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

1992-01-01

During fiscal year 1992, the reserves generated $473 million in revenues, a $181 million decrease from the fiscal year 1991 revenues, primarily due to significant decreases in oil and natural gas prices. Total costs were $200 million, resulting in net cash flow of $273 million, compared with $454 million in fiscal year 1991. From 1976 through fiscal year 1992, the Naval Petroleum and Oil Shale Reserves generated more than $15 billion in revenues and a net operating income after costs of $12.5 billion. In fiscal year 1992, production at the Naval Petroleum Reserves at maximum efficient rates yielded 26 million barrels of crude oil, 119 billion cubic feet of natural gas, and 164 million gallons of natural gas liquids. From April to November 1992, senior managers from the Naval Petroleum and Oil Shale Reserves held a series of three workshops in Boulder, Colorado, in order to build a comprehensive Strategic Plan as required by Secretary of Energy Notice 25A-91. Other highlights are presented for the following: Naval Petroleum Reserve No. 1--production achievements, crude oil shipments to the strategic petroleum reserve, horizontal drilling, shallow oil zone gas injection project, environment and safety, and vanpool program; Naval Petroleum Reserve No. 2--new management and operating contractor and exploration drilling; Naval Petroleum Reserve No. 3--steamflood; Naval Oil Shale Reserves--protection program; and Tiger Team environmental assessment of the Naval Petroleum and Oil Shale Reserves in Colorado, Utah, and Wyoming

With an objective to establish an optimal method for utilizing coal liquefied oil, surveys were performed on the current status of applicable separation technologies for effective utilization of the hetero compounds of O and N contained in liquefied oil, the possibility of hetero compound utilization and issues in technological development for the utilization thereof. Since coal liquefied oil reflects greatly the coal composition and its structure, it contains generally a greater amount of hetero compounds, such as nitrogen and sulfur, as well as aromatic compounds than petroleum. If the hetero compounds could be removed from the liquefied oil more effectively before reforming as a result of progress in separation technologies, hydrogen consumption may be reduced. In addition, economic performance of the coal liquefaction business can be relatively improved by establishing a technology to utilize more effectively these by-products. The current fiscal year has performed surveys on the current status of technologies to separate oxygen and nitrogen in liquefied oil, the possibility of utilizing these hetero compounds, and issues in technological development for the utilization thereof. At the same time, surveys were carried out on the compositions, contents, and separation and analysis methods of hetero compounds in oil obtained by using the coal liquefaction systems being practically used.

Full Text Available Increased environmental awareness and depletion of resources are driving the industries to develop viable alternative fuels like vegetable oils, compresed natural gas, liquid petroleum gas, producer gas, and biogas in order to provide suitable substitute to diesel for compression ignition engine. 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.

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

The evaporation of crude oil and petroleum products

International Nuclear Information System (INIS)

Fingas, M. F.

1996-01-01

The physics of oil and petroleum evaporation was studied by means of an experimental apparatus. The evaporation was determined by weight loss and recorded on a computer. Examination of the data showed that most oil and petroleum products (those with seven to ten components) evaporate at a logarithmic rate with respect to time, while other petroleum products (those with fewer chemical components) evaporate at a rate which is square root with respect to time. Evaporation of oil and petroleum was not strictly boundary-layer regulated because the typical oil evaporation rate rates do not exceed that of molecular diffusion and thus turbulent diffusion does not increase the evaporation rates. Overall, boundary layer regulation can be ignored in the prediction of oil and petroleum evaporation. The simple equation relating only the logarithm of time (or the square root of time in the case of narrow-cut products) and temperature are sufficient to accurately describe oil evaporation. refs., figs

Advances in interpretive and analytical methods have opened the possibility to improve the existing Nordtest methodology for oil spill identification which was developed in 1991 under the Nordic Council of Ministers. In 2002, the European Committee for Standardization (CEN) established 2 working groups to revise the Nordtest Methodology into the following 2 CEN guidelines: (1) oil spill identification which includes waterborne and petroleum products, and (2) oil spill identification which in addition to including waterborne petroleum and petroleum products, includes analytical methodology and interpretation of results. The revised methodology includes a protocol/decision chart that has 3 tiered levels of analyses and data treatment. The methodology relies on the characterization of diagnostic ratios. The CEN working group intends to use the guidelines as a basis for a national oil spill identification protocol in each European country and for further international use. The methodology can be applied to oil samples of petrogenic origin with boiling points above 200 degrees C, such as crude oils, diesel fuel oils, residual bunker oils, lubricants, and mixtures of oily bilge and sludge samples. It is not intended for automotive gasolines or other light petroleum products. The method has been implemented in most forensic laboratories in Europe and has successfully differentiated between oils from a spill and possible pollution sources. 19 refs., 4 tabs., 10 figs.

Petroleum is produced by thermal decay of buried organic material over millions of years. Petroleum oilfield ecosystems represent resource of reduced carbon which favours microbial growth. Therefore, it is obvious that many microorganisms have adapted to harsh environmental conditions of these ecosystems specifically temperature, oxygen availability and pressure. Knowledge of microorganisms present in ecosystems of petroleum oil reservoirs; their physiological and biological properties help in successful exploration of petroleum. Understanding microbiology of petroleum oilfield(s) can be used to enhance oil recovery, as microorganisms in oil reservoirs produce various metabolites viz. gases, acids, solvents, biopolymers and biosurfactants. The aim of this review is to discuss characteristics of petroleum oil reservoirs. This review also provides an updated literature on microbial ecology of these extreme ecosystems including microbial origin as well as various types of microorganisms such as methanogens; iron, nitrate and sulphate reducing bacteria, and fermentative microbes present in petroleum oilfield ecosystems.

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

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

Estimating household fuel oil/kerosine, natural gas, and LPG prices by census region

Poyer, D.A.; Teotia, A.P.S.

1994-08-01

The purpose of this research is to estimate individual fuel prices within the residential sector. The data from four US Department of Energy, Energy Information Administration, residential energy consumption surveys were used to estimate the models. For a number of important fuel types - fuel oil, natural gas, and liquefied petroleum gas - the estimation presents a problem because these fuels are not used by all households. Estimates obtained by using only data in which observed fuel prices are present would be biased. A correction for this self-selection bias is needed for estimating prices of these fuels. A literature search identified no past studies on application of the selectivity model for estimating prices of residential fuel oil/kerosine, natural gas, and liquefied petroleum gas. This report describes selectivity models that utilize the Dubin/McFadden correction method for estimating prices of residential fuel oil/kerosine, natural gas, and liquefied petroleum gas in the Northeast, Midwest, South, and West census regions. Statistically significant explanatory variables are identified and discussed in each of the models. This new application of the selectivity model should be of interest to energy policy makers, researchers, and academicians

Oil-shale kerogen originated from resinous vegetation residues of past eras, whereas well petroleum was formed from oil shales by pressure and mild heat. Petroleum migrated to its present reservoir from neighboring oil-shale deposits, leaving a residue of black bituminous shales. The high carbon dioxide content of gases present in petroleum wells originated from kerogen, as it gives off carbon dioxide gas before producing soluble oil or bitumen.

Hydrothermal Liquefaction Biocrude Compositions Compared to Petroleum Crude and Shale Oil

Energy Technology Data Exchange (ETDEWEB)

Jarvis, Jacqueline M.; Billing, Justin M.; Hallen, Richard T.; Schmidt, Andrew J.; Schaub, Tanner M.

2017-02-17

We provide a direct and detailed comparison of the chemical composition of petroleum crude oil (from the Gulf of Mexico), shale oil, and three biocrudes (i.e., clean pine, microalgae Chlorella sp., and sewage sludge feedstocks) generated by hydrothermal liquefaction (HTL). Ultrahigh resolution Fourier transform ion cyclotron resonance mass spectrometry (FT-ICR MS) reveals that HTL biocrudes are compositionally more similar to shale oil than petroleum crude oil and that only a few heteroatom classes (e.g., N1, N2, N1O1, and O1) are common to organic sediment- and biomass-derived oils. All HTL biocrudes contain a diverse range of oxygen-containing compounds when compared to either petroleum crude or shale oil. Overall, petroleum crude and shale oil are compositionally dissimilar to HTL oils, and >85% of the elemental compositions identified within the positive-ion electrospray (ESI) mass spectra of the HTL biocrudes were not present in either the petroleum crude or shale oil (>43% for negative-ion ESI). Direct comparison of the heteroatom classes that are common to both organic sedimentand biomass-derived oils shows that HTL biocrudes generally contain species with both smaller core structures and a lower degree of alkylation relative to either the petroleum crude or the shale oil. Three-dimensional plots of carbon number versus molecular double bond equivalents (with observed abundance as the third dimension) for abundant molecular classes reveal the specific relationship of the composition of HTL biocrudes to petroleum and shale oils to inform the possible incorporation of these oils into refinery operations as a partial amendment to conventional petroleum feeds.

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)

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

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

Review of oil families and their petroleum systems of the Williston Basin

Science.gov (United States)

Lillis, Paul G.

2013-01-01

The petroleum system concept was first applied in 1974 (Dow/Williams) to identify three oil systems in the Williston Basin, and recent studies have expanded the number to at least nine. This paper reviews the petroleum geochemistry, oil-oil, and oil-source correlations of the oil systems of the Williston Basin, providing a new perspective and some new findings. Petroleum systems with a known source (documented oil-source correlation) include the Red River (Ordovician), Winnipegosis (Devonian), Bakken (Devonian-Mississippian), Madison (Mississippian), and Tyler (Pennsylvanian) systems. Petroleum systems with an identified source rock but no documented oil-source correlation are considered hypothetical and include the Winnipeg (Ordovician), Duperow (Devonian), and Birdbear (Devonian). The Deadwood (Cambrian-Ordovician) petroleum system is speculative because a good oil-prone source rock has not been identified. The stratigraphic distribution of the oil families from each system is generally limited to the same formation from which they were sourced due to efficient seals and a paucity of vertical migration pathways, but some notable exceptions do occur.

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.

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

Liquefied petroleum gas (LPG) is widely used in the Gaza Strip for domestic purposes, in agriculture and industry and, illegally, in cars. This study aimed to identify possible health effects on workers exposed to LPG in Gaza governorates. Data were collected by a questionnaire interview, and haematological and biochemical analyses of venous blood samples were made from 30 workers at filling and distribution stations and 30 apparently healthy controls. Statistically significant differences were found in all self-reported health-related complaints among LPG workers versus controls. LPG workers had significantly higher values of red blood cell counts, haemoglobin, haematocrit mean corpuscular haemoglobin and platelet counts. They also had significantly higher values of kidney function tests (urea, creatinine and uric acid) and liver function enzyme activities (aspartate aminotransferase and alanine aminotransferase). LPG workers at Gaza Strip petroleum stations are at higher risk for health-related symptoms and clinical abnormalities.

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

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

The efficiency of Bacillus subtilis DM-04 and Pseudomonas aeruginosa M and NM strains isolated from a petroleum contaminated soil sample from North-East India was compared for the biodegradation of crude petroleum-oil hydrocarbons in soil and shake flask study. These bacterial strains could utilize crude petroleum-oil hydrocarbons as sole source of carbon and energy. Bioaugmentation of TPH contaminated microcosm with P. aeruginosa M and NM consortia and B. subtilis strain showed a significant reduction of TPH levels in treated soil as compared to control soil at the end of experiment (120 d). P. aeruginosa strains were more efficient than B. subtilis strain in reducing the TPH content from the medium. The plate count technique indicated expressive growth and biosurfactant production by exogenously seeded bacteria in crude petroleum-oil rich soil. The results showed that B. subtilis DM-04 and P. aeruginosa M and NM strains could be effective for in situ bioremediation.

Evaluation of burn injuries related to liquefied petroleum gas.

Tarim, Mehmet Akin

2014-01-01

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

This paper describes the achievements in the Sunshine Project in fiscal 1990 on research of coal liquefying catalysts and a method for analyzing liquefied oil. Regenerating deteriorated hydrogenating catalysts for coal liquefied oil makes the restoration non-reversible because of residual sulfate. Discussions were given on the regenerating mechanisms. It was found that adding Ru enhances activity of an Ni-Mo catalyst for hydrogenating denitrification and hydrogenation. In studying coal liquefying reaction, a basic study was performed to analyze a catalytic mechanism in the hydrogenating decomposition. Sequential lightening reaction process is being analyzed at molecular levels on coal, preasphaltene, asphaltene and oil. Investigations were carried out on hydrogenating denitrification, deoxygenation, ring opening, decomposition mechanism and catalytic action. A study on precision structural analysis has begun on PSU circulating solvent as a NEDO bituminous coal liquefaction supporting technology. In fiscal 1990, a preliminary study was performed to identify the overall image of the composition of the Wandoan coal liquefied oil. Detailed analysis was executed on naphthalenes and their hydrides. This paper also describes composition analysis and reaction analysis by using the GC/MS ion chromatogram method.

This paper describes the achievements in the Sunshine Project in fiscal 1990 on research of coal liquefying reaction. The research contributes to developing a coal liquefaction technology as one of the methods for manufacturing clean energy and chemical raw materials from coal. In the fundamental study on the liquefaction, primarily liquefied heavy constituents in different types of coals were divided into such constituents as HI, TI, and THFI to discuss the performance and coking behavior of each constituent as solvent. Furthermore, effects of hydrogenation treatment were also elucidated. Decomposing reaction was performed on different heavy products to discuss effects of the reaction conditions. In the liquefying reaction using petroleum-based heavy oil as solvent, different shale oils were used in experiments for comparison with the case of using tar sand bitumen. In the study of reforming the product, comparison was carried out on reactions in hydrogenation treatment and contact decomposition of medium to heavy fractions of liquefied oil. A separation experiment was made on hetero compounds by means of solvent extraction and pressure crystallization of liquefied oil naphtha and light oil fraction. Effects of additive were investigated in an engine test on the stabilized and balanced light oil fraction. Discussions were given on high level utilization of heat treated oil recovered from residues in liquefaction distillation. (NEDO)

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

Petroleum imports account for the largest share of the US trade deficit. Over one-third of the 1996 merchandise trade deficit is attributed to imported oil. The good news is that substantial domestic oil resources, both existing and yet-to-be-discovered, can be recovered using advanced petroleum technologies. The Energy Information Agency estimates that advanced technologies can yield 10 billion additional barrels, equal to $240 billion in import offsets. The US Department of Energy`s National Petroleum Technology Office works with industry to develop advanced petroleum technologies and to transfer successful technologies to domestic oil producers. This publication shows the locations of these important technology development efforts and lists DOE`s partners in this critical venture. The National Petroleum Technology Office has 369 active technology development projects grouped into six product lines: Advanced Diagnostics and Imaging Systems; Advanced Drilling, Completion, and Stimulation; Reservoir Life Extension and Management; Emerging Processing Technology Applications; Effective Environmental Protection; and Crosscutting Program Areas.

Full Text Available Some physical and chemical properties of samples of light, medium and heavy Nigerian crude oils and petroleum products including gasoline, kerosene and engine oil have been measured and are reported in this paper. The crude oils and petroleum products have also been characterized by fractional distillation and elution liquid chromatography. The fractions obtained from elution liquid chromatography were analyzed using gas chromatography (GC. The GC fractions were identified by comparing the retention time of peaks in the unknown samples with those of components of calibration standard mixtures. The importance of the physico-chemical properties and the significance of the fractional distillation and chromatographic separation methods to industrial process operations have been discussed.

This paper describes the achievements in the Sunshine Project in fiscal 1991 on research of coal liquefying catalysts and a method for analyzing liquefied oil. Alkalis and alkali earth metals present during coal liquefied oil hydrogenation treatment deteriorate the activity remarkably as an effect of metal deposition from an Mo-based catalyst on the activity deterioration. Discussions were given on hydrogenating decomposition paths for bi-cyclic compounds by using reaction of model substances. Preliminary discussions were given jointly under the Japanese and Canadian technical cooperation on enhancing the quality of co-treated oil in the coal liquefaction, and on catalysts used therein. A 1-t/d PSU circulating solvent was studied to support the NEDO's bituminous coal liquefaction program. Analyses were carried out on acenaphthenes, biphenyls, phenanthrenes, and anthracenes in the oil liquefied from Wandoan coal. Discussions were given on CoMo/Al{sub 2}O{sub 3} on the effects of catalyst concentrations and particle sizes in the coal liquefying reaction. In order to elucidate different non-covalently bonded high-order structures of coal polymer assemblies, chemical treatment was applied to coals under a relatively mild condition (room temperature to 150 degrees C). Chemical structures as a result of the non-covalent bond in the coals were investigated from change due to the treatment in the pyridine extraction characteristics. (NEDO)

China's new oil import status underpins world's most dynamic petroleum scene

International Nuclear Information System (INIS)

Anon.

1994-01-01

China is poised to become a net importer of oil in 1994--95. That sets the stage for China importing more than 1 million b/d of crude oil and refined products on a net basis by the turn of the century. That development underpins a bigger story -- arguably the biggest story on the petroleum scene today. The turnabout that is seeing the world's fifth biggest oil producer go from significant oil exporter in recent years to major oil importer by the turn of the century points to several other truisms in the petroleum industry: That an oil demand surge in the Asia-Pacific region led by China will fuel overall world oil demand growth for years to come; that a refining and petrochemical boom in a country that accounts for about one fifth of the world's population has dramatic implications for those two industries; that privatization has gathered so much momentum in the global petroleum industry that even Communist China has embraced some form of it; that China's domestic crude supply shortfall is creating unprecedented opportunities for foreign upstream investors in one of the world's most prospective yet underexplored and underexploited regions; and that the same new openness that is distinguishing China's petroleum industry today is turning some of its state owned companies into major competitors to be reckoned with on the international scene, upstream and downstream. The paper discusses China's oil export/import balance, supply/demand outlook, policy changes, and new regulations governing export of crude oil and products

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

Dewaxing hydrocarbon oils. [British patent

Energy Technology Data Exchange (ETDEWEB)

1933-06-23

In dewaxing hydrocarbon oils such as residium stocks, overhead distillates and crude petroleum or shale oils, by admixing with a liquefied normally gaseous solvent, such as liquefied propane, and cooling to crystallize the wax, the rate of crystallization diminishes rapidly when a certain temperature in an example about 20/sup 0/F is reached. The diminution is prevented during further cooling by removing solvent by evaporation at such a rate that the proporation of solvent in the oil solvent component is maintained at about that existing at the temperature at which the alteration in the rate of crystallization takes place. The evaporation is effected by adjusting the pressure on the mixture, preferably in stages. Solvents for coloring matters and asphaltic compounds, such as carbon disulfide sulfur dioxide, methyl chloride or butyl alcohol may be added to the mixture before crystallization. Chilled solvent may be added to the chilled mixture before separation of the wax in a centrifuge, in order to increase the difference in specific gravity between the wax and the oil-solvent component.

Toxicity of oils and petroleum hydrocarbons to estuarine crustaceans

1978-04-01

Bioassay experiments with various life stages of three estuarine shrimp and soluble petroleum hydrocarbons (PH) revealed residual Bunker C oil and refined No. 2 fuel oil to be more toxic than two crude oils tested. Larvae of Palaemonetes pugio were slightly more sensitive to the PH than adults, while young penaeid shrimp were shown to be more resistant than older, larger individuals. Shrimp exposed to PH in conjunction with temperature and salinity changes were more susceptible to the PH. Some common aromatic and diaromatic PH, including three naphthalene compounds, were utilized in bioassays. Naphthalenes were highly toxic. The toxicity of petroleum products is closely related to aromatic hydrocarbon content, especially the naphthalenes and related hydrocarbons.

Planning and scheduling for petroleum refineries using mathematical programming

Directory of Open Access Journals (Sweden)

Joly M.

2002-01-01

Full Text Available The objective of this paper is the development and solution of nonlinear and mixed-integer (MIP optimization models for real-world planning and scheduling problems in petroleum refineries. Firstly, we present a nonlinear planning model that represents a general refinery topology and allows implementation of nonlinear process models as well as blending relations. The optimization model is able to define new operating points, thus increasing the production of the more valuable products and simultaneously satisfying all specification constraints. The second part addresses scheduling problems in oil refineries, which are formulated as MIP optimization models and rely on both continuous and discrete time representations. Three practical applications closely related to the current refinery scenario are presented. The first one addresses the problem of crude oil inventory management of a refinery that receives several types of crude oil delivered exclusively by a single oil pipeline. Subsequently, two optimization models intended to define the optimal production policy, inventory control and distribution are proposed and solved for the fuel oil and asphalt plant. Finally, the planning model of Moro et al. (1998 is extended in order to sequence decisions at the scheduling level in the liquefied petroleum gas (LPG area for maximization of the production of petrochemical-grade propane and product delivery.

Will the 21. century be the petroleum challenge century? The petroleum problem is no longer the affair of experts and journalists, it challenges also governments and consumers in pressing terms. If there is today a petroleum problem, there is no oil or gas shortage for the moment. The cumulated oil and gas reserves would allow to face the demand of the century, with the condition that investments in exploration, field development, production, and back-end of oil and gas industries will be done in time. This book, written by specialists of energy economics and geopolitics shows up some of the key questions of our energy future. In particular, it invites us to never forget the basic heavy trends of the hydrocarbons sector in order to never be trapped by superficial extrapolations of short term phenomena. Content: heavy trend of oil prices at the 2020 prospects, natural gas take over?; oil and gas geopolitics: enough of hydrocarbons for the 21. century; Russia and Caspian sea oil and gas weight; China: a new strategic actor of the energy scene; influence of 'futures' market, of speculation, and of stocks on hydrocarbon prices; which future for LNG?; natural gas in the USA: towards a new foreign dependence.

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

Petroleum refineries around the world have adopted different technological options to manage the solid wastes generated during the refining process and stocking of crude oil. These include physical, chemical and biological treatment methods. In this investigation bacterial mediated oil separation is effected. Two strains of Bacillus were isolated from petroleum-contaminated soils, and inoculated into slurry of sludge, and sludge-sand combinations. The bacteria could effect the separation of oil so as to form a floating scum within 48h with an efficiency of 97% at < or =5% level of sludge in the sludge-sand mixture. The activity was traced to the production of biosurfactants by bacteria.

