider variety of stakeholders—promises not only to include more members in the typical design and construction team (e.g., sustainability consultants, community representatives, technical specialists, etc., but also to change the jurisdiction of tasks (e.g., project management, decision making, design leadership, etc. taken on by actors in traditional roles (e.g., owner, architect, contractor, etc.. This paper examines how a wider social concern for environmental and social sustainability has affected the design and construction industry. Organizational and sociological theories suggest that professions are “bound to a set of tasks by ties of jurisdiction... [P]rofessions make up an interacting system... and a profession’s success reflects as much the situations of its competitors and the system structure as it does the profession’s own efforts” (Abbott 1988: 33. Abbott also suggests that “larger social forces” affect the structuring of professional boundaries. Treating sustainability as a “larger social force,” this paper examines current understandings of professional boundaries in the planning, design, and construction of our environments. It answers questions of how professionals renegotiate roles, responsibilities, and compensation when dealing with an uncertain change in traditional processes.The qualitative data stem from three university building projects. Each project was proposed ab initio without a mandate to achieve LEED Certification, but this complex criterion was subsequently added at different phases of

    The present studies are intended to study catalysts that make manufacture of liquid fuel possible through coal liquefying reactions, and establish a liquefied oil analyzing method. The following items are discussed based on the achievements obtained by fiscal 1985: in the studies on coal liquefying catalysts, (1) a study on selectively liquefying catalysts, in which elucidation is made on effects of catalyst carriers on reaction selectivity and life of coal liquefying catalysts, and fundamental data are accumulated toward designing the catalysts with respect to catalyst carriers capable of selective hydrogenating reactions, and to carrying conditions; and (2) a study on solvent properties and reaction conditions. in which Mo-based catalysts are used to perform kinetic discussions on the relationship between the liquefying reaction conditions and compositions of solvents and produced oil to accumulate data for elucidating the action mechanisms of the Mo-based catalysts. In the study of the liquefied oil analyzing method, discussions are carried out on a measuring technology to expand the conventional method for liquefied oil analysis to hard-to-volatilize components. For the light and medium oils, an analyzing method will be established that utilizes effectively the NMR method and the MS method that have been established to date. (NEDO)

  12. Jurisdiction by Necessity and the Regulation of the Transnational Corporate Actor

    Directory of Open Access Journals (Sweden)

    Chilenye Nwapi

    2014-02-01

    Full Text Available This article examines the feasibility of using the jurisdiction by necessity doctrine to promote the accountability of transnational corporations (TNCs for extraterritorial human and environmental rights abuses committed in developing countries with weak accountability mechanisms. Under the doctrine, a court devoid of jurisdiction may nevertheless hear a dispute where it considers that there is no other court where the dispute may be heard or where the plaintiff may be reasonably expected to bring the action. The article analyzes the inadequacy of existing jurisdictional doctrines in light of the complex web of operations of TNCs, which shields them from the reach of traditional jurisdictional doctrines. After exploring the origin of the jurisdiction by necessity doctrine, the article critically examines the elements of the doctrine to see how they may be applied to the regulation of TNCs. The article argues that the emergence of the jurisdiction by necessity doctrine offers plaintiffs in transnational corporate human rights litigation a new jurisdictional possibility to weigh, as the doctrine has the potential to address some of the jurisdictional difficulties encountered in such litigation.

El material, tanto fresco como usado, se caracterizó mediante DRX, área superficial BET y SEM-EPMA. El catalizador mostró una matriz de MgO tipo periclasa con CaO en la superficie. Las pruebas de actividad catalítica se efectuaron en lecho fijo empacado con partículas obtenidas mediante prensado, trituración y clasificación del material. El flujo de reactivos consistió en mezclas gas natural-aire por debajo del límite inferior de inflamabilidad. Para diferentes flujos y temperaturas de entrada de la mezcla reactiva, se midieron las concentraciones de CH4, CO2 y CO en los gases de combustión con un analizador de gases tipo infrarrojo no dispersivo (NDIR. Para alcanzar conversión total de metano se requirió aumentar la temperatura de entrada al lecho a medida que se incrementó el flujo de gases reaccionantes. Los resultados obtenidos permiten desarrollar un sistema de combustión catalítica de bajo costo con un material térmicamente estable, que promueva la alta eficiencia en la combustión de gas natural y elimine los problemas de estabilidad, seguridad y de impacto ambiental negativo inherentes a los procesos de combustión térmica convencional.

  2. Assessment of potential radiological population health effects from radon in liquefied petroleum gas

    Energy Technology Data Exchange (ETDEWEB)

    Gesell, Thomas F; Johnson, Jr, Raymond H; Bernhardt, David E

    1977-02-01

    Liquefied petroleum gas (LPG) contains varying amounts of radon-222 which becomes dispersed within homes when LPG is used in unvented appliances. Radon-222 decays to alpha-emitting daughter products which are associated with increased lung cancer when inhaled and deposited in the respiratory system. The average dose equivalents to the bronchial epithelium from the use of LPG in unvented kitchen ranges and space heaters are estimated to be about 0.9 and 4.0 mrem/year, respectively. When extrapolated to the United States population at risk, the estimated tracheobronchial dose equivalents are about 20,000 and 10,000 person-rems/year for these appliances, or a total of about 30,000 person-rems/year. These doses are very small compared to other natural and man-made sources of ionizing radiation. It is estimated that these low doses would result in less than one lung cancer a year for the total U.S. population. Consequently, the use of LPG containing radon-222 does not contribute significantly to the incidence of lung cancer in the United States. Furthermore, the cost for control of radon levels in LPG would be over $50 million for reduction of one health effect, therefore it is concluded that a requirement for such controls would not be cost effective on a national basis. This study did indicate that individual dose equivalents could possibly exceed 500 mrem/year. However, existing data are not sufficient to determine the significance of such potentially high individual doses. (author)

  3. Assembly of cell-laden hydrogel fiber into non-liquefied and liquefied 3D spiral constructs by perfusion-based layer-by-layer technique

    Sher, Praveen; Oliveira, Sara M; Borges, João; Mano, João F

    2015-01-01

    In this work, three-dimensional (3D) self-sustaining, spiral-shaped constructs were produced through a combination of ionotropic gelation, to form cell-encapsulated alginate fibers, and a perfusion-based layer-by-layer (LbL) technique. Single fibers were assembled over cylindrical molds by reeling to form spiral shapes, both having different geometries and sizes. An uninterrupted nanometric multilayer coating produced by a perfusion-based LbL technique, using alginate and chitosan, generated stable 3D spiral-shaped macrostructures by gripping and affixing the threads together without using any crosslinking/binding agent. The chelation process altered the internal microenvironment of the 3D construct from the solid to the liquefied state while preserving the external geometry. L929 cell viability by MTS and dsDNA quantification favor liquefied 3D constructs more than non-liquefied ones. The proposed technique setup helps us to generate complex polyelectrolyte-based 3D constructs for tissue engineering applications and organ printing. (note)

    Full Text Available This paper represents the outcome of research fellowship Marie Curie at the Universiteit Leiden -Campud Den Haag Grotius, Centre for International Legal Studies (prof. C. Stahn and prof. Larissa van den Herik, supervisors on the topic "The Fragmentation and the Diversification of International Criminal Law in a Global Society”.In my paper I will examine the question of whether Universal Jurisdiction (UJ leads to unity or fragmentation within International Criminal Law (ICL. Given that there is already quite a lot of literature on UJ, it is important to focus the research on the issue of fragmentation and/or unity rather than to deal with the issue of UJ more generally. I will focus on this topic in sections 1 and 2, explaining some cursory remarks to these issues in my analysis on fragmentation. In the introduction, I will briefly introduce UJ as a controversial form of jurisdiction, but still necessary given that territorial jurisdiction does not always function well in the case of international crime. I will demonstrate that many state parties to the International Criminal Court (ICC Statute have vested or reconfirmed UJ for the core crimes when implementing the ICC Statute. The leading question of my research is whether this practice has led or has the potential to lead to unity or rather to fragmentation within ICL. In the research I will approach this question from different perspectives.In section 1 I will examine how State parties have may actually enacted universal jurisdiction for the core crimes, with a view to determining whether there is indeed some unity on this front or whether the practice on this matter is actually rather diverse (or fragmented. Subsequently, I will analyse which conditions States have formulated for the exercise of UJ, and whether this practice is consistent (unity or again rather diverse (fragmentation. It might also be interesting to see whether States have different conditions for UJ over core crimes than

    2008-01-01

    Recent studies in Japan have suggested that natural gas hydrate (NGH) transportation of natural gas is more economical than liquefied natural gas (LNG) transportation systems for small, medium and remote gas fields. Researchers in Japan have built a 600 kg per day NGH production and pelletizing plant and regasification facility. This paper discussed feasibility studies conducted in southeast Asia to determine the unit's commercialization potential with large natural gas-related businesses including shipping companies and electric power utilities. The total supply chain was compared with the corresponding liquefied natural gas (LNG) and compressed natural gas (CNG) supply chains. The study also examined natural gas reserves, energy policies, the positioning of natural gas supplies, and future forecasts of natural gas demand. A conceptual design for an NGH supply chain in Indonesia was presented. Results of the study have demonstrated that the NGH chain is an appropriate and economically feasible transportation method for many areas in southeast Asia. 8 refs., 10 figs

    Liquefactions of kenaf core wood were carried out at different phenol-kenaf (P/ k) ratios. Characterizations of kenaf core wood liquefied residue were carried out to measure the degree of liquefaction. This provides a new approach to understand some fundamental aspects of the liquefaction reaction. Functional groups on the raw kenaf core wood and liquefied residue were examined using Fourier transform infrared spectroscopy (FTIR). The crystallinity index of the kenaf wood liquefied residue, which represents crystallinity changes of the cellulose component after the liquefaction process, was studied using X-ray diffraction (XRD). The surface morphology of the wood residue was observed using scanning electron microscopy (SEM). The thermal behavior of the residues was analyzed using thermogravimetric analysis (TGA). Abroad peak around 3450-3400 cm -1 representing OH stretching in lignin start to disappear as P/K ratio increases. The results showed that the higher the P/K ratio the greater the liquefaction of the lignin component in the kenaf core wood. The crystallinity index (CrI) on the kenaf liquefied residues increased with the increase in P/K ratio. SEM images showed that the small fragments attached on the liquefied kenaf residue surface were gradually removed as the P/K ratio was increased from 1.5/ 1.0 to 2.5/ 1.0, which is mainly attributed to the greater chemical penetration toward reactive site of the kenaf fibres. Residue content decreased as the P/K ratio increased from 1.5/ 1.0 to 2.5/ 1.0. TGA results showed the increase of heat resistance in the residue as the P/K ratio was increased. (author)

    Generally, the temperature drop under 0 .deg. C on vaporizer surface creates frozen dews. This problem seems to increase as the time progress and humidity rises. In addition, the frozen dews create frost deposition. Consequently, heat transfer on vaporizer decreases because frost deposition causes adiabatic condition. Therefore, it is very important to solve this problem. This paper aims to study of the optimum design of used vaporizer at local LNG station. In this paper, experimental results were compared with numerical results. Geometries of numerical and experimental vaporizers were identical. Studied parameters of vaporizer are angle between two fins (Φ) and fin thickness (TH F ). Numerical analysis results were presented through the correlations between the ice layer thickness (TH ICE ) on the vaporizer surface to the temperature distribution of inside vaporizer (T IN ), fin thickness (TH F ), and angle between two fins (Φ). Numerical result shows good agreement with experimental outcome. Finally, the correlations for optimum design of vaporizer are proposed on this paper

  16. Comparison of the key mechanisms leading to rollovers in Liquefied Natural Gas using Computational Fluid Dynamics

    Growing demand for the LNG fosters growth of the number of production sites with varying composition and density. Combining different sources of LNG may result in a stably stratified system, in which heat and mass transfer between the layers is limited. Heating of the LNG due to wall thermal conductivity leads to formation of convection cells confined within the layers. While the upper layer can release the extra energy via preferential methane boil-off, the bottom layer cannot and hence becomes superheated. Gradual density equilibration reduces stratification and may eventually lead to a sudden mixing event called ``rollover'', accompanied by violent evaporation of the superheated LNG. Three phenomena are potentially responsible for density equilibration. The first is the growing difference in thermal expansion of the layers due to the reduced ability of the bottom layer to reject heat. The second is the penetration of the heated near-wall boundary layer into the upper layer. The third is the ``entrainment mixing'' occurring at the contact surface between the two layers. The present study uses CFD to compare these mechanisms. Boussinesq approximation and an extended version of the k- ɛ model is used. The code is validated by comparison with a large-scale LNG rollover experiment.

