    1985-10-01

    Many approaches to designing software systems have been developed for use in commercial or business environments. These development methods and procedures have improved dramatically over the last ten years although it is only recently that these have been employed in scientific and technological applications. Many of these implementations have been unsuccessful because the design methodology has been divorced from the practical requirements of the industry in which the software system is to operate. This paper discusses a modern approach to software development which directly relates to an engineering environment and which is designed to satisfy practical criteria of acceptability of the software when delivered to the petroleum engineer. Since all field developments nowadays rely heavily on associated software systems, the approach presented here can lead to improved mechanical systems reliability and shorter development/design cycles.

    International Nuclear Information System (INIS)

    Geostatistics is a common tool in reservoir characterisation. Several texts discuss the subject, however this book differs in its approach and audience from currently available material. Written from the basics of statistics it covers only those topics that are needed for the two goals of the text: to exhibit the diagnostic potential of statistics and to introduce the important features of statistical modeling. This revised edition contains expanded discussions of some materials, in particular conditional probabilities, Bayes Theorem, correlation, and Kriging. The coverage of estimation, variability, and modeling applications have been updated. Seventy examples illustrate concepts and show the role of geology for providing important information for data analysis and model building. Four reservoir case studies conclude the presentation, illustrating the application and importance of the earlier material. This book can help petroleum professionals develop more accurate models, leading to lower sampling costs

  19. Engineering geology studies in the National Petroleum Reserve, Alaska

    Kachadoorian, Reuben; Crory, F.E.

    1984-01-01

    Engineering geology studies were conducted in direct support of the exploration program in the National Petroleum Reserve, Alaska. The studies included laboratory and field tests and observations to address design and construction problems of airfields, roads, drill pads and foundations, and to evaluate their actual performance. Permafrost containing large amounts of near surface ground ice as wedges, masses, and intergranular ice, required that all construction activity not disturb the thermal regime of the ground surface, which could lead to thaw of permafrost and ground subsidence. Summer activity, therefore was not allowable, yet the winter climate was so harsh that winter work was slow and inefficient. To allow summer operations at well sites planned for all year activity, it was necessary to adapt existing techniques for arctic construction and to devise new ones. The design and construction of facilities at the deep exploration wells at Inigok, Tunalik, and Lisburne posed the greatest challenge. These sites, requiring a year or more to drill, could only be attempted if continuous access to drilling and logistic supplies could be assured throughout the year, including the possibility of bringing in another drill rig, in the event of a blowout. Thus all-seasons airstrips were required at these wells. Sufficient quantities of local gravel were not readily available at the Inigok and Tunalik sites to construct the airstrips with the required 6 feet or more of gravel to prevent the underlying permafrost from thawing. Therefore, insulation was used to maintain the subbase of local sands in a continuously frozen state, which in turn was overlain by 15 inches of gravel or sandy gravel. Tests at the U.S. Army Waterways Experimental Station defined the minimum thickness of gravel required above the insulation to provide the desired bearing capacity for the C-130 type aircraft without crushing the insulation. Field testing also included the evaluation of another design

  1. The internal combustion engine; a simple solution for pollution from petroleum hydrocarbons

    International Nuclear Information System (INIS)

    The internal combustion (IC) engine is an indirect cause of groundwater and soil contamination from petroleum hydrocarbons. Leaking underground storage tank systems that are used to store and distribute fuel for automobiles are a major cause of environmental degradation. That same IC engine which has indirectly caused the pollution is an excellent tool for cleaning up environmental contamination from petroleum releases. An extremely flexible clean-up system using an IC engine was designed, constructed and operated to recover free product, treat contaminated soil and remediate groundwater pollution. The treatment system uses the IC engine for vapor extraction, groundwater pumping, spray aeration and incineration. The IC engine is an excellent incinerator. The petroleum vapors are burned in the IC engine with a supplemental propane fuel. The engine drives a power-takeoff unit and provides energy for an air compressor, water pump, electrical generation and other accessories. Using waste to energy methods multiple techniques are being used in combination with different treatment technologies to optimize the remediation. As the remediation progresses the treatment system can be modified to use additional techniques. Another benefit that is directly associated with the IC engine is the presence of excess heat which is helpful in northern climates. The excess heat has many uses including spray aeration and enhanced biological remediation. The IC engine has several limitations and requires an understanding of the physical and chemical properties of the contamination. As with all environmental remediation, a proper understanding of the Hydrogeological System is critical. When properly applied the IC engine has many advantages over other methods of remediation for petroleum hydrocarbons

  9. Deregulation of petroleum product prices: The case of India

    International Nuclear Information System (INIS)

    Deregulation of petroleum product prices has been considered for quite some time in India. Such a policy is compatible with the idea of a liberalized economy and reduced government intervention. However, little progress has been made so far, due to various issues that loom over the deregulation process. This paper analyses issues related to deregulation of petroleum product prices, clarifies certain conceptions or misconceptions, and studies the options available for a deregulated price environment. It is argued that the equity and environmental effects of kerosene use need to be borne in mind, and a simple cross-subsidy system to this effect is proposed. For all other products, a deregulated system with some safeguards may be feasible. The success of any such attempt, however, needs some institutional rearrangements. (author). 47 refs, 1 tab

  10. A Typical Case Study: Solid Waste Management in Petroleum Refineries

    Directory of Open Access Journals (Sweden)

    Jadea S. Alshammari

    2008-01-01

    Full Text Available The current environmental concerns have forced developed and developing countries to reduce air, water and land pollution for sustainable growth. Solid refinery waste is cocktail of hydrocarbons, water, heavy metal and fine solids and is substantial in quantity. The principal processes of waste management focus mainly on waste source reduction, reusing, recycling, composting, incineration with or without energy recovery, fuel production and land filling. Waste management models have a common approach of assignment of generating sources to landfills, transfer stations sitting, site selection for landfills, etc. but recently new integrated models have been developed and applied. Waste management system in an industrial complexes uses multi-objective mixed integer programming approach for the running of existing facilities in dynamic net work flow models with nonlinear costs of management. The latest multi-objective mixed integer programming techniques are applied to resolve the potential conflict between environmental and economic goals and to evaluate sustainable strategies for waste management. In this approach, material recycling in an economic sense exhibits huge indirect benefits, although the emphasis of environmental quality as a major objective in decision-making drives the optimal solution toward pro-recycling programs. The use of grey and fuzzy system theories as uncertainty analysis tools as an enhancement of this modeling analysis proves to be highly profitable. A multi-objective optimization model based on the goal programming approach has been developed and tested in this study for passable management of solid waste generated by a typical petroleum refining industry in the state of Kuwait. The analytic hierarchy process, a decision-making approach, including qualitative and quantitative aspects of a problem, has been integrated in the model to prioritize the conflicting goals existing in the waste management problems of the petroleum

In this investigation, a single cylinder, vertical, air-cooled diesel engine was modified to use liquid petroleum gas in dual fuel mode. The liquefied petroleum gas, was mixed with air and supplied through intake manifold. The liquid fuel neem oil or diesel was injected into the combustion chamber. The performance, emission, and combustion characteristics were studied and compared for neat fuel and dual fuel mode. The experimental results on dual fuel engine show a reduction in oxides of nitrogen up to 70% of the rated power and smoke in the entire power range. However the brake thermal efficiency was found decreased in low power range due to lower calorific value of liquid petroleum gas, and increase in higher power range due to the complete burning of liquid petroleum gas. Hydrocarbon and carbon monoxide emissions were increased significantly at lower power range and marginal variation in higher power range.

    Contamination of soil by petroleum products is a current problem in several countries in the world. In Algeria, this negative phenomenon is highly remarked in Saharan region. Numerous studies at the University of Ouargla that we will review in this paper, have tried to find an effective solution to eliminate the hydrocarbons from the soil by the technique of "biodegradation" which is a natural process based on microorganisms such as Bacillus megaterium and Pseudomonas aeruginosa. Presence of aboriginal strain Bacillus megaterium in the soil samples with different ages of contamination has shown a strong degradation of pollutants. This strain chosen for its short time of generation which is performing as seen the best yields of elimination of hydrocarbons assessed at 98 % biostimule by biosurfactant, also 98% on a sample wich bioaugmente by urea, and 86 % of the sample which biostimule by nutrient solution. The rate of biodegradation of the contaminated soil by crude oil using the strain Pseudomonas aeruginosa is higher in the presence of biosurfactant 53 % that in his absence 35 %. Another elimination technique wich is washing the contaminated soil's sample by centrifugation in the presence of biosurfactant where The rate of hydrocarbons mobilized after washing soil by centrifugation is of 50 % and 76 % but without centrifugation it was of 46% to 79%. Those processes have great capacity in the remobilization of hydrocarbons and acceleration of their biodegradation; thus, they deserve to be further developed in order to prevent environmental degradation in the region of Ouargla.

    Recycling waste materials produced in our daily life is considered as an additional resource of a wide range of materials and it conserves the environment. Used engine oil and used cooking oil are two oils disposed off in large quantities as a by-product of our daily life. This study aims at providing white bio oil, bio petroleum diesel and heavy fuel from the disposed oils. Toxic organic materials suspected to be present in the used engine oil were separated using vacuum column chromatography to reduce the time needed for the separation process and to avoid solvent usage. The compounds separated were detected by gas chromatography-mass spectrometry (GC-MS) and found to contain toxic aromatic carboxylic acids. Used cooking oils (thermally cracked from usage) were collected and separated by vacuum column chromatography. White bio oil produced was examined by GC-MS. The white bio oil consists of non-toxic hydrocarbons and is found to be a good alternative to white mineral oil which is significantly used in food industry, cosmetics and drugs with the risk of containing polycyclic aromatic compounds which are carcinogenic and toxic. Different portions of the used cooking oil and used engine were mixed to produce several blends for use as heavy oil fuels. White bio oil was used to produce bio petroleum diesel by blending it with petroleum diesel and kerosene. The bio petroleum diesel produced passed the PETRONAS flash point and viscosity specification test. The heat of combustion of the two blends of heavy fuel produced was measured and one of the blends was burned to demonstrate its burning ability. Higher heat of combustion was obtained from the blend containing greater proportion of used engine oil. This study has provided a successful recycled alternative for white bio oil, bio petroleum fuel and diesel which can be an energy source.

  18. Innovation and performance: The case of the upstream petroleum sector

    Science.gov (United States)

    Persaud, A. C. Jai

    This thesis investigates innovation in the upstream crude oil and natural gas sector, a strategic part of the Canadian economy and a vital industry for North American energy trade and security. Significant interest exists in understanding innovation in this sector from a private and public policy perspective. Interest in the sector has intensified recently due to concerns about world oil supply, Canada's oil sands development, and the potential that Canada may become an "energy superpower." The study examines the factors that drive companies involved in exploration, development, and production in the upstream petroleum sector to innovate and the impact of their innovation activities through major technologies on their performance. The thesis focuses on process innovation, which involves the adoption of new or significantly improved production processes, and is distinct from product innovation, which is based on the development and commercialization of a product with improved product characteristics to deliver new services to the consumer. The thesis provides a comprehensive review of the literature and develops an investigative model framework to examine the drivers of innovation and the impact of innovation on performance in the upstream petroleum sector. The research employs a survey questionnaire that was developed to obtain data and information, which was missing in the literature or not publicly available to test key relationships of innovation and performance indicators. In addition to the survey questionnaire, a number of knowledgeable experts in the industry were also interviewed. A total of 68 respondents completed the survey questionnaire, accounting for 40 percent of the firms in the industry. This percentage goes up to over 50 percent when account is taken of extremely small firms who could not fill out the survey. Further, the 68 respondents account for most of the industry revenues, production, and employment. The respondents include most of the key

    2005-01-01

    The geology and reservoir-engineering data were integrated in the 2002 U.S. Geological Survey assessment of the National Petroleum Reserve in Alaska (NPRA). VVhereas geology defined the analog pools and fields and provided the basic information on sizes and numbers of hypothesized petroleum accumulations, reservoir engineering helped develop necessary equations and correlations, which allowed the determination of reservoir parameters for better quantification of in-place petroleum volumes and recoverable reserves. Seismic- and sequence-stratigraphic study of the NPRA resulted in identification of 24 plays. Depth ranges in these 24 plays, however, were typically greater than depth ranges of analog plays for which there were available data, necessitating the need for establishing correlations. The basic parameters required were pressure, temperature, oil and gas formation volume factors, liquid/gas ratios for the associated and nonassociated gas, and recovery factors. Finally, the re sults of U.S. Geological Survey deposit simulation were used in carrying out an economic evaluation, which has been separately published. Copyright ?? 2005.

    Full Text Available The present work involves the synthesis of a petroleum-based fuel by the catalytic pyrolysis of waste plastics. Catalytic pyrolysis involves the degradation of the polymeric materials by heating them in the absence of oxygen and in the presence of a catalyst. In the present study different oil samples are produced using different catalysts under different reaction conditions from waste plastics. The synthesized oil samples are subjected to a parametric study based on the oil yield, selectivity of the oil, fuel properties, and reaction temperature. Depending on the results from the above study, an optimization of the catalyst and reaction conditions was done. Gas chromatography-mass spectrometry of the selected optimized sample was done to find out its chemical composition. Finally, performance analysis of the selected oil sample was carried out on a compression ignition (CI engine. Polythene bags are selected as the source of waste plastics. The catalysts used for the study include silica, alumina, Y zeolite, barium carbonate, zeolite, and their combinations. The pyrolysis reaction was carried at polymer to catalyst ratio of 10 : 1. The reaction temperature ranges between 400°C and 550°C. The inert atmosphere for the pyrolysis was provided by using nitrogen as a carrier gas.

  5. Combustion and exhaust emission characteristics of a compression ignition engine using liquefied petroleum gas-Diesel blended fuel

    International Nuclear Information System (INIS)

    Towards the effort of reducing pollutant emissions, especially smoke and nitrogen oxides, from direct injection (DI) Diesel engines, engineers have proposed various solutions, one of which is the use of a gaseous fuel as a partial supplement for liquid Diesel fuel. The use of liquefied petroleum gas (LPG) as an alternative fuel is a promising solution. The potential benefits of using LPG in Diesel engines are both economical and environmental. The high auto-ignition temperature of LPG is a serious advantage since the compression ratio of conventional Diesel engines can be maintained. The present contribution describes an experimental investigation conducted on a single cylinder DI Diesel engine, which has been properly modified to operate under LPG-Diesel blended fuel conditions, using LPG-Diesel blended fuels with various blended rates (0%, 10%, 20%, 30%, 40%). Comparative results are given for various engine speeds and loads for conventional Diesel and blended fuels, revealing the effect of blended fuel combustion on engine performance and exhaust emissions

In particular, a number of service systems engineering methods are identified toenhance the design and production/delivery of services, especially taking advantage of the uniquefeatures that characterize services - namely, services, especially emerging services, are information-driven, customer-centric, e-oriented, and productivity-focused.

  7. Measure of the volumetric efficiency and evaporator device performance for a liquefied petroleum gas spark ignition engine

    International Nuclear Information System (INIS)

    Highlights: ► Measure of the effect of LPG fuel on volumetric efficiency of a SI petrol ICE. ► Steady-state and transient performance of a LPG evaporator device on a SI ICE. ► Volume displaced by LPG causes slight performance loss in SI petrol engines. ► LPG reveals peak efficiency and high-efficiency range wider than petrol in SI ICE’s. ► One-stage pressure reducer for LPG performs satisfactorily during SI ICE transients. - Abstract: The use of Liquefied Petroleum Gas (LPG) as fuel for spark ignition engines originally designed to be gasoline fuelled is common practice in many countries. Despite this, some questions remain still open. The present paper deals with the two main problems related to LPG port-fuel SI engines: the volumetric efficiency drop and the LPG evaporator device performance. A passengers car SI engine equipped with a “third generation” kit for the dual-fuel operation was tested using a dynamometer test rig. A single-stage pressure reducer was selected as LPG evaporator, to take advantage of an additional pre-heating of the liquid LPG that allows higher power output than a two-stage device of the same size. Engine performance, volumetric efficiency and change of LPG thermodynamic states in the evaporator were measured both in steady-state and transient operation of the engine. Steady-state measurements show the advantage of LPG in terms of engine efficiency, and quantify the drop in steady-state brake torque due to the volume swept by gaseous fuel in the fresh charge admission process. On the other hand, transient measurements show that a single-stage evaporator device is capable to match overall simplicity and satisfactory performance during strong changes in engine load.

  8. Interface modeling to predict well casing damage for big hill strategic petroleum reserve.

    2012-02-01

    Oil leaks were found in well casings of Caverns 105 and 109 at the Big Hill Strategic Petroleum Reserve site. According to the field observations, two instances of casing damage occurred at the depth of the interface between the caprock and top of salt. This damage could be caused by interface movement induced by cavern volume closure due to salt creep. A three dimensional finite element model, which allows each cavern to be configured individually, was constructed to investigate shear and vertical displacements across each interface. The model contains interfaces between each lithology and a shear zone to examine the interface behavior in a realistic manner. This analysis results indicate that the casings of Caverns 105 and 109 failed by shear stress that exceeded shear strength due to the horizontal movement of the top of salt relative to the caprock, and tensile stress due to the downward movement of the top of salt from the caprock, respectively. The casings of Caverns 101, 110, 111 and 114, located at the far ends of the field, are predicted to be failed by shear stress in the near future. The casings of inmost Caverns 107 and 108 are predicted to be failed by tensile stress in the near future.

    2010-07-01

    This paper discussed approaches to tank farm ground improvement via 3 Canadian ground improvement case histories in order to set forth the advantages of ground improvement for foundation support at petroleum storage tank facilities. Each case study featured a particular set of site conditions, performance criteria, and ground improvement techniques selected to attain the desired foundation performance. The first case study involved a Vibro Replacement stone column to meet strict seismicity requirements, the second employed Dynamic Compaction to mitigate deep variable fill within a former gravel pit, and the last encompassed Vibro Compaction applied to a site with a sand fill soil profile. The site conditions, the design requirements, the ground improvement solution, the execution, and the quality control techniques and results were presented for each case history. Soil reinforcement and ground improvement to treat loose and soft soils below heavy storage tanks can be an economical solution to foundation design challenges. However, it is important to select proper methods and tailor the densification programs to the specific subsoil conditions and design requirements. In each application, the selected ground improvement technique exceeded the specified in-situ testing requirements. 3 refs., 9 figs.

  15. Insecurity of petroleum supplies and external effect: the case of security storage

    International Nuclear Information System (INIS)

    The public intervention in the domain of security of petroleum supplies is in general justified in the literature by the existence of external effects linked with the phenomenon of insecurity of supplies. This work proposes to analyse in detail the validity of this justification and its implication in terms of energy policy recommendations. The components of the insecurity cost is analyzed in the first part. Two components are retained: the macro-economical effects of insecurity and the monopsony cost. The study of the macro-economical component of insecurity uses a disequilibrium economy-type approach. On the basis of a modeling of the macro-economical effects of insecurity on a conventionalized economy, a relation is evidenced between rupture probability and level of usefulness. This model is applied to 4 European Union countries and the effects of supplies insecurity is measured for each of them. For the monopsony component of supplies insecurity, the additional cost generated by insecurity in relation with the monopsony situation is analyzed. A numerical analysis illustrates this analysis. Then, the relevance of the monopsony concept in the description of the situation of petroleum consuming economies is questioned. The analysis of the US case leads to reject the existence of a petroleum monopsony made of the USA alone and to favour the definition of a monopsony made of the IEA member countries. Then, the analysis of the insecurity cost is made using the external cost notion. This study allows to settle the status of the macro-economical component: there effectively exists a macro-economical cost of insecurity but this cost cannot be considered as external. This result is interesting because many analyses justify the public intervention using the external cost property of the macro-economical effects. On the contrary, the monopsony component can be unambiguously identified as being at the origin of a pecuniary external cost. The insecurity of supplies can be

  16. Catalyst light-off behavior of a spark-ignition LPG (liquefied petroleum gas) engine during cold start

    International Nuclear Information System (INIS)

    The effects of the length of the gas flow path from the exhaust outlet in the cylinder head to the catalyst inlet in the exhaust line, the ignition timing and the engine idle speed on the three-way catalyst light-off behavior in an electronically controlled inlet port LPG (liquefied petroleum gas) injection SI (spark-ignition) engine during cold start were investigated experimentally. The results showed that these factors affect the catalyst light-off behavior significantly during cold start. The reduction of the gas flow path length upstream the catalyst reduces the heat loss from the exhaust gases, increases the temperature of the catalyst, and results in faster catalyst light-off. Retarding the ignition timing from 0 to 15oCA ATDC decreases 22 and 8 s catalyst light-off time for HC and CO respectively. Increasing the engine idle speed from 1400 to 1800 rpm decreases 19 and 15 s the light-off time for HC and CO respectively. -- Research highlights: → The evaluation methods of the temperature and conversion efficiency are essential for catalyst light-off. → We adopt HC and CO emission to explain the catalyst light-off during cold start. → The reduction of the gas flow path length upstream, retarding the ignition timing and increasing the engine idle speed can reduce the catalyst light-off time during cold start. → We concluded that improving methods for catalyst light-off are essential for the catalyst light-off behavior during cold start.