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

Soybean oil is an abundant and renewable resource through annual crop production. The replacement of paraffin oil with soybean oil in agricultural adjuvants would create an additional market for surplus soybeans and help alleviate dependence on non-renewable petroleum oil. Field and laboratory experiments were conducted to compare effects of a petroleum oil-emulsifier blend (POC) and a soybean oil-emulsifier blend (SBOC) as adjuvants for postemergence herbicides. In field experiments, little difference was observed between POC and SBOC in the ability to enhance control of velvetleaf (Abutilon theophrasti Medik.) with 0.6 or 1.1 kg/ha bentazon [3-(1-methylethyl)-(1H)-2,1,3-benzothiadiazin-4(3H)-one 2,2-dioxide]. Control of giant foxtail (Setaria faberi Herrm.) with 0.1 kg/ha sethoxydim {2-[1-(ethoxyimino)butyl]-5-[2-(ethylthio)propyl]-3-hydroxy-2-cyclohexen-1-one} was enhanced more by POC than by SBOC. The effects of adjuvants and relative humidity (RH) on absorption, translocation, and metabolism of the methyl ester of 14 C-haloxyfop {2-[4-[[3-chloro-5-(trifluoromethyl)-2-pyridinyl]oxy]phenoxy]propanoic acid} in corn (Zea mays L.) were investigated. Addition of 1.0% (v/v) POC to the treatment solution resulted in greater foliar absorption and translocation of 14 C than addition of 1.0% (v/v) SBOC

The aim of this research is the production of polyurethane (PU) foams with biopolyols from liquefied oil palm mesocarp fibre (OPMF) and renewable monomer. Liquefaction of OPMF was studied using polyhydric alcohol (PA) which is PEG-400 as liquefaction solvents in conventional glass flask. In the second part of this paper was obtained the PU foams which presented good results when compared with commercial foams and include polyols from of fossil fuels. PU foams were prepared by mixing liquefied OPMF biopolyol, renewable monomer from waste cooking, additives and methylene diphenyl diisocyanate (MDI). Water was used as an environmental friendly blowing agent. The factors that influence the cell structure of foams (i.e., catalyst, surfactant, dosage of blowing agent, and mass ratio of biopolyol to renewable monomer were studied. The synthesized PU foams were characterized by FTIR and SEM. The formulation of the PU foams should be improved, but the results show that is possible the use biopolyols and renewable monomer to produce industrial foams with lower cost.

This paper summarizes the results from the project 'Vision of the Key Petroleum Refining Technologies for China National Petroleum Co. (CNPC) in the Early 21st Century' undertaken by the Department of R and D Administration, CNPC, and its affiliate key laboratory, The Key Laboratory of Catalysis operated by China University of Petroleum, Beijing. The objective of the project was to identify the challenges and opportunities of CNPC's petroleum refining business given increasing economy globalization and stricter environmental regulations. Using the modified Delphi method, four key technologies for CNPC's oil refining industry were identified. They are: integrated fluid catalytic cracking (FCC), hydroprocessing, residue hydrocracking, and high-grade lubricant production. The most significant technology will be the integrated FCC technology that can economically increase the yield of light fractions as well as upgrade transportation fuels. In China, FCC units produce about 80% and 30% commercial gasoline and diesel, respectively. To ensure compliance with future environmental legislation, hydroprocessing technologies, including those related to petroleum product hydrorefining and distillate hydrocracking, should be developed. By combining residue hydrocracking and FCC technologies, poorer quality residua can be processed. Supplying high-grade lube oils is one of the main tasks for CNPC's oil refining industry. Development of hydrodewaxing technologies to manufacture API group II/III base oil is the main direction for CNPC's lubricant production business

The method of purification of waste water of NPS from petroleum oil using UV-radiation

International Nuclear Information System (INIS)

Kulemin, V.V.; Kareta, V.I.

1993-01-01

The main methods of concentration and purification of radioactive waste water of russian NPS are distillation and ion exchange. When waste water containing petroleum oil and washing matter is distillated, part of petroleum and washing matters go to the condensate. The purification of this condensate leads to pollution of ion exchange resins by petroleum oil and reduction of the filter cycle number. The purification of condensate of Russian NPS from petroleum oil is carried out using active carbon and polymer filters, but this process is not effective and fails to give pure condensate. Therefore, the authors began to search for more effective methods of purification of waste water from petroleum oil. They found that UV-radiation makes it possible to purify water from petroleum matter to concentration of the organic phase less than 0.5 mg/dm3. In this process of purification the air, contained in the water phase, was used as an oxidant. When purification is carried out in the absence of sorbents, the quantity of radioactive solid waste, which have to be recovered, decreases. During the study of purification of waste water it was found that increasing of the temperature of the process increases the rate of UV-radiation-induced oxidation of organic phase. The increase in the initial concentration of petroleum products also increases the rate of petroleum oil decomposition. The content of ions in water phase decreases the purification rate. The investigations were carried out on the laboratory scale with water and condensate from Tver's NPS

Toxicology of oil field wastes. Hazards to livestock associated with the petroleum industry.

Science.gov (United States)

Edwards, W C

1989-07-01

In oil-producing states, the proximity of livestock to drilling operations and production sites often results in poisoning of animals from ingestion of crude oil, condensate, salt water, heavy metals, and caustic chemicals. The heavy metals encountered most frequently are lead from pipe joint compound and arsenicals and chromates used as corrosion inhibitors. Numerous toxic and caustic chemicals are used in drilling muds and fluids. Crude oil and salt water spills are common occurrences around production sites. Pipeline breaks may result in exposure of livestock to crude oil or refined petroleum hydrocarbons. Ingestion of petroleum hydrocarbons may result in sudden death from peracute bloat. The most common cause of illness or death following exposure to petroleum hydrocarbons is aspiration pneumonia, which may cause a chronic progressive deterioration of health, with death after several days or weeks. Cases in which livestock are exposed to oil, salt water, or caustic chemicals, but do not die acutely or from aspiration pneumonia are more frustrating to diagnose. In these cases, parasitism, poor nutrition, and other debilitating diseases must be considered. Anorexia, weight loss, and decreased rumen motility may be caused by a disruption of normal rumen function. Petroleum hydrocarbons, salt water, and caustic chemicals have the potential of altering rumen flora and enzymatic processes as well as damaging the ruminal and gastrointestinal epithelium. The toxicity of petroleum hydrocarbons appears to be related more closely to the volatility and viscosity of the product than to other factors. The more volatile straight chain and aromatic petroleum hydrocarbons have a greater potential for aspiration pneumonia and may produce an anesthetic-like action if absorbed systemically. The more volatile petroleum hydrocarbons also are more irritating to skin and mucous membranes and appear to be more damaging to rumen flora. Treatment of petroleum hydrocarbon ingestion is

Highlights: Black-Right-Pointing-Pointer Microalgae are able to physiological acclimatization low doses of petroleum and diesel oil. Black-Right-Pointing-Pointer When petroleum or oil concentration exceeds these limits, survival depend of rare mutations. Black-Right-Pointing-Pointer Petroleum-resistant and diesel oil mutants occur spontaneously prior to oil exposure. Black-Right-Pointing-Pointer After 300 generations of artificial selection resistant strains were obtained. Black-Right-Pointing-Pointer Cyanobacteria has more difficulties to achieve petroleum resistance than Chlorophyta. - Abstract: There is increasing scientific interest in how phytoplankton reacts to petroleum contamination, since crude oil and its derivatives are generating extensive contamination of aquatic environments. However, toxic effects of short-term petroleum exposure are more widely known than the adaptation of phytoplankton to long-term petroleum exposure. An analysis of short-term and long-term effects of petroleum exposure was done using experimental populations of freshwater (Scenedesmus intermedius and Microcystis aeruginosa) and marine (Dunaliella tertiolecta) microalgae isolated from pristine sites without crude oil product contamination. These strains were exposed to increased levels of petroleum and diesel oil. Short-term exposure to petroleum or diesel oil revealed a rapid inhibition of photosynthetic performance and cell proliferation in freshwater and marine phytoplankton species. A broad degree of inter-specific variation in lethal contamination level was observed. When different strains were exposed to petroleum or diesel oil over the long-term, the cultures showed massive destruction of the sensitive cells. Nonetheless, after further incubation, some cultures were able to grow again due to cells that were resistant to the toxins. By means of a fluctuation analysis, discrimination between cells that had become resistant due to physiological acclimatization and resistant

Highlights: ► Microalgae are able to physiological acclimatization low doses of petroleum and diesel oil. ► When petroleum or oil concentration exceeds these limits, survival depend of rare mutations. ► Petroleum-resistant and diesel oil mutants occur spontaneously prior to oil exposure. ► After 300 generations of artificial selection resistant strains were obtained. ► Cyanobacteria has more difficulties to achieve petroleum resistance than Chlorophyta. - Abstract: There is increasing scientific interest in how phytoplankton reacts to petroleum contamination, since crude oil and its derivatives are generating extensive contamination of aquatic environments. However, toxic effects of short-term petroleum exposure are more widely known than the adaptation of phytoplankton to long-term petroleum exposure. An analysis of short-term and long-term effects of petroleum exposure was done using experimental populations of freshwater (Scenedesmus intermedius and Microcystis aeruginosa) and marine (Dunaliella tertiolecta) microalgae isolated from pristine sites without crude oil product contamination. These strains were exposed to increased levels of petroleum and diesel oil. Short-term exposure to petroleum or diesel oil revealed a rapid inhibition of photosynthetic performance and cell proliferation in freshwater and marine phytoplankton species. A broad degree of inter-specific variation in lethal contamination level was observed. When different strains were exposed to petroleum or diesel oil over the long-term, the cultures showed massive destruction of the sensitive cells. Nonetheless, after further incubation, some cultures were able to grow again due to cells that were resistant to the toxins. By means of a fluctuation analysis, discrimination between cells that had become resistant due to physiological acclimatization and resistant cells arising from rare spontaneous mutations was accomplished. In addition, an analysis was done as to the maximum capacity of

Trinidad and Tobago's petroleum sector remains at a crossroads. While heavily reliant on oil and gas for domestic energy consumption and hard currency export earnings, the small Caribbean island nation faces some tough choices in reviving its hydrocarbon sector in the 1990s. Exploration and production of crude oil have stagnated in recent years, and domestic refinery utilization remains low at 36%. However, substantial natural gas reserves in Trinidad and Tobago offer the promise of a burgeoning natural gas based economy with an eye to liquefied natural gas and gas based petrochemical exports. Any solutions will involve considerable outlays by the government as well as a sizable infusion of capital by foreign companies. Therein lie some of the hard choices. The article describes the roles of oil and gas, foreign investment prospects, refining status, refining problems, gas sector foreign investment, and outlook for the rest of the 1990's

Spillage of petroleum hydrocarbons causes significant environmental pollution. Bioremediation is an effective process to remediate petroleum oil contaminant from the ecosystem. The aim of the present study was to reclaim a petroleum oil-contaminated soil which was unsuitable for the cultivation of crop plants by using petroleum oil hydrocarbon-degrading microbial consortium. Bacterial consortium consisting of Bacillus subtilis DM-04 and Pseudomonas aeruginosa M and NM strains were seeded to 20% (v/w) petroleum oil-contaminated soil, and bioremediation experiment was carried out for 180 days under laboratory condition. The kinetics of hydrocarbon degradation was analyzed using biochemical and gas chromatographic (GC) techniques. The ecotoxicity of the elutriates obtained from petroleum oil-contaminated soil before and post-treatment with microbial consortium was tested on germination and growth of Bengal gram (Cicer aretinum) and green gram (Phaseolus mungo) seeds. Bacterial consortium showed a significant reduction in total petroleum hydrocarbon level in contaminated soil (76% degradation) as compared to the control soil (3.6% degradation) 180 days post-inoculation. The GC analysis confirmed that bacterial consortium was more effective in degrading the alkane fraction compared to aromatic fraction of crude petroleum oil hydrocarbons in soil. The nitrogen, sulfur, and oxygen compounds fraction was least degraded. The reclaimed soil supported the germination and growth of crop plants (C. aretinum and P. mungo). In contrast, seeds could not be germinated in petroleum oil-contaminated soil. The present study reinforces the application of bacterial consortium rather than individual bacterium for the effective bioremediation and reclamation of soil contaminated with petroleum oil.

Will Venezuelan extra-heavy oil be a significant source of petroleum in the next decades?

International Nuclear Information System (INIS)

Sena, Marcelo Fonseca Monteiro de; Rosa, Luiz Pinguelli; Szklo, Alexandre

2013-01-01

Unconventional oil resources are needed to complement petroleum supply in the next decades. However, given the restrictions that pertain to the production of these resources, this article evaluates the availability of Venezuelan unconventional oil for helping meet the future worldwide petroleum demand. Venezuela has the world's second-largest oil reserves, but the majority of it is unconventional extra-heavy oil from the Orinoco Oil Belt. The perspective of Venezuelan production, the ways in which PDVSA, the state oil company, will raise funds for planned investments and the future oil price predictions are used to assess Venezuela's ability to serve as a source of unconventional oil in the coming years. Findings indicate that Venezuelan crude oil will be increasingly able to provide part of the marginal petroleum supply at a level predicted in global scenarios but short of that predicted by the country's government. Operational difficulties and the effort to raise financial resources for the oil production in the Belt require urgency in overcoming difficulties. As conventional production in Venezuela will stabilise in the coming years and the country is dependent on oil production, Venezuela will rely on extra-heavy oil extraction to ensure increased oil production and the stabilisation of internal accounts. - Highlights: • We analyse the future unconventional oil production capacity of Venezuela. • The study is based on operational capacity, investments capacity and future prices. • The study indicates a production shorter than that predicted by the Venezuelan government. • Venezuela can provide part of the marginal petroleum supply in the coming years

2008-07-01

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

Yang, C.; Wang, Z.; Hollebone, B.; Brown, C.E.; Landriault, M.

2008-01-01

A study was conducted in which sesquiterpanes, a component of crude oils and petroleum products, were identified and characterized in an effort to determine the feasibility of using them as biomarkers for fingerprinting and identifying unknown lighter petroleum product spills. The study compared the distributions of sesquiterpanes in different oils, oil distillation fractions and refined products, including light and mid-range distillate fuels, residual fuels and lubricating oils. Evaporative weathering effects on sesquiterpane distribution and concentration were quantitatively studied and several diagnostic indices of sesquiterpane were developed for oil correlation and differentiation. Bicyclic sesquiterpanes in crude oils and oil products have much different abundances and distributions. Therefore, the relevant sesquiterpane ratios are different. Bicyclic sesquiterpanes are mostly partitioned into the medium distillation fractions. The study showed that concentrations of sesquiterpanes in crude oil and diesel fuel increase in proportion with the increase of weathering percentages. Relevant diagnostic ratios therefore remained stable. It was concluded that C 15 and C 16 sesquiterpanes may be alternative internal tracers to provide a direct way to estimate the depletion of oils, particularly diesels, in oil spill investigations. 13 refs., 6 tabs., 4 figs

This paper reported on a study that presented a preliminary quantitative chemical characterization of Alberta oil sands and many other related Alberta oils such as oil sand bitumen, Cold Lake bitumen, Albian heavy synthetic crude, and Alberta Mixed sweet blend. The rapid increase in production of the Alberta oil sands has resulted in unprecedented environmental concern. The mining, extraction and production of oil sands such resulted in huge consumption of water resources, huge emission of greenhouse gas and large number of tailings ponds. In addition, accidental spills in the transportation and usage of oil sands will potentially cause considerable impact on the environment. It is therefore essential to have the ability to characterize Alberta oil sands and their oil products. The specific chemical properties of the oil sands bitumen must be known. Therefore, this study collected quantitative data on the concentration and distribution profiles of target compounds in Alberta oil sands and its petroleum products. The chemical fingerprints of 5 Alberta oil sands and their related petroleum products were studied using gas chromatography/flame ionization detection (GC/FID) and gas chromatography/mass spectrometry (GC/MS). The characterized hydrocarbons were n-alkanes; target alkylated PAHs and other EPA priority PAHs; biomarker terpanes and steranes; and bicyclic sesquiterpanes. The information acquired during this study will provide the basis for oil-oil correlation and differentiation in future environmental applications relevant to oil sands. 24 refs., 6 tabs., 4 figs.

Biological markers or biomarkers are complex molecules originating from formerly living organisms. They are among the most important hydrocarbon groups in petroleum because every crude oil exhibits an essentially unique biomarker or fingerprint due to the wide variety of geological conditions under which oil is formed. When found in crude oils, rocks and sediments, biomarkers have the same structures as their parent organic molecules. Therefore, chemical analysis of source-characteristic and environmentally persistent biomarkers can provide valuable information in determining the source of spilled oil. Biomarkers can also be used to differentiate oils and to monitor the degradation process and the weathering state of oils under a range of conditions. The use of biomarker techniques to study oil spills has increased significantly in recent years. This paper provided case studies to demonstrate: (1) biomarker distribution in weathered oil and in petroleum products with similar chromatographic profiles, (2) sesquiterpenes and diamondoid biomarkers in oils and light petroleum products, (3) unique biomarker compounds in oils, (4) diagnostic ratios of biomarkers, and (5) biodegradation of biomarkers. It was noted that the trend to use biomarkers to study oil spills will continue. Continuous advances in analytical methods will further improve the application of oil hydrocarbon fingerprinting for environmental studies. 36 refs., 5 tabs., 12 figs

Co-Processing refers to the combined processing of coal and petroleum-derived heavy oil feedstocks. The coal feedstocks used are those typically utilized in direct coal liquefaction: bituminous, subbituminous, and lignites. Petroleum-derived oil, is typically a petroleum residuum, containing at least 70 W% material boiling above 525{degrees}C. The combined coal and oil feedstocks are processed simultaneously with the dual objective of liquefying the coal and upgrading the petroleum-derived residuum to lower boiling (<525{degrees}C) premium products. HTI`s investigation of the Co-Processing technology has included work performed in laboratory, bench and PDU scale operations. The concept of co-processing technology is quite simple and a natural outgrowth of the work done with direct coal liquefaction. A 36 month program to evaluate new process concepts in coal-oil coprocessing at the bench-scale was begun in September 1994 and runs until September 1997. Included in this continuous bench-scale program are provisions to examine new improvements in areas such as: interstage product separation, feedstock concentrations (coal/oil), improved supported/dispersed catalysts, optimization of reactor temperature sequencing, and in-line hydrotreating. This does not preclude other ideas from DOE contracts and other sources that can lead to improved product quality and economics. This research work has led to important findings which significantly increased liquid yields, improved product quality, and improved process economics.

In this work the aplication in the oil industry of the technique of radioactive tracer appears for the detection of internal leaks in a submarine duct that gives service as it lines of receipt of liquefied petroleum gas (Gas LP) located in the Mexican coast of the Pacific Ocean. This system of marine pipe is a consistent arrangement of a duct interior of 0.254 m (10 inches) of nominal diameter (N.D.) of steel to the carbon for cryogenic service ASTM A 333, Grade 6, schedule 30, isolated thermally with foam of polyurethane and shielding in a steel tube to the carbon ASTM A 53 Grade A, of 0.508 m (20 inches) N. D., schedule 20, which is recovered by a ballast encircling of concrete of 0.0508 m (2 inches) of thickness, reinforced with mesh metallic, and that 1315 m runs on the marine stratum to a maximum depth of 12.5 m. For the detection of leaks by radiotracer it was used as tracer the radioactive isotope La-140 produced in the TRIGA Mark III Experimental Reactor of the National Institute of Nuclear Research, starting from stable lanthanum nitrate (La(NO 3 ) 3 6H 2 O), with an activity of 100 mCi, the one which after having been made logistics tasks, given very particular sea maneuvers and due to the conditions of the work place, in the interior tube was injected in two subsequent stages to cover both duct senses; from earth and from the marine end respectively, there being used fresh water like transport way and submergible sodium iodide detectors (NaI) for the rake of the La-140. At the end of the journeys of pursuit of the radiotracer, it was determine the presence of three leaks points located in the break area of the marine surf to 360 m, 450 m and 495 m of distance of a reference point located in the beach section named Trap of Devils.