    Yepes Rodriguez, Ramon

    2008-01-01

    This paper presents a real option model for the valuation of destination flexibility in long-term LNG supplies. Stochastic price dynamics in the different markets is modelled through geometric Brownian motion processes. Mean reversion is considered as well as correlation between markets, but instead of the usual correlation in return shocks, a price convergence term is introduced representing the arbitrage streams between markets. Model parameters are estimated from market data on LNG prices by maximum log-likelihood. The goodness of the fit for the proposed model is tested as well as for two alternative models. Confidence intervals for the parameters are given. Results for the model are calculated by Monte Carlo simulation. Frequency distributions for the main results are plotted. The effect of the main parameters of the model is studied (i.e. price volatilities, price convergence, initial prices in the markets, mean reversion, extra transportation costs, number of alternative markets). The value of destination flexibility is found to be an important share of the value of LNG

Con sus demandas, el Jeque Shakhbout forzaba a la burocracia a cargo de los Estados de la Tregua – La Oficina de Asuntos Extranjeros en Londres, el representante del gobierno Británico en Bahreín, y los agente administrativos y políticos en Dubai y Abu Dhabi a reexaminar las bases legales de la presencia Británica en la zona y los límites éticos del sistema judicial impuesto sobre sus habitantes. La crisis va mas allá de una discusión sobre los poderes jurisdiccionales. La crisis nos ofrece una ventana a las contradicciones inherentes a la  presencia Británica en la zona, en el marco del movimiento nacionalista árabe y del desarrollo de la industria petrolera y la futura redefinición de la relación entre Abu Dhabi  y la Gran Bretaña.Palabras clave: Abu Dhabi, Gran Bretaña, colonialismo___________________________Abstract:Demands to the British government for supreme jurisdiction over his territory presented by the ruler of Abu Dhabi in 1959 created a diplomatic crisis captured in the internal correspondence of the British government.

This paper proposes to define the significance of liquefied natural gas in gas exchanges and it analyses the problem of European gas vulnerability using several indicators

  10. Mandatory Reporting Laws and Identification of Child Abuse and Neglect: Consideration of Differential Maltreatment Types, and a Cross-Jurisdictional Analysis of Child Sexual Abuse Reports

    Directory of Open Access Journals (Sweden)

    Ben Mathews

    2014-08-01

    Full Text Available Mandatory reporting laws have been created in many jurisdictions as a way of identifying cases of severe child maltreatment on the basis that cases will otherwise remain hidden. These laws usually apply to all four maltreatment types. Other jurisdictions have narrower approaches supplemented by differential response systems, and others still have chosen not to enact mandatory reporting laws for any type of maltreatment. In scholarly research and normative debates about mandatory reporting laws and their effects, the four major forms of child maltreatment—physical abuse, sexual abuse, emotional abuse, and neglect—are often grouped together as if they are homogenous in nature, cause, and consequence. Yet, the heterogeneity of maltreatment types, and different reporting practices regarding them, must be acknowledged and explored when considering what legal and policy frameworks are best suited to identify and respond to cases. A related question which is often conjectured upon but seldom empirically explored, is whether reporting laws make a difference in case identification. This article first considers different types of child abuse and neglect, before exploring the nature and operation of mandatory reporting laws in different contexts. It then posits a differentiation thesis, arguing that different patterns of reporting between both reporter groups and maltreatment types must be acknowledged and analysed, and should inform discussions and assessments of optimal approaches in law, policy and practice. Finally, to contribute to the evidence base required to inform discussion, this article conducts an empirical cross-jurisdictional comparison of the reporting and identification of child sexual abuse in jurisdictions with and without mandatory reporting, and concludes that mandatory reporting laws appear to be associated with better case identification.

  11. FIRST OPERATING RESULTS OF A DYNAMIC GAS BEARING TURBINE IN AN INDUSTRIAL HYDROGEN LIQUEFIER

    Bischoff, S.; Decker, L.

    2010-01-01

    Hydrogen has been brought into focus of industry and public since fossil fuels are depleting and costs are increasing dramatically. Beside these issues new high-tech processes in the industry are in need for hydrogen at ultra pure quality. To achieve these requirements and for efficient transportation, hydrogen is liquefied in industrial plants. Linde Gas has commissioned a new 5.5 TPD Hydrogen liquefier in Leuna, Germany, which has been engineered and supplied by Linde Kryotechnik. One of the four expansion turbines installed in the liquefaction process is equipped with dynamic gas bearings. Several design features and operational characteristics of this application will be discussed. The presentation will include results of efficiency and operational reliability that have been determined from performance tests. The advantages of the Linde dynamic gas bearing turbine for future use in hydrogen liquefaction plants will be shown.

    Worldwide, excessive salt consumption is common and is a leading cause of high blood pressure. Our objectives were to assess the overall and differential impact (by social and economic indicators) of population-level interventions for dietary sodium reduction in government jurisdictions worldwide. This is a Cochrane systematic review. We searched nine peer-reviewed databases, seven grey literature resources and contacted national programme leaders. We appraised studies using an adapted version of the Cochrane risk of bias tool. To assess impact, we computed the mean change in salt intake (g/day) from before to after intervention. Fifteen initiatives met the inclusion criteria and 10 provided sufficient data for quantitative analysis of impact. Of these, five showed a mean decrease in salt intake from before to after intervention including: China, Finland (Kuopio area), France, Ireland and the UK. When the sample was constrained to the seven initiatives that were multicomponent and incorporated activities of a structural nature (e.g. procurement policy), most (4/7) showed a mean decrease in salt intake. A reduction in salt intake was more apparent among men than women. There was insufficient information to assess differential impact by other social and economic axes. Although many initiatives had methodological strengths, all scored as having a high risk of bias reflecting the observational design. Study heterogeneity was high, reflecting different contexts and initiative characteristics. Population-level dietary sodium reduction initiatives have the potential to reduce dietary salt intake, especially if they are multicomponent and incorporate intervention activities of a structural nature. It is important to consider data infrastructure to permit monitoring of these initiatives. © The Author 2017; all rights reserved.

    . Population-level interventions in government jurisdictions for dietary sodium reduction have the potential to result in population-wide reductions in salt intake from pre-intervention to post-intervention, particularly if they are multi-component (more than one intervention activity) and incorporate intervention activities of a structural nature (e.g. food product reformulation), and particularly amongst men. Heterogeneity across studies was significant, reflecting different contexts (population and setting) and initiative characteristics. Implementation of future initiatives should embed more effective means of evaluation to help us better understand the variation in the effects.

  18. The Universal Jurisdiction of South African Criminal Courts and Immunities of Foreign State Officials

    Directory of Open Access Journals (Sweden)

    Evode

    2015-12-01

    Full Text Available Under the "complementarity" regime of the Rome Statute of the International Criminal Court (ICC, the jurisdiction of the ICC is secondary to the jurisdiction of domestic courts. States Parties, not the ICC, have the primary responsibility of investigating and prosecuting international crimes. The ICC acts only when States are "unable" or "unwilling" to prosecute. As a State Party, in order to give effect to the complementarity principle, South Africa enacted the Implementation of the Rome Statute of the International Criminal Court Act 27 of 2002, which determines the modalities of prosecuting perpetrators of the crimes of genocide, crimes against humanity and war crimes in South African courts. The Implementation Act also provides that South African courts will have jurisdiction over these crimes not only when they are committed on the territory of South Africa but also when they are committed outside the Republic. By granting South African courts jurisdiction over a person who commits a crime outside the Republic when that person is later found on South African territory, without regard to that person's nationality or the nationality of the victims, the Implementation Act empowers South African courts with universal jurisdiction over international crimes. This paper seeks to determine whether and to what extent foreign State officials, such as foreign heads of State, heads of government and ministers of foreign affairs, can plead immunity when they are accused of international crimes before South African courts when exercising their universal jurisdiction in terms of the Implementation Act and in accordance with the complementarity regime of the Rome Statute. In other words, the article endeavours to determine whether international law rules regarding immunities of State officials may or may not limit the ability of South African courts to exercise universal jurisdiction over international crimes committed in foreign States.

  19. Towards Uniformity of Radiation Protection Legislation in a Multi-jurisdictional country- the Australian Experience

    International Nuclear Information System (INIS)

    Koperski, J. G.

    2004-01-01

    Australia is a federation of nine jurisdictions, each with independent radiation protection legislation. The existing legislative non-uniformity across the jurisdictions has constituted an impediment for operators who must comply with differing legislative requirements in different jurisdictions. To address this issue, a National Competition Policy Review of Radiation Protection Legislation took place in 2000/2001. It has produced 19 Recommendations, which addressed objectives of the legislation, the need to regulate, alternative regulatory approaches, national uniformity, licensing and registration, strict and prescriptive standards, advertising and promotional activities, compliance costs and cost recovery issues. The Review has recommended that jurisdictions should retain the regulatory approach to achieve radiation protection objectives rather than leave them to be decided by market forces. But the approach should be performance-based, i.e. outcome-focused rather than prescriptive. An Implementation Plan of the Recommendations has been created which, by the end of 2004, will produce the National Directory for Radiation Protection. The Directory, which will become a consolidated repository of radiation protection standards, guidelines, codes of practice and administrative principles will provide a uniform national framework for radiation protection legislation in Australia. It will provide guidance for the jurisdictions redrawing their legislations. Because of its central role in shaping future legislation, the Directory will contain only those provisions, which have passed a formal process (process for issue resolution) concluded by an approval by the Australian Health Ministers Conference. Such process will also expedite the uniform adoption nationwide of legislative trends emerging from international radiation protection recommendations and standards. This Australian model might be a viable example for other multi-jurisdictional countries to consider

  20. Provisions on waiting periods in international investment protection treaties and their impact on the jurisdiction of arbitral tribunals

    Directory of Open Access Journals (Sweden)

    Đundić Petar

    2012-01-01

    Full Text Available Provisions on so-called waiting periods in international investment protection treaties give an investor from one contracting state an opportunity to initiate arbitration against the host state provided that the time designated by the treaty from the date on which the dispute arose has elapsed. The aim of those provisions is to enable parties to the dispute to use this time for consultations and attempt to reach a negotiated settlement. The paper analyzes the attitude of contemporary arbitral practice towards the legal nature and effect of those provisions on tribunals' jurisdiction in investment disputes. The analysis shows gradual and clear shift of position taken by the tribunals in cases in which claimants did not comply with waiting periods. Because arbitral tribunals today are more resolved to penalize premature submission of the dispute to arbitration than they were one decade ago, in the future one can expect much more cautious conduct of potential claimants in this regard.