    CONOCOPHILLIPS views Social Investment as an important element of contributing to social progress and achieving its view of Sustainable Growth. According to CONOCOPHILLIPS a company's ability to grow depends not only on its business successes but also on its reputation as a corporate citizen. This reputation is built largely by responsible civic actions, social investment and environmental stewardship. The company invests in programs that provide sustainable community development, benefit the stakeholders, are aligned with its strategic business objectives, and are consistent with its core values. CONOCOPHILLIPS recognizes that the most effective corporate social investment is achieved by pro actively identifying the key community needs and by entering into strategic partnerships with agencies and organizations that serve good causes. In Rio de Janeiro, Phillips Petroleum do Brasil, a subsidiary of CONOCOPHILLIPS, has been working with Projeto Uere, a non-profit non-governmental organization (NGO) that runs an educational program for children living under social risk in Favela da Mare. Projeto Uere performs preventive work, helping children overcome their learning and social difficulties. The Projeto Uere case study results will highlight the application of some of CONOCOPHILLIPS social investment policies and strategies used to select and evaluate partnership projects in Brazil.

  1. Petroleum investment opportunities in Manitoba - a geological, engineering and economic perspective

    International Nuclear Information System (INIS)

    Geology and reservoir characteristics of Manitoba's producing horizons were described, and recent activity in exploration and development prospects for the immediate future were reviewed. These prospects have improved considerably, thanks to recent efforts of the Manitoba Department of Energy and Mines to ensure that barriers to petroleum investment are eliminated. As a result of these and related efforts by the Manitoba government the investment climate is stable and competitive. Advantages in Manitoba include availability of Crown land at comparatively low prices, drilling and exploration incentives, low drilling and completion costs, and easy access to markets. Development drilling opportunities exist for each of Manitoba's five producing formations (the sandstones of the Jurassic Melita and Amaranth formations, and the Mississippian Bakken Formation, and the carbonates of the Mississipian Lodgepole and Mission Canyon formations). Sample economic scenarios run on three development scenarios and modelled after typical Manitoba oil play were very favorable, indicating a potential rate of return on investments of 25 to 37 per cent and pay-out in 2.6 to 3.2 years. 10 refs., 7 tabs., 5 figs

  2. Petroleum investment opportunities in Manitoba: A geological, engineering and economic perspective

    International Nuclear Information System (INIS)

    The geology and reservoir characteristics of Manitoba's oil producing horizons are described, and exploration and development prospects are reviewed. Southwestern Manitoba occupies part of the northeastern flank of the Williston Basin. Paleozoic, Mesozoic, and Cenozoic rocks form a basinward thickening wedge of sedimentary strata that reach a total thickness of 2,300 m in the southwest corner of the province. To date, oil production in Manitoba is restricted to the sandstones of the Middle Jurassic, the Jurassic Amaranth Formation, the Mississippian Bakken Formation, and the carbonates of the Mississippian Lodgepole and Mission Canyon Formations. The deeper Ordovician, Silurian, and Devonian formations offer oil and gas potential but remain largely undrilled. Total recoverable reserves are ca 36 million m3 and remaining proved reserves are ca 6 million m3. Manitoba had a resurgence in petroleum activity in 1993; 102 wells were licensed, compared to an annual average of 61 over the past five years. More Crown land was disposed at the two lease sales in 1993 than had been leased in the previous five years. Low Crown land price is one competitive advantage available to Manitoba oil producers. Other advantages include low drilling and completion costs, low drilling density, a competitive and stable fiscal regime, drilling and exploration incentives, and unrestricted access to markets. Sample economics are included to illustrate the attractiveness of vertical and horizontal drilling opportunities in Manitoba. 8 refs., 6 figs., 7 tabs

    Full Text Available In situ and ex situ bioremediation of oil contaminated effluent pits, sludge pits, oil spilled land and tank bottom, and effluent treatment plant (ETP oily sludge was carried out at Ankleshwar, Mehsana, Assam and Cauvery Asset of Oil and Natural Gas Corporation Limited (ONGC, India. The types of contaminant were heavy paraffinic, asphaltic and light crude oil and emulsified oily sludge /contaminated soil. An indigenous microbial consortium was developed by assembling four species of bacteria, isolated from various oil contaminated sites of India, which could biodegrade different fractions of total petroleum hydrocarbon (TPH of the oily waste to environment friendly end products. The said consortium was on a large scale field applied to the above oil installations and it successfully bioremediated 30,706 tonnes of different types of oily waste. In 65 case studies of different batch size of in situ and ex situ bioremediation processes, the initial TPH content varying from 69.20 to 662.70 g/kg of oily waste has been biodegraded to 5.30 – 16.90 g/kg of oily waste in a range of 2 to 33 months. Biodegradation rate varied in the range of 0.22 – 1.10 Kg TPH /day/m2 area due to the climatic condition of the treatment zone and the type of waste treated. The bioremediated soil was non-toxic and natural vegetation was found to be grown on the same ground. Successful eco-restoration of one large effluent pit of 26,000 m2 area was carried out by cultivation of local fish species after completion of bioremediation. Bioremediation technology has helped ONGC with the management of their hazardous oily wastes in an environment friendly manner. DOI: http://dx.doi.org/10.5755/j01.erem.68.2.5632

    Little is known about the magnitude of the effect of powerful tropical storms on asset prices, or when markets revise price expectations in response to such storms. Refinery clustering in the coastal northwest Gulf of Mexico provides an opportunity to examine such effects directly. We examine the effect of tropical storm forecasts on the crack spread - the difference between refined petroleum and crude oil prices. Prices appear to reflect storm effects at the 24-h forecast horizon. Further, the magnitude is significant - category 4 hurricanes in this region increase refined petroleum prices relative to crude oil by about 13.5%. (author)

    International Nuclear Information System (INIS)

    The objective of this study includes the identification of possible causes of fires and explosions resulting from liquefied petroleum gases in Khartoum state, method of raising the awareness and knowledge of risks resulting from them, in addition to the proposal of safety precautions in the event of such incidents. The study was conducted in highly populated Khartoum state. It was in that context, the compilation and analysis of information on fire statistics was carried based on data collected through field studies and records of the civil defense - Administrative of Khartoum state, during period between (2007 - 2009). The procedure followed include statistical analysis of the collected data using program (e-views) method of estimation of least squares (LS). The obtained results of this method is negative sign and the percentage of house fires represent 98% from other type of fires (petroleum service stations - LPG tankers). These results, revealed that most of those fires were due to leakage of gas in residential houses attributed to lack of awareness of possible dangers and underestimation of safety precautions compared to those taken in to consideration in petroleum service stations and during transportation phases. The main recommendation of this study is to strengthen means of raising public awareness of dangers caused by liquefied petroleum gases fire through special media programs and training of workers in the field of civil defense and the empowerment of safety procedures.

  15. Case studies using the United States Coast Guard's Oil Identification System for petroleum spill source identification

    International Nuclear Information System (INIS)

    The Oil Identification System (OIS) was developed in the 1970's at the Coast Guard Research and Development Center, to determine the unique, intrinsic properties which would allow the matching of a spilled oil with its correct source. The Central Oil Identification Laboratory (COIL) was established in 1978 as the operating facility to implement the OIS. The OIS encompasses four analytical methods; thin layer chromatography, fluorescence spectroscopy, infrared spectroscopy and gas chromatography. A sample can be studied according to each individual method or multi-methods approach can be chosen if no single technique gives unequivocal results. Combined these methods are greater than 99% effective. The authors recently utilized the OIS and the COIL for three petroleum spill investigations in New York. As part of the investigation to determine the source(s) of several different petroleum product spills, OIS was conducted along with a review of groundwater sample chromatograms

    Full Text Available CASE tools are having an important role in all phases of software systems development and engineering. This is evident in the huge benefits obtained from using these tools including their cost-effectiveness, rapid software application development, and improving the possibility of software reuse to name just a few. In this paper, the idea of moving towards E-CASE tools, rather than traditional CASE tools, is advocated since these E-CASE tools have all the benefits and advantages of traditional CASE tools and add to that all the benefits of web technology. This is presented by focusing on the role of E-CASE tools in facilitating the trend of telecommuting and virtual workplaces among software engineering and information technology professionals. In addition, E-CASE tools integrates smoothly with the trend of E-learning in conducting software engineering courses. Finally, two surveys were conducted for a group of software engineering professional and students of software engineering courses. The surveys show that E-CASE tools are of great value to both communities of students and professionals of software engineering.

    @@ Successful textbooks educate generations,and in a way define generations of scientists. As science and technology advance,textbooks become old and outdated. Nevertheless, each textbook serves as a foundation for the next, and thus a series of textbooks on a particular subject reflects the evolution of concepts, methods and data on the subject. As I write this review, there are eight textbooks on petroleum geology on my bookshelf: D. Hager's Practical Oil Geology (1915) (the first textbook of its kind); W.H. Emmons' Geology of Petroleum (1921), Cecil Lalicker's Principles of Petroleum Geology (1949); William Russell's Principles of Petroleum Geology (1951); Kenneth Landes' Petroleum Geology (1951); A. I. Levorsen's Geology of Petroleum (2nd ed., 1967); F. K. North's Petroleum Geology (1985); and Richard Selley's Elements of Petroleum Geology (2nd ed., 1998). Petroleum Geoscience by Gluyas and Swarbrick is a welcome addition to this list although its authors do not mention their predecessors.

    Case-based reasoning (CBR) is a kind of analogous reasoning that is widely used in artificial intelligence. Conflicts are pervasive in Concurrent Engineering design environment. Conflict negotiation is necessary when conflicts occur. It is difficult to resolve conflicts due to several reasons. An approach to resolving conflicts by case-based reasoning is proposed in this paper. The knowledge representation of conflict negotiation cases, the judgment of case similarity, the retrieval model of cases, the management of case bases, and the process of case-based conflict negotiation are studied. The implementation structure of the Case-based Conflict Solving System (CCSS) is also given.

    2007-09-01

    This research documents the analysis and interpretation of selected Carbonaceous Chondrites (CC) including Murchison, Allende, NWA 3003, Dhofar 735, Orgueil, Tagish Lake and Vigarano using organic petrology, scanning electron microscopy, and petroleum geochemistry. The kerogen microstructures and bitumen within CCs closely resemble remnant 2.5 Ga terrestrial microbial-like structures and their biodegraded components and solid bitumen. In both instances, organoclasts are associated with framboidal iron sulfides or oxides and clay-like minerals. The organic-rich kerogens within three CCs (especially Murchison) might have served as petroleum source rocks for the early generation of hydrocarbons. The maturity varies between 0.7% (Orgueil) and 1.24% (Murchison), to 5.1 % Ro (Vigarano) with predicted maturation temperatures of 100° to 475°C. Geochemical analysis of selected CCs (Murchison, Orgueil, and Tagish Lake) reveal the organic richness and the presence of low molecular weight n-alkanes (C 10 to C 20), complex cyclo-and isoalkanes, nonhydrocarbons, elemental sulfur with abundant aromatic compounds, most of them similar to bacterial and algal derived petroleum products. Apart from the concept of panspermia, the data highlights that three CCs sustained a formation temperature (oil biomarkers. Therefore, the authors propose a model of a "universal unconventional petroleum system", which implies a prospect of oil and gas within the Martian environment and elsewhere within the Solar System.

  5. Biopiles for remediation of petroleum-contaminated soils: a Polish case study

    International Nuclear Information System (INIS)

    The US Department of Energy and the Institute for Ecology of Industrial Areas of Poland demonstrated bioremediation techniques for the clean up of acidic petroleum sludge impacted soils at an oil refinery in southern Poland. The waste was composed of high molecular weight paraffinic and polynuclear aromatic hydrocarbons. Benzo(a)pyrene and BTEX compounds were identified as the contaminants of concern. Approximately 3,300 m3 of contaminated soil (TPH ∼ 30,000 ppm) was targeted for treatment. A biopile design which employed a combination of passive and active aeration in conjunction with nutrient and surfactant application was used to increase the biodegradation of the contaminants of concern. Over the 20 month project, more than 81% (120 metric tons) of petroleum hydrocarbons were biodegraded. Despite the fact the material treated was highly weathered and very acidic, biodegradation rates of 121 mg/kg soil/day in the actively aerated side (82 mg/kg soil/day in the passive side) were achieved in this biopile. Microbial counts and dehydrogenase measurements gave the best correlation with the biodegradation rates. Costs were competitive or significantly lower when compared with other ex situ treatment processes. (author)

  6. Partnership in an application of RBCA: Case study for quantitative assessment of total petroleum hydrocarbons

    International Nuclear Information System (INIS)

    Risk-Based Corrective Action (RBCA) was successfully applied at a site contaminated with weathered Total Petroleum Hydrocarbons (TPH) from a past release of Diesel Fuel No. 2. In partnership with the state regulatory agency, an approach was developed to assess the toxicity of TPH by the evaluation of its individual classes/constituents. Historically, assessments of petroleum product releases have focused solely on TPH as an analytical parameter and not its individual fractions and/or constituents which represent the actual toxicity of the released product. Soil and groundwater TPH data by Modified California Method 8015 (GC/MS) were reviewed. Based on analytical standards, typical Diesel Fuel No. 2 carbon ranges/fractions were identified. In addition, site-specific carbon-chain lengths were identified based on the aforementioned standard. In consultation with state regulators and according to state draft RBCA guidance, site-specific polycyclic aromatic hydrocarbons (PAHs) and three TPH carbon-range fractions were identified as constituents of concern. In order to quantify the three TPH fractions, appropriate toxicological surrogates were identified. Site-specific exposures to potential human and ecological receptors were evaluated in close consultation with the state regulators. Limited contaminant fate and transport analysis was conducted. Subsequently, complete exposure pathways were quantified

    AMANDA H.L. CHEE

    2010-06-01

    Full Text Available Petroleum refining process produces a large amount of atmospheric pollutants including greenhouse gases which are attributed to global warming. The international community inevitably addressed the global warming issue by introducing a market-based mechanism known as Emission Trading Systems (ETS under the Kyoto Protocol which imposes binding limits to developed nations using three flexibility mechanisms, including the Clean Development Mechanism (CDM. This case study was carried out in a petroleum refinery in Malaysia to explore the possibility for the refinery to participate in CDM. Information was collected through observatory field survey at the refinery and documentation review. Results show that the current monitoring tool using indirect calculation of fuel consumption provides a comprehensive coverage of emission sources but the reporting frequency should be increased for data accuracy. An accounting system was then created to predict the emissions gap of the refinery with reference to the baseline-year set by the Kyoto Protocol. It was concluded that the refinery showed promising potential to participate in CDM to benefit from technology transfer by selling their ‘credits’ to Annex I countries despite the uncertainty on the impact of the carbon market in a Non-Annex I country.

  9. Damage-Tolerant Fan Casings for Jet Engines

    Science.gov (United States)

    2006-01-01

    All turbofan engines work on the same principle. A large fan at the front of the engine draws air in. A portion of the air enters the compressor, but a greater portion passes on the outside of the engine this is called bypass air. The air that enters the compressor then passes through several stages of rotating fan blades that compress the air more, and then it passes into the combustor. In the combustor, fuel is injected into the airstream, and the fuel-air mixture is ignited. The hot gasses produced expand rapidly to the rear, and the engine reacts by moving forward. If there is a flaw in the system, such as an unexpected obstruction, the fan blade can break, spin off, and harm other engine components. Fan casings, therefore, need to be strong enough to contain errant blades and damage-tolerant to withstand the punishment of a loose blade-turned-projectile. NASA has spearheaded research into improving jet engine fan casings, ultimately discovering a cost-effective approach to manufacturing damage-tolerant fan cases that also boast significant weight reduction. In an aircraft, weight reduction translates directly into fuel burn savings, increased payload, and greater aircraft range. This technology increases safety and structural integrity; is an attractive, viable option for engine manufacturers, because of the low-cost manufacturing; and it is a practical alternative for customers, as it has the added cost saving benefits of the weight reduction.

    2014-05-01

    Full Text Available The purpose of this paper was to determine whether tipping could reduce labour costs in the petroleum products retail sector. The research we present was designed on the basis of survey results gathered from Slovenian petrol stations in 2009 and 2010. We have identified the following factors in the tipping process: job satisfaction, flexibility, service quality, satisfaction, motivation and the factor of receiving tips. The analysis showed correlation between methods used to increase the value of tips and better service quality, increased financial and numerical flexibility, motivation, satisfaction upon receipt of tips and the method used to increase the value of tips. In order to decrease labour costs we propose that the management take control of tipping and integrates tips into the reward system. Also, the employees should be made aware about how tipping improves service and increases their income.

  12. Building Test Cases through Model Driven Engineering

    Science.gov (United States)

    Sousa, Helaine; Lopes, Denivaldo; Abdelouahab, Zair; Hammoudi, Slimane; Claro, Daniela Barreiro

    Recently, Model Driven Engineering (MDE) has been proposed to face the complexity in the development, maintenance and evolution of large and distributed software systems. Model Driven Architecture (MDA) is an example of MDE. In this context, model transformations enable a large reuse of software systems through the transformation of a Platform Independent Model into a Platform Specific Model. Although source code can be generated from models, defects can be injected during the modeling or transformation process. In order to delivery software systems without defects that cause errors and fails, the source code must be submitted to test. In this paper, we present an approach that takes care of test in the whole software life cycle, i.e. it starts in the modeling level and finishes in the test of source code of software systems. We provide an example to illustrate our approach.

    Adoption of advanced automated SE (ASE) tools would be more favored if a business case could be made that these tools are more valuable than alternate methods. In theory, software prediction models can be used to make that case. In practice, this is complicated by the 'local tuning' problem. Normally. predictors for software effort and defects and threat use local data to tune their predictions. Such local tuning data is often unavailable. This paper shows that assessing the relative merits of different SE methods need not require precise local tunings. STAR 1 is a simulated annealer plus a Bayesian post-processor that explores the space of possible local tunings within software prediction models. STAR 1 ranks project decisions by their effects on effort and defects and threats. In experiments with NASA systems. STARI found one project where ASE were essential for minimizing effort/ defect/ threats; and another project were ASE tools were merely optional.

  15. Case history of a toxicity identification/reduction evaluation (TI/RE) at a petroleum refinery

    International Nuclear Information System (INIS)

    During an operational turn-around at a high conversion petroleum refinery, the final wastewater effluent became toxic to three fish species used in continuous on-line flow-through acute toxicity tests. Discharge of effluent to the receiving bay was promptly halted. Wastewater treatment continued and the treated effluent was diverted to a series of holding ponds with limited capacity. A refinery team was formed to coordinate toxicity identification studies as well as to facilitate modifications of waste disposal practices and treatment operations. A test program was conducted, consisting of one rainbow trout Phase 1 TIE and 84 strategic acute toxicity tests. As a result, a treatment methodology was identified within three days and within eight days of first observing toxicity a cationic water treatment polymer was identified as the primary toxicant. The toxicity was due to increased bioavailability of the polymer when suspended solids loads dropped during turn-around. Use of the polymer was immediately stopped and discharge to the bay was resumed with 100% survival of all three monitoring species. The authors present an overview of the studies and decisions leading to the successful identification and management of this situation

    2013-01-01

    Full Text Available The high economic growth in the past few years and increasing industrialization coupled with a burgeoning population have created a lot of concern for India’s energy scenario. India’s crude oil production has not shown significant growth in the last 10 or more years whereas its refining capacity has grown by more than 20% over the last 5 years. Oil consumption is growing at approximately 4.1% per year and natural gas consumption is growing at 68% per year. Therefore, evaluation performances and pushing energy companies to improve become important issues. The purpose of this research is of evaluation the performance of Indian energy industry under multiple different inputs and outputs criteria. The data envelopment analysis (DEA and grey theory are used to conduct this study. There are total 14 public sector undertakings (PSUs under this industry and no any private company. However, only 10 of them are mature enough to be published in India stock markets. Therefore, the realistic data of all 10 companies are used for this evaluation. The results demonstrate that Gas Authority of India Limited (GAIL, Chennai Petroleum Corporation Limited (CPCL, and Oil India Limited (OIL are the top 3 of ranking influences. This integrated numerical study gives a better “past-present-future” insights into evaluation performance in India energy industry.