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

This paper describes the achievements in the Sunshine Project in fiscal 1992 on research of coal liquefying catalysts and a method for analyzing liquefied oil. Oxidative regeneration was performed on an Ni-W based waste catalyst used in reforming (hydrogenating) coal liquefied light oil fraction. If the regeneration can be done with low oxygen partial pressure and step-wise temperature rise, the activity after the regeneration can be restored to the level of a new catalyst, with sulfate production being suppressed. Model reaction was discussed by changing the amount of W and Mo carried by alumina. Suppressing the carrying amount can control the hydrogenation activity and the hydrogenating decomposition activity. Comparison was given on compositions of woods and such hydrogenation products as peat and coal. Analysis was performed on composition of the circulating solvent used in the NEDO bituminous coal liquefying PSU. In the initial stage of the operation, the solvent had higher concentrations in the groups of compounds not having alkyl groups, and compounds having the alkyl groups increased in the end of the operation. Discussions were given also on index materials to control the operation of solvent hydrogenating process. Efficient preparation conditions were discussed on an iron sulfide particulate catalyst that utilizes surface reaction of a solid metal while mechanical impact such as vibration is being given. Effects of the catalyst concentration in coal liquefaction were experimented by using oil soluble molybdenum, wherein no change was found in the reaction mechanism. (NEDO)

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

Diamondoids are a class of saturated hydrocarbons that consist of 3-dimensionally fused cyclohexane rings. Diamondoid compounds in petroleum are the result of carbonium ion rearrangements of cyclic precursors on clay superacids in the source rock during oil generation. They are considered to be a problem due to their deposition during production of reservoir fluids and transportation of natural gas, gas condensates and light crude oils. At high concentrations, and with changes in pressure and temperature, diamondoid compounds can segregate out of reservoir fluids during production. Environmental scientists have considered fingerprinting the diamondoid hydrocarbons as a forensic method for oil spill studies. Since diamondoid compounds are thermodynamically stable, they have potential applications in oil-source correlation and differentiation for cases where traditional biomarker terpanes and steranes are absent because of environmental weathering or refining of petroleum products. Although there is increased awareness of possible use of diamondoid compounds for source identification, there is no systematic approach for using these compounds. Quantitative surveys of the abundances of diamondoids are not available. Therefore, this study developed a reliable analytical method for quantitative diamondoid analysis. Gas chromatography/mass spectrometry (GC/MS) was used to quantitatively determine diamondoid compounds (adamantane, diamantane and their alkylated homologues) in 14 fresh crude oils and 23 refined petroleum products, including light and mid-range distillate fuels, residual fuels and lubricating oils collected from different sources. Results were compared with 2 types of biomarker compounds in oil saturated hydrocarbon fractions. Several diagnostic ratios of diamondoids were developed based on their concentrations. Their potential use for forensic oil spill source identification was evaluated. 24 refs., 8 tabs., 4 figs

The exceptional chemical and physical properties of nanostructured materials are extremely suitable for designing new and enhanced sensing devices, particularly gas sensors and biosensors. The present work describes the synthesis of magnesium oxide (MgO) nanoparticles through two methods: a green synthesis using aloe vera plant extract and a chemical method using a glycine-based solution combustion route. In a single step, the extracted organic molecules from aloe vera plants were used to reduce metal ions by the green method. MgO nanoparticles were coated onto the interdigital electrode using the drop-drying method. The dynamic gas-sensing characteristics were measured for liquefied petroleum gas (LPG) at different concentrations and various temperatures. The MgO nanoparticles were characterized by using x-ray diffraction, field emission scanning electron microscopy, and high-resolution transmission electron microscopy to determine the size and structure of the particles. The product's functional properties were analyzed by Fourier transform-infrared spectroscopy and UV-visible spectroscopy. We found that the LPG sensing behavior of biologically synthesized MgO registers excellent sensitivity at various operating temperatures.

Opportunities and Challenges for Petroleum and LPG Markets in Sub-Saharan Africa

International Nuclear Information System (INIS)

Matthews, William G.

2014-01-01

Petroleum products are the lifeblood of the economies of all Sub-Saharan African countries. They are key fuels used in road transport and power generation. Households use kerosene and liquefied petroleum gas (LPG) for lighting and cooking. In this era of high oil prices, if the product is state-subsidized, the government budget bears the brunt of price increases. If the price changes are passed through to consumers, the household budgets are impacted directly. The countries most vulnerable to oil price shocks are the low-income oil importers which are disproportionately concentrated in Sub-Saharan Africa. End user prices are affected by several factors: market size and economies of scale, mode of product transport, controlled pricing, protection of inefficient domestic suppliers, degree of competition, clear and stable legal framework, effective monitoring and disclosure of industry statistics. This paper is based on two recent studies of the oil sectors of several countries in Sub-Saharan Africa which posed the following questions: Is each stage in the supply chain, from import of crude oil or refined products to retail, efficiently run and are the efficiency gains passed on to end-users? If not, what are the potential causes and possible means of remedying the problems? - Highlights: • Examines comparative efficiencies of oil product supply chains in twelve sub-Saharan countries. • Identifies areas for improvement towards “best practice”. • Objective is to reduce differential between international reference prices and consumer prices

Balaeam base oil was chosen as a model oil in the present study through which some abiotic treatments were implemented aiming at attenuating its naphthenic and aromatic contents; such as the adsorptive technique and the gamma-irradiation technique . In an attempt to apply the biodegrading bacteria as oil pollutant bio indicators upon coastal water samples, a correlation between hydrocarbon concentration and the relative enumeration of the bacterial oil degraders was detected for some litter locations along the mediterranean Sea shore west and east Delta, Suez canal. and suez gulf. 24 petroleum utilizing bacterial isolates were isolated from El-Zayteia port (suez) and identified by morphological, physiological and environmental examination . the biodegradation capacity of the isolates towards the chosen model oil and its separate components was studied in comparison with the standard isolate pseudomonas aeruginosa. Further, the role of the bacterial plasmids taking part in the biodegradation process was investigated as well

Subsurface petroleum reservoirs are an important component of the deep biosphere where indigenous microorganisms live under extreme conditions and in isolation from the Earth's surface for millions of years. However, unlike the bulk of the deep biosphere, the petroleum reservoir deep biosphere is subject to extreme anthropogenic perturbation, with the introduction of new electron acceptors, donors and exogenous microbes during oil exploration and production. Despite the fundamental and practical significance of this perturbation, there has never been a systematic evaluation of the ecological changes that occur over the production lifetime of an active offshore petroleum production system. Analysis of the entire Halfdan oil field in the North Sea (32 producing wells in production for 1-15 years) using quantitative PCR, multigenic sequencing, comparative metagenomic and genomic bins reconstruction revealed systematic shifts in microbial community composition and metabolic potential, as well as changing ecological strategies in response to anthropogenic perturbation of the oil field ecosystem, related to length of time in production. The microbial communities were initially dominated by slow growing anaerobes such as members of the Thermotogales and Clostridiales adapted to living on hydrocarbons and complex refractory organic matter. However, as seawater and nitrate injection (used for secondary oil production) delivered oxidants, the microbial community composition progressively changed to fast growing opportunists such as members of the Deferribacteres, Delta-, Epsilon- and Gammaproteobacteria, with energetically more favorable metabolism (for example, nitrate reduction, H 2 S, sulfide and sulfur oxidation). This perturbation has profound consequences for understanding the microbial ecology of the system and is of considerable practical importance as it promotes detrimental processes such as reservoir souring and metal corrosion. These findings provide a new

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

Naval Petroleum and Oil Shale Reserves. Annual report of operations, Fiscal year 1993

International Nuclear Information System (INIS)

1993-01-01

During fiscal year 1993, the reserves generated $440 million in revenues, a $33 million decrease from the fiscal year 1992 revenues, primarily due to significant decreases in oil and natural gas prices. Total costs were $207 million, resulting in net cash flow of $233 million, compared with $273 million in fiscal year 1992. From 1976 through fiscal year 1993, the Naval Petroleum and Oil Shale Reserves generated $15.7 billion in revenues for the US Treasury, with expenses of $2.9 billion. The net revenues of $12.8 billion represent a return on costs of 441 percent. See figures 2, 3, and 4. In fiscal year 1993, production at the Naval Petroleum and Oil Shale Reserves at maximum efficient rates yielded 25 million barrels of crude oil, 123 billion cubic feet of natural gas, and 158 million gallons of natural gas liquids. The Naval Petroleum and Oil Shale Reserves has embarked on an effort to identify additional hydrocarbon resources on the reserves for future production. In 1993, in cooperation with the US Geological Survey, the Department initiated a project to assess the oil and gas potential of the program's oil shale reserves, which remain largely unexplored. These reserves, which total a land area of more than 145,000 acres and are located in Colorado and Utah, are favorably situated in oil and gas producing regions and are likely to contain significant hydrocarbon deposits. Alternatively the producing assets may be sold or leased if that will produce the most value. This task will continue through the first quarter of fiscal year 1994

Chlorine determination in crude oil is made in order to guarantee that the oil does not contain levels of this element that might cause damages in the oil processing equipment. In petroleum products, the determination of chlorine is made, for instance, to evaluate if there are proper concentrations of organochloride compounds, which are used as additives. Such determinations are currently performed following official guidelines from the ASTM International and from the United States Environmental Protection Agency as well as protocols indicated by the Universal Oil Products. X-ray fluorescence spectroscopy plays an important role in many of these official methods. In contrast, other spectrometric methods based on optical and mass detection are plagued by limitations related to both the fundamental characteristics of non-metals and to the complex sample matrices, which reflects in the small number of articles devoted to these applications. In this review, the current status of the spectrometric methods, especially the role played by X-ray fluorescence spectrometry, is evaluated in terms of the determination of chlorine in crude oil and petroleum derivatives. Comparison of the performance of the methods, limitations and potential new approaches to ensure proper spectrometric determinations of chlorine is indicated. - Highlights: • Critical evaluation of spectrometric methods for chlorine in petroleum products. • Reviews on element determination in petroleum have not address the case of chlorine. • Peculiarities of the spectrometric determination of Cl in petroleum are discussed. • The spectrometric approaches are detailed and compared to the official methods. • New trends in chlorine determination in petroleum products are indicated

Petroleum hydrocarbons are important energy resources. However, petroleum is also a major pollutant of the environment. Contamination by oil and oil products has caused serious harm, and increasing attention has been paid to the development and implementation of innovative technologies for the removal of these contaminants. Biosurfactants have been extensively used in the remediation of water and soil, as well as in the main stages of the oil production chain, such as extraction, transportation, and storage. This diversity of applications is mainly due to advantages such as biodegradability, low toxicity and better functionality under extreme conditions in comparison to synthetic counterparts. Moreover, biosurfactants can be obtained with the use of agro-industrial waste as substrate, which helps reduce overall production costs. The present review describes the potential applications of biosurfactants in the oil industry and the remediation of environmental pollution caused by oil spills.

CdO nanosheet film can be synthesized by electrochemical deposition in an ultra-thin liquid layer by using Cd(NO(3))(2) and HNO(3) as source materials for Cd and oxygen respectively. HNO(3) is also used to adjust the pH of the electrolyte. Studies on the detailed structure indicate that the synthesized CdO nanosheet film has a face-centered cubic structure with (200)-preferred orientation. The response of the CdO nanosheet film to liquefied petroleum gas (LPG) at low temperature has been significantly improved by the novel structure of film. It has exhibited excellent sensitivity and selectivity to LPG at low temperature. A new growth mechanism of electrochemical deposition has been proposed to elaborate the formation of nanosheet in an ultra-thin liquid layer. The self-oscillation of potential in the growth interface and intermediate hydroxide are responsible for the formation of nanosheets.

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

Energy Technology Data Exchange (ETDEWEB)

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

1977-02-01

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

Full Text Available Recently, the depletion of petroleum resources and the impact of exhaust emission caused by combustion towards environmental has been forced to all researchers to come out with an alternative ways to prevent this situation become worse. Liquefied petroleum gas (LPG is the most compatible and have a potential to become a source of energy for internal combustion engine. Unfortunately, the investigation of LPG in internal combustion engine among researcher still have a gap in research. Thus, in this study a 1-Dimensional simulation CAMPRO 1.6L engine model using GT-Power is developed to predict the performances of engines that using LPG as a fuel for internal combustion engine. The constructed model simulation will throughout the validation process with the experimental data to make sure the precision of this model. The validation process shows that the results have a good agreement between the simulation model and the experimental data. As a result, the performance of LPG simulation model shows that a Brake Torque (BT, Brake Power (BP and Brake Mean Effective Pressure (BMEP were significantly improved in average of 7% in comparison with gasoline model. In addition, Brake Specific Fuel Consumption (BSFC also shows an improvement by 5%, which is become more economic. Therefore, the developed GT-Power model offer a successful fuel conversion to LPG systems via retrofit technology to provide comprehensive support for implementation of energy efficient and environmental friendly vehicles.

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

Bobra, M.

1992-05-01

A study was conducted to examine the chemical and physical changes that occur in oils as a result of photooxidation. A literature review of recent studies in petroleum photochemistry revealed reported effects of photo-induced reactions in petroleum, including changes in color, polymerization, solidification, increases in solubility and toxicity, and changes in interfacial properties. A list of products reported as a result of photolysis of petroleum is presented, including such compounds as aldehydes, ketones, esters, and lactones. The photoreactivity of various petroleum components is discussed and mechanisms of photooxidation of petroleum are suggested. In the experimental portion of the study, a variety of crude oils and petroleum products were used to determine how different oils are affected by photolysis, and to examine the importance of photolysis as a weathering process. Photooxidation products from several oils were isolated and identified, including aliphatic and aromatic acids, alcohols, and phenols. Some physical manifestations attributed to photolysis included yellowing, formation of precipitates or crusts, increases in density and viscosity with time, increases of asphaltene content in some oils, changes in pH of the surrounding water, and emulsification. 51 refs., 38 figs., 18 tabs

2017-08-15

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

Elements emitted from the exhausts of new Ford Falcon Forte cars powered by unleaded petrol (ULP) and liquefied petroleum gas (LPG) were measured on a chassis dynamometer. The measurements were carried out in February, June and August 2001, and at two steady state driving conditions (60 and 80 km h -1). Thirty seven elements were quantified in the exhaust samples by inductively coupled plasma mass spectrometry (ICPMS). The total emission factors of the elements from the exhausts of ULP cars were higher than those of LPG cars at both engine speeds even though high variability in the exhaust emissions from different cars was noted. The effect of the operating conditions such as mileage of the cars, engine speed, fuel and lubricating oil compositions on the emissions was studied. To investigate the effects of these conditions, multivariate data analysis methods were employed including exploratory principal component analysis (PCA), and the multi-criteria decision making methods (MCDM), preference ranking organization method for enrichment evaluation (PROMETHEE) and geometrical analysis for interactive aid (GAIA), for ranking the cars on the basis of the emission factors of the elements. PCA biplot of the complete data matrix showed a clear discrimination of the February, June and August emission test results. In addition, (i) platinum group elements (PGE) emissions were separated from each other in the three different clusters viz. Pt with February, Pd with June and Rh with August; (ii) the motor oil related elements, Zn and P, were particularly associated with the June and August tests (these vectors were also grouped with V, Al and Cu); and (iii) highest emissions of most major elements were associated with the August test after the cars have recorded their highest mileage. Extensive analysis with the aid of the MCDM ranking methods demonstrated clearly that cars powered by LPG outperform those powered by ULP. In general, cars tested in June perform better than

In the present article, the gas sensing behaviour of nanocrystalline CuGa(2)O(4) towards H(2), liquefied petroleum gas (LPG) and NH(3) has been reported for the first time. Nanocrystalline powders of CuGa(2)O(4) having average particle sizes in the range of 30-60nm have been prepared through thermal decomposition of an aqueous precursor solution comprising copper nitrate, gallium nitrate and triethanol amine (TEA), followed by calcination at 750 degrees C for 2h. The synthesized nanocrystalline CuGa(2)O(4) powders have been characterised through X-ray diffraction (XRD), transmission electron microscopy (TEM), field-emission scanning electron microscopy (FESEM) study, energy dispersive X-ray (EDX) analysis and BET (Brunauer-Emmett-Teller) surface area measurement. The synthesized CuGa(2)O(4) having spinel structure with specific surface area of 40m(2)/g exhibits maximum sensitivity towards H(2), LPG, and NH(3) at 350 degrees C.

Selective solvent extraction of oils

Energy Technology Data Exchange (ETDEWEB)

1938-04-09

In the selective solvent extraction of naphthenic base oils, the solvent used consists of the extract obtained by treating a paraffinic base oil with a selective solvent. The extract, or partially spent solvent is less selective than the solvent itself. Selective solvents specified for the extraction of the paraffinic base oil are phenol, sulphur dioxide, cresylic acid, nitrobenzene, B:B/sup 1/-dichlorethyl ether, furfural, nitroaniline and benzaldehyde. Oils treated are Coastal lubricating oils, or naphthenic oils from the cracking, or destructive hydrogenation of coal, tar, lignite, peat, shale, bitumen, or petroleum. The extraction may be effected by a batch or counter-current method, and in the presence of (1) liquefied propane, or butane, or naphtha, or (2) agents which modify the solvent power such as, water, ammonia, acetonitrile, glycerine, glycol, caustic soda or potash. Treatment (2) may form a post-treatment effected on the extract phase. In counter-current treatment in a tower some pure selective solvent may be introduced near the raffinate outlet to wash out any extract therefrom.

Operators, paced by a feisty independent based in Port Moresby, have drilled a string of discoveries near the infrastructure of the Kutubu development project that supports Papua New Guinea crude exports. All signs point to the increasing likelihood of good sized -- maybe world class -- oil discoveries that promise to sustain exploration and development interest beyond 2000. Also in the offing are world class gas strikes that eventually could support a liquefied natural gas export project. And integration is the newest concept in Papua New Guinea petroleum. Efforts are under way to build the country's first refineries. Most operators in Papua New Guinea believe thy have merely scratched the surface of the country's oil and gas potential. Thy agree there still will be frustrations and setbacks -- political as well as technical -- but the prevailing opinion is that these problems are no greater than they are in a number of other countries with similar exploration/development potential. The paper discusses the development of Papua New Guinea's oil and gas industry, and exploratory drilling in areas other than Kutubu

Accelerating oil import dependence in energy consuming nations highlights the importance of having energy supplies at sufficient levels and at stable and reasonable prices. Consequently, it is crucial that oil exporters realize their full production potential. Current debates on energy security are often focused on short-term risks e.g. sudden disruptions due to wars, domestic instability, etc. However, when it comes to assessing oil supplier reliability it is equally important to assess their longer term ability and willingness to deliver oil to the global market. This study analyzes the effects of petroleum investment policies on crude oil production trends in 14 major oil producing countries (2000-2010) by focusing on the political-institutional frameworks that shape the investment conditions for the upstream oil sector. Our findings indicate that countries with less favorable oil sector frameworks systematically performed worse than countries with investor friendly and privatized sectors. The findings indicate that assessments based on remaining reserves and planned production capacities alone could inflate expectations about future oil supplies in a world where remaining crude reserves are located in countries with unfavorable investment frameworks. - Highlights: → We explore if policies favoring state-ownership in upstream oil undermine output expectations. → We compare petroleum policies of 14 major oil producers vis-a-vis production trends 2000-2010. → We find major differences between countries favorable to state-owned or private investors. → Substantial private investment seems needed for oil production to meet long-term demand growth.

Full Text Available Petroleum oil is a complex mixture of substances, the majority of which are hydrocarbons; the latter represent an extremely important and heterogeneous group of compounds that find their way into water resources by anthropogenic or natural ways. The majority of toxic hydrocarbon components of petroleum are biodegradable, where bioremediation using microbial species has become an integral process for the restoration of oil-polluted areas. In this study, three bioremediation processes, namely natural attenuation, nutrient supplementation by adding glucose and biostimulation by adding Tween® 80, were carried out in various petroleum hydrocarbon concentrations in polluted water media using a consortium of three protozoan isolates (Aspidisca sp., Trachelophyllum sp. and Peranema sp.. A first-order kinetics model was fitted to the biodegradation data to evaluate the biodegradation rate and to determine the corresponding half-life time. First-order kinetics satisfactorily described the biodegradation of the petroleum-based contaminants under abiotic conditions. The results showed an increase in the percentage removal of petroleum oil at the lower petroleum concentrations and a gradual percentage decrease in removing petroleum oil residues occurred when there was an increase in the initial concentrations of the petroleum oil: 39%, 27%, 22%, 12%, 10% for various petroleum oil concentrations of 50, 100, 150, 200, 250 mg/L, respectively. A similar trend was also observed in the glucose-supplemented culture media where the reduction was 45% and 78% for petroleum concentrations of 250 mg/L and 50 mg/L, respectively. Biodegradation of between 33 and 90% was achieved at a Tween® 80 concentration of between 50 mg/L and 250 mg/L. The degradation rate constants for the natural attenuation process ranged between ≥0 to ≤0.50, ≥0 to ≤0.35, ≥0 to ≤0.25, ≥0 to ≤ 0.14 and ≥ 0 to ≤0.11 for petroleum oil concentrations varying from 50, 100, 150

2017-01-01

The geochemical characteristics of fluid petroleum coke from the Athabasca Oil Sands Region (AOSR) of northern Alberta, Canada were investigated. Continuous core samples were collected to 8 m below surface at several locations (n = 12) from three coke deposits at an active oil sands mine. Bulk elemental analyses revealed the coke composition was dominated by C (84.2 ± 2.3 wt%) and S (6.99 ± 0.26 wt%). Silicon (9210 ± 3000 mg kg"−"1), Al (5980 ± 1200 mg kg"−"1), Fe (4760 ± 1200 mg kg"−"1), and Ti (1380 ± 430 mg kg"−"1) were present in lesser amounts. Vanadium (1280 ± 120 mg kg"−"1) and Ni (230 ± 80 mg kg"−"1) exhibited the highest concentrations among potentially-hazardous minor and trace elements. Sequential extractions revealed potential for release of these metals under field-relevant conditions. Synchrotron powder X-ray diffraction revealed the presence of Si and Ti oxides, organically-complexed V and hydrated Ni sulfate, and provided information about the asphaltenic carbon matrix. X-ray absorption near edge structure (XANES) spectroscopy at the V and Ni K-edges revealed that these metals were largely hosted in porphyrins and similar organic complexes throughout coke grains. Minor differences among measured V and Ni K-edge spectra were largely attributed to slight variations in local coordination of V(IV) and Ni(II) within these organic compounds. However, linear combination fits were improved by including reference spectra for inorganic phases with octahedrally-coordinated V(III) and Ni(II). Sulfur and Fe K-edge XANES confirmed that thiophenic coordination and pyritic-ilmenitic coordination are predominant, respectively. These results provide new information on the geochemical and mineralogical composition of oil sands fluid petroleum coke and improve understanding of potential controls on associated water chemistry. - Highlights: • Oil sands fluid petroleum coke contains wide range of major, minor and

Due to the toxicity of petroleum compounds, the increasing accidents of marine oil spills/leakages have had a significant impact on our environment. Recently, different remedial techniques for the treatment of marine petroleum pollution have been proposed, such as bioremediation, controlled burning, skimming, and solidifying. (Hedlund and Staley in Int J Syst Evol Microbiol 51:61-66, 2001). This review introduces an important remedial method for marine oil pollution treatment-bioremediation technique-which is considered as a reliable, efficient, cost-effective, and eco-friendly method. First, the necessity of bioremediation for marine oil pollution was discussed. Second, this paper discussed the species of oil-degrading microorganisms, degradation pathways and mechanisms, the degradation rate and reaction model, and the factors affecting the degradation. Last, several suggestions for the further research in the field of marine oil spill bioremediation were proposed.

