Time-weighted average (TWA) intensity of exposure of workers to benzene vapor during a shift was monitored by diffusive sampling technique in a Japanese petroleum refinery. The subjects monitored (83 in total) included refinery operators, laboratory personnel and tanker-loading workers. The results showed that the time-weighted average exposures are well below 1 ppm in most cases. The highest exposure was recorded in 1 case involved in bulk loading of tanker ships, in which exposure of over 1 ppm might take place depending on operational conditions. The observation was generally in agreement with levels previously reported.

This report summarizes the accomplishments toward project goals during the no cost extension period of the third year of the project to assess the properties and performance of coal based products. These products are in the gasoline, diesel and fuel oil range and result from coal based jet fuel production from an Air Force funded program. Specific areas of progress include generation of coal based material that has been fractionated into the desired refinery cuts for a third round of testing, the use of a research gasoline engine to test coal-based gasoline, and modification of diesel engines for use in evaluating diesel produced in the project. At the pilot scale, the hydrotreating process was modified to separate the heavy components from the LCO and RCO fractions before hydrotreating in order to improve the performance of the catalysts in further processing. Hydrotreating and hydrogenation of the product has been completed, and due to removal of material before processing, yield of the jet fuel fraction has decreased relative to an increase in the gasoline fraction. Characterization of the gasoline fuel indicates a dominance of single ring alkylcycloalkanes that have a low octane rating; however, blends containing these compounds do not have a negative effect upon gasoline when blended in refinery gasoline streams. Characterization of the diesel fuel indicates a dominance of 3-ring aromatics that have a low cetane value; however, these compounds do not have a negative effect upon diesel when blended in refinery diesel streams. Both gasoline and diesel continue to be tested for combustion performance. The desulfurization of sulfur containing components of coal and petroleum is being studied so that effective conversion of blended coal and petroleum streams can be efficiently converted to useful refinery products. Activated carbons have proven useful to remove the heavy sulfur components, and unsupported Ni/Mo and Ni/Co catalysts have been very effective for

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.

Analysis and control of odors from petroleum refineries

O'Brien, M.A.; Duffee, R.A.; Ostojic, N.

1992-01-01

This paper presents a proven approach used to effectively solve odor problems associated with atmospheric emissions from petroleum refineries. A systematic evaluation is first conducted to identify all emissions with the potential for off-site odor impacts. Sampling is then conducted and dynamic dilution olfactometry is used to quantify the odor emission rates of each source. Community odor surveys are performed simultaneously with the source sampling to quantitatively document the downwind odor impacts. Atmospheric dispersion modeling specifically designed for odor is then used to predict instantaneous odor occurrences at various receptor sites under meteorological conditions not actually encountered during the field study. The findings make it possible to rank sources by their odor emission rates and potential for odor impacts in the community. It is then possible to determine how much odor reduction is required to bring the present odor impacts of the individual sources to an acceptable level under worst-case meteorological conditions. Once the degree of control required is determined, control alternatives are selected and evaluated. Case histories have been selected to illustrate the application of this approach at petroleum refineries. They provide descriptions of odor assessment and abatement studies conducted specifically for refinery effluent treatment plant sources as well as process unit emission sources. The sources identified as needing control and the odor abatement measures taken are discussed

In our work, a new process, catalytic vacuum distillation (CVD) was utilized for purification of petroleum refinery wastewater that was characteristic of high chemical oxygen demand (COD) and salinity. Moreover, various common promoters, like FeCl(3), kaolin, H(2)SO(4) and NaOH were investigated to improve the purification efficiency of CVD. Here, the purification efficiency was estimated by COD testing, electrolytic conductivity, UV-vis spectrum, gas chromatography-mass spectrometry (GC-MS) and pH value. The results showed that NaOH promoted CVD displayed higher efficiency in purification of refinery wastewater than other systems, where the pellucid effluents with low salinity and high COD removal efficiency (99%) were obtained after treatment, and the corresponding pH values of effluents varied from 7 to 9. Furthermore, environment estimation was also tested and the results showed that the effluent had no influence on plant growth. Thus, based on satisfied removal efficiency of COD and salinity achieved simultaneously, NaOH promoted CVD process is an effective approach to purify petroleum refinery wastewater.

Health implications of petroleum refinery air emissions: Part I main report : Final : Executive summary

International Nuclear Information System (INIS)

2003-03-01

This report provides a review of recent public health risk assessments performed in the field of petroleum refineries, and epidemiological or community health studies of populations residing close to petroleum refineries. The objective was to identify and access information concerning possible health impacts specific to this industry. The small number of studies performed on the topic as well as shortcomings in study design, concomitant exposure to other industrial sources and somewhat inconsistent findings make the data difficult to interpret. Potential concerns include short-term respiratory effects from exposure to sulphur dioxide and other substances, and cancer risks from benzene and other substances. There was very limited support for these findings in epidemiology studies of populations in the vicinity of petroleum refineries. This review provides additional support concerning cardiac and respiratory effects of air pollution including particulate matter (PM) and ground level ozone

International Nuclear Information System (INIS)

Torres Contreras, Jose Francisco

2012-01-01

The fuels waste gases that are burned in a flare stack were proposed as an alternative for its utilization. The current operation of the flare stack system of a petroleum refinery was analyzed. The historical information of the equipment and original design of the same was used. From the calculations that were performed, it is expected that the delivered heat for the flare gases approaching to 65 MJ/M 3 , so it would be an effective fuel for be used in furnaces and boilers. A new flare stack system and a system for recovery of the waste gases of process is proposed. The new flare stack system must have a liquid separator of 2,3 meters of diameter, a length of 6,4 meters and a capacity of 26,1 cubic meters. The velocity of the gas to the exit of the separator has been of 80,7 m/s. The liquid hydrocarbon flow that has exited the separator has been of 71 m 3 /h, with a speed of 0,91 m/s and a pump of 2,75 HP is required. The liquid seal of flare stack systems must have a minimum height of 1,05 m. The gas recovery system to burn in the flare stack should be located between the liquid separator and liquid seal of the flare stack systems. For an average consumption of 150 m 3 /h of fuel gas for furnaces and boilers, the gas recovery system must have with a compressor of 4,75 HP, a liquid separator of 50 m 3 and a pump of 2,50 HP. The gas recovery system has had with an absorber of 7 plates for washing of the stream acid gas with MEA, at 40 degrees celsius and an pressure of operating of 67 kPa, and a flow of 55,88 kg/h at amine solution. The flare gas flow has been recommended to be analyzed chemically, as well as the measurement of the flow of gas streams plant consumption and gases flare. A technical-economic feasibility study of the process should be realized. (author) [es

commercial fuels ({approx}60 ON for coal-based gasoline and {approx}20 CN for coal-based diesel fuel). Therefore, the allowable range of blending levels was studied where the blend would achieve acceptable performance. However, in both cases of the coal-based fuels, their ignition characteristics may make them ideal fuels for advanced combustion strategies where lower ON and CN are desirable. Task 3 was designed to develop new approaches for producing ultra clean fuels and value-added chemicals from refinery streams involving coal as a part of the feedstock. It consisted of the following three parts: (1) desulfurization and denitrogenation which involves both new adsorption approach for selective removal of nitrogen and sulfur and new catalysts for more effective hydrotreating and the combination of adsorption denitrogenation with hydrodesulfurization; (2) saturation of two-ring aromatics that included new design of sulfur resistant noble-metal catalysts for hydrogenation of naphthalene and tetralin in middle distillate fuels, and (3) value-added chemicals from naphthalene and biphenyl, which aimed at developing value-added organic chemicals from refinery streams such as 2,6-dimethylnaphthalene and 4,4{prime}-dimethylbiphenyl as precursors to advanced polymer materials. Major advances were achieved in this project in designing the catalysts and sorbent materials, and in developing fundamental understanding. The objective of Task 4 was to evaluate the effect of introducing coal into an existing petroleum refinery on the fuel oil product, specifically trace element emissions. Activities performed to accomplish this objective included analyzing two petroleum-based commercial heavy fuel oils (i.e., No. 6 fuel oils) as baseline fuels and three co-processed fuel oils, characterizing the atomization performance of a No. 6 fuel oil, measuring the combustion performance and emissions of the five fuels, specifically major, minor, and trace elements when fired in a watertube boiler

Crude oil and its refining products are the most frequent contaminants, found in the environment due to spills. The aim of this work was the identification of spill source(s) in the subsurface of a petroleum refinery. Free phase samples were analyzed with gas chromatography and the analytical results were interpreted using Principal Component Analysis (PCA) method. The chemical analysis of groundwater samples from the refinery subsurface was also employed to obtain a comprehensive picture of the spill distribution and origin. (authors)

Southern Research (SR) in cooperation with U.S. Department of Energy (DOE), Bioenergy Technology Office (BETO), investigated a biomass liquefaction process for economic production of stabilized refinery-ready bio-oil. The project was awarded by DOE under a Funding Opportunity Announcement (DE-FOA-0000686) for Bio-oil Stabilization and Commoditization that intended to evaluate the feasibility of using bio-oil as a potential feedstock in an existing petroleum refinery. SR investigated Topic Area 1 of the FOA at Technology Readiness Level 2-3 to develop thermochemical liquefaction technologies for producing a bio-oil feedstock from high-impact biomass that can be utilized within a petroleum refinery. Bio-oil obtained from fast pyrolysis of biomass is a green intermediate that can be further upgraded into a biofuel for blending in a petroleum refinery using a hydro-deoxygenation (HDO) route. Co-processing pyrolysis bio-oil in a petroleum refinery is an attractive approach to leverage the refinery’s existing capital. However, the petroleum industry is reluctant to accept pyrolysis bio-oil because of a lack of a standard definition for an acceptable bio-oil feedstock in existing refinery processes. Also per BETO’s multiyear program plan, fast pyrolysis-based bio-fuel is presently not cost competitive with petroleum-based transportation fuels. SR aims to develop and demonstrate a cost-effective low-severity thermal liquefaction and hydrodeoxygenation (HDO) process to convert woody biomass to stabilized bio-oils that can be directly blended with hydrotreater input streams in a petroleum refinery for production of gasoline and/or diesel range hydrocarbons. The specific project objectives are to demonstrate the processes at laboratory scale, characterize the bio-oil product and develop a plan in partnership with a refinery company to move the technology towards commercialization.

A fuel quality processing study to provide a data base for an intelligent tradeoff between advanced turbine technology and liquid fuel quality, and also, to guide the development of specifications of future synthetic fuels anticipated for use in the time period 1985 to 2000 is given. Four technical performance tests are discussed: on-site pretreating, existing refineries to upgrade fuels, new refineries to upgrade fuels, and data evaluation. The base case refinery is a modern Midwest refinery processing 200,000 BPD of a 60/40 domestic/import petroleum crude mix. The synthetic crudes used for upgrading to marketable products and turbine fuel are shale oil and coal liquids. Of these syncrudes, 50,000 BPD are processed in the existing petroleum refinery, requiring additional process units and reducing petroleum feed, and in a new refinery designed for processing each syncrude to produce gasoline, distillate fuels, resid fuels, and turbine fuel, JPGs and coke. An extensive collection of synfuel properties and upgrading data was prepared for the application of a linear program model to investigate the most economical production slate meeting petroleum product specifications and turbine fuels of various quality grades. Technical and economic projections were developed for 36 scenarios, based on 4 different crude feeds to either modified existing or new refineries operated in 2 different modes to produce 7 differing grades of turbine fuels. A required product selling price of turbine fuel for each processing route was calculated. Procedures and projected economics were developed for on-site treatment of turbine fuel to meet limitations of impurities and emission of pollutants.

Ranking environmental liabilities at a petroleum refinery

International Nuclear Information System (INIS)

Lupo, M.

1995-01-01

A new computer model is available to allow the management of a petroleum refinery to prioritize environmental action and construct a holistic approach to remediation. A large refinery may have numerous solid waste management units regulated by the Resource Conservation and Recovery Act (RCRA), as well as process units that emit hazardous chemicals into the environment. These sources can impact several environmental media, potentially including the air, the soil, the groundwater, the unsaturated zone water, and surface water. The number of chemicals of concern may be large. The new model is able to rank the sources by considering the impact of each chemical in each medium from each source in terms of concentration, release rate, and a weighted index based on toxicity. In addition to environmental impact, the sources can be ranked in three other ways: (1) by cost to remediate, (2) by environmental risk reduction caused by the remediation in terms of the decreases in release rate, concentration, and weighted index, and (3) by cost-benefit, which is the environmental risk reduction for each source divided by the cost of the remedy. Ranking each unit in the refinery allows management to use its limited environmental resources in a pro-active strategic manner that produces long-term results, rather than in reactive, narrowly focused, costly, regulatory-driven campaigns that produce only short-term results

Petroleum product market outlook

International Nuclear Information System (INIS)

2005-09-01

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

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.

1996-01-01

The Canadian Petroleum Products Institute (CPPI) is an association of Canadian companies involved in the downstream sector of the petroleum industry which includes refining, distributing and marketing of petroleum products. CPPI's mandate includes: (1) establishing environmental policies, (2) establishing working relationships with governments to develop public policy, (3) developing guidelines for the safe handling of petroleum products, and (4) providing information about the petroleum industry to the public. Canada's 19 refineries processed an average of 1.5 million barrels of crude oil per day in 1996. Domestic sources of crude made up 61 per cent of crude oil processed in 1996. Total exports during the year amounted to 105 million barrels. Some of the issues that the CPPI focused on during 1996 included the controversy over the future of the octane enhancing fuel additive MMT, fuel quality standards for transportation fuels and reformulated fuels, gasoline pricing, air quality and workplace safety. CPPI members' participation in the Voluntary Challenge and Registry (VCR) program towards reducing greenhouse gas emissions was also discussed. The industry was also actively involved in seeking to improve its refinery wastewater discharges

Full Text Available Kautagi clay is a kaolin type deposit that is abundantly available in Niger State, Nigeria with potential for application in pollution control such as wastewater treatment. This study investigates the optimum conditions for modification of Kpautagi clay for application in refinery wastewater treatment. Sulphuric acid was used in the modification of the clay and the modification variables considered were acid concentration, activation time and temperature. To develop the optimum conditions for the modification variables, the sulphuric acid modified Kpautagi clay was applied in the treatment of refinery wastewater in column mode at a fixed flow rate and mass of adsorbent. The results obtained indicate that the optimum conditions for modification of Kpautagi clay for application in the treatment of petroleum refinery wastewater are: acid concentration of 4M; activation time of 120min and activation temperature of 100°C. Therefore, the optimum conditions developed in this study for modification of Kpautagi clay could be applied for improved performance in the treatment of petroleum refinery wastewater.

The Cement industry is a very energy intensive industry. Each ton of cement produced requires 60 to 130 kilograms of fuel oil or an equivalent fuelling amount also requires an average 110 kWh of electricity as well over 40% of total production cost is the energy requirements in the cement industry (i.2). Normally oil, gas or coal is fired in cement kilns as traditional fuels. However use of waste, both as alternative fuels and raw materials is now common practice in many cement companies. Many different types of wastes are burnt today in cement kilns like used tyres, rubber, paper waste, waste oils, waste wood, paper sludge, sewage, animal meal and animal remains (i,4). The choice of fuel for the purpose is normally based on price and availability considering different properties of the fuel as energy contents, ash contents, moisture and volatiles contents. Petcoke is not yet produced in any petroleum refinery in Pakistan but it is abundantly available in the market worldwide as it is obtained as a waste product during the refining processes. The purpose of the current research is to figure out the suitability of petroleum coke as a fuel for cement industry both on technical and economic basis. (author)

Rao, P. [Pennsylvania State Univ., University Park, PA (United States)

2000-07-01

The Petroleum Refinery Maximum Achievable Control Technology (MACT) II standards were recently announced by the United States Environmental Protection Agency. The standards are designed to control hazardous air pollutants (HAPs) from fluid catalytic cracking (FCC), catalytic reforming and sulfur recovery units. The major role of feed quality in determining emissions of heavy metals, sulfur oxides (SOx) and nitrous oxides from FCC vents were discussed. The impact of FCC feed quality on carbon dioxide emissions was also examined. Some potential loopholes in the SOx new source performance standard for FCCs were also identified. This paper also outlined regulatory issues that occur when pollutant emission rates vary with raw material or fuel quantity. When input qualities vary, the format of emission standards take on special meaning. In particular, proportional control standards perform poorly resulting in environmentally damaged inputs. Precautions should be taken in profit-induced moves to avoid lower quality inputs, particularly at this time for setting new directions for a cleaner environment. 22 refs., 2 tabs., 10 figs.

1991-04-01

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 1990 calendar year. Exports of the above petroleum products averaged 34,000 m 3 /d in 1990, up 12% from 1989 levels. The increase reflects increased output from the Come By Chance refinery in Newfoundland. Motor gasoline exports increased 35% to 10,500 m 3 /d, reflecting refinery upgrading in eastern Canada. Export prices were generally in line with spot product prices in the USA. Spot prices rose sharply following the Kuwait crisis in August 1990 but fell again in November. The spot price for jet fuel rose more dramatically in that period than for other products, reflecting increased military demand. In winter 1989/90 and during the Kuwait conflict, the export price of heating oil tended to track the USA spot price. Petroleum products imports in 1990 were 18,500 m 3 /d, compared to 21,900 m 3 /d in 1988. Imports were lower partially as a result of higher crude runs in Quebec and a Quebec refinery expansion. Imports of heavy fuel oil in eastern Canada continued to be strong in comparison to the mid-1980s. The top single exporter in 1990, as in 1989, was Newfoundland Processing, with a volume of 4,506,400 m 3 . 13 figs., 5 tabs

Workers handle catalysts extensively at petroleum refineries throughout the world each year; however, little information is available regarding the airborne concentrations and plausible exposures during this type of work. In this paper, we evaluated the airborne concentrations of 15 metals and total dust generated during solid catalyst loading and unloading operations at one of the largest petroleum refineries in the world using historical industrial hygiene samples collected between 1989 and 2006. The total dust and metals, which included aluminum, cadmium, chromium, cobalt, copper, iron, lead, manganese, molybdenum, nickel, platinum, silicon, silver, vanadium, and zinc, were evaluated in relation to the handling of four different types of solid catalysts associated with three major types of catalytic processes. Consideration was given to the known components of the solid catalysts and any metals that were likely deposited onto them during use. A total of 180 analytical results were included in this analysis, representing 13 personal and 54 area samples. Of the long-term personal samples, airborne concentrations of metals ranged from refinery and perhaps other modern refineries during the timeframe examined. Copyright © 2011 Elsevier GmbH.

Petroleum refinery workers' exposure to the carcinogens benzene and 1,3-butadiene has decreased during normal operations. However, certain occupational groups or events at the refineries still involve a risk of higher exposures. The aim of this study was to examine the personal exposure to benzene and 1,3-butadiene at refinery turnarounds and during work in the oil harbour. Personal exposure measurements of benzene and 1,3-butadiene were taken during work shifts, with a priori assumed higher benzene exposure, using PerkinElmer diffusive samplers filled with Carbopack X. Mean exposure levels were calculated, and repeated exposure measurements, when available, were assessed using mixed effect models. Group and individual compliance with the Swedish occupational exposure limit (OEL) was tested for the different exposure groups. Mean benzene exposure levels for refinery workers during the three measured turnarounds were 150, 610 and 960 µg/m 3 , and mean exposures for oil harbour workers and sewage tanker drivers were 310 and 360 µg/m 3 , respectively. Higher exposures were associated with handling benzene-rich products. Most occupational groups did not comply with the Swedish OEL for benzene nor did the individuals within the groups. The exposure to 1,3-butadiene was very low, between Work within the petroleum refinery industry, with potential exposure to open product streams containing higher fractions of benzene, pose a risk of personal benzene exposures exceeding the OEL. Refinery workers performing these work tasks frequently, such as contractors, sewage tanker drivers and oil harbour workers, need to be identified and protected.

The rise and fall of refineries

International Nuclear Information System (INIS)

Chretien, D.

2002-01-01

This paper described the rise and fall of refineries in Montreal. Well before Calgary, Montreal was the hub of activity for oil refineries because Montreal was the principle consuming market for petroleum products in Canada. The location was good, particularly since the soil was clay which helped prevent soil infiltration of petroleum. The first refinery in Montreal was constructed in 1916 by Esso, followed by Texaco in 1921 and Gulf in 1931. Initially oil was shipped by boat to the Port of Montreal from Saudi Arabia. Later, the petroleum came mostly from Venezuela. At the beginning of the 1980s many refineries were closed because they became obsolete and upgrading them would have been too costly. Only 3 refineries remain in Quebec, of which 2 are in Montreal. They are owned by Shell and PetroCanada. The third refinery in Quebec is in St-Romuald and is owned by UltraMar. One of the major contributing factors to the decline of the refining industry in Montreal was the decision in 1984 by former Prime Minister Trudeau to force Canadian provinces to purchase their petroleum from Alberta. This caused the petrochemical industry to locate in Sarnia in Ontario, leaving the Montreal refining centre to become obsolete. 3 figs

An estimation of cogeneration potential by using refinery residuals in Mexico

International Nuclear Information System (INIS)

Marin-Sanchez, J.E.; Rodriguez-Toral, M.A.

2007-01-01

Electric power generation in Mexico is mainly based on fossil fuels, specifically heavy fuel oil, although the use of natural gas combined cycles (NGCC) is becoming increasingly important. This is the main destination that has promoted growing imports of natural gas, currently accounting for about 20% of the total national annual consumption. Available crude oil is becoming heavier; thus refineries should be able to process it, and to handle greater quantities of refinery residuals. If all refinery residuals are used in cogeneration plants serving petroleum refineries, the high heat/power ratio of refinery needs, leads to the availability of appreciable quantities of electricity that can be exported to the public utility. Thus, in a global perspective, Mexican imports of natural gas may be reduced by cogeneration using refinery residuals. This is not the authors' idea; in fact, PEMEX, the national oil company, has been entitled by the Mexican congress to sell its power leftovers to The Federal Electricity Commission (CFE) in order to use cogeneration in the way described for the years to come. A systematic way of determining the cogeneration potential by using refinery residuals from Mexican refineries is presented here, taking into account residual quantities and composition, from a national perspective, considering expected scenarios for Maya crude content going to local refineries in the years to come. Among different available technologies for cogeneration using refinery residuals, it is believed that the integrated gasification combined cycle (IGCC) would be the best option. Thus, considering IGCC plants supplying heat and power to refineries where it is projected to have refinery residuals for cogeneration, the expected electric power that can be sent to the public utility is quantified, along with the natural gas imports mitigation that may be attained. This in turn would contribute to a necessary fuel diversification policy balancing energy, economy and

The worldwide trends in the crude oil supply indicate a continuous increase of the heavy crudes. The increase in the yield of distillation residues is complemented by an increase in their sulfur content. Additional distillates are produced by upgrading the residues. The upgrading step generates final residues, such as visbreaking tar, coke and asphalt which are produced by visbreaking, coking and de-asphalting, respectively. The final residues can be converted to usable products such as hydrogen, steam, electricity, ammonia and chemicals. For this purpose, gasification has emerged as the technology of choice because of its superior environmental performance when compared with the competing means for residue utilization. Also, refinery sludges can be co-gasified with the final residues and as such, be converted to usable products. If integrated with the petroleum refinery, gasification can diminish any environmental problems associated with residue and sludge disposal. The economic indicators of the refinery can improve as well. The trends in deregulation of the power market enable petroleum refineries to enter this lucrative market either alone or in a partnership with the utilities. The potential of co-production of chemicals and steam with electricity offers the flexibility to respond to market demands. Gasification technology is commercially proven. Among several types, entrained bed gasifiers are the gasifiers of choice. A number of commercial projects in Europe, Asia and United States use a gasifier employing either a slurry feeding system or a dry feeding system. (author)

Documentation of the petroleum market model (PMM). Appendix: Model developer's report

International Nuclear Information System (INIS)

1994-01-01

The Office of Integrated Analysis and Forecasting (OIAF) is required to provide complete model documentation to meet the EIA Model Acceptance Standards. The EIA Model Documentation: Petroleum Market Model of the National Energy Modeling System provides a complete description of the Petroleum Market Model's (PMM) methodology, and relation to other modules in the National Energy Modeling System (NEMS). This Model Developer's Report (MDR) serves as an appendix to the methodology documentation and provides an assessment of the sensitivity of PMM results to changes in input data. The MDR analysis for PMM is performed by varying several sets of input variables one-at-a-time and examining the effect on a set of selected output variables. The analysis is based on stand-alone, rather than integrated, National Energy Modeling System (NEMS) runs. This means that other NEMS modules are not responding to PMM outputs. The PMM models petroleum refining and marketing. The purpose of the PMM is to project petroleum product prices, refining activities, and movements of petroleum into the United States and among domestic regions. In addition, the PMM estimates capacity expansion and fuel consumption in, the refining industry. The PMM is also used to analyze a wide variety of petroleum-related issues and policies, in order to foster better understanding of the petroleum refining and marketing industry and the effects of certain policies and regulations. The PMM simulates the operation of petroleum refineries in the United States, including the supply and transportation of crude oil to refineries, the regional processing of these raw materials into petroleum products, and the distribution of petroleum products to meet regional demands. The essential outputs of this model are product prices, a petroleum supply/demand balance, demands for refinery fuel use, and capacity expansion

The petroleum refineries have shown high water's consuming that creates high costs and damages the hydric resources. However, the industrial sector, especially the petroleum industry, has been looking for alternatives that minimizing the impact caused by to use these natural resources. Currently, methodologies of controlling the pollution on the source have been appearing how a strong tendency and the reuse and/or recycle of wastewater can be emphasized. The optimization by mathematical programming, together with engineering know-how, is one of the great tendency in process integration technology developed. The present work presents one optimization mathematical model that objectifies to reduce the water's consuming and/or operational costs. The model is based in chemical species and mass conservation equation. This work presents the solution of one case found in literature that broach one petroleum refinery's network of water. This network is composed of six operations and three regenerative processes, and there are four keys contaminants. The water's consuming was minimized first and next the minimum cost in the minimum consume was broached. The results found were enough satisfactory and presented reductions up to 76% in the water consume and approximately 65% in the operational costs. (author)

Rationalization of imports, refineries and distribution of petroleum in Sub-Saharan Africa

International Nuclear Information System (INIS)

Mayorga Alba, E.