    Full Text Available Industrialization is highly desirable for the sustenance of a nation’s economy and the enhancement of the citizenry’s well being. However the negative impact precipitated by introduction of its unwanted by – products into ecological system may be catastrophic if allowed to build up and uncontrolled. Urban Air pollution due to activities of process industries is one of the main problems faced by the industrial area of the world. Experimental analysis was carried out on gas flare to determine the extent of air pollution by the petroleum refinery industry on the concentrations of NO, CO, SO2 and total hydrocarbon. Attempt at the modeling pollutant concentration from the flare point using visual basic is hereby presented. The model equation was used to simulate the concentration of pollutants at distance of 20, 40, 60, and 80, 100, to 1000 away from the flare point. The result of the simulation of model developed from the modified principle of gaseous dispersion by Gaussian showed a good agreement with the experimental results with average correction coefficient of 0.99. Results obtained reveled that the concentration of pollutants are unacceptable compare to the Federal Environmental protection Agency set limit. The dispersion pattern of pollutants showed that the extent of spreading is dependent on nearness to the source of flare, wind speed, temperature etc.

  18. Petroleum hydrocarbon contamination of groundwater in the vicinity of an oil refinery -- A case study

    International Nuclear Information System (INIS)

    Groundwater in the vicinity of an oil refinery in Algeria was found to be contaminated with petroleum hydrocarbons. Free floating product, which was found after analysis to be crude oil, was noticed in some of the domestic water supply wells, and also in some irrigation wells which were situated close to the refinery. It was observed that the water in none of the shallow dug wells was contaminated. On the other hand, most of the borewells had contaminated groundwater. The studies included detailed hydrogeological investigations, verification of all the installations carrying crude oil, such as reservoirs and pipe lines. Due to the huge withdrawals from the regional water supply wells, steep hydraulic gradients were observed towards the well field. By modifying the pattern of groundwater withdrawals in the area a provisional containment of the contamination was achieved. The above ground storage tanks were found to be heavily pitted, and corroded at the bottom. Nine monitoring wells were drilled around the storage tanks. Soil and groundwater samples were analyzed from these monitoring wells. From these analyses, the contaminant plume was delineated. Tracer tests in these monitoring wells were conducted to determine the groundwater flow direction. To remediate the problems, the existing crude oil tanks were verified, cleaned and painted with non corrosive paints; the contaminated wells were pumped and the water was treated in the normal treatment system installed at the refinery. Groundwater quality was monitored over a period of six months to ensure the quality of water

    2016-01-15

    In this study the influence of the petroleum products: diesel fuel and spent engine oil on the sewage sludge digestion process and biogas production efficiency was investigated. Microbiological, chemical and enzymatic analyses were applied in the survey. It was revealed that the influence of the petroleum derivatives on the effectiveness of the methane fermentation of sewage sludge depends on the type of the petroleum product. Diesel fuel did not limit the biogas production and the methane concentration in the biogas, while spent engine oil significantly reduced the process efficacy. The changes in physical-chemical parameters, excluding COD, did not reflect the effect of the tested substances. The negative influence of petroleum products on individual bacterial groups was observed after 7 days of the process, while after 14 days probably some adaptive mechanisms appeared. The dehydrogenase activity assessment was the most relevant parameter to evaluate the effect of petroleum products contamination. Diesel fuel was probably used as a source of carbon and energy in the process, while the toxic influence was observed in case of spent engine oil. PMID:26378365

  13. In situ bioremediation of petroleum hydrocarbons and chlorinated hydrocarbons: Three case studies

    International Nuclear Information System (INIS)

    In situ biodegradation of organic contaminants is one of the most cost-effective means of site remediation. This method has proven successful in soils, ground water, and slurries. Bacteria capable of degrading organic contaminants within an aquifer include many species from a wide spectrum of genera, e.g. Pseudomonas, Corynebacterium, Bacillus, etc. In most cases, a mixture of bacterial strains is required to completely oxidize a complex organic contaminant. Each strain of an organism may target a specific compound, working together with other organisms to ultimately degrade each intermediate until complete degradation, also known as mineralization, occurs. One or more of the following mechanisms are utilized by bacteria for organic chemical degradation: (1) aerobic, (2) anaerobic, and (3) co-metabolic. During aerobic oxidation of organic chemicals, bacteria utilize the pollutant as an electron and hydrogen source and oxygen acts as the electron and hydrogen acceptor, resulting in water. As the bacterial enzymes cleave the compound, oxidized products are produced along with energy for the reaction to proceed. This is the most rapid and widely utilized mechanism. Dehalogenation occurs under aerobic, or perhaps more often, under anoxic conditions. This process occurs in the presence of alternate electron acceptors and replaces chlorine with hydrogen. The mechanism of co-metabolism can be aerobic or anaerobic, but is more often aerobic. This process requires a separate energy source for the bacterial cell because the pollutant is not utilized as an energy source. The role of bioremediation in site remediation is demonstrated below by three case studies: (1) a refinery, (2) a municipal landfill and (3) a pesticide formulation plant

  14. The EED [Emergencies Engineering Division] solvent extraction process for the removal of petroleum-derived hydrocarbons from soil

    International Nuclear Information System (INIS)

    Research was conducted to investigate the ability of hexane and natural gas condensate (NGC) to extract three different types of hydrocarbon contaminant (light crude oil, diesel fuel, and bunker C oil) from three types of soil (sand, peat, and clay). A separate but related study determined the efficiency of solvent extraction (using hexane and five other solvents but not NGC) for removal of polychlorinated biphenyls (PCB) from contaminated soil. The process developed for this research includes stages of mixing, extraction, separation, and solvent recovery, for eventual implementation as a mobile solvent extraction unit. In experiments on samples created in the laboratory, extraction efficiencies of hydrocarbons often rose above 95%. On samples from a petroleum contaminated site, average extraction efficiency was ca 82%. Sandy soils contaminated in the laboratory were effectively cleaned of all hydrocarbons tested but only diesel fuel was successfully extracted from peat soils. No significant differences were observed in the effectiveness of hexane and NGC for contamination levels above 3%. Below this number, NGC seems more effective at removing oil from peat while hexane is slightly more effective on clay soils. Sand is equally cleaned by both solvents at all contamination levels. Safety considerations, odor, extra care needed to deal with light ends and aromatics, and the fact that only 26% of the solvent is actually usable make NGC an unfeasible option in spite of its significantly lower cost compared to hexane. For extracting PCBs, a hexane/acetone mixture proved to have the best removal efficiency. 14 refs., 14 figs., 7 tabs

  3. Petroleum apocalypse

    International Nuclear Information System (INIS)

    Oil prices are increasing while current explanations for this phenomenon are no longer satisfactory. The cheap petroleum era is ending and this problem can seriously convulse our lifestyles. Transports, agriculture, plastics, clothes, medicines: petroleum is everywhere. This is why the rise of hydrocarbons price will not be a simple economic shock but the end of the world like the one we know. However, it is still possible to postpone this event to a later date and to limit its effects by the implementation of a new oil sobriety era. This implies to already organize the decay of materials and energy consumption, together with keeping solidarity, democracy and peace up. In this condition only the transition will be less painful.

    The injection of liquid foreign materials such as petroleum jelly and paraffin oil was used as an early medical intervention for the augmentation of body contour in the late 19th century. These practices were associated with severe late onset complications and they have been abandoned by plastic surgeons today. This article discusses a male-to-female transsexual patient with an acute inflammatory response with early sclerosing lipogranuloma of breasts associated with the self-injection of large amounts of petroleum jelly. The inflammation is successfully controlled with the early administration of prophylactic broad-spectrum antibiotics, steroids, and nonsteroid anti-inflammatory agents followed by a subcutaneous mastectomy. The importance of medical education and psychology counseling is discussed. PMID:18360333

  7. The para-petroleum industry. International context and results of the 2005 French inquiry

    International Nuclear Information System (INIS)

    Oil companies rarely carry out themselves the important works planned in the framework of their investments or of the exploitation of their facilities. In most cases, they act as prime contractor and generate a huge market of equipments, services and engineering needs in which many companies of various size are involved and make the overall para-petroleum industry. The French position on this market was asserted very early thanks to the continuation of ambitious R and D programs, very often carried out in the framework of the CEP and M and of the COPREP, which have permitted to build and maintain a solid technological knowledge. In this context, the lack of regular statistical data about the French para-petroleum industry has led, since 1978, the group of para-petroleum and para-gas companies, the CEP and M and the former COPREP (now the Committee of petroleum and marine studies - CEP and M), and the French institute of petroleum (IFP), to launch an annual inquiry at the national scale. This document makes a brief overview of the international context of the petroleum industry and then presents the last results of the 2004 inquiry about the French para-petroleum industry. Some data are foreseen for 2005, based on the estimations supplied by the companies themselves. (J.S.)

    Full Text Available A microbiological assessment of soil polluted by refined petroleum was carried out in Eluama community, Isuikwuato LGA, Abia State, Nigeria between March and October, 2012. The aim of the study is to examine the long-term kinetics of refined petroleum oil contaminated soil in this area from pipeline vandalization in the year 2000 and to assess the extent of biodegradation with respect to length of time of the spill. The microbiological examination of the soil samples were conducted by serial diluting and then inoculating the soil samples on different growth media. Several microbiological and biochemical methods were applied in order to isolate and identify the microorganisms accustomed to the soil sample. An unpolluted farmland served as control. Results showed a decrease in microbial load of soil as distance approaches seepage area. The control has a total heterotrophic bacteria count of 22.3 x 106 CFU/ml which decreases towards the seepage area (4.1 x 106 CFU/ml. The total fungi count also decreases from the control (5.9 x 106 CFU/ml towards the seepage area (1.2 x 106 CFU/ml. Micococcus sp and Pseudomonas aeroginosa were predominant in the seepage area up to 30m away from the seepage area. Other bacteria identified after this distance include Bacillus sp, Klebsiella pneumonia, Streptomyces sp, Streptococcus sp and Staphylococcus aureus while the predominant fungi were Aspergillus niger and Mucor sp. The marked decrease of heterotrophic bacteria and fungi in the petroleum polluted area compared with the control (the unpolluted farmland shows the unsuitability of the soil for agricultural purpose, as full remediation has not taken place.

    Energy Technology Data Exchange (ETDEWEB)

    1993-02-16

    During 1992 the Department continued planning activities for the expansion of the Strategic Petroleum Reserve to one billion barrels. A draft Environmental Impact Statement for the five candidate sites was completed in October 1992, and a series of public hearings was held during December 1992. Conceptual design engineering activities, life cycle cost estimates and geotechnical studies to support the technical requirements for an Strategic Petroleum Reserve Plan Amendment were essentially completed in December 1992. At the end of 1992, the Strategic Petroleum Reserve crude oil inventory was 574.7 million barrels and an additional 1.7 million barrels was in transit to the Reserve. During 1992 approximately 6.2 million barrels of crude oil were acquired for the Reserve. A Department of Energy Tiger Team Environmental, Safety and Health (ES&H) Assessment was conducted at the Strategic Petroleum Reserve from March 9 through April 10, 1992. In general, the Tiger Team found that Strategic Petroleum Reserve activities do not pose undue environmental, safety or health risks. The Strategic Petroleum Reserve`s Final Corrective Action Plan, prepared in response to the Tiger Team assessment, was submitted for Department approval in December 1992. On November 18, 1992, the Assistant Secretary for Fossil Energy selected DynMcDennott Petroleum Operations Company to provide management and operating services for the Strategic Petroleum Reserve for a period of 5 years commencing April 1, 1993. DynMcDermott will succeed Boeing Petroleum Services, Inc.

  19. Energetic integration of processes: a case of practical application in the petroleum exploitation and production area in Mexico

    International Nuclear Information System (INIS)

    The energetic integration of processes also called Pinch technology has reached the maturity by means of its development and application in different parts of the world, producing enormous savings in energy and capital, nevertheless. In Latin America countries, particularly in Mexico, not much is done respect of its practical application, and for this reason, the majority of the industrial processes operate with high costs of energy and capital. The infrastructure of the Mexican Petroleum Industry represents a great potential to make efficient the use of materials and energetic resources. In this work, with a vision of saving energy and capital, the traditional process of crude oil dehydration is analyzed. By means of the application of Pinch technology there were proposed modifications to the existing process, intended for the saving of energy and capital and to avoid unnecessary consumption of cooling water.

  1. Ethical considerations in tissue engineering research: Case studies in translation.

    Science.gov (United States)

    Baker, Hannah B; McQuilling, John P; King, Nancy M P

    2016-04-15

    Tissue engineering research is a complex process that requires investigators to focus on the relationship between their research and anticipated gains in both knowledge and treatment improvements. The ethical considerations arising from tissue engineering research are similarly complex when addressing the translational progression from bench to bedside, and investigators in the field of tissue engineering act as moral agents at each step of their research along the translational pathway, from early benchwork and preclinical studies to clinical research. This review highlights the ethical considerations and challenges at each stage of research, by comparing issues surrounding two translational tissue engineering technologies: the bioartificial pancreas and a tissue engineered skeletal muscle construct. We present relevant ethical issues and questions to consider at each step along the translational pathway, from the basic science bench to preclinical research to first-in-human clinical trials. Topics at the bench level include maintaining data integrity, appropriate reporting and dissemination of results, and ensuring that studies are designed to yield results suitable for advancing research. Topics in preclinical research include the principle of "modest translational distance" and appropriate animal models. Topics in clinical research include key issues that arise in early-stage clinical trials, including selection of patient-subjects, disclosure of uncertainty, and defining success. The comparison of these two technologies and their ethical issues brings to light many challenges for translational tissue engineering research and provides guidance for investigators engaged in development of any tissue engineering technology.

    Since the physical and chemical characteristics of biogas, some problems such as slow combustion speed, uncompleted burned fuel and high exhaust temperature will occur in its applications in engine. The biogas engine model library was built with the object-oriented language Modelica, the performance of a four-stroke spark-ignition gas engine operating with natural gas/liquefied petroleum gas-biogas blends were investigated. Natural gas (33 %, 67 % and 100%) and liquefied petroleum gas (5%, 10% and 15%) were added to the biogas and were simulated as the fuel of SI engine. The effects of natural gas/liquefied petroleum gas-biogas blends on the performance of spark-ignition engine used for electricity production were numerical investigated, the results were validated through the experiments on a gasoline modified gas engine. The results suggest that: There is an improvement in brake thermal efficiency and brake powers with the addition of natural gas/liquefied petroleum gas in biogas. The feature of reusable and object-orien-ted of Modelica will enhance the modeling and simulation of biogas engine performance greatly not only in accuracy but simulation efficiency, this would be efficient for the design and the optimum work of the biogas fuelled engine.%针对由沼气成分及其理化特性导致的内燃机燃用沼气时会发生燃烧速度慢、后燃严重、排气温度高等问题,将生物质燃气内燃机作为研究对象,基于可重用性及面向对象的Modelica语言建立内燃机模型库,将生物质燃气为燃料对四缸四冲程火花点火内燃机性能进行分析.通过仿真研究不同比例天然气(体积分数分别为33%,67%及100%)和LPG(体积分数分别为5%,10%及15%)对内燃机性能的影响,并在一台原汽油机改装的生物质燃气内燃机进行实验验证.结果表明:随着天然气/LPG的加入,内燃机的热效率及功率有所提高,且随着生物质燃气中天然气/LPG体积分数的增加,内

    Full Text Available Mining engineering involves the design, planning and management of operations for the development, production and eventual rehabilitation of resource extraction. These activities draw on a diverse set of skills. University of British Columbia mining engineers have traditionally been highly regarded for their strengths in the technical aspects of mining and mineral process but also for their understanding of the application of principles of sustainability and social responsibility. The current view of the UBC Mining curriculum demands the integration of aspects of environmental and social sciences shaping the future of tertiary engineering education. The solution is developing a curriculum that is focused on key learning objectives that are a reflection of all these external pressures. This paper examines the challenge of curriculum reform and the emergence of learning communities at the Norman B.

    Full Text Available A major challenge in engineering education is retaining student interest in the engineering discipline. Active student involvement in engineering projects is one way of retaining student interest. Such involvement can only be realized if project inception comes entirely from the student. This paper presents a software game, RMU Monopoly, developed as a project requirement for a software engineering course and describes the challenges and gains of implementing such a project. The RMU Monopoly was proposed by three junior software engineering students. The game is a multi-platform software program that allows up to eight players and implements the rules of the Monopoly board game. To ensure agility the game was developed using the spiral software development model. The Software Requirements Specification (SRS document was finalized through an iterative procedure. Standard Unified Modeling Language (UML diagrams were used for product design. A Risk Mitigation, Monitoring, and Management Plan (RMMM was developed to ensure proactive risk management. Gantt chart, weekly progress meetings and weekly scrum meetings were used to track project progress. C# and Sub- Version were used in a client-server architecture to develop the software.

  11. The Case for Distributed Engine Control in Turbo-Shaft Engine Systems

    Science.gov (United States)

    Culley, Dennis E.; Paluszewski, Paul J.; Storey, William; Smith, Bert J.

    2009-01-01

    The turbo-shaft engine is an important propulsion system used to power vehicles on land, sea, and in the air. As the power plant for many high performance helicopters, the characteristics of the engine and control are critical to proper vehicle operation as well as being the main determinant to overall vehicle performance. When applied to vertical flight, important distinctions exist in the turbo-shaft engine control system due to the high degree of dynamic coupling between the engine and airframe and the affect on vehicle handling characteristics. In this study, the impact of engine control system architecture is explored relative to engine performance, weight, reliability, safety, and overall cost. Comparison of the impact of architecture on these metrics is investigated as the control system is modified from a legacy centralized structure to a more distributed configuration. A composite strawman system which is typical of turbo-shaft engines in the 1000 to 2000 hp class is described and used for comparison. The overall benefits of these changes to control system architecture are assessed. The availability of supporting technologies to achieve this evolution is also discussed.

    2002-03-01

    The objective of this project was to isolate and characterize thermophilic bacterial cultures that can be used for the selective removal of nitrogen, sulfur, and/or metals in the biorefining of petroleum. The project was completed on schedule and no major difficulties were encountered. Significant progress was made on multiple topics relevant to the development of a petroleum biorefining process capable of operating at thermophilic temperatures. New cultures capable of selectively cleaving C-N or C-S bonds in molecules relevant to petroleum were obtained, and the genes encoding the enzymes for these unique biochemical reactions were cloned and sequenced. Genetic tools were developed that enable the use of Thermus thermophilus as a host to express any gene of interest, and information was obtained regarding the optimum conditions for the growth of T. thermophilus. The development of a practical biorefining process still requires further research and the future research needs identified in this project include the development of new enzymes and pathways for the selective cleavage of C-N or C-S bonds that have higher specific activities, increased substrate range, and are capable of functioning at thermophilic temperatures. Additionally, there is a need for process engineering research to determine the maximum yield of biomass and cloned gene products that can be obtained in fed-batch cultures using T. thermophilus, and to determine the best configuration for a process employing biocatalysts to treat petroleum.

    Full Text Available In a biomedical engineering lab at Worcester Polytechnic Institute, co-author Dr. Glenn R. Gaudette and his research team are investigating the effects of stem cell therapy on the regeneration of function in damaged cardiac tissue in laboratory rats. Each instance of stem cell experimentation on a rat yields hundreds of data sets that must be carefully captured, documented and securely stored so that the data will be easily accessed and retrieved for papers, reports, further research, and validation of findings, while meeting NIH guidelines for data sharing. After a brief introduction to the bioengineering field and stem cell research, this paper focuses on the experimental workflow and the data generated in one instance of stem cell experimentation; the lab’s data management practices; and how Dr. Gaudette teaches data management to the lab’s incoming graduate students each semester. The co-authors discuss the haphazard manner by which engineering and science students typically learn data management practices, and advocate for the integration of formal data management instruction in higher education STEM curricula. The paper concludes with a discussion of the Frameworks for a Data Management Curriculum developed collaboratively by the co-authors’ institutions -- the University of Massachusetts Medical School and Worcester Polytechnic Institute -- to teach data management best practices to students in the sciences, health sciences, and engineering.