    The oil and natural gas exploitation in the Exclusive Economic Zone will propel the economy of the country, states and municipalities, due to tax revenues, jobs creation. It will also attract new businesses needed to support all the demand created by the main service and correlates. The Tax Service, under the municipal jurisdiction, is a major source of revenue. As the services are performed on the high seas and there is no law to regulate the territorial extent of each municipality, it can be argued that certain Artificial Island (oil platform, for example) is located within the extension of municipal sovereignty, which will allow the ISS taxation, problems will arise. This paper addresses these problems. (author)

    Full Text Available The Constitution of Colombia provides that certain senior officials, because of their position, should be investigated and tried by the Supreme Court (members of Congress or by the same Court upon indictment by the General Attorney (art. 235 n. 4. The Constitution provides that the President, the judges of the high courts and the prosecutor also have a special status, as the investigation and prosecution is allocated in the Senate, previous accusation in the House of Representatives, and in the Supreme Court for the common crimes. The criminal and disciplinary jurisdiction of investigation and prosecution has generated countless controversies at the doctrinal and jurisprudential level, related to the exclusive competence of the Prosecutor General’s Office and the judges of the Supreme Court to advance the investigation. In particular, the impossibility of delegating the commission of evidence and proceedings related to jurisdiction in such processes; the courts and their relationship with the position or function; the retention or recovery of competition by the criminal court room after renouncing the jurisdiction in the parapolitics processes; the notion tenure as a basis for criminal jurisdiction in the case of the governors in charge; a second hearing as a minimum guarantee derived from international standards on human rights and the issue related to jurisdiction and impunity on the subject of political or “impeachment” judgments.

  3. The res judicata rule in jurisdictional decisions of the international Court of justice

    Directory of Open Access Journals (Sweden)

    Kreća Milenko

    2014-01-01

    Full Text Available The author discusses the effects of the res judicata rule as regards jurisdictional decisions of the International Court of Justice. He finds that there exists a special position of a judgment on preliminary objection in respect to both aspects of the res judicata rule - its binding force and finality. A perception of distinct relativity of a jurisdictional decision of the Court, expressing its interlocatory character pervades, in his opinion, the body of law regulating the Court's activity. Preliminary objections as such do not exhaust objections to the jurisdiction of the Court, as evidenced by non-preliminary objections to the jurisdiction of the Court giving rise to the application of the principle compétence de la compétence understood in the narrow sense. With regard to the binding force of a judgment on preliminary objections, it does not create legal obligations stricto sensu. The author finds that the relative character of jurisdictional decisions of the Court as compared with a judgment on the merits is justified on a number of grounds.

    Full Text Available Special jurisdiction in matters of contracts is based on the close link between the cause of action and the territory of the court on which the jurisdiction is conferred. This is exception to the general jurisdiction based on defendant's domicile. It is introduced to legal systems with aims to facilitate the sound administration of justice and to make the balance between parties, giving the plaintiff a choice to bring proceedings to a court of his convenience. The structure of special jurisdiction rules contained in Brussels I Regulation is very complex. The general rule disguises more than it reveals at first glance and ought to be read in the light of the previous judgments of the ECJ and special rule is the modernizing element as it introduces an autonomous fact-based concept for the most important categories of contracts. After adoption of the new Serbian Law on International Private Law the rules on special jurisdiction shall be applied in accordance with EU standards, i.e. with ECJ practice.

  7. Deep-sea genetic resources: New frontiers for science and stewardship in areas beyond national jurisdiction

    Harden-Davies, Harriet

    2017-03-01

    The deep-sea is a large source of marine genetic resources (MGR), which have many potential uses and are a growing area of research. Much of the deep-sea lies in areas beyond national jurisdiction (ABNJ), including 65% of the global ocean. MGR in ABNJ occupy a significant gap in the international legal framework. Access and benefit sharing of MGR is a key issue in the development of a new international legally-binding instrument under the United Nations Convention on the Law of the Sea (UNCLOS) for the conservation and sustainable use of marine biological diversity in ABNJ. This paper examines how this is relevant to deep-sea scientific research and identifies emerging challenges and opportunities. There is no internationally agreed definition of MGR, however, deep-sea genetic resources could incorporate any biological material including genes, proteins and natural products. Deep-sea scientific research is the key actor accessing MGR in ABNJ and sharing benefits such as data, samples and knowledge. UNCLOS provides the international legal framework for marine scientific research, international science cooperation, capacity building and marine technology transfer. Enhanced implementation could support access and benefit sharing of MGR in ABNJ. Deep-sea scientific researchers could play an important role in informing practical new governance solutions for access and benefit sharing of MGR that promote scientific research in ABNJ and support deep-sea stewardship. Advancing knowledge of deep-sea biodiversity in ABNJ, enhancing open-access to data and samples, standardisation and international marine science cooperation are significant potential opportunity areas.

    In this work, the states law corresponding to flow rate measurements of two-phase flows performed with five different fluid (water, butane, R11, ethyl acetate, methanol) is applied. This allows to show that the critical mass flux (which is used as source term in the scenario of loss of confinement in liquefied gas reservoirs) is a 'universal' function of the reduced initial pressure P{sub 0}{sup *}, which can be used for most of the single-constituent fluids of the processes industry. Thus it is easy to make a relatively precise estimation of the critical mass flux (uncertainty < 20% for P{sub 0}{sup *} < 15%) without the need of any model. It is shown also that no improvement of the models can be expected from the use of the vaporization kinetics. On the contrary, a qualitative consideration indicates that the use of the slip seems more promising. (J.S.)

    Two autopsy cases of men who died while connecting a liquefied petroleum gas (LPG) pipe are reported. Their blood concentrations of propane (the main content of LPG) were 0.12 and 3.40 mg/100 g, respectively. The cause of death after exposure of LPG has generally been considered to be asphyxia from hypoxia. The large differences in the blood propane levels found here and reported in the literature, however, suggest that direct toxic effects of propane poisoning may be the cause of death in some cases. Propane concentrations and the cause of death are reviewed and discussed.

    This presentation described the framework of issues defining the effectiveness of inter-jurisdictional power transactions with reference to open market competition in Ontario and the current FERC initiative affecting transactions with adjacent markets in the United States. The opportunities and risks associated with inter-jurisdictional power transactions were pointed out, along with the interplay between forward and balancing markets. The future of the Regional Transmission Organizations (RTOs) and standard market design were also described. Inter-jurisdictional transactions were described as being a fundamental element of power markets in North America where consumers benefit from reliable supply and cost efficiency. Locational value of the delivered energy is reflected in transparent price which is determined by supply and demand. The efficient balancing markets promote liquid forward markets, as well as investment in power generation and transmission. Price risk is managed through market-based mechanisms by load-serving companies and capable consumers. Opportunities for Ontario buyers include increased reliability, increased competition among suppliers, and market drivers for demand response and innovation. Opportunities for suppliers include additional customers, hedge transactions across jurisdictions, and portfolio strategies. Opportunities for risk managers include broader, more liquid markets for standard products, robust markets for energy-linked commodities, and an increased need for customized, highly-structured financial products. 11 figs.

    2013-01-01

    Full Text Available Abstract Background Confidential product listing agreements (PLAs negotiated between pharmaceutical manufacturers and individual health care payers may contribute to unwanted price disparities, high administrative costs, and unequal bargaining power within and across jurisdictions. In the context of Canada’s decentralized health system, we aimed to document provincial policy makers’ perceptions about collaborative PLA negotiations. Methods We conducted semi-structured telephone interviews with a senior policy maker from nine of the ten Canadian provinces. We conducted a thematic analysis of interview transcripts to identify benefits, drawbacks, and barriers to routine collaboration on PLA negotiations. Results Canadian policy makers expressed support for joint negotiations of PLAs in principle, citing benefits of increased bargaining power and reduced inter-jurisdictional inequities in drug prices and formulary listings. However, established policy institutions and the politics of individual jurisdictional authority are formidable barriers to routine PLA collaboration. Achieving commitment to a joint process may be difficult to sustain among heterogeneous and autonomous partners. Conclusions Though collaboration on PLA negotiation is an extension of collaboration on health technology assessment, it is a very significant next step that requires harmonization of the outcomes of decision-making processes. Views of policy makers in Canada suggest that sustaining routine collaborations on PLA negotiations may be difficult unless participating jurisdictions have similar policy institutions, capacities to implement coverage decisions, and local political priorities.

    2016-01-01

    Local health departments (LHDs) are striving to meet public health needs within their jurisdictions, amidst fiscal restraints and complex dynamic environment. Resource sharing across jurisdictions is a critical opportunity for LHDs to continue to enhance effectiveness and increase efficiency. This research examines the extent of cross-jurisdictional resource sharing among LHDs, the programmatic areas and organizational functions for which LHDs share resources, and LHD characteristics associated with resource sharing. Data from the National Association of County & City Health Officials' 2013 National Profile of LHDs were used. Descriptive statistics and multinomial logistic regression were performed for the 5 implementation-oriented outcome variables of interest, with 3 levels of implementation. More than 54% of LHDs shared resources such as funding, staff, or equipment with 1 or more other LHDs on a continuous, recurring basis. Results from the multinomial regression analysis indicate that economies of scale (population size and metropolitan status) had significant positive influences (at P ≤ .05) on resource sharing. Engagement in accreditation, community health assessment, community health improvement planning, quality improvement, and use of the Community Guide were associated with lower levels of engagement in resource sharing. Doctoral degree of the top executive and having 1 or more local boards of health carried a positive influence on resource sharing. Cross-jurisdictional resource sharing is a viable and commonly used process to overcome the challenges of new and emerging public health problems within the constraints of restricted budgets. LHDs, particularly smaller LHDs with limited resources, should consider increased resource sharing to address emerging challenges.