This research was carried out to determine the risk impact of Liquefied Petroleum Gas (LPG) storage facilities, especially in the event of LPG tank explosion. In order to prevent the LPG tank explosion from occurring, it is important to decide the most suitable operating condition for the LPG tank itself, as the explosion of LPG tank could affect and cause extensive damage to the surrounding. The explosion of LPG tank usually occurs due to the rise of pressure in the tank. Thus, in this research, a method called Planas-Cuchi was applied to determine the Peak Side-On Overpressure (Po) of the LPG tank during the occurrence of explosion. Thermodynamic properties of saturated propane, (C3H8) have been chosen as a reference and basis of calculation to determine the parameters such as Explosion Energy (E), Equivalent Mass of TNT (WTNT), and Scaled Overpressure (PS ). A cylindrical LPG tank in Feyzin Refinery, France was selected as a case study in this research and at the end of this research, the most suitable operating pressure of the LPG tank was determined.

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

International Nuclear Information System (INIS)

Bello, Alejandro; Huerta, Emilio

2007-01-01

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

Highlights: → Low temperature synthesis of mesoporous ZnO thin films by CBD method with urea containing bath. → Wurtzite crystal structure of mesoporous ZnO has been confirmed from the XRD study. → SEM images reveal the formation of hydrophobic mesoporous ZnO thin films. → Maximum LPG response of 52% has been achieved with high stability. - Abstract: In the present work, we report base free chemical bath deposition (CBD) of mesoporous zinc oxide (ZnO) thin films from urea containing bath for liquefied petroleum gas (LPG) sensor application. Mesoporous morphology with average pore size ∼2 μm and wurtzite crystal structure are confirmed from scanning electron microscopy (SEM) and X-ray diffraction (XRD) analysis. The surface of ZnO is hydrophobic with water contact angle 128 ± 1 o . Optical study reveals the presence of direct bad gap with energy 3.24 eV. The gas sensing study reveals the mesoporous ZnO is highly selective towards LPG as compared with CO 2 and maximum LPG response of 52% is achieved upon the exposure of 3900 ppm LPG at 573 K as well as good reproducibility and short response/recovery times.

Bioaccumulation of petroleum hydrocarbons in arctic amphipods in the oil development area of the Alaskan Beaufort Sea.

2012-04-01

An objective of a multiyear monitoring program, sponsored by the US Department of the Interior, Bureau of Ocean Energy Management was to examine temporal and spatial changes in chemical and biological characteristics of the Arctic marine environment resulting from offshore oil exploration and development activities in the development area of the Alaskan Beaufort Sea. To determine if petroleum hydrocarbons from offshore oil operations are entering the Beaufort Sea food web, we measured concentrations of hydrocarbons in tissues of amphipods, Anonyx nugax, sediments, Northstar crude oil, and coastal peat, collected between 1999 and 2006 throughout the development area. Mean concentrations of polycyclic aromatic hydrocarbons (PAH), saturated hydrocarbons (SHC), and sterane and triterpane petroleum biomarkers (StTr) were not significantly different in amphipods near the Northstar oil production facility, before and after it came on line in 2001, and in amphipods from elsewhere in the study area. Forensic analysis of the profiles (relative composition and concentrations) of the 3 hydrocarbon classes revealed that hydrocarbon compositions were different in amphipods, surface sediments where the amphipods were collected, Northstar crude oil, and peat from the deltas of 4 North Slope rivers. Amphipods and sediments contained a mixture of petrogenic, pyrogenic, and biogenic PAH. The SHC in amphipods were dominated by pristane derived from zooplankton, indicating that the SHC were primarily from the amphipod diet of zooplankton detritus. The petroleum biomarker StTr profiles did not resemble those in Northstar crude oil. The forensic analysis revealed that hydrocarbons in amphipod tissues were not from oil production at Northstar. Hydrocarbons in amphipod tissues were primarily from their diet and from river runoff and coastal erosion of natural diagenic and fossil terrestrial materials, including seep oils, kerogens, and peat.

Evidence that the terms of petroleum contracts influence the rate of development of oil fields

International Nuclear Information System (INIS)

Mahmud, M.B.; Russell, A.

2002-01-01

This paper presents evidence that the main determinant of the rate of development of Libya's crude oil upstream activities, from 1961 to 1999, was the terms of the petroleum contractual agreements, which existed between the state and the international oil industry during that period, and that US sanctions against the Socialist People's Libyan Arab Jamahiriya failed to affect this rate of development. In keeping with other Members of the Organisation of the Petroleum Exporting Countries (OPEC), Libya has, over three decades, been a key player in helping to regulate global production levels of oil and gas. However, the economic and political strengths and weaknesses of individual Members of OPEC vary widely and it is inevitable that the stresses arising from adherence to OPEC policies will vary proportionately to these strengths and weaknesses. It is instructive, therefore, to analyse how successfully Libya has exploited its own petroleum resources. The results are thought-provoking and send signals to the superpowers of the futility of economic sanctions against countries whose political policies they find distasteful. Further, the analysis highlights the need for OPEC Members to be fully informed of the significance of the terms of the petroleum agreements they employ in their countries. (author)

2003-01-01

To effectively determine the fate of spilled oil in the environment and to successfully identify the source(s) of spilled oil and petroleum products is extremely important in many oil-related environmental studies and liability cases. This article briefly reviews the most recent developments and advances of the gas chromatography-based technologies that are most frequently used in oil-spill characterization and identification studies. The effects of oil weathering on the chemical composition features and changes of spilled oils in the environment are also addressed. The fingerprinting and data interpretation techniques discussed include recognition of distribution patterns of petroleum hydrocarbons, oil type screening and differentiation, analysis of 'source-specific marker' compounds, determination of diagnostic ratios of specific oil constituents, and application of various statistical and numerical analysis tools.

Oil market structures-strategies and performances of the actors of the international petroleum system

International Nuclear Information System (INIS)

Djermaine, Rebai

1999-01-01

The rises of petroleum prices as revealed by the oil crises of the 1970's are the consequences of a beside market perverse game between artificial factors. The public management and the intervention of public authorities have contributed to the unbalancing of oil markets and to the confusion of the actor's strategies in the international petroleum system. The chronical decay of the petroleum prices indicate the slow and silent come back of the economical forces (laws). The management of an exhaustible asset like petroleum, raises lot of intriguing problems. This work aims at exploring the problems linked with this type of management where the decisions of the profession, of private and public companies and of the governments are closely interfering. The study is largely inspired of the meso-economical approach which consists in examining the markets structure and their determining factors, and the strategies and results of the actors of the world petroleum system. The examination of the structures/strategies/results sequence does not neglect the relations and feedbacks between each of these elements. The economical theory of oligopoly and cartel markets is also used to examine the way how prices are determined in petroleum markets. A critical presentation of the energy models allows to show how it is possible to understand, foresee and control the evolution of these prices and the possible supply/demand equilibrium. The study takes also into consideration the debates and controversies about the 'green tax' and its impact of petroleum supply and demand. (J.S.)

In the experimental study conducted on a spark ignition (SI) car running on a chassis dynamometer, fuelled on liquefied petroleum gas (LPG) and gasoline, carbon monoxide (CO) and total hydrocarbons (HC) decreased by 37.3% and 46.8%, respectively, while oxides of nitrogen (NOx) increased by 59.7% due to higher compression ratio with LPG, compared with gasoline. In case of LPG fuel, formaldehyde, acetaldehyde, propionaldehyde, 2-butanone, butyraldehyde, benzaldehyde and valeraldehyde decreased, leading to an over all decrease of about 35% and 26% in carbonyls and their ozone forming potential (OFP), respectively, compared with gasoline. Furthermore, benzene, toluene, ethyl benzene, xylene and styrene decreased, resulting in an overall decrease of 38.8% in volatile organic compounds (VOCs) and 39.2% in BTEX (benzene, toluene, ethyl benzene and xylene) species due to more complete combustion with LPG, compared with gasoline. Further, the OFP of VOCs with LPG was 6% lower than that with gasoline fuel. (author)

Hydrodynamic thickness of petroleum oil adsorbed layers in the pores of reservoir rocks.

Science.gov (United States)

Alkafeef, Saad F; Algharaib, Meshal K; Alajmi, Abdullah F

2006-06-01

The hydrodynamic thickness delta of adsorbed petroleum (crude) oil layers into the pores of sandstone rocks, through which the liquid flows, has been studied by Poiseuille's flow law and the evolution of (electrical) streaming current. The adsorption of petroleum oil is accompanied by a numerical reduction in the (negative) surface potential of the pore walls, eventually stabilizing at a small positive potential, attributed to the oil macromolecules themselves. After increasing to around 30% of the pore radius, the adsorbed layer thickness delta stopped growing either with time or with concentrations of asphaltene in the flowing liquid. The adsorption thickness is confirmed with the blockage value of the rock pores' area determined by the combination of streaming current and streaming potential measurements. This behavior is attributed to the effect on the disjoining pressure across the adsorbed layer, as described by Derjaguin and Churaev, of which the polymolecular adsorption films lose their stability long before their thickness has approached the radius of the rock pore.

Mass transfer of H2O between petroleum and water: implications for oil field water sample quality

International Nuclear Information System (INIS)

McCartney, R.A.; Ostvold, T.

2005-01-01

Water mass transfer can occur between water and petroleum during changes in pressure and temperature. This process can result in the dilution or concentration of dissolved ions in the water phase of oil field petroleum-water samples. In this study, PVT simulations were undertaken for 4 petroleum-water systems covering a range of reservoir conditions (80-185 o C; 300-1000 bar) and a range of water-petroleum mixtures (volume ratios of 1:1000-300:1000) to quantify the extent of H 2 O mass transfer as a result of pressure and temperature changes. Conditions were selected to be relevant to different types of oil field water sample (i.e. surface, downhole and core samples). The main variables determining the extent of dilution and concentration were found to be: (a) reservoir pressure and temperature, (b) pressure and temperature of separation of water and petroleum, (c) petroleum composition, and (d) petroleum:water ratio (PWR). The results showed that significant dilution and concentration of water samples could occur, particularly at high PWR. It was not possible to establish simple guidelines for identifying good and poor quality samples due to the interplay of the above variables. Sample quality is best investigated using PVT software of the type used in this study. (author)

Determination of hydrogen content of petroleum products from Tema Oil Refinery using neutron backscatter technique

International Nuclear Information System (INIS)

Salifu, A. S.

2015-01-01

The hydrogen content of hydrocarbon materials is very important in several areas of industrial process such as mining, vegetable oil extraction and crude oil exploration and refining. A fast and more universal technique based on thermal neutron reflection was employed to determine the total hydrogen contents of petroleum samples from Tema Oil Refinery (TOR) and Crude oil samples from Jubilee field and Nigeria. The experimental set-up consisted of a source-holder housing a 1Ci Am-Be neutron source and a He-3 neutron detector. Two geometrical arrangements were considered and their sensitivities were compared. The set-up was used to measure the excess neutron count in both geometrical considerations and their reflection parameters were calculated as a function of hydrogen content of the samples. Calibration lines were deduced using liquid hydrocarbons containing well-known hydrogen and carbon contents as standards. Two linear equations were generated from the calibration lines and were used to further determine the hydrogen content of thirteen (13) petroleum samples obtained from Quality Control Department of TOR. The total hydrogen contents were found to be in the range of 7.211(hw %) - 15.069 (hw %) for vertical geometry and 7.206 (hw %) - 14.948 (hw %) for horizontal geometry respectively. The results obtained agreed constructively with other results obtained using different methodologies by other studies. The percentage error of the hydrogen contents denoted by (% E) for the various petroleum samples were also obtained and noticed to be within an acceptable range. The neutron backscatter technique was observed as an alternative and more generalized method for quality assurance and standardization in the petroleum industries

The petroleum industry in China

International Nuclear Information System (INIS)

1993-06-01

A review is presented of China's petroleum industry. In recent years China has ranked as the world's fifth or sixth largest oil producer, providing ca 20% of China's energy needs and generating US $45 billion in exports during 1988-89. However, domestic oil consumption is rapidly outpacing growth in production, and China may become a net oil importer as early as March 1994 if trends continue. In order to slow declining production rates, China must: introduce modern management techniques, equipment and technology; accelerate exploration to find new reserves; employ the latest equipment and technology, consulting services and foreign training to develop new reserves as quickly as possible; and improve the efficiency with which petroleum is used and traded. Key players including the China National Petroleum Corporation, China National Oil Development Corporation, China National United Oil Company, and China National Offshore Oil Corporation are described. Current Chinese petroleum industry priorities are discussed, together with Canadian capabilities relevant to these activities, and recent bilateral agreements in the sector

1996-05-01

This report summarizes the results of a survey of residential No. 2 distillate fuel (home heating oil) and liquefied petroleum gas (propane) prices over the 1995--1996 heating season in Michigan. The Michigan's Public Service Commission (MPSC) conducted the survey under a cooperative agreement with the US Department of Energy's (DOE) Energy Information Administration (EIA). This survey was funded in part by a grant from the DOE. From October 1995 through March 1996, the MPSC surveyed participating distributors by telephone for current residential retail home heating oil and propane prices. The MPSC transmitted the data via a computer modem to the EIA using the Petroleum Electronic Data Reporting Option (PEDRO). Survey results were published in aggregate on the MPSC World Wide Web site at http://ermisweb.state.mi.us/shopp. The page was updated with both residential and wholesale prices immediately following the transmission of the data to the EIA. The EIA constructed the survey using a sample of Michigan home heating oil and propane retailers. The sample accounts for different sales volumes, geographic location, and sources of primary supply

The impact of liquefied petroleum gas usage on air quality in Mexico City

International Nuclear Information System (INIS)

Gasca, J.; Ortiz, E.; Castillo, H.; Jaimes, J.L.; Gonzalez, U.

2004-01-01

Liquefied petroleum gas (LPG) is the main fuel used in the residential sector of the Metropolitan Zone in the Valley of Mexico (MZVM). LPG represents 16% of the total fuel consumption in the MZVM and its demand increased 14% from 1986 to 1999. Propane and butanes, the main compounds of LPG, constituted 29% of all non-methane hydrocarbons found in the air of Mexico City. Some researchers have reported that LPG losses are a significant cause of high ozone concentration in MZVM. Three analyses are carried out in this work to estimate LPG's share of responsibility for MZVM pollution problems. First, the correlation between LPG consumption and three ozone pollution indicators was calculated for the period of 1986-1999. The non-significant correlation of these indicators with LPG consumption on a monthly basis suggests that LPG associated emissions are not the foremost cause of ozone formation. Second, a simulation model is applied to three LPG related emission control strategies to estimate the reduction in the maximum ozone concentration. The most noticeable effect was obtained when both hydrocarbon (HC) and oxides of nitrogen (NO x ) emissions associated with LPG use were totally reduced. The other two strategies, that only reduce HC emissions, had a minimum effect on the ozone concentration. Third, organic compounds consumption in air samples captured and irradiated in outdoor smog chambers is used to determine the chemical loss rate of LPG associated species and aromatics in the MZVM. The smog chamber results showed that 70% of propane and n-butane remain at the end of a 1-day irradiation, therefore they remain in the MZVM atmosphere for several days being the reason for the high concentration of these compounds. LPG associated compounds only account for 18% of ozone formed but aromatics contribute 35% to ozone in smog chamber. (Author)

Exposure of a liquefied gas container to an external fire

International Nuclear Information System (INIS)

Raj, Phani K.

2005-01-01

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

Full Text Available In this work, an experimental work was carried out to compare the performance of biodiesels made from non edible mahua oil and edible gingili oil in dual fuel engine. A single cylinder diesel engine was modified to work in dual fuel mode and liquefied petroleum gas was used as primary fuel. Biodiesel was prepared by transesterification process and mahua oil methyl ester (MOME and gingili oil methyl ester (GOME were used as pilot fuels. The viscosity of MOME is slightly higher than GOME. The dual fuel engine runs smoothly with MOME and GOME. The test results show that the performance of the MOME is close to GOME, at the pilot fuel quantity of 0.45 kg/h and at the advanced injection timing of 30 deg bTDC. Also it is observed that the smoke, carbon monoxide and unburnt hydro carbon emissions of GOME lower than the MOME. But the GOME results in slightly higher NOx emissions. From the experimental results it is concluded that the biodiesel made from mahua oil can be used as a substitute for diesel in dual fuel engine.

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

2018-02-01

The incidence of liquefied petroleum gas (LPG)-related burns has increased over recent years, and it has become a serious public health issue in developing countries such as India and Turkey. This paper aims to investigate the epidemiological characteristics of LPG-related burns to provide assistance and suggestions for planning prevention strategies. A 5-year retrospective study was conducted in patients with LPG-related burns admitted to the Department of Burns & Wound Care Center, Second Affiliated Hospital of Zhejiang University, College of Medicine, between 1st January 2011 and 31st December 2015. Information obtained for each patient included age, gender, education status, occupation, medical insurance, average hospital cost, length of hospital stay, monthly distribution of incidence, place of burns, mechanism of burns, extent of burns, site of burns, accompanying injuries, and treatment outcomes. For the first 4 years (2011-2014), the yearly incidence of LPG-related burns was at approximately 10% of all burns; however, in the fifth year (2015) alone, there was a surge to 26.94%. A total of 1337 burn patients were admitted during this period. Of these, 195 patients were admitted because of 169 LPG-related accidents; there were 11 accidents involving more than one victim. LPG-related burns occurred most frequently in patients aged 21-60 years (73.85%). The majority of injuries occurred from May to August (56.41%), and the most common place was home (83.08%, 162 patients). Gas leak (81.03%) was the main cause of LPG-related burns, followed by inappropriate operation (7.69%) and cooking negligence (2.05%). The mean burn area was 31.32±25.40% of TBSA. The most common sites of burns were the upper extremities (37.47%), followed by the head/face and neck (24.80%) and lower extremities (19.95%). The most common accompanying injuries included inhalation injury (23.59%), shock (8.71%), and external injury (7.18%). The average hospital stay was 22.90±19.47days (range

This project is part of a collaboration effort between Iowa State University (ISU), University of Oklahoma (OK) and Pacific Northwest National Laboratory (PNNL). The purpose of this project is to stabilize bio-oil fractions and improve their suitability for insertion into petroleum refineries. Bio-oil from fast pyrolysis of biomass is a complex mixture of unstable organic compounds. These organic compounds react under standard room conditions resulting in increases in bio-oil viscosity and water content – both detrimental for bio-oil storage and transportation. This study employed fractionation and upgrading systems to improve the stability of bio-oil. The fractionation system consists of a series of condensers, and electrostatic precipitators designed to separate bio-oil into five fractions: soluble carbohydrates (SF1&2), clean phenolic oligomers (CPO) and middle fraction (SF3&4), light oxygenates (SF5). A two-stage upgrading process was designed to process bio-oil stage fractions into stable products that can be inserted into a refinery. In the upgrading system, heavy and middle bio-oil fractions were upgraded into stable oil via cracking and subsequent hydrodeoxygenation. The light oxygenate fraction was steam reformed to provide a portion of requisite hydrogen for hydroprocessing. Hydrotreating and hydrocracking employed hydrogen from natural gas, fuel gas and light oxygenates reforming. The finished products from this study consist of gasoline- and diesel-blend stock fuels.

METHODOLOGY FOR ESTIMATION OF STATIONARY AND DYNAMIC PARAMETERS FOR LIQUEFIED PETROLEUM GAS (LPG RE-LIQUEFACTION IN SPHERICAL STORAGE SYSTEMS

Full Text Available Temperature difference between the environment and the liquid contained in the liquefied petroleum gas storage spheres produces: net inward heat flow, increase in stored fuel temperature, LPG partial vaporization and consequently an increase in storage pressure. In order to maintain adequate safety conditions, since uncontrolled pressure increases could lead to risky situations and economic losses, re-liquefaction systems, consisting on auto refrigeration units, are installed; this system extracts the evaporated gas, compress it and then condense it again in a closed cooling cycle. Frequently these systems are designed using heuristic criteria, without considering the calculations necessary for correct equipment sizing; this results in costly modifications or in oversized equipment. In the present article, a simple but effective methodology for the calculation of thermal loads, daily temperature increase rate and pressure accumulation and restore times is presented, the methodology was compared with real data, through data acquisition and processing during the summer months of 2015 and 2016 for 12 storage spheres in a gas company located in a coastal state of Mexico, finding that the values predicted for the rate of daily temperature increase and recovery times are statistically consistent with the experimental data.

Several methods are available for the characterization of petroleum hydrocarbons. The TPHCWG (Total Petroleum Hydrocarbon Criteria Working Group) developed a method based on a silica column separation of aromatics and aliphatics and a GC-FID subdivision into equivalent-carbon fractions (EC) ('TPH-method'). This method was mainly developed for assessing human risks of oil compounds. Within NOBIS (Dutch Research program Biological In-situ Remediation), another method was developed based upon an equilibrium-experiment of the oil-polluted soil with water (column recirculation), which was further developed by TTE ('TTE-method'). This method uses measured water solubilities of individual oil components and GC-retention times yielding a subdivision of the hydrocarbons into compound classes that are relevant for assessing the remediation potential of the specific oil pollution. In this paper we present results of a research project in which we developed a new method, the 'OK-method' that combines these two procedures and allows a complete characterisation of the oil in terms of composition, (human) risks, volatility, solubility, plume behaviour (migration velocities of the soluble components) and aerobic degradation potential.