  14. Developing Industrial Cases for Teaching Software Engineering – A Lesson Learned

    Directory of Open Access Journals (Sweden)

    Rozilawati Razali

    2012-12-01

    Full Text Available Software engineers are provided with an enormous choice of technology for improving the quality of software. Being intangible, software products tend to be more intricate to build than any other artifacts. The selection of technology can thus become a critical factor for the success of software development. Software engineers are expected to be well-versed in various technologies to enable them to decide the best one for a particular development project. Sensible decisions however require not only understanding but also active minds, which can be achieved through meaningful learning. Being a discussion-based learning approach that encourages students to exploit knowledge and understanding of the subject matter, the Case Method seems to be a practical teaching and learning option. This method entails developing specific cases that promote exploration and critical thinking. To ensure the developed cases are useful, they should be evaluated. This paper presents a practical methodology for developing as well as evaluating industrial cases for teaching software engineering through the Case Method. It also shares some important lessons learned from the process. These lessons act as a guideline for future case developers to compose useful cases and motivate software engineering instructors to use cases in teaching.

    2010-09-01

    Full Text Available Reverse logistics has gained increasing attention in recent years as a channel for companies to achieve operational excellence. The process involves manipulation of returned materials, or even products, which forms a pivotal role in sustainable development throughout the whole supply chains. To make reverse logistics possible, process re-engineering may need to be carried out. However, the processes involved in reengineering are practically complicated. Objectives, benefits, and applicability of any process re-engineering require a careful and detailed strategic planning. This paper aims to propose an easy-to-follow step-by-step framework for practitioners to perform process re-engineering, to learn and identify the critical issues in each step, and to be successful in applying process re-engineering in order to enhance reverse logistics performance. A learner-centred approach is adopted based on a case study of process re-engineering, which is demonstrated in the paper for explanation.

  13. The role of Project Finance in the viability of infrastructure projects: case of the petroleum and natural gas sector

    International Nuclear Information System (INIS)

    Project finance represents neither recent news nor a panacea in the fields of long term financing. It is not able to solve the chronicle scarcity of resources applied in big projects financing in developing countries. In fact, underdeveloped markets as the Brazilian one offer, at the beginning, almost no chances to the project finance solution. In this case a path full of barriers overcome the solutions that project finance may offer. The process to adapt this instrument to the Brazilian reality presents the following hindrances: a different law framework, capital market underdevelopment; economical instability; political and regulating risks; incapability of the national insurance companies to insure big projects; cultural differences and lack of know-how in this area, and lastly, the out of date tax system.

This paper discusses the current status of simulation, especially dynamic simulation (DS), in engineering projects, which provides means to study process behaviour in both normal operation and during incidents. A case example of solving an engineering problem with DS at the power plant is presented. A model of a once-through evaporator of a coal-fired power plant was developed, and used to analyse thermal behaviour of the evaporator pipes. (orig.)

  15. Safety of engineered structures against blast vibrations: A case study

    Directory of Open Access Journals (Sweden)

    G.R. Tripathy

    2016-04-01

    Full Text Available Blasting used for rock excavation is associated with ground vibrations having potential damage to surrounding structures. The extent of damage produced in a structure depends largely on ground motion characteristics, dynamic characteristics of structure and the type of geological strata on which it is founded. The safety of surrounding structures against blast vibrations is a cause of concern. However, use of a systematic approach to rock blasting helps to complete the excavation safely in time without endangering the safety of surrounding structures. Various steps are commonly adopted at construction sites to ensure safety of engineered structures against blast vibrations, e.g. adopting a suitable safe vibration level, developing site-specific attenuation relation, estimating safe charges for different distances, designing blasting pattern, and monitoring vibrations during actual blasting. The paper describes the details of studies conducted for ensuring safety of an 85 years old masonry dam and green concrete of varying ages during excavation of about 30,000 m3 of hard rock in Maharashtra, India. The studies helped to complete the rock excavation safely in time and the safety of the dam was ensured by monitoring blast vibrations during actual rock excavation.

  16. Prediction of engine casing temperature of fighter aircraft for infrared signature studies

    Science.gov (United States)

    Mahulikar, Shripad P.

    1992-04-01

    Prediction of engine casing temperature of combat aircraft for various operating conditions needs modeling of convective and radiative heat flow from the jet pipe to the casing. Radiation modeling which implies modeling of multiple reflections and scattering is done here by the radiance-irradiance approach. The engine layout is approximated by three co-axial cylinders and axially discretized. The shape factors (which account for the directional dependence of radiation heat flow) for various configurations needed in radiation modeling are analytically obtained by a sequence of shape factor algebra from standard configurations. The resulting non-linear algebraic equations of combined convection and radiation heat flow are solved by an iterative technique to give the engine casing temperatures which may be used for infrared signature studies.

    Choi, Kwang Hee; Lee, Sang Guk; Lee, Byoung Oh [Korea Hydro and Nuclear Power Co., Daejeon (Korea, Republic of)

    2012-05-15

    The effort has been done to effectively improve the maintenance method of emergency diesel generator (EDG) by changing from time based maintenance to condition based maintenance (CBM) in nuclear power plant. Technologies of engine signature analysis to evaluate the diesel generator condition have been applied to CBM for EDG in domestic and foreign nuclear power plants. Engine signature analysis includes both combustion analysis and vibration and ultrasonic analysis. Combustion analysis provides information on the combustion performance of the individual cylinders of the diesel engine. Vibration and ultrasonic analysis provides information on event timing and mechanical condition within the diesel engine. These signatures are collected non-intrusively during a normal loaded engine run. The primary impetus for the use of engine signature analysis has been as part of a program to replace the traditional time based open and inspection maintenance program imposed on plants by the original equipment manufacturers. Condition-based maintenance programs based largely on the use of engine signature analysis have increased the reliability and availability of diesel engine. The results of signature analysis on various cases in EDG of KHNP and overseas nuclear power plants are described in this paper

    This paper presents a retrospective of some of PETROBRAS' main technological advances that contributed for Brazil to reach petroleum production self-sufficiency. The impact of the corporate strategy to invest in training and qualifying human resources in the development of critical technologies for the Company's business is discussed. From the mid-seventies, there has been a significant increase in the effort directed to research and development (R and D) in the Exploration and Production (E and P) segment. Motivated by challenges imposed by ever increasing water depths (WD) and the early production of discovered fields, technological developments accelerated. A few of the topics discussed herein include the competition between wet subsea systems and atmospheric systems, the first floating production units based on semi-submersible drilling platforms and on adapted tankers, the development of wellhead systems, risers and production lines. Beginning in the mid-eighties, PETROBRAS successively broke world records in terms of water depth with its wells and production and off loading facilities. In order to support this leadership, new technologies were developed and adapted, in partnership with vendors and scientific and technological institutions, in the country and abroad. This paper discusses the technologies developed for maintaining the production of mature fields, increasing the production capacity and managing the integrity of installed units, managing great volumes of produced water as a function of mechanisms adopted for the maintenance of reservoir pressure and managing production projects. In conclusion, the main solutions currently in development are described. (author)

    2010-07-01

    Full Text Available As Data Mining for Secure Software Engineering improves software productivity and quality, software engineers are increasingly applying data mining algorithms to various software engineering tasks. However mining software engineering data poses several challenges, requiring various algorithms to effectively mine sequences, graphs and text from such data. Software engineering data includes code bases, execution traces, historical code changes,mailing lists and bug data bases. They contains a wealth of information about a projects-status, progress and evolution. Using well established data mining techniques, practitioners and researchers can explore the potential of this valuable data in order to better manage their projects and do produce higher-quality software systems that are delivered on time and with in budget. Data mining can be used in gathering and extracting latent security requirements, extracting algorithms and business rules from code, mining legacy applications for requirements and business rules for new projects etc. Mining algorithms for software engineering falls into four main categories: Frequent pattern mining – finding commonly occurring patterns; Pattern matching – finding data instances for given patterns; Clustering – grouping data into clusters and Classification – predicting labels of data based on already labeled data. In this paper, we will discuss the overview of strategies for data mining for secure software engineering, with the implementation of a case study of text mining for source code management tool.

  10. Relationships, variety & synergy: the vital ingredients for scholarship in engineering education? A case study

    Science.gov (United States)

    Clark, Robin; Andrews, Jane

    2014-11-01

    This paper begins with the argument that within modern-day society, engineering has shifted from being the scientific and technical mainstay of industrial, and more recently digital change to become the most vital driver of future advancement. In order to meet the inevitable challenges resulting from this role, the nature of engineering education is constantly evolving and as such engineering education has to change. The paper argues that what is needed is a fresh approach to engineering education - one that is sufficiently flexible so as to capture the fast-changing needs of engineering education as a discipline, whilst being pedagogically suitable for use with a range of engineering epistemologies. It provides an overview of a case study in which a new approach to engineering education has been developed and evaluated. The approach, which is based on the concept of scholarship, is described in detail. This is followed by a discussion of how the approach has been put into practice and evaluated. The paper concludes by arguing that within today's market-driven university world, the need for effective learning and teaching practice, based in good scholarship, is fundamental to student success.

  15. Multiple case studies of STEM teachers' orientations to science teaching through engineering design

    Science.gov (United States)

    Rupp, Madeline

    The following master's thesis is composed of two manuscripts describing STEM teachers' orientations to science teaching through engineering within the context of the Science Learning through Engineering Design (SLED) partnership. The framework guiding both studies was science teaching orientations, a component of pedagogical content knowledge. Data were collected via semi-structured interviews, multi-day classroom observations, pre- and post-observation interviews, implementation plans, and written reflections. Data sources were analyzed to generate two orientations to science teaching through engineering design for each participant. The first manuscript illustrates a single case study conducted with a sixth grade STEM teacher. Results of this study revealed a detailed picture of the teacher's goals, practices, assessments, and general views when teaching science through engineering design. Common themes across the teacher's instruction were used to characterize her orientations to science teaching through engineering design. Overall, the teacher's orientations showed a shift in her practice from didactic to student-centered methods of teaching as a result of integrating engineering design-based curriculum. The second manuscript describes a comparative case study of two sixth grade SLED participants. Results of this study revealed more complex and diverse relationships between the teachers' orientations to teaching science through engineering design and their instruction. Participants' orientations served as filters for instruction, guided by their divergent purposes for science teaching. Furthermore, their orientations and resulting implementation were developed from knowledge gained in teacher education, implying that teacher educators and researchers can use this framework to learn more about how teachers' knowledge is used to integrate engineering and science practices in the K-12 classroom.

  20. Petroleum crisis: technological answers

    International Nuclear Information System (INIS)

    From 1993 until 2020 the world would have consume about 140 milliards tonnes of petroleum products, exactly the actual reserves, it's worth thinking over. This evolution will need to use more and more Middle-East petroleum and to reduce production prices for other ones. It is necessary to go on making technological efforts in this way to diversify provisioning. Seismic detection in three directions (3D seismic) which increase lucks of success in drilling, horizontal drilling which improve productivity, offshore petroleum production which takes a part of 30% of world production today, natural gas expansion which reserves are as important as petroleum ones but not so much exploited, all that things are as many ways to assure perenniality of petroleum production

  1. Immunoassay for petroleum hydrocarbons

    International Nuclear Information System (INIS)

    Petroleum hydrocarbon contamination of soil and ground water has become a serious environmental problem. Since the 1940s, it has been a common practice to bury fuel tanks underground to guard against fire and explosions. The leakage of petroleum fuel from these aging tanks creates a long term threat to human health. In order to location and identify these sources of contamination, an on-site screening test is very desirable. A simple, inexpensive petroleum hydrocarbon immunoassay has been developed for this purpose. The EnviroGard Petroleum Hydrocarbon test kit is designed for qualitative or semiquantitative analysis of petroleum hydrocarbon fuel in soil and ground water. The assay can be easily used on-site and takes 15 minutes to perform. Following a 2 minute methanol extraction, the test is performed in polystyrene tubes and can detect gasoline, diesel fuel, kerosene, home heating oil and other major fuels at ppm levels in soil and sub-ppm levels in water samples

  4. Case-based Reasoning for Automotive Engine Performance Tune-up

    International Nuclear Information System (INIS)

    The automotive engine performance tune-up is greatly affected by the calibration of its electronic control unit (ECU). The ECU calibration is traditionally done by trial-and-error method. This traditional method consumes a large amount of time and money because of a large number of dynamometer tests. To resolve this problem, case based reasoning (CBR) is employed, so that an existing and effective ECU setup can be adapted to fit another similar class of engines. The adaptation procedure is done through a more sophisticated step called case-based adaptation (CBA)[1, 2]. CBA is an effective knowledge management tool, which can interactively learn the expert adaptation knowledge. The paper briefly reviews the methodologies of CBR and CBA. Then the application to ECU calibration is described via a case study. With CBR and CBA, the efficiency of calibrating an ECU can be enhanced. A prototype system has also been developed to verify the usefulness of CBR in ECU calibration.

  6. Multiple case study analysis of young women's experiences in high school engineering

    Science.gov (United States)

    Pollock, Meagan C.

    richly describe the diversity of experiences. A multiple case study analysis, this study answers the question: How do gender, class, race, and other components of intersectionality, influence high school females' experiences in engineering? Nine young women taking a high school engineering course in a suburban high school in Central Texas during the school year 2011-2012 volunteered to participate. The students were observed in their engineering classes for half of the spring 2012 semester, with bi-weekly interviews with the students, monthly interviews with the teacher, and a single interview with a parent of each volunteer. The nine rich case studies provide us with new stories that help prevent us from narrowing the experiences of women to a single incomplete stereotype, because these young women vary across race, socioeconomic backgrounds, and sexual orientation. Although each story is unique, there are commonalities among their experiences, including family, influence, classroom environment, biases, and beliefs. By drawing from their collective experiences in high school engineering, the findings direct us toward recommendations for educators, parents, engineering curriculum developers, designers of teacher professional development, and future research to improve equity and access for every student in engineering.

    2012-10-15

    The purpose of this report is to summarise the findings of the scientific and technical work undertaken by CONCAWE to assess the feasibility and potential benefit of characterising petroleum UVCB substances (Substances of Unknown or Variable Composition, Complex reaction products or Biological Materials) beyond the recommendations issued by CONCAWE for the substance identification of petroleum substances under REACH. REACH is the European Community Regulation on chemicals and their safe use (EC 1907/2006). It deals with the Registration, Evaluation, Authorisation and Restriction of Chemical substances. The report is based on Member Company experience of the chemical analysis of petroleum UVCB substances, including analysis in support of REACH registrations undertaken in 2010. This report is structured into four main sections, namely: Section 1 which provides an introduction to the subject of petroleum UVCB substance identification including the purpose of the report, regulatory requirements, the nature of petroleum UVCB substances, and CONCAWE's guidance to Member Companies and other potential registrants. Section 2 provides a description of the capabilities of each of the analytical techniques described in the REACH Regulation. This section also includes details on the type of analytical information obtained by each technique and an evaluation of what each technique can provide for the characterisation of petroleum UVCB substances. Section 3 provides a series of case studies for six petroleum substance categories (low boiling point naphthas, kerosene, heavy fuel oils, other lubricant base oils, residual aromatic extracts and bitumens) to illustrate the value of the information derived from each analytical procedure, and provide an explanation for why some techniques are not scientifically necessary. Section 4 provides a summary of the conclusions reached from the technical investigations undertaken by CONCAWE Member Companies, and summarising the

    Institute of Scientific and Technical Information of China (English)

    LIU Ying-chao; ZANG Chao-ping

    2011-01-01

    Vibration mode shape description of an aero-engine casing structure using Zernike moment descriptor (ZMD) was introduced in this paper. The mode shapes of the aero-engine casing structure can be decomposed as a linear combination of a series of Zernike polynomials, with the feature of each Zernike polynomial reflecting a part of characteristic of mode shapes, based on Zernike moment transformation. Meanwhile, the reconstruction of mode shapes with ZMD was explored and its ability to filtering the noise contaminated in the mode shapes was studied. Simulation of the aero-engine casing structure indicated the advantage of this method to depict the mode shapes of a symmetric structure. Results demonstrate that the Zernike moment description of the mode shapes can effectively describe the double modes in the symmetric structure and also has the ability to remove or significantly reduce the influence of noise in the mode shapes. Such feature shows great practical value for further research on the correlation, model updating and model validation of the symmetric structure's finite element model.

    2005-07-01

    Oil companies rarely carry out themselves the important works planned in the framework of their investments or of the exploitation of their facilities. In most cases, they act as prime contractor and generate a huge market of equipments, services and engineering needs in which many companies of various size are involved and make the overall para-petroleum industry. The French position on this market was asserted very early thanks to the continuation of ambitious R and D programs, very often carried out in the framework of the CEP and M and of the COPREP, which have permitted to build and maintain a solid technological knowledge. In this context, the lack of regular statistical data about the French para-petroleum industry has led, since 1978, the group of para-petroleum and para-gas companies, the CEP and M and the former COPREP (now the Committee of petroleum and marine studies - CEP and M), and the French institute of petroleum (IFP), to launch an annual inquiry at the national scale. This document makes a brief overview of the international context of the petroleum industry and then presents the last results of the 2004 inquiry about the French para-petroleum industry. Some data are foreseen for 2005, based on the estimations supplied by the companies themselves. (J.S.)

  11. Exposure to magnetic fields of railway engine drivers: A case study in Italy

    International Nuclear Information System (INIS)

    A case study of exposure assessment of railway workers to static and extremely low frequency (ELF) magnetic fields is presented. A measurement campaign was conducted in aboard Italian main line trains. All measurements were performed on board during regular service (two engine drivers were simultaneously present), in all places potentially accessible to personnel, considering routes ranging from a few tens of kilometres to hundreds of kilometres. The measurement protocol was mostly based on broadband metres and personal metres were employed to assess individual exposure. Surveys on static and ELF magnetic fields were performed for seven different models of engine or electrified train. Traction motors were fed by alternating current (AC) current, except for two engines, where AC current fed only auxiliary services. The final result is that the average exposure to static magnetic field was a little higher than the background geomagnetic field; occasionally in few areas it could reach levels of the order of milli-tesla. The average exposure to ELF magnetic fields was in the order of 1-2 μT, with higher levels (few micro-tesla) only for one engine; occasionally in hot spots, close to wiring or specific equipment, the field values could reach several tens of micro-tesla.

  12. Associated petroleum gas in Russia: reasons for non-utilization

    Energy Technology Data Exchange (ETDEWEB)

    2010-10-22

    This report studies the factors hindering increased utilization of associated petroleum gas (APG) in Russia. The issue of flaring versus utilization is studied from a Technology Innovation System (TIS) perspective, seeing the non-utilization issue as a problem of technology diffusion. There are many technological options available for APG utilization, but a main blocking mechanism in the Russian case is the Gazprom monopoly on gas transportation via their pipelines. A commonly discussed solution is policy to ensure third party access, but this study finds that this solution holds little potential, as its ramifications are too extensive and unacceptable to the key actor Gazprom. More promising solutions may be found in small, emerging engineering companies. (Author)

  14. Engineered Barrier Systems (EBS) in the safety case: the role of modelling workshop proceedings

    International Nuclear Information System (INIS)

    In the deep disposal of radioactive waste, the presence of several barriers serving complementary safety functions enhances confidence that the waste will be isolated and contained to protect human health and the environment. The barriers include the natural geological barrier and the engineered barrier system (EBS). The EBS itself may comprise a variety of sub-systems or components, such as the waste form, container, buffer, backfill, seals and plugs. The Integration Group for the Safety Case (IGSC) of the Nuclear Energy Agency (NEA) is co-sponsoring a series of workshops with the European Commission to develop greater understanding of how to achieve the necessary integration for the successful design, testing, modelling and performance assessment of engineered barrier systems (EBS) for deep underground disposal of radioactive waste. These proceedings include the main findings and presented papers from the third NEA-EC workshop on engineered barrier systems, which focused on the role of EBS modelling in the safety case for deep disposal. Some national programmes are placing increased emphasis on EBS and, as implementation of underground repositories approaches, more realistic assessments of EBS performance are needed. The workshop examined the modelling tools currently available and identified complex areas of assessment in which further dialogue is needed. (author)

    2015-09-01

    Full Text Available This paper presents a case study examining 3rd, 4th and 5th graders’ design fixation and cooperative learning in an engineering design project. A mixed methods instrument, the Cooperative Learning Observation Protocol (CLOP, was adapted to record frequency and class observation on cooperative learning engagement through detailed field notes. Students’ design journals and reflections were also analyzed for an inductive qualitative analysis. The findings indicate three major themes of design fixation: 1 fixation on common features of things; 2 fixation on popular teenage culture; 3 fixation on the first design idea. In the cooperative learning process of elementary engineering design project, although pupils had demonstrated some abilities to solve concrete problems in a logical fashion, the participants encountered a number of obstacles in the group. Dominance, social loafing, and other problems occurring in the group process might have offset certain benefits of cooperative learning. Implications of the findings are also discussed.