    Full Text Available With the birth and growth of the arbitration phenomena in recent decades, establishment of Court of Arbitration in the form of International Commercial Arbitration Law, international treaties and domestic independent and particular laws by countries, the increasing tendency of traders and businesses to resolve problems through this body gradually leads to excellence of the position of this body and typically coercion and obligation of officials and supporters of this entity to modify or supplement the former rules or ratify new and progressive legislation with broader discretionary limits for arbitrators, so that the establishment and ratification of regulations in form of conventions with membership of many countries has been the result of meeting will of politicians with fortune and tendency of businessmen, merchants and etc. If there is alleged invalidity of the contract, Limits and scope of arbitration referee. This issue calls “competence-competence” principle and we seek to investigate whether the possibility of accepting the competence to judge. It means making decision about competence of referee. Competency of arbitration board is inherent and it is created by law and it is separate from competency of public arbitration. Arbitration ritual theory is differences as a separate method of dispute resolution in international commercial transactions. However, Consistent with the dominance of the national authority on private equity, the entity is located at the foot of the rights of nature into the public law; although, private perspective is dominance.

    The purpose of this study was to develop assessment criteria that could be used to examine the level of integration of home birth within larger health care systems in developed countries across 11 international jurisdictions. An expert panel developed criteria and a definition to assess home birth integration within health care systems. We selected jurisdictions based on the publications that were eligible for inclusion in our systematic review and meta-analysis on planned place of birth. We sent the authors of the included publications a questionnaire about home birth practitioners and practices in their respective health care system at the time of their studies. We searched published peer-reviewed, non-peer-reviewed, and gray literature, and the websites of professional bodies to document information about home birth integration in each jurisdiction based on our criteria. Where information was lacking, we contacted experts in the field from the relevant jurisdiction. Home birth is well integrated into the health care system in British Columbia (Canada), England, Iceland, the Netherlands, New Zealand, Ontario (Canada), and Washington State (USA). Home birth is less well integrated into the health care system in Australia, Japan, Norway, and Sweden. This paper is the first to propose criteria for the evaluation of home birth integration within larger maternity care systems. Application of these criteria across 11 international jurisdictions indicates differences in the recognition and training of home birth practitioners, in access to hospital facilities, and in the supplies and equipment available at home births, which give rise to variation in the level of integration across different settings. Standardized criteria for the evaluation of systems integration are essential for interpreting planned home birth outcomes that emerge from contextual differences. © 2018 Wiley Periodicals, Inc.

    2016-01-01

    Highlights: • We studied ZnO nanorods film for liquefied petroleum gas (LPG) sensing. • The Au sensitization on ZnO nanorods gives improved LPG sensing response. • The Au–ZnO shows 48% LPG response for 1040 ppm with fast response time of 50 S. • We proposed schematic for sensing mechanism using band diagram. - Abstract: The zinc oxide (ZnO) nanorods have grown on glass substrate by spray pyrolysis deposition (SPD) method using zinc acetate solution. The phase formation, surface morphology and elemental composition of ZnO films have been investigated using X-ray diffraction, field emission scanning electron microscopy (FE-SEM), atomic force microscopy (AFM) and energy dispersive X-ray (EDX) techniques. The liquefied petroleum gas (LPG) sensing response was remarkably improved by sensitization of gold (Au) surface noble metal on ZnO nanorods film. Maximum LPG response of 21% was observed for 1040 ppm of LPG, for pure ZnO nanorods sample. After Au sensitization on ZnO nanorods film sample, the LPG response greatly improved up to 48% at operating temperature 623 K. The improved LPG response is attributed Au sensitization with spill-over mechanism. Proposed model for LPG sensing mechanism discussed.

    2016-02-01

    Full Text Available In this study, activated carbon fibers (ACFs were prepared from liquefied wood by chemical activation with ZnCl2, with a particular focus on the effects of temperature and ZnCl2: liquefied wood-based fiber (LWF ratio on yield, porous texture, and surface chemistry. The characterization and properties of these ACFs were investigated by nitrogen adsorption/desorption, Fourier transform infrared (FTIR spectroscopy, and X-ray photoelectron spectroscopy (XPS. When using a 6:1 impregnation ratio, the specific surface area (SBET of the resultant ACFs was as high as 1423 m2/g. The effect of an increase in impregnation ratio on the porosity of ACFs was stronger than that of an increase in the activation temperature. However, the former had a weaker impact on the surface chemistry and structure. It was also found that the yields of ACFs obtained by ZnCl2 activation were higher than those obtained by physical activation. Besides, the prepared ACFs presented higher adsorption than other raw materials in the adsorption test, indicating that ACFs prepared from LWF by ZnCl2 activation could be used as an adsorbent for the adsorption of medium size organic compounds.

    Full Text Available Corn stover was successfully liquefied by microwave heating at 160 °C with ethylene glycol (EG used as the solvent and sulfuric acid as a catalyst. Gas chromatography and mass spectrometry (GC-MS data indicated that methyl esters, including 3-(2-methyl-1,3-doxolane-2-yl propionic acid methyl ester (PAME, levulinic acid isopropyl ester (LAE, methyl laurate, and methyl palmitate were the major degradation compounds, in addition to EG derivatives in the liquefied product of corn stover (LPCS. For high value-added utilization of LPCS, solvent extraction was applied to characterize the components and to separate it into useful fractions. After being dispersed in water, the water-soluble fraction of the LPCS was then extracted with organic solvents, including hexane, chloroform, diethyl ether, and ethyl acetate. Levulinic acid isopropyl ester showed the highest distribution in chloroform and ethyl acetate, while the lowest in hexane and ether. Levulinic acid isopropyl ester was selectively enriched to 28.76% and 43.65% by sequential extraction with chloroform and ethyl acetate, respectively, in accordance with the quantitative analysis.

  6. Shake table test of soil-pile groups-bridge structure interaction in liquefiable ground

    2010-03-01

    This paper describes a shake table test study on the seismic response of low-cap pile groups and a bridge structure in liquefiable ground. The soil profile, contained in a large-scale laminar shear box, consisted of a horizontally saturated sand layer overlaid with a silty clay layer, with the simulated low-cap pile groups embedded. The container was excited in three El Centro earthquake events of different levels. Test results indicate that excessive pore pressure (EPP) during slight shaking only slightly accumulated, and the accumulation mainly occurred during strong shaking. The EPP was gradually enhanced as the amplitude and duration of the input acceleration increased. The acceleration response of the sand was remarkably influenced by soil liquefaction. As soil liquefaction occurred, the peak sand displacement gradually lagged behind the input acceleration; meanwhile, the sand displacement exhibited an increasing effect on the bending moment of the pile, and acceleration responses of the pile and the sand layer gradually changed from decreasing to increasing in the vertical direction from the bottom to the top. A jump variation of the bending moment on the pile was observed near the soil interface in all three input earthquake events. It is thought that the shake table tests could provide the groundwork for further seismic performance studies of low-cap pile groups used in bridges located on liquefiable groun.

    Macroalgae are one of potential sources for carotenoids, such as fucoxanthin, which are consumed by humans and animals. This carotenoid has been applied in both the pharmaceutical and food industries. In this study, extraction of fucoxanthin from wet brown seaweed Undaria pinnatifida (water content was 93.2%) was carried out with a simple method using liquefied dimethyl ether (DME) as an extractant in semi-continuous flow-type system. The extraction temperature and absolute pressure were 25 °C and 0.59 MPa, respectively. The liquefied DME was passed through the extractor that filled by U. pinnatifida at different time intervals. The time of experiment was only 43 min. The amount of fucoxanthin could approach to 390 μg/g dry of wet U. pinnatifida when the amount of DME used was 286 g. Compared with ethanol Soxhlet and supercritical CO2 extraction, which includes drying and cell disruption, the result was quite high. Thus, DME extraction process appears to be a good method for fucoxanthin recovery from U. pinnatifida with improved yields. PMID:24796299

    Full Text Available Massimiliano Godani,1 Francesca Canavese,1 Sonia Migliorini,2 Massimo Del Sette1 1Neurology Unit, 2Department of Neuroradiology, Sant’Andrea Hospital, La Spezia, Italy Abstract: The practice of inhaling liquefied petroleum gas (LPG to commit suicide is uncommon and almost exclusively a prerogative of the prison population. Numerous cases of sudden deaths caused by intentional propane and/or butane inhalation have been described, but these cases survived and a description of the consequences is very rare. We describe a prisoner who survived after voluntary inhalation of LPG, and who developed ataxia, Parkinsonism, and dystonia. Brain MRI showed bilateral hyperintensity in the basal ganglia and in the cerebellar hemispheres. The clinical evolution and the MRI abnormalities are similar to those described in cases of poisoning by CO where the mechanism of brain injury is related to histotoxic hypoxia. We believe that LPG, considered until now a mixture of gas with low neurotoxic power, may have caused direct toxic damage to the brain, mediated by a mechanism of hypoxia, such as in CO intoxication. Keywords: ataxia, Parkinsonism, dystonia, liquefied petroleum gas

    Highlights: • We studied ZnO nanorods film for liquefied petroleum gas (LPG) sensing. • The Au sensitization on ZnO nanorods gives improved LPG sensing response. • The Au–ZnO shows 48% LPG response for 1040 ppm with fast response time of 50 S. • We proposed schematic for sensing mechanism using band diagram. - Abstract: The zinc oxide (ZnO) nanorods have grown on glass substrate by spray pyrolysis deposition (SPD) method using zinc acetate solution. The phase formation, surface morphology and elemental composition of ZnO films have been investigated using X-ray diffraction, field emission scanning electron microscopy (FE-SEM), atomic force microscopy (AFM) and energy dispersive X-ray (EDX) techniques. The liquefied petroleum gas (LPG) sensing response was remarkably improved by sensitization of gold (Au) surface noble metal on ZnO nanorods film. Maximum LPG response of 21% was observed for 1040 ppm of LPG, for pure ZnO nanorods sample. After Au sensitization on ZnO nanorods film sample, the LPG response greatly improved up to 48% at operating temperature 623 K. The improved LPG response is attributed Au sensitization with spill-over mechanism. Proposed model for LPG sensing mechanism discussed.

    Process Synthesis (PS) is a term used to describe a class of general and systematic methods for the conceptual design of processing plants and energy systems. The term also refers to the development of the process flowsheet (structure or topology), the selection of unit operations and the determination of the most important operating conditions.In this thesis an attempt is made to characterize some of the most common methodologies in a PS pyramid and discuss their advantages and disadvantages as well as where in the design phase they could be used most efficiently. The thesis shows how design tools have been developed for subambient processes by combining and expanding PS methods such as Heuristic Rules, sequential modular Process Simulations, Pinch Analysis, Exergy Analysis, Mathematical Programming using Deterministic Optimization methods and optimization using Stochastic Optimization methods. The most important contributions to the process design community are three new methodologies that include the pressure as an important variable in heat exchanger network synthesis (HENS).The methodologies have been used to develop a novel and efficient energy chain based on stranded natural gas including power production with carbon capture and sequestration (CCS). This Liquefied Energy Chain consists of an offshore process a combined gas carrier and an onshore process. This energy chain is capable of efficiently exploiting resources that cannot be utilized economically today with minor Co2 emissions. Finally, a new Stochastic Optimization approach based on a Tabu Search (TS), the Nelder Mead method or Downhill Simplex Method (NMDS) and the sequential process simulator HYSYS is used to search for better solutions for the Liquefied Energy Chain with respect to minimum cost or maximum profit.