1993-01-01

This paper outlines policies to secure and reduce the cost of oil supplies in Sub-Saharan Africa (SSA), taking into account the existing forces at play: limited foreign exchange, competition for increasingly scarce funds, and the likely emergence of Africa as the fastest growing centre of energy demand over the coming decade. It identifies major inefficiencies in petroleum procurement, refining and distribution, and analyses the specific bottlenecks at each stage of the supply chain. Many of the diseconomies, estimated to yield savings of US$ 1.4 per year, are traced to an inefficient regulatory set-up in SSA countries, as well as unnecessary government interference in the downstream petroleum sector. In particular, price controls, small topping refineries, monopolistic agencies, government subsidies and opaque management structures prevent the working of efficient market mechanisms. The paper discusses the importance of policy reform, outlining what changes need to be implemented on the levels of institutional arrangements, closing of inefficient units, petroleum pricing and encouraging foreign investment in the sector.

1988-04-01

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 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

Groundwater contamination with benzene, toluene, ethylbenzene and xylene (BTEX) has been increasing, thus requiring an urgent development of methodologies that are able to remove or minimize the damages these compounds can cause to the environment. The biodegradation process using microorganisms has been regarded as an efficient technology to treat places contaminated with hydrocarbons, since they are able to biotransform and/or biodegrade target pollutants. To prove the efficiency of this process, besides chemical analysis, the use of biological assessments has been indicated. This work identified and selected BTEX-biodegrading microorganisms present in effluents from petroleum refinery, and evaluated the efficiency of microorganism biodegradation process for reducing genotoxic and mutagenic BTEX damage through two test-systems: Allium cepa and hepatoma tissue culture (HTC) cells. Five different non-biodegraded BTEX concentrations were evaluated in relation to biodegraded concentrations. The biodegradation process was performed in a BOD Trak Apparatus (HACH) for 20 days, using microorganisms pre-selected through enrichment. Although the biodegradation usually occurs by a consortium of different microorganisms, the consortium in this study was composed exclusively of five bacteria species and the bacteria Pseudomonas putida was held responsible for the BTEX biodegradation. The chemical analyses showed that BTEX was reduced in the biodegraded concentrations. The results obtained with genotoxicity assays, carried out with both A. cepa and HTC cells, showed that the biodegradation process was able to decrease the genotoxic damages of BTEX. By mutagenic tests, we observed a decrease in damage only to the A. cepa organism. Although no decrease in mutagenicity was observed for HTC cells, no increase of this effect after the biodegradation process was observed either. The application of pre-selected bacteria in biodegradation processes can represent a reliable and

Studies have shown that wastewater from refineries could induce vitellogenin (Vg) in juvenile rainbow trout. Vg is a biomarker of exposure to estrogenic chemicals. This study reassessed the estrogenic potency of the wastewater from an Ontario refinery and assessed the estrogenicity of wastewater from 3 petrochemical facilities. A 21 day static renewal test was conducted to test the effluents and in which a competitive binding ELISA detected induced Vg. Statistical testing for tank effects was performed in a replicated tank design and the St. Clair River water from upstream industrial facilities was used as a negative reference. The positive control treatment was waterborne 17β-estradiol. Wastewater from the petroleum refinery induced Vg in the treated fish, but wastewater from the petrochemical effluents did not induce detectable levels of Vg in treated trout. The information obtained through this study will be used to determine the potential for responses in feral fish

Analysis of standard and innovative methods for allocating upstream and refinery GHG emissions to oil products

Highlights: •Traditional and innovative methods for allocating emissions at refinery level are reviewed. •Added value has been introduced as a novel allocation method. •Hydrogen-based consistency test has been introduced to validate the allocation methods. •Consistent allocation methods assign negative refinery emissions to heavy products. -- Abstract: Alternative fuel policies need accurate and transparent methods to find the embedded carbon intensity of individual refinery products. This study investigates different ways of allocating greenhouse gases emissions deriving from refining and upstream crude oil supply. Allocation methods based on mass, energy content, economic value and, innovatively, added-value, are compared with the marginal refining emissions calculated by CONCAWE’s linear-programming model to the average EU refinery, which has been adopted as reference in EU legislation. Beside the most important transportation fuels (gasoline, diesel, kerosene/jet fuel and heavy fuel oil), the analysis extends to petroleum coke and refinery hydrogen. Moreover, novel criteria, based on the implications due to hydrogen usage by each fuel pathway, have been introduced to test the consistency of the analyzed approaches. It is found that only two economic-based allocation methods are consistent with the introduced criteria. These two methods also give negative refinery emissions for heavy products, which is coherent with the marginal emissions calculated through the CONCAWE refinery model. The recommended allocation methods are transparent and use only publicly available statistical data, so they may be useful not only for future EU legislation, but also in jurisdictions where a representative refinery model is not available.

Higher-octane gasoline can enable increases in an internal combustion engine’s energy efficiency and a vehicle’s fuel economy by allowing an increase in the engine compression ratio and/or by enabling downspeeding and downsizing. Producing high-octane fuel (HOF) with the current level of ethanol blending (E10) could increase the energy and greenhouse gas (GHG) emissions intensity of the fuel product from refinery operations. Alternatively, increasing the ethanol blending level in final gasoline products could be a promising solution to HOF production because of the high octane rating and potentially low blended Reid vapor pressure (RVP) of ethanol at 25% and higher of the ethanol blending level by volume. In our previous HOF well-to-wheels (WTW) report (the so-called phase I report of the HOF WTW analysis), we conducted WTW analysis of HOF with different ethanol blending levels (i.e., E10, E25, and E40) and a range of vehicle efficiency gains with detailed petroleum refinery linear programming (LP) modeling by Jacobs Consultancy and showed that the overall WTW GHG emission changes associated with HOFVs were dominated by the positive impact associated with vehicle efficiency gains and ethanol blending levels, while the refining operations to produce gasoline blendstock for oxygenate blending (BOB) for various HOF blend levels had a much smaller impact on WTW GHG emissions (Han et al. 2015). The scope of the previous phase I study, however, was limited to evaluating PADDs 2 and 3 operation changes with various HOF market share scenarios and ethanol blending levels. Also, the study used three typical configuration models of refineries (cracking, light coking, and heavy coking) in each PADD, which may not be representative of the aggregate response of all refineries in each PADD to various ethanol blending levels and HOF market scenarios. Lastly, the phase I study assumed no new refinery expansion in the existing refineries, which limited E10 HOF production to the

Dinitrogen-fixing activity (acetylene reduction and 15 N 2 fixation) was found in an oily sludge originating from a petroleum refinery. Two representative dinitrogen-fixing bacterial strains were isolated from this oily waste. Their nitrogenase activity was effective when they were cultivated on sterilized sludge or simple carbon substrates (organic acid salts, sugars). Using the classical methods, these strains could not be unambiguously related to other diazotrophic taxa. The landfarming process is widely used for oily sludge disposal; this study shows that oily sludges are more than a simple carbon input into the soil but that they must also be considered as real sources of dinitrogen-fixing and probably degradative microorganisms

In response to the RCRA land ban regulations and TC rule promulgated by the U.S. Federal Environmental Protection Agency (EPA) in 1988-1990, an Integrated Refinery Waste Management (IRWM) program has been developed to provide cost-effective solutions to petroleum industry customers. The goal of IRWM is to provide technology based remediation treatment services to manage sludges and wastewaters generated from the oil refining processes, soils contaminated with petroleum distillates and groundwater contaminated with fuels. Resource recovery, volume reduction and waste minimization are the primary choices to mitigate environmental problems. Oil recovery has been performed through phase separation (such as centrifugation and filtration) and heating of heavy oils. Volume reduction is achieved by dewatering systems such as centrifuges and filter presses, and low temperature thermal treatment. Waste minimization can be accomplished by bioremediation and resource recovery through a cement kiln. (Author).

Current efforts to monitor trace contaminants in treated oil refinery wastewaters increase the need to implement systematic, clear, and consistent procedures for reporting and presenting all monitoring data. The ability to interpret trace contaminant data which is to be collected by the governments of the U.S. and Canada for regulations development will rely on information about operating procedures and the efficiency of removal of conventional pollutants. An overview is provided of the main issues which must be addressed in managing and analyzing data from wastewater treatment facilities. The objectives of enviromental data management and analysis are discussed from the point of view of both the plant operator or owner and the regulatory authority. Based on the examination of the 1985 records of flow and phenol concentrations from seven Canadian petroleum refineries, recommendations are made for improving existing databases. In analyzing environmental data to transform raw data into information, exploratory data analysis techniques should be used by engineers or operators who do not have formal statistical training. These methods employ simple statistical summaries and graphical data displays. The paper concludes with a brief discussion about future trends in environmental data management and analysis. 15 refs., 5 figs., 2 tabs.

Highlights: ► A UASB was successfully used for treatment of petroleum refinery effluent. ► Response surface methodology was applied to design and analysis of experiments. ► System was modeled between efficient factors include HRT, influent COD and V up . ► UASB was able to remove about 76.3% influent COD at optimum conditions. - Abstract: An upflow anaerobic sludge blanket (UASB) bioreactor was successfully used for the treatment of petroleum refinery effluent. Before optimization, chemical oxygen demand (COD) removal was 81% at a constant organic loading rate (OLR) of 0.4 kg/m 3 d and a hydraulic retention time (HRT) of 48 h. The rate of biogas production was 559 mL/h at an HRT of 40 h and an influent COD of 1000 mg/L. Response surface methodology (RSM) was applied to predict the behaviors of influent COD, upflow velocity (V up ) and HRT in the bioreactor. RSM showed that the best models for COD removal and biogas production rate were the reduced quadratic and cubic models, respectively. The optimum region, identified based on two critical responses, was an influent COD of 630 mg/L, a V up of 0.27 m/h, and an HRT of 21.4 h. This resulted in a 76.3% COD removal efficiency and a 0.25 L biogas/L feed d biogas production rate.

Investigating an effective supply chain for a refinery in a regulated petroleum sector

Directory of Open Access Journals (Sweden)

Chris Adendorf

2012-12-01

Full Text Available Currently, refined petroleum products are manufactured by six refineries in South Africa. The supply of refined petroleum products is supplemented by imports of refined petroleum products. These refined petroleum products are transported by pipeline, rail, road, sea and a combination thereof to depots across the country. These products are then distributed directly to commercial customers through points of resale in the form of retail service stations. The challenge is that the storage facilities and distribution networks in South Africa are currently utilised to its full capacity. There is a need to expand current storage infrastructure or to erect new storage facilities to facilitate imports. Durban Port that currently handles 70% of the country’s crude oil and 40% of refined products is also utilised to its full capacity. The investigated problem pertains to the limited storage and transport capacity available for the distribution of petroleum products in the country. The interview protocol, which was based on the literature reviewed, was used for compiling the primary data for the case study. Selected findings revealed that the respondents perceived that storage capacity is the most significant constraint militating against adequate supply by the supply chain. The findings also indicated that the respondents were of the opinion that transport rates and routes (cost of logistics are the greatest contributor to the prices of products. As a result, there appears to be a major scope for improvement in terms of the usage of pipelines and rails for the movement of petroleum products.

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

Intrinsic biodegradation potential of bacteria from petroleum refinery waste was investigated through isolation of cultivable strains and their characterization. Pseudomonas and Bacillus spp. populated the normal cultivable taxa while prolonged enrichment with hydrocarbons and crude oil yielded hydrocarbonoclastic bacteria of genera Burkholderia, Enterobacter, Kocuria, Pandoraea, etc. Strains isolated through enrichment showed assemblages of superior metabolic properties: utilization of aliphatic (C6-C22) and polyaromatic compounds, anaerobic growth with multiple terminal electron acceptors and higher biosurfactant production. Biodegradation of dodecane was studied thoroughly by GC-MS along with detection of gene encoding alkane hydroxylase (alkB). Microcosms bioaugmented with Enterobacter, Pandoraea and Burkholderia strains showed efficient biodegradation (98% TPH removal) well fitted in first order kinetic model with low rate constants and decreased half-life. This study proves that catabolically efficient bacteria resides naturally in complex petroleum refinery wastes and those can be useful for bioaugmentation based bioremediation.

Intrinsic biodegradation ability of the indigenous microorganisms was enhanced significantly (>80% reduction in TPH by 90 days with nitrate amendment. Preferred utilization of both higher- (>C30 and middle- chain (C20-30 length hydrocarbons were evident from GC-MS analysis. Denaturing gradient gel electrophoresis (DGGE and community level physiological profiling (CLPP analyses indicated distinct shift in community’s composition and metabolic abilities following nitrogen (N amendment. High throughput deep sequencing of 16S rRNA gene showed that the native community was mainly composed of hydrocarbon degrading, syntrophic, methanogenic, nitrate/iron/sulfur reducing facultative anaerobic bacteria and archaebacteria, affiliated to γ- and δ-Proteobacteria and Euryarchaeota respectively. Genes for aerobic and anaerobic alkane metabolism (alkB and bssA, methanogenesis (mcrA, denitrification (nirS and narG and N2 fixation (nifH were detected.

Edokpolo, Benjamin; Yu, Qiming Jimmy; Connell, Des

2015-01-01

Health risk characterization of exposure to benzene in service stations and petroleum refineries has been carried out in previous studies using guideline values set by various agencies. In this work, health risk was characterized with the exposure data as cumulative probability distribution (CPD) plots but using human epidemiological data. This was achieved by using lowest observable adverse effects levels (LOAEL) data plotted as cumulative probability lowest effects distribution (CPLED). The health risk due to benzene was characterized by using probabilistic methods of hazard quotient (HQ 50/50 and HQ 95/5 ), Monte-Carlo simulation (MCS) and overall risk probability (ORP). CPD relationships of adverse health effects relationships and exposure data were in terms of average daily dose (ADD) and lifetime average daily dose (LADD) for benzene. For service station environments HQ 50/50 and HQ 95/5 were in a range of 0.000071-0.055 and 0.0049-21, respectively. On the other hand, the risk estimated for petroleum refinery environments suggests higher risk with HQ 50/50 and HQ 95/5 values ranging from 0.0012 to 77 and 0.17 to 560, respectively. The results of Monte-Carlo risk probability (MRP) and ORP indicated that workers in petroleum refineries (MRP of 2.9-56% and ORP of 4.6-52% of the affected population) were at a higher risk of adverse health effects from exposure to benzene as compared to exposure to benzene in service station environments (MRP of 0.051 -3.4% and ORP of 0.35-2.7% affected population). The adverse effect risk probabilities estimated by using the Monte-Carlo simulation technique and the ORP method were found to be generally consistent.

Highlights: Black-Right-Pointing-Pointer A UASB was successfully used for treatment of petroleum refinery effluent. Black-Right-Pointing-Pointer Response surface methodology was applied to design and analysis of experiments. Black-Right-Pointing-Pointer System was modeled between efficient factors include HRT, influent COD and V{sub up}. Black-Right-Pointing-Pointer UASB was able to remove about 76.3% influent COD at optimum conditions. - Abstract: An upflow anaerobic sludge blanket (UASB) bioreactor was successfully used for the treatment of petroleum refinery effluent. Before optimization, chemical oxygen demand (COD) removal was 81% at a constant organic loading rate (OLR) of 0.4 kg/m{sup 3} d and a hydraulic retention time (HRT) of 48 h. The rate of biogas production was 559 mL/h at an HRT of 40 h and an influent COD of 1000 mg/L. Response surface methodology (RSM) was applied to predict the behaviors of influent COD, upflow velocity (V{sub up}) and HRT in the bioreactor. RSM showed that the best models for COD removal and biogas production rate were the reduced quadratic and cubic models, respectively. The optimum region, identified based on two critical responses, was an influent COD of 630 mg/L, a V{sub up} of 0.27 m/h, and an HRT of 21.4 h. This resulted in a 76.3% COD removal efficiency and a 0.25 L biogas/L feed d biogas production rate.

The Tema Oil Refinery (TOR), which was commissioned in 1963, is a simple hydro-skimming plant which processes crude oil into LPG, gasoline, kerosene, gasoil, and fuel oil. It is the only petroleum refinery in Ghana. Over the years some of the equipment in the refinery has deteriorated or become obsolete necessitating major rehabilitation. A study of the refinery expansion project takes into consideration earlier studies and, equally important, recognizes the extensive work done by TOR in rehabilitating the refinery. The program, carried out in phases because of funding limitations, has addressed the critical repairs and replacements in the process units and utilities necessary to prolong the life of the refinery and assure reliability and safe operation. It undertook the task of investigating the feasibility of modernizing and expanding the refinery at Tema, Ghana to meet projected market demands until the year 2005. A process planning study was conducted to select the optimal process and utility configuration which would result in economic benefits to Ghana

The petroleum refining industry in the United States is the largest in the world, providing inputs to virtually any economic sector,including the transport sector and the chemical industry. The industry operates 146 refineries (as of January 2004) around the country,employing over 65,000 employees. The refining industry produces a mix of products with a total value exceeding $151 billion. Refineries spend typically 50 percent of cash operating costs (i.e., excluding capital costs and depreciation) on energy, making energy a major cost factor and also an important opportunity for cost reduction. Energy use is also a major source of emissions in the refinery industry making energy efficiency improvement an attractive opportunity to reduce emissions and operating costs. Voluntary government programs aim to assist industry to improve competitiveness through increased energy efficiency and reduced environmental impact. ENERGY STAR (R), a voluntary program managed by the U.S. Environmental Protection Agency, stresses the need for strong and strategic corporate energy management programs. ENERGY STAR provides energy management tools and strategies for successful corporate energy management programs. This Energy Guide describes research conducted to support ENERGY STAR and its work with the petroleum refining industry.This research provides information on potential energy efficiency opportunities for petroleum refineries. This Energy Guide introduces energy efficiency opportunities available for petroleum refineries. It begins with descriptions of the trends, structure, and production of the refining industry and the energy used in the refining and conversion processes. Specific energy savings for each energy efficiency measure based on case studies of plants and references to technical literature are provided. If available, typical payback periods are also listed. The Energy Guide draws upon the experiences with energy efficiency measures of petroleum refineries worldwide

A study of the technical and financial pre-feasibility is realized for the handling, conditioning and sale as fuel in cement industries of petroleum coke, that is produced in the project of extension and modernization of the refinery of RECOPE in Moin, Limon. Daily production has been of 570 metric tons. The market study has determined a demand of approximately 120 000 metric tons in the country and in the region. The total production of coke has been possible place it at national and regional level, due to lack of another producer. The coke is recommended to crush it to decrease the size of the particles for the conditioning, handling and to facilitate their manipulation. Conveyor belts are used for handling on the inside of the refinery. The coke is transported in trucks type tanker on the exterior of the refinery. The moisture content is reduced by dryer vibratory of fluidized bed to 5% of moisture to guarantee a product better quality. The product is stored under roof in ventilated facilities and with appropriate systems of security to minimize the risk of an accident. The fixed capital investment to develop the project has been of USD 3,1 millions and working capital of USD 14,4 millions. The financial evaluation is realized considering two financing models of 70% and without financing. The net present value (NPV) has been of USD -13,0 millions and the desirability index of -6,6 for the model with financing. The model without financing has obtained a NPV of USD -1,9 millions and a desirability index of -1,2. The financial profitability of the project has been very sensitive to the sales price of the coke, to the coke volume of production, to the growth percentage of the sale price and the cost of the raw material for the two models considered. The financial risk analysis is realized by the Monte Carlo method, whereupon is obtained a probability of approximately 34% in that the internal rate of return (IRR) has been higher than the cut rate and of 36% in that

Fuel specification, energy consumption and CO2 emission in oil refineries

International Nuclear Information System (INIS)

Szklo, Alexandre; Schaeffer, Roberto

2007-01-01

The more stringent environmental quality specifications for oil products worldwide are tending to step up energy use and, consequently, CO 2 emissions at refineries. In Brazil, for example, the stipulated reduction in the sulfur content of diesel and gasoline between 2002 and 2009 should increase the energy use of Brazil's refining industry by around 30%, with effects on its CO 2 emissions. Thus, the world refining industry must deal with trade-offs between emissions of pollutants with local impacts (due to fuel specifications) and emissions of pollutants with global impacts (due to the increased energy use at refineries to remove contaminants from oil products). Two promising technology options for refineries could ease this clash in the near-to-mid term: the reduction per se of the energy use at the refinery; and the development of treatment processes using non-hydrogen consuming techniques. For instance, in Brazilian refineries, the expanded energy use resulting from severe hydrotreatment to comply with the more stringent specifications of oil products may be almost completely offset by energy saving options and alternative desulfurization techniques, if barriers to invest in technological innovations are overcome.

Auxiliary units for refining of high nitrogen content oils: Premium II refinery case

Energy Technology Data Exchange (ETDEWEB)

Nicolato, Paolo Contim; Pinotti, Rafael [Petroleo Brasileiro S.A. (PETROBRAS), Rio de Janeiro, RJ (Brazil)

2012-07-01

PETROBRAS is constantly investing on its refining park in order to increase the production of clean and stable fuels and to be capable to process heavier oils with high contaminants content. Sulfur and nitrogen are the main heteroatoms present in petroleum. They are responsible for some undesirable fuels properties like corrosivity and instability, and also emit pollutants when burnt. Hydrotreating and hydrocracking processes are designed to remove these contaminants and adjust other fuel properties, generating, as byproduct, sour gases and sour water streams rich in H{sub 2}S and NH{sub 3}, which are usually sent to Sour Water Treatment Units and Sulfur Recovery Units. The regeneration of the amine used for the light streams treatment, as fuel gas and LPG, also generates sour gas streams that must be also sent to Sulfur Recovery Units. As the ammonia content in the sour streams increases, some design parameters must be adjusted to avoid increasing the Refinery emissions. Sulfur Recovery Units must provide proper NH3 destruction. Sour Water Treatment must have a proper segregation between H{sub 2}S and ammonia streams, whenever desirable. Amine Regeneration Systems must have an efficient procedure to avoid the ammonia concentration in the amine solution. This paper presents some solutions usually applied to the Petroleum Industry and analyses some aspects related to Premium II Refinery Project and how its design will help the Brazilian refining park to meet future environmental regulation and market demands.

Adoption of efficient process technologies is an important approach to reducing CO₂ emissions, in particular those associated with combustion. In many cases, implementing energy efficiency measures is among the most cost-effective approaches that any refiner can take, improving productivity while reducing emissions. Therefore, careful analysis of the options and costs associated with efficiency measures is required to establish sound carbon policies addressing global climate change, and is the primary focus of LBNL’s current petroleum refining sector analysis for the U.S. Environmental Protection Agency. The analysis is aimed at identifying energy efficiency-related measures and developing energy abatement supply curves and CO₂ emissions reduction potential for the U.S. refining industry. A refinery model has been developed for this purpose that is a notional aggregation of the U.S. petroleum refining sector. It consists of twelve processing units and account s for the additional energy requirements from steam generation, hydrogen production and water utilities required by each of the twelve processing units. The model is carbon and energy balanced such that crud e oil inputs and major refinery sector outputs (fuels) are benchmarked to 2010 data. Estimates of the current penetration for the identified energy efficiency measures benchmark the energy requirements to those reported in U.S. DOE 2010 data. The remaining energy efficiency potential for each of the measures is estimated and compared to U.S. DOE fuel prices resulting in estimates of cost- effective energy efficiency opportunities for each of the twelve major processes. A combined cost of conserved energy supply curve is also presented along with the CO₂ emissions abatement opportunities that exist in the U.S. petroleum refinery sector. Roughly 1,200 PJ per year of primary fuels savings and close to 500 GWh per y ear of electricity savings are potentially cost

This paper reports the development of a methodology for the determination of arsenic in petroleum refinery aqueous streams containing large amounts of unknown volatile organic compounds, employing electrothermal atomic absorption spectrometry with polarized Zeeman-effect background correction. In order to make the procedure applicable, the influence of chemical modification and the drying step was examined. Also, pyrolysis and atomization temperatures and the amount of nitric acid added to the sample were optimized using a multivariate approach based on Doehlert matrix. Obtained results indicate that, in this kind of sample, arsenic must be determined by standard addition procedure with a careful control of the drying step temperature and ramp pattern. In order to evaluate the accuracy of the procedure, a test was performed in six spiked samples of petroleum refinery aqueous streams and the relative errors verified in the analysis of such samples (added As between 12.5 and 190 μg l -1) ranged from -7.2 to +16.7%. The detection limit and the relative standard deviation were also calculated and the values are 68 pg and 7.5% (at 12.5 μg l -1 level), respectively.

In order to evaluate the accuracy of the procedure, a test was performed in six spiked samples of petroleum refinery aqueous streams and the relative errors verified in the analysis of such samples (added As between 12.5 and 190 μg l -1 ) ranged from -7.2 to +16.7%. The detection limit and the relative standard deviation were also calculated and the values are 68 pg and 7.5% (at 12.5 μg l -1 level), respectively

The allocation of CO 2 emissions of petroleum refineries to their oil products is a necessary step in the retrospective Well-to-Tank (WTT) analysis. These allocated emissions are used to evaluate the environmental impacts of automotive fuels' production within the refinery. Oil refining is a complex joint production system and there exists no simple and unique answer to this allocation question. Recently, Pierru proposed adapting the Aumann-Shapley cost sharing method to deal with this issue. Our paper aims at describing the conceptual and technical difficulties of this adaptation to the WTT context. Moreover, we show that this approach, as proposed by Pierru, is not applicable to any real-type refinery model. Different suggestions are provided to improve its applicability (when it is possible) in real situations. A simple numerical example as well as a real-type refinery case study is provided for illustrations. Finally, we discuss an alternative allocation approach which we believe more adapted to the WTT context. (author)

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

Joint refinery selenium treatability study

Meyer, C.L.; Folwarkow, S.

1993-01-01

The San Francisco Regional Water Quality Control Board recently established mass limits on discharges of selenium to the San Francisco Bay from several petroleum refineries. The refineries had been working independently to develop control strategies, including both source control and treatment options, for removal of selenium from their discharges. By January 1992, over fifty different combinations of treatment technologies, wastewater streams, and pretreatment steps had been investigated to determine their effectiveness and feasibility as selenium removal processes. No treatment process studied could achieve the required mass limits without serious negative environmental consequences, such as generation of large amounts of hazardous sludge. To better facilitate the development of a feasible selenium treatment process, the six Bay Area refineries shared results of their studies and identified several technologies that, with further work, could be developed further. This additional work is currently being carried out as part of a joint selenium treatability study sponsored by the Western States Petroleum Association. A review of the previous source control and treatment studies, along with a description of the current treatability studies will be discussed

During 20 years, refining has been the weak link of the petroleum industry. This sector has always suffered from a chronical overcapacity. Today, on the contrary, there is a lack of facilities and shortage is threatening. The Reichstett refinery (Alsace, France) is the smallest French refinery. It has been several times threatened with closure but today, thanks to the increasing demand, it works at full capacity. This short paper summarizes the history of this facility and its social and environmental impact in the region. (J.S.)