    Vielma, Karina I.

    Research points to the many obstacles that first-generation, Latina students face when attempting to enter fields in science, technology, engineering, and mathematics, STEM. This qualitative, case study examined the personal and educational experiences of first-generation Latina women who successfully navigated the STEM educational pipeline earning bachelor's, master's, and doctoral degrees in various fields of engineering. Three research questions guided the study: (1) How does a first-generation Latina engineer and scientist describe her life experiences as she became interested in STEM? (2) How does she describe her educational experiences as she navigated the educational pipeline in the physics, mathematics, and/or engineering field(s)? (3) How did she respond to challenges, obstacles and microaggressions, if any, while navigating the STEM educational pipeline? The study was designed using a combination of Critical Race Theory frameworks---Chicana feminist theory and racial microaggressions. Through a life history case study approach, the women shared their stories of success. With the participants' help, influential persons in their educational paths were identified and interviewed. Data were analyzed using crystallization and thematic results indicated that all women in this study identified their parents as planting the seed of interest through the introduction of mathematics. The women unknowingly prepared to enter the STEM fields by taking math and science coursework. They were guided to apply to STEM universities and academic programs by others who knew about their interest in math and science including teachers, counselors, and level-up peers---students close in age who were just a step more advanced in the educational pipeline. The women also drew from previous familial struggles to guide their perseverance and motivation toward educational degree completion. The lives of the women where complex and intersected with various forms of racism including

    Crude oil refining is an industrial activity known as very pollutant, as all other activities of the petroleum industry, regarding either the volume or the concentration of the resides involved, thus generating emissions, effluents and solid wastes. The aim of the present work is to study solid waste management of a certain petroleum refinery, located in Rio de Janeiro. On the solid wastes management of that refinery, the following aspects were considered: origin and period of generation, conditioning, storage, transportation, treatment and final disposal. After listing all the resides and through analysis of the industrial wastes (norms, terms, inventory), the industrial process and office routines were then analyzed. The solid wastes were divided in two categories: industrial and administrative wastes. As far as destination is concerned, resides classified as Class I are either co-processed or incinerated, while Class II and Class III wastes, when not recycled, are sent to industrial or sanitary landfill. Finally, after analyzing the wastes management of the refinery, it has been proposed a plan of achievements in order to enhance the environmental goal of the refinery. (author)

    The fan case in a jet engine is a heavy structure because of its size and because of the requirement that it contain a blade released during engine operation. Composite materials offer the potential for reducing the weight of the case. Efficient design, test, and analysis methods are needed to efficiently evaluate the large number of potential composite materials and design concepts. The type of damage expected in a composite case under blade-out conditions was evaluated using a subscale test in which a glass/epoxy composite half-ring target was impacted with a wedge-shaped titanium projectile. Fiber shearing occurred near points of contact between the projectile and target. Delamination and tearing occurred on a larger scale. These damage modes were reproduced in a simpler test in which flat glass/epoxy composites were impacted with a blunt cylindrical projectile. A surface layer of ceramic eliminated fiber shear fracture but did not reduce delamination. Tests on 3D woven carbon/epoxy composites indicated that transverse reinforcement is effective in reducing delamination. A 91 cm (36 in.) diameter full-ring sub-component was proposed for larger scale testing of these and other composite concepts. Explicit, transient, finite element analyses indicated that a full-ring test is needed to simulate complete impact dynamics, but simpler tests using smaller ring sections are adequate when evaluation of initial impact damage is the primary concern.

    There is no doubt that Search Engines are playing a great role in Internet usage. But all the top search engines Google, Yahoo and Bing are having a critical flaw called "Openness of a Search Engine". An Internet user should be allowed to get the search results only when requested through Search engine's web page but the user must not be allowed to get the search results when requested through any web page that does not belong to the Search Engine. Only results of a search engine should be available to the Internet user but not the Search Engine. This paper explains the critical flaw called "Openness of Search Engine" with a case study on top 3 search engines 'Google', 'Yahoo' and 'Bing'. This paper conducts an attack based test using J2EE framework and proves that 'Google' passed the test and it strongly protects its Critical Search System, where 'Yahoo' and 'Bing' are failed to protect their Search Engines. But previously 'Google' also had other high severity issues with the Openness of search engine; this ...

  13. Engineered Barrier Systems (EBS) in the safety case: design confirmation and demonstration

    International Nuclear Information System (INIS)

    The presence of several barriers serving complementary safety functions enhances confidence that radioactive waste placed in deep geological repositories will be adequately isolated and contained to protect human health and the environment. The barriers include the natural geological barrier and the engineered barrier system (EBS). The EBS itself may comprise a variety of sub-systems or components, such as the waste form, container, buffer, backfill, seals and plugs. Given the importance of this subject, the Integration Group for the Safety Case (IGSC) of the OECD Nuclear Energy Agency (NEA) sponsored a series of workshops with the European Commission to develop greater understanding of how to achieve the necessary integration for the successful design, testing, modelling and performance assessment of EBS for deep underground disposal of radioactive waste. These proceedings present the main findings from, and the papers delivered at, the fourth NEA-EC workshop on EBS, which took place in Tokyo, Japan, in September 2006. This final workshop of the series focused on strategies and methods to demonstrate that EBS designs will fulfill the relevant requirements for long-term safety, engineering feasibility and quality assurance. The workshop highlighted that large-scale experiments have confirmed the feasibility of techniques for manufacturing and installing engineered components in disposal systems and have also provided valuable lessons to improve designs and refine practical aspects to construct and implement EBS.

    Full Text Available The environment in which university institutions develop their activities is showing some weaknesses in the training provided to their graduates. One of the notable weaknesses is the failure to match the competencies empowered in students by universities and the competencies demanded by business organisations. In view of this situation, this article endeavours to analyse the state of the art in our country, thereby using the case of engineers as an example. Therefore, the opinions stated by a group of employers in a questionnaire are analysed. The results obtained show that, in the analysed case, the educational offer of universities, measured through various competencies, does not comply with business demands. Thus, a deficit situation is detected in all the analysed competencies, which have been grouped together into four categories: Those contained in the Major of Study, Social Skills, Methodological Skills and Participation Competencies. This situation should cause universities to restate the educational offer that they are providing.

    International Nuclear Information System (INIS)

    'Full-text:' The VEGA European small launcher of new generation is made of four stages of which the first three are solid propellant engines of advanced technology. The long experience reached in the solid propellant Field through Ariane 3, 4 and 5 programme, identified AVIO how the manufacturer of the 1st, 2nd and 3rd stage of the launcher. With the aim of minimizing launcher cost, a new technology using a low weight motor case made of carbon fiber has been developed. Other than process of fabrication also process of control are involved in the development of the new technology and, in considering the large size of the engines, the latter fall heavily on the manufacturing time and cost. In view of the reducing the recurrent cost of the launcher, AVIO is particularly interested in new technologies having the potentiality to reduce control costs. Among Non-Destructive Tests, the X-ray inspection is irreplaceable for its effectiveness, therefore improvements in X-ray imaging techniques aimed at decreasing control cost without any performance reduction, is a challenge that AVIO intends to pursue. From this point of view Digital Radiography offers good opportunity to which AVIO is looking to define the applicability to the case of interest. This paper shows the status of art and summarizes the results obtained through tests performed in collaboration with the main suppliers of digital devices working in industrial high energy X-ray NonDestructive Testing Field.

  3. Creating a strategic plan for configuration management using computer aided software engineering (CASE) tools

    International Nuclear Information System (INIS)

    This paper provides guidance in the definition, documentation, measurement, enhancement of processes, and validation of a strategic plan for configuration management (CM). The approach and methodology used in establishing a strategic plan is the same for any enterprise, including the Department of Energy (DOE), commercial nuclear plants, the Department of Defense (DOD), or large industrial complexes. The principles and techniques presented are used world wide by some of the largest corporations. The authors used industry knowledge and the areas of their current employment to illustrate and provide examples. Developing a strategic configuration and information management plan for DOE Idaho Field Office (DOE-ID) facilities is discussed in this paper. A good knowledge of CM principles is the key to successful strategic planning. This paper will describe and define CM elements, and discuss how CM integrates the facility's physical configuration, design basis, and documentation. The strategic plan does not need the support of a computer aided software engineering (CASE) tool. However, the use of the CASE tool provides a methodology for consistency in approach, graphics, and database capability combined to form an encyclopedia and a method of presentation that is easily understood and aids the process of reengineering. CASE tools have much more capability than those stated above. Some examples are supporting a joint application development group (JAD) to prepare a software functional specification document and, if necessary, provide the capability to automatically generate software application code. This paper briefly discusses characteristics and capabilities of two CASE tools that use different methodologies to generate similar deliverables

    International Nuclear Information System (INIS)

    The influence of petroleum market disturbances on price increases was discussed with particular reference to Hurricane Katrina and the loss of refinery production and damage to oil infrastructure in the United States. The supply of petroleum products in Canada will be very tight heading into the winter of 2006, despite the fact that Canadian refineries are operating at full capacity to ensure an adequate supply of gasoline and diesel fuel for consumers. In addition to refinery production, petroleum supplies are also determined by the adequacy of inventories and the efficiency of the infrastructure in place to deliver products to where they are needed. The lack of spare capacity has reduced the flexibility of the North American refining system to respond to further disruptions. Refiners were asked to provide information on 4 areas of their operations in order for Natural Resources Canada to analyze the short-term outlook for petroleum products markets. The 4 areas included refinery utilization rates and capability to increase production; any planned refinery turnaround that would affect petroleum product supplies; inventory levels compared to levels in previous years; and, any logistical problems that could affect product distribution. A graph depicting the relationship between Canadian production of gasoline and domestic sales clearly illustrated the seasonal nature of gasoline consumption and that production in Canada is much higher than consumption. Canada exports large volumes of gasoline, primarily to the United States eastern seabord from refineries in Atlantic Canada. The trend is similar for diesel fuel. Demand for both gasoline and diesel is expected to continue to grow in 2005 as high prices have had a limited impact on demand growth. In general, the Ontario/Quebec region is short of gasoline and must import gasoline during the summer months to cover the shortfall. It was noted that motorists and homeowners who heat with oil will bear the burden of higher

    The Computer Aided System Engineering and Analysis (CASE/A) Version 5.0 Programmer's Manual provides the programmer and user with information regarding the internal structure of the CASE/A 5.0 software system. CASE/A 5.0 is a trade study tool that provides modeling/simulation capabilities for analyzing environmental control and life support systems and active thermal control systems. CASE/A has been successfully used in studies such as the evaluation of carbon dioxide removal in the space station. CASE/A modeling provides a graphical and command-driven interface for the user. This interface allows the user to construct a model by placing equipment components in a graphical layout of the system hardware, then connect the components via flow streams and define their operating parameters. Once the equipment is placed, the simulation time and other control parameters can be set to run the simulation based on the model constructed. After completion of the simulation, graphical plots or text files can be obtained for evaluation of the simulation results over time. Additionally, users have the capability to control the simulation and extract information at various times in the simulation (e.g., control equipment operating parameters over the simulation time or extract plot data) by using "User Operations (OPS) Code." This OPS code is written in FORTRAN with a canned set of utility subroutines for performing common tasks. CASE/A version 5.0 software runs under the VAX VMS(Trademark) environment. It utilizes the Tektronics 4014(Trademark) graphics display system and the VTIOO(Trademark) text manipulation/display system.

  12. Project-based learning in a high school engineering program: A case study

    Science.gov (United States)

    France, Todd

    Generating greater student interest in science, technology, engineering, and mathematics (STEM) has been a major topic of discussion among educators, policymakers, and researchers in recent years, as increasing the number of graduates in these fields is widely considered a necessary step for sustaining the progress of today's society. Fostering this interest must occur before students reach college, and substantial efforts have been made to engage students at K-12 levels in STEM-focused learning. Attempts to involve students in engineering, a vital and growing profession, yet one in which students often have little experience, have frequently emphasized the design and construction of physical products, a practice supported by project-based learning. This thesis examines the environment of an engineering high school course that employed the project-based model. The course is part of a dedicated curricular program which aims to provide students with positive experiences in engineering-related activities while also preparing them for the rigors of college. A case study was conducted to provide insight into the benefits and drawbacks of the learning model. The study's outcomes are intended to provide guidance to educators participating in the design and/or facilitation of project-based activities, particularly those involved with engineering education. The research was performed using a qualitative approach. Long-term engagement with course participants was deemed critical to gaining a comprehensive understanding of the interactions and events that transpired on a daily basis. Nine educators involved with the program were interviewed, as were nineteen of the course's thirty-nine students. A wealth of other relevant data -- including surveys, field notes, and evaluations of student work -- was compiled for analysis as well. The study findings suggest that experiences in problem solving and teamwork were the central benefits of the course. Limitations existed due to a

  17. Preferential Petroleum Migration Pathways in Eastern Pearl River Mouth Basin,Offshore South China Sea

    Institute of Scientific and Technical Information of China (English)

    Yu Jianning; Zou Huayao; Gong Zaisheng

    2009-01-01

    Secondary petroleum migration in the eastern Pearl River Mouth basin was modeled using the three-dimensional PATHWAYSTM model,which assumes that the positions of petroleum migration pathways are controlled by the morphology of the sealing surfaces.The modeling results have accurately predicted the petroleum occurrences.Most commercial petroleum accumulations are along the predicted preferential petroleum migration pathways (PPMP),and most large fields (petroleum reserves greater than 1×108 t) have more than one preferential petroleum migration pathways to convey petroleum to the traps.The lateral migration distance for oil in the LH11-1 field,the largest oilfield so far discovered in the Pearl River Mouth basin,was more than 80 km.The case study suggests that in lacustrine fault basins,petroleum can migrate over a long distance to form large oilfields without driving force from groundwater flow.The focusing of petroleum originating from a large area of the generative kitchens into restricted channels seems to be essential not only for long-range petroleum migration in hydrostatic conditions,but also for the formation of large oil or gas fields.The strong porosity and permeability heterogeneities of the carrier beds and the relatively high prediction accuracy by a model that does not take into consideration of the effect of heterogeneity suggest that the positions of petroleum migration pathways in heterogeneous carrier beds with relatively large dipping angles are determined primarily by the morphology of the sealing surfaces at regional scales.

    2014-01-01

    Full Text Available Support looseness fault is a type of common fault in aeroengine. Serious looseness fault would emerge under larger unbalanced force, which would cause excessive vibration and even lead to rubbing fault, so it is important to analyze and recognize looseness fault effectively. In this paper, based on certain type turbofan engine structural features, a rotor-support-casing whole model for certain type turbofan aeroengine is established. The rotor and casing systems are modeled by means of the finite element beam method; the support systems are modeled by lumped-mass model; the support looseness fault model is also introduced. The coupled system response is obtained by numerical integral method. In this paper, based on the casing acceleration signals, the impact characteristics of symmetrical stiffness and asymmetric stiffness models are analyzed, finding that the looseness fault would lead to the longitudinal asymmetrical characteristics of acceleration time domain wave and the multiple frequency characteristics, which is consistent with the real trial running vibration signals. Asymmetric stiffness looseness model is verified to be fit for aeroengine looseness fault model.

Association models are defined as the models of SAFT/CPA family (and others) which incorporate hydrogen bonding and other complex interactions. Such...... association models have been, especially over the last 20 years, proved to be very successful in predicting many thermodynamic properties in the oil & gas industry. They have not so far replaced cubic equations of state, but the results obtained by using these models are very impressive in many cases, e.......g., for gas hydrate related systems, CO2/H2S mixtures, water/hydrocarbons and others. This review highlights both the major advantages of these association models and some of their limitations, which we believe should be discussed in the future....

    International Nuclear Information System (INIS)

    This paper uses an ARMAX-ARCH model to estimate the conditional expected returns of petroleum futures prices under time-varying risk. Empirical results suggest that macroeconomic risk factors have significant forecast power in petroleum futures markets. The conditional expected returns for petroleum futures prices are quite large. Results from a small forecasting experiment indicate that the out-of-sample forecasts from an ARMAX-ARCH model generally outperform a random walk for all forecast horizons. Regression-based tests for market timing indicate that the model captures both the correct sign and the correct magnitude. Net trading profits are positive in all cases

  2. Women in engineering: A case study in preparation, persistence, and response

    Science.gov (United States)

    Winkelman, Colin Kim

    This qualitative case study examined women students' perceptions of major influences on their successful completion of a Bachelor of Science degree in nine different disciplines of engineering. In-depth interviews were conducted with 13 female engineering students at an Institute of Technology over the period of a school year. The conceptual framework of analysis linked theoretical principles to categories of analysis that were correlated to three outcomes: preparation, persistence, and response. Emergent properties generated from in-depth interviews were then linked to the categories of preparation, interest-congruence, gender identity, social acceptance, campus culture, learning styles, classroom and faculty relations, sense of accomplishment, tokenism, career expectations, and family planning. Data collection was triangulated through individual interviews and a focus group with the 13 respondents and comparisons to quantitative research outcomes concerning self-confidence, persistence, satisfaction, and career expectations. The findings generally support the theories and propositions outlined in the conceptual framework constructed for this study. The most important of these findings include the impact of social conditioning on gender and academic preparation, the correlation of peer group relations to persistence, and the future expectations female students derive from their experiences over their 4 years of study. The data strongly suggest that traditional gender roles are a social conditioning process that can be overcome, permitting women to succeed in nontraditional academic career fields. Further research could build on these findings to explore social changes in attitudes about women engineers in the workplace, comparisons between men and women's persistence styles, and the importance of science and mathematics intervention programs for girls.

    Full Text Available In this study, the education method which is different from traditional Chinese education methods for its accentuation of practical training is proposed. Compared with traditional engineering education methods, engineering-oriented practical training methodology is student-centered, contains various educational activities, requires interdisciplinary skills, values teamwork and have more objective evaluation methods. Based on the educational case of anti-skid control of railway train, a semi-physical simulation platform is introduced with details in design philosophy, system structure, operator interface and training process. The intention of creating the platform is to provide the students who use it with more hands-on experience since one of the key factors in transfer of learning is the diversion of practice. Based on the knowledge transfer theory, we encourage our students to do their work more independently and freely and the corresponding scores of their performance prove that the students who are better-rounded tend to perform well in the training courses we offered while those only with straight a scores may not outperform their classmates. Thus, the results indicate that this mode is effective in education and instructive to the reform of technological college education.

  7. Multi-model approach to petroleum resource appraisal using analytic methodologies for probabilistic systems

    Energy Technology Data Exchange (ETDEWEB)

    Crovelli, R.A.

    1988-11-01

    The geologic appraisal model that is selected for a petroleum resource assessment depends upon purpose of the assessment, basic geologic assumptions of the area, type of available data, time available before deadlines, available human and financial resources, available computer facilities, and, most importantly, the available quantitative methodology with corresponding computer software and any new quantitative methodology that would have to be developed. Therefore, different resource assessment projects usually require different geologic models. Also, more than one geologic model might be needed in a single project for assessing different regions of the study or for cross-checking resource estimates of the area. Some geologic analyses used in the past for petroleum resource appraisal involved play analysis. The corresponding quantitative methodologies of these analyses usually consisted of Monte Carlo simulation techniques. A probabilistic system of petroleum resource appraisal for play analysis has been designed to meet the following requirements: (1) includes a variety of geologic models, (2) uses an analytic methodology instead of Monte Carlo simulation, (3) possesses the capacity to aggregate estimates from many areas that have been assessed by different geologic models, and (4) runs quickly on a microcomputer. Geologic models consist of four basic types: reservoir engineering, volumetric yield, field size, and direct assessment. Several case histories and present studies by the US Geological Survey are discussed.

    Oil prices are increasing while current explanations for this phenomenon are no longer satisfactory. The cheap petroleum era is ending and this problem can seriously convulse our lifestyles. Transports, agriculture, plastics, clothes, medicines: petroleum is everywhere. This is why the rise of hydrocarbons price will not be a simple economic shock but the end of the world like the one we know. However, it is still possible to postpone this event to a later date and to limit its effects by the implementation of a new oil sobriety era. This implies to already organize the decay of materials and energy consumption, together with keeping solidarity, democracy and peace up. In this condition only the transition will be less painful. (J.S.)