  12. Precautionary principles: a jurisdiction-free framework for decision-making under risk.

    Science.gov (United States)

    Ricci, Paolo F; Cox, Louis A; MacDonald, Thomas R

    2004-12-01

    Fundamental principles of precaution are legal maxims that ask for preventive actions, perhaps as contingent interim measures while relevant information about causality and harm remains unavailable, to minimize the societal impact of potentially severe or irreversible outcomes. Such principles do not explain how to make choices or how to identify what is protective when incomplete and inconsistent scientific evidence of causation characterizes the potential hazards. Rather, they entrust lower jurisdictions, such as agencies or authorities, to make current decisions while recognizing that future information can contradict the scientific basis that supported the initial decision. After reviewing and synthesizing national and international legal aspects of precautionary principles, this paper addresses the key question: How can society manage potentially severe, irreversible or serious environmental outcomes when variability, uncertainty, and limited causal knowledge characterize their decision-making? A decision-analytic solution is outlined that focuses on risky decisions and accounts for prior states of information and scientific beliefs that can be updated as subsequent information becomes available. As a practical and established approach to causal reasoning and decision-making under risk, inherent to precautionary decision-making, these (Bayesian) methods help decision-makers and stakeholders because they formally account for probabilistic outcomes, new information, and are consistent and replicable. Rational choice of an action from among various alternatives--defined as a choice that makes preferred consequences more likely--requires accounting for costs, benefits and the change in risks associated with each candidate action. Decisions under any form of the precautionary principle reviewed must account for the contingent nature of scientific information, creating a link to the decision-analytic principle of expected value of information (VOI), to show the

    Full Text Available Introduction. Biologically active substances (BAS of barberry roots represented by alkaloids of isoquinoline group are perspective substances for development of preparations with multiple pharmacological activities. However, now manufacture of them in Ukraine is stopped. One of the reasons of this is out-of-date production technologies of alkaloids involving use of toxic and/or flammable solvents. In the article possibility for application of liquefied gases in technology of obtaining of alkaloids from barberry roots has been studied. Materials and methods. Initial raw herb drug were barberry (Berberis vulgaris roots harvested in spring on the territory of Southern Ukraine. Their moisture content was 11%, comminuting degree was 0,5-1,4 mm. At the first stage purification of raw herb drug from lipophilic impurities (defatting was made with use of some liquefied gases: tetrafluoroethane, isobutane, difluorochloromethane and difluoromethane. Extraction of the alkaloid sum was made with difluoromethane mixed with various quantities of liquid ammonia or diethylamine as alkaline agent. Crude extracts were exposed to two-level liquefied-gas purification. At first the alkaloid bases were transformed into saline forms with aqueous solutions of acids and purified from ballast impurities with liquefied freon-22. Then alkaloid salts were reextracted from aqueous phase in the base form with liquefied mixture of difluoromethane and ammonia. Mixing of liquid phases was provided by creation of alternate gradients of temperatures and, as consequence, pressures between separators feeding alternately cool water into jacket of one of them, and warm water – into jacket of another one. Quantity of lipophilic ballast impurities and also weight of extractives were determined gravimetrically. Quantitative analysis of the alkaloid sum was made by titrimetric method after sedimentation of alkaloids with volumetric solution of phosphomolybdic acid. Results and discussion

They recorded their discomfort on visual analog scales immediately after separator placement, 2 hours later, 6 hours later, at bedtime, and 24 hours after separator placement. Repeated measure analysis of variance (ANOVA was used to compare the mean pain scores between the three groups. Data were collected from 89 patients. The pain increased with time in all groups. Pain scores were statistically lower in the analgesic groups compared with the placebo group (P.value<0.001, but no statistically significant difference was found in mean pain scores between the two drug groups (acetaminophen and liquefied ibuprofen (P.value=1. Acetaminophen and liquefied ibuprofen have similar potential in pain reduction during separation.

  15. The Determination of Jurisdiction in Grid and Cloud Service Level Agreements

    Science.gov (United States)

    Parrilli, Davide Maria

    Service Level Agreements in Grid and Cloud scenarios can be a source of disputes particularly in case of breach of the obligations arising under them. It is then important to determine where parties can litigate in relation with such agreements. The paper deals with this question in the peculiar context of the European Union, and so taking into consideration Regulation 44/2001. According to the rules on jurisdiction provided by the Regulation, two general distinctions are drawn in order to determine which (European) courts are competent to adjudicate disputes arising out of a Service Level Agreement. The former is between B2B and B2C transactions, and the latter regards contracts which provide a jurisdiction clause and contracts which do not.

    2013-01-01

    This review compares the regulations, definitions and approval processes for substances intentionally added to or unintentionally present in human food in the following specific countries/jurisdictions: Argentina, Australia, Brazil, Canada, China, the European Union, Japan, Mexico, New Zealand, and the United States. This includes direct food additives, food ingredients, flavouring agents, food enzymes and/or processing aids, food contact materials, novel foods, and nanoscale materials for food applications. The regulatory authority of each target jurisdiction/country uses its own regulatory framework and although the definitions, regulations and approval processes may vary among all target countries, in general there are many similarities. In all cases, the main purpose of each authority is to establish a regulatory framework and maintain/enforce regulations to ensure that food consumed and sold within its respective countries is safe. There is a move towards harmonisation of food regulations, as illustrated by Australia and New Zealand and by Mercosur. The European Union has also established regulations, which are applicable for all member states, to establish a common authorisation procedure for direct food additives, flavourings and enzymes. Although the path for approval of different categories of food additives varies from jurisdiction to jurisdiction, there are many commonalities in terms of the data requirements and considerations for assessment of the safety of use of food additives, including the use of positive lists of approved substances, pre-market approval, and a separation between science and policy decisions. The principles applied are largely reflective of the early work by the Joint FAO/WHO Expert Committee on Food Additives (JECFA) committees and JECFA assessments of the safety of food additives for human and animal foods.

  17. Fuel Mix Impacts from Transportation Fuel Carbon Intensity Standards in Multiple Jurisdictions

    Science.gov (United States)

    Witcover, J.

    2017-12-01

    Fuel carbon intensity standards have emerged as an important policy in jurisdictions looking to target transportation greenhouse gas (GHG) emissions for reduction. A carbon intensity standard rates transportation fuels based on analysis of lifecycle GHG emissions, and uses a system of deficits and tradable, bankable credits to reward increased use of fuels with lower carbon intensity ratings while disincentivizing use of fuels with higher carbon intensity ratings such as conventional fossil fuels. Jurisdictions with carbon intensity standards now in effect include California, Oregon, and British Columbia, all requiring 10% reductions in carbon intensity of the transport fuel pool over a 10-year period. The states and province have committed to grow demand for low carbon fuels in the region as part of collaboration on climate change policies. Canada is developing a carbon intensity standard with broader coverage, for fuels used in transport, industry, and buildings. This study shows a changing fuel mix in affected jurisdictions under the policy in terms of shifting contribution of transportation energy from alternative fuels and trends in shares of particular fuel pathways. It contrasts program designs across the jurisdictions with the policy, highlights the opportunities and challenges these pose for the alternative fuel market, and discusses the impact of having multiple policies alongside federal renewable fuel standards and sometimes local carbon pricing regimes. The results show how the market has responded thus far to a policy that incentivizes carbon saving anywhere along the supply chain at lowest cost, in ways that diverged from a priori policy expectations. Lessons for the policies moving forward are discussed.

    Liquefied petroleum gas (LPG) sensing properties of ZnO thin films consisting of sub-micron rods synthesized by chemical bath deposition (CBD) method are presented in depth. The scanning electron microscopy observation reveals that ZnO sub-micron rods are of hexagonal in phase grown perpendicular to the substrate surface. Due to large surface area, the ZnO thin films of sub-micron rods were sensitive to the explosive LPG, which was studied for different time depositions and for different operating temperatures. The maximum response of 28% at 673 K was recorded under the exposure of 10% of lower explosive level (LEL) of LPG. The ZnO thin films of sub-micron rods exhibited good sensitivity and rapid response-recovery characteristics towards LPG

    Underground pipelines are widely applied in the so-called lifeline engineerings. It shows according to seismic surveys that the damage from soil liquefaction to underground pipelines was the most serious, whose failures were mainly in the form of pipeline uplifting. In the present study, dynamic centrifuge model tests were conducted to study the uplifting behaviors of shallow-buried pipeline subjected to seismic vibration in liquefied sites. The uplifting mechanism was discussed through the responses of the pore water pressure and earth pressure around the pipeline. Additionally, the analysis of force, which the pipeline was subjected to before and during vibration, was introduced and proved to be reasonable by the comparison of the measured and the calculated results. The uplifting behavior of pipe is the combination effects of multiple forces, and is highly dependent on the excess pore pressure.

    Analysis of seismic response of structures located at a site with potential for soil liquefaction has drawn attention of many researchers. The topic is particularly important in the design of critical facilities like nuclear reactors and defense installations. This paper presents the results of a study involving evaluation of coupled seismic response of structures (model nuclear reactors) and characteristics of soil liquefaction at a site. The analysis procedure employed is based on the nonlinear finite element (FE) technique and accounts for the interaction effects due to a neighboring structure. Emphasis is given to the following features: prediction of spatial and temporal variation of pore water pressure; identification of the on-set of liquefaction based on the effective stress approach, and tracing the propagation of the liquefied zones with time and resulting response of the structures

    Fire impingement on vessels containing pressure liquefied gases can result in catastrophic failure of the vessel leading to a Boiling Liquid Expanding Vapour Explosion (BLEVE). If the gas is flammable, this can result in the formation of very large fireballs. In safety assessments where catastrophic vessel failure is identified as a real possibility, the risk of death from a fireball tends to be higher than that from missiles or blast. Since many of the physical processes which take place in a BLEVE are scale dependent, a series of tests were undertaken at a large scale where 2 tonne propane vessels were taken to failure in a jet fire and the vessel response, mode of failure and consequence of failure characterised. The measurements taken by the Health and Safety Laboratory and BG Technology relating to fireball formation are described. (Author)

    2018-01-01

    Full Text Available The throttling of liquefied substances from high pressure vessels to an enclosed volume starting at atmospheric pressure is described in order to determine thermodynamic state of the extinguished room gaseous contents. Time dependent, 0D mathematical model is implemented describing the state inside the agent container, the isenthalpic throttling in the distribution system, agent vaporization and mixing with air. The agent is modelled as real gas. Other influences on the process including the heat transfer from selected solid parts inside the room and the gas mixture leakage out of the room are taken into account. Main outcome is an MS Excel tool for integrated fire extinguishers design optimization. The optimization balances the two contradictory requirements: Agent volumetric concentration to sustain the fire extinguishing capabilities and tolerable room overpressure. Agent fill weight and discharge time are being adjusted. The discharge time is controlled by the distribution piping and spray nozzles design. System operation is checked concerning various initial and boundary conditions.