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

Summary: Petroleum resource assessments are among the most highly visible and frequently cited scientific products of the U.S. Geological Survey. The assessments integrate diverse and extensive information on the geologic, geochemical, and petroleum production histories of provinces and regions of the United States and the World. Petroleum systems modeling incorporates these geoscience data in ways that strengthen the assessment process and results are presented visually and numerically. The purpose of this report is to outline the requirements, advantages, and limitations of one-dimensional (1-D), two-dimensional (2-D), and three-dimensional (3-D) petroleum systems modeling that can be applied to the assessment of oil and gas resources. Primary focus is on the application of the Integrated Exploration Systems (IES) PetroMod? software because of familiarity with that program as well as the emphasis by the USGS Energy Program on standardizing to one modeling application. The Western Canada Sedimentary Basin (WCSB) is used to demonstrate the use of the PetroMod? software. Petroleum systems modeling quantitatively extends the 'total petroleum systems' (TPS) concept (Magoon and Dow, 1994; Magoon and Schmoker, 2000) that is employed in USGS resource assessments. Modeling allows integration of state-of-the-art analysis techniques, and provides the means to test and refine understanding of oil and gas generation, migration, and accumulation. Results of modeling are presented visually, numerically, and statistically, which enhances interpretation of the processes that affect TPSs through time. Modeling also provides a framework for the input and processing of many kinds of data essential in resource assessment, including (1) petroleum system elements such as reservoir, seal, and source rock intervals; (2) timing of depositional, hiatus, and erosional events and their influences on petroleum systems; (3) incorporation of vertical and lateral distribution and lithologies of

Cooking with dirty-burning fuels is associated with health risk from household air pollution. We assessed the prevalence of and factors associated with the use of cooking fuels, and attitudes and barriers towards use of liquefied petroleum gas (LPG). This was a cross-sectional, population-based survey conducted in 519 households in Lagos, Nigeria. We used a structured questionnaire to obtain information regarding choice of household cooking fuel and the attitudes towards the use of LPG. Kerosene was the most frequently used cooking fuel ( n = 475, 91.5%; primary use n = 364, 70.1%) followed by charcoal ( n = 159, 30.6%; primary use n = 88, 17%) and LPG ( n = 86, 16.6%; primary use n = 63, 12.1%). Higher level of education, higher income and younger age were associated with LPG vs. kerosene use. Fuel expenditure on LPG was significantly lower than for kerosene ( N (Naira) 2169.0 ± 1507.0 vs. N 2581.6 ± 1407.5). Over 90% of non-LPG users were willing to switch to LPG but cited safety issues and high cost as potential barriers to switching. Our findings suggest that misinformation and beliefs regarding benefits, safety and cost of LPG are important barriers to LPG use. An educational intervention program could be a cost-effective approach to improve LPG adoption and should be formally addressed through a well-designed community-based intervention study.

On-board measurements of unit emissions of CO, HC, NOx and CO₂ were conducted on 17 private cars powered by different types of fuels including gasoline, dual gasoline-liquefied petroleum gas (LPG), gasoline, and diesel. The tests performed revealed the effect of LPG injection technology on unit emissions and made it possible to compare the measured emissions to the European Artemis emission model. A sequential multipoint injection LPG kit with no catalyst installed was found to be the most efficient pollutant reduction device for all of the pollutants, with the exception of the NOx. Specific test results for a sub-group of LPG vehicles revealed that LPG-fueled engines with no catalyst cannot compete with catalyzed gasoline and diesel engines. Vehicle age does not appear to be a determining parameter with regard to vehicle pollutant emissions. A fuel switch to LPG offers many advantages as far as pollutant emissions are concerned, due to LPG's intrinsic characteristics. However, these advantages are being rapidly offset by the strong development of both gasoline and diesel engine technologies and catalyst converters. The LPG's performance on a chassis dynamometer under real driving conditions was better than expected. The enforcement of pollutant emission standards in developing countries is an important step towards introducing clean technology and reducing vehicle emissions. Copyright © 2014.

This work presents the indicative planning of the expansion of the infrastructure from liquefied petroleum gases (LPG) in the five years (2002-07). With base in the forecast of the demand - using the data of the offer, consumption, stock and the evaluation of the existent infrastructure (ports, terminals, tanks etc.) - it is evaluated the storage need and movement of the product. Compared to the period 1998-2003, a decrease was verified accentuated in the very superior consumption to the projected value. One of the causes was the increase in the price of LPG; other, the reduction in the number of the homes with LPG. Being considered the sceneries of LPG in this five years and the number of families, the perspective is the reduction of 5,6% in the consumption of LPG, being reached 6.307 thousand tons in 2007. For the period for an increase of 20% is waited in the offer it interns of the product that, together with the smallest demand, it will provoke a reduction of more than a fourth of the imports: 1.763 kt in 2002, for 403 kt in 2007. In spite of the reduction in the consumption and maintenance of the stock, the estimate of LPG will only increase of 20,6 days for 21,8 days, however the Brazil will be self-sufficient. (author)

Tellez, G.; Khandan, N.

1995-12-31

The feasibility of removing petroleum hydrocarbons from oil fields produced waters using biological treatment was evaluated under laboratory and field conditions. Based on previous laboratory studies, a field-scale prototype system was designed and operated over a period of four months. Two different sources of produced waters were tested in this field study under various continuous flow rates ranging from 375 1/D to 1,800 1/D. One source of produced water was an open storage pit; the other, a closed storage tank. The TDS concentrations of these sources exceeded 50,000 mg/l; total n-alkanes exceeded 100 mg/l; total petroleum hydrocarbons exceeded 125 mg/l; and total BTEX exceeded 3 mg/l. Removals of total n-alkanes, total petroleum hydrocarbons, and BTEX remained consistently high over 99%. During these tests, the energy costs averaged $0.20/bbl at 12 bbl/D.

Petroleum Technology Advances Through Applied Research by Independent Oil Producers is a program of the National Oil Research Program, U.S. Department of Energy. Between 1995 and 1998, the program competitively selected and cost-shared twenty-two projects with small producers. The purpose was to involve small independent producers in testing technologies of interest to them that would advance (directly or indirectly) one or more of four national program objectives: (1) Extend the productive life of reservoirs; (2) Increase production and/or reserves; (3) Improve environmental performance; and (4) Broaden the exchange of technology information.

The need for more energy as our population grows results in an increase in the amount of CO2 introduced into the atmosphere. The effect of this introduction is currently debated intensely as to the severity of the effect of this. The bjective of this investigation was to determine if the production of more energy (i.e. petroleum) and the sequestration of CO2 could be coupled into one process. Carbon dioxide flooding is a well-established technique that introduces Compressed CO2 into a subsurface oil-bearing formation to aide in liquefying harder to extract petroleum and enhancing its mobility towards the production wells.

Radiation processing studies on residual fractions of Olowi petroleum crude oil

Residual fuel oil is an inexpensive boiler fuel that can replace diesel in some industrial boilers. The viscous waxy nature of residual fuel oil makes it very difficult to use in industries where fuel storage tanks have no heating elements to keep the fuel at temperatures at which it would easily flow. Irradiation is currently being studied as a cost effective means of cracking heavy petroleum crude oil into lighter and more valuable products. Research has shown that irradiation can replace the conventional methods of cracking petroleum with economical benefits. Gamma radiation from a cobalt-60 source was applied to the residue obtained after refining crude oil in this research study, with the intention of causing a similar cracking phenomenon. The main objective of the study was to evaluate the possibility of using gamma radiation to reduce the viscosity of residual fractions of crude oil used as residual fuel oil. This was done by exposing samples of residual fuel oil in glass jars to 9 different doses of gamma radiation, at room temperature and an elevated temperature of 60 degrees Celsius to determine and quantify the effect of radiation on residual fuel oil obtained from the Tema Oil Refinery. The pour points of the irradiated samples were not affected by radiation doses up to 200 kGy while the changes in viscosity for irradiation at room temperature were not significant. Irradiation at 60 degrees Celsius induced a small but significant increase in viscosity at 1 kGy and 200 kGy absorbed doses of irradiation. Irradiation fuels were stable in relation to viscosity, density and pour point over a period of 20 days after exposure. The flash point of irradiated samples, however, decreased by 5.26, 10.53 and 11.34% for 30, 50 and 80 kGy absorbed doses of radiation respectively. Cumulative and continuous doses gave similar results for pour point, density, viscosity and flash point measurements up to 50 kGy. Comparative cost analysis of methods used in maintaining low

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

The study items for the current fiscal year are as follows: (1) fundamental studies on coal liquefying reactions, (2) studies on product reforming, and (3) studies on product utilization. In Item 1, investigations were given on effects of hydrogenation treatment for a heavy circulation solvent in the coal liquefying reactions imposed on yield and nature of the product oil. Liquefying reactions were carried out under the presence of various heavy solvents having different hydrogen donating performances, or iron-based and oil soluble solvents. Liquefaction rates, yields and natures of different products were analyzed to discuss the degree of hydrogen donating performance of the solvents, the using conditions for the catalysts in the primary liquefying reaction, and the reaction conditions to enhance the product oil yield. In Item 2, hydrogenation treatment was given on the heavy oil fraction of the product oil obtained from the liquefying reaction using a heavy circulating solvent. The result was compared with the result on the medium oil fraction. Light oil fraction obtained from brown coal liquefaction was reformed to manufacture the reformed oil for engine tests. In Item 3, nature analysis and combustion tests were performed on the light oil fraction of the liquefied oil using brown coal as the material, and on the hydrogenated oil as a diesel engine fuel. The reforming effects were discussed from the amount and nature of the exhaust gas. (NEDO)

Full Text Available To get a better knowledge on how archaeal communities differ between the oil and aqueous phases and whether environmental factors promote substantial differences on microbial distributions among production wells, we analyzed archaeal communities in oil and aqueous phases from four high-temperature petroleum reservoirs (55–65°C by using 16S rRNA gene based 454 pyrosequencing. Obvious dissimilarity of the archaeal composition between aqueous and oil phases in each independent production wells was observed, especially in production wells with higher water cut, and diversity in the oil phase was much higher than that in the corresponding aqueous phase. Statistical analysis further showed that archaeal communities in oil phases from different petroleum reservoirs tended to be more similar, but those in aqueous phases were the opposite. In the high-temperature ecosystems, temperature as an environmental factor could have significantly affected archaeal distribution, and archaeal diversity raised with the increase of temperature (p < 0.05. Our results suggest that to get a comprehensive understanding of petroleum reservoirs microbial information both in aqueous and oil phases should be taken into consideration. The microscopic habitats of oil phase, technically the dispersed minuscule water droplets in the oil could be a better habitat that containing the indigenous microorganisms.

Total petroleum hydrocarbons (TPH) or petroleum hydrocarbons (PHC) are one of the most widespread soil contaminants in Canada, the United States and many other countries worldwide. Clean-up of PHC-contaminated soils costs the Canadian economy hundreds of millions of dollars annually. In Canada, most PHC-contaminated site evaluations are based on the methods developed by the Canadian Council of the Ministers of the Environment (CCME). However, the CCME method does not differentiate PHC from BOC (the naturally occurring biogenic organic compounds), which are co-extracted with petroleum hydrocarbons in soil samples. Consequently, this could lead to overestimation of PHC levels in soil samples. In some cases, biogenic interferences can even exceed regulatory levels (300 μg g(-1) for coarse soils and 1300 μg g(-1) for fine soils for Fraction 3, C(16)-C(34) range, in the CCME Soil Quality Level). Resulting false exceedances can trigger unnecessary and costly cleanup or remediation measures. Therefore, it is critically important to develop new protocols to characterize and quantitatively differentiate PHC and BOC in contaminated soils. The ultimate objective of this PERD (Program of Energy Research and Development) project is to correct the misconception that all detectable hydrocarbons should be regulated as toxic petroleum hydrocarbons. During 2009-2010, soil and plant samples were collected from over forty oil-contaminated and paired background sites in various provinces. The silica gel column cleanup procedure was applied to effectively remove all target BOC from the oil-contaminated sample extracts. Furthermore, a reliable GC-MS method in combination with the derivatization technique, developed in this laboratory, was used for identification and characterization of various biogenic sterols and other major biogenic compounds in these oil-contaminated samples. Both PHC and BOC in these samples were quantitatively determined. This paper reports the characterization

Full Text Available Two different phenolic synthetic antioxidants were used to improve the oxidation stability of fish oil biodiesel blends with vegetable oil biodiesel and petroleum diesel. Butylhydroxytoluene (BHT most effective for improvement of the oxidation stability of petro diesel, whereas  tert-butylhydroquinone (TBHQ showed good performance in fish oil biodiesel. Fish oil/Rapeseed oil biodiesel mixed showed some acceptable results in higher concentration ofantioxidants. TBHQ showed better oxidation stability than BHT in B100 composition. In fish oil biodiesel/diesel mixed fuel, BHT was more effective antioxidant than TBHQ to increase oxidationstability because BHT is more soluble than TBHQ. The stability behavior of biodiesel/diesel blends with the employment of the modified Rancimat method (EN 15751. The performance ofantioxidants was evaluated for treating fish oil biodiesel/Rapeseed oil biodiesel for B100, and blends with two type diesel fuel (deep sulfurization diesel and automotive ultra-low sulfur or zero sulfur diesels. The examined blends were in proportions of 5, 10, 15, and 20% by volume of fish oilbiodiesel.

Experimental analysis on a spark ignition petrol engine fuelled with LPG (liquefied petroleum gas)

2012-01-01

The use of LPG (liquefied petroleum gas) as alternative fuel to petrol is common practise in spark ignition engines. While the main driving force to the use of LPG still remains the low cost for the end user, its favourable pollutant emissions, in particular carbon dioxide, will in the middle term probably increase interest in LPG as an IC engine fuel. In addition, there are both theoretical and technical reasons to consider LPG as an attractive fuel also in terms of engine performance. Despite the continuously increasing stock production of dual-fuel (petrol–LPG) passenger car models, doubts still exist about both real engine performance in LPG operation and the reliability of the dual-fuel feeding system. This paper deals with the theoretical advantages of using LPG as fuel for SI engines. Brake performance tests of a passenger car engine fed with petrol and LPG are analysed and compared. The stock engine has been equipped with a “third-generation” standard kit for dual-fuel operation. The performance reductions in LPG operation are discussed in both steady state and transient condition. The results of some modifications to the set-up of both the petrol and LPG metering devices, designed for a better justification of the measured performance, are also presented. -- Highlights: ► Experimental research on the actual performances of an SI engine fed with petrol and gaseous LPG. ► Theoretical advantages and drawbacks of fuelling SI ICE’s with LPG. ► Brake performance analysis shows a noticeable gap between LPG and petrol operation. ► Local measurements confirm that the thermodynamic operation of the evaporator-pressure reducer device is crucial for the engine performance. ► The performance of the up-to-date kit for petrol–LPG dual-fuel operation is greatly affected by the settings of the mechanical components of the LPG evaporator device.

This study presents a quantitative gas chromatography-mass spectrometry analysis of bicyclic sesquiterpanes (BSs) in numerous crude oils and refined petroleum products including light and mid-range distillate fuels, residual fuels, and lubricating oils collected from various sources. Ten commonly recognized bicyclic sesquiterpanes were determined in all the studied crude oils and diesel range fuels with principal dominance of BS3 (C(15)H(28)), BS5 (C(15)H(28)) and BS10 (C(16)H(30)), while they were generally not detected or in trace in light fuel oils like gasoline and kerosene and most lubricating oils. Laboratory distillation of crude oils demonstrated that sesquiterpanes were highly enriched in the medium distillation fractions of approximately 180 to 481 degrees C and were generally absent or very low in the light distillation fraction (boiling point to approximately 180 degrees C) and the heavy residual fraction (>481 degrees C). The effect of evaporative weathering on a series of diagnostic ratios of sesquiterpanes, n-alkanes, and biomarkers was evaluated with two suites of weathered oil samples. The change of abundance of sesquiterpanes was used to determine the extent of weathering of artificially evaporated crude oils and diesel. In addition to the pentacyclic biomarker C(29) and C(30) alphabeta-hopane, C(15) and C(16) sesquiterpanes might be alternative internal marker compounds to provide a direct way to estimate the depletion of oils, particularly diesels, in oil spill investigations. These findings may offer potential applications for both oil identification and oil-source correlation in cases where the tri- to pentacyclic biomarkers are absent due to refining or environmental weathering of oils.

Proton and carbon-13 NMR spectroscopic methods were developed for determining hydrogen and carbon contents in petroleum products. These methods are applicable to a wide of petroleum streams. A new reference standard, bis (trimethylsilyl) methane, BTMSM, is introduced fro both proton and carbon-13 NMR for the first time, which offers several advantages over those customarily employed. These methods are important for the calculation of the mass balance and hydrogen consumption in pilot plant studies. Unlike the ASTM D-5291 combustion method, the NMR methods also allow for the measurement of hydrogen and carbon content in low boiling fractions and those containing hydrogen as low as 1%. The NMR methods can also determine aromatic and aliphatic hydrogens carbons in a given sample without additional experimentation. The precision and accuracy of the newly developed NMR methods are compared with those of currently employed ASTM D-5291 combustion method. Using the proton NMR method, hydrogen content was determined in fifteen model compounds and sixty-eight petroleum fractions. The NMR and ASTM methods show an agreement within +5%for 48 out of a total number of 68 oil fractions. Using carbon-13 NMR, the carbon content was determined for four representative compounds and three fractions of crude oil. Both carbon-13 NMR and ASTM methods give comparable carbon content in model compounds and crude oil fractions. (author)

Gaharu oil extraction system developed by Nuclear Malaysia is a hydro-distillation system innovated from the tradition method and improvised with science and technology to enhance the process efficiency and safety. The main component of gaharu oil extraction system included the extraction vessel, condenser and collection decanter. Apart from the extraction unit, the gaharu oil extraction process also incorporated two major supporting systems. These systems are the liquefied petroleum gas (LPG) system and the water cooling system. The LPG system is solely used for heating the vessel, which contains a mixture of treated and grind gaharu bark and fluid, to produce steam. Meanwhile the water cooling system is used to supply the necessary cool water into the condenser unit and facilitate in the transformation of the mentioned steam into gaharu oil and distilled water. The dissipate water from this process will be channeled back into the water cooling ponds to let excess heat to be removed and allow the cool water to reuse again by the process. (author)

This article described an innovative forklift that responds to the oil industry's need for a safer, better and easier way to move long tubular products that cannot be carried high in the air. The Gator Jaw is a duplex pipe clamp attachment that secures to the Combilift forklift carriage. The clamp arm can be hydraulically moved upwards to allow the operator full use of the forks without interference from the hold down arm. The Combilift's platform is ideal for maneuvering oil and gas equipment close to the ground. Since it can travel sideways, the length of the load is not critical. The Gator Jaw's unique design makes it possible for one forklift to handle both skids and pallets. The C-Series product extends to the subsea oil and gas industry, which works with long loads such as oil drilling tools and pipe. The benefits include safer product handling, significant space savings, increased productivity and versatile indoor and outdoor use. The machines are available with a fuel-efficient liquefied petroleum gas (LPG) or diesel engine. 1 fig.

Several methods are available for the characterization of petroleum hydrocarbons. The TPHCWG (Total Petroleum Hydrocarbon Criteria Working Group) developed a method based on a silica column separation of aromatics and aliphatics and a GC-FID subdivision into equivalent-carbon fractions (EC) ('TPH-method'). This method was mainly developed for assessing human risks of oil compounds. Within NOBIS (Dutch Research program Biological In-situ Remediation), another method was developed based upon an equilibrium-experiment of the oil-polluted soil with water (column recirculation), which was further developed by TTE ('TTE-method'). This method uses measured water solubilities of individual oil components and GC-retention times yielding a subdivision of the hydrocarbons into compound classes that are relevant for assessing the remediation potential of the specific oil pollution. In this paper we present results of a research project in which we developed a new method, the 'OK-method' that combines these two procedures and allows a complete characterisation of the oil in terms of composition, (human) risks, volatility, solubility, plume behaviour (migration velocities of the soluble components) and aerobic degradation potential.

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

Will the 21. century be the petroleum challenge century? The petroleum problem is no longer the affair of experts and journalists, it challenges also governments and consumers in pressing terms. If there is today a petroleum problem, there is no oil or gas shortage for the moment. The cumulated oil and gas reserves would allow to face the demand of the century, with the condition that investments in exploration, field development, production, and back-end of oil and gas industries will be done in time. This book, written by specialists of energy economics and geopolitics shows up some of the key questions of our energy future. In particular, it invites us to never forget the basic heavy trends of the hydrocarbons sector in order to never be trapped by superficial extrapolations of short term phenomena. Content: heavy trend of oil prices at the 2020 prospects, natural gas take over?; oil and gas geopolitics: enough of hydrocarbons for the 21. century; Russia and Caspian sea oil and gas weight; China: a new strategic actor of the energy scene; influence of 'futures' market, of speculation, and of stocks on hydrocarbon prices; which future for LNG?; natural gas in the USA: towards a new foreign dependence.

Notice that most of the underground liquefied petroleum gas (LPG) storage caverns are constructed in unlined rock caverns (URCs), where the variability of hydraulic properties (in particular, hydraulic conductivity) has significant impacts on hydrologic containment performance. However, it is practically impossible to characterize the spatial distribution of these properties in detail at the site of URCs. This dilemma forces us to cope with uncertainty in our evaluations of gas containment. As a consequence, the uncertainty-based analysis is deemed more appropriate than the traditional deterministic analysis. The objectives of this paper are 1) to introduce a numerical first order method to calculate the gas containment reliability within a heterogeneous, two-dimensional unlined rock caverns, and 2) to suggest a strategy for improving the gas containment reliability. In order to achieve these goals, we first introduced the stochastic continuum representation of saturated hydraulic conductivity (Ks) of fractured rock and analyzed the spatial variability of Ks at a field site. We then conducted deterministic simulations to demonstrate the importance of heterogeneity of Ks in the analysis of gas tightness performance of URCs. Considering the uncertainty of the heterogeneity in the real world situations, we subsequently developed a numerical first order method (NFOM) to determine the gas tightness reliability at crucial locations of URCs. Using the NFOM, the effect of spatial variability of Ks on gas tightness reliability was investigated. Results show that as variance or spatial structure anisotropy of Ks increases, most of the gas tightness reliability at crucial locations reduces. Meanwhile, we compare the results of NFOM with those of Monte Carlo simulation, and we find the accuracy of NFOM is mainly affected by the magnitude of the variance of Ks. At last, for improving gas containment reliability at crucial locations at this study site, we suggest that vertical

The world is confronted with fossil fuel depletion and environmental degradation. The energy demand and pollution problems lead to research for an alternative renewable energy sources. Vegetable oils and biodiesel present a very promising alternative fuel to diesel. In this work, an experimental work was carried out to study the feasibility of using raw mahua oil (MO) as a substitute for diesel in dual fuel engine. A single cylinder diesel engine was modified to work in dual fuel mode and liquefied petroleum gas (LPG) was used as primary fuel and mahua oil was used as pilot fuel. The results show that the performance of the dual fuel engine at the injector opening pressure of 220 bar and the advanced injection timing of 30 degrees bTDC results in performance close to diesel base line (DBL) operation and lower smoke and oxides of nitrogen emission.