  9. Geopolitics of petroleum

    International Nuclear Information System (INIS)

    The unexpected rise of oil prices since 2004 reveals some structural weaknesses of oil markets in front of the evolution of demand. It conceals considerable stakes, more political than strategic, like the securing of oil and petroleum product supplies of big consumers like the USA and China. This demand generates deep changes in the relations between the different actors, from Venezuela to Russia, from the Caspian sea to the Arab-Persian gulf, from the Mediterranean sea to the gulf of Guinea. Terrorists, who try to destabilize markets using threats on petroleum infrastructures, add-up a risk dimension to the uncertainties. The author proposes a world tour of the main production areas, along the 'oil roads' where the main strategic manoeuvres take place. He shades light on the main power stakes: pressure, tensions, threats and deals, alliances, ruptures and potential conflicts. The complex and multiple motivations are explained. (J.S.)

    2015-08-01

    Full Text Available High-sensitivity monitoring solutions are crucial for early warning systems of earth structures. In this paper, we discuss the design and implementation of such systems for natural and engineered slopes using two case studies. At the Gradenbach Observatory, one key element of the monitoring system is a large fiber optic strain rosette embedded in the slope. We demonstrate that the strain rosette can depict landslide deformations much earlier than geodetic sensors like GPS or total stations and is therefore well suitable for an early warning system. In a second application we report the construction of a reinforced earth structure using geogrids. A distributed fiber optic measurement system was installed to measure the current operating grade of the geogrids within the earth structure. About 2 km of Brillouin sensing cables were installed in the project area. It is demonstrated that the developed monitoring system is well suited for assessing the current state of health of reinforced earth structures.

    2016-01-01

    We present recent developments in lattice Boltzmann modeling for multi-component flows, implemented on the platform of a general purpose, arbitrary geometry solver PowerFLOW. Presented benchmark cases demonstrate the method's accuracy and robustness necessary for handling real world engineering applications at practical resolution and computational cost. The key requirements for such approach are that the relevant physical properties and flow characteristics do not strongly depend on numerics. In particular, the strength of surface tension obtained using our new approach is independent of viscosity and resolution, while the spurious currents are significantly suppressed. Using a much improved surface wetting model, undesirable numerical artifacts including thin film and artificial droplet movement on inclined wall are significantly reduced.

    Design and analysis of Environmental Control and Life Support Systems (ECLSS) and Active Thermal Control Systems (ATCS) for spacecraft missions requires powerful software that is flexible and responsive to the demands of particular projects. CASE/A is an interactive trade study and analysis tool designed to increase productivity during all phases of systems engineering. The graphics-based command-driven package provides a user-friendly environment in which the engineer can analyze the performance and interface characteristics of an ECLS/ATC system. The package is useful during all phases of a spacecraft design program, from initial conceptual design trade studies to the actual flight, including pre-flight prediction and in-flight anomaly analysis. The CASE/A program consists of three fundamental parts: 1) the schematic management system, 2) the database management system, and 3) the simulation control and execution system. The schematic management system allows the user to graphically construct a system model by arranging icons representing system components and connecting the components with physical fluid streams. Version 4.1 contains 51 fully coded and documented default component routines. New components can be added by the user through the "blackbox" component option. The database management system supports the storage and manipulation of component data, output data, and solution control data through interactive edit screens. The simulation control and execution system initiates and controls the iterative solution process, displaying time status and any necessary diagnostic messages. In addition to these primary functions, the program provides three other important functional areas: 1) model output management, 2) system utility commands, and 3) user operations logic capacity. The model output management system provides tabular and graphical output capability. Complete fluid constituent mass fraction and properties data (mass flow, pressure, temperature

  10. Climate change issue table : petroleum downstream sector industry foundation paper

    International Nuclear Information System (INIS)

    An analysis of the impact of the Kyoto Protocol on the Canadian downstream petroleum industry is presented. The downstream sector includes petroleum refining, plus all activities regarding distribution, marketing and retailing of petroleum products. In 1990, the carbon dioxide (CO2) emissions resulting from the production and consumption of petroleum products were about 207 megatons which is about 45 per cent of total Canadian CO2 emissions. This report includes the analysis of the Base Case and the Kyoto Case. The Base Case is premised on the implementation of fuel sulphur reductions to meet cleaner fuels requirements and an enhanced program of refinery efficiency initiatives. Under the Base Case assumptions the CO2 emissions from refinery operations in 2010 would be about 3.4 below 1990 levels. The Kyoto Case was developed on the basis of reductions in Canadian petroleum product demand that would be sufficient to achieve a 6 per cent reduction in GHG emissions from the production and consumption of petroleum products relative to 1990 levels. The model demonstrates the dramatic economic impact of the Kyoto Case reductions on the Canadian downstream petroleum sector. Investment requirements for capital improvements to further distillate production and to further desulphurization are estimated at $ 1.5 billion between 2005 and 2015. The reduced volume of gasoline sales would be expected to result in rationalization of retail outlets, resulting in the closure of some 2,000 retail outlets with a combined loss of about 12,000 jobs. It is suggested that similar impact in other countries that are signatory to the Kyoto Protocol could result in the shift of refining, refining industry jobs and related economic benefits to countries which are not participants in the Kyoto Protocol. 14 tabs., 6 figs., 5 appendices

    Full Text Available The attitude of students towards the integration of the internet as a study tool and communication channel in teaching and learning in engineering has been investigated. A study was carried out in the Faculty of Engineering, Ahmadu Bello University Zaria, Nigeria, aimed at investigating the effect of certain variables such as gender, course of study, computer experience, and the percentage of internet usage on teaching and learning processes. A well-structured questionnaire was administered to a randomly selected five hundred (500 male and female students across the seven (7 departments of the faculty and about 85% were filled and returned. The study also examines the university management's perspectives and strategies to incorporate internet usage in teaching and learning processes especially in engineering. Amazingly, responses received showed that experience in the use of the computer in surfing the internet for problem based activities mainly affects the level of internet usage across the faculty. This factor makes some students to misplace their priority in internet usage emphasizing on e-mail correspondence and social networking rather than sourcing for information and solving problems as it is done by a few students. Furthermore, findings support that internet cannot entirely substitute for traditional teaching and learning processes like text reading but can serve as a reasonable alternative when the latter is unavailable

  13. Proposition of an Interactive Process Approach in Exploring the Relationship between Corporate Social Responsibility (CSR Strategy and Perceived CSR: Case of ExxonMobil in Nigeria’s Petroleum Industry

    Directory of Open Access Journals (Sweden)

    Ibe Chidi Michael

    2015-01-01

    Full Text Available Business organizations implement corporate social responsibility (CSR initiatives with an aim of generating business value. This has often been noted as a means of ensuring sustainable development (SD in the relationship between business and society. However, some recent cases have produced outcomes that are contrary to this view. This is evident in the Nigerian petroleum industry where multi-national oil companies like Exxon Mobil have contributed extensively to their host-communities without generating positive outcomes based on the implemented CSR initiatives. Inspite of their contributions, the stakeholders in their host communities engage in activities that threaten their sustainable development. This outcome reflects a gap in the theory and practice of CSR. This gap was explored through critically examining the case of ExxonMobil with focus on their CSR activities and outcomes. It was revealed that the focus of extant literature on corporate perspective in CSR implementation and the extensive empirical focus on the direct relationship between CSR strategy and perceived CSR lead to a narrow view of the CSR concept. The need to adopt an interactive process approach through looking at the antecedents and outcomes in the relationship between CSR strategy and perceived CSR was proposed as a means of grasping the nature of outcomes generated from CSR.

    2003-01-01

    The United Nations has developed an international framework classification for solid fuels and minerals (UNFC). This is now being extended to petroleum by building on the joint classification of the Society of Petroleum Engineers (SPE), the World Petroleum Congresses (WPC) and the American Association of Petroleum Geologists (AAPG). The UNFC is a 3-dimansional classification. This: Is necessary in order to migrate accounts of resource quantities that are developed on one or two of the axes to the common basis; Provides for more precise reporting and analysis. This is particularly useful in analyses of contingent resources. The characteristics of the SPE/WPC/AAPG classification has been preserved and enhanced to facilitate improved international and national petroleum resource management, corporate business process management and financial reporting. A UN intergovernmental committee responsible for extending the UNFC to extractive energy resources (coal, petroleum and uranium) will meet in Geneva on October 30th and 31st to review experiences gained and comments received during 2003. A recommended classification will then be delivered for consideration to the United Nations through the Committee on Sustainable Energy of the Economic Commission for Europe (UN ECE).

  19. Concrete release protocol case studies for decommissioning work at the Idaho National Engineering and Environmental Laboratory

    International Nuclear Information System (INIS)

    The US Department of Energy (DOE) Order 5400.5, ''Radiation Protection of the Public and Environment'' contains provisions pertinent to releasing potentially radioactive materials from DOE facilities for reuse or recycle. A process of authorized release for materials recovered from radiation areas is permitted under Order 5400.5 and the proposed rule in Title 10, Part 834, of the Code of Federal Regulations (10 CFR Part 834). A generic disposition protocol to facilitate release of concrete under these provisions has been developed. This report analyzes the application of that generic protocol to site-specific cases at the Idaho National Engineering and Environmental Laboratory (INEEL). The potential radiological doses and costs for several concrete disposition alternatives for the sewage treatment plant (STP) at the Central Facilities Area (CFA) of INEEL were evaluated in this analysis. Five disposition alternatives were analyzed for the concrete: (A) decontaminate, crush, and reuse; (B) crush and reuse without decontamination; (C) decontaminate, demolish, and dispose of at a nonradiological landfill; (D) demolish and dispose of at a nonradiological landfill without decontamination; and (E) demolish and dispose of at a low-level radioactive waste (LLW) facility. The analysis was performed for disposition of concrete from four INEEL structures: (1) trickle filter, (2) primary clarifier, (3) secondary clarifier, and (4) CFA-691 pumphouse for a generic case (based on default parameters from the disposition protocol) and an INEEL-specific case (based on INEEL-specific parameters). The results of the analysis indicated that Alternatives B and D would incur the lowest cost and result in a dose less than 1 mrem/yr (except for the trickle filter, the dose for which was estimated at 1.9 mrem/yr) for nonradiological workers. The analysis indicated that the main contributor to the radiological dose would be cobalt-60 contamination in the concrete. A characterization conducted

  6. International petroleum exploration and exploitation agreements: a comprehensive environmental appraisal

    International Nuclear Information System (INIS)

    The evolution of the environmental aspects of international petroleum exploration and exploitation is outlined. Four case studies of modern petroleum contracts from four developing countries are presented. These are Thailand's modern concession contract, Indonesia's production sharing contract, Brazil's risk service contract and China's hybrid contract. The failure of these four countries to provide adequate environmental regulation through their petroleum contracts is typical of many countries in the developing world. An urgent need exists to recognise that important environmental and resource consequences are associated with the developments authorised by petroleum contracts and that appropriate legal changes must be made to take them into account. Environmental sustainability should be an explicit part of all investment arrangements. (UK)

  7. Purification by mussels of petroleum-containing seawater

    Mironov, O.G.; Shchekaturina, T.L.; Stepanets, L.G.; Yanov, B.G.

    1981-01-01

    A solution to the problem of thorough purification of petroleum-containing ballast waters, taking place during the emptying of tankers in bulk oil ports is presented. The fact of removal by mussels of petroleum pollution components from sea water points to the possibility and advisability of using them in a system for hydrobiological purification of petroleum-containing sea water. The optimal number of mussel specimens necessary for water purification will depend on the sizes of the organisms and the flow rate of the channel of petroleum-containing water. Under certain conditions a decrease in the deaths of hydrobionts can be gotten, for example by reducing the time of their being found in the affecting volume of waste water. In this case a removable-cell arrangement of the mussels which facilitates also the task of removal of dead organisms shows promise.

  8. Risk analysis associated with petroleum hydrocarbons: is everything running smoothly?

    International Nuclear Information System (INIS)

    Petroleum products represent one of the main sources of environmental contamination, and these products are complex, composed of several hundred individual hydrocarbons. The evaluation of the risks associated with petroleum products is often limited by certain specific parameters such as benzene. The petroleum hydrocarbons running from C(10) to C(50) are not often integrated in an analysis of the toxological risks since the toxological characterization of a complex mixture of hydrocarbons is difficult to carry out. There exist in the United States two approaches that were developed recently that allow the integration of various hydrocarbons comprising a mixture. In this presentation, two of these approaches are described and compared. An overview of these approaches related to Canadian regulatory bodies is included, and a case study completes the account. The two approaches that are most well known in this area are: 1) that of the Massachusetts Dept. of Environmental Protection, and 2) that of the Total Petroleum Hydrocarbon Criteria Working Group. The integration of petroleum hydrocarbons in a quantitative evaluation of their toxological risk is possible by present methods. This integration allows a reduction in the uncertainty associated with the use of an integrating parameter in the case of these petroleum hydrocarbons in the C(10) to the C(50) range

    Full Text Available This empirical study was conducted to determine factors that influence the career choice among engineers in a Malaysian manufacturing plant. Subjects of this study were taken from engineers in one of manufacturing plant in Malaysia. As hypothesized, the results suggest that perceptions of person-job fit and financial rewards are significant factors that influence the career choice of engineers. Contrast to our hypothesis, influence from family members does not have any impact in determining the career choice among engineers. Interventions in attracting more engineers to remain in their career path and limitations of the study are also being discussed in the paper.

  12. Petroleum biodegradation and oil spill bioremediation

    International Nuclear Information System (INIS)

    Hydrocarbon-utilizing microorganisms are ubiquitously distributed in the marine environment following oil spills. These microorganisms naturally biodegrade numerous contaminating petroleum hydrocarbons, thereby cleansing the oceans of oil pullutants. Bioremediation, which is accomplished by adding exogenous microbial populations or stimulating indigenous ones, attempts to raise the rates of degradation found naturally to significantly higher rates. Seeding with oil degraders has not been demonstrated to be effective, but addition of nitrogenous fertilizers has been shown to increase rates of petroleum biodegradation. In the case of the Exxon Valdez spill, the largest and most thoroughly studied application of bioremediation, the application of fertilizer (slow release or oleophilic) increased rates of biodegradation 3-5 times. Because of the patchiness of oil, an internally conserved compound, hopane, was critical for demonstrating the efficacy of bioremediation. Multiple regression models showed that the effectiveness of bioremediation depended upon the amount of nitrogen delivered, the concentration of oil, and time. (author)

Based on available well data, the rifting probably began in the Cretaceous time had continued until Paleocene. It is considered that compressional force immediately after rifting event deformed sedimentary sections. During the period of Paleocene to middle Miocene, the sediments were deposited in stable environment without particular tectonic event. 2) Petroliferous basin analysis in Taegu area (II): The Nakdong and Jinju formations contain abundant black shales, and thermal maturity of the organic matter reached at the final stage of dry gas generation. These formations also contain thick sandstones which can act as a petroleum reservoir. However, reservoir quality of the sandstones is poor (porosity: < 5%; permeability: < 0.001 md). In these sandstones, secondary pores such as dissolution pores and micropores can act as a tight gas reservoir. (author). 56 refs., 24 tabs., 68 figs.

    2016-01-01

    Full Text Available Mobile healthcare systems are currently considered as key research areas in the domain of software engineering. The adoption of modern technologies, for mobile healthcare systems, is a quick option for industry professionals. Software architecture is a key feature that contributes towards a software product, solution, or services. Software architecture helps in better communication, documentation of design decisions, risks identification, basis for reusability, scalability, scheduling, and reduced maintenance cost and lastly it helps to avoid software failures. Hence, in order to solve the abovementioned issues in mobile healthcare, the software architecture is integrated with personal software process. Personal software process has been applied successfully but it is unable to address the issues related to architectural design and evaluation capabilities. Hence, a new technique architecture augmented personal process is presented in order to enhance the quality of the mobile healthcare systems through the use of architectural design with integration of personal software process. The proposed process was validated by case studies. It was found that the proposed process helped in reducing the overall costs and effort. Moreover, an improved architectural design helped in development of high quality mobile healthcare system.

    The application of biotechnology to the production of commodity products (fuels, chemicals, and materials) offering benefits in terms of sustainable resource supply and environmental quality is an emergent area of intellectual endeavor and industrial practice with great promise. Such "biocommodity engineering" is distinct from biotechnology motivated by health care at multiple levels, including economic driving forces, the importance of feedstocks and cost-motivated process engineering, and the scale of application. Plant biomass represents both the dominant foreseeable source of feedstocks for biotechnological processes as well as the only foreseeable sustainable source of organic fuels, chemicals, and materials. A variety of forms of biomass, notably many cellulosic feedstocks, are potentially available at a large scale and are cost-competitive with low-cost petroleum whether considered on a mass or energy basis, and in terms of price defined on a purchase or net basis for both current and projected mature technology, and on a transfer basis for mature technology. Thus the central, and we believe surmountable, impediment to more widespread application of biocommodity engineering is the general absence of low-cost processing technology. Technological and research challenges associated with converting plant biomass into commodity products are considered relative to overcoming the recalcitrance of cellulosic biomass (converting cellulosic biomass into reactive intermediates) and product diversification (converting reactive intermediates into useful products). Advances are needed in pretreatment technology to make cellulosic materials accessible to enzymatic hydrolysis, with increased attention to the fundamental chemistry operative in pretreatment processes likely to accelerate progress. Important biotechnological challenges related to the utilization of cellulosic biomass include developing cellulase enzymes and microorganisms to produce them, fermentation of

    ENGLISH ABSTRACT: Value engineering (VE has been effectively applied in many different areas. The results have been very encouraging, and many companies accept VE not only as a tool to reduce costs, but also to improve the quality of their produce and streamline their systems. This paper attempts to highlight the application of VE in agriculture, as in pistachio tree farms in Iran. It is found that by implementing VE, unnecessary cultivation costs are lowered. Many of the other factors that lead to the inefficient use of resources could be resolved. In this study, the province of Yazd Iran was studied. Unfortunately there are cases of mismanagement and problems in agriculture management; and the problems must be resolved to make the system of pistachio growing more efficient. The prime objective of this paper is to introduce the concept of value engineering and highlight its application in pistachio farms. The results suggest that it is essential to use Indian Neem pesticide, because it is economically feasible and environmentally friendly to pistachio trees.

    1998-01-01

    Software is becoming increasingly significant in today's critical avionics systems. To achieve safe, reliable software, government regulatory agencies such as the Federal Aviation Administration (FAA) and the Department of Defense mandate the use of certain software development methods. However, little scientific evidence exists to show a correlation between software development methods and product quality. Given this lack of evidence, a series of experiments has been conducted to understand why and how software fails. The Guidance and Control Software (GCS) project is the latest in this series. The GCS project is a case study of the Requirements and Technical Concepts for Aviation RTCA/DO-178B guidelines, Software Considerations in Airborne Systems and Equipment Certification. All civil transport airframe and equipment vendors are expected to comply with these guidelines in building systems to be certified by the FAA for use in commercial aircraft. For the case study, two implementations of a guidance and control application were developed to comply with the DO-178B guidelines for Level A (critical) software. The development included the requirements, design, coding, verification, configuration management, and quality assurance processes. This paper discusses the details of the GCS project and presents the results of the case study.

    2016-04-01

    Full Text Available A capstone project in current engineering education is often introduced to enable the holistic attainment of engineering knowledge by an engineering undergraduate. Essentially project-based in nature, there exists a need to ensure that part of the attainment process involves key industry practices – such practices being necessary in attaining the status of a professional engineer. Herein lies the synergy that can be made use of between industry and academia. By exposing engineering undergraduates to a project which addresses an engineering challenge and providing them with the opportunity to learn from professional engineers who are experts in the fields of safety, sustainability, quality management, ethics and project management, this culminates in the implementation of a prototype design which incorporates the amalgamation of knowledge from industry and academia. This paper presents the unique curriculum developed in a capstone project module, incorporating learning sessions from professional engineers in the five (5 key areas of industry practice highlighted above and how these have contributed to significantly enhancing the learning outcome and hence programme outcome attainment of the engineering undergraduates who have experienced the module.

    and gas endowment estimates. Whereas petroleum resources in the world appear to be significant, certain countries such as the United States may run into import deficits, particularly oil imports from Mexico and natural gas from both Canada and Mexico. The new assessment has been used as the reference supply case in energy supply models by the International Energy Agency and the Energy Information Agency of the Department of Energy. Climate energy modeling groups such as those at Stanford University, Massachusetts Institute of Technology, and others have also used USGS estimates in global climate models. Many of these models using the USGS estimates converge on potential oil shortfalls in 2036-2040. However, recent articles using the USGS (2000) estimates suggest peaking of oil in 2020-2035 and peaking of non-OPEC (Organization of Petroleum-Exporting Countries) oil in 2015-2020. Such a short time framework places greater emphasis on a transition to increased use of natural gas; i.e., a methane economy. Natural gas in turn may experience similar supply concerns in the 2050-2060 time frame according to some authors. Coal resources are considerable and provide significant petroleum potential either by extracting natural gas from them, by directly converting them into petroleum products, or by utilizing them to generate electricity, thereby reducing natural gas and oil requirements by fuel substitution. Non-conventional oil and gas are quite common in petroleum provinces of the world and represent a significant resources yet to be fully studied and developed. Seventeen non-conventional AU including coal-bed methane, basin-center gas, continuous oil, and gas hydrate occurrences have been preliminarily identified for future assessment. Initial efforts to assess heavy oil deposits and other non-conventional oil and gas deposits also are under way.