Increasingly strict environmental regulations have given rise to higher requirements for operating efficiency and optimization and water has become a vital resource in the refining process and allied industries. Due to this high demand for water, plants may be exposed to supply interruptions and shortages in the future. Major concerns in the petroleum refining industry are the scarcity of fresh water supply and increasingly rigid rules on wastewater discharge, which have resulted from concerns over the environmental impact. This paper presents the efforts made to develop an optimization framework for design of petroleum refinery water network systems and retrofitting that incorporates reuse, regeneration, and recycling strategies. This framework includes the complementary advantage of water pinch analysis (WPA). Water minimization strategies were incorporated as first postulates in a superstructural representation that includes all feasible flow-sheet options for taking advantage of water reuse, regeneration and recycling opportunities. Additionally, a post-optimization analysis was carried out to evaluate the repeated treatment processes required to identify the most efficient retrofit option.

Refining and blending of aviation turbine fuels.

Science.gov (United States)

White, R D

1999-02-01

Aviation turbine fuels (jet fuels) are similar to other petroleum products that have a boiling range of approximately 300F to 550F. Kerosene and No.1 grades of fuel oil, diesel fuel, and gas turbine oil share many similar physical and chemical properties with jet fuel. The similarity among these products should allow toxicology data on one material to be extrapolated to the others. Refineries in the USA manufacture jet fuel to meet industry standard specifications. Civilian aircraft primarily use Jet A or Jet A-1 fuel as defined by ASTM D 1655. Military aircraft use JP-5 or JP-8 fuel as defined by MIL-T-5624R or MIL-T-83133D respectively. The freezing point and flash point are the principle differences between the finished fuels. Common refinery processes that produce jet fuel include distillation, caustic treatment, hydrotreating, and hydrocracking. Each of these refining processes may be the final step to produce jet fuel. Sometimes blending of two or more of these refinery process streams are needed to produce jet fuel that meets the desired specifications. Chemical additives allowed for use in jet fuel are also defined in the product specifications. In many cases, the customer rather than the refinery will put additives into the fuel to meet their specific storage or flight condition requirements.

Refinery production planning and scheduling: the refining core business

Directory of Open Access Journals (Sweden)

M. Joly

2012-06-01

Full Text Available Intelligent production planning and scheduling are of paramount importance to ensure refinery profitability, logistic reliability and safety at the local and corporate levels. In Brazil, such activities play a particularly critical role, since the Brazilian downstream model is moving towards a demand-driven model rather than a supply-driven one. Moreover, new and specialized non-linear constraints are continuously being incorporated into these large-scale problems: increases in oil prices implying the need for processing poor quality crudes, increasing demand and new demand patterns for petroleum products, new stringent environmental regulations related to clean fuels and start-up of new production technologies embedded into more complex refining schemes. This paper aims at clarifying the central role of refinery planning and scheduling activities in the Petrobras refining business. Major past and present results are outlined and corporate long-term strategies to deal with present and future challenges are presented.

Water Pollution and Treatments Part II: Utilization of Agricultural Wastes to Remove Petroleum Oils From Refineries Pollutants Present in Waste Water

Ali, N.A.; El-Emary, M.M.

2011-01-01

Several natural agricultural wastes, of lignocellulose nature, such as Nile flower plant (ward El-Nil), milled green leaves, sugar cane wastes, palm tree leaves (carina), milled cotton stems, milled linseed stems, fine sawdust, coarse sawdust and palm tree cover were dried and then crushed to suitable size to be evaluated and utilized as adsorbents to remove oils floating or suspended in the waste water effluents from refineries and petroleum installations. The parameters investigated include effect of adsorbent type (adsorptive efficiency), adsorbate (type and concentration), mixing time, salinity of the water, adsorbent ratio to treated water, temperature, ph and stirring. Two different Egyptian crude oils varying in their properties and several refined products such as gasoline, kerosene, gas oil, diesel oil, fuel oil and lubricating oil were employed in this work in addition to the skimmed oil from the skim basin separator. Most of the agricultural wastes proved to be very effective in adsorbing oils from waste water effluents.

Petroleum refineries produce large amount of wastewaters, which often contain a wide range of different compounds. Some of these constituents may be recalcitrant and therefore difficult to be treated biologically. This study evaluated the capability of an aerobic submerged fixed-bed reactor (ASFBR) containing a corrugated PVC support material for biofilm attachment to treat a complex and high-strength organic wastewater coming from a petroleum refinery. The reactor operation was divided into five experimental runs which lasted more than 250 days. During the reactor operation, the applied volumetric organic load was varied within the range of 0.5-2.4 kgCOD.m(-3).d(-1). Despite the inherent fluctuations on the characteristics of the complex wastewater and the slight decrease in the reactor performance when the influent organic load was increased, the ASFBR showed good stability and allowed to reach chemical oxygen demand, dissolved organic carbon and total suspended solids removals up to 91%, 90% and 92%, respectively. Appreciable ammonium removal was obtained (around 90%). Some challenging aspects of reactor operation such as biofilm quantification and important biofilm constituents (e.g. polysaccharides (PS) and proteins (PT)) were also addressed in this work. Average PS/volatile attached solids (VAS) and PT/VAS ratios were around 6% and 50%, respectively. The support material promoted biofilm attachment without appreciable loss of solids and allowed long-term operation without clogging. Microscopic observations of the microbial community revealed great diversity of higher organisms, such as protozoa and rotifers, suggesting that toxic compounds found in the wastewater were possibly removed in the biofilm.

Petroleum industry: Development strategies to year 2000

International Nuclear Information System (INIS)

Curcio, E.

1993-01-01

During the last two years, the petroleum industry has undergone a period of modest demand increase on the international market, normal consumption rates by consuming countries and, faced with a growing supply base, a progressive per barrel unit price depreciation. In the refinery sector, margins have been reduced due to strong petroleum products price reductions. New anti-pollution laws have necessitated substantial investment in the development of cleaner fuels and pollution control technologies. The reorganization of the former USSR petroleum and gas sector should give rise to technology transfer opportunities for Western nations and spur gradual production increases especially in natural gas. Petroleum and gas demand increases are expected due to the modernization of China's industries. While it is clear that for the next decade their won't be any shortages in supply, forecasting petroleum prices to the year 2000 will remain clouded with uncertainty until such time as the national European petroleum industries decide to go ahead with their long awaited privatization and adjustments are made to current government and private sector energy strategies

Treatment of petroleum refinery sourwater by advanced oxidation processes

International Nuclear Information System (INIS)

Coelho, Alessandra; Castro, Antonio V.; Dezotti, Marcia; Sant'Anna, G.L.

2006-01-01

The performance of several oxidation processes to remove organic pollutants from sourwater was investigated. Sourwater is a specific stream of petroleum refineries, which contains slowly biodegradable compounds and toxic substances that impair the industrial biological wastewater treatment system. Preliminary experiments were conducted, using the following processes: H 2 O 2 , H 2 O 2 /UV, UV, photocatalysis, ozonation, Fenton and photo-Fenton. All processes, except Fenton and photo-Fenton, did not lead to satisfactory results, reducing at most 35% of the sourwater dissolved organic carbon (DOC). Thus, further experiments were performed with these two techniques to evaluate process conditions and organic matter removal kinetics. Batch experiments revealed that the Fenton reaction is very fast and reaches, in a few minutes, an ultimate DOC removal of 13-27%, due to the formation of iron complexes. Radiation for an additional period of 60 min can increase DOC removal up to 87%. Experiments were also conducted in a continuous mode, operating one 0.4 L Fenton stirred reactor and one 1.6 L photo-Fenton reactor in series. DOC removals above 75% were reached, when the reaction system was operated with hydraulic retention times (HRT) higher than 85 min. An empirical mathematical model was proposed to represent the DOC removal kinetics, allowing predicting process performance quite satisfactorily

Upgrading refineries performance: a necessity at the time of lean kine

The increasing problem of petroleum refining in Europe and France has been debated during a seminar organized by the ENSPM (Ecole Nationale Superieure des Petroles et Moteurs) Formation Industrie at Rueil-Malmaison (France) on June 15, 1995. For a new modern refinery, the processing cost for one ton of crude oil can reach 40 US $ and exceeds the refining gross profit. Introduction of unleaded gasoline and the forthcoming 0.05% sulfur gas oil represent additional investments of about 20 US $/t. The increasing production of lighter crude oils, which represent 2/3 of worldwide supplies, has increased the gas oil and fuel price difference. A better equilibrium between supply and demand and significant improvements of refineries performances are required to reduce processing costs. New methods and computerized systems have been developed in this way and presented during this seminar. (J.S.). 1 fig

Rationalization of imports, refineries and distribution of petroleum in Africa

International Nuclear Information System (INIS)

Mayorga-Alba, E.

1993-01-01

Petroleum products currently provide 69% of commercial energy requirements in Sub-Saharan Africa (SSA), or 21% of total primary energy consumption, including fuelwoods used for household energy needs - a proportion that will increase with the process of modernization in these economies and with the growing difficulties they are experiencing in financing projects for alternative commercial energy sources. In macro-economic terms, securing reliable and cheap petroleum product supplies is of vital importance for maintaining a sustainable level of economic growth. Petroleum products are an important tax base, contributing to nearly 40% of the fiscal revenues in Sub-Saharan countries. With the exceptions of Nigeria, Congo, Cameroon, Angola and Gabon, SSA countries are net importers of oil, devoting on average a third of their hard currency earnings to these imports. There is no other region in the world than SSA - with the lowest GDP per capita - that dependence on oil imports has become such a dominant factor in the macroeconomic calculus. The vulnerability of these economies, most of which depend heavily on donor financing for a large portion of their foreign exchange, can be directly assessed by understanding their increasing difficulty in assuring petroleum supplies. The use of petroleum products in SSA remains largely confined to the transport sector and to the existing light industry. Gasoline, jetfuel and diesel represent more than 2/3rds of the total petroleum consumption. The supply of households, which account for the largest portion of primary energy needs, is still based on fuelwoods and is growing beyond sustainable levels, posing an increasing threat to the environment. To respond to the deforestation problem and to facilitate the transition to more environmentally sound supply systems, African countries need to assess their capacity and means to increase their use of LPGs and other modern household fuels. 6 tabs

The treatment of synthetic oily wastewater having the characteristics of a typical petroleum refinery wastewater (PRW) by electrocoagulation (EC) using iron and aluminum electrodes was conducted in an electrolytic reactor equipped with fluid recirculation. During the treatment, the emulsion stability was followed by the measurement of Zeta potential and particle sizes. Effects of some operating conditions such as electrodes material, current density and electrolysis time on removal efficiencies of turbidity, and chemical oxygen demand (COD) were investigated in detail. The PRW purification by the EC process was found to be the most effective using aluminum as the anode and cathode, current density of 60 A/m(2) and 30 min of electrolysis time. Under these conditions, the process efficiencies were 83.52% and 99.94%, respectively, for COD and turbidity removals which correspond to final values of 96 mg O2/L and 0.5 NTU. A moderate energy consumption (0.341 kWh) was needed to treat 1 m(3) of PRW. Besides, the ecotoxicity test proved that toxic substances presented in the PRW, and those inhibiting the germination growth of whet, were eliminated by the EC technique.

A questionnaire study of men in a wastewater treatment plant of a petroleum refinery showed twice the rate of fetal loss in the period during employment in the plant compared with the periods before and after. Questions regarding the interpretation of that study and continuing concern about reproductive risk prompted us to perform a cross sectional evaluation of sperm concentration and morphology. After adjustment for an abstinence period, the mean sperm concentration of the 74 unexposed men did not differ significantly from that of the 34 exposed men (79.9 million/cm/sup 3/ v 68.2 million/cm/sup 3/, p(1) . 0.16). The two groups also had a similar proportion of sperm with abnormal morphology (49.1% v 44.5%, p(1) . 0.94). This lack of association remained when degree of exposure, age, use of alcohol and marijuana, past illness or fever, use of baths or sauna, and history of urological problems were considered. These results are most consistent with the absence of sperm mediated reproductive problems.

A circulating photocatalytic reactor was used for removing aliphatic and aromatic organic pollutants in refinery wastewater. The TiO 2 added wastewater samples, while saturating with air, were irradiated with an immersed mercury UV lamp (400 W, 200-550 nm). Optimal catalyst concentration, fluid pH and temperature were obtained at amounts of near 100 mg L -1 , 3 and 318 K, respectively. A maximum reduction in chemical oxygen demand of more than 90% was achieved after about 4 h irradiation and hence, 73% after about only 90 min; significant pollutant removal was also achievable in the other conditions. The identification of the organic pollutants, provided by means of a GC/MS and a GC analysis systems, equipped with headspace injection technique, showed that the major compounds were different fractions of petroleum aliphatic hydrocarbons (up to C 10 ) and the well-known aromatic compounds such as benzene, toluene and ethylbenzene. The results showed a high efficiency degradation of all of these pollutants

Gidarakos, E; Aivalioti, M

2007-11-19

This paper presents the course and the remediation results of a 4-year application of bioslurping technology on the subsurface of a Greek petroleum refinery, which is still under full operation and has important and complicated subsurface contamination problems, mainly due to the presence of light non-aqueous phase liquids (LNAPL). About 55 wells are connected to the central bioslurping unit, while a mobile bioslurping unit is also used whenever and wherever is necessary. Moreover, there are about 120 additional wells for the monitoring of the subsurface of the facilities that cover a total area of 1,000,000 m(2). An integrated monitoring program has also been developed and applied on the site, including frequent LNAPL layer depth and thickness measurements, conduction of bail-down and recovery tests, sampling and chemical analysis of the free oil phase, etc., so as to evaluate the remediation technique's efficiency and ensure a prompt tracing of any new potential leak. Despite the occurrence of new leaks within the last 4 years and the observed entrapment of LNAPL in the vadoze zone, bioslurping has managed to greatly restrict the original plume within certain and relatively small parts of the refinery facilities.

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 product slate of a simple refinery consists mainly of liquefied petroleum gas, leaded and unleaded gasoline, jet fuel, diesel fuel, extra light heating oil and fuel oil. The quality of the oil products (fuels) for sale has to comply with the adopted standards for liquid fuels, and the produced quantities have to be comply with the market needs. The oil products are manufactured by blending two or more different fractions which quantities and physical-chemical properties depend on the crude oil type, the way and conditions of processing, and at the same time the fractions are used to blend one or more products. It is in producer's interest to do the blending in an optimal way, namely, to satisfy the requirements for the oil products quality and quantity with a maximal usage of the available fractions and, of course, with a maximal profit out of the sold products. This could be accomplished by applying linear programming, that is by using a linear model for oil products blending optimization. (Author)

This study was performed to verify whether the exchange of the fuel used in the boilers of a crude oil refinery located in Cubatão (SE Brazil) would result in alterations on gas exchange, growth and leaf injuries in saplings of Psidium guajava 'Paluma'. The purpose of the refinery was to reduce the SO2 emission, but using natural gas as fuel could increase the concentrations of O3 precursors in the atmosphere. Thus a biomonitoring was performed with a native species sensitive to O3. The plants were exposed in five areas (CM1, CM5, CEPEMA, Centro, and RP) at different distances to the refinery, both before and after the fuel exchange. We performed six exposures under environmental conditions, with length of ca. 90 days each. With the utilization of natural gas, the saplings presented reductions in carbon assimilation rate under saturating light conditions (Asat, μmolCO2m(-2)s(-1)) and the stomatal conductance (gs, molH2Om(-2)s(-1)), and increase in height, number of leaves, and dry mass of leaves and shoots. There were also reductions in root dry mass and in the root/shoot ratio. The saplings also presented O3-induced leaf injuries. The responses of P. guajava 'Paluma' were altered after the fuel exchange as a result of a new combination of pollutants in the atmosphere. The fuel exchange has not resulted in environmental benefit to the surrounding forest; it has only altered the contamination profile of the region. Copyright © 2013 Elsevier Inc.

Impact of non-petroleum vehicle fuel economy on GHG mitigation potential

International Nuclear Information System (INIS)

Luk, Jason M; Saville, Bradley A; MacLean, Heather L

2016-01-01

The fuel economy of gasoline vehicles will increase to meet 2025 corporate average fuel economy standards (CAFE). However, dedicated compressed natural gas (CNG) and battery electric vehicles (BEV) already exceed future CAFE fuel economy targets because only 15% of non-petroleum energy use is accounted for when determining compliance. This study aims to inform stakeholders about the potential impact of CAFE on life cycle greenhouse gas (GHG) emissions, should non-petroleum fuel vehicles displace increasingly fuel efficient petroleum vehicles. The well-to-wheel GHG emissions of a set of hypothetical model year 2025 light-duty vehicles are estimated. A reference gasoline vehicle is designed to meet the 2025 fuel economy target within CAFE, and is compared to a set of dedicated CNG vehicles and BEVs with different fuel economy ratings, but all vehicles meet or exceed the fuel economy target due to the policy’s dedicated non-petroleum fuel vehicle incentives. Ownership costs and BEV driving ranges are estimated to provide context, as these can influence automaker and consumer decisions. The results show that CNG vehicles that have lower ownership costs than gasoline vehicles and BEVs with long distance driving ranges can exceed the 2025 CAFE fuel economy target. However, this could lead to lower efficiency CNG vehicles and heavier BEVs that have higher well-to-wheel GHG emissions than gasoline vehicles on a per km basis, even if the non-petroleum energy source is less carbon intensive on an energy equivalent basis. These changes could influence the effectiveness of low carbon fuel standards and are not precluded by the light-duty vehicle GHG emissions standards, which regulate tailpipe but not fuel production emissions.

A petroleum refinery model, Petroleum Refinery Life-cycle Inventory Model (PRELIM), that estimates energy use and CO 2 emissions was modified to evaluate the environmental and economic performance of a set of technologies to reduce CO 2 emissions at refineries. Cogeneration of heat and power (CHP), carbon capture at fluid catalytic cracker (FCC) and steam methane reformer (SMR) units, and alternative hydrogen production technologies were considered in the analysis. The results indicate that a 3-44% reduction in total annual refinery CO 2 emissions (2-24% reductions in the CO 2 emissions on a per barrel of crude oil processed) can be achieved in a medium conversion refinery that processes a typical U.S. crude slate obtained by using the technologies considered. A sensitivity analysis of the quality of input crude to a refinery, refinery configuration, and prices of natural gas and electricity revealed how the magnitude of possible CO 2 emissions reductions and the economic performance of the mitigation technologies can vary under different conditions. The analysis can help inform decision making related to investment decisions and CO 2 emissions policy in the refining sector.

Kuwait's downstream oil and gas industry, which sustained less damage than the country's oil field infrastructure during the Iraqi occupation of the 1990-91, has nearly completed reconstruction. Two of three refineries have resumed operations, one of them at reduced crude distillation rates. And state-owned Kuwait National Petroleum Co. hopes to put the other refinery, Shuaiba, back on stream in September, although not at preinvasion throughput rates. Major reconstruction will be complete by year end, with crude oil distillation capacity at 650,000 b/sd. Preinvasion crude capacities of Kuwait's refineries totaled 840,000 b/d. The article describes an overview of the recovery; the status of the Mina Abdulla processing plant, the Mina Al-Ahmadi refinery, and the Shuaiba refinery; modernization plans, and plans for petrochemicals

This paper describes a forty-two nonlinear equation model of the U.S. petroleum industry estimated over the period 1946 to 1973. The model specifies refinery outputs and prices as being simultaneously determined by market forces while the domestic output of crude oil is determined in a block-recursive segment of the model. The simultaneous behavioral equations are estimated with nonlinear two-stage least-squares adjusted to reflect the implications of autocorrelation for those equations where it appears to be a problem. A multi-period sample simulation, together with forecasts for 1974 and 1975 are used to evaluate the model's performance. Finally, it is used to forecast to 1985 under two scenarios and compared with the Federal Energy Administration's forecast for the same period. 2 figures, 8 tables, 38 references.

The overall objective of the bioremediation project is to provide a cost effective bioremediation demonstration of petroleum contaminated soil at the Czechowice Oil Refinery. Additional objectives include training of personnel, and transfer of this technology by example to Poland, and the Risk Abatement Center for Central and Eastern Europe (RACE). The goal of the remediation is to reduce the risk of PAH compounds in soil and provide a green zone (grassy area) adjacent to the site boundary. Initial project discussions with the Czechowice Oil Refinery resulted in helping the refinery find an immediate cost effective solution for the dense organic sludge in the lagoons. They found that when mixed with other waste materials, the sludge could be sold as a fuel source to local cement kilns. Thus the waste was incinerated and provided a revenue stream for the refinery to cleanup the lagoon. This allowed the bioremediation project to focus on remediation of contaminated soil that unusable as fuel, less recalcitrant and easier to handle and remediate. The assessment identified 19 compounds at the refinery that represented significant risk and would require remediation. These compounds consisted of metals, PAH's, and BTEX. The contaminated soil to be remediated in the bioremediation demonstration contains only PAH (BTEX and metals are not significantly above background concentrations). The final biopile design consists of (1) dewatering and clearing lagoon A to clean clay, (2) adding a 20 cm layer of dolomite with pipes for drainage, leachate collection, air injection, and pH adjustment, (3) adding a 1.1 m layer of contaminated soil mixed with wood chips to improve permeability, and (4) completing the surface with 20 cm of top soil planted with grass

Bio-jet fuels are emerging as a valuable alternative to petroleum-based fuels for their potential for reducing greenhouse gas emissions and fossil fuel dependence. In this study, residual woody biomass from slash piles in the U.S. Pacific Northwest is used as a feedstock to produce iso-paraffinic kerosene, through the production of sugar and subsequent patented proprietary fermentation and upgrading. To enhance the economic viability and reduce the environmental impacts of iso-paraffinic kerosene, two co-products, activated carbon and lignosulfonate, are simultaneously produced within the same bio-refinery. A cradle-to-grave life cycle assessment (LCA) is performed for the residual woody biomass-based bio-jet fuel and compared against the cradle-to-grave LCA of petroleum-based jet fuel. This paper also discusses the differences in the environmental impacts of the residual biomass-based bio-jet fuel using two different approaches, mass allocation and system expansion, to partition the impacts between the bio-fuel and the co-products, which are produced in the bio-refinery. The environmental assessment of biomass-based bio-jet fuel reveals an improvement along most critical environmental criteria, as compared to its petroleum-based counterpart. However, the results present significant differences in the environmental impact of biomass-based bio-jet fuel, based on the partitioning method adopted. The mass allocation approach shows a greater improvement along most of the environmental criteria, as compared to the system expansion approach. However, independent of the partitioning approach, the results of this study reveal that more than the EISA mandated 60% reduction in the global warming potential could be achieved by substituting petroleum-based jet fuel with residual woody biomass-based jet fuel. Converting residual woody biomass from slash piles into bio-jet fuel presents the additional benefit of avoiding the impacts of slash pile burning in the forest, which

Multi objective multi refinery optimization with environmental and catastrophic failure effects objectives

Petroleum refining is a capital-intensive business. With stringent environmental regulations on the processing industry and declining refining margins, political instability, increased risk of war and terrorist attacks in which refineries and fuel transportation grids may be targeted, higher pressures are exerted on refiners to optimize performance and find the best combination of feed and processes to produce salable products that meet stricter product specifications, while at the same time meeting refinery supply commitments and of course making profit. This is done through multi objective optimization. For corporate refining companies and at the national level, Intea-Refinery and Inter-Refinery optimization is the second step in optimizing the operation of the whole refining chain as a single system. Most refinery-wide optimization methods do not cover multiple objectives such as minimizing environmental impact, avoiding catastrophic failures, or enhancing product spec upgrade effects. This work starts by carrying out a refinery-wide, single objective optimization, and then moves to multi objective-single refinery optimization. The last step is multi objective-multi refinery optimization, the objectives of which are analysis of the effects of economic, environmental, product spec, strategic, and catastrophic failure. Simulation runs were carried out using both MATLAB and ASPEN PIMS utilizing nonlinear techniques to solve the optimization problem. The results addressed the need to debottleneck some refineries or transportation media in order to meet the demand for essential products under partial or total failure scenarios. They also addressed how importing some high spec products can help recover some of the losses and what is needed in order to accomplish this. In addition, the results showed nonlinear relations among local and global objectives for some refineries. The results demonstrate that refineries can have a local multi objective optimum that does not

Cellulosic and woody biomass can be converted to bio-oils containing less than 10% oxygen by a hydropyrolysis process. Hydropyrolysis is the first step in Gas Technology Institute’s (GTI) integrated Hydropyrolysis and Hydroconversion IH2®. These intermediate bio-oils can then be converted to drop-in hydrocarbon fuels using existing refinery hydrotreating equipment to make hydrocarbon blending components, which are fully compatible with existing fuels. Alternatively, cellulosic or woody biomass can directly be converted into drop-in hydrocarbon fuels containing less than 0.4% oxygen using the IH2 process located adjacent to a refinery or ethanol production facility. Many US oil refineries are actually located near biomass resources and are a logical location for a biomass to transportation fuel conversion process. The goal of this project was to work directly with an oil refinery partner, to determine the most attractive route and location for conversion of biorenewables to drop in fuels in their refinery and ethanol production network. Valero Energy Company, through its subsidiaries, has 12 US oil refineries and 11 ethanol production facilities, making them an ideal partner for this analysis. Valero is also part of a 50- 50 joint venture with Darling Ingredients called Diamond Green Diesel. Diamond Green Diesel’s production capacity is approximately 11,000 barrels per day of renewable diesel. The plant is located adjacent to Valero’s St Charles, Louisiana Refinery and converts recycled animal fats, used cooking oil, and waste corn oil into renewable diesel. This is the largest renewable diesel plant in the U.S. and has successfully operated for over 2 years For this project, 25 liters of hydropyrolysis oil from wood and 25 liters of hydropyrolysis oils from corn stover were produced. The hydropyrolysis oil produced had 4-10% oxygen. Metallurgical testing of hydropyrolysis liquids was completed by Oak Ridge National Laboratories (Oak Ridge) and showed the

Full Text Available The toxicity of phenol, 2-nitrophenol, 4-nitrophenol, 2,4-dinitrophenol, 2-chlorophenol, 4-chlorophenol, 4-bromophenol and 3,5-dimethylphenol on Pseudomonas, Bacillus and Escherichia species isolated from petroleum refinery wastewater was assessed via inhibition of dehydrogenase enzyme activity. At low concentrations, 2-nitrophenol, 2-chlorophenol, 4-chlorophenol, 4-bromophenol and 3,5-dimethylphenol stimulated dehydrogenase activity and at sufficient concentrations, phenolic compounds inhibited dehydrogenase activities. Generally, phenol is less toxic than substituted phenols. Estimations of the degree of inhibition/stimulation of dehydrogenase activities showed significant dose-dependent responses that are describable by logistic functions. The toxicity thresholds varied significantly (P < 0.05 among the bacterial strains and phenolic compounds. The median inhibitory concentrations (IC50s ranged from 4.118 ± 0.097 mg.L-1 for 4-nitrophenol against Pseudomonas sp. DAF1 to 1407.997 ± 7.091 mg.L-1 for phenol against Bacillus sp. DISK1. This study suggested that the organisms have moderate sensitivity to phenols and have the potential to be used as indicators for assessment of chemical toxicity. They could also be used as catalysts for degradation of phenols in effluents.