Research was conducted on conversion of coal to petroleum for the purpose of securing substitute liquid fuel. Recovery of hydrogen from the waste gas from the conversion process was explained, as were the conversion results from various coals produced in Japan. In coal liquefaction researches with the aim of manufacturing artificial petroleum, a report was made on each of the researches, i.e., the experiment results of coal liquefaction using various catalysts, manufacture of hydrogen by water gas reaction, catalytic action against coal paste, action of mixed oil and pressure against coal paste, result of hydrogen adding test for coal paste using an intermediate scale device, test result of secondary hydrogen addition for coal liquefied oil, and the test result of continuous secondary hydrogen addition for the liquefied oil. In the manufacture of fuel oil by hydro-cracking of coal or tar, a report was made on high pressure liquid phase hydrogenation of coal using a continuous testing device. Aromatic chemicals useful as chemical materials are supposed to be obtained by cutting inter-polymerized-unit bonding to make low molecules from the chemical structure of coal, removing surrounding radicals and simplifying it. A report was also made on the experiment of manufacturing coal chemicals by combination of high pressure liquid phase hydrogenation and hydro-dealkylation. (NEDO)

Vicissitudes in the Hong Kong oil market, 1980-97

International Nuclear Information System (INIS)

Chow, L.-H.

2000-01-01

Hong Kong, devoid of natural resources, has to import all the energy it consumes. Up to 1981, oil accounted for almost 100 per cent of the total primary energy requirement, of which about 59 per cent was used to generate electricity. Starting in 1982, the electricity sector switched to coal generation, leading to plummeting oil consumption. The conversion process was essentially completed by 1988. Local sales of oil products declined from 5.790 million kilolitres in 1981 to 3.470m kl in 1987, but climbed back to 5.157m kl in 1997; oil consumption stagnated between 1981 and 1997. This paper analyses the fluctuations in oil consumption during the period, covering use by the utility and non-utility sectors. Next, it deals with consumption of, and the factors involved in, the six major oil products, i.e. fuel oil, diesel, gasoline, liquefied petroleum gas, kerosene and jet fuel. Interestingly, bunker sales, including air and sea transport, rose noticeably during these years, partly offsetting the effect of slumping oil sales to the power plants and helping boost total oil demand in the 1990s. Lastly, a glimpse into the future of the Hong Kong oil market is taken. (author)

Management of oil sludge containing environmentally toxic elements is a major problem in crude oil processing industry. Oil sludge samples from the petroleum refinery plant in Melaka and crude oil terminal in Sarawak were analysed. The aim of present work is to study long term leaching behaviour of arsenic (As), cobalt (Co), chromium (Cr) and zinc (Zn) from oil sludge. Tank leaching test was carried out and the samples were analysed using inductively coupled plasma-mass spectrometry (ICP-MS). The results were studied using LeachXS software to plot the graphs of elements concentration in order to study the leaching behaviour of toxic elements in oil sludge. The long term leaching (100 years) modeling was calculated using equations referred to National Institute of Public Health and the Environment Bilthoven (RIVM) and the results were plotted for cumulative release in different areas of oil sludge. Tank leaching test of the oil sludge samples from petroleum refinery plant in Melaka showed concentrations of As, Co, Cr and Zn ranging from 0.205 to 1.102, 0.031-0.454, 0.016-0.086 and 0.409-8.238 mg/l, respectively while the concentrations of As, Co, Cr and Zn in oil sludge samples from crude oil terminal in Sarawak were in the range of 0.002-0.089, 0.001-0.033, 0.006-1.016 and 0.100-2.744 mg/l, respectively. On the other hand, results on cumulative release from the modeling of long term leaching (100 years) showed that As, Co, Cr and Zn concentrations were proportional to the quantity of oil sludge. In conclusion, during extrapolation of release of toxic elements using the data in the laboratory, several other factors were taken into account to suit environmental conditions such as soil moisture, the negative logarithm of the effective diffusion coefficient (pD e ) and temperature, while the long-term behaviour of As, Co, Cr and Zn was proportional to the quantity of oil sludge to be disposed off.

Full Text Available Cooking with dirty-burning fuels is associated with health risk from household air pollution. We assessed the prevalence of and factors associated with the use of cooking fuels, and attitudes and barriers towards use of liquefied petroleum gas (LPG. This was a cross-sectional, population-based survey conducted in 519 households in Lagos, Nigeria. We used a structured questionnaire to obtain information regarding choice of household cooking fuel and the attitudes towards the use of LPG. Kerosene was the most frequently used cooking fuel (n = 475, 91.5%; primary use n = 364, 70.1% followed by charcoal (n = 159, 30.6%; primary use n = 88, 17% and LPG (n = 86, 16.6%; primary use n = 63, 12.1%. Higher level of education, higher income and younger age were associated with LPG vs. kerosene use. Fuel expenditure on LPG was significantly lower than for kerosene ( N (Naira 2169.0 ± 1507.0 vs. N 2581.6 ± 1407.5. Over 90% of non-LPG users were willing to switch to LPG but cited safety issues and high cost as potential barriers to switching. Our findings suggest that misinformation and beliefs regarding benefits, safety and cost of LPG are important barriers to LPG use. An educational intervention program could be a cost-effective approach to improve LPG adoption and should be formally addressed through a well-designed community-based intervention study.

Millionaire underdogs: The Independent Petroleum Association of American and the politics of imported oil, 1921-1941

International Nuclear Information System (INIS)

Staggs, K.J.

1991-01-01

Smaller, usually non-integrated producers, or independents, demanded a protective tariff on imported petroleum, the one policy that would make the majors bear all the burdens of curtailment. In 1929 they created a national organization, the Independent Petroleum Association of America (IPPA), and after 1929 spent the next 12 years lobbying Congress and the Executive for some form of protective legislation. The independents argued that protectionism was necessary in order to maintain a competitive balance in the industry, and that if the majors were allowed to buy them out, the country would face high monopolistic prices for petroleum products. This study explains why the independent oil producers wanted protectionist legislation in the 1920s and 1930s, how they influenced oil policy, and what the short-term and long-run effects of the compromise over import controls were for America. It focuses particularly on the IPAA and makes use of its publications and of archival and manuscript collections, government documents, and trade journals that illuminate its thinking and its political activities

Exports of petroleum products, 1987

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 1987 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 22,200 m 3 /d in 1987, up 15% from 1986 levels. Exports of middle distillates and aviation fuel had the largest gains in 1987. Export prices for light petroleum products stayed relatively close to USA spot prices. The heavy fuel oil price was below the New York spot price in the beginning of 1987 but remained close for the rest of the year. Canada's petroleum products exports were made to 5 countries while imports came from at least 13 countries. The USA remained Canada's largest trading partner in petroleum products. Exports to Japan and the Far East rose ca 60% over 1986. Product outturns for export were 9% of total Canadian refinery throughput. Exports of aviation turbine fuel from Ontario began in April 1987. The top single exporter in Canada was Irving Oil Ltd. with 2,485,000 m 3 . Irving was also the top exporter in 1986. 11 figs., 4 tabs

Causes for an asymmetric relation between the price of crude oil and refined petroleum products

Kaufmann, R.K.; Laskowski, C.

2005-01-01

We revisit the issue of asymmetries in the relation between the price of crude oil and refined petroleum products in the United States. An econometric analysis of monthly data indicates that the asymmetric relationship between the price of crude oil and motor gasoline is generated by refinery utilization rates and inventory behavior. The asymmetric relation between the price of crude oil and home heating oil probably is generated by contractual arrangements between retailers and consumers. Together, these results imply that price asymmetries may be generated by efficient markets. Under these conditions, there is little justification for policy interventions to reduce or eliminate price asymmetries in motor gasoline and home heating oil markets. (author)

We evaluate the relative impact of petroleum spill and storm surge on near-shore wetland loss by quantifying the lateral movement of coastal shores in upper Barataria Bay, Louisiana (USA), between June 2009 and October 2012, a study period that extends from the year prior to the Deepwater Horizon spill to 2.5 years following the spill. We document a distinctly different pattern of shoreline loss in the 2 years following the spill, both from that observed in the year prior to the spill, during which there was no major cyclonic storm, and from change related to Hurricane Isaac, which made landfall in August 2012. Shoreline erosion following oiling was far more spatially extensive and included loss in areas protected from wave-induced erosion. We conclude that petroleum exposure can substantially increase shoreline recession particularly in areas protected from storm-induced degradation and disproportionally alters small oil-exposed barrier islands relative to natural erosion.

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

An analysis of the specific consumption of energy and of the comparative costs of the use of the Liquefied Petroleum Gas (LPG), eucalyptus firewood and coffee husks as sources of energy in the drying of coffee (Coffea arabica L.) was done. Dryers of intermittent crossed flows were used with temperature of the drying air of 60 deg C. The drying in yard was used as witness. It is ended that the use in the different form of energy did not alter the final quality of the product, and that LPG is more efficient in terms of specific consumption of energy that the husks of coffee and eucalyptus firewood, even so, of cost approximately four times or more higher than that of the other fuels.

Directly liquefied biomass (by the PERC process) has been upgraded to gasoline and diesel by the following steps: - Extraction with decahydrohaphtalen, simulating extraction with gasoil. - Hydroprocessing of the extracted oil with a sulphided catalyst. - Distillation and catalytic cracking of the hydroprocessed oil. The yields of gasoline and diesel are 9.9 and 16.5 weight percent respectively of fed liquefied biomass. The process is not optimized. Methylsubstituted phenols present in the liquefied biomass have been hydroprocessed to eliminate the oxygen content. The reaction may either be a direct elimination of oxygen or an elimination preceeded by hydrogenation which consumes large amounts of hydrogen. By running the reaction in an environment with a low sulphur content and with a sulphided catalyst, it is possible to carry out direct hydrodeoxygenation. During the two year period, results have been achieved according to the proposed program.

1995-02-01

This report on the Norwegian petroleum activity in 1994 is published by the Royal Ministry of Industry and Energy. Production to the end of 1994 totaled 1.63 billion scm oe. At 31 Dec 1994, total reserves on the Norwegian continental shelf comprised 1.34 billion scm oe of oil, 1.35 billion scm oe of gas and 0.1 billion scm oe of NGLs. The net increment in oil and gas during 1994 was about 115 million scm oe. Twenty-seven exploration wells, including 22 wildcats and five appraisal wells, were completed or temporarily abandoned on the Norwegian continental shelf in 1994. Governmental approval was given for developing the second phase of the Ekofisk field, the Vigdis and Snorre Lunde oil fields, and two smaller formations on the Veslefrikk field. Investment in petroleum operations totaled about NOK 50 billion. Norwegian oil and gas production came to about 180 million scm oe. At present levels of output, Norway's petroleum resources are sufficient to support production of oil for 20 years and of gas for 115 years. The estimated value of Norwegian petroleum exports in 1994 is NOK 114 billion, representing about 34% of the country's total export earnings. State revenues from taxes and royalties on petroleum operations came to about NOK 23.7 billion, or eight per cent of total government revenues. 24 figs., 13 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 m 3 /d in 1989, down 5% from 1988 levels. Motor gasoline shipments showed the largest decrease, down 1,500 m 3 to 7,700 m 3 /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 m 3 /d, compared to 18,400 m 3 /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 m 3 . 24 figs., 4 tabs

We assessed temporal and spatial patterns of chronic oiling of seabirds in California during 2005-2010, using data on: (1) live oiled birds reported to the Oiled Wildlife Care Network (OWCN) from throughout the state, and (2) dead oiled birds found during systematic monthly beached-bird surveys in central California. A mean of 245 (± 141 SD) live miscellaneous oiled birds (not associated with known oil spills) were reported to the OWCN per year, and 0.1 oiled dead birds km(-1) per month were found on beach surveys in central California. Chemical fingerprinting of oiled feathers from a subset of these birds (n=101) indicated that 89% of samples tested were likely from natural petroleum seeps off southern and central California. There was a pronounced peak during late winter in the number of oiled birds reported in southern California, which we theorize may be related to large storm waves disturbing underwater seeps.

Human Resource Local Content in Ghana's Upstream Petroleum Industry

Science.gov (United States)

Benin, Papa

Enactment of Ghana's Petroleum (Local Content and Local Participation) Regulations, 2013 (L.I. 2204) was intended to regulate the percentage of local products, personnel, financing, and goods and services rendered within Ghana's upstream petroleum industry value chain. Five years after the inception of Ghana's upstream oil and gas industry, a gap is evident between the requirements of L.I. 2204 and professional practice. Drawing on Lewin's change theory, a cross-sectional study was conducted to examine the extent of differences between the prevailing human resource local content and the requirements of L.I. 2204 in Ghana's upstream petroleum industry. The extent to which training acquired by indigenous Ghanaians seeking jobs in Ghana's oil fields affects the prevalent local content in its upstream petroleum industry was also examined. Survey data were collected from 97 management, technical, and other staff in 2 multinational petroleum companies whose oil and gas development plans have been approved by the Petroleum Commission of Ghana. To answer the research questions and test their hypotheses, one-way ANOVA was performed with staff category (management, technical, and other) as the independent variable and prevalent local content as the dependent variable. Results indicated that prevailing local content in Ghana's upstream petroleum industry meets the requirements of L.I. 2204. Further, training acquired by indigenous Ghanaians seeking jobs in Ghana's oil fields affects the prevalent local content in its offshore petroleum industry. Findings may encourage leaders within multinational oil companies and the Petroleum Commission of Ghana to organize educational seminars that equip indigenous Ghanaians with specialized skills for working in Ghana's upstream petroleum industry.

Boom times : Canada's crude petroleum industry : analysis in brief

International Nuclear Information System (INIS)

Rowat, M.R.

This document examined the trends in crude oil prices, the production and exports of Canada's crude petroleum industry, and Canada's imports of crude petroleum. As an exporter and importer of crude oil, Canada's petroleum industry is currently experiencing economic prosperity as a result of high oil prices combined with high global demand for oil. This document reviewed industry activity for 2005 and addressed the reasons for the first decline in Canadian crude oil production in 6 years. A quick review of soaring crude oil prices, supply and shortages was also presented. A review of exports revealed that since 1995, the United States has received 99 per cent of Canadian exports. Although production activity is occurring in 7 provinces, the biggest participant is Alberta, followed by Saskatchewan. In 2005, Canada produced 136.4 million cubic metres of crude petroleum, of which two-thirds came from Alberta. Saskatchewan contributed 18 per cent of total Canadian crude oil production, while offshore oil rigs in Newfoundland and Labrador contributed 13 per cent. The vast oil sands resource accounted for 42 per cent of the province's total production. Alberta oil export is piped entirely into the United States. In 2005, even with a slight drop in exports, Canadian oil exporters received $30 billion for their products, up from $25 billion the year before. Canada also supplied nearly 10 per cent of the American crude oil needs. According to the National Energy Board, Canadian refineries are approaching capacity. Canada's 19 refineries, which have a capacity of 320,000 cubic metres per day, operated at 92 per cent of capacity in 2005 to meet the needs of the domestic market. More imported petroleum was refined than Canadian sourced petroleum. In 2005, the gas and oil industry saw historically high profits, taxes paid and investments. 6 refs., 5 figs

The oil and gas equipment and services market in Nigeria

International Nuclear Information System (INIS)

2003-01-01

The oil and gas market in Nigeria is being expanded by the Nigerian government over the 2003-2010 period through increased exploration and production (E and P) in new areas. Other measures being implemented are the improvements of structural flaws that hamper industry growth, the modernization of the weak downstream sector, and attempts to attract foreign investment and technologies required for petroleum development. In 2001, it was estimated that the market for oil and gas equipment in Nigeria was approximately 1.03 billion dollars, and is expected to reach 1.15 billion dollars in 2002. In deep-sea areas, major offshore E and P projects are being planned by large oil multinationals. The implementation of several gas-related E and P operations and major liquefied natural gas (LNG) and gas-to-liquid (GTL) projects are being supported by the government of Nigeria to develop the natural gas sector. Onshore and offshore exploration, surveying and geophysical prospecting, drilling equipment, facilities maintenance, deepwater E and P, equipment for LNG/GTL facilities, enhanced recovery equipment and services, gas re-injection technology, pipelines, and the refinery sector are all areas where Canadian equipment and service suppliers could benefit from opportunities in Nigeria. One of the most prominent foreign player in the Nigerian market is Royal Dutch Shell. As far as the offshore deepwater E and P sub-sector, the three major players are Shell, ChevronTexaco, and ExxonMobil. The Nigerian government advocate in upstream and downstream oil industries in the country is Nigeria National Petroleum Corporation (NNPC). The primary domestic end-users of oil and gas equipment and services are member companies of the Nigerian Association of Indigenous Petroleum Exploration Companies (NAIPEC). Canadian companies are encouraged to form joint venture partnerships in oil and gas projects, as foreign majors operating in Nigeria tend to rely on the skills and expertise of foreign

Carcinogenicity of petroleum lubricating oil distillates: effects of solvent refining, hydroprocessing, and blending.

Science.gov (United States)

Halder, C A; Warne, T M; Little, R Q; Garvin, P J

1984-01-01

Certain refining processes were investigated to determine their influence on the dermal carcinogenic activity of petroleum-derived lubricating oil distillates. Specifically, the effects of solvent refining, hydroprocessing, a combination of both processes, and the blending of oils processed using each technique were evaluated in standard mouse skin-painting bioassays. The refining process used as well as the level or severity of treatment greatly influenced the carcinogenic outcome of processed lubricating oils. Solvent refining at severities normally used appeared to eliminate carcinogenicity. In contrast, hydroprocessing alone at mild levels of treatment was successful only in reducing the carcinogenic potency; severe hydroprocessing conditions were necessary to eliminate carcinogenic activity without the use of additional refining processes. Carcinogenic activity could also be eliminated by following moderate solvent refining with mild hydroprocessing. Blending of hydroprocessed oils with solvent-refined oils resulted in a substantial reduction or even elimination of carcinogenic activity. However, the degree of protection obtained varied with the particular distillates used and appeared largely dependent on the inherent biological activity of the hydroprocessed oil.

1989-12-01

In anticipation of the commercialization of its shale oil retorting and upgrading process, Unocal Corp. conducted a testing program aimed at better defining potential health impacts of a shale industry. Acute toxicity studies using rats and rabbits compared the effects of naphtha, Jet-A, JP-4, diesel and "residual" distillate fractions of both petroleum derived crude oils and hydrotreated shale oil. No differences in the acute oral (greater than 5 g/kg LD50) and dermal (greater than 2 g/kg LD50) toxicities were noted between the shale and petroleum derived distillates and none of the samples were more than mildly irritating to the eyes. Shale and petroleum products caused similar degrees of mild to moderate skin irritation. None of the materials produced sensitization reactions. The LC50 after acute inhalation exposure to Jet-A, shale naphtha, (greater than 5 mg/L) and JP-4 distillate fractions of petroleum and shale oils was greater than 5 mg/L. The LC50 of petroleum naphtha (greater than 4.8 mg/L) and raw shale oil (greater than 3.95 mg/L) also indicated low toxicity. Results demonstrate that shale oil products are of low acute toxicity, mild to moderately irritating and similar to their petroleum counterparts. The results further demonstrate that hydrotreatment reduces the irritancy of raw shale oil.

1997-01-01

As African countries continue a slow drift towards democratic government and market economics, the continent is increasingly attractive to international oil and gas companies. Though Africa remains politically diverse, and its volatile politics remains a major barrier to petroleum companies, a number of recent developments reflect its growing significance for the industry. Among recent projects and events reflecting changes in Africa: oil and gas exporter Algeria has invited foreign oil companies to help develop major gas discoveries, with a view to boosting exports to Europe; oil and gas producer Egypt invited foreign companies to explore in the Nile Delta region, and the result appears to be a flowering world scale gas play; west African offshore exploration has entered deep water and new areas, and a number of major projects are expected in years to come; Nigeria's reputation as a difficult place to operate has been justified by recent political and civil events, but a long-planned liquefied natural gas (LNG) export plant is being built there; South Africa, which has returned to the international scene after years of trade isolation because of apartheid, is emerging as a potential driver for energy industry schemes throughout the continent.

Lee, Jin-Yong; Cho, Byung Wook

2008-10-01

SummaryThe occurrence of submarine groundwater discharge (SGD) as well as its supply of many nutrients and metals to coastal seawaters is now generally known. However, previous studies have focused on the chemical and radiological analysis of groundwater, surface seawater, shallow marine sediments and their pore waters, as well as the measurement of upward flow through the marine sediments, as end members of the discharge process. In this study, chemical and isotopic analysis results of marine subsurface waters are reported. These were obtained from deep boreholes of an undersea liquefied petroleum gas (LPG) storage cavern, located about 8 km off the western coast of Korea. The cavern is about 130-150 m below the sea bottom, which is covered by a 4.8-19.5 m silty clay stratum. An isotopic composition (δ 2H and δ 18O) of the marine subsurface waters falls on a mixing line between terrestrial groundwater and seawater. Vertical EC profiling at the cavern boreholes revealed the existence of a fresh water zone. An increase in the contents of ferrous iron and manganese and a decrease in levels of nitrate, bicarbonate and cavern seepage were recorded in August 2006, indicating a decreased submarine groundwater flux originating from land, mainly caused by an elevated cavern gas pressure. It is suggested in this study that the main source of fresh waters in the man-made undersea cavern is the submarine groundwater discharge mainly originating from the land.