  12. Petroleum and the economy

    International Nuclear Information System (INIS)

    In re-examining the effect of energy price shocks on the economy, this article applies several tests to show that the apparent coincidence between price shocks and poor economic performance may be misleading. For example, whereas macroeconomic analysis graphs of employment and GNP clearly indicate an apparent correlation between the 1979 petroleum price hike and economic downturn in the USA, Great Britain and Germany, Japan's performance stayed fairly constant during that period. Additional sectoral analyses of the performances of the western economies show that the impacts of the '74 and '79 oil price shocks were not equally distributed across the different industrial sectors of the various nations. The paper argues that a deeper understanding of the energy-economy relationship is required to reduce these ambiguities

  13. Petroleum Business in Nigeria

    International Nuclear Information System (INIS)

    The petroleum industry is vital to the health of the Nigerian economy as it accounts for over 80% of Nigeria's total export earnings and about 70% of total government revenue. Nigeria has an oil reserve base of 21 billion barrels and gas reserve of 120 trillion cubic feet. With natural gas becoming the worlds fastest growing energy resource, the Nigerian Government has put in place a program to grow her oil reserve base to over 25 billion barrels and significantly increase her gas reserves. An earlier commitment made in 1990 to increase Nigeria's oil reserve base from a level of 16 to 20 billion barrels by 1995 was achieved well ahead of time. This success was largely due to financial incentives offered investors. This healthy business climate still prevails. This paper presents the investment opportunities that Nigeria offers genuine investors in both the upstream and downstream sectors of the industry and defines the legal/regulatory requirements for doing business in Nigeria. We try to give an insight into specific government policies that help to create an enabling environment for investors in the upstream and downstream sectors of the petroleum industry. We showcase the 5 (five) major sedimentary basins with enormous oil and gas potential where exploration/exploitation risks are rated medium to low. We focus on the environment and government's efforts to enforce the rules and guidelines that govern the policy termed the Environment, Safety and Standards. We recognize that the business challenges of the third millennium will dictate new alliances and partnerships that will survive and thrive only in a climate that is safe for the investor. This is the business climate we throw open in Nigeria for investors to come in and do business with us

    International Nuclear Information System (INIS)

    Oil and gas production is the basis of economy of the Azerbaijan Republic and its cause in ecological and radioecology problems. One form this problem is the pollution by radionuclides of environment at the time of gas and petroleum production. At the time of petroleum and gas production the three-phase radionuclides are emitted in atmosphere: Emissions consisted from solid U-238, Ra-226, Th-232, K-40 discharged to atmosphere at the time of production, exploring and exploitation of petroleum and gas. They are presented in compounds of sand, clay, and petroleum residues; During the drilling and production the gross quantities of water flows out and collects. These water areas consist of radium, uranium, Th and K-40 dissolved in water salts; There are the radionuclides being in 902 condition emitted in atmosphere at the places of petroleum and gas production. The radon and its isotopes are emitted at this time; At the places of petroleum and gas production it is observed at local pollution areas polluted by solid emissions that at this territories the doze of exposition power variable 100 - 1000 micro/hour. The radioactivity at this system according to 2-1000 year/k consists from Ra, K-40, and U. At this areas the value of total background changes 5 - 1000 micro R/hour. The total radioactivity of water polls formed at the places of petroleum and gas production consisted 50 -150 Bq/L. In the case of gas the separated radionuclides are mainly consisted from Radon and its isotopes. In the compound of produced gas the concentration of radon varied 20 - 1700 Bq/m3. Thus, at the places of petroleum and gas production radioactive pollutants emitted to atmosphere, forms the polluted environment for working and living people at the same territory. This problem's status haven't been investigated thoroughly, the sources of pollution hasn't been uncovered concretely, the cleaning technology for polluted areas is unknown

  6. Engineering estimates versus impact evaluation of energy efficiency projects: Regression discontinuity evidence from a case study

    International Nuclear Information System (INIS)

    Energy efficiency upgrades have been gaining widespread attention across global channels as a cost-effective approach to addressing energy challenges. The cost-effectiveness of these projects is generally predicted using engineering estimates pre-implementation, often with little ex post analysis of project success. In this paper, for a suite of energy efficiency projects, we directly compare ex ante engineering estimates of energy savings to ex post econometric estimates that use 15-min interval, building-level energy consumption data. In contrast to most prior literature, our econometric results confirm the engineering estimates, even suggesting the engineering estimates were too modest. Further, we find heterogeneous efficiency impacts by time of day, suggesting select efficiency projects can be useful in reducing peak load. - Highlights: • Regression discontinuity used to estimate energy savings from efficiency projects. • Ex post econometric estimates validate ex ante engineering estimates of energy savings. • Select efficiency projects shown to reduce peak load

  12. Sense and Sensibility: The Case for the Nationwide Inclusion of Engineering in the K-12 Curriculum

    Science.gov (United States)

    Lindberg, Robert E.; Pinelli, Thomas E.; Batterson, James G.

    2008-01-01

    The competitive status of the United States is inextricably linked to innovation just as innovation is inseparable from science, technology, engineering, and mathematics. To stay competitive in innovation requires that the United States produce a 21st century workforce complete with requisite education, training, skills, and motivation. If we accept a priori that science, technology, engineering, and mathematics education are crucial to competitiveness and innovation and that, in terms of innovation, mathematics, science, and engineering are interdependent, why are mathematics and science uniformly ubiquitous in the K-12 curriculum while engineering is conspicuously absent? We are passionate in our belief that the uniform addition of engineering to the K-12 curriculum will help ensure that the nation has "the right" 21st Century workforce. Furthermore, we believe that a nationwide effort, led by a coalition of engineering academics, practitioners, and societies is required to turn this goal into reality. However, accomplishing this goal necessitates, as we are reminded by the title of Jane Austen's timeless novel, "Sense and Sensibility", a workable solution that seeks the "middle ground" between passion and reason. We begin our paper by making two essential points: Engineers are not scientists. Engineering exists separate from science, has its own specialized knowledge community apart from science, and it is largely responsible for many of the most significant advancements and improvements in the quality of our life. Our workable solution requires that K-12 education, nationwide, accommodate the inclusion of engineering as a stand alone curriculum and we offer three reasons to support our position: (1) workforce development, (2) stimulating interest in STEM (science, technology, engineering, and mathematics) courses and careers, and (3) creating a technologically literate society. We conclude with some thoughts on how this important goal can be accomplished.

    2008-01-01

    In 2004, NASA faced major knowledge sharing challenges due to geographically isolated field centers that inhibited personnel from sharing experiences and ideas. Mission failures and new directions for the agency demanded better collaborative tools. In addition, with the push to send astronauts back to the moon and to Mars, NASA recognized that systems engineering would have to improve across the agency. Of the ten field centers, seven had not built a spacecraft in over 30 years, and had lost systems engineering expertise. The Systems Engineering Community of Practice came together to capture the knowledge of its members using the suite of collaborative tools provided by the NASA Engineering Network (NEN.) The NEN provided a secure collaboration space for over 60 practitioners across the agency to assemble and review a NASA systems engineering handbook. Once the handbook was complete, they used the open community area to disseminate it. This case study explores both the technology and the social networking that made the community possible, describes technological approaches that facilitated rapid setup and low maintenance, provides best practices that other organizations could adopt, and discusses the vision for how this community will continue to collaborate across the field centers to benefit the agency as it continues exploring the solar system.

  18. Re-Os geochronology and Os isotope fingerprinting of petroleum sourced from a Type I lacustrine kerogen: insights from the natural Green River petroleum system in the Uinta Basin and hydrous pyrolysis experiments

    Science.gov (United States)

    Rhenium–osmium (Re–Os) geochronology of marine petroleum systems has allowed the determination of the depositional age of source rocks as well as the timing of petroleum generation. In addition, Os isotopes have been applied as a fingerprinting tool to correlate oil to its source unit. To date, only classic marine petroleum systems have been studied. Here we present Re–Os geochronology and Os isotope fingerprinting of different petroleum phases (oils, tar sands and gilsonite) derived from the lacustrine Green River petroleum system in the Uinta Basin, USA. In addition we use an experimental approach, hydrous pyrolysis experiments, to compare to the Re–Os data of naturally generated petroleum in order to further understand the mechanisms of Re and Os transfer to petroleum. The Re–Os geochronology of petroleum from the lacustrine Green River petroleum system (19 ± 14 Ma – all petroleum phases) broadly agrees with previous petroleum generation basin models (∼25 Ma) suggesting that Re–Os geochronology of variable petroleum phases derived from lacustrine Type I kerogen has similar systematics to Type II kerogen (e.g., Selby and Creaser, 2005a, Selby and Creaser, 2005b and Finlay et al., 2010). However, the large uncertainties (over 100% in some cases) produced for the petroleum Re–Os geochronology are a result of multiple generation events occurring through a ∼3000-m thick source unit that creates a mixture of initial Os isotope compositions in the produced petroleum phases. The 187Os/188Os values for the petroleum and source rocks at the time of oil generation vary from 1.4 to 1.9, with the mode at ∼1.6. Oil-to-source correlation using Os isotopes is consistent with previous correlation studies in the Green River petroleum system, and illustrates the potential utility of Os isotopes to characterize the spatial variations within a petroleum system. Hydrous pyrolysis experiments on the Green River Formation source rocks show that Re and Os transfer

  20. Diterpenoid tetracyclic hydrocarbons of petroleum

    Energy Technology Data Exchange (ETDEWEB)

    1987-08-01

    Diterpenoid hydrocarbons are fairly widespread in various caustobioliths. However, if petroleums contain mainly acyclic diterpenoids (phytane, pristane and norpristane), cyclic diterpaenes such as fichtelite, pimarane, iosene (kaurane) and hibbane are often found in hydrocarbons isolated from coal and shale. Recent advances in the chemistry of diterpenoids isolated from caustobioliths, are described in a separate paper. Much less is known about petroleum polycyclic diterpenoid hydrocarbons, particularly those with four saturated rings. A series of tetracyclic hydrocarbons C/sub 19/H/sub 32/ (molar mass 260), found in a number of light petroleums and gas condensates from the Jura deposits of Central Kara-Kum (Turkmen S.S.R.), are examined here. These hydrocarbons are present in petroleums and condensates from the Davaly, Erden, Ortakak, Southern Beuideshik deposits, they are always identical and occur in the same ratios. The composition of the tretracyclanes isolated from the Ortakak gas condensates (well 17) will be examined in detail.

  3. The Strategic Petroleum Reserve: United States energy security, oil politics, and petroleum reserves policies in the twentieth century

    Science.gov (United States)

    Beaubouef, Bruce Andre

    The history of U.S. petroleum reserves policies in the twentieth century, including the Strategic Petroleum Reserve (SPR) program, provides a case study of the economic and political aspects of national security, and shows the ways in which the American political economy influences national security. One key problem plagued federal petroleum reserve programs and proposals throughout the twentieth century. In a political economy which traditionally placed strong emphasis upon the sanctity of private property and free markets, could the government develop an emergency petroleum reserve policy despite opposition from the private sector? Previous literature on the SPR and oil-stockpiling programs has largely disregarded the historical perspective, focusing instead upon econometric models, suggesting future oil-stockpiling policy options. This study will also make conclusions about the future of governmental oil-stockpiling policies, particularly with regard to the SPR program, but it will do so informed by a systematic history of the emergency petroleum reserve impulse in the twentieth century. Through a study of the emergency petroleum reserve impulse, one can see how the American political economy of oil and energy changed over the twentieth century. As petroleum became crucial to the military and then economic security of the United States, the federal government sought to develop emergency petroleum reserves first for the military, then for the civilian economy. But while the American petroleum industry could deliver the energy "goods" to American energy consumers at a reasonable price, the companies reigned supreme in the political equation. While that was true, federal petroleum reserve programs and proposals conflicted with and were overwhelmed by the historic American tradition of individual economic and private property rights. The depletion of American petroleum reserves changed that political equation, and the ensuing energy crises of the 1970s not only

  17. Canadian retail petroleum markets study

    International Nuclear Information System (INIS)

    A retail petroleum market study was conducted to provide a comprehensive overview of the competitiveness of the downstream petroleum industry in Canada and to set a foundation for effective policy development. The downstream petroleum industry, which includes the petroleum refining and marketing sectors, faces a poor public image, competitive pressures from U.S. and offshore refiners, and a broad range of environmental challenges. In this study, 19 markets representing a wide range of conditions were chosen for a detailed review of outlet economics. A market-by-market and regional comparisons of key competitiveness indicators was made in order to identify market and regional competitive differences as potential issues or opportunities within the industry. The study also included a pump price/margin model and provided a general overview of the retail gasoline sub-sector in terms of infrastructure. A review of prices, margins and demand patterns over the past several years was also undertaken to show the relationship between consumer demand patterns and pump price fluctuations. The study presented 22 findings which led to several conclusions and recommendations regarding the competitiveness of Canada's petroleum marketing sector. Two of the key conclusions were that taxation is a significant factor in the price of retail gasoline (about 50 per cent) and that government intervention into petroleum marketing is likely to be a poor alternative to market-based regulation. 18 tabs., 37 figs

    Olgaard, D. L.; Tikku, A.; Roberts, J. C.; Martinez, A.

    2012-12-01

    Meeting the increasing global demand for energy over the next several decades presents daunting challenges to engineers and scientists, including geoscientists of all disciplines. Many opportunities exist for geophysicists to find and produce oil and gas in a safe, environmentally responsible and affordable manner. Successful oil and gas exploration involves a 'Plates to Pores' approach that integrates multi-scale data from satellites, marine and land seismic and non-seismic field surveys, lab experiments, and even electron microscopy. The petroleum industry is at the forefront of using high performance computing to develop innovative methods to process and analyze large volumes of seismic data and perform realistic numerical modeling, such as finite element fluid flow and rock deformation simulations. Challenging and rewarding jobs in exploration, production and research exist for students with BS/BA, MS and PhD degrees. Geophysics students interested in careers in the petroleum industry should have a broad foundation in science, math and fundamental geosciences at the BS/BA level, as well as mastery of the scientific method, usually gained through thesis work at MS and PhD levels. Field geology or geophysics experience is also valuable. Other personal attributes typical for geoscientists to be successful in industry include a passion for solving complex geoscience problems, the flexibility to work on a variety of assignments throughout a career and skills such as teamwork, communication, integration and leadership. In this presentation we will give examples of research, exploration and production opportunities for geophysicists in petroleum companies and compare and contrast careers in academia vs. industry.

    The goal of this record of study is to examine the major facets involved in managing several petroleum service projects located in three different countries in the Gulf of Guinea simultaneously, while effectively engaging in business development activities for the Oil and Industrial Services Group (OIS). This work also furnishes adequate background on related subject matters to enable understanding of the projects presented. The petroleum services sector is the back bone of the oil and gas industry. Services companies are vital to the success of all petroleum and energy producers in the USA, the Gulf of Guinea and the world. There is a need and demand for these service companies because they play various roles such as logistics, drilling, construction, dredging, pipe laying, procurement, food supply, human resource supply, etc. The Gulf of Guinea comprises of countries from west and central Africa. This project was limited to Nigeria, Equatorial Guinea and Cameroon. This area holds the largest petroleum reserves in Africa and plays a vital role in the global supply of petroleum. The Oil and Industrial Services Group (OIS), plans to establish herself as one of the leading petroleum service companies in this gulf. To manage this expansion, I have taken the role of Gulf of Guinea manager to apply my background as a petroleum engineer as well as my business skills to build a successful division of the company. This work provides a record of study of the management of services, projects and contracts carried out by the OIS group in the gulf of Guinea. The following are the specific projects in the Gulf of Guinea that I participated in: Managing delivering, maintenance and marketing of offshore vessels, Offshore pipe laying project, Integrated pipeline maintenance project, Development a petroleum technical training facilities, Agbami pipe insulation project, Engineering lift project and Capital budgeting analysis for potential investments.

    Activities of the Nova Scotia Registry of Mineral and Petroleum Titles are described, including statistical information about staking and mining activity in the province during 1999. In terms of activities, the Registry receives applications and issues licenses and leases for mineral and petroleum rights, receives statements of exploration expenditures and assessment reports that pertain to renewal of licenses and leases, maintains maps showing the disposition of lands under license or lease, and maintains a system of prospector registration. In addition, the Registry processes applications for underground gas storage rights and treasure trove rights and maintains a database of information concerning production and employment in Nova Scotia mines and quarries. At the end 1999 there were 230,660 hectares under exploration licence. Exploration expenditures, including engineering, economic and feasibility studies during 1999 totalled $4.2 million, mostly by junior mining companies searching for industrial mineral commodities. Mining activity during 1999 generated revenues of $340 million. Coal production dropped by 25 per cent, due mainly to the closure of the Phalen Mine. Gypsum production was up to 7.9 million tonnes; shipments of cement, barite and clay products also increased during 1999; salt production remained unchanged from 1998 with 842,000 tonnes. Production of construction aggregates totalled 10.6 million tonnes, down slightly from the year before. Mineral industry employment was roughly 2,500 persons, down by 24 per cent from 1998 levels, due primarily to the closure of the Phalen Mine.

    This report consists of 2 subjects. 1) Petroleum resources assessment of the Kunsan Basin : Kunsan Basin is mainly filled with Cretaceous and Tertiary clastic sediments, and divided into Southwest Sub-basin, Central Sub-basin and Northeast Sub-basin by uplifts and faults developed in the basin. Microfossils were studied for the biostratigraphic works of drill wells in the Kunsan Basin. The microfossils include organic-walled microfossils such as spores, pollen and nonmarine dinoflagellates and calcareous microfossils such as ostracods, charophytes and gastropods. The fossil assemblages of the Kunsan Basin reveal nonmarine environments ranging from alluvial fan to shallow lacustrine and climatic variation between subtropical and cool temperate temperature in the arid/humid alternating conditions. According to the paleontological data, the Kunsan Basin was initiated in the Early Cretaceous and expanded during Paleogene followed by regional erosion at the closing time of Paleogene on which Neogene sediments have been accumulated. The Paleogene strata show laterally irregular thickness in each Epoch due to migrating depocenter. 2) Petroliferous basin analysis in Hapcheon area (I) : The Cretaceous Gyeongsang Supergroup consists of more than 9 Km sequences of sedimentary and volcanic rocks in Hapcheon-Changyong-Euiryong-Haman area and occupies the middle part of the Milyang subbasin. The Supergroup can be divided into three group; Sindong, Hayang and Yuchon groups in ascending order. Based on rock color, the Sindong Group can be subdivided into Nakdong, Hasandong and Jinju Formations. The Hayang Group can be subdivided into Chilgok, Silla Conglomerate, Haman and Jindong Formations. The Chilgok Formation includes basaltic lava and tuffs in the upper part. The Haman Formation has Kusandong tuff (keybed) in the uppermost part in the Changyong area, whereas the tuff is intercalated below the vocaniclastics in the Haman area.