    Anemia can be an indicator of poor nutrition and health, and it can have significant consequences. Children are disproportionately affected by anemia. This comprehensive review summarizes the available literature on anemia prevalence in young children in the islands of the Oceania region. The anemia prevalence, the criteria used for diagnosis, the date the data was reported, and the types of samples collected were reviewed. Anemia prevalence estimates were reported for eighteen of the Pacific Island Jurisdictions. From the fifteen data sources that were evaluable, anemia prevalence ranged from 12.3% to over 70%. A major limitation in the data is a lack of representative primary data from many of the jurisdictions in the region. Prevalance estimates reported for those jurisdictions are estimated by regression analysis from the World Health Organization (WHO). Moreover, the primary data available does not use standardized reporting criteria. Nevertheless, this review serves as a new baseline for further investigations on the prevalence of anemia and a baseline for evaluating public health prevention and treatment measures to detect and improve anemia prevalence in the Pacific.

  14. JURISDICTION OVER CRIMES COMMITTED ON BOARD AIRCRAFT IN FLIGHT UNDER THE TOKYO CONVENTION 1963

    Full Text Available Purpose: the main aim of this paper is to clarify several issues of conflicting jurisdiction over crimes committed on board aircraft in flight. The study will examine the way in which the Tokyo Convention attempts to provide justice in the event of aviation security violations, and discuss its effectiveness in preventing such offences in the future. Methods: formal legal and case-study methods together with inductive reasoning, and comparison were used to analyse the legislation in the area of jurisdiction over crimes and other offences committed on board aircraft in flight. Results: it follows from the study that although the Tokyo Convention has contributed considerably to the establishing of clearer rules of jurisdiction over offences committed on board aircraft, considerable deficiencies of this treaty remain. The results have important implications for international policy-making. Discussion: the results of the study reveal several weaknesses of the Tokyo Convention. Firstly, it does not provide any definition or list of offences to which it applies, instead it relies on national penal laws to do so. In addition, the ‘freedom fighter exception’ and the lack of a strong enforcement mechanism may prove to impede the effective attainment of the Tokyo Convention’s main objectives – that is, to provide justice in the event of aviation security violations, and prevent such offences in the future. Therefore, further improvement in aviation security legislation is necessary to ensure that it is effective and adequate in the challenges faced today.

    2010-01-01

    Spurred by a desire to improve quality of care and to understand the relative value of medical treatments, there has been a recent surge of interest in publicly funded comparative effectiveness research (CER) in the US. As health technology assessment (HTA) shares some of the same goals as CER, and publicly funded HTA has been a feature within other industrialized countries for many years, a review of HTA activities in some of these countries can be a helpful source of information for the US debate. Informed by a literature review, and in two cases augmented by informant interviews, we reviewed the organization of HTA activities in five jurisdictions: Canada, Sweden, Scotland, the Netherlands and Australia. We provide a summary description of the healthcare system in each country as well as a description of the key features of their HTA bodies, with a particular focus on the processes of HTA for listing medications on public formularies. Four of the committees evaluating medications for formulary inclusion are funded by, but remain at arm's length from, the government (Canada, Australia, Sweden and Scotland), while the process is fully embedded within the government in the Netherlands. Each of these jurisdictions has a stated preference for comparative outcomes evidence from randomized controlled trials, but will, under certain circumstances, accept randomized evidence using surrogate markers, other comparators that are not directly relevant or non-randomized evidence. Health technology evaluation committees largely comprise health professionals, with public representatives included in the Canadian, Australian and Scottish committees. Scotland is the only one of the five jurisdictions reviewed to have industry representation on the evaluation committee. We identified seven characteristics that are shared across the jurisdictions reviewed and that potentially serve as insights for development of CER in the US: (i) the process must be responsive to stakeholders

  1. The problem of epistemic jurisdiction in global governance: The case of sustainability standards for biofuels.

    2017-02-01

    While there is ample scholarly work on regulatory science within the state, or single-sited global institutions, there is less on its operation within complex modes of global governance that are decentered, overlapping, multi-sectorial and multi-leveled. Using a co-productionist framework, this study identifies 'epistemic jurisdiction' - the power to produce or warrant technical knowledge for a given political community, topical arena or geographical territory - as a central problem for regulatory science in complex governance. We explore these dynamics in the arena of global sustainability standards for biofuels. We select three institutional fora as sites of inquiry: the European Union's Renewable Energy Directive, the Roundtable on Sustainable Biomaterials, and the International Organization for Standardization. These cases allow us to analyze how the co-production of sustainability science responds to problems of epistemic jurisdiction in the global regulatory order. First, different problems of epistemic jurisdiction beset different standard-setting bodies, and these problems shape both the content of regulatory science and the procedures designed to make it authoritative. Second, in order to produce global regulatory science, technical bodies must manage an array of conflicting imperatives - including scientific virtue, due process and the need to recruit adoptees to perpetuate the standard. At different levels of governance, standard drafters struggle to balance loyalties to country, to company or constituency and to the larger project of internationalization. Confronted with these sometimes conflicting pressures, actors across the standards system quite self-consciously maneuver to build or retain authority for their forum through a combination of scientific adjustment and political negotiation. Third, the evidentiary demands of regulatory science in global administrative spaces are deeply affected by 1) a market for standards, in which firms and states can

    The Department of Health and Human Services recommends drug resistance testing at linkage to HIV care. Because receipt and timing of testing are not well characterized, we examined testing patterns among persons with diagnosed HIV who are linked to care. Using surveillance data in six jurisdictions for persons aged ≥13 years with HIV infection diagnosed in 2013, we assessed the proportion receiving testing, and among these, the proportion receiving testing at linkage. Multivariable log-binomial regression modeling estimated associations between selected characteristics and receipt of testing (1) overall, and (2) at linkage among those tested. Of 9,408 persons linked to care, 66% received resistance testing, among whom 68% received testing at linkage. Less testing was observed among male persons who inject drugs (PWID), compared with men who have sex with men (adjusted prevalence ratio [aPR]: 0.88; 95% confidence interval [CI]: 0.81-0.97) and persons living in areas with population testing was lower for persons with initial CD4 counts ≥500 cells/mm 3 , compared with those with CD4 counts tested, testing at linkage was lower among male PWID (aPR: 0.85; CI: 0.75-0.95) and, in some jurisdictions, persons with CD4 counts ≥500 cells/mm 3 (aPR range: 0.63-0.73). Two-thirds of persons with diagnosed HIV who were linked to care received resistance testing, and most received testing at linkage as recommended. Improving receipt and timing of testing among male PWID, persons in less populous settings, and in all jurisdictions, regardless of CD4 count, may improve care outcomes.

    The jurisdiction in modern environmental penal law has gone beyond just adopting the ecological tenets of the legislature: it has farthered their development, thus contributing substantially to an ecologically oriented understanding of the offences of water pollution and ecologically harmful waste disposal. This orientation has made prosecution more efficient and through its preventive effects has increased ecological awareness. A good example within the sphere of public interest are communal plant operators. In other areas such as private business and private households the preventive effect is not yet as apparent, but this will probably change in the course of time. (orig.) [de

    There is risk of bridge foundations to be damaged by liquefaction-induced lateral spreading of ground. Once bridge foundations have been damaged, it takes a lot of time for restoration. Therefore, it is important to assess the seismic behavior of the foundations on liquefiable ground appropriately. In this study, shaking table tests of models on a scale of 1/10 were conducted at the large scale shaking table in Public Works Research Institute, Japan, to investigate the seismic behavior of pile-supported bridge abutment on liquefiable ground. The shaking table tests were conducted for three types of model. Two are models of existing bridge which was built without design for liquefaction and the other is a model of bridge which was designed based on the current Japanese design specifications for highway bridges. As a result, the bending strains of piles of the abutment which were designed based on the current design specifications were less than those of the existing bridge.

    This paper discussed a coupled stress-flow dynamic analysis procedure designed to predict the stability and seismic deformations of an 85 meter high earth dam located near a polymetallic mine in Vietnam. The procedure was developed to capture sand element behaviours observed in previous laboratory tests. The analysis was conducted using a UBCSAND model to capture the liquefiable soil response. Nonlinear behaviour of the non-liquefiable materials was modelled using the UBCHYST simulation tool. Both models were incorporated within the FLAC model. Dam specifications, foundation characteristics, and predicted behaviours were discussed. The dam body and its foundation were analyzed under gravity loads with drained conditions in order to establish the pre-earthquake stress state. A dynamic analysis was then conducted using undrained properties for fine-grained soils. The FLAC model finite difference analysis was used to examine stress-flow under static and dynamic loading conditions. Earthquake motions were applied as a time history of excitation at the model's boundaries. Volumetric strains were controlled by the compressibility of the pore fluid and the flow of water through the soil elements. The model was calibrated using laboratory and centrifuge data. Results of the study showed that the tailings and downstream free-field alluvial soils developed high excess pore water pressures and liquefied during strong shaking motions. Results suggested that the seismic performance of the Oxide dam were satisfactory. 41 refs., 1 tab., 7 figs.

    This paper describes the summary of the research achievements in fiscal 1990 in developing coal liquefying technologies. The bituminous coal liquefaction project is scheduled to have a 150-t/d pilot plant start operation from the latter half of fiscal 1994. Research problems were reviewed based on the basic and detailed designs. Construction processes were also reviewed by each facility. Detailed design was performed on the main four facilities for pretreatment, liquefying reaction, liquefied oil distillation, and solvent hydrogenation. Support researches were carried out on the pilot plant in addition to 1-t/d PSU and small testing devices. In the research of a brown coal liquefying technology, operation of the pilot plant (50 t/d) was resumed after completion of the long-term operation (Run 7) having been executed in fiscal 1989, and after the extraordinary repair. The planned operation has been completed as scheduled. Modification and repair works were also carried out. Researches were made on upgrading of brown coal liquefied oil, and a petroleum mixing technology. The paper also describes the support researches. In developing the common basic technologies, studies were performed on development of plant devices, investigation on coal type selection, applications of coal liquefied products, and a refining technology. An environment preserving technology was also developed. The development made it possible to identify the whole image relative to the relevant laws and regulations on the comprehensive operation oil in the whole fraction and by fractions. Comprehensive management of the research and development was also implemented. (NEDO)

    In this paper, {{{Mn}}}2{{{O}}}3 and {{{ZnMn}}}2{{{O}}}4 nanoparticles (NPs) are successfully synthesized using chemical co-precipitation method at room temperature and further annealed at 450 °C. The structure, crystallite size, morphology, specific surface area (SSA) and band gap energy have been determined by x-ray diffraction, transmission electron microscopy, Brunauer-Emmett-Teller surface area analysis, scanning electron microscopy (SEM-EDS) and UV-visible spectrophotometer. The sensor films of the {{{Mn}}}2{{{O}}}3 NPs and {{{ZnMn}}}2{{{O}}}4 NPs have been fabricated onto glass substrate using spin coater system separately. These sensor films are investigated for different concentrations (200-1200 ppm) of liquefied petroleum gas (LPG) at different operating temperatures ranging from 100 °C to 400 °C. A comparative study of gas sensing properties shows that spinel {{{ZnMn}}}2{{{O}}}4 sensor film exhibit excellent response (≈ 80 % ) towards 1000 ppm LPG at 300 °C in comparison to {{{Mn}}}2{{{O}}}3 sensor films. The enhancement in the gas sensing characteristics of {{{ZnMn}}}2{{{O}}}4 sensor film is attributed to the reduced crystallite size, greater SSA, and modification in structure as well as morphology.