Clean-up of contaminated wastewater remains to be a major challenge in petroleum refinery. Here, we describe the capacity of a bacterial consortium enriched from crude oil drilling site in Al-Khobar, Saudi Arabia, to utilize polycyclic aromatic hydrocarbons (PAHs) as sole carbon source at 60°C. The consortium reduced low molecular weight (LMW; naphthalene, phenanthrene, fluorene and anthracene) and high molecular weight (HMW; pyrene, benzo(e)pyrene and benzo(k)fluoranthene) PAH loads of up to 1.5 g/L with removal efficiencies of 90% and 80% within 10 days. PAH biodegradation was verified by the presence of PAH metabolites and evolution of carbon dioxide (90 ± 3%). Biodegradation led to a reduction of the surface tension to 34 ± 1 mN/m thus suggesting biosurfactant production by the consortium. Phylogenetic analysis of the consortium revealed the presence of the thermophilic PAH degrader Pseudomonas aeruginosa strain CEES1 (KU664514) and Bacillus thermosaudia (KU664515) strain CEES2. The consortium was further found to treat petroleum wastewater in continuous stirred tank reactor with 96 ± 2% chemical oxygen demand removal and complete PAH degradation in 24 days.

Place of petroleum in the U. K. fuel market. [In relation to electricity, gas, and coal

Energy Technology Data Exchange (ETDEWEB)

An attempt is made to study the interaction process that occurs between petroleum products and the remainder of the fuel market. Petroleum competes with electricity, gas, and coal as a source of fuel, and an assessment is made of the demand elasticities of its place in the fuel market. In the U.K. fuel market the question is to what extent petroleum is a substitute or complement to the others. Petroleum consumption constituted 25 percent in 1960 of the total fuel consumption and has grown constantly since. The extent to which it changes depends upon its close substitutes. Which out of gas, coal, and electricity is, in fact, the closest substitute for petroleum; is it sensitive to price or to other things. In order to attempt to answer these questions, two models are presented. The first presents a straightforward linear equation for the demand for petroleum due to a change in total fuel consumption. This is then used in Model 2, which is basically the Slutsky equation, to obtain the mean substitution effect between petroleum and coal, gas and electricity. This, then, measures the net substitution or complementarity between petroleum and the commodities mentioned. 11 references.

As a part of the basic research on joint project promotion, this feasibility study supposed introduction of IGCC (integrated gasification combined cycle) to Nanjing oil refinery of Jinling Petrochemical Corp. (JPC) in China, estimated the CO{sub 2} emission reduction effect by in-refinery efficient power generation using petroleum coke residue as fuel, and assessed the feasibility of the project together with a cost benefit. The feasibility study result showed the effectiveness of IGCC introduction to the oil refinery for reducing CO{sub 2} emissions, occupying the interest of JPC. However, Nanjing oil refinery already making a decision to adopt another system (BTG) answered that early adoption of this project is difficult. The feasibility study result also showed that efficient operation of IGCC is difficult because of lower generation efficiency of petroleum coke residue, and achievement of the supposed CO{sub 2} emission reduction effect and profitability is difficult. The project based on this feasibility study result is probably difficult to be realized. (NEDO)

Oil-refinery and automotive emissions of rare earth elements

1991-01-01

The concentration pattern of rare-earth elements (REEs) in emissions from oil refineries and newer-model automobiles shows a distortion from the crustal abundance pattern. The REEs arise from the zeolite cracking catalysts used in petroleum refining and emission-control substrates used in automobile catalytic converters, respectively. Ten petroleum cracking catalysts from four countries and 12 catalytic converters from five automobile manufacturers were characterized for their REE content. The cracking catalysts are highly enriched in light REEs, whereas the automobile catalysts are enriched primarily in Ce. Incorporation of zeolite catalysts into refined oil provides new atmospheric elemental signatures for tracing emissions from refineries and oil-fired power plants on a regional scale. Though both have enhanced La/REE ratios, emissions from these two sources can be distinguished by their La/V ratios. Although REE demand by the petroleum industry has dropped considerably in recent years, automobile catalytic converters containing REEs are expected to increase dramatically as more stringent emission regulations are adopted in Europe, Japan and the US

In order to evaluate the economic viability of the proposed Project, exhaustive engineering, cost analysis, and financial studies have been undertaken. This report presents the results of feasibility studies undertaken in geothermal resource, engineering, marketing financing, management, environment, and permits and approvals. The conclusion of these studies is that the Project is economically viable. US Alcohol Fuels is proceeding with its plans to construct and operate the Refinery.

Enterprise Integration of Management and Automation in a Refinery

Science.gov (United States)

Wang, Chengen

Traditionally, problems in a petroleum refinery were separately modeled and solved with respect to disciplines. The segregated implementations of various disciplinary technologies resulted in considerable barriers impeding the pursuit of global optimal performance. It is recognized that enterprise-wide integration of the managerial and automation systems is of fundamental significance for refineries to promptly respond to global market requirements. In this paper, the technical implementations are disciplinarily categorized into managerial and automatic systems. Then, typical managerial and automatic implementations in a refinery are depicted to give an insight perception of the heterogeneous data sources manipulated by these systems. Finally, an integration approach based on data reconciliation techniques is proposed to link up the heterogeneous data sources.

Evaluation of the European Union-United States oil and petroleum-based fuels trade potential in the context of the negotiated TTIP agreement

Directory of Open Access Journals (Sweden)

Olkuski Tadeusz

2017-01-01

Full Text Available The article evaluates the European Union-United States oil and petroleum-based fuels trade potential. The planned trade structure and balance according to IEA (International Energy Agency and IHS (IHS CERA www.ihs.com scenarios, the projected volume of imports and exports, and differences in price levels and costs are presented. The projected potential of the trade volume, taking into account the possible impact of the Transatlantic Trade and Investment Partnership (TTIP, is also presented. The analysis has shown that the elimination of trade barriers between the European Union and the United States would be more beneficial to US refineries. Due to the higher import tariffs to the EU, the potential benefits of US exporters are higher than those of the EU exporters to the US. This confirms the fears of European negotiators that some aspects of the agreement will have a negative impact on European businesses. However, in the case of petroleum products the TTIP agreement will have a negligible impact on increasing the export volume.

The oil refinery industry seeks solutions to reduce its water uptake and consumption by encouraging the reuse of internal streams and wastewater from treatment systems. After conventional treatment the petroleum refinery wastewater still contains a considerable quantity of recalcitrant organics and the adsorption on activated carbon is currently used in Brazilian refineries, although it is still expensive due to the difficulty of its regeneration. This study evaluated the use of adsorbent and ion exchange resins for the removal of organic matter from refinery wastewater after conventional treatment in order to verify its feasibility, applying successive resin regenerations and comparing the results with those obtained for activated carbon process. Adsorption isotherms experiments were used to evaluate commercial resins, and the most efficient was subjected to column experiments, where absorbance (ABS) and total organic carbon (TOC) removal were measured. The adsorption isotherm of the best resin showed an adsorptive capacity that was 55% lower than that of activated carbon. On the other hand, the column experiments indicated good removal efficiency, and the amount of TOC in the treated wastewater was as good as has been reported in the literature for activated carbon. The regeneration efficiency of the retained organics ranged from 57 to 94%, while regenerant consumption ranged from 12 to 79% above the amount recommended by the resin supplier for the removal of organic material from natural sources, showing the great resistance of these recalcitrant compounds to desorption. Finally, an estimate of the service life of the resin using intermediate regeneration conditions found it to be seven times higher than that of activated carbon when the latter is not regenerated.

2018-01-01

Full Text Available Petroleum Refinery wastewater is characterized by a high phenol content. Phenol is toxic and resistant to biological processes for treatment of the petroleum refinery wastewater. The combination of an AOP and a biological process can be used for treatment of the refinery wastewater. It is necessary to conduct a study to determine the appropriate condition of AOP to meet the phenol removal level. Two AOP configurations were investigated: H2O2 / UV and H2O2 / UV / O3. From each process samples, COD, phenol and pH were measured. The oxidation was carried out until the targeted phenol concentration of treated effluent were obtained. The better result obtained by using process H2O2 / UV / O3 with the H2O2 concentration 1000 ppm. After 120 minutes, the final target has been achieved in which phenol concentration of 37.5 mg/L or phenol degradation of 93.75%.

Application of NMR Spectroscopy in the Analysis of Petroleum Derivatives and Products

Directory of Open Access Journals (Sweden)

Parlov Vuković, J.

2012-11-01

Full Text Available Complex chemical composition and physical properties of oil and fuel make their complete cha racterization very difficult. Components present in oil and oil products differ in structure, size, po larity and functionality. The presence and structure of specific hydrocarbons in final products depend on the processing procedure and type of the fuel. In order to predict or improve fuel pro perties it is necessary to determine its composition. Thus, new and more sophisticated analytical methods and procedures are constantly being developed. NMR spectroscopy plays a significant role in analysis and identification of complex hydrocarbon mixtures of petroleum and petroleum products. In this review, we describe the application of NMR spectroscopy for analyzing gasoline and diesel fuels. Hence, by using NMR spectroscopy it is possible to determine gasoline composition and presence of benzene and oxygenates, as well as some important physical characteristics of gasoli ne such as the research octane number. An application of different NMR techniques made it pos sible to characterize diesel fuels and middle oil distillates from various refineries. Data so obtained can be used in combination with statistical methods to predict fuel properties and to monitor pro- duction processes in the petroleum industry. NMR spectroscopy has proven useful in analysis of FAME which has recently been used as an ecologically acceptable alternative fuel. Furthermore, techniques such as CP/MAS for characterization of solid state oil-geochemical samples are inclu- ded. Also, possibilities of using NMR spectroscopy in the analysis of polymeric additives are di- scussed.

This discussion of the Canadian petroleum industry for the year 1966 includes production statistics and operating procedures, reserve estimates, exploration and development, transportation, refining, and marketing. Most sectors of the Canadian industry had an excellent year in 1966, featured by continued exploration and development successes in the Rainbow Lake-Zama Lake region of northwestern Alberta and a record value of production that exceeded $900 million for all liquid hydrocarbons. Production of crude oil and natural gas liquids exceeded one million bopd. Crude oil producers supplied 58% of the total crude oil requirements for Canadian refineries. Oil reserves increased due primarily to the application of secondary recovery and the discovery of new reserves. Total pipeline construction decreased, and there was a small increase in refinery capacity.

There has been an increasing concern about the continuous and the sudden release of volatile organic pollutants from petroleum refineries and occupational and environmental exposures. Benzene is one of the most prevalent volatile compounds, and it has been addressed by many authors for its potential toxicity in occupational and environmental settings. Due to the complexities of sampling and analysis of benzene in routine and accidental situations, a reliable estimation of the benzene concentration in the outdoor setting of refinery using a computational fluid dynamics (CFD) could be instrumental for risk assessment of occupational exposure. In the present work, a computational fluid dynamic model was applied for exposure risk assessment with consideration of benzene being released continuously from a reforming unit of a refinery. For simulation of benzene dispersion, GAMBIT, FLUENT, and CFD post software are used as preprocessing, processing, and post-processing, respectively. Computational fluid dynamic validation was carried out by comparing the computed data with the experimental measurements. Eventually, chronic daily intake and lifetime cancer risk for routine operations through the two seasons of a year are estimated through the simulation model. Root mean square errors are 0.19 and 0.17 for wind speed and concentration, respectively. Lifetime risk assessments of workers are 0.4-3.8 and 0.0096-0.25 per 1000 workers in stable and unstable atmospheric conditions, respectively. Exposure risk is unacceptable for the head of shift work, chief engineer, and general workers in 141 days (38.77%) in a year. The results of this study show that computational fluid dynamics is a useful tool for modeling of benzene exposure in a complex geometry and can be used to estimate lifetime risks of occupation groups in a refinery setting.

In this study, the combustion characteristics and emissions of two different petroleum diesel fuels (No. 1 and No. 2) and biodiesel from soybean oil were compared. The tests were performed at steady state conditions in a four-cylinder turbocharged DI diesel engine at full load at 1400-rpm engine speed. The experimental results compared with No. 2 diesel fuel showed that biodiesel provided significant reductions in PM, CO, and unburned HC, the NO{sub x} increased by 11.2%. Biodiesel had a 13.8% increase in brake-specific fuel consumption due to its lower heating value. However, using No. 1 diesel fuel gave better emission results, NO{sub x} and brake-specific fuel consumption reduced by 16.1% and 1.2%, respectively. The values of the principal combustion characteristics of the biodiesel were obtained between two petroleum diesel fuels. The results indicated that biodiesel may be blended with No. 1 diesel fuel to be used without any modification on the engine. (author)

Air concentrations of and inhalation exposure to total petroleum hydrocarbons (TPH) and benzene was monitored separately at two oil refineries from 1977 to 2014. Prevention policies and control measures that may explain changes were surveyed. The aim was to evaluate how the application of of Occupational Health and Safety Assessment Series OHSAS 18001.04 principles as well as Environmental protection Agency EPA and European Oil Company Organisation for Environment, Health and Safety CONCAWE practices have influenced air concentrations. Benzene air concentrations declined in 11 of 17 units, six of which were associated with declining exposures. Benzene air concentrations declined across all units on average by 46%. This amounts to an average yearly decline of 1.7%. TPH air concentrations declined in 10 of 17 units, seven of which were associated with declining exposures. The average decline in TPH air concentrations was 49%, corresponding to 1.3% per year. As a result, average working day exposure in 10 of 17 units have declined significantly and today, benzene and TPH exposure in most units are well below 10% of the current Occupational Exposure Limit (OEL 8h :s). A decline in air concentrations have coincided with consistent implementation of control measures. Such measures include on-line monitoring of leaks; benzene recovery; floating container roofs; improved valves and seals; hermetic pumps; recovery of loading gases and instalment of torches in terminals; cutback in coke combustion; a new production line spanning directly from the dock to aromatics production; and recovery of loading gases in the doc. Other tools in exposure management include personal leak monitors, on-line measurements, monitoring campaigns, risk assessment, and availability and user training of protective equipment. However, improvements are still needed. Hydrocarbon or benzene air concentrations have not declined in 8 of 17 units, in some of which concentrations exceed 10% of the relevant

Full Text Available Microbial fuel cells (MFCs are an environmentally friendly technology that can recover electricity directly from several wastes at ambient temperatures. This work explores the use of mineral oil refinery wastewater as feedstock in single-chamber air-cathode MFC devices. A polymer inclusion membrane based on the ionic liquid methyltrioctylammonium chloride, [MTOA+][Cl−], at a concentration of 70% w/w, was used as separator, showing a good efficiency in power production and chemical oxygen demand (COD removal. The power and the chemical oxygen demand removal reached values of 45 mW/m3 and over 80%, respectively. The evolution of other parameters of the wastewater including nitrites, phosphates and sulphates were also studied. Kjeldahl nitrogen and sulphates were significantly reduced during MFC operation. The results show that mineral oil refinery wastewater can be used as feedstock in air breathing cathode-microbial fuel cells based on polymer ionic liquid inclusion membranes. This configuration could represent a good alternative for wastewater depuration while producing energy during the process.

Identification of genes and pathways related to phenol degradation in metagenomic libraries from petroleum refinery wastewater.

Directory of Open Access Journals (Sweden)

Cynthia C Silva

Full Text Available Two fosmid libraries, totaling 13,200 clones, were obtained from bioreactor sludge of petroleum refinery wastewater treatment system. The library screening based on PCR and biological activity assays revealed more than 400 positive clones for phenol degradation. From these, 100 clones were randomly selected for pyrosequencing in order to evaluate the genetic potential of the microorganisms present in wastewater treatment plant for biodegradation, focusing mainly on novel genes and pathways of phenol and aromatic compound degradation. The sequence analysis of selected clones yielded 129,635 reads at an estimated 17-fold coverage. The phylogenetic analysis showed Burkholderiales and Rhodocyclales as the most abundant orders among the selected fosmid clones. The MG-RAST analysis revealed a broad metabolic profile with important functions for wastewater treatment, including metabolism of aromatic compounds, nitrogen, sulphur and phosphorus. The predicted 2,276 proteins included phenol hydroxylases and cathecol 2,3- dioxygenases, involved in the catabolism of aromatic compounds, such as phenol, byphenol, benzoate and phenylpropanoid. The sequencing of one fosmid insert of 33 kb unraveled the gene that permitted the host, Escherichia coli EPI300, to grow in the presence of aromatic compounds. Additionally, the comparison of the whole fosmid sequence against bacterial genomes deposited in GenBank showed that about 90% of sequence showed no identity to known sequences of Proteobacteria deposited in the NCBI database. This study surveyed the functional potential of fosmid clones for aromatic compound degradation and contributed to our knowledge of the biodegradative capacity and pathways of microbial assemblages present in refinery wastewater treatment system.

1989-01-01

The Petroleum Association for Conservation of the Canadian Environment (PACE) is a national, nonprofit, voluntary association formed by integrated Canadian oil companies to deal with environmental and health issues common to the manufacturing and distribution of petroleum products. PACE makes interventions before government bodies on public policy issues, and conducts research programs in its field of interest. In 1989, PACE has represented the petroleum industry in two major public consultation exercises, one on NOx and volatile organic carbon management, and one on future vehicle emission programs. The occurrence of two major marine spills on the west coast prompted the formation of a task force to study the state of contingency planning and response capability in the Canadian petroleum products industry, and a number of opportunities for improvement were determined. PACE has an ongoing program to produce visual aids and manuals for training emergency response personnel and effluent treatment plant operators. Guidelines for waste mangement at petroleum refineries, published in 1986, were updated. A major continuing project is development of environmental performance measures for refineries and to provide guidelines for using hazardous materials. Research studies were conducted on topics including service station effluents, the costs of sulfur emission reductions by desulfurization of fuels, the use of passive hydrocarbon dosimetry, and bioremediation of contaminated groundwater.

Problems Caused by Microbes and Treatment Strategies Downstream Petroleum Microbiology - An Industry Perspective

Science.gov (United States)

McFarlane, Elaine

In the mid 1800's it was discovered that crude oil could be extracted and exploited to produce energy. However, it was the invention of the first four-stroke internal combustion engine in 1876 that transformed the petroleum industry from a localised to a global business (Dell and Rand, 2004). Crude oil is made into useable products at the refinery via separation, conversion and treatment processes. Separation starts with distillation where the crude is evaporated and condensed into fractions based on their boiling ranges (Fig. 19.1). As well as carbon and hydrogen, the fractions consist of sulphur, nitrogen and oxygen (present in low concentrations) and metals like copper and iron (in trace amounts). After separation, heavy fractions are converted into lighter ones using intense heat, pressure and a catalyst to speed up chemical reactions. Molecules like sulphur can then be stripped out by heat treatment under pressure with hydrogen. Injection of refinery additives makes a finished fuel. For example, static dissipator is added to Automotive Gas Oil (AGO) to reduce the risk of spark and explosion during fuel movements; middle distillate flow improver to improve low temperature operability and lubricity improver to lubricate engine components. Finally, fuel quality measurements are made to ensure that the finished fuel meets the relevant specification.

Optimization of operating conditions of distillation columns: an energy saving option in refinery industry

Directory of Open Access Journals (Sweden)

Alireza Fazlali

2010-01-01

Full Text Available While energy prices continue to climb, it conservation remains the prime concern for process industries. The daily growth of energy consumption throughout the world and the real necessity of providing it, shows that optimization of energy generation and consumption units is an economical and sometimes vital case. Hence, the optimization of a petroleum refinery is aimed towards great production and an increase in quality. In this research, the atmospheric distillation unit of the Iran-Arak-Shazand petroleum refinery was subject to optimization efforts. It was performed by the means of using a simulator with the aim to earn more overhead products. In the next step the optimization results from the simulators were carried out in the real world, at the above mentioned unit. Results demonstrate that the changes in the real operating conditions increase the overhead products with desirable quality. Finally, a net economical balance between the increments of the overhead products and the energy consumption shows an energy saving in this refinery.

Comprehensive review on toxicity of persistent organic pollutants from petroleum refinery waste and their degradation by microorganisms.

Science.gov (United States)

Varjani, Sunita J; Gnansounou, Edgard; Pandey, Ashok

2017-12-01

Control and prevention of environmental pollution has become a worldwide issue of concern. Aromatic hydrocarbons including benzene, toluene, ethyl benzene, xylene (BTEX) and polyaromatic hydrocarbons (PAHs) are persistent organic pollutants (POPs), released into the environment mainly by exploration activities of petroleum industry. These pollutants are mutagenic, carcinogenic, immunotoxic and teratogenic to lower and higher forms of life i.e. microorganisms to humans. According to the International Agency for Research on Cancer (IARC) and United States Environmental Protection Agency (U.S. EPA), Benzo[a]pyrene (BaP) is carcinogenic in laboratory animals and humans. Aromatic hydrocarbons are highly lipid soluble and thus readily absorbed from environment in gastrointestinal tract of mammals. Treatment and remediation of petroleum refinery waste have been shown either to reduce or to eliminate genotoxicity of these pollutants. Bioremediation by using microorganisms to treat this waste is showing a promising technology as it is safe and cost-effective option among various technologies tested. The main aim of this review is to provide contemporary information on variety of aromatic hydrocarbons present in crude oil (with special focus to mono- and poly-aromatic hydrocarbons), exposure routes and their adverse effects on humans. This review also provides a synthesis of scientific literature on remediation technologies available for aromatic hydrocarbons, knowledge gaps and future research developments in this field.

Maximizing petrochemicals from refineries

Energy Technology Data Exchange (ETDEWEB)

Glover, B.; Foley, T.; Frey, S. [UOP, Des Plaines, IL (United States)

2007-07-01

New fuel quality requirements and high growth rates for petrochemicals are providing both challenges and opportunities for refineries. A key challenge in refineries today is to improve of the value of the products from the FCC unit. In particular, light FCC naphtha and LCO are prime candidates for improved utilization. Processing options have been developed focusing on new opportunities for these traditional fuel components. The Total Petrochemicals/UOP Olefin Cracking Process cracks C4-C8 olefins to produce propylene and ethylene. This process can be integrated into FCC units running at all severity levels to produce valuable light olefins while reducing the olefin content of the light FCC naphtha. Integration of the Olefin Cracking Process with an FCC unit can be accomplished to allow a range of operating modes which can accommodate changing demand for propylene, cracked naphtha and alkylate. Other processes developed by UOP allow for upgrading LCO into a range of products including petrochemical grade xylenes, benzene, high cetane diesel and low sulfur high octane gasoline. Various processing options are available which allow the products from LCO conversion to be adjusted based on the needs and opportunities of an individual refinery, as well as the external petrochemical demand cycles. This presentation will examine recent refining and petrochemical trends and highlight new process technologies that can be used to generate additional revenue from petrochemical production while addressing evolving clean fuel demands.

This paper presents a summary of three projects at the Mobil Refinery in Torrance, California where bioremediation technologies were successfully employed for the remediation of hydrocarbon contaminated soil. The three projects represent variations of implementation of bioremediation, both in-situ and ex-situ. Soil from all of the projects was considered non-hazardous designated waste under the California Code of Regulations, Title 23, section 2522. The projects were permitted and cleanup requirements were defined with the Los Angeles Regional Water Quality Control Board. In all of the projects, different methods were used for supplying water, oxygen, and nutrients to the hydrocarbon degrading bacteria to stimulate growth. The Stormwater Retention Basin Project utilized in-situ mechanical mixing of soils to supply solid nutrients and oxygen, and a self-propelled irrigation system to supply water. The Tank Farm Lake project used an in-situ active bioventing technology to introduce oxygen, moisture, and vapor phase nutrients. The Tank 1340X247 project was an ex-situ bioventing remediation project using a drip irrigation system to supply water and dissolved nutrients, and a vapor extraction system to provide oxygen

Air concentrations of and inhalation exposure to total petroleum hydrocarbons (TPH) and benzene was monitored separately at two oil refineries from 1977 to 2014. Prevention policies and control measures that may explain changes were surveyed. The aim was to evaluate how the application of of Occupational Health and Safety Assessment Series OHSAS 18001.04 principles as well as Environmental protection Agency EPA and European Oil Company Organisation for Environment, Health and Safety CONCAWE practices have influenced air concentrations. Benzene air concentrations declined in 11 of 17 units, six of which were associated with declining exposures. Benzene air concentrations declined across all units on average by 46%. This amounts to an average yearly decline of 1.7%. TPH air concentrations declined in 10 of 17 units, seven of which were associated with declining exposures. The average decline in TPH air concentrations was 49%, corresponding to 1.3% per year. As a result, average working day exposure in 10 of 17 units have declined significantly and today, benzene and TPH exposure in most units are well below 10% of the current Occupational Exposure Limit (OEL8h:s). A decline in air concentrations have coincided with consistent implementation of control measures. Such measures include on-line monitoring of leaks; benzene recovery; floating container roofs; improved valves and seals; hermetic pumps; recovery of loading gases and instalment of torches in terminals; cutback in coke combustion; a new production line spanning directly from the dock to aromatics production; and recovery of loading gases in the doc. Other tools in exposure management include personal leak monitors, on-line measurements, monitoring campaigns, risk assessment, and availability and user training of protective equipment. However, improvements are still needed. Hydrocarbon or benzene air concentrations have not declined in 8 of 17 units, in some of which concentrations exceed 10% of the relevant

The production of heavy crude oils is projected to continue to grow in the upstream oil industry given that large reserves of unconventional extra heavy crude and bitumen exist in several geographic areas including Canada and Venezuela. As reserves of conventional crude oil continue to decline, these unconventional feedstocks are becoming an opportunity to pursue, but they require effective technologies for upgrading and meeting the growing demand for light and middle distillate fuels. This paper described the proprietary technology that offers a solution to upstream and downstream oil producers for bottom-of-the-barrel upgrading. En i Slurry Technology (EST) is constructing an industrial plant in its Sannazzaro refinery in Italy. The plant is designed to convert 23,000 BPSD of vacuum residue into high quality diesel and other valuable refinery streams such as liquefied petroleum gas, naphtha and jet fuel. EST is an H-addition process characterized by the use of a special homogeneous isothermal intrinsically safe reactor, and of a nano-dispersed non-ageing catalyst. EST converts more than 98 per cent of any type of residues to about 110 per cent volume of light products and distillates or extra heavy oils to high quality bottomless SCO. In typical performance, HDS is greater than 85 per cent, HDM greater than 99 per cent and HDCCR greater than 97 per cent. EST also achieves the target of zero fuel oil - zero coke. 12 refs., 4 tabs., 5 figs.