Petroleum Systems and Assessment of Undiscovered Oil and Gas in the Raton Basin - Sierra Grande Uplift Province, Colorado and New Mexico - USGS Province 41

Higley, Debra K.

2007-01-01

Introduction The purpose of the U.S. Geological Survey's (USGS) National Oil and Gas Assessment is to develop geologically based hypotheses regarding the potential for additions to oil and gas reserves in priority areas of the United States. The USGS recently completed an assessment of undiscovered oil and gas resources of the Raton Basin-Sierra Grande Uplift Province of southeastern Colorado and northeastern New Mexico (USGS Province 41). The Cretaceous Vermejo Formation and Cretaceous-Tertiary Raton Formation have production and undiscovered resources of coalbed methane. Other formations in the province exhibit potential for gas resources and limited production. This assessment is based on geologic principles and uses the total petroleum system concept. The geologic elements of a total petroleum system include hydrocarbon source rocks (source rock maturation, hydrocarbon generation and migration), reservoir rocks (sequence stratigraphy and petrophysical properties), and hydrocarbon traps (trap formation and timing). The USGS used this geologic framework to define two total petroleum systems and five assessment units. All five assessment units were quantitatively assessed for undiscovered gas resources. Oil resources were not assessed because of the limited potential due to levels of thermal maturity of petroleum source rocks.

A study of the effects of enhanced oil recovery agents on the quality of Strategic Petroleum Reserves crude oil. [Physical and chemical interactions of Enhanced Oil Recovery reagents with hydrocarbons present in petroleum

Energy Technology Data Exchange (ETDEWEB)

Kabadi, V.N.

1992-10-01

The project was initiated on September 1, 1990. The objective of the project was to carry out a literature search to estimate the types and extents of long time interactions of enhanced oil recovery (EOR) agents, such as surfactants, caustics and polymers, with crude oil. This information is necessary to make recommendations about mixing EOR crude oil with crude oils from primary and secondary recovery processes in the Strategic Petroleum Reserve (SPR). Data were sought on both adverse and beneficial effects of EOR agents that would impact handling, transportation and refining of crude oil. An extensive literature search has been completed, and the following informations has been compiled: (1) a listing of existing EOR test and field projects; (2) a listing of currently used EOR agents; and (3) evidence of short and long term physical and chemical interactions of these EOR-agents with hydrocarbons, and their effects on the quality of crude oil at long times. This information is presented in this report. Finally some conclusions are derived and recommendations are made. Although the conclusions are based mostly on extrapolations because of lack of specific data, it is recommended that the enhancement of the rates of biodegradation of oil catalyzed by the EOR agents needs to be further studied. There is no evidence of substantial long term effects on crude oil because of other interactions. Some recommendations are also made regarding the types of studies that would be necessary to determine the effect of certain EOR agents on the rates of biodegradation of crude oil.

The reporting universe includes those petroleum sectors in primary supply. Included are: petroleum refiners, motor gasoline blends, operators of natural gas processing plants and fractionators, inter-PAD transporters, importers, and major inventory holders of petroleum products and crude oil. When aggregated, the data reported by these sectors approximately represent the consumption of petroleum products in the United States.

Options for reducing oil content of sludge from a petroleum wastewater treatment plant.

Science.gov (United States)

Kwon, Tae-Soon; Lee, Jae-Young

2015-10-01

Wastewater treatment plants at petroleum refineries often produce substantial quantities of sludge with relatively high concentrations of oil. Disposal of this waste is costly, in part because the high oil content requires use of secure disposal methods akin to handling of hazardous wastes. This article examines the properties of oily sludge and evaluates optional methods for reducing the oil content of this sludge to enable use of lower cost disposal methods. To reduce the oil content or break the structure of oily sludge, preliminary lab-scale experiments involving mechanical treatment, surfactant extraction, and oxidation are conducted. By applying surfactants, approximately 36% to 45% of oils are extracted from oily sludge. Of this, about 33% of oils are rapidly oxidised via radiation by an electron beam within 10 s of exposure. The Fenton reaction is effective for destruction of oily sludge. It is also found that 56% of oils were removed by reacting oily sludge with water containing ozone of 0.5 mg l(-1) over a period of 24 h. Oxidation using ozone thus can also be effectively used as a pretreatment for oily sludge. © The Author(s) 2015.

Suggestive evidence on the origin of petroleum and oil shale

Energy Technology Data Exchange (ETDEWEB)

Jones, J C

1923-01-01

Oil shales and coals originated in fresh water muds that contained large amounts of spores, algae, and other nonwoody vegetable material. This organic debris was partly decomposed by bacterial action but not enough to increase the percentage of fats by removal of other plant substances. By contrast, petroleum was formed by thorough decomposition of nonfatty material in salt water. The main difference in bacterial action was due to differences in the saline content of the water in which the organic material was deposited. In fresh water, the amount of decay was small, whereas in salt water it was nearly complete.

Crude oil may cause adverse dermal effects therefore dermal exposure is an exposure route of concern. Galea et al. (2014b) reported on a study comparing recovery (wipe) and interception (cotton glove) dermal sampling methods. The authors concluded that both methods were suitable for assessing dermal exposure to oil-based drilling fluids and crude oil but that glove samplers may overestimate the amount of fluid transferred to the skin. We describe a study which aimed to further evaluate the wipe sampling method to assess dermal exposure to crude oil, with this assessment including extended sample storage periods and sampling efficiency tests being undertaken at environmental conditions to mimic those typical of outdoor conditions in Saudi Arabia. The wipe sampling method was then used to assess the laboratory technicians' actual exposure to crude oil during typical petroleum laboratory tasks. Overall, acceptable storage efficiencies up to 54 days were reported with results suggesting storage stability over time. Sampling efficiencies were also reported to be satisfactory at both ambient and elevated temperature and relative humidity environmental conditions for surrogate skin spiked with known masses of crude oil and left up to 4 h prior to wiping, though there was an indication of reduced sampling efficiency over time. Nineteen petroleum laboratory technicians provided a total of 35 pre- and 35 post-activity paired hand wipe samples. Ninety-three percent of the pre-exposure paired hand wipes were less than the analytical limit of detection (LOD), whereas 46% of the post-activity paired hand wipes were less than the LOD. The geometric mean paired post-activity wipe sample measurement was 3.09 µg cm-2 (range 1.76-35.4 µg cm-2). It was considered that dermal exposure most frequently occurred through direct contact with the crude oil (emission) or via deposition. The findings of this study suggest that the wipe sampling method is satisfactory in quantifying

In 1998, the Petroleum Technology Alliance of Canada (PTAC) and the Canadian Association of Petroleum Producers (CAPP) launched an important research project for the oil and gas industry entitled A Fraction-Specific Toxicity and Derivation of Recommended Soil Quality Guidelines for Crude Oil in Agricultural Soils. The objective was to generate useful and relevant data that could be used to develop soil quality guidelines for petroleum hydrocarbon residuals in agricultural soils. The oil used in the study was Federated crude oil which was fractionated into four fractions using a distillation method. The fraction-based approach was used to support ecologically-relevant, risk-based, soil quality criteria for the protection of environmental health. This paper presented the nominal carbon number and boiling point ranges of these fractions and described the distillation procedures for producing the fractions from the Federated crude oil. The paper also presented the detailed chemical characterization results of each distillation fraction. The toxicity of the crude oil mixture to plants and soil invertebrates was also assessed using standardized toxicity tests. Tests were also conducted to assess the toxicity of fractions of the crude oil and the toxic interactions of the fractions responsible for a significant proportion of the toxicity. Phase 2 of the project was designed to determine if hydrocarbon residuals exceeding 1000 μg/g and weathered for short or long periods of time, posed an ecotoxicological risk or impaired soil physical, chemical and biological properties such that productivity of the agricultural soils was compromised. The objectives of phase 2 were to amend differently textured soils in field plots at sites with fresh crude oil and to monitor their toxicity to terrestrial organisms using laboratory-based ecotoxicity tests. The study showed that because of the nature of the chemical composition of hydrocarbons (such as boiling points, nominal carbon range

In exploration and production of petroleum is generated solid waste different and components other. The petroleum oily sludge is a complex mix of components different (water, oil and solid). The petroleum oily sludge generally has other residues and is formed during production and operations, transport, storage and petroleum refining (atmospheric residue, vacuum residue and catalytic cracking residue). However, according to its origin, the compositions can be found quite varied for sludge. Observing the process steps production and refining is possible to locate its main sources and percentage contributions in terms of waste generation. The elemental analysis was performed with oily sludge from region and it showed different composition. For carbon element and hydrogen, small differences was observed, but for was observed greater differences for Oxygen element. The sludge has different inorganic and organic composition. The sludge from oil water separator (OWS) 2 showed a greater amount of oil (94.88%), this may indicate a residue of aggregate high for petroleum industry. In analysis of Saturates, Aromatics, Resins and Asphaltenes (SARA), the sludge from unloading showed amount high of saturates. The inorganic material separated from sludge was characterized and sludge from OWS 2 had high amount sulfur (41.57%). The sludge analyzed showed organic components high values, so it can be treated and reprocessed in process units petroleum industry.

Geopolitics of petroleum

International Nuclear Information System (INIS)

Sebille-Lopez, Ph.

2006-01-01

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.)

1997-01-01

The Third Millennium International Petroleum Conference is briefly reported at which the competitive challenges faced by the upstream industry were considered. An oil industry wanting to be successful in facing these challenges was perceived by Mobil Oil's Vice-President of Global Business Strategy as requiring the following attributes: the ability to partner with others; a truly global perspective; a balanced portfolio to manage risk; strong technological orientation; the capacity to attract an innovative work-force. The new background of energy geopolitics brought about by the integration of Russia, the CIS countries, China and India into the world market economy, was sketched by the former Exploration Director of Premier Oil. Attention was drawn to the concern and tension being created in the Middle East by the restructuring of oil and gas development arising out of the current US containment foreign policy. This policy is changing the geographical focus and regional strategies of US oil companies and contractors. Some examples of these were presented in papers by other US participants. Contributions from natioan producing companies from other countries demonstrated the opportunities offered to foreign countries by increased liberalisation. (UK)

Future petroleum energy resources of the world

2002-01-01

Is the world running out of oil? Where will future oil and gas supplies come from? To help answer these questions, in 2000 the U.S. Geological Survey completed a new world assessment, exclusive of the United States, of the undiscovered conventional oil and gas resources and potential additions to reserves from field growth.2 One hundred and twenty-eight provinces were assessed in a 100 man-year effort from 1995-2000. The assessed provinces included 76 priority provinces containing 95% of the world's discovered oil and gas and an additional 52 "boutique" provinces, many of which may be highly prospective. Total Petroleum Systems (TPS) were identified and described for each of these provinces along with associated Assessment Units (AU) that are the basic units for assessing undiscovered petroleum. The assessment process coupled geologic analysis with a probabilistic methodology to estimate remaining potential. Within the 128 assessed provinces were 159 TPS and 274 AU. For these provinces, the endowment of recoverable oil-which includes cumulative production, remaining reserves, reserve growth, and undiscovered resources-is estimated at about 3 trillion barrels of oil (TBO). The natural gas endowment is estimated at 2.6 trillion barrels of oil equivalent (TBOE). Oil reserves are currently 1.1 TBO; world consumption is about .028 TBO per year. Natural gas reserves are about 0.8 TBOE; world consumption is about 0.014 TBOE per year. Thus, without any additional discoveries of oil, gas or natural gas liquids, we have about 2 TBOE of proved petroleum reserves. Of the oil and gas endowment of about 5.6 TBOE, we estimate that the world has consumed about 1 TBOE, or 18%, leaving about 82% of the endowment to be utilized or found. Half of the world's undiscovered potential is offshore. Arctic basins with about 25% of undiscovered petroleum resources make up the next great frontier. An additional 279 provinces contain some oil and gas and, if considered, would increase the oil

After some basic considerations of petroleum demand, petroleum supply and petroleum reserves, the article gives a survey of the various methods of obtaining petroleum. The use of energy in the form of steam and electricity in the previously used processes and in conventional deposits requires up to 50% of the energy contained in the oil obtained. Now unconventional sources of petroleum (tertiary petroleum, heavy fractions and shale oil) could become of interest to West Germany in the near future. The economy of production can be determined by the energy source used, to a large extent. A series of possibilities are discussed for using nuclear steam raising systems for this purpose. (UA) [de

The petroleum sector is extremely important to Norway. The industry is responsible for one fourth of all value creation in the country and more than one fourth of the state's revenues. It is currently Norway's largest industry, and the spillover effects to other industries are substantial. Norway ranks as the world's third largest exporter of oil and the eighth largest oil producer. Less than one third of the estimated petroleum reserves Norway has have been produced. The level of activity on the Norwegian continental shelf was very high in 2005. The number of producing fields was 50, and these fields produced 3 million barrels of oil (including NGL and condensate) per day and 85 billion standard cubic metres (scm) gas, for a total production saleable petroleum of 257 million scm of oil equivalents. Resource management is conducted through the models of cooperation and competition. Annual licensing rounds are held by the authorities where companies are given access to new exploration areas. The interest in the 19th licensing round in 2005 was considerable, indicating a continuous high interest in the Norwegian continental shelf. The Norwegian Petroleum Directorate estimates for the future a gradual increase in the petroleum production up until 2011, and a gradual fall thereafter. Gas production is expected to increase until 2013. Gas production represents 35 percent of the total production in 2006. It is expected that by 2013 it will represent 50 percent of the total. Other aspects accounted for include government petroleum revenues, environmental considerations, petroleum resources and overviews of fields in production, fields where production has ceased and fields under development

Utilization of oil palm empty fruit bunches (EFB) in the production of bio-phenolic resin is an alternative way to reduce the dependency of petroleum-based phenol. In this study, resol type bio-phenolic resin (BPR) was synthesized from EFB fibers using sulfuric acid as the catalyst to produce liquefied empty fruit bunches (LEFB) followed by resinification reaction with formaldehyde in alkaline condition. The SEM image of LEFB residue showed separation of fiber bundles into individual fibers. This indicate that lignin was destroyed during the liquefaction process. The increased of formaldehyde/LEFB molar ratio has resulted an increase of viscosity, solid content and pH of the resin. The obtained FTIR spectra confirmed that functional groups of BPR resins was almost similar with commercial resin.

Subsurface ecosystems. Oil triggered life. Opportunities for the petroleum industry

Energy Technology Data Exchange (ETDEWEB)

Van der Kraan, G.M.

2010-10-05

As it is getting more difficult to retrieve oil from the subsurface, there is a renewed interest from the petroleum industry regarding microbial processes in oil-water systems, like oil reservoirs and their associated refineries. Oil fields are specific ecosystems, they are oxygen depleted, contain a variety of hydrocarbons and often have elevated temperatures and pressures. Through human exploitation, active changes in oil field ecosystems are induced. An example is seawater injection to displace oil. Seawater injection causes a decrease in temperature and induces the growth of sulphate reducing bacteria due to the introduction of sulphate and thereby as a consequence the production of harmful H2S. The current idea is that microorganisms detected in, for example, production water from an oil well, hold additional information on the oil field itself and the processes that are occurring in this oil field during exploitation of the field, so-called 'Biomonitoring'. Through the application of 'smart well' technology, viz. clever exploitation of the oil field, more oil can be retrieved from the field. This however requires new information sources from the field itself. Biotechnology might offer an additional information source. Also it is expected that growth of microorganisms in oil field can plug so called 'thief zones' in oil fields, which forces injected water to take an alternative route and thereby displacing more of the oil. This process however has first to be understood on the pore level. This thesis investigates the concept of 'biomonitoring'. To this purpose the microbial community of water and core samples taken from various oil fields, their separation facilities, and other subsurface environments have been investigated with the use of various molecular techniques like denaturing gradient gel electrophoresis (DGGE) and clone library construction of 16S rRNA gene fragments. The presence of several species can be

Application of computational chemistry methods to obtain thermodynamic data for hydrogen production from liquefied petroleum gas

Full Text Available The objective of this study was to estimate thermodynamic data, such as standard enthalpy, entropy and Gibbs free energy changes of reaction and, consequently, chemical equilibrium constants, for a reaction system describing the hydrogen production from Liquefied Petroleum Gas (LPG. The acquisition of those properties was made using computational chemistry methods and the results were compared with experimental data reported in the literature. The reaction system of steam reforming of LPG was reported as a set of seven independent reactions involving the chemical species n-C4H10, C3H8, C2H6, C2H4, CH4, CO2, CO, H2O, H2 and solid carbon. Six computational approaches were used: Density Functional Theory (DFT employing Becke's three parameter hybrid exchange functional, and the Lee-Yang-Parr correlation functional (B3LYP using the 6-31G++(d,p basis set and the composite methods CBS-QB3, Gaussian-1 (G1, Gaussian-2 (G2, Gaussian-3 (G3 and Gaussian-4 (G4. Mole fractions of the system components were also determined between 873.15 and 1173.15 K, at 1 atm and a feed with a stoichiometric amount of water. Results showed that the hybrid functional B3LYP/6-31G++(d,p, G3 and G4 theories were the most appropriated methods to predict the properties of interest. Gaussian-3 and Gaussian-4 theories are expected to be good thermodynamic data predictors and the known efficient prediction of vibrational frequencies by B3LYP is probably the source of the good agreement found in this study. This last methodology is of special interest since it presents low computational cost, which is important when more complex molecular systems are considered.

Todays, petroleum companies consider that despite the constant increase of petroleum consumption, petroleum will remain the main energy source for at least 40 years. However, after the Iraq conflict, new regional situations are changing. China, for instance, with its growing up demand, will change the physiognomy of the oil market. In parallel, from Indonesia to Africa, petroleum and religion interfere and explain the new conflict areas. As for the US strategy, which is not limited to the energy paradigm, it largely integrates energy in the main lines of its diplomacy, from the 'Wide Middle East' to the 'Sahel initiative', and in its position with respect to Venezuela

This paper reports on history and development of International Petroleum Contracts. The emphasis in petroleum exploration has steadily shifted away from the domestic oil patch and toward the international arena. Today an estimated 577.3 billion bbl, or approximately 83% of the world's proven oil reserves, lie outside the western hemisphere. The distribution of these proven oil reserves can be broken down into three major socioeconomic categories - developed market economies, centrally planned economies, and developing countries - indicating that fully 76.7% of the world's proven oil reserves occur in developing countries. As multinational oil companies come into contact with the various host countries around the world, their course of action, and the course of the host country's reaction to them, are unfortunately colored by events that proceeded the initial contact

Petroleum apocalypse

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 organic mailer rich Oligocene Menilite black shales and mudstones are widely distributed in the Carpathian Overthrust region of southeastern Poland and have excellent hydrocarbon generation potential, according to TOC, Rock-Eval, and petrographic data. Extractable organic matter was characterized by an equable distribution of steranes by carbon number, by varying amounts of 28,30-dinor-hopane, 18??(H)-oleanane and by a distinctive group of C24 ring-A degraded triterpanes. The Menilite samples ranged in maturity from pre-generative to mid-oil window levels, with the most mature in the southeastern portion of the study area. Carpathian petroleum samples from Campanian Oligocene sandstone reservoirs were similar in biomarker composition to the Menilite rock extracts. Similarities in aliphatic and aromatic hydrocarbon distributions between petroleum asphaltene and source rock pyrolyzates provided further evidence genetically linking Menilite kerogens with Carpathian oils.

Magnetic liquefier for hydrogen

International Nuclear Information System (INIS)

1992-01-01

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

We assessed the exposure levels of noise, estimated prevalence, and identify risk factors of noise-induced hearing loss (NIHL) among male workers with a cross-sectional study in a liquefied petroleum gas cylinder infusion factory in Taipei City. Male in-field workers exposed to noise and administrative controls were enrolled in 2006 and 2007. Face-to-face interviews were applied for demographics, employment history, and drinking/smoking habit. We then performed the measurements on noise levels in field and administration area, and hearing thresholds on study subjects with standard apparatus and protocols. Existence of hearing loss > 25 dBHL for the average of 500 Hz, 1 kHz, and 2 kHz was accordingly determined for NIHL. The effects from noise exposure, predisposing characteristics, employment-related factors, and personal habits to NIHL were estimated by univariate and multivariate logistic regressions. A total of 75 subjects were involved in research and 56.8% of in-field workers had NIHL. Between the in-field and administration groups, hearing thresholds on the worse ear showed significant differences at frequencies of 4 k, 6 k, and 8 kHz with aging considered. Adjusted odds ratio for field noise exposure (OR=99.57, 95% CI: 3.53, 2,808.74) and frequent tea or coffee consumption (OR=0.03, 95% CI: 0.01, 0.51) were found significant. Current study addressed NIHL in a specific industry in Taiwan. Further efforts in minimizing its impact are still in need.

Full Text Available In order to produce petroleum alternatives from biomass, a significant amount of research has been focused on oils from microalgae due to their origin, which would not affect food availability. Nanoporous hybrid catalysts composed of ns Al2O3 and zeolites have been proven to be very useful compared to traditional catalysts in hydrotreating (HT, hydrocracking (HC, and catalytic cracking (CC of large molecules. To evaluate the reaction scheme and products from model isoprenoid compounds of microalgae oil, nanoporous hybrid catalyst technologies (CC: ns Al2O3/H-USY and ns Al2O3/H-GaAlMFI; HC: [Ni-Mo/γ-Al2O3]/ns Al2O3/H-beta were studied. The major product from CC on ns Al2O3/H-USY was highly aromatic gasoline, while the product from HC was half-isoparaffinic/olefinic kerosene. Although more than 50 wt% of the products from HT/CC on the USY catalyst was liquefied petroleum gas due to overcracking, the product from HT/CC on the MFI catalyst was high-octane-number gasoline. Delightfully, the product from HT/HC was kerosene and its average number was 11, with more than 80 wt% being isoparaffinic. As a result, it was demonstrated that hydrotreating may convert isoprenoid oil from microalgae over nanoporous hybrid catalysts into a variety of products.