    Development of highly sensitive and selective semiconductor-based metal oxide sensor devices to detect toxic, explosive, flammable, and pollutant gases is still a challenging research topic. In the present work, we systematically enhanced the liquefied petroleum gas (LPG) sensing performance of chemical bath deposited TiO 2 nanorods by decorating Pd nanoparticle catalyst. Surface morphology with elemental mapping, crystal structure, composition and oxidation states, and surface area measurements of pristine TiO 2 and Pd:TiO 2 nanorods was examined by high resolution transmission electron microscopy with energy-dispersive X-ray spectroscopy, X-ray diffraction, X-ray photoelectron spectroscopy, and nitrogen adsorption-desorption characterization techniques. LPG sensing performance of pristine TiO 2 and Pd:TiO 2 nanorods was investigated in different LPG concentration and operating temperature ranges. The LPG response of 21% for pristine TiO 2 nanorods is enhanced to 49% after Pd catalyst decoration with reasonably fast response and recovery times. Further, the sensor exhibited long-term stability, which could be due to the strong metal support (Pd:TiO 2 ) interaction and catalytic properties offered by the Pd nanoparticle catalyst. The work described herein demonstrates a general and scalable approach that provides a promising route for rational design of variety of sensor devices for LPG detection.

    We introduce polyaniline-cadmium ferrite (PANI-CdFe2O4) nanostructured composite as a room-temperature-operable liquefied petroleum gas (LPG) sensor. The structure of PANI and the composite prepared by chemical polymerization was characterized by Fourier-transform infrared (FT-IR) spectroscopy, x-ray diffraction (XRD) analysis, and field-emission scanning electron microscopy. Comparative XRD and FT-IR analysis confirmed CdFe2O4 embedded in PANI matrix with mutual interfacial interaction. The nanostructure of the composite was confirmed by transmission electron microscopy. A simple LPG sensor operable at room temperature, exclusively based on spin-coated PANI-CdFe2O4 nanocomposite, was fabricated with maximum sensing response of 50.83% at 1000 ppm LPG. The response and recovery time of the sensor were 50 s and 110 s, respectively, and it was stable over a period of 1 month with slight degradation of 4%. The sensing mechanism is discussed on the basis of the p- n heterojunction barrier formed at the interface of PANI and CdFe2O4.

    In the present study, reduction of Titania (TiO2) by liquefied petroleum gas (LPG)-hydrogen-argon gas mixture was investigated by experimental and kinetic modelling in MATLAB. The reduction experiments were carried out in the temperature range of 1100-1200°C with a reduction time from 1-3 hours and 10-20 minutes of LPG flowing time. A shrinking core model (SCM) was employed for the kinetic modelling in order to determine the rate and extent of reduction. The highest experimental extent of reduction of 38% occurred at a temperature of 1200°C with 3 hours reduction time and 20 minutes of LPG flowing time. The SCM gave a predicted extent of reduction of 82.1% due to assumptions made in the model. The deviation between SCM and experimental data was attributed to porosity, thermodynamic properties and minute thermal fluctuations within the sample. In general, the reduction rates increased with increasing reduction temperature and LPG flowing time.

    In this study, the first and second laws of thermodynamics are used to analyze the quantity and quality of energy in a small compact trigeneration system. This combined cycle is composed of a little reciprocating ICE model GM, 1.0 CORSA (internal combustion engine), using LPG (liquefied petroleum gas) as fuel, HE1 and HE2 (two heat exchangers) and an AM (absorption machine) using ammonia–water as working fluid mixture. The mass and energy balance equations of the engine and subsystems are reviewed in detail. Exergy of each involved stream is calculated and the exergetic balance of each subsystem is presented, as well as the global system, identifying where and why losses and irreversibilities occurs. Efficiencies based on the second law of thermodynamics are calculated for each subsystem and compared. Special attention is given to identification and quantification of second law efficiencies and the irreversibilities of various processes and subsystems. The determination of the irreversibilities in each subsystem is particularly important since they are not identified in traditional first law analysis. Furthermore, this study revealed that the combustion was the most important contributor to the system inefficiency representing 36.0% of the total exergy input and 73% of the total exergy destruction. The exergetic efficiency of the trigeneration system is determined to be 51.19%. - Highlights: • The energetic and exergetic performance of trigeneration system was studied. • The engine is the main exergetic destruction equipment. • The exergetic efficiency of the trigeneration system was 51.19%.

    Manual cigarette lighter refilling with butane/propane admixed liquefied petroleum gas (LPG) is a common low-income occupation in India. This practice may cause adverse health effects from LPG exposure among such workers. To assess respiratory status among LPG-exposed workers and non-exposed controls. We quantified the exposure and evaluated respiratory symptoms and lung function among 113 LPG refilling workers (aged 41.9±9.9 years) and 79 controls (aged 40.8±7.2 years). We used multiple linear regression analysis to estimate the LPG exposure response within the group of refilling workers, adjusting for age, height and smoking status. Compared to the controls, the LPG-exposed lighter refillers manifested a 190 ml decrement in 1-second forced expiratory volume (FEV1) (2.55±0.4 vs. 2.26±0.3 l) and a 6% decrement in FEV1/forced vital capacity (FVC) (both P decrements. This adverse effect may be relevant to other occupational groups heavily exposed to volatile hydrocarbons, especially those in marginal employment sectors.

    Full Text Available Soil stabilization has been widely used as an alternative to substitute the lack of suitable material on site. The use of nontraditional chemical stabilizers in soil improvement is growing daily. In this study a laboratory experiment was conducted to evaluate the effects of waterborne polymer on unconfined compression strength and to study the effect of cement grout on pre-venting of liquefiable sandy soils. The laboratory tests were performed including grain size of sandy soil, unit weight, ultrasonic pulse velocity, and unconfined compressive strength test. The sand and various amounts of polymer (1%, 2%, 3%, and 4% and cement (10%, 20%, 30%, and 40% were mixed with all of them into dough using mechanical kneader in laboratory conditions. Grouting experiment is performed with a cylindrical mould of  mm. The samples were subjected to unconfined compression tests to determine their strength after 7 and 14 days of curing. The results of the tests indicated that the waterborne polymer significantly improved the unconfined compression strength of sandy soils which have susceptibility of liquefaction.

    It is known that higher heat exchanger area, more number of expanders with higher efficiency and more involved configuration with multi-pressure compression system increase the plant efficiency of a helium liquefier. However, they involve higher capital investment and larger size. Using simulation software Aspen Hysys v 7.0 and exergy analysis as the tool of analysis, authors have attempted to identify various trade-offs while selecting the number of stages, the pressure levels in compressor, the cold-end configuration, the heat exchanger surface area, the maximum allowable pressure drop in heat exchangers, the efficiency of expanders, the parallel/series connection of expanders etc. Use of more efficient cold ends reduces the number of refrigeration stages and the size of the plant. For achieving reliability along with performance, a configuration with a combination of expander and Joule-Thomson valve is found to be a better choice for cold end. Use of multi-pressure system is relevant only when the number of refrigeration stages is more than 5. Arrangement of expanders in series reduces the number of expanders as well as the heat exchanger size with slight expense of plant efficiency. Superior heat exchanger (having less pressure drop per unit heat transfer area) results in only 5% increase of plant performance even when it has 100% higher heat exchanger surface area.

    Full Text Available The development of new energy sources has become particularly important from the perspective of energy security and environmental protection. Therefore, the utilization of waste resources such as industrial food wastes (IFWs in energy production is expected. The central research institute of electric power industry (CRIEPI, Tokyo, Japan has recently developed an energy-saving oil-extraction technique involving the use of liquefied dimethyl ether (DME, which is an environmentally friendly solvent. In this study, three common IFWs (spent coffee grounds, soybean, and rapeseed cakes were evaluated with respect to oil yield for biodiesel fuel (BDF production by the DME extraction method. The coffee grounds were found to contain 16.8% bio-oil, whereas the soybean and rapeseed cakes contained only approximately 0.97% and 2.6% bio-oil, respectively. The recovered oils were qualitatively analysed by gas chromatography-mass spectrometry. The properties of fatty acid methyl esters derived from coffee oil, such as kinematic viscosity, pour point, and higher heating value (HHV, were also determined. Coffee grounds had the highest oil content and could be used as biofuel. In addition, the robust oil extraction capability of DME indicates that it may be a favourable alternative to conventional oil extraction solvents.

    The use of 'Bobtail' trucks (6 and 9 ton) for distribution of Liquefied Petroleum Gas (LPG) in Brazilian cities represents a new and mobile source of risk. In this paper, it will be presented a discussion about some of the possible accident scenarios that can occur with this kind of vehicle, with emphasis on the possible consequences (BLEVE/fireball). The goal is to spread information and call attention of Government Authorities and gas distribution companies, as well as the general public, about this source of risk. In the case of a 9 ton fireball, fatalities could be expected up to 176 m, according to TNO models. Collapse of the tank engulfed in fire is expected in 10 to 20 minutes, a too short time interval for the arrival of a fire brigade and control of the situation. Suggestions are presented for the use of insulating coating in the tanks capable of withstanding an external fire for two hours without collapsing and the realization of a risk study for estimation of the impact of the use of insulation in terms of risk reduction for the population and a comparison of risks associated to the two forms of LPG distribution.

    An automatic ID identification system for gas cylinders' online production was developed based on the production conditions and requirements of the Technical Committee for Standardization of Gas Cylinders. A cylinder ID image acquisition system was designed to improve the image contrast of ID regions on gas cylinders against the background. Then the ID digits region was located by the CNN template matching algorithm. Following that, an adaptive threshold method based on the analysis of local average grey value and standard deviation was proposed to overcome defects of non-uniform background in the segmentation results. To improve the single digit identification accuracy, two BP neural networks were trained respectively for the identification of all digits and the easily confusable digits. If the single digit was classified as one of confusable digits by the former BP neural network, it was further tested by the later one, and the later result was taken as the final identification result of this single digit. At last, the majority voting was adopted to decide the final identification result for the 6-digit cylinder ID. The developed system was installed on a production line of a liquefied-petroleum-gas cylinder plant and worked in parallel with the existing weighing step on the line. Through the field test, the correct identification rate for single ID digit was 94.73%, and none of the tested 2000 cylinder ID was misclassified through the majority voting.