In 2000, the Russian Federation implemented measures to increase oil production in the Chechen Republic from 73 thousand metric tons to 1.5 million metric tons by 2002. As a result, the oil refining industry in the Chechen Republic is currently in a state of crisis. More advanced and effective refining processes are required along with a reduction in production costs. The reconstruction program for refineries in Grozny requires new process system designs that can handle the appropriate petroleum products in the correct quantities and required qualities. There is also a need to balance the use of natural resources with fixed facilities and operating costs. The challenge to design optimal process systems for refineries in Grozny is both multicriterial and complex. The design will have to consider the use of various crudes and petroleum products. Advances in refining capability and resource conservation technologies would lead to greater energy consumption resulting from additional petroleum production.

1996-01-01

Amoco's Yorktown, Virginia, refinery is a 35-year-old, 53,000 bbl/day facility that manufacturers gasoline, heating oil, liquid petroleum gas, sulfur, and coke. In a cooperative and voluntary effort, Amoco Corporation and the US Environmental Protection Agency conducted a joint project to study pollution prevention opportunities at an operating industrial facility. Source reduction efforts--key to pollution prevention strategies--require knowledge of specific sources of releases. However, data on releases from individual process units are limited in favor of data to monitor existing end-of-pipe pollution control requirements. The study's sampling program sought to portray the distribution of releases within the refinery, their management within the refinery, and ultimate releases leaving the refinery. Subsequent tests of blowdown stack and fugitive emissions further improved total release estimates. The initial study estimated that the refinery generates about 25,000 metric tons (t)/year of potential pollutants. Of these, about half are released from the refinery as airborne, waterborne, or land-disposed releases. Airborne releases comprise the majority of releases by mass, about 12,000 t/year. Most of the airborne releases are volatile organic compound hydrocarbons. The inventory sampling project and subsequent work identified differences with Toxic Release Inventory (TRI) values and standard emission factors (AP-42). The inventory and other data provided an opportunity to consider options for, and limitations of, specific pollution prevention or source reduction strategies

Predicting refinery effluent toxicity on the basis of hydrocarbon composition determined by GCxGC analysis

Energy Technology Data Exchange (ETDEWEB)

Whale, G. [and others

2013-04-15

A high resolution analytical method for determining hydrocarbon blocks in petroleum products by comprehensive two-dimensional gas chromatography (GCxGC) was used for the analysis of petroleum hydrocarbons extracted from refinery effluents. From 105 CONCAWE refineries in Europe 111 refinery effluents were collected in the period June 2008 to March 2009 (CONCAWE, 2010). The effluents were analysed for metals, standard effluent parameters (including Chemical Oxygen Demand (COD), Biochemical Oxygen Demand (BOD), oil in water (OiW), GCxGC speciated hydrocarbons, BTEX (Benzene, Toluene, Ethylbenzene, and Xylenes) and volatile organic compounds. This report describes the subsequent analysis of the GCxGC data, as described in hydrocarbon blocks, and uses the PETROTOX model, to predict the environmental toxicity (i.e. ecotoxicity) of the discharged effluents. A further analysis was undertaken to address the potential environmental impact of these predicted effects initially using default dilution factors and then,when necessary site specific factors. The report describes all the methods used to arrive at the predictions, and shows that for the majority of refinery effluents direct toxicity effects in the effluents are not anticipated. Furthermore, when applying either the EU Risk Assessment Technical Guidance Document (TGD) default dilution factors or site specific dilution factors, none of the refineries are predicted to exerting either acute or chronic toxicity to organisms in the receiving aquatic environment, based on their hydrocarbon composition present in the effluent samples.

Cleaner shipping. Trade off between air pollution, costs and refinery CO2 emissions

De Wilde, H.P.J.; Kroon, P.

2008-05-01

Still subject to final approval in October 2008, the International Maritime Organisation (IMO) agreed on a maximum sulphur content of 0.5% for shipping fuels in 2020. This target will induce major changes in the global refinery industry. We have estimated the impact on the Dutch refinery industry, which annually produces about 8 million tons of heavy fuel oil for sea shipping, with refinery residues as main component. It is technically possible to convert all residues, although this process will cause an additional energy use of about one million tons of crude oil and a related CO2 emission of about 4 million tons. The investment costs for these major changes in the Dutch refinery industry are estimated at about 1.5 tot 2 billion euros. The recent IMO agreement enables a gradual introduction of cleaner shipping fuels, which will reduce market disruptions and peak prices. Nevertheless, Rotterdam may not necessarily be able to develop a similar position in import, export and bunkering of future low sulphur fuels, compared to its present strong position in the market of heavy marine bunkers. Extrapolation of our national study to the global scale suggests that the deep conversion of 350 million tons of heavy fuel oil for shipping would require refinery investments in the order of 70-100 billion euros. The associated CO2 emissions would amount up to 175 Mton. The net additional CO2 emission, however, would be smaller since lighter shipping fuels result in less CO2 emissions at sea. On balance, we expect that the improvements in fuel economy, driven by the expensive low-carbon shipping fuels, will decrease CO2 emissions more than the increase in CO2 emissions from additional desulphurization in the refineries. Nevertheless CO2 emissions from sea shipping will continue to increase since marine transport is rapidly growing

Mesocosm trials of bioremediation of contaminated soil of a petroleum refinery: comparison of natural attenuation, biostimulation and bioaugmentation.

Contamination with petroleum hydrocarbons (PHC) is a global problem with environmental implications. Physico-chemical treatments can be used for soil cleanup, but they are expensive, and can have implications for soil structure and environment. Otherwise, biological remediation treatments are cost-effective and restore soil structure. Several remediation experiments have been carried out in the lab and in the field; however, there is the challenge to achieve as good or better results in the field as in the laboratory. In the ambit of a project aiming at investigating suitable biological remediation approaches for recovering a refinery contaminated soil, we present here results obtained in bioremediation trials. The approaches biostimulation and bioaugmentation were tested, in parallel, and compared with natural attenuation. For this purpose, mesocosm experiments were carried out inside the refinery area, which constitutes a real asset of this work. Soil contaminated with crude oil was excavated, re-contaminated with turbine oil, homogenised and used to fill several 0.5 m(3) high-density polyethylene containers. The efficiency of procedures as follows: (1) natural attenuation; (2) manual aeration; (3) biostimulation by adding (3.1) only nutrients; and (3.2) nutrients and a non-ionic surfactant; and (4) bioaugmentation in the presence of added (4.1) nutrients or (4.2) nutrients and a non-ionic surfactant were evaluated after a 9-month period of experiment. For bioaugmentation, a commercial bacterial product was used. In addition to physico-chemical characterization, initial and final soil contents in total petroleum hydrocarbons (TPH) (by Fourier transform infrared spectrophotometry) and the total number of bacteria (by total cell counts) were carried out. For TPH degradation evaluation the soil was divided in four fractions corresponding to different depths: 0-5; 5-10; 10-15; and 15-20 cm. Mean values of percentages of PHC degradation varied between 20 and 50% at

Economic forces push down selling prices of U.S. refineries

International Nuclear Information System (INIS)

Anon.

1996-01-01

Recent data on US refinery sales reveal that selling prices have continued to decline in the 1990s. Reasons for this decrease include increased plant investments to meet regulatory requirements, excess refining capacity, increased imports of refined products, and reduced margins. While these expenditures enable a refinery to continue operating, they do not make the refinery more profitable or valuable. Other factors contributing to reduced selling prices of US refineries are: declining local crude production; unstable crude costs; increased energy conservation; growing competition from alternative fuels

This activity was begun with the assembly of information from Parsons' files and from contacts in the development and commercial fields. A further more extensive literature search was carried out using the Energy Data Base and the American Petroleum Institute Data Base. These are part of the DOE/RECON system. Approximately 6000 references and abstracts were obtained from the EDB search. These were reviewed and the especially pertinent documents, approximately 300, were acquired in the form of paper copy or microfiche. A Fuel Properties form was developed for listing information pertinent to gas turbine liquid fuel properties specifications. Fuel properties data for liquid fuels from selected synfuel processes, deemed to be successful candidates for near future commercial plants were tabulated on the forms. The processes selected consisted of H-Coal, SRC-II and Exxon Donor Solvent (EDS) coal liquefaction processes plus Paraho and Tosco shale oil processes. Fuel properties analyses for crude and distillate syncrude process products are contained in Section 2. Analyses representing synthetic fuels given refinery treatments, mostly bench scale hydrotreating, are contained in Section 3. Section 4 discusses gas turbine fuel specifications based on petroleum source fuels as developed by the major gas turbine manufacturers. Section 5 presents the on-site gas turbine fuel treatments applicable to petroleum base fuels impurities content in order to prevent adverse contaminant effects. Section 7 relates the environmental aspects of gas turbine fuel usage and combustion performance. It appears that the near future stationary industrial gas turbine fuel market will require that some of the synthetic fuels be refined to the point that they resemble petroleum based fuels.

Liu, Jin’e; Lin, Bin-Le; Sagisaka, Masayuki

2012-01-01

To promote the reduction of greenhouse gas emissions, research and development of bioethanol technologies are encouraged in Japan and a plan to utilize untilled fields to develop rice for bioethanol production as a substitute for petroleum fuel is being devised. This study applies emergy methods to compare the sustainability of petroleum fuel production and two Japanese rice-to-ethanol production scenarios: (a) ethanol from rice grain, while straw and chaff are burned as energy and (b) ethanol from rice+straw+chaff. The major emergy indices, Emergy Yield Ratio (EYR), Environmental Loading Ratio (ELR), Emergy Investment Ratio (EIR), Emergy Sustainability Index (ESI), Environmental Impacts Ratio (EVR) and system transformity (Tr), are analyzed to assess the production processes. The results show that (1) petroleum fuel production presents higher ELR, EIR, EVR and lower EYR, ESI, Tr than rice-to-ethanol production, indicating rice-to-ethanol production makes sense for reduction of greenhouse gases (GHG); (2) scenario (a) performs similarly on major indicators (EYR, ESI, ELR, EIR and EVR) to scenario (b), yet the system efficiency indicator (Tr) of scenario (a, 7.572×10 5 semj/J) is much higher than (b, 4.573×10 5 semj/J), and therefore (b) is a better alternative for policy decisions; (3) both petroleum fuel production and rice-to-ethanol processes are mainly driven by purchased resources and are unsustainable and nonrenewable in the long run. - Highlights: ► We compare petrol fuel and rice-to-ethanol production using emergy indices. ► Rice-to-ethanol reduces green house gas emissions as a substitute for petrol fuel. ► Rice-to-ethanol production has better sustainability than that of petrol fuel. ► Neither petrol fuel nor biofuel production are sustainable in the long term. ► Bioethanol is not a renewable fuel.

Hydroprocessing and premium II refinery: a new refining philosophy for an era of clean fuels

Delgaudio, Caio Veiga Penna; Pinotti, Rafael [Petroleo Brasileiro S.A. (PETROBRAS), Rio de Janeiro, RJ (Brazil)

2012-07-01

This paper discusses a brief history of Brazilian's emission and fuel specifications, since the appearance of PROCONVE until the late stages of the program for vehicles powered by gasoline and diesel. The development of the Brazilian refining is analyzed taking into account the emission and specification evolutions, and it can be perceived that the system's complexity increases while new constraints are imposed by the regulator. This aspect is even more apparent when the detailed scheme of the Premium II refinery and its main unit, the catalytic hydrocracker (HCC, which has not yet been part of PETROBRAS' refining park and will appear in three of the four new refineries of the company) is described. The new projects represent the culmination of the intensive use of energy and raw material for obtaining the products with the new specifications. There is a price for this development, both in investments and increased operating costs due to greater complexity of the system. To adapt to the era of clean fuels, refiners will present a series of challenges that will lead them to seek for more efficient processes and operational excellence (and ongoing efforts to reduce their emissions) in order to ensure positive refining margins.

The life and times of a western refinery

Thomas, W.

1998-01-01

An historical account is given of the discovery of oil by Imperial Oil Ltd., at Leduc in 1947, and the opening of a refinery in Edmonton in 1948. The discovery at Leduc was the first major strike to be made in western Canada, but Imperial Oil did not have a refinery at the site to process the new found crude. Given the economic constraints of the postwar era, Imperial Oil decided to dismantle and move an idle and virtually brand-new refinery located at Whitehorse, Yukon. It took 10 months to reassemble the refinery at its newly prepared site at Edmonton. Regular expansions and improvements helped to ensure that the refinery kept up with the advances in technology and market demand. By the early 1970s, small refineries were becoming uneconomical as distribution of products by pipelines became possible. In 1976 Imperial Oil spent more than $300 million to consolidate its four Prairie refineries, those in Calgary, Winnipeg, Regina and Edmonton, into one large facility at the Edmonton site. The role that the refinery plays in today's community and the effort that Imperial Oil makes to comply with stringent environmental regulations were described. Today, the refinery is producing 165,000 barrels a day of fuels and lubricants and another 20,000 barrels of asphalt. The refinery supplies more than 200 different products to customers across Canada, with unit costs which are amongst the lowest of North American refineries. figs

Assessment of accidental refinery wastewater discharge: a case study

Bandyopadhyay, Amitava [University of Calcutta, Department of Chemical Engineering, Kolkata (India)

2011-04-15

The physicochemical qualities of an accidental discharge of refinery liquid waste, water, and soil sediment of that effluent-receiving water body (canal) were investigated. Analyses of the discharge, qualities of water, and sediment of the canal showed high parametric concentrations. Investigations revealed that the discharge took place form the spent caustic that was generated from the caustic wash tower of Fluidized Catalytic Cracker of the refinery. A simple but realistic model was suggested for the remediation of sediments of the canal with an estimated cost of about US $1.86 million. Recommendations were made to prevent such discharges and to revise thoroughly the Indian effluent discharge standards in force for petroleum oil refinery. Subsequently, revised standards were notified under Indian guidelines. Interestingly, cyanide besides many other parameters was introduced into these standards. Furthermore, Volatile Organic Compound (VOC) was also stipulated as an emission parameter from the waste water treatment plants. Concentration- and mass-based standards thus promulgated were stricter than the existing standards. (orig.)

Hydrogen management in the MiRO refinery

Neumann, G. [Mineraloelraffinerie Oberrhein GmbH und Co. KG, Karlsruhe (Germany)

2010-12-30

The importance of hydrogen in refineries has increased over the last 20 years as new regulations affecting gasoline and diesel composition have been implemented throughout Europe and in an environment of increasingly stringent clean fuel regulations, decreasing heavy fuel oil demand and increasing heavy more sour crude supply. In Germany, the introduction of sulphur free gasoline and diesel with less than 10ppm sulphur(Auto Oil Program) and light home fuel oil with less than 50ppm this year were the last link in a long chain of environmental regulations, which had a considerable effect on the hydrogen demand in refineries. In the complex MiRO-refinery with a large FCC- and Coker-Unit for atmospheric residue conversion and a total throughput of more than 15 Mio.T/ a and more than 14 Mio.T/a crude oils of different origin from high sulphur, bituminous crudes to medium, low sulphur crudes for calcinate-production from green coke the only source of hydrogen for a long time was catalytic reforming. The only chance of balancing the hydrogen production and consumption was to improve the existing catalytic reforming and the optimisation of hydrogen recovery from waste or purge streams and the hydrogen network of the refinery. In 2007 a new hydrogen plant via steam reforming of natural gas went on stream. The main reason for this step was the shrinking market for gasoline in the last ten years and the blending of bio-ethanol into the gasoline pool, which released reforming capacities and the demand for octane. Another important issue is the production planning taking into account the potentials of hydrogen production via catalytic and steam reforming and the hydrogen consumption via desulphurisation and the saturation of olefins and (poly-)aromatics of the main product streams, gasoline, diesel and light home fuel oil.

South Africa's refineries: waiting for Maduna

International Nuclear Information System (INIS)

Anon.

1997-01-01

A definitive energy policy from the new Energy Minister, Penuell Maduna, is awaited by the petroleum industry in South Africa. Some of the complexities of the South African oil market and past legacies which make the task of producing a policy difficult, are examined here. They include the allegations made initially in 1994 that oil refineries are illegally repatriating profits by paying too much for imported products. Accusations of this transfer pricing have resurfaced in the light of recent figures published by the South African Petroleum Industry Association (SAPIA) which show that the oil industry's profitability is not as high as some had presumed. However, compelling evidence for the allegations has not appeared and it is unlikely that the foreign investors in SAPIA would endanger their operations in this way. SAPIA members are key investors in the national infrastructure and make large tax contributions much needed by the treasury. In its turn, SAPIA is unhappy about the continuation of the payment of large taxpayer funded subsidies to the privatised Sasol, the South African synthetic fuel company, seeing as anti-competitive and having negative implications for the national economy. For its part Sasol argues its entitlement to the same tariff protection enjoyed by 80% of local manufacturing industries in South Africa. Some government action has been taken to reduce the subsidies though. The oil companies in SAPIA require clarity on future energy policy and deregulation before committing themselves to further heavy capital investment and Sasol also requires an end to the present uncertainties.

Highlights: • Effective degradation of petroleum hydrocarbon mixtures was achieved using MFC. • Adapted anaerobic microbial consortium was used as inoculum. • Bio-electricity generation was enhanced by 30-fold when riboflavin, was added. • Optimum MFC performance was obtained at mesophilic and moderately saline conditions. • Stable MFC performance was obtained during prolonged fed-batch MFC operation. - Abstract: Microbial fuel cells (MFCs) need to be robust if they are to be applied in the field for bioremediation. This study investigated the effect of temperature (20–50 °C), salinity (0.5–2.5% (w/v) as sodium chloride), the use of redox mediators (riboflavin and anthraquinone-2-sulphonate, AQS) and prolonged fed-batch operation (60 days) on biodegradation of a petroleum hydrocarbon mix (i.e. phenanthrene and benzene) in MFCs. The performance criteria were degradation efficiency, % COD removal and electrochemical performance. Good electrochemical and degradation performance were maintained up to a salinity of 1.5% (w/v) but deteriorated by 35-fold and 4-fold respectively as salinity was raised to 2.5%w/v. Degradation rates and maximum power density were both improved by approximately 2-fold at 40 °C compared to MFC performance at 30 °C but decreased sharply by 4-fold when operating temperature was raised to 50 °C. The optimum reactor performance obtained at 40 °C was 1.15 mW/m{sup 2} maximum power density, 89.1% COD removal and a degradation efficiency of 97.10%; at moderately saline (1% w/v) conditions the maximum power density was 1.06 mW/m{sup 2}, 79.1% COD removal and 91.6% degradation efficiency. This work suggests the possible application of MFC technology in the effective treatment of petroleum hydrocarbons contaminated site and refinery effluents.

Highlights: • Effective degradation of petroleum hydrocarbon mixtures was achieved using MFC. • Adapted anaerobic microbial consortium was used as inoculum. • Bio-electricity generation was enhanced by 30-fold when riboflavin, was added. • Optimum MFC performance was obtained at mesophilic and moderately saline conditions. • Stable MFC performance was obtained during prolonged fed-batch MFC operation. - Abstract: Microbial fuel cells (MFCs) need to be robust if they are to be applied in the field for bioremediation. This study investigated the effect of temperature (20–50 °C), salinity (0.5–2.5% (w/v) as sodium chloride), the use of redox mediators (riboflavin and anthraquinone-2-sulphonate, AQS) and prolonged fed-batch operation (60 days) on biodegradation of a petroleum hydrocarbon mix (i.e. phenanthrene and benzene) in MFCs. The performance criteria were degradation efficiency, % COD removal and electrochemical performance. Good electrochemical and degradation performance were maintained up to a salinity of 1.5% (w/v) but deteriorated by 35-fold and 4-fold respectively as salinity was raised to 2.5%w/v. Degradation rates and maximum power density were both improved by approximately 2-fold at 40 °C compared to MFC performance at 30 °C but decreased sharply by 4-fold when operating temperature was raised to 50 °C. The optimum reactor performance obtained at 40 °C was 1.15 mW/m 2 maximum power density, 89.1% COD removal and a degradation efficiency of 97.10%; at moderately saline (1% w/v) conditions the maximum power density was 1.06 mW/m 2 , 79.1% COD removal and 91.6% degradation efficiency. This work suggests the possible application of MFC technology in the effective treatment of petroleum hydrocarbons contaminated site and refinery effluents

Plastics have become the material of choice in the modern world and its applications in the industrial field are continually increasing. Presently the plastics are manufactured for various uses such as: consumer packaging, wires, pipes, containers, bottles, appliances, electrical/electronic parts, computers and automotive parts. Most of he post consumer, plastic products are discarded and end up as mixed plastic municipal waste. The disposal of his waste has become a major social concern. Mixed plastic waste (MPW) recycling is still very much in its infancy. Approximately 20 million tons of plastic waste is generated in the United States of America, while about 15 million tons is generated throughout the Europe. With existing recycle efforts, only 7% of the MPW are recycled to produce low-grade plastic products such as plastic sacks, pipes, plastic fencing, and garden furniture. The current plastic reclamation technology options are generally grouped into the following four types: (i) Primary: The processing of plastic for use comparable to the original application. (ii) Secondary: The processing of plastics waste into new products with a lower quality level. (iii) Tertiary: The chemical or thermal processing of plastic waste to their basic hydrocarbon feedstock. The resulting raw materials are then reprocessed into plastic material or other products of the oil refining process. (iv) Quaternary: The incineration of plastics waste to recover energy. This paper deals exclusively with tertiary recycling by pyrolysis and catalytic cracking of plastics waste alone and by coprocessing with petroleum residue or heavy oils to fuels and petrochemical feedstock for further processing in existing refinery and petrochemical units.

2018-07-01

Hybrid based bioelectrochemical system (BES) configured with embedded anode and cathode electrodes in soil was tested for the bioelectrochemical degradation of petroleum refinery wastewater (PRW). Four applied potentials were studied to optimize under batch mode operation, among which 2 V resulted in higher COD degradation (69.2%) and power density (725 mW/m 2 ) during 7 days of operation. Further studies with continuous mode of operation at optimized potential (2 V) showed that hydraulic retention time (HRT) of 19 h achieved the highest COD removal (37%) and highest power density (561 mW/m 2 ). BES function with respect to treatment efficiencies of other pollutants of PRW was also identified with respect to oil and grease (batch mode, 91%; continuous mode, 34%), total dissolved salts (batch mode, 53%; continuous mode, 24%) and sulfates (batch mode, 59%; continuous mode, 42%). Soil microenvironment in association with BES forms complex processes, providing suitable conditions for efficient treatment of PRW. Copyright © 2018 Elsevier Ltd. All rights reserved.

White, R.

1998-01-01

The environmental impacts of fuel emissions were discussed. Emissions from petroleum fuels are the largest contributor to a wide range of environmental problems including damage to the ozone layer and risks to human health. Forecasts indicate that future demand for fossil fuels for energy will continue to grow. The transportation sector is the largest single source of air emissions in Canada. The environmental requirements for all fuels will become progressively more stringent. The pollutants of primary concern include toxics, nitrogen oxides, volatile organic compounds, carbon monoxide, sulphur dioxide, and particulates. The U.S. auto-oil research program has conducted considerable research to understand the impact of fuel parameters of vehicle tailpipe emissions. In Canada, lead was removed from Canadian gas a decade ago. Since January 1998, low sulphur diesel (less than 500 ppm) is required for on-road use. Regulations have also been passed to reduce the level of benzene in gasoline to less than one per cent by mid-1999. It will be necessary to manage our fossil fuels to minimize the environmental impacts from combustion. In the longer term, it will be necessary to minimize fossil fuel use through conservation and shift to less polluting fuels

Nowadays a great effort has been spent by companies to improve their logistics in terms of programming of events that affect production and distribution of products. In this case, simulation can be a valuable tool for evaluating different behaviors. The objective of this work is to build a discrete event simulation model for scheduling of operational activities in complexes containing one harbor and two refineries interconnected by a pipeline infrastructure. The model was developed in Arena package, based on three sub-models that control pier allocation, loading of tanks, and transfers to refineries through pipelines. Preliminary results obtained for a given control policy, show that profit can be calculated by taking into account many parameters such as oil costs on ships, pier using, over-stay of ships and interface costs. Such problem has already been considered in the literature but using different strategies. All these factors should be considered in a real-world operation where decision making tools are necessary to obtain high returns. (author)

2015-04-01

Full Text Available Leaded gasoline in Taiwan was gradually phased out from 1983 to 2000. However, it is unclear whether unleaded gasoline still contributes to atmospheric lead (Pb exposure in urban areas. In this study, Pb isotopic compositions of unleaded gasolines, with octane numbers of 92, 95, 98, and diesel from two local suppliers in Taipei were determined by multi-collector inductively coupled plasma mass spectrometry with a two-sigma uncertainty of ± 0.02 %. Lead isotopic ratios of vehicle exhaust (208Pb/207Pb: 2.427, 206Pb/207Pb: 1.148, as estimated from petroleum fuels overlap with the reported aerosol data. This agreement indicates that local unleaded petroleum fuels, containing 10–45 ng·Pb·g−1, are merely one contributor among various sources to urban aerosol Pb. Additionally, the distinction between the products of the two companies is statistically significant in their individual 208Pb/206Pb ratios (p-value < 0.001, t test. Lead isotopic characterization appears to be applicable as a “fingerprinting” tool for tracing the sources of Pb pollution.