Potential displacement of petroleum imports by solar energy technologies

The United States currently imports close to half of its petroleum requirements. This report delineates the economic, social, and political costs of such a foreign oil dependency. These costs are often intangible, but combined they clearly constitute a greater price for imported petroleum than the strictly economic cost. If we can assume that imported oil imposes significant socioeconomic costs upon the American economy and society, one way to reduce these costs is to develop alternative, domestic energy sources - such as solar energy technologies - which can displace foreign petroleum. The second half of this report estimates that by the year 2000, solar energy technologies can displace 3.6 quads of petroleum. This figure includes solar energy applications in utilities, industrial and agricultural process heat, and transportation. The estimate can be treated as a lower bound; if the United States were to achieve the proposed goal of 20 quads by 2000, the amount of displaced oil probably would be greater. Although all the displaced oil would not be imported, the reduction in imported petroleum would relieve many of the conditions that increase the present cost of foreign oil to the American consumer.

Detecting Liquefied Petroleum Gas (LPG) at Room Temperature Using ZnSnO3/ZnO Nanowire Piezo-Nanogenerator as Self-Powered Gas Sensor.

High sensitivity, selectivity, and reliability have been achieved from ZnSnO3/ZnO nanowire (NW) piezo-nanogenerator (NG) as self-powered gas sensor (SPGS) for detecting liquefied petroleum gas (LPG) at room temperature (RT). After being exposed to 8000 ppm LPG, the output piezo-voltage of ZnSnO3/ZnO NW SPGS under compressive deformation is 0.089 V, much smaller than that in air ambience (0.533 V). The sensitivity of the SPGS against 8000 ppm LPG is up to 83.23, and the low limit of detection is 600 ppm. The SPGS has lower sensitivity against H2S, H2, ethanol, methanol and saturated water vapor than LPG, indicating good selectivity for detecting LPG. After two months, the decline of the sensing performance is less than 6%. Such piezo-LPG sensing at RT can be ascribed to the new piezo-surface coupling effect of ZnSnO3/ZnO nanocomposites. The practical application of the device driven by human motion has also been simply demonstrated. This work provides a novel approach to fabricate RT-LPG sensors and promotes the development of self-powered sensing system.

The Chinese government began to prepare for the establishment of strategic petroleum reserve in March 2004. Therefore, answering the question of what level of strategic petroleum reserve would be suitable for China's future economic development becomes essential. Using a decision tree model based on a cost function, this paper quantifies China's optimal strategic petroleum reserve for the period 2005-2020. This approach provides a methodology reference for further quantified discussion on China's SPR. Our results show that: for economic development and security of the energy supply, the strategic petroleum reserve should be the equivalent of 30-60 days of net oil import for an optimal solution, when the oil price is $ 50/bbl; with a reserve of an equivalent of 60-90 days of net oil import to have an optimal solution when oil price is $20-35/bbl.

Hydrocarbons dating by Re-Os method: experimental study of the Re-Os couple geochemical behaviour in oils during the evolution of a petroleum system

International Nuclear Information System (INIS)

Mahdaoui, Fatima

2013-01-01

The Re-Os radiogenic system is well adapted to the dating of oils and bitumen. However the meaning of the obtained age is ambiguous. This is mainly due to gaps in our knowledge of the geochemical behavior and the speciation of Re and Os in oils. Specifically, use of the Re-Os geo-chronometer requires an understanding of how Re-Os behavior can lead to the fulfillment of the conditions necessary for the development of an isochron. These conditions are: i) the isotopic homogenization of oils at the scale of a petroleum field ii) the fractionation of Re from Os so as to obtain samples with various Re/Os ratios iii) the closure of the system during the period of radiogenic ingrowth of the daughter isotope, that is, from the time of the event of interest to the present day. Experimental investigation of the organic geochemical behavior of Re and Os in oils under various conditions, designed as analogs of the different stages of petroleum generation and evolution, were performed in order to evaluate the use of the Re-Os system as a geo-chronometer in the context of a direct use on petroleum. The possibility of Re-Os fractionation resulting from asphaltene loss during oil evolution was investigated by sequential asphaltene precipitation in the laboratory. This study determined that Re and Os are mainly located in the most polar asphaltene fractions, that is, in the first to precipitate. This study also demonstrated that Re/Os ratios are not disturbed by asphaltene loss during the evolution of oils, unless this loss is unrealistically large. Thus asphaltene precipitation during migration and emplacement is not responsible for the Re/Os fractionation required for the use of the geo-chronometer. The possibility of metal transfer from formation waters to petroleum was studied by performing contact experiments between oils and aqueous solutions of Re and Os of various concentrations over a wide range of temperatures and for varying periods of time. This study demonstrated a

The oil refining industry in China has faced rapid growth in oil imports of increasingly sour grades of crude with which to satisfy growing domestic demand for a slate of lighter and cleaner finished products sold at subsidized prices. At the same time, the world petroleum refining industry has been moving from one that serves primarily local and regional markets to one that serves global markets for finished products, as world refining capacity utilization has increased. Globally, refined product markets are likely to experience continued globalization until refining investments significantly expand capacity in key demand regions. We survey the oil refining industry in China in the context of the world market for heterogeneous crude oils and growing world trade in refined petroleum products. (author)

Exports of petroleum products, 1988

International Nuclear Information System (INIS)

1989-04-01

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 m 3 /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

The role of the Arctic in future global petroleum supply

Energy Technology Data Exchange (ETDEWEB)

Lindholt, Lars; Glomsroed, Solveig

2011-07-01

The Arctic has a substantial share of global petroleum resources, but at higher costs than in most other petroleum provinces. Arctic states and petroleum companies are carefully considering the potential for future extraction in the Arctic. This paper studies the oil and gas supply from 6 arctic regions during 2010-2050 along with global economic growth and different assumptions regarding petroleum prices and resource endowments. Supply is calculated based on a global model of oil and gas markets. The data on undiscovered resources for the Arctic is based on the estimates by USGS. Sensitivity studies are carried out for two alternative price scenarios and for a 50 per cent reduction of arctic undiscovered resources compared with the USGS 2008 resource estimate. Although a major part of the undiscovered arctic petroleum resources is natural gas, our results show that the relative importance of the Arctic as a world gas supplier will decline, while its importance as a global oil producer may be maintained. We also show that less than full access to undiscovered oil resources will have minor effect on total arctic oil production and a marginal effect on arctic gas extraction. The reason is that Arctic Russia is an important petroleum producer with a sufficiently large stock of already discovered resources to support their petroleum production before 2050. (Author)

Real-time petroleum spill detection system

International Nuclear Information System (INIS)

Dakin, D.T.

2001-01-01

A real-time autonomous oil and fuel spill detection system has been developed to rapidly detect of a wide range of petroleum products floating on, or suspended in water. The system consists of an array of spill detection buoys distributed within the area to be monitored. The buoys are composed of a float and a multispectral fluorometer, which looks up through the top 5 cm of water to detect floating and suspended petroleum products. The buoys communicate to a base station computer that controls the sampling of the buoys and analyses the data from each buoy to determine if a spill has occurred. If statistically significant background petroleum levels are detected, the system raises an oil spill alarm. The system is useful because early detection of a marine oil spill allows for faster containment, thereby minimizing the contaminated area and reducing cleanup costs. This paper also provided test results for biofouling, various petroleum product detection, water turbidity and wave tolerance. The technology has been successfully demonstrated. The UV light source keeps the optic window free from biofouling, and the electronics are fully submerged so there is no risk that the unit could ignite the vapours of a potential oil spill. The system can also tolerate moderately turbid waters and can therefore be used in many rivers, harbours, water intakes and sumps. The system can detect petroleum products with an average thickness of less than 3 micrometers floating on the water surface. 3 refs., 15 figs

The total imports of oil and gas field equipment are estimated to increase to US$280.4 million in 1992, and the most important foreign suppliers are led by the USA, which has a 72% share. Canadian exports of oil and gas field equipment have remained fairly stable during the last few years at $2.4-2.7 million. In general, prospects for Canadian suppliers to the Mexican market are best in the area of technologically sophisticated equipment. An end-user profile of PEMEX is presented, noting that it is the largest enterprise in Latin America and had $14.2 billion in sales in 1989. Equipment imported by PEMEX includes seamless steel pipe, drilling tools, gate and control valves, electric motors, processing and control equipment, steam and gas turbines, and telecommunications equipment. PEMEX activities in 1989 are reviewed, including those in the petrochemical sector, and projected activities are described. Major efforts planned by PEMEX include expansion of petrochemical production. Access to the Mexican market is discussed in terms of PEMEX purchasing policy, payment system, import requirements, the need for using a supplier agent, and use of the metric system and other standards. 6 figs., 2 tabs

Field portable petroleum analysis for validation of the site characterization and analysis penetrometer system petroleum, oil and lubricant sensor

1995-01-01

A petroleum, oil and lubricant (POL) sensor for the Site Characterization and Analysis Penetrometer System (SCAPS) has been developed by the Tri-Services (e.g. Army, Navy and Air Force) to characterize the distribution of POL contaminants on military sites. The sensor is based on the detection of POL contaminants using a laser induced fluorescence (LIF) spectrometer. The SCAPS POL sensor has been shown to be a valuable tool for the rapid screening of POL contamination in the subsurface. However, many factors can affect the LIF response of a particular fuel at a particular site. These include fuel type, age of spill (e.g. weathering) and soil type. The LIF sensor also detects fluorescence from any naturally occurring fluorophores, including humic substances and fluorescent minerals. These factors lead to the development of an independent procedure for the verification of the POL sensor response. This paper describes a field portable total recoverable petroleum hydrocarbon (TRPH) method based on EPA Method 418.1 and its application to on site validation of the SCAPS POL sensor response at a number of contaminated sites

Profiles of Reservoir Properties of Oil-Bearing Plays for Selected Petroleum Provinces in the United States

Science.gov (United States)

Freeman, P.A.; Attanasi, E.D.

2015-11-05

Profiles of reservoir properties of oil-bearing plays for selected petroleum provinces in the United States were developed to characterize the database to be used for a potential assessment by the U.S. Geological Survey (USGS) of oil that would be technically recoverable by the application of enhanced oil recovery methods using injection of carbon dioxide (CO2-EOR). The USGS assessment methodology may require reservoir-level data for the purposes of screening conventional oil reservoirs and projecting CO2-EOR performance in terms of the incremental recoverable oil. The information used in this report is based on reservoir properties from the “Significant Oil and Gas Fields of the United States Database” prepared by Nehring Associates, Inc. (2012). As described by Nehring Associates, Inc., the database “covers all producing provinces (basins) in the United States except the Appalachian Basin and the Cincinnati Arch.”

Shell petroleum handbook. [Glossary included

Energy Technology Data Exchange (ETDEWEB)

1986-01-01

The present edition has been completely updated and revised, reflecting the very great changes which have come about in the oil industry over the last 18 years, since the last edition appeared. The expressed aim of the Handbook is to combine explanations of the processes of today's petroleum industry, from crude oil exploration to product end-use, with some historical background and explanation of the economic context in which the oil, gas and petrochemical industries operate. It is therefore intended as a technical reference manual, although it will be of interest both to specialists in search of information outside their expertise and to the more general reader. Chapter 3, entitled Exploration and Production, is concerned with structural geology, exploration methods and theory, and reservoir engineering, although the economic and financial aspects of drilling, project management and communication logistics are also considered. Other chapters are devoted to the distribution, consumption and end use of natural gas and NGL, the chemistry of petroleum, the manufacture of oil products, marketing, supply and trading, petrochemicals, synfuels, R and D, environmental conservation, and introduction to the world petroleum industry, and a review of oil and gas in the centrally planned economies, although only the Soviet Union is considered in any detail.

The role of the Arctic in future global petroleum supply

The Arctic has a substantial share of global petroleum resources, but at higher costs than in most other petroleum provinces. Arctic states and petroleum companies are carefully considering the potential for future extraction in the Arctic. This paper studies the oil and gas supply from 6 arctic regions during 2010-2050 along with global economic growth and different assumptions regarding petroleum prices and resource endowments. Supply is calculated based on a global model of oil and gas mar...

Interest grows in African oil and gas opportunities

Energy Technology Data Exchange (ETDEWEB)

Knott, D.

1997-05-12

As African countries continue a slow drift towards democratic government and market economics, the continent is increasingly attractive to international oil and gas companies. Though Africa remains politically diverse, and its volatile politics remains a major barrier to petroleum companies, a number of recent developments reflect its growing significance for the industry. Among recent projects and events reflecting changes in Africa: oil and gas exporter Algeria has invited foreign oil companies to help develop major gas discoveries, with a view to boosting exports to Europe; oil and gas producer Egypt invited foreign companies to explore in the Nile Delta region, and the result appears to be a flowering world scale gas play; west African offshore exploration has entered deep water and new areas, and a number of major projects are expected in years to come; Nigeria`s reputation as a difficult place to operate has been justified by recent political and civil events, but a long-planned liquefied natural gas (LNG) export plant is being built there; South Africa, which has returned to the international scene after years of trade isolation because of apartheid, is emerging as a potential driver for energy industry schemes throughout the continent. Activities are discussed.

Environmental pollution by petroleum

Energy Technology Data Exchange (ETDEWEB)

Murata, T

1974-06-01

Pollution causes, cases, and remedies at various stages of petroleum production and usage are reviewed. Petroleum extraction (off-shore drilling and Arctic drilling) can be accompanied by mishaps. In 1971, IMCO (an international safety committee) proposed the partitioning of oil tanker holds into smaller compartments to minimize spillage in case of disaster. Although the solubility of oil in waste water from refineries is reckoned by ppM, the total amount dissolved is not negligible. Petroleum storage and transport on land is complicated by problems of safety in terms of population density as well as by pollution problems. Petroleum end-products such as plastic trash and automobile exhausts contribute to pollution. The role of aldehydes and peroxides in photochemical smog formation must be investigated further. Proper treatment of pollution at each specific point of occurrence, rather than at the end of a production line is recommended. Pollutant concentration for treatment, rather than pollutant dilution for dispersal, should be considered. Technology for pollution abatement is available, but not always economically feasible.

Co-processing of standard gas oil and biocrude oil to hydrocarbon fuels

International Nuclear Information System (INIS)

Agblevor, Foster A.; Mante, O.; McClung, R.; Oyama, S.T.

2012-01-01

The major obstacle in thermochemical biomass conversion to hydrocarbon fuels using pyrolysis has been the high oxygen content and the poor stability of the product oils, which cause them to solidify during secondary processing. We have developed a fractional catalytic pyrolysis process to convert biomass feedstocks into a product termed “biocrude oils” (stable biomass pyrolysis oils) which are distinct from unstable conventional pyrolysis oils. The biocrude oils are stable, low viscosity liquids that are storable at ambient conditions without any significant increases in viscosity; distillable at both atmospheric pressure and under vacuum without char or solid formation. About 15 wt% biocrude oils containing 20–25% oxygen were blended with 85 wt% standard gas oil and co-cracked in an Advanced Catalyst Evaluation (ACE™) unit using fluid catalytic cracking (FCC) catalysts to produce hydrocarbon fuels that contain negligible amount of oxygen. For the same conversion of 70% for both the standard gas oil and the biocrude oil/gas oil blends, the product gasoline yield was 44 wt%, light cycle oil (LCO) 17 wt%, heavy cycle oil (HCO) 13 wt%, and liquefied petroleum gas (LPG) 16 wt%. However, the coke yield for the standard gas oil was 7.06 wt% compared to 6.64–6.81 wt% for the blends. There appeared to be hydrogen transfer from the cracking of the standard gas oil to the biocrude oil which subsequently eliminated the oxygen in the fuel without external hydrogen addition. We have demonstrated for the first time that biomass pyrolysis oils can be successfully converted into hydrocarbons without hydrogenation pretreatment. -- Highlights: ► The co-processed product had less than 1% oxygen content and contained biocarbons determined by 14 C analysis. ► The co-processing did not affect the yields of gasoline, LCO, and HCO. ► First demonstration of direct conversion of pyrolysis oils into drop-in hydrocarbon fuels.

Petroleum supply monthly, August 1994

Energy Technology Data Exchange (ETDEWEB)

1994-08-26

Data presented in the Petroleum Supply Monthly (PSM) describe the supply and disposition of petroleum products in the United States and major US geographic regions. The data series describe production, imports and exports, inter-Petroleum Administration for Defense (PAD) District movements, and inventories by the primary suppliers of petroleum products in the United States (50 States and the District of Columbia). The reporting universe includes those petroleum sectors in primary supply. Included are: petroleum refiners, motor gasoline blenders, operators of natural gas processing plants and fractionators, inter-PAD transporters, importers, and major inventory holders of petroleum products and crude oil. When aggregated, the data reported by these sectors approximately represent the consumption of petroleum products in the United States. Data presented in the PSM are divided into two sections: Summary Statistics and Detailed Statistics.

Canadian petroleum industry

Energy Technology Data Exchange (ETDEWEB)

Dagher, J.H.

1969-12-01

This study covers the following Canadian petroleum industry categories: (1) a brief history; (2) the demand for Alberta crude; (3) U.S. oil policies; (4) overseas exploration; (5) the national oil policy; (6) the Montreal pipeline and its targets; (7) a continental oil policy; and (8) the impact of Arctic reserves. It is noted that large potential benefits will improve from the Manhattan navigating the Northwest Passage. Without prejudging the analysis now applied to the information gathered on this voyage, the Manhattan has greatly contributed to the solution of the problem of access to the Arctic islands. The picture for natural gas is less fraught with uncertainties. Unlike oil, where domestic and international considerations may weigh in U.S. policy decision, Canadian natural gas is likely to be allowed to enjoy its full economic potential in bridging the foreseeable U.S. supply gap and, inasmuch as this potential is ultimately tied with that for crude oil markets, the anticipated U.S. needs for Canadian natural gas may be expected to enhance U.S. interest in the overall well-being of the Canadian petroleum industry.

Full Text Available The growing global demand for sustainable technologies that improves the efficiency of petrochemical processes in the oil industry has driven advances in petroleum biotechnology in recent years. Petroleum industry uses substantial amounts of petrochemical-based synthetic surfactants in its activities as mobilizing agents to increase the availability or recovery of hydrocarbons as well as many other applications related to extraction, treatment, cleaning and transportation. However, biosurfactants have several potential applications for use across the oil processing chain and in the formulations of petrochemical products such as emulsifying/demulsifying agents, anticorrosive, biocides for sulphate-reducing bacteria, fuel formulation, extraction of bitumen from tar sands and many other innovative applications. Due to their versatility and proven efficiency, biosurfactants are often presented as valuable versatile tools that can transform and modernise petroleum biotechnology in an attempt to provide a true picture of state of the art and directions or use in the oil industry. We believe that biosurfactants are going to have a significant role in many future applications in the oil industries and in this review therefore, we highlight recent important relevant applications, patents disclosures and potential future applications for biosurfactants in petroleum and related industries.

2010-02-01

There have been few cases of cold burn related to the exposure of liquid petroleum gas (LPG). We present the case of a young woman exposed to LPG while refueling her car who sustained partial thickness burns to the dorsum of her hand. Contact with LPG leaking from a pressurized system causes tissue damage because of cold injury. Immediate management of LPG is extrapolated from the management of frostbite. The increasing use of LPG mandates an awareness of prevention strategies and management principles in the setting of adverse events.

Comparative dermal carcinogenesis of shale and petroleum-derived distillates.

Clark, C R; Walter, M K; Ferguson, P W; Katchen, M

1988-03-01

Ten test materials derived from petroleum or hydrotreated shale oils were applied 3 times/week for up to 105 weeks to the shaved skin of 25 male and 25 female C3H/HeN mice per group. Mineral oil and benzo(a) pyrene (0.15%) were control materials. Clinical observations were recorded during the study. At death, histopathologic examination was conducted on skin, internal organs and any gross lesions. Exposures to some materials were ended midway in the study due to severe irritation. Chronic toxicity of all materials was limited to inflammatory and degenerative skin changes. Significant increases over control incidence of skin tumors (squamous cell carcinoma and fibrosarcoma) occurred with both petroleum and shale-derived naphtha (21%, 50%), Jet A (26%, 28%), JP-4 (26%, 50%), and crude oils (84%, 54%). Severely hydrotreated shale oil and petroleum and shale-derived diesel distillates were not considered tumorigenic. Results indicate that toxicity of comparable petroleum and shale-derived fractions was qualitatively similar and confirm earlier findings that hydrotreating reduces or eliminates carcinogenicity of raw shale oil.

Petroleum exclusion under CERCLA: A defense to liability

International Nuclear Information System (INIS)

Landreth, L.W.

1991-01-01

When CERCLA was originally passed in 1980, the petroleum industry lobbied successfully to exclude the term open-quotes petroleumclose quotes from the definition of a CERCLA section 101 (14) hazardous substance. Under CERCLA section 101 (33), petroleum is also excluded from the definition of a open-quotes pollutant or contaminant.close quotes Exclusion from the designation as a defined hazardous substance has provided a defense to liability under CERCLA section 107 when the release of petroleum occurs. The scope of the petroleum exclusion under CERCLA has been a critical and recurring issue arising in the context of Superfund response activities. Specifically, oil that is contaminated by hazardous substances during the refining process is considered open-quotes petroleumclose quotes under CERCLA and thus excluded from CERCLA response authority and liability unless specifically listed under RCRA or some other statute. The U.S. EPAs position is that contaminants present in used oil, or any other petroleum substance, do not fall within the petroleum exclusion. open-quotes Contaminants,close quotes as discussed here, are substances not normally found in refined petroleum fractions or present at levels which exceed those normally found in such fractions. If these contaminants are CERCLA hazardous substances, they are subject to CERCLA response authority and liability. This paper discusses the parameters of the CERCLA open-quotes Petroleum Exclusion.close quotes It briefly examines selected state laws, RCRA, the Clean Water Act (CWA) and the Safe Drinking Water Act (SDWA) for treatment of petroleum and petroleum products. And, finally, this paper discusses new legislation regarding oil pollution liability and compensation