  1. Regulation and market power in the Spanish liquefied petroleum gas industry: Progress or failure?

    This paper presents a detailed study of the structure, market power and competition in the distribution sector for liquefied petroleum gas (LPG), within Spain. It is a segment of energy consumption and supply that is not often given serious attention, despite the fact that LPG is a crucial source of energy to many households, in many countries in Europe and in the rest of the world. Despite formally being an open and liberalized sector, the Spanish LPG market is characterized by high concentration within the industry; Repsol Butano, the dominant operator, practically controls the entire value chain. These structural characteristics probably justify state intervention in the form of price fixing, in order to guarantee accessible prices for final consumers. Nevertheless, applying this tool has had negative effects on the opening and liberalization process. On the one hand, it fails to encourage entry or an increase in the participation of new operators; on the other, it has considerably deteriorated the economic and financial performance of the distribution agents that are subjected to two strong forces. First, the dominant operator looks after its own interests and its income; and second, the Government tries to defend the interests of final consumers by fixing prices that inadequately remunerate the activity. This shows the contradictory regulatory actions that try to promote competition, and then establish mechanisms to regulate activity by fixing prices that act as price limits. These government set prices discourage new competitors from entering. (author)

  2. Study of Ground Treatment on Improvement of Pile Foundation Response in Liquefiable Soils

    Full Text Available In light of the disastrous the 2011 Tohoku Pacific Earthquake, the government of Japan has conducted studies to revise the seismic design code, and elevated peak ground accelerations have been adopted. Consequently, revisions on existing design to comply with the updated code are required for public projects that are still undergoing. The design safety needs to be reassessed, and implementation of strengthening measures is required if deemed necessary. For liquefaction countermeasures, ground treatment techniques that could increase the density of soils are often the preferable alternatives. The treatment usually increases the in-situ SPT-N or CPT-qc values, which in turn would increase the resistance of soil against liquefaction. For many public infrastructures in Japan supported by bored piles embedded partly or entirely in sandy soils, reevaluation of design safety against soil liquefaction would be required. In an assessment of possible retrofitting countermeasures for an infrastructure foundation, ground treatment has been considered. In this case study, effect of ground treatment on response of piles in liquefiable soils was investigated with numerical analyses using FLAC. Results provide insights into this ground treatment effect and useful information for consideration in future design or decision making.

    LPG (Liquefied Petroleum Gas). LPG is a hydrocarbon gas production from refineries and gas refinery with the major components of propane gas (C3H8) and butane (C4H10). Limit flame (Flammable Range) or also called gas with air. Value Lower Explosive Limit (LEL) is the minimum limit of the concentration of fuel vapor in the air which if there is no source of fire, the gas will be burned. While the value of the Upper Explosive Limit (UEL), which limits the maximum concentration of fuel vapor in the air, which if no source of fire, the gas will be burned. Protection system is a defend mechanism of human, equipment, and buildings around the protected area. Goals to be achieved in this research are to design a protection system against the consequences caused by the leakage of LPG gas based on ATmega16 microcontroller. The method used in this research is to reduce the levels of leaked LPG and turned off the power source when the leakage of LPG is on the verge of explosive limit. The design of this protection system works accurately between 200 ppm up to 10000 ppm, which is still below the threshold of explosive. Thus protecting the early result of that will result in the leakage of LPG gas.

  7. Stillbirth and the law: options for law reform and issues for the coronial jurisdiction.

    Freckelton, Ian

    2013-09-01

    In spite of its relative frequency, stillbirth is a phenomenon that has been relatively little discussed and requires further research for comprehensive clinical understanding. It impacts upon the legal system by way of the need to determine whether a life has come into being such that legal consequences such as criminal law, probate law and the coronial jurisdiction can attach to it. This requires contemporary clinically informed interpretation and application of the ancient "born alive rule" in respect of the ramifications of matters such as pulseless electrical activity in the heart, brain activity and agonal gasping. In the coronial domain, arguments have been put in South Australia, Victoria and Northern Ireland in recent cases and discussion has taken place publicly about whether coroners should be permitted to investigate and make findings and recommendations about cases of stillbirth. The article identifies merit in principle in such a development but highlights the need for care about such reform to the law lest it engender inconsistency in respect of important threshold definitions of "life" and "death" lest it generate incoherent approaches of the law on the subject, and lest it have unforeseen counter-therapeutic consequences for the grieving parents of infants who have been stillborn. It notes, too, that such a change to the ambit of coronial jurisdiction would have important resourcing ramifications.

  8. Why jurisdiction and uranium deposit type are essential considerations for exploration and mining of uranium

    International Nuclear Information System (INIS)

    Miller, D.

    2014-01-01

    Uranium is a relatively abundant element, being 25 times more common than silver, and having the same crustal abundance as tin. Economically minable uranium grades vary greatly, from a low of 0.01% U to over 20% U. What are the factors that allow mining of these very low grade ores that are only 50 times background concentrations? Why don’t the high grade deposits of the world exclusively supply all of the worlds newly mined uranium needs? There are two main reasons that the high grade deposits of the world do not exclusively supply all of the worlds newly mined uranium needs: 1) jurisdictional issues, the favorability or lack thereof of governmental policies where the deposit is located and the delays caused by an ineffective or corrupt policy and 2) the deposit type, which has a great influence on the recovery cost of the uranium. The quality of a deposit can override more difficult political jurisdictions if recovery of the investment occurs quickly and in an environmentally friendly way.

  9. Inconvenient marriages, or what happens when ethnic minorities marry trans-jurisdictionally

    Directory of Open Access Journals (Sweden)

    2010-06-01

    Full Text Available This article presents evidence of a trend in the practice of British immigration control of denying recognition to marriages which take place trans-jurisdictionally across national and continental boundaries and across different state jurisdictions. The article partly draws on evidence gleaned from the writer’s own experience of being instructed as an expert witness to provide opinions of the validity of such marriages, and partly on evidence from reported cases at different levels of the judicial system. The evidence demonstrates that decision making in this area, whether by officials or judges, often takes place in arbitrary ways, arguably to fulfil wider aims of controlling the immigration of certain population groups whose presence in the UK and Europe is increasingly seen as undesirable. However, and quite apart from the immigration control concerns underlying such actions, the field throws up evidence of the kinds of legal insecurity faced by those whose marriages are solemnized under non-Western legal traditions and calls into question respect for those traditions when they come into contact with Western officialdom.

    Proceeding from the suggestion of the Bundesrat (Deutscher Bundestag, Document 9/1851) concerning the draft of Rules of the Administrative Courts (VwGO), according to which original jurisdiction of the Higher Administrative Court (OVG) is to be introducing legel actions concerning the licensing of large scale installations in the field of energy, the author points out the now existing regulations and former ones in administrative jurisdiction and criminal jurisdiction by which legal protection is limited to a court of first instance which is competent for fact-finding (e.g. sec. 138 Para. 1 Act of compulsory consolidation of the boundaries of land (FlurbG), sec. 47 Rules of the Administrative Courts (VwGO), sections 24 Para. 1 No. 3, 74 Para. 1 p. 2 Judicature Act (GVG). He tries to transfer the idea of accelerating legal procedure from the model of the Criminal Court in criminal jurisdiction to administrative jurisdiction. Finally, the author examines the question whether cutting down the length of proceedings is really necessary, or if the same result could be reached by making an appeal subject to special admission.

  12. Regulating (for the benefit of) future persons: a different perspective on the FDA's jurisdiction to regulate human reproductive cloning.

    Science.gov (United States)

    Javitt, Gail H; Hudson, Kathy

    2003-01-01

    The Food and Drug Administration (FDA) has taken the position that human reproductive cloning falls within its regulatory jurisdiction. This position has been subject to criticism on both procedural and substantive grounds. Some have contended that the FDA has failed to follow administrative law principles in asserting its jurisdiction, while others claim the FDA is ill suited to the task of addressing the ethical and social implications of human cloning. This Article argues, that, notwithstanding these criticisms, the FDA could plausibly assert jurisdiction over human cloning as a form of human gene therapy, an area in which the FDA is already regarded as having primary regulatory authority. Such an assertion would require that the FDA's jurisdiction extend to products affecting future persons, i.e., those not yet born. This Article demonstrates, for the first time, that such jurisdiction was implicit in the enactment of the 1962 Kefauver-Harris Amendments to the Federal Food, Drug, and Cosmetic Act and that the FDA has historically relied on such authority in promulgating regulations for drugs and devices.

  15. Liquefied Natural Gas Storage of Variable Composition / Magazynowanie Skroplonego Gazu Ziemnego O Zmiennym Składzie

    Thanks to the increasing diversification of LNG supply sources, being a result of the growing number of LNG liquefaction installations over the World, increase of short-term trade contracts and general trend to globally liberalize gas markets, reception terminals have to cope with the broad range of qualitatively diversified LNG deliveries from various sources. Different LNG deliveries potentially have different density caused by different gas composition. Although the LNG composition depends on LNG source, it mainly consists of methane, ethane, propane, butane and trace nitrogen. When a new supply of LNG is transported to the tank, the LNG composition and temperature in the tank can be different from LNG as delivered. This may lead to the liquid stratification in the tank, and consequently the rollover. As a result, LNG rapidly evaporates and the pressure in the tank increases. More and more restrictive safety regulations require fuller understanding of the formation and evolution of layers. The paper is focused on the analysis of liquid stratification in the tank which may take place when storing LNG, and which process leads to the rapid evaporation of considerable quantities of LNG. The aim was to attempt modeling of the process of liquid stratification in an LNG tank. The paper is closed with the results of modelling. Dzięki rosnącej dywersyfikacji źródeł dostaw LNG, spowodowanej zwiększającą się liczbą instalacji skraplania gazu na całym świecie, wzrostem ilości kontraktów krótkoterminowych w handlu i ogólnej tendencji do globalnej liberalizacja rynków gazu, terminale do odbioru muszą radzić sobie z coraz większą gamą różnych jakościowo dostaw LNG z różnych źródeł. Różne dostawy LNG mają potencjalnie inną gęstość dzięki różnym składom gazu. Chociaż kompozycja LNG zależy od źródła, to przede wszystkim składa się z metanu, etanu, propanu, butanu i w śladowych ilościach z azotu. Gdy nowa dostawa LNG jest doprowadzana do zbiornika, skład i temperatura LNG już w zbiorniku może być inny niż dostarczanego. Może to prowadzić do rozwarstwienia cieczy w zbiorniku, a w konsekwencji wystąpienia zjawiska znanego jako "rollover". W wyniku tego zjawiska następuje gwałtowne odparowanie LNG i nagły wzrost ciśnienia w zbiorniku. Coraz bardziej restrykcyjne przepisy dotyczące bezpieczeństwa wymagają pełniejszego zrozumienia zjawiska tworzenia i ewolucji warstw. W artykule przeprowadzono analizę procesu rozwarstwienia cieczy w zbiorniku, mogącego wystąpić podczas magazynowania skroplonego gazu ziemnego, a prowadzącego do gwałtownego odparowania znacznych ilości LNG. Celem była próba modelowania procesu powstawania rozwarstwienia się cieczy w zbiorniku LNG. Przedstawione zostały wyniki modelowania tego zjawiska