A recent National Petroleum Council study identified the environmental costs facing the refining industry from 1995 through 2010. Four broad areas were identified: air pollution control, wastewater treatment, solid and hazardous waste treatment, and occupational health and safety. This paper will present the technical issues and engineering information required to produce an estimate of cost impact. For each of the four areas of impact, the kinds of information required of the refinery manager in order to build an estimate will be tabulated and discussed. For air pollution control, issues will include size and type of unit, product mix of output, and the impact of facility location relative to non-attainment issues. For wastewater, issues will include stormwater segregation, benzene NESHAP, and other treatment system requirements. For hazardous waste treatment, issues will include groundwater protection and leak detection and contaminated soil segregation. For occupational health and safety, issues will include process changes required and worker training required. For all issues, the major dollar factors will be identified as a function of the technical data available. The refinery costs in each areas were estimated for seven groups of refinery sizes. The presentation will conclude with tabulation of cost estimates for each area of investigation and each refinery group. The total costs for each refinery group over the fifteen-year period will also be presented

PERFORMANCE, EMISSION, AND COMBUSTION CHARACTERISTICS OF A CI ENGINE USING LIQUID PETROLEUM GAS AND NEEM OIL IN DUAL FUEL MODE

Directory of Open Access Journals (Sweden)

2010-01-01

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 characteristics of the waste water generated by the petroleum refineries are related to the type and amount of processed oil, to the nature and the efficiency of the refining operation. The effluents are composed basically of oily waters, originating from of the contact with the oil. Among them, the current of sour water is one of the most preoccupying due to its composition: sulfide, ammonia, mercaptans, phenol, dissolved oil, basic pH, dissolved organic carbon (DOC) and chemical oxygen demand (COD) high. The aim of this work was to evaluate the advanced oxidation processes to degrade sour water (UV radiation, H{sub 2}O{sub 2} and H{sub 2}O{sub 2}/UV, photocatalysis, Fenton and photo-Fenton). All process, except Fenton and photo-Fenton, did not supply satisfactory results, reducing 25% of initial DOC, which it is of 450 mg/L. The results using the Fenton process reached removal of 50% of the initial COD, and when photo- Fenton process obtaining removal of 90%. The processes Fenton and photo-Fenton were shown capable to degrade this kind of waste water, minimizing the environmental problems and corrosion, operating as a pre-treatment for the biological system, or acting alone to degrade the organic matter contained, seeking the water reuse. The effluent used in this work came from Duque de Caxias Refinery (Reduc)/PETROBRAS. (author)

Reforming petroleum-based fuels for fuel cell vehicles : composition-performance relationships

Onboard reforming of petroleum-based fuels, such as gasoline, may help ease the introduction of fuel cell vehicles to the marketplace. Although gasoline can be reformed, it is optimized to meet the demands of ICEs. This optimization includes blending to increase the octane number and addition of oxygenates and detergents to control emissions. The requirements for a fuel for onboard reforming to hydrogen are quite different than those for combustion. Factors such as octane number and flame speed are not important; however, factors such as hydrogen density, catalyst-fuel interactions, and possible catalyst poisoning become paramount. In order to identify what factors are important in a hydrocarbon fuel for reforming to hydrogen and what factors are detrimental, we have begun a program to test various components of gasoline and blends of components under autothermal reforming conditions. The results indicate that fuel composition can have a large effect on reforming behavior. Components which may be beneficial for ICEs for their octane enhancing value were detrimental to reforming. Fuels with high aromatic and naphthenic content were more difficult to reform. Aromatics were also found to have an impact on the kinetics for reforming of paraffins. The effects of sulfur impurities were dependent on the catalyst. Sulfur was detrimental for Ni, Co, and Ru catalysts. Sulfur was beneficial for reforming with Pt catalysts, however, the effect was dependent on the sulfur concentration

An oil refinery normally uses large quantities of water, for cooling and other process purpose. This water is treated from contaminants and finally returned to a lake or sea, outside the refinery. Amerya Petroleum Refining Company (APRC) uses conventional and special treatment methods for wastewater to remove all pollutants and to reduce the oil content in refinery final effluent water to a limit of 10 ppm , as the maximum permissible limit for environmental protection as designated by the Egyptian Act No.4 for the year 1994 . About 80% of oil in wastewater is separated by API (American Petroleum Institute) separator method and returned to refinery. Small oil droplets, emulsion and suspended matter escaped from API separator but were removed successfully in the dissolved air flotation (DAF) with chemical additives as the secondary treatment stage for wastewater. The flotation method with chemical additives and filtration were used to reduce the suspended solids and oil content to permissible levels (10 ppm) Furthermore, biological treatment unit was constructed to remove the dissolved oxygen consuming contaminates, e.g. phenolic compounds and traces of hydrocarbon derivatives. It was found that the BOD and COD of the effluent were reduced, and 100% removal of the trace amount of phenol was achieved in effluent

The aim of the study was to investigate petroleum waste remediation and toxicity reduction by five bacterial strains: Ralstonia picketti SRS (BP-20), Alcaligenes piechaudii SRS (CZOR L-1B), Bacillus subtilis (I'-1a), Bacillus sp. (T-1), and Bacillus sp. (T'-1), previously isolated from petroleum-contaminated soils. Petroleum hydrocarbons were significantly degraded (91%) by the mixed bacterial cultures in 30 days (reaching up to 29% in the first 72 h). Similarly, the toxicity of the biodegraded petroleum waste decreased 3-fold after 30 days. This work shows the influence of bacteria on hydrocarbon degradation and associated toxicity, and its dependence on the specific microorganisms present. The ability of these mixed cultures to degrade hydrocarbons and reduce toxicity makes them candidates for environmental restoration applications at other hydrocarbon-contaminated environments.

Existing NO x technologies implemented by the Mobil Torrance refinery have been reviewed. Technologies utilized are Lo-NO x burners, Ultra-Lo-NO x burners and selective catalytic reduction in boilers and process heaters, as well as selective non-catalytic reduction in fluid catalytic cracker/CO boiler applications. With the implementation of the Regional Clean Air Incentives Market (RECLAIM), research at Mobil is directed towards reducing operational costs and improving efficiency in selective catalytic reduction with high and low temperature catalysts. Research is also directed at improved selective non-catalytic reduction efficiency in CO boiler applications and at further NO x reduction in fluid catalytic cracker regenerator offgases. The implementation of proven and enhanced technology is expected to reduce refinery NO x emissions from 1734 metric tons per yr to 487 metric tons per yr by the year 2003. 4 refs., 7 figs

The US Department of Energy's Office of Transportation Technologies, DOE's National Renewable Energy Laboratory, the US Department of Agriculture's Office of Energy, and Ecobalance are carrying out a comprehensive Life-Cycle Assessment of soy-based diesel fuel (biodiesel) to quantify the environmental aspects of the cradle-to-grave production and use of biodiesel. The purpose of the project is to produce an analytical tool and database for use by industry and government decision makers involved in alternative fuel use and production. The study also includes a parallel effort to develop a life-cycle model for petroleum diesel fuel. The two models are used to compare the life-cycle energy and environmental implications of petroleum diesel and biodiesel derived from soybean. Several scenarios are studied, analyzing the influence of transportation distances, agricultural practice and allocation rules used. The project also includes effort to integrate spatial data into the inventory analysis and probabilistic uncertainty considerations into the impact assessment stage. Traditional life-cycle inventory analysis includes an aggregation process that eliminates spatial, temporal, and threshold information. This project will demonstrate an approach to life-cycle inventory analysis that retains spatial data for use in impact assessment. Explicit probabilistic treatment of uncertainty in impact assessment will take account of scientific uncertainties, and will attempt to identify the level of spatial detail that most efficiently reduces impact assessment uncertainties

Nilsson, Kristina; Zetterberg, Lars; Aahman, Markus

2005-02-01

On 1 January 2005, the European Union Emission Trading Scheme (EU ETS) was launched. The launch has been preceded by an allocation process in each of the Member States. The main objective of this study was to analyse the allocation in relation to CO 2 efficiency for the mineral oil refining sector. A CO 2 intensity index for mineral oil refineries has been defined and calculated for the refineries within the EU15 and Norway. The IVL CO 2 intensity index is based both on the Solomon Energy Intensity Index (EII), an assumed fuel mix, and process-specific emissions. Due to uncertainties in input data, the determined values for the individual refineries are quite uncertain. However, the regional values can be used to identify trends. It was concluded that there are substantial differences in the CO 2 intensity between refineries within different regions/countries in the EU and these differences have not been considered in the allocation process. Only a few countries have mentioned energy efficiency or reduction potential due to CO 2 intensity of fuels used. Only one country (Denmark) has explicitly given a benchmark that will be used for allocation to new mineral oil refineries. The allocation has generally been based on historic emissions, which will result in refineries with historically higher emissions being allocated larger amounts than refineries with historically lower emissions. This might be favourable for refineries that recently have performed emission-reducing measures but might be less favourable for refineries that during a long time period have implemented emission-reducing measures

PAH concentrations (15 compounds) in settling particulate matter (SPM) collected in the waters outside a petroleum refinery on the Swedish Baltic coast, and in samples of particulate and dissolved fractions in the wastewater from the refinery were determined. SPM concentrations varied between 550 and 4250 ng x gdw -1 and the corresponding calculated fluxes varied between 0.1 and 3.7 ng x cm -2 x day -1 . Both concentrations and fluxes did not differ significantly from background coastal or offshore locations in the Baltic. PAH profiles of the SPM samples were compared with the wastewater samples and SPM samples from background areas in the Baltic, using pattern recognition techniques. This analysis showed that the SPM samples from the petroleum refinery displayed a PAH composition similar to that found in background reference sites in the Baltic, and that the SPM samples could not be connected to the wastewater samples from the refinery. This indicates that Nynas AB is not a significant source of PAHs to the waters in its immediate surroundings, i.e. the waters in the Nynashamn area, and/or that the hydraulic residence time of the water outside the refinery is low. A budget calculation showed that the wastewater outlet from Nynas AB is only a minor contributor of the PAH load to the waters outside the refinery. (Author)

Future fuels: Canada's coast-to-coast network of refineries is emerging from a $3-billion-plus spending binge to take the lead in producing low sulphur gasoline

International Nuclear Information System (INIS)

Lunan, D.

2004-01-01

A series of investments to convert Canada's 22 operating refineries to produce low-sulphur gasoline are discussed. The investment involves more than $3-billion that will transform Canada's portfolio of aging refineries into one of the most efficient in the western world, and in the process reduce sulphur content in Canadian gasoline to 30 ppm. In some cases the refitting will be completed years ahead of the required 2005 deadline. Total refining capacity in Canada is about 2.5 million barrels per day of crude oil, which includes 580,000 barrels per day of capacity that is dedicated to upgrading bitumen into synthetic crude oil. The initiative to update the refineries was led by Irving Oil, which launched a one billion dollar refit of its 250,000 barrels per day Saint John refinery in the year 2000. Irving Oil's efforts were driven by the company's marketing program in the United States where regional fuel quality standards are higher than national standards either in Canada or the United States. Shell Canada and Imperial Oil are also on track to meet the 30 ppm sulphur level ahead of schedule. For example, Shell Canada is cooperating with Suncor Energy Products in the construction of a hydrotreater at Suncor's Sarnia refinery which will be used to reduce sulphur content of diesel from both the Shell and Suncor refineries, while Imperial Oil is investing over $520 million to refit its refineries in Alberta, Ontario and Nova Scotia. Petro-Canada too, has embarked on a $450 million capital program late in 2003 to introduce low sulphur gasoline; this was in addition to the $1.2 billion program to integrate its bitumen production, upgrading and refining operations. Ultramar launched its $300 million desulphurization program in late 2002; the project is now nearing completion. Refit of Ultramar's Jean Gaulin refinery on Quebec's South Shore will also include a 30,000 barrels per day continuous regeneration platformer to provide a second hydrogen source for the

DGMK research project 583-1 investigates the composition of sulfur-free Diesel fuels as a supplement to DGMK report 583 published in 2002, which reports the composition of Diesel fuels with a sulfur content of max. 350 mg/kg. Thereby the effect of desulfurisation on the composition of Diesel fuels was determined. In summer 2003 fuels from German refineries were sampled and examined. In contrast to the first survey, the number of tests was reduced significantly. Only those parameters were considered that were likely to have changed due to the modified refining processes. Since sulfur-free products have to this extent been investigated for the first time, the results will give a significant contribution to questions regarding application techniques and ecology.

Use of absorption spectroscopy for refined petroleum product discrimination

Science.gov (United States)

Short, Michael

1991-07-01

On-line discrimination between arbitrary petroleum products is necessary for optimal control of petroleum refinery and pipeline operation and process control involving petroleum distillates. There are a number of techniques by which petroleum products can be distinguished from one another. Among these, optical measurements offer fast, non-intrusive, real-time characterization. The application examined here involves optically monitoring the interface between dissimilar batches of fluids in a gasoline pipeline. After examination of near- infrared and mid-infrared absorption spectroscopy and Raman spectroscopy, Fourier transform mid-infrared (FTIR) spectroscopy was chosen as the best candidate for implementation. On- line FTIR data is presented, verifying the applicability of the technique for batch interface detection.

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.

Pursuing the pre-combustion CCS route in oil refineries – The impact on fired heaters

2013-01-01

Highlights: ► The aim is to approach Carbon Capture and Storage (CCS) to refinery fired heaters. ► An identical simplified burner configuration is applied where refinery fuel is replaced with hydrogen. ► Initial simulations indicate that hydrogen replacement do not alter heater operation in a negative way. ► Despite the higher flame temperature in the hydrogen case, the NO x emissions are not higher. ► The prompt-NO mechanism contributes significantly in the refinery fuel case. -- Abstract: The work presented in this paper investigates the effect of replacing refinery fuel gas in the radiant section burners of a fired heater with hydrogen. The aim is to approach pre-combustion CCS to refinery fired heaters by identifying the impact on heat-, flow- and radiation distribution in the lower radiant section of the fired heater when simply switching refinery gas with hydrogen at equivalent power using the same burner geometrics. Additionally the formation of NO x is considered. The investigations are performed using a conventional Reynolds Average Navier Stokes (RANS), Computational Fluid Dynamics (CFD) approach using detailed reaction kinetics consisting of 325 elementary reactions and 53 species. Simplified and generalized furnace and burner geometries are used in the present work. The results show that approximately the same average wall heat flux density is achieved when the refinery fuel is replaced by hydrogen. However, the distribution of heat on the inner surfaces changes. The hydrogen case has, as expected, a higher flame temperature than the base case, nevertheless, the nitric oxide (NO x ) emissions are comparable to base case emissions. Several indications point in the direction of a significant contribution to the base case emissions from the less temperature dependent prompt-NO mechanism, which obviously is not contributing to the hydrogen case emissions.

The first oil refinery in the Kyrgyz Republic was opened on 5 October 1996 in Jalalabad in a ceremony attended by the President of the Central Asian country, Askar Akaev. The 10,000 barrels of oil per day (bopd) modular refinery has been financed by the Canadian oil junior, Kyrgoil Corporation, which has also formed a joint venture with the national oil company, Kyrgyzneft, to redevelop where viable the 628 underperforming oil wells in the Kyrgyz Republic sector of the Fergana Basin. The opening is the first significant milestone in a programme initiated by Akaev to develop the oil production industry in the Kyrgyz Republic. Currently the country imports more than 50,000 barrels of oil equivalent per day, mostly from Kazakhstan. In the year ending March 1996, 110 million was spent on imports of fuel products, an amount that exceeds the trade deficit over the same period. Built in only eight months, the Pound 12 million refinery will gradually be brought to full capacity. By January, it is expected that more than 5,000 barrels of gasoline, diesel and fuel oil will be produced every day. Although there is some crude oil in storage, the ramping of production is tied into the programme of workovers of the existing wells. There are no current plans to import crude, although most of the infrastructure is in place should it become necessary. (author)

Borowski, C.J.; Swett, G.H.

1996-01-01

The historic relationship between many petroleum refineries and vendors was adversarial. However, during the past 10 years, many industrial firms have found that working together with vendors is critical to reducing costs and improving quality--the two key elements required to maintain a competitive position. As refiners have begun working with their vendors more like partners, numerous benefits have accrued to the refining industry. This paper analyzes how the refiner-vendor relationship has changed. Specifically, the authors address the following issues: the competitive threat that has forced a different approach to contracting services and goods; how right-sizing and capacity creep have contributed to the need to re-examine historic practices; key elements in a successful refinery/vendor relationship; how does it work in real life; and implementing a partnering program

Evaluation the Phytoremediation of Oil-contaminated Soils Around Isfahan Oil Refinery

Full Text Available Petroleum compounds are pollutants that most commonly occur in soils around oil refineries and that often find their ways into groundwater resources. Phytoremediation is a cost-effective alternative to physicochemical methods for oil-contaminated soil remediation, where feasible. In this study, a greenhouse experiment was conducted to evaluate the phytoremediation of oil-contaminated soils around Isfahan Oil Refinery. Four different plants (namely, sorghum, barley, agropyron, and festuca were initially evaluated in terms of their germinability in both contaminated and control (non-contaminated soils. Sorghum and barley (recording the highest germinability values were chosen as the species for use in the phytoremediation experiments. Shoot and root dry weights, total and oil-degrading bacteria counts, microbial activity, and total concentrations of petroleum hydrocarbons (TPHs were determined at harvest 120 days after planting. A significant difference was observed in the bacterial counts (total and oil-degrading bacteria between the planted soils and the control. In contaminated soils, a higher microbial activity was observed in the rhizosphere of the sorghum soil than in that of barley. TPHs concentration decreased by 52%‒64% after 120 days in contaminated soil in which sorghum and barley had been cultivated. This represented an improvement of 30% compared to the contaminated soil without plants. Based on the results obtained, sorghum and barley may be recommended for the removal of petro-contaminants in areas close to Isfahan Oil Refinery. Nevertheless, caution must be taken as such cultivated lands may need to be protected against grazing animals.

Life cycle greenhouse gas emission assessment of major petroleum oil products for transport and household sectors in India

International Nuclear Information System (INIS)

Garg, Amit; Vishwanathan, Saritha; Avashia, Vidhee

2013-01-01

Energy security concerns due to high oil import dependence and climate change concerns due to related greenhouse gas emissions are important policy discussions in India. Could life cycle assessment (LCA) of petroleum oil products provide inputs to crude oil sourcing and domestic oil pricing policies to address the two concerns? This paper presents a baseline study on LCA of petroleum products in India from Well to Storage depending on the oil source, type of refinery, product and the selected destinations. The LCA based GHG emissions are found to be higher by 4–12 per cent than GHG emissions from direct fuel consumption alone for LPG, 7–10 per cent for Gasoline, 3–9 per cent for Diesel and 4–10 per cent for Kerosene based on various supply chain routes supplying oil to six largest cities in India. Overall the energy used in oil exploration, refinery and transportation in the LCA have a share of 72–77 per cent, 11–15 per cent and 6–8 per cent, respectively. The paper proposes imposing a relative carbon cess for various oil products in different Indian cities. States could accommodate this additional carbon cess by reducing their respective state taxes without increasing the final delivery price to the consumers. - Highlights: ► LCA emissions are found to be higher by 4–12 per cent than direct fuel consumption emissions. ► Energy used in oil exploration, refinery and transportation in the LCA have a share of 72–77 per cent, 11–15 per cent and 6–8 per cent, respectively. ► Corresponding GHG emission shares are 60–66 per cent, 23–27 per cent and 5–8 per cent, respectively. ► The source of crude oil matters. E and P energy consumption is found highest for African countries. ► Differential carbon cess could be imposed without changing final delivery price to consumers

Allowance Allocation and CO{sub 2} intensity of the EU15 and Norwegian refineries

Energy Technology Data Exchange (ETDEWEB)

Nilsson, Kristina; Zetterberg, Lars; Aahman, Markus

2005-02-01

On 1 January 2005, the European Union Emission Trading Scheme (EU ETS) was launched. The launch has been preceded by an allocation process in each of the Member States. The main objective of this study was to analyse the allocation in relation to CO{sub 2} efficiency for the mineral oil refining sector. A CO{sub 2} intensity index for mineral oil refineries has been defined and calculated for the refineries within the EU15 and Norway. The IVL CO{sub 2} intensity index is based both on the Solomon Energy Intensity Index (EII), an assumed fuel mix, and process-specific emissions. Due to uncertainties in input data, the determined values for the individual refineries are quite uncertain. However, the regional values can be used to identify trends. It was concluded that there are substantial differences in the CO{sub 2} intensity between refineries within different regions/countries in the EU and these differences have not been considered in the allocation process. Only a few countries have mentioned energy efficiency or reduction potential due to CO{sub 2} intensity of fuels used. Only one country (Denmark) has explicitly given a benchmark that will be used for allocation to new mineral oil refineries. The allocation has generally been based on historic emissions, which will result in refineries with historically higher emissions being allocated larger amounts than refineries with historically lower emissions. This might be favourable for refineries that recently have performed emission-reducing measures but might be less favourable for refineries that during a long time period have implemented emission-reducing measures.

2013-01-01

In this study, a novel suspended ceramsite was prepared, which has high strength, optimum density (close to water), and high porosity. The ceramsite was used to feed a moving-bed biofilm reactor (MBBR) system with an anaerobic-aerobic (A/O) arrangement to treat petroleum refinery wastewater for simultaneous removal of chemical oxygen demand (COD) and ammonium. The hydraulic retention time (HRT) of the anaerobic-aerobic MBBR system was varied from 72 to 18 h. The anaerobic-aerobic system had a strong tolerance to shock loading. Compared with the professional emission standard of China, the effluent concentrations of COD and NH3-N in the system could satisfy grade I at HRTs of 72 and 36 h, and grade II at HRT of 18 h. The average sludge yield of the anaerobic reactor was estimated to be 0.0575 g suspended solid/g CODremoved. This work demonstrated that the anaerobic-aerobic MBBR system using the suspended ceramsite as bio-carrier could be applied to achieving high wastewater treatment efficiency.

A DOE/PETC funded study was conducted to examine the use of a liquid phase mixed alcohol synthesis (LPMAS) plant to produce gasoline blending ethers. The LPMAS plant was integrated into three utilization scenarios: a coal fed IGCC power plant, a petroleum refinery using coke as a gasification feedstock, and a standalone natural gas fed partial oxidation plant. The objective of the study was to establish targets for the development of catalysts for the LPMAS reaction. In the IGCC scenario, syngas conversions need only be moderate because unconverted syngas is utilized by the combined cycle system. A once through LPMAS plant achieving syngas conversions in the range of 38--49% was found to be suitable. At a gas hourly space velocity of 5,000 sL/Kg-hr and a methanol:isobutanol selectivity ratio of 1.03, the target catalyst productivity ranges from 370 to 460 g iBuOH/Kg-hr. In the petroleum refinery scenario, high conversions ({approximately}95%) are required to avoid overloading the refinery fuel system with low Btu content unconverted syngas. To achieve these high conversions with the low H{sub 2}/CO ratio syngas, a recycle system was required (because of the limit imposed by methanol equilibrium), steam was injected into the LPMAS reactor, and CO{sub 2} was removed from the recycle loop. At the most economical recycle ratio, the target catalyst productivity is 265 g iBuOH/Kg-hr. In the standalone LPMAS scenario, essentially complete conversions are required to achieve a fuel balanced plant. At the most economical recycle ratio, the target catalyst productivity is 285 g iBuOH/Kg-hr. The economics of this scenario are highly dependent on the cost of the natural gas feedstock and the location of the plant. For all three case scenarios, the economics of a LPMAS plant is marginal at current ether market prices. Large improvements over demonstrated catalyst productivity and alcohol selectivity are required.

Nowadays the existence of energy sources of oil and was limited. Therefore, it was important to searching for new innovations of renewable energy sources by utilizing the waste into a source of energy. On the other hand, the process of extractable petroleum hydrocarbons biodegradation generated sludge that had calorific value and untapped. Because of the need for alternative sources of energy innovation with the concept of zero waste and the fuel potential from extractable petroleum hydrocarbons biodegradation waste, so it was necessary to study the use of extractable petroleum hydrocarbons biodegradation waste as the main material for making solid fuel. In addition, sawdust is a waste that had a great quantities and also had a high calorific value to be mixed with extractable petroleum hydrocarbons biodegradation waste. The purpose of this study was to determine the characteristics of the extractable petroleum hydrocarbons biodegradation waste and to determine the potential and a combination of a mixture of extractable petroleum hydrocarbons biodegradation waste and sawdust which has the best calorific value. The variables of this study was the composition of the waste and sawdust as follows 1:1; 1:3; and 3:1 (mass of sawdust : mass of waste) and time of sawdust carbonization was 10, 15 and 20 minutes. Sawdust was carbonized to get the high heating value. The characteristic of main material and fuel analysis performed with proximate analysis. While the calorific value analysis was performed with a bomb calorimeter. From the research, it was known that extractable petroleum hydrocarbons biodegradation waste had a moisture content of 3.06%; volatile matter 19.98%; ash content of 0.56%; fixed carbon content of 76.4% and a calorific value of 717 cal/gram. And a mixture that had the highest calorific value (4286.5 cal/gram) achieved in comparison sawdust : waste (3:1) by carbonization of sawdust for 20 minutes.