    On the basis of diverse microfossils such as foraminifers, ostracods, micromulluscs, fossil spores and pollen and calcareous nannofossils derived from 14 drill holes, the sediments are divided into two part, the upper marine part and the lower nonmarine one. Marine part is subdivided into 4 foraminiferal zones and 3 nannofossil zones of Plio-Pleistocene age. In the lower part ranging from Oligocene to Late Miocene 4 palynomoph assemblages are established, which reflect climatic changes fluctuating between subtropical and cool temperate. Some fine sediments occurring in the South Sea continental shelf are rich in organic matter to be hydrocarbon source rock. The organic matter is mainly compared to type 3. However, lower part of the Geobuk-1 and Okdom-1 shows more oil prone geochemical characteristics than other wells. The kerosene is mixture type 1 and type 3 organic matter. The main oil generation zone located between 2,500 m and 3,000 m and gas generation zone from 3,500 m to 4,000 m approximately. Hydrocarbon accumulation could be expected in the trap formed in the period earlier than 10 Ma. as the hydrocarbon started to be expelled at 10 Ma. according to the modeling. Approximately 13,000 Line-km of multichannel seismic data integrated with 14 wells and gravity and magnetic data were analyzed to investigate the structural and stratigraphic evolution of southern part of offshore Korea. The northeast-southwest trending Taiwan-Sinzi Uplift Belt separates the area into two regions with different tectonic features, northwestern and southwestern regions. The potential hydrocarbon traps associated with anticline, tilted fault block, fault, unconformity, and rollover structure exist. This project is consisted of two main subjects. 1) Petroleum resources assessment on the continental shelf basin of the south sea. 2) Petroliferous basin analysis in Taegu area (1).

    2012-06-01

    The subject 'Physical Fundamentals of Engineering' for agricultural engineers in the University of Extremadura has long had high rates of students not attending classes, not presenting for examinations and, finally, failing the subject. During the 2007 and 2008 courses, the teaching/learning procedures were strongly modified. Analysis of the proportion of students taking final examinations and of the final marks shows that the new procedure leads to a satisfactory progress in most of the objectives, including a general improvement in their marks and pass rates. In particular, it was found that the new procedure needs to be maintained by the teachers for at least two courses for the greatest success.

    2015-01-01

    The unusual GRB 110709B triggered Swift/BAT twice, with a time difference of $\\sim 11$ minutes. Its light curve presented three noticeable peaks but only two were originally identified. In this work, we describe each peak as due to a different central-engine phase: the first one is the millisecond-protomagnetar stage, the second one is the BH-formation collapse phase and the last one is the Collapsar scenario with a Blandford-Znajek engine. Additionally, we analyze and explain the afterglow phase evoking the standard fireball model. Our model can successfully describe the timescales, fluxes and spectral indices observed for GRB 110709B.

    We validated the usability of a new infusion pump interface designed with a situated Cognitive Engineering approach by comparing it to a reference interface using a novel testing method employing repeated measurements and process measures, in addition to traditional outcome measures. The sample consisted of 25 nurses who performed eight critical tasks three times. Performance measures consisted of number and type of errors, deviations from a pre-established normative path solution, task completion times, number of keystrokes, mental effort and preferences in use. Results showed that interaction with the new interface resulted in 18% fewer errors, 90% fewer normative path deviations, 42% lower task completion times, 40% fewer keystrokes, 39% lower mental effort and 76% more subjective preferences in use. These outcomes suggest that within the scope of this case study, combining the situated Cognitive Engineering approach with a novel testing method addresses various shortcomings of earlier testing methods.

    2013-04-01

    Full Text Available Although it is expected that research conducted at universities and institutions of higher learning will have some positive impact on the teaching quality, the literature seem to point in another direction. Available literature reports zero correlation between teaching and research. However, this need not be the case and a number of recommendations to create a positive correlation between teaching and research are proposed. This paper outlines a framework that utilises the Grand Challenges for Engineering and CDIO to create a clear link between teaching and research in Taylor’s School of Engineering. Aligning the academic staff research objectives to the Grand Challenges, creates a sense of purpose that extends beyond the academic staff to their students. Ensuring that students’ projects and other CDIO activities are derived from the academic staff research interests help creates a learning environment in which research and teaching are integrated. This integration is highly desirable as it benefits both the students and the academic staff.

  4. An intelligent decision support system for management of petroleum-contaminated sites

    International Nuclear Information System (INIS)

    Groundwater and soil contamination resulted from LNAPLs (light nonaqueous phase liquids) spills and leakage in petroleum industry is currently one of the major environmental concerns in North America. Numerous site remediation technologies have been developed and implemented in the last two decades. They are classified as ex-situ and in-situ remediation techniques. One of the problems associated with ex-situ remediation is the cost of operation. In recent years, in-situ techniques have acquired popularity. However, the selection of the optimal techniques is difficult and insufficient expertise in the process may result in large inflation of expenses. This study presents an expert system (ES) for the management of petroleum contaminated sites in which a variety of artificial intelligence (AI) techniques were used to construct a support tool for site remediation decision-making. This paper presents the knowledge engineering processes of knowledge acquisition, conceptual design, and system implementation. The results from some case studies indicate that the expert system can generate cost-effective remediation alternatives to assist decision-makers. (Author)

  6. Exports of petroleum products, 1988

    International Nuclear Information System (INIS)

    A summary is presented of exports of motor gasoline, middle distillate, aviation turbine fuel, heavy fuel oil, and partially processed oil from Canada for the 1988 calendar year. A discussion of petroleum product imports is included in order to put exports in the context of the overall trade. Exports of the above petroleum products averaged 32,000 m3/d in 1988, up 44% from 1987 levels. Each product except aviation fuel registered increases in export volumes, which reached the highest total volume of the decade. The main reason for the large increase was the first full year of production from the export-directed refinery at Come By Chance, Newfoundland. Export prices for light petroleum products stayed relatively close to USA spot prices. The heavy fuel oil price was mostly above the USA east coast spot price during 1988. Attractive prices on the USA east coast resulted in a few cargoes of middle distillate and motor gasoline shipped from British Columbia. Petroleum products imports came from 12 countries; Quebec had the largest volume of imports in 1988. The USA remained Canada's largest trading partner in petroleum products. Western exporters view the Far East as an ongoing important market. The top single exporter in Canada was Newfoundland Processing, with 32% of the total export volume. 12 figs., 3 tabs

    A summary is presented of exports of motor gasoline, middle distillate, aviation turbine fuel, heavy fuel oil, and partially processed oil from Canada for the 1989 calendar year. A discussion of petroleum product imports is included in order to put exports in the context of the overall trade. Exports of the above petroleum products averaged 30,400 m3/d in 1989, down 5% from 1988 levels. Motor gasoline shipments showed the largest decrease, down 1,500 m3 to 7,700 m3/d. Export prices for light petroleum products stayed relatively close to USA spot prices except in June and July 1989, when attractive prices were obtained for shipments from the prairie provinces. The heavy fuel oil export price was similar to the USA east coast spot price in 1989, except in December. Canada's petroleum products imports in 1989 were 21,600 m3/d, compared to 18,400 m3/d in 1988. Imports of heavy fuel oil in eastern Canada rose 36% in 1989 because of industries switching from electricity and the high demand for thermal power generation. The USA remained Canada's largest trading partner in petroleum products. The top single exporter in 1989, as in 1988, was Newfoundland Processing, with a volume of 3,484,500 m3. 24 figs., 4 tabs

  9. Fiberglass underground petroleum storage systems

    International Nuclear Information System (INIS)

    Fiberglass Reinforced Plastic (FRP) products have been in use for many years in a wide variety of products and markets. The automotive, marine, military, chemical, and petroleum markets have made extensive use of FRP. Today, over 300,000 FRP tanks and over 40,000,000 feet of FRP pipe are in service in petroleum marketing as well as industrial and commercial storage applications. In the early 1960's the American Petroleum Institute invited the FRP industry to design FRP underground tanks to solve their corrosion caused underground leaker problems. The challenge was accepted and in 1965 FRP tanks were introduced to the petroleum storage marketplace. FRP pipe, specifically designed for underground petroleum use, was Underwriter's Laboratories tested and listed and introduced in 1968. These fiberglass tanks and pipe have a 25 year perfect record against both internal and external corrosion. The FRP tank and pipe performance record has been outstanding. Less than 1/2 of 1% have ever been involved in an in-ground failure. When first introduced, FRP tanks carried an initial cost premium of 50 to 100% over unprotected steel. Since all Underground Storage Tank (UST) systems must be corrosion protected, initial FRP costs are now competitive with corrosion protected steel

  6. Primer for evaluating ecological risk at petroleum release sites.

    Claff, R

    1999-02-01

    Increasingly, risk-based approaches are being used to guide decision making at sites such as service stations and petroleum product terminals, where petroleum products have been inadvertently released to the soil. For example, the API Decision Support System software, DSS, evaluates site human health risk along six different routes of exposure. The American Society for Testing and Materials' Risk-Based Corrective Action (RBCA) standard, ASTM 1739, establishes a tiered framework for evaluating petroleum release sites on the basis of human health risk. Though much of the risk assessment focus has been on human health risk, regulatory agencies recognize that protection of human health may not fully protect the environment; and EPA has developed guidance on identifying ecological resources to be protected through risk-based decision making. Not every service station or petroleum product terminal site warrants a detailed ecological risk assessment. In some cases, a simple preliminary assessment will provide sufficient information for decision making. Accordingly, the American Petroleum Institute (API) is developing a primer for site managers, to assist them in conducting this preliminary assessment, and in deciding whether more detailed ecological risk assessments are warranted. The primer assists the site manager in identifying relevant ecological receptors and habitats, in identifying chemicals and exposure pathways of concern, in developing a conceptual model of the site to guide subsequent actions, and in identifying conditions that may warrant immediate response.

  7. Case study: Comparison of motivation for achieving higher performance between self-directed and manager-directed aerospace engineering teams

    Science.gov (United States)

    Erlick, Katherine

    "The stereotype of engineers is that they are not people oriented; the stereotype implies that engineers would not work well in teams---that their task emphasis is a solo venture and does not encourage social aspects of collaboration" (Miner & Beyerlein, 1999, p. 16). The problem is determining the best method of providing a motivating environment where design engineers may contribute within a team in order to achieve higher performance in the organization. Theoretically, self-directed work teams perform at higher levels. But, allowing a design engineer to contribute to the team while still maintaining his or her anonymity is the key to success. Therefore, a motivating environment must be established to encourage greater self-actualization in design engineers. The purpose of this study is to determine the favorable motivational environment for design engineers and describe the comparison between two aerospace design-engineering teams: one self-directed and the other manager directed. Following the comparison, this study identified whether self-direction or manager-direction provides the favorable motivational environment for operating as a team in pursuit of achieving higher performance. The methodology used in this research was the case study focusing on the team's levels of job satisfaction and potential for higher performance. The collection of data came from three sources, (a) surveys, (b) researcher observer journal and (c) collection of artifacts. The surveys provided information regarding personal behavior characteristics, potentiality for higher performance and motivational attributes. The researcher journal provided information regarding team dynamics, individual interaction, conflict and conflict resolution. The milestone for performance was based on the collection of artifacts from the two teams. The findings from this study illustrated that whether the team was manager-directed or self-directed does not appear to influence the needs and wants of the

  8. A case study of the knowledge transfer practices from the perspectives of highly experienced engineers in the aerospace industry

    Science.gov (United States)

    Martin, Deloris

    Purpose. The purpose of this study was to describe the existing knowledge transfer practices in selected aerospace companies as perceived by highly experienced engineers retiring from the company. Specifically it was designed to investigate and describe (a) the processes and procedures used to transfer knowledge, (b) the systems that encourage knowledge transfer, (c) the impact of management actions on knowledge transfer, and (d) constraining factors that might impede knowledge transfer. Methodology. A descriptive case study was the methodology applied in this study. Qualitative data were gathered from highly experienced engineers from 3 large aerospace companies in Southern California. A semistructured interview was conducted face-to-face with each participant in a private or semiprivate, non-workplace setting to obtain each engineer's perspectives on his or her company's current knowledge transfer practices. Findings. The participants in this study preferred to transfer knowledge using face-to-face methods, one-on-one, through actual troubleshooting and problem-solving scenarios. Managers in these aerospace companies were observed as having knowledge transfer as a low priority; they tend not to promote knowledge transfer among their employees. While mentoring is the most common knowledge transfer system these companies offer, it is not the preferred method of knowledge transfer among the highly experienced engineers. Job security and schedule pressures are the top constraints that impede knowledge transfer between the highly experienced engineers and their coworkers. Conclusions. The study data support the conclusion that the highly experienced engineers in the study's aerospace companies would more likely transfer their knowledge to those remaining in the industry if the transfer could occur face-to-face with management support and acknowledgement of their expertise and if their job security is not threatened. The study also supports the conclusion that managers

  9. Practical experience in the remediation of subsurface petroleum contamination

    International Nuclear Information System (INIS)

    Of the approximately 200,000 underground tank systems in Canada, an estimated 5-10% have been leaking, usually the result of corrosion or faulty equipment. In a worst case scenario, the volume of lost gasoline or oil exceeds the adsorptive capacity of the underlying soil and it reaches the water table, resulting in contaminated drinking and recreation water, petroleum vapour hazards in building air spaces and risk to utility lines. Three case histories are presented that involved substantial losses of petroleum products to the subsurface and notable environmental impacts. Detailed hydrogeologic investigations were conducted to delineate the nature and extent of contamination, including: liquid hydrocarbons on the surface of groundwater; dissolved hydrocarbons within groundwater; petroleum residue in soil; and hydrocarbon vapours in subsurface and nearby structures. Investigations typically involved air photographs, drilling of shallow probe holes, excavating bore or test holes and well/piezometers; field and laboratory analysis of petroleum constituents; and groundwater pumping tests. The case histories include a loss of gasoline from a service station in a large urban area, a bulk fuel distribution plant in a small community, and a former service station in a rural area. 9 figs

    Technological progress in petroleum exploration, production and processing requires a profound knowledge of the magnetic properties of the petroleum fluids. However, as far as we know there are not widely available constants of magnetic susceptibility for the majority of petroleum fluids. We have therefore measured the mass magnetic susceptibility (χ_m) of several petroleum fluids (such as crude oils, refined oil fractions, and formation waters) from local and worldwide sites. The magnetic features of natural reservoir petroleum fluids, together with fluids connected with the petroleum industry (such as drilling fluids etc.), fall into the following categories: diamagnetic solutions, paramagnetic suspensions and ferromagnetic "ferrofluid" suspensions. In the current investigations we have concentrated on the natural reservoir fluids, which are generally diamagnetic. There were distinct differences between the χ_m of the crude oils and the formation waters, with the oils having generally a more negative value of χ_m. The magnetic susceptibility of the oils appears to be related to their main physical and chemical properties, such as density, composition of group hydrocarbons, sulphur content and concentration of organometallic compounds. Low acidity and low sulphur oils have more negative values of χ_m. Light fractions of crude oil consisting mainly of paraffinic and naphtenic hydrocarbons are the most diamagnetic. The content of the less diamagnetic aromatics increases in the kerosene and gas oil fractions, and results in an increase in the magnetic susceptibility. Also, the magnetic susceptibility of the heavy oil fraction has a significantly higher χ_m than the light fractions, which appears to be connected with a higher concentration of paramagnetic components in the heavy fraction. The χ_m of the oil from various oil provinces were compared and found to be different. It seems that values of χ_m reflect specific features of the geological conditions for

    Recent advances in molecular biology have extended our understanding of the metabolic processes related to microbial transformation of petroleum hydrocarbons. The physiological responses of microorganisms to the presence of hydrocarbons, including cell surface alterations and adaptive mechanisms for uptake and efflux of these substrates, have been characterized. New molecular techniques have enhanced our ability to investigate the dynamics of microbial communities in petroleum-impacted ecosystems. By establishing conditions which maximize rates and extents of microbial growth, hydrocarbon access, and transformation, highly accelerated and bioreactor-based petroleum waste degradation processes have been implemented. Biofilters capable of removing and biodegrading volatile petroleum contaminants in air streams with short substrate-microbe contact times (emulsions to produce pipeline quality oil. There is interest in replacing physical oil desulfurization processes with biodesulfurization methods through promotion of selective sulfur removal without degradation of associated carbon moieties. However, since microbes require an environment containing some water, a two-phase oil-water system must be established to optimize contact between the microbes and the hydrocarbon, and such an emulsion is not easily created with viscous crude oil. This challenge may be circumvented by application of the technology to more refined gasoline and diesel substrates, where aqueous-hydrocarbon emulsions are more easily generated. Molecular approaches are being used to broaden the substrate specificity and increase the rates and extents of desulfurization. Bacterial processes are being commercialized for removal of H2S and sulfoxides from petrochemical waste streams. Microbes also have potential for use in removal of nitrogen from crude oil leading to reduced nitric oxide emissions provided that technical problems similar to those experienced in biodesulfurization can be solved.

    The focus on biodiesel research has shown a tremendous growth over the last few years. Several microbial and plant sources are being explored for the sustainable biodiesel production to replace the petroleum diesel. Conventional methods of biodiesel production have several limitations related to yield and quality, which led to development of new engineering strategies to improve the biodiesel production in plants, and microorganisms. Substantial progress in utilizing algae, yeast, and Escherichia coli for the renewable production of biodiesel feedstock via genetic engineering of fatty acid metabolic pathways has been reported in the past few years. However, in most of the cases, the successful commercialization of such engineering strategies for sustainable biodiesel production is yet to be seen. This paper systematically presents the drawbacks in the conventional methods for biodiesel production and an exhaustive review on the present status of research in genetic engineering strategies for production of biodiesel in plants, and microorganisms. Further, we summarize the technical challenges need to be tackled to make genetic engineering technology economically sustainable. Finally, the need and prospects of genetic engineering technology for the sustainable biodiesel production and the recommendations for the future research are discussed. PMID:25902752

    Full Text Available Nowadays, system developers are faced to produce complex, high quality software to support the demand for new and revised computer applications. This challenge is complicated by strict resource constraints, forcing management to deploy new technologies, methods and procedures to manage this increasingly complex environment. Often the methods, procedures and technologies are not integrated. Therefore, they achieve less than desired improvements in productivity, or force management to make tradeoff decisions between software quality and developer efficiency. Thus the production lines have to be developed faster, too. A very important role in this development is Software Engineering because many production processes are 'computer aided', so software has to be designed for this production system. It seems very important to do the software engineering right and fast.

    Full Text Available Concurrent engineering (CE is one of the widest known techniques for simultaneous planning of product and process design. In concurrent engineering, design processes are often complicated with multiple conflicting criteria and discrete sets of feasible alternatives. Thus multi-criteria decision making (MCDM techniques are integrated into CE to perform concurrent design. This paper proposes a design framework governed by MCDM technique, which are in conflict in the sense of competing for common resources to achieve variously different performance objectives such as financial, functional, environmental, etc. The Pareto MCDM model is applied to polyethylene pipe concurrent design governed by four criteria to determine the best alternative design to Pareto-compromise design.

    Directory of Open Access Journals (Sweden)

    Ibrahim S. Seddiek

    2015-03-01

    Full Text Available Modern marine power plants have been designed to improve the overall ship’s efficiency. This pushed the designers of marine machinery to search for unconventional fuels for these plants. During the previous years, diesel oil has been extensively used on-board ships. Due to the high price of light diesel oil and the environmental problems resulting from the use of heavy fuel oil, it has become necessary to search for an alternative to traditional fuels. As a result, natural gas fuel has been used on-board some types of ships, especially short-voyage cruise ships. Unfortunately, there are still some technical and logistic problems related to the use of natural gas as a fuel, especially as it is considered a non-renewable energy source. The use of hydrogen fuel on-board ships, particularly in modern power plants may contribute to overcoming the above problems. The present paper considers the possibility of the use of hydrogen fuel for marine applications and discusses different stages of hydrogen gas cycle beginning with hydrogen generation process from clean energy until using it as fuel for internal combustion engines on-board one RO/RO ship, named Taba, operating in the Mediterranean Sea. Compared to the diesel engine, the hydrogen fuelled engine is found to be lower in thermal efficiency and fuel consumption, however, some adjustments are needed.

    The present scenario of the INDEST Consortium among engineering, science and technology (including astronomy and astrophysics) libraries in India is discussed. The Indian National Digital Library in Engineering Sciences & Technology (INDEST) Consortium is a major initiative of the Ministry of Human Resource Development, Government of India. The INDEST Consortium provides access to 16 full text e-resources and 7 bibliographic databases for 166 institutions as members who are taking advantage of cost effective access to premier resources in engineering, science and technology, including astronomy and astrophysics. Member institutions can access over 6500 e-journals from 1092 publishers. Out of these, over 150 e-journals are exclusively for the astronomy and physics community. The current study also presents a comparative analysis of the key features of nine major services, viz. ACM Digital Library, ASCE Journals, ASME Journals, EBSCO Databases (Business Source Premier), Elsevier's Science Direct, Emerald Full Text, IEEE/IEE Electronic Library Online (IEL), ProQuest ABI/INFORM and Springer Verlag's Link. In this paper, the limitations of this consortium are also discussed.