An all-glass heated inlet system has been interfaced to a dual-trap Fourier transform ion cyclotron resonance (FT-ICR) mass spectrometer. The inlet vaporizes a mixture of species of widely different boiling points, and the interface maintains a large (factor of 10(10)) pressure gradient between the inlet and the mass spectrometer, making possible the analysis of petroleum distillates and refinery streams at very high mass resolution. Ions generated by low-energy electron ionization in the source trap of the spectrometer are transferred to the analyzer trap, where the pressure is at least 2 orders of magnitude lower. Singly-charged ions from a mass window of ∼20 u are isolated by stored-waveform radial ejection, to reduce space charge and increase digital resolution:  routine mass resolving power >200 000 (based on magnitude-mode peak full width at half-height) is thereby achieved throughout the full mass window. The mass window may be incremented stepwise to cover the full mass range of several hundred units. The FT-ICR mass spectrum of a gas oil aromatic neutral fraction contained peaks resulting from the resolution of ions having 358 distinct formulas over a mass range of ∼42 u. C(3)/SH(4), (13)C/CH, (13)CH/N, CH(2)/N, and other mass doublets were baseline-resolved, yielding typical mass measurement inaccuracies of ∼1 ppm. For example, (13)C(12)C(17)H(20)S(+) and C(21)H(17)(+), which differ by only 0.0011 u at ∼269 u, were clearly resolved. A 40 000 resolving power low-voltage spectrum of the aromatic neutrals, acquired by use of a Kratos MS-50 double-focusing instrument, was processed with a computer-based deisotoping/formula assignment procedure. The algorithm of the program is outlined and illustrated. Remarkably good agreement exists between the FT-ICR and MS-50 results. However, instrumental rather than indirect resolution of ions clearly enhances analytical accuracy and significantly reduces data-processing time. Thus, we have demonstrated

Overview of Aviation Fuel Markets for Biofuels Stakeholders

Davidson, C.; Newes, E.; Schwab, A.; Vimmerstedt, L.

2014-07-01

This report is for biofuels stakeholders interested the U.S. aviation fuel market. Jet fuel production represents about 10% of U.S. petroleum refinery production. Exxon Mobil, Chevron, and BP top producers, and Texas, Louisiana, and California are top producing states. Distribution of fuel primarily involves transport from the Gulf Coast to other regions. Fuel is transported via pipeline (60%), barges on inland waterways (30%), tanker truck (5%), and rail (5%). Airport fuel supply chain organization and fuel sourcing may involve oil companies, airlines, airline consortia, airport owners and operators, and airport service companies. Most fuel is used for domestic, commercial, civilian flights. Energy efficiency has substantially improved due to aircraft fleet upgrades and advanced flight logistic improvements. Jet fuel prices generally track prices of crude oil and other refined petroleum products, whose prices are more volatile than crude oil price. The single largest expense for airlines is jet fuel, so its prices and persistent price volatility impact industry finances. Airlines use various strategies to manage aviation fuel price uncertainty. The aviation industry has established goals to mitigate its greenhouse gas emissions, and initial estimates of biojet life cycle greenhouse gas emissions exist. Biojet fuels from Fischer-Tropsch and hydroprocessed esters and fatty acids processes have ASTM standards. The commercial aviation industry and the U.S. Department of Defense have used aviation biofuels. Additional research is needed to assess the environmental, economic, and financial potential of biojet to reduce greenhouse gas emissions and mitigate long-term upward price trends, fuel price volatility, or both.

The increase in production of heavier oils and the recent changes in the demand for petroleum derivatives requires modifications in refining schemes of Brazilian refineries, which were originally projected for processing light oils and production of mainly gasoline by fluid catalytic cracking units. This is necessary because forecasts indicate a larger increase in demand for diesel oil instead of gasoline. These same forecasts reveal an expressive reduction in the demand for fuel oil, which still is produced in large amounts in Brazilian refineries due to the quality of the oils from local fields that are processed. The current challenge for the local oil industry is to adapt the present refineries to produce more valuable derivatives from heavy oils. For this purpose, PETROBRAS is investing in the construction of conversion units with technology for processing heavier feeds, especially in the Delayed Coking process. This work has as an objective to identify the importance of the delayed coke units in the current scenario of the oil industry, highlighting the main investments in construction of new units and evaluating the impact of the existing units on the market for petroleum derivatives.

ConocoPhillips, in conjunction with Nexant Inc., Penn State University, and Cummins Engine Co., joined with the U.S. Department of Energy (DOE) National Energy Technology Laboratory (NETL) in a cooperative agreement to perform a comprehensive study of new ultra clean fuels (UCFs) produced from remote sources of natural gas. The project study consists of three primary tasks: an environmental Life Cycle Assessment (LCA), a Market Study, and a series of Engine Tests to evaluate the potential markets for Ultra Clean Fuels. The overall objective of DOE's Ultra Clean Transportation Fuels Initiative is to develop and deploy technologies that will produce ultra-clean burning transportation fuels for the 21st century from both petroleum and non-petroleum resources. These fuels will: (1) Enable vehicles to comply with future emission requirements; (2) Be compatible with the existing liquid fuels infrastructure; (3) Enable vehicle efficiencies to be significantly increased, with concomitantly reduced CO{sub 2} emissions; (4) Be obtainable from a fossil resource, alone or in combination with other hydrocarbon materials such as refinery wastes, municipal wastes, biomass, and coal; and (5) Be competitive with current petroleum fuels. The objectives of the ConocoPhillips Ultra Clean Fuels Project are to perform a comprehensive life cycle analysis and to conduct a market study on ultra clean fuels of commercial interest produced from natural gas, and, in addition, perform engine tests for Fisher-Tropsch diesel and methanol in neat, blended or special formulations to obtain data on emissions. This resulting data will be used to optimize fuel compositions and engine operation in order to minimize the release of atmospheric pollutants resulting from the fuel combustion. Development and testing of both direct and indirect methanol fuel cells was to be conducted and the optimum properties of a suitable fuel-grade methanol was to be defined. The results of the study are also

Samples of sour condensate generated from the continuous processing of both crude shale oil and petroleum crude were collected and extracted with methylene chloride. The extracts were analyzed using capillary-column gas chromatography/mass spectrometry at Argonne National Laboratory and Radian Corporation. Qualitatively, the predominant types of organic compounds present in the shale-oil sour condensate were pyridines and anilines; semiquantitatively, these compounds were present at a concentration of 5.7 ppM, or about 78% of the total concentration of components detected. In contrast, straight-chain alkanes were the predominant types of compounds found in the sour condensate produced during isocracking of conventional crude oil. The approximate concentration of straight-chain alkanes, 8.3 ppM, and of other branched and/or unsaturated hydrocarbons, 6.8 ppM, amounted to 88% of the total concentration of components detected in the sour condensate from the petroleum-crude run. Nitrogen compounds in the shale-oil sour condensate may necessitate alterations of the sour water and refinery wastewater-treatment facilities to provide for organics degradation and to accommodate the potentially greater ammonia loadings. This would include use of larger amounts of caustic to enhance ammonia removal by steam stripping. Possible problems associated with biological removal of organic-nitrogen compounds should be investigated in future experimental shale-oil refining runs.

The use of near infrared (NIR) spectroscopy combined with chemometric methods have been widely used in petroleum and petrochemical industry and provides suitable methods for process control and quality control. The algorithm support vector machines (SVM) has demonstrated to be a powerful chemometric tool for development of classification models due to its ability to nonlinear modeling and with high generalization capability and these characteristics can be especially important for treating near infrared (NIR) spectroscopy data of complex mixtures such as petroleum refinery streams. In this work, a study on the performance of the support vector machines algorithm for classification was carried out, using C-SVC and ν-SVC, applied to near infrared (NIR) spectroscopy data of different types of streams that make up the diesel pool in a petroleum refinery: light gas oil, heavy gas oil, hydrotreated diesel, kerosene, heavy naphtha and external diesel. In addition to these six streams, the diesel final blend produced in the refinery was added to complete the data set. C-SVC and ν-SVC classification models with 2, 4, 6 and 7 classes were developed for comparison between its results and also for comparison with the soft independent modeling of class analogy (SIMCA) models results. It is demonstrated the superior performance of SVC models especially using ν-SVC for development of classification models for 6 and 7 classes leading to an improvement of sensitivity on validation sample sets of 24% and 15%, respectively, when compared to SIMCA models, providing better identification of chemical compositions of different diesel pool refinery streams.

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.

This work addresses the refinery scheduling problem using mathematical programming techniques. The solution adopted was to decompose the entire refinery model into a crude oil scheduling and a product scheduling problem. The envelope for the crude oil scheduling problem is composed of a terminal, a pipeline and the crude area of a refinery, including the crude distillation units. The solution method adopted includes a decomposition technique based on the topology of the system. The envelope for the product scheduling comprises all tanks, process units and products found in a refinery. Once crude scheduling decisions are Also available the product scheduling is solved using a rolling horizon algorithm. All models were tested with real data from PETROBRAS' REFAP refinery, located in Canoas, Southern Brazil. (author)

Coaxial Sensors For Broad-Band Complex Permittivity Measurements of Petroleum Fluids

Energy Technology Data Exchange (ETDEWEB)

Folgeroe, K.

1996-12-31

This doctoral thesis verifies that dielectric spectroscopy and microwave permittivity measurements can be used to characterize petroleum liquids. It concentrates on developing sensors for three potential industrial applications: quality characterization of crude oil and petroleum fractions, monitoring of gas-hydrate formation in water-in-oil emulsions, and determination of water-content in thin liquid layers. The development of a permittivity measurement system for crude oil and petroleum fractions is described. As black oils have low dielectric constant and loss, the system must be very sensitive in order to measure the dielectric spectra and to distinguish oils of different permittivity. Such a system was achieved by combining impedance and scattering parameter measurements with appropriate permittivity calculation methods. The frequency range from 10 kHz to 6 GHz was found convenient for observing the main dispersion of the oils. All the oils had dielectric constants between 2.1 and 2.9 and dielectric loss below 0.01. The oils studied were samples of the feedstock for the cracker and coke processes at a petroleum refinery. This verifies that dielectric spectroscopy is a potential technique for on-line quality monitoring of the feedstock at petroleum refineries. Gas hydrates may cause major problems like clogging of pipelines. Dielectric spectroscopy is proposed as a means of monitoring the formation of gas hydrates in emulsions. It is found that open-ended coaxial probes fulfill the sensitivity requirements for such sensors. 312 refs., 87 figs., 20 tabs.

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

International Nuclear Information System (INIS)

Rowat, M.R.

2006-01-01

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

In recent years concern about the chemical composition of wastewater generated by the oil refining industry has increased, even after its treatment. These wastewaters contain substances that can harm both the entire aquatic ecosystem and the health of any exposed organisms. The aim of this study was to evaluate the genotoxic and mutagenic potentials of the effluent generated by the largest Brazilian petroleum refinery, the effectiveness of the treatments used by the refinery, and whether its effluent can compromise the water quality of the river where it is discarded. Chromosomal aberration and micronucleus assays were performed in Allium cepa and micronucleus test in mammalian cell culture (CHO-K1). The samples were collected in three sites at the refinery: one site on the Jaguari River and two sites on the Atibaia Rivers (upstream and downstream of the discharged effluent), under three different climatic conditions. Tests with A. cepa showed increased frequencies of chromosomal aberrations and micronuclei in meristematic cells for the effluent after physico-chemical treatment, but the samples after treatment biological and stabilization pond presented none of these abnormalities. It was observed that the induced damage in the meristematic cells was not observed in the F 1 cells of A. cepa roots. The micronucleus test performed with mammalian cell culture also indicated that the effluent, after physico-chemical treatment, induced a significant increase in micronucleus frequencies. Plant and hamster cells exposed to the other samples collected inside the refinery and in the Jaguari and Atibaia Rivers did not present evidence of genotoxicity and mutagenicity in the tests performed. This study showed that the effluent treated carried out by the refinery (biological treatment followed by a stabilization pond) proved to be efficient for the removal of the toxic load still present after the physico-chemical treatment, since no change in the quality of the Atibaia

Petroleum industry is one of the largest and fast growing industries due to the ever increasing global energy demands. Petroleum refinery produces huge quantities of wastes like oily sludge, wastewater, volatile organic compounds, waste catalyst, heavy metals, etc., because of its high capacity and continuous operation of many units. Major challenge to this industry is to manage the huge quantities of waste generated from different processes due to the complexity of waste as well as changing stringent environmental regulations. To decrease the energy loss for treatment and also to conserve the energy stored in the chemical bonds of these waste organics, bio-electrochemical system (BES) may be an efficient tool that reduce the economics of waste disposal by transforming the waste into energy pool. The present review discusses about the feasibility of using BES as a potential option for harnessing energy from different waste generated from petroleum refineries. Copyright © 2018.

World petroleum demand is expected to increase from about 15 million barrels to 80 million after the year 2000. The resulting necessity to increase the currently over-extended global refining capacity will put a significant burden on financial resources within the industry. This article examines the developments, after a decade of restructuring, which have led to the present situation of the petroleum industry described as having greatly improved operational conditions but beset by worrisome problems with regard not only to capacity, but also to the costly constraints being imposed by new air pollution regulations, especially those relevant to desulfurization in refinery processes

2012-01-01

The objective of this study was to investigate the application of advanced oxidation processes (AOPs) to the treatment of wastewaters contaminated with hydrocarbon oil. Three different oil-contaminated wastewaters were examined and compared: (i) a 'real' hydrocarbon wastewater collected from an oil refinery (Conoco-Phillips Whitegate refinery, County Cork, Ireland); (ii) a 'real' hydrocarbon wastewater collected from a car-wash facility located at a petroleum filling station; and (iii) a 'synthetic' hydrocarbon wastewater generated by emulsifying diesel oil and water. The AOPs investigated were Fe(2+)/H(2)O(2) (Fenton's reagent), Fe(2+)/H(2)O(2)/UV (Photo-Fenton's reagent) which may be used as an alternative to, or in conjunction with, conventional treatment techniques. Laboratory-scale batch and continuous-flow experiments were undertaken. The photo-Fenton parametric concentrations to maximize COD removal were optimized: pH = 3, H(2)O(2) = 400 mg/L, and Fe(2+) = 40 mg/L. In the case of the oil-refinery wastewater, photo-Fenton treatment achieved approximately 50% COD removal and, when preceded by physicochemical treatment, the percentage removal increased to approximately 75%.

REDUCING POWER PRODUCTION COSTS BY UTILIZING PETROLEUM COKE

Energy Technology Data Exchange (ETDEWEB)

Kevin C. Galbreath; Donald L. Toman; Christopher J. Zygarlicke

1999-09-01

Petroleum coke, a byproduct of the petroleum-refining process, is an attractive primary or supplemental fuel for power production primarily because of a progressive and predictable increase in the production volumes of petroleum coke (1, 2). Petroleum coke is most commonly blended with coal in proportions suitable to meet sulfur emission compliance. Petroleum coke is generally less reactive than coal; therefore, the cofiring of petroleum coke with coal typically improves ignition, flame stability, and carbon loss relative to the combustion of petroleum coke alone. Although petroleum coke is a desirable fuel for producing relatively inexpensive electrical power, concerns about the effects of petroleum coke blending on combustion and pollution control processes exist in the coal-fired utility industry (3). The Energy & Environmental Research Center (EERC) completed a 2-year technical assessment of petroleum coke as a supplemental fuel. A survey questionnaire was sent to seven electric utility companies that are currently cofiring coal and petroleum coke in an effort to solicit specific suggestions on research needs and fuel selections. An example of the letter and survey questionnaire is presented in Appendix A. Interest was expressed by most utilities in evaluating the effects of petroleum coke blending on grindability, combustion reactivity, fouling, slagging, and fly ash emissions control. Unexpectedly, concern over corrosion was not expressed by the utilities contacted. Although all seven utilities responded to the question, only two utilities, Northern States Power Company (NSP) and Ameren, sent fuels to the EERC for evaluation. Both utilities sent subbituminous coals from the Power River Basin and petroleum shot coke samples. Petroleum shot coke is produced unintentionally during operational upsets in the petroleum refining process. This report evaluates the effects of petroleum shot coke blending on grindability, fuel reactivity, fouling/slagging, and

The petroleum sector uses a number of standardized tests to characterize raw materials and products. The development of in-company programs for assurance of measurement quality, the increasing need to demonstrate proficiency by means of certification schemes or by widely accepted metrological practices, have been promoting a more intensive use of certified reference materials, in calibration as well as in validation of measurement methods and also in order to show the qualification of the laboratories. In this paper it is presented the preparation, performed by IPT's Reference Materials Group, of the first set of reference materials specially developed considering the needs of the petroleum community. Briefly, are presented the identification of the demands from the users, selection of matrices, homogeneity tests and stability studies, and the certification of the new reference materials, which are four diesel fuel oils with certified sulfur contents and one material with flash point certified by TAG and Pensky-Martens methods. It is presented a summary of the certification process, performed by means of a combined effort of several professionals that are now working at laboratories of research institutions, refineries and other industries, universities, fuel monitoring facilities and in National Petroleum Agency.

Becoming a refinery leader by changing operations to match new product quality regulations

Mendez, Maryro P. [KBC Advanced Technologies, Surrey (United Kingdom)

2012-07-01

Global environmental concerns have forced the automotive and oil industries to increase efficiency and reduce emissions, which has led to the tightening of fuels specifications around the world. The implementation of ultra-low sulphur transport fuels has become a worldwide trend with growing momentum. Compliance with these standards requires the refiner to make decisions in advance of the implementation date. Therefore, in order to make changes on time, refiners are currently assessing options and changes required to comply with regulations by 2016. Similar regulations have been implemented in Europe already and KBC has the methodology and experience to assess the existing refinery configuration, unit capability and facility infrastructure to provide the basis for decision making. This paper focus on KBC's methodology which looks at the molecular management needed to produce the low levels of sulfur and toxic required in today's refined products. A key element to the study is the use of Petro-SIM for development of a representative detailed non-linear model, of the refinery which has been used to test ideas and configurations and help confirm the Refinery LP development activities. Using a Petro-SIM representation, KBC is able to make an assessment of the impact of imposing Tier 3 gasoline (sulphur to < 10 ppm) on the refinery, examining critical blending constraints, unused stream qualities and quantities and likely type and scale of capital investment that would be required while optimising unit operations and maximising margins. This paper illustrates KBC's current thinking based on studies done to date to review clean fuels and Tier 3 specifications options for specific refinery configurations. (author)

Although the concentration of nitrogen compounds in crude oil is relatively low, they can become more concentrated in petroleum distillates and poison the catalysts used in refining processes. They cause undesirable deposits, color formation and odor in products; they also contribute to air pollution and some are highly carcinogenic. The poisoned catalyst becomes deactivated for hydrodesulfurization and unable to remove sulfur from middle distillates. In order to understand the effect on catalytic processes, it is desirable to identify the nitrogen compounds in various petroleum distillates. This paper compares the nitrogen species profiles in different petroleum distillates using a nitrogen chemiluminescence detector. In addition, four different petroleum distillate samples from different refineries were analyzed to find the variation in their nitrogen profiles. The nitrogen compounds in petroleum distillate samples were identified as anilines, quinolines, indoles, and carbazoles and their alkyl derivatives. Quantitation was carried out against known reference standards. The quantitative data were compared to the total nitrogen content determined by elemental analysis. (orig.)

Samples of soil materials from oil sludge landfarm in Melaka and petroleum sludge ready for disposal were analysed on their potentially toxic elements and compounds and their microbial population. These were compared against uncontaminated soil samples from agricultural plots and fresh crude petroleum samples obtained from an oil refinery in Kerteh, Terengganu. Enumeration and isolation of culturable microbial populations in the above samples were conducted using standard plate counts and screening methods. Populations of microorganisms from uncontaminated soils were tested on its potential to degrade petroleum derived products on contaminated soil samples and crude petroleum samples in a laboratory experiment. Microorganisms with great potential to degrade petroleum sludge will be further screened in further bioremediation studies in the field. (Author)

The sludge comes from a refinery with 220000 barrels of crude per day load, located in the Middle Madgalena River Valley in Colombia. The technological package allows for a) the recovery of the hydrocarbon contained in oily wastes (up to 50%) b) the elimination of the oil contained in solid using a biodegradation process and, c) the availability economically and technically feasible solution to handle oily sludge generated in the refinery. The oily treated in this process come from maintenance of refinery's equipment and also from the physical chemical separation process at the industrial wastewater treatment plant. Oily sludge is a complex system where light and heavy oils, contaminated water and contaminated solids coexist in the form of direct, inverse and multiple emulsions. The comprehensive technological package allows the treatment of oily sludge in a cost effective way. ICP technological package developed includes technologies combining mechanical, thermal, chemical and electrostatic dehydration techniques and stimulated and intensive bioremediation to decontamination of solids saturated with residual oil. This technological package brings a solution to old environmental problem caused by the inappropriate final disposal of oily wastes such as storage in ponds, marshes and open pits: Nowadays wastes generated are treated in a continuous process that is environmentally friendly and economically profitable

Biological treatment of petroleum sludges in liquid/solids contact reactors

Stroo, H F [Remediation Technologies, Inc., Kent, WA (USA)

1989-10-01

Biological treatment of hazardous wastes (bioremediation) is now recognized as an effective and cost-efficient approach for on-site cleanup of petroleum-contaminated soils and sludges. These strategies may require pretreatment of oily sludges produced as refinery wastes. Recent work has shown that liquid/solids contact (LSC) bioreactors are capable of adequate pretreatment at lower cost than competing technologies. Since LSC operations aim to maximize microbial numbers and activity, inexpensive microbiological monitoring can provide rapid feedback on performance. LSC technology represents a method for rapid biological treatment of petroleum sludges in a contained reactor. The technology has proven highly effective for a variety of oil refinery sludges, with degradation rates up to ten times faster than those observed during land treatment. The most promising use of LSC is a pretreatment. Because biological treatment in LSC can degrade and detoxify contaminants rapidly and relatively inexpensively, with little risk of off-site contamination, this technology should be considered by refiners having to close sites or treat current waste-streams. 7 refs., 1 figs., 1 tab.

2013-01-01

The health impacts associated with uncontrolled release of TENORM in products and wastes released in the petroleum industry are of great concern. In this study, evaluation of TENORM in the Tunisian petroleum products and wastes is presented. Fourteen products samples, twelve waste samples and three samples from the surrounding environment were collected from the Tunisian Refinery STIR site and from two onshore production oilfields. The activity concentrations of 232 Th, 226 Ra and 40 K for all samples were determined using gamma-ray spectrometry with High Purity Germanium (HPGe) detector. The activity concentrations of 224 Ra were calculated only for scale samples. The radium equivalent activity, external and internal hazard indices, absorbed doses rates in air and annual effective dose were also estimated. It was noticed that maximum value of Ra eq activity was found to be 398 Bq/kg in scale (w8) collected from an onshore production oilfield which exceeds the maximum Ra eq value of 370 Bq/kg recommended for safe use. All hazard indices indicated that scale samples (w6, w7, w8 and w11) could be a significant waste problem especially sample (w8). In this study, the radium isotopic data were used to provide an estimate of scale samples ages by the use of the 224 Ra/ 228 Ra activity ratio dating method. Ages of collected scales were found to be in the range 0.91–2.4 years. In this work, radioactivity (NORM contamination) in samples collected from the refinery STIR are showed to be insignificant if compared to those from onshore oilfield production sites. - Highlights: ► We followed 232 Th, 226 Ra and 40 K concentrations in Tunisian petroleum products and wastes. ► Radium isotopic data were used to estimate the age of scales deposited in the petroleum production equipments. ► Samples collected from refinery installation did not represent radiological risk. ► Scale samples collected from oil fields installation exceeded UNSCEAR rules.

Environment Canada has developed new regulations for sulphur content in fuels in an effort to align with requirements recently passed by the U.S. Environmental Protection Agency. This report summarizes data regarding sulphur content in liquid fuels for the year 2002. The requirements of the Sulphur in Gasoline Regulation came into effect in 2002, limiting the average sulphur content of gasoline to 150 mg/kg. In January 2005, a 30 mg/kg average limit will come into effect. Also, in July 2002, the Sulphur in Diesel Fuel Regulation stipulated a maximum limit of 500 mg/kg for on-road diesel fuel. The new regulation continues this limit until mid-2006 at which time a 15 mg/kg limit will come into effect for on-road diesel fuel. Nationally, the average sulphur content in gasoline in 2002 was 246 mg/kg, which was 14.3 per cent lower than in 2001. The data covers the period from January 1 to December 31, 2002 and was obtained from petroleum refineries and importing companies that are required to submit quarterly information to the regional office of Environment Canada. Failure to comply results in penalties. The report includes data for aviation turbo fuel, motor gasoline, aviation gasoline, kerosene oil, low-sulphur diesel fuel, diesel fuel, light fuel oil, and heavy fuel oil. 16 tabs., 17 figs., 7 appendices.

Ali, N.A.; El-Tamany, E.H.; El-Emary, M.M.

2011-01-01

The main objective of the present work is to perform a comparative laboratory study using an adsorption technique for oil removal from the waste water drained to sea from refineries, offshore and/or onshore petroleum installations. Different crushed adsorbent materials, namely, cotton fibers, charcoal, petroleum coke, agriculture wastes (such as, rice straws, wheat stems, milled dry leaves and lignin), inorganic adsorbents (such as sand, and bricks) and a marine Product (such as sponge) are included in this study. They were tested for oil recovery from laboratory prepared oily salt water samples. Two different Egyptian crude oils varying in their properties and several refined products (gasoline, kerosene, gas oil, diesel oil, fuel oil, lubricating oil) and skimmed oil were employed. Their adsorptive efficiencies were tested. Good results were obtained with sponge and cotton fibers. The used agricultural wastes show better adsorption compared with coke and inorganic adsorbents.

The waste tail gas fuel emitted from refinery plant in Taiwan e.g. catalytic reforming unit, catalytic cracking unit and residue desulfurization unit, was recovered and reused as a replacement fuel. In this study, it was slowly added to the fuel stream of a heater furnace to replace natural gas for powering a full-scale distillation process. The waste tail gas fuel contained on average 60 mol% of hydrogen. On-site experimental results show that both the flame length and orange-yellowish brightness decrease with increasing proportion of waste gas fuel in the original natural gas fuel. Moreover, the adiabatic flame temperature increases as the content of waste gas fuel is increased in the fuel mixture since waste gas fuel has a higher adiabatic flame temperature than that of natural gas. The complete replacement of natural gas by waste gas fuel for a heater furnace operating at 70% loading (i.e. 3.6 x 10{sup 7} kcal/h of combustion capacity) will save 5.8 x 10{sup 6} m{sup 3} of natural gas consumption, and 3.5 x 10{sup 4} tons (or 53.4%) of CO{sub 2} emission annually. Recovering and reusing the waste tail gas fuel as natural gas replacement will achieve tremendous savings of natural gas usage and effectively lower the emission of carbon dioxide. (author)

Petroleum product scarcity: a review of the supply and distribution of petroleum products in Nigeria

International Nuclear Information System (INIS)

Akpoghomeh, Osi S.; Badejo, Dele

2006-01-01

Nigeria ranks high among the comity of oil producers both at the world level and among the OPEC eleven. It is, therefore, paradoxical that the supply of all petroleum products is erratic and has declined sharply in the recent past. This paper thus reviews the petroleum product supply and distribution systems in the country to ascertain the extent to which the system may have contributed to the present product scarcity in Nigeria and, by extension, identify the causes of the present regime of petroleum product scarcity. The paper observes that the network density and connectivity of petroleum product distribution pipelines are low and both indicators consequently show the inadequacy/deficiency of the network in ensuring an efficient distribution system. The supply mode, on the other hand, has, over the years, demonstrated its inability to guarantee adequate supply due to factors including sabotage, vandalism, banditry and poorly maintained infrastructure. Further, the federal government and the major and independent marketers could not sustain the importation of petroleum products because of the shortfall between the landed cost of imported products and their selling prices in Nigeria, which made the business unprofitable. Finally, the paper examines the withdrawal by the federal government of subsidies on the price of petroleum products consumed locally. All the above factors together occasioned increases in the cost of products. In conclusion, this paper supports the call for the privatization of refineries and the depot/pipeline system as a viable option to end the supply problems. (Author)

Energy demand analysis of Port-Harcourt refinery, Nigeria and its policy implications

International Nuclear Information System (INIS)

Jesuleye, O.A.; Siyanbola, W.O.; Sanni, S.A.; Ilori, M.O.

2007-01-01

This paper analyses energy demand of Port-Harcourt refinery, Nigeria, based on information obtained from its annual publications, backed-up by spot interviews. The analytical approach adopted for the study involves the calculation of energy intensities to determine the refinery's annual energy demand for various energy types considered from 1989 to 2004. The results showed that the actual energy demand per year for processing crude oil into refined products, exceeded, in varying degrees the stipulated refinery standard of 4 barrels of oil equivalent (BOE) per 100 BOE. It varied from 4.28-8.58 BOE per 100 BOE. In terms of energy demand efficiency, this implies very poor performance of the refinery during the 16-year period under investigation. The excess demand which translates to an average daily wastage of about 2005 BOE is estimated to be $56,196 (US Dollars) based on the 2003 OPEC basket price of $28.0213 per barrel. Lack of optimal fuel utilization-mix and non-compliance with the Turn-Around-Maintenance schedules were attributed to the refinery's inefficient energy demand pattern

Petroleum environmental research forum field study on biofilters for control of volatile hydrocarbons

International Nuclear Information System (INIS)

Leson, G.; Smith, B.J.

1997-01-01

A field study on the treatment of volatile petroleum hydrocarbons (PHC) by biofiltration was conducted by the Petroleum Environmental Research Forum (PERF) between 1992 and 1994. Its objective was to assess the technical, regulatory, and economic feasibility of biofiltration for off-gases from petroleum processing and soil remediation equipment. It involved three small-scale biofilters provided by US vendors, treating off-gas from two soil vapor extraction sites and a source of refinery wastewater. Comprehensive monitoring of biofilter operating parameters and performance was conducted. Typically more than 95% of aromatic compounds such as benzene, and odorous reduced sulfur compounds can be removed at residence times of one minute or less, while removal of more than 70% of light aliphatics will require residence times of several minutes, and will thus require correspondingly large filter volumes and higher capital expenditure. The high percentage removal of aromatic hazardous air pollutants (HAP) and odors can generally be accomplished at comparatively short residence times while the need for high-percentage removal, particular of light aliphatics ( 5 ) will generally render biofiltration noncompetitive. Finally, a preliminary economic comparison of biofilters and established control technologies suggested that biofiltration may, for a representative design case involving off-gas from a refinery wastewater treatment operation, offer considerable savings in total cost of air pollution control for petroleum hydrocarbon streams if regulations require the control of aromatic HAP or odors

Oil refining in a CO2 constrained world: Effects of carbon pricing on refineries globally

International Nuclear Information System (INIS)

Abdul-Manan, Amir F.N.; Arfaj, Abdullah; Babiker, Hassan

2017-01-01

Six aggregated refinery linear programming (LP) models were developed to represent actual refineries in North America, Latin America, Europe (including the CIS), Middle East, Asia (excluding China) and China. The models were used to conduct regional comparative assessments and to evaluate the effects of carbon pricing on refinery operations globally. We found that the average refinery energy efficiencies for the regions were estimated to range from 92.2% to 95.2%. The well-to-refinery gate carbon intensities for gasoline, diesel and jet fuels were estimated to be 17.1 (16.4–19.4), 13.3 (12.5–14.2) and 10.1 (9.6–10.8) gCO2eq/MJ, respectively. If refineries are forced to at least meet the 2014 regional volume demands for oil products, pricing CO 2 would not have an impact on either refinery productions, efficiency or emissions. If refineries are allowed to re-optimize production slates to reduce CO 2 emissions, refineries would opt to increase gasoline yield at the expense of diesel. This is counter intuitive since gasoline has a higher carbon intensity than diesel. The refinery bias against dieselization creates a supply preference toward a less efficient transportation end use. Here, we argue that if carbon pricing is not administered properly, this can lead to emissions leakage from refineries to the road transport sector. - Highlights: • Investigate actual refinery productions in 6 regions globally. • Refineries already operate at the most efficient levels. • Complex refineries tolerate higher CO 2 prices better. • Carbon pricing induces bias against dieselization. • Identify potential emissions leakage.

Future demand of petroleum products in India

This paper examines the long-run equilibrium relationship between total petroleum products consumption and economic growth in India for the period 1970-1971 to 2001-2002 using cointegration and error-correction modeling approach. Augmented Dickey-Fuller tests reveal that both the series, after logarithmic transformation, are non-stationary and individually integrated of order one. The empirical results suggest that the series are cointegrated. The 'long-term demand elasticity for petroleum products' has been estimated. Furthermore, as a special case, similar sort of exercise between the consumption of middle-distillates and economic growth in India using annual data for the time span 1974-1975 to 2001-2002 has been carried out, which also confirms the existence of cointegration. In-sample forecasts fitted well against actual numbers. Finally, the paper forecasts total petroleum products and middle-distillates demands till 2011-2012 and provide an idea about the investment required in refinery sector in India till 2011-2012

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.

Marano, J.J.; Rogers, S.; Spath, P.L.; Mann, M.K.

1995-01-01

The US by ratification of the United Nations Framework Convention on Climate Change has pledged to emit no higher levels of greenhouse gases in the year 2000 than it did in 1990. Biomass-derived products have been touted as a possible solution to the potential problem of global warming. However, past studies related to the production of liquid fuels, chemicals, gaseous products, or electricity from biomass, have only considered the economics of producing these commodities. The environmental benefits have not been fully quantified and factored into these estimates until recently. Evaluating the environmental impact of various biomass systems has begun using life-cycle assessment. A refinery Linear Programming model previously developed has been modified to examine the effects of CO 2 -capping on the US refining industry and the transportation sector as a whole. By incorporating the results of a CO 2 emissions inventory into the model, the economic impact of emissions reduction strategies can be estimated. Thus, the degree to which global warming can be solved by supplementing fossil fuels with biomass-derived products can be measured, allowing research and development to be concentrated on the most environmentally and economically attractive technology mix. Biomass gasification to produce four different refinery feedstocks was considered in this analysis. These biomass-derived products include power, fuel gas, hydrogen for refinery processing, and Fischer-Tropsch liquids for upgrading and blending into finished transportation fuels

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

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

2000-08-20

The Advanced Petroleum-Based Fuels-Diesel Emissions Control Program (APBF-DEC) began in February 2000 and is supported by government agencies and industry. The purpose of the APBF-DEC program is to identify and evaluate the optimal combinations of fuels, lubricants, diesel engines, and emission control systems to meet the projected emission standards for the 2000 to 2010 time period. APBF-DEC is an outgrowth of the earlier Diesel Emission Control-Sulfur Effects Program (DECSE), whose objective is to determine the impact of the sulfur levels in fuel on emission control systems that could lower the emissions of NOx and particulate matter (PM) from diesel powered vehicles in the 2002 to 2004 period. Results from the DECSE studies of two emission control technologies-diesel particle filter (DPF) and NOx adsorber-will be used in the APBF-DEC program. These data are expected to provide initial information on emission control technology options and the effects of fuel properties (including additives) on the performance of emission control systems.

Gasification in Petroleum Refinery of 21st Century La gazéification dans la raffinerie du pétrole du XXIe siècle

Full Text Available The worldwide trends in the crude oil supply indicate a continuous increase of the heavy crudes. The increase in the yield of distillation residues is complemented by an increase in their sulfur content. Additional distillates are produced by upgrading the residues. The upgrading step generates final residues, such as visbreaking tar, coke and asphalt which are produced by visbreaking, coking and deasphalting, respectively. The final residues can be converted to usable products such as hydrogen, steam, electricity, ammonia and chemicals. For this purpose, gasification has emerged as the technology of choice because of its superior environmental performance when compared with the competing means for residue utilization. Also, refinery sludges can be cogasified with the final residues and as such, be converted to usable products. If integrated with the petroleum refinery, gasification can diminish any environmental problems associated with residue and sludge disposal. The economic indicators of the refinery can improve as well. The trends in deregulation of the power market enable petroleum refineries to enter this lucrative market either alone or in a partnership with the utilities. The potential of coproduction of chemicals and steam with electricity offers the flexibility to respond to market demands. Gasification technology is commercially proven. Among several types, entrained bed gasifiers are the gasifiers of choice. A number of commercial projects in Europe, Asia and United States use a gasifier employing either a slurry feeding system or a dry feeding system. Les tendances de la production mondiale de pétrole brut indiquent une augmentation continue de la part des bruts lourds. La progression du rendement en résidus de distillation s'accompagne d'une augmentation de la teneur en soufre. Des distillats supplémentaires peuvent être obtenus en traitant les résidus.

Effect of adoption of gas turbine in oil refinery

Energy Technology Data Exchange (ETDEWEB)

Tamai, Hiroto

1988-08-01

With progress in energy saving, and increase in automation in facilities, the dependence on electric power increases relative steam power. Further in order to reduce the production cost, the adoption of gas turbine combined cycle system, mainly aimed at power generation, is considered to be most suitable. This adoption, accompanied with the utilization of refinery offgas, dresults in a reduction in unit power generation cost, by increasing the ratio of domestic power generation. The gas turbine using deethanizing tower offgas as main fuel and butane as auxillary fuel, the combined cycle system, where steam produced from the turbine waste heat boiler drives the existing back pressure turbine, was constituted. The generator is 118 kVA in capacity. Against the maximum power demand being 16,500 kWh in the oil refinery, the obtainment of 11,000 kWh by the gas turbine and 2,500 kWh by the back pressure turbine was assured, with a considerable lowering in power to be purchased.

In this paper a brief description of the main processes present in a modern high capacity refinery is done. The methodology used to evaluate, through exergy analysis, the performance of the refinery's utilities plant since it is responsible for a very considerable amount of the total exergy destruction in a refinery is presented. The utilities plant products: steam, electricity, shaft power and high pressure water had their exergy unit cost determined using exergoeconomic approach. A simple and effective method called condensing to power was used to define the product of the condensers in exergy basis. Using this method it is possible to define the product of the condenser without the use of negentropy concept nor the aggregation of condensers to the steam turbines. By using this new approach, the costs obtained for the plant's products are exactly the same costs obtained when the condenser is aggregated to the steam turbine but with the advantage that the information about the stream between condenser and the steam turbine is not lost and the condenser can be evaluated singly. The analysis shows that the equipment where attention and resources should be focused are the boilers followed by the gas turbine, that together, are responsible for 80% of total exergy destruction in the utilities plant. The total exergy efficiency found for the utilities plant studied is 35% while more than 280 MW of exergy is destroyed in the utilities processes. (author)

In four ratio experiments, natural waters, sampled from the mountain reservoir and the sea water around Dalian city, were mixed with the sewage from petroleum refinery and petroleum exploitation plants. The fluorescence spectra of water samples containing only chromophoric dissolved organic matters(CDOM), samples containing only petroleum, and samples containing a mixture of petroleum and CDOM were analyzed, respectively. The purpose of this analysis is to provide a basis for determining the contribution of petroleum substances and CDOM to the total absorption coefficient of the petroleum-contaminated water by using fluorescence technique. The results showed that firstly, CDOM in seawater had three main fluorescence peaks at Ex: 225-230 nm/Em: 320-330 nm, Ex: 280 nm/Em: 340 nm and Ex: 225-240 nm/Em: 430-470 nm, respectively, and these may arise from the oceanic chlorophyll. CDOM in natural reservoir water had two main fluorescence peaks at EX: 240- 260 nm/Em: 420-450 nm and Ex: 310~350 nm/Em: 420--440 nm, respectively, and these may arise from the terrestrial sources; secondly, the water samples containing only petroleum extracted with n-hexane had one to three fluorescence spectral peaksat Ex: 220-240 nm/Em: 320-340 nm, Ex: 270-290 nm/Em: 310-340 nm and Ex: 220-235 nm/Em: 280-310 nm, respectively, caused by their hydrocarbon component; finally, the water samples containing both petroleum and CDOM showed a very strong fluorescence peak at Ex: 230-250 nm/Em: 320-370 nm, caused by the combined effect of CDOM and petroleum hydrocarbons.

Phenol exposure is one of the hazards in the industrial wastewater treatment basin of any refinery. It additively interacts with hydrogen sulfide emitted from the wastewater basin. Consequently, its concentration should be greatly lower than its threshold limit value. The present study aimed at controlling occupational exposure to phenol in the work environment of wastewater treatment plant in a refinery by reducing phenolic compounds in the industrial wastewater basin. This study was conducted on both laboratory and refinery scales. The first was completed by dividing each wastewater sample from the outlets of different refinery units into three portions; the first was analyzed for phenolic compounds. The second and third were for laboratory scale charcoal and bacterial treatments. The two methods were compared regarding their simplicities, design, and removal efficiencies. Accordingly, bacterial treatment by continuous flow of sewage water containing Pseudomonas Aeruginosa was used for refinery scale treatment. Laboratory scale treatment of phenolic compounds revealed higher removal efficiency of charcoal [100.0(0.0) %] than of bacteria [99.9(0.013) %]. The refinery scale bacterial treatment was [99.8(0.013) %] efficient. Consequently, level of phenol in the work environment after refinery-scale treatment [0.069(0.802) mg/m(3)] was much lower than that before [5.700(26.050) mg/m(3)], with removal efficiency of [99.125(2.335) %]. From the present study, we can conclude that bacterial treatment of phenolic compounds in industrial wastewater of the wastewater treatment plant using continuous flow of sewage water containing Pseudomonas Aeruginosa reduces the workers' exposure to phenol.

This study explores the possibility of using electrocoagulation to remove phenol from oil refinery waste effluent using a cell with horizontally oriented aluminum cathode and a horizontal aluminum screen anode. The removal of phenol was investigated in terms of various parameters namely: pH, operating time, current density, initial phenol concentration and addition of NaCl. Removal of phenol during electrocoagulation was due to combined effect of sweep coagulation and adsorption. The results showed that, at high current density and solution pH 7, remarkable removal of 97% of phenol after 2h can be achieved. The rate of electrocoagulation was observed to increase as the phenol concentration decreases; the maximum removal rate was attained at 30 mg L(-1) phenol concentration. For a given current density using an array of closely packed Al screens as anode was found to be more effective than single screen anode, the percentage phenol removal was found to increase with increasing the number of screens per array. After 2h of electrocoagulation, 94.5% of initial phenol concentration was removed from the petroleum refinery wastewater. Energy consumption and aluminum Electrode consumption were calculated per gram of phenol removed. The present study shows that, electrocoagulation of phenol using aluminum electrodes is a promising process.

Among chemical industries, petroleum refineries have been identified as large emitters of a wide variety of pollutants. Benzene, toluene, ethylbenzene, and xylene (BTEX) form an important group of aromatic volatile organic compounds (VOCs) because of their role in the troposphere chemistry and the risk posed to human health. A very large crude oil refinery of the Baltic States (200,000 bbl/day) is situated in the northern, rural part of Lithuania, 10 km from the town of Mažeikiai (Lithuania). The objectives of this study were: (1) to determine of atmospheric levels of BTEX in the region rural and urban parts at the vicinity of the crude oil refinery; and (2) to investigate the effect of meteorological parameters (wind speed, wind direction, temperature, pressure, humidity) on the concentrations measured. The averaged concentration of benzene varied from 2.12 ppbv in the rural areas to 2.75 ppbv in the urban areas where the traffic was determined to be a dominant source of BTEX emissions. Our study showed that concentration of benzene, as strictly regulated air pollutant by EU Directive 2008/50/EC, did not exceed the limit of 5 ppbv in the region in the vicinity of the crude oil refinery during the investigated period. No significant change in air quality in the vicinity of the oil refinery was discovered, however, an impact of the industry on the background air quality was detected. The T/B ratio (0.50-0.81) that was much lower than 2.0, identified other sources of pollution than traffic.

Tower fouling at petroleum refineries is related to background volatile phosphorus components originating from phosphate ester oil gellants. In an attempt to reduce the cost of unplanned refinery shut downs, the Canadian Association of Petroleum Producers (CAPP) may institute a new specification in July 2006 of 0.5 ppm maximum volatile phosphorus in crude. In concept, volatile phosphorus can be removed from phosphate esters by eliminating volatile components in the original phosphate ester gellant. However, the issue of of whether modified phosphate esters can really reduce refinery tower fouling has been questioned. For that reason, this study focused on water hydrolysis which may occur in a distillation tower, causing localized areas of acidity and causticity. Halogenation reactions could occur in the presence of acid at high temperatures if halogen ions are present. The source of halide ions could be any salts that have not been removed in the de-salters. Full-scale testing at a pilot plant facility was conducted over several days with flowback captured after actual fracturing treatments. Fouling of distillation tower trays was measured along with fouling of the packing material. The study examined how fouling was influenced by changes in operating parameters such as rate, temperature, or pressure during each test. Three full-scale pilot evaluations were conducted using actual flowback fluids from fracturing treatments conducted with 3 different oil gellants: conventional phosphate ester, modified phosphate and phosphonate ester. The comparison of actual tower fouling between these alternative gellants can be used as a guide when choosing oil gellant systems to reduce refinery tower and heat exchanger fouling. It was concluded that phosphonate gellants are hydrolytically stable at higher temperatures and should minimize volatile phosphorus created through the hydrolysis of phosphate esters. However, they are more expensive since they are more complex to create

A Steam Utility Network Model for the Evaluation of Heat Integration Retrofits – A Case Study of an Oil Refinery

2017-12-01

Full Text Available This paper presents a real industrial example in which the steam utility network of a refinery is modelled in order to evaluate potential Heat Integration retrofits proposed for the site. A refinery, typically, has flexibility to optimize the operating strategy for the steam system depending on the operation of the main processes. This paper presents a few examples of Heat Integration retrofit measures from a case study of a large oil refinery. In order to evaluate expected changes in fuel and electricity imports to the refinery after implementation of the proposed retrofits, a steam system model has been developed. The steam system model has been tested and validated with steady state data from three different operating scenarios and can be used to evaluate how changes to steam balances at different pressure levels would affect overall steam balances, generation of shaft power in turbines, and the consumption of fuel gas.

In this study, we evaluated the impacts of producing HOF with a RON of 100, using a range of ethanol blending levels (E10, E25, and E40), vehicle efficiency gains, and HOF market penetration scenarios (3.4% to 70%), on WTW petroleum use and GHG emissions. In particular, we conducted LP modeling of petroleum refineries to examine the impacts of different HOF production scenarios on petroleum refining energy use and GHG emissions. We compared two cases of HOF vehicle fuel economy gains of 5% and 10% in terms of MPGGE to baseline regular gasoline vehicles. We incorporated three key factors in GREET — (1) refining energy intensities of gasoline components for the various ethanol blending options and market shares, (2) vehicle efficiency gains, and (3) upstream energy use and emissions associated with the production of different crude types and ethanol — to compare the WTW GHG emissions of various HOF/vehicle scenarios with the business-as-usual baseline regular gasoline (87 AKI E10) pathway.

Biofuels Fuels Technology Pathway Options for Advanced Drop-in Biofuels Production

Energy Technology Data Exchange (ETDEWEB)

Kevin L Kenney

2011-09-01

Advanced drop-in hydrocarbon biofuels require biofuel alternatives for refinery products other than gasoline. Candidate biofuels must have performance characteristics equivalent to conventional petroleum-based fuels. The technology pathways for biofuel alternatives also must be plausible, sustainable (e.g., positive energy balance, environmentally benign, etc.), and demonstrate a reasonable pathway to economic viability and end-user affordability. Viable biofuels technology pathways must address feedstock production and environmental issues through to the fuel or chemical end products. Potential end products include compatible replacement fuel products (e.g., gasoline, diesel, and JP8 and JP5 jet fuel) and other petroleum products or chemicals typically produced from a barrel of crude. Considering the complexity and technology diversity of a complete biofuels supply chain, no single entity or technology provider is capable of addressing in depth all aspects of any given pathway; however, all the necessary expert entities exist. As such, we propose the assembly of a team capable of conducting an in-depth technology pathway options analysis (including sustainability indicators and complete LCA) to identify and define the domestic biofuel pathways for a Green Fleet. This team is not only capable of conducting in-depth analyses on technology pathways, but collectively they are able to trouble shoot and/or engineer solutions that would give industrial technology providers the highest potential for success. Such a team would provide the greatest possible down-side protection for high-risk advanced drop-in biofuels procurement(s).

Trudelle, F.

2004-01-01

Canada's second largest oil refinery is operated by Ultramar Ltd. in Levis, Quebec. The refinery, which supplies 45 per cent of all Quebec's petroleum, distributes its products to Quebec, Ontario and the Maritime provinces. The refinery currently produces 215,000 barrels per day. Ultramar is a division of Valero, an American firm which has a total refining capacity of 2.4 million barrels per day. A summary of the company's petroleum energy distribution, consumption, and reserves was presented and compared with the national and global position. It was noted that world demand for petroleum products increases yearly by 1 to 1.5 per cent while the demand for automobile fuel in North America increases by 2.5 to 3.5 per cent. In the last 10 years, world demand has increased by more than 22 per cent but refining capacity has only increased by 12 per cent. The average profitability of the refining industry from 1992 to 2002 was approximately 5.5 per cent, which limited investments in new refinery installations. Much of the industry's profits have been utilized to modify installations in order to reduce the sulphur content in gasoline and diesel fuels. Furthermore, the obtention of permits to construct new refining installations has become a major obstacle and the ratification of the Kyoto Protocol may signify a 30 per cent reduction in automotive fuel demand. Given this, there is currently some hesitation and uncertainty by the refining industry to proceed with new major installations. tabs., figs

Production and refining. Increase of Chinese petroleum imports

China produced 156.5 Mt of petroleum in 1996, from which 56 Mt were extracted from the Daqing oil field, exploited since 1960. About 10% of the crude oil comes from offshore fields. Over the 100 Mt refined in 1996, 20 Mt were imported. The Chinese petroleum products demand should increase to 200 Mt/y by the end of the century with respect to 150 Mt/y in 1997. The Dalian refinery, the first Chinese-foreign joint venture, started to work in November 1996 and should reached its full capacity of 100000 b/day in the first quarter of 1997. The Chinese refining activity has now an excess capacity of 206 Mt/y. Several other joint venture projects in petrochemistry are planned in China. Short paper. (J.S.)

Laser-Driven Calorimetry Measurements of Petroleum and Biodiesel Fuels.

Presser, Cary; Nazarian, Ashot; Millo, Amit

2018-02-01

Thermochemical characteristics were determined for several National Institute of Standards and Technology standard-reference-material petroleum and biodiesel fuels, using a novel laser-heating calorimetry technique. Measurements focused on the sample thermal behavior, specific heat release rate, and total specific heat release. The experimental apparatus consists of a copper sphere-shaped reactor mounted within a chamber, along with laser-beam-steering optical components, gas-supply manifold, and a computer-controlled data-acquisition system. At the center of the reactor, liquid sample is injected onto a copper pan substrate that rests and is in contact with a fine-wire thermocouple. A second thermocouple is in contact with the inner reactor sphere surface. The reactor is heated from opposing sides by a continuous-wave, near-infrared laser to achieve nearly uniform sample temperature. The change in temperature with time (thermogram) is recorded for both thermocouples, and compared to a baseline thermogram (without liquid in the pan). The thermograms are then processed (using an equation for thermal energy conservation) for the thermochemical information of interest. The results indicated that the energy reaching the pan is dominated by radiative heat transfer processes, while the dominant thermal process for the reactor sphere is the stored (internal) thermal energy within the sphere material. Sufficient laser power is necessary to detect the fuel thermal-related characteristics, and the required power can differ from one fuel to another. With sufficient laser power, one can detect the preferential vaporization of the lighter and heavier fuel fractions. The total specific heat release obtained for the different conventional and biodiesel fuels used in this investigation were similar to the expected values available in the literature.

Petroleum Refining and its Economic and Technological Impact for the Production of Gasoline in Mexico to 2030

Directory of Open Access Journals (Sweden)

Granados-Hernández Elías

2013-10-01

Full Text Available Gas imports in Mexico have increased in the last few years. Nowadays Mexico has no capacity to meet the demands of this fuel in the next twenty years. In this paper we analyze several oil refining projections that enable the oil supply in Mexico until year 2030, taking into consideration four types of refineries, processing the produc- tion of pure oils in the country, using four mixtures of the higher reserve, consider- ing an import to meet the demand of fuel and once met consider exportation. Modeling was carried out analyzing the volume of refined oil and the required in- vestment, based on the kind of refinery and on the processing units that characterize it. As it was mentioned before, there are different refining projections to meet the demand of gas, but considering that the main oil production in Mexico is heavy. The simulated projection with this type of oil would require a higher volume in the exis- tent refineries in the country to meet that demand. Besides, considering the kind of refinery (out of four, the volumes to refine will be less, if very complex refineries are used. However, the cost of investment in this technology would be higher, consider- ing that new refineries will be built in a near future to meet the fuel demands.

'green' petroleum, the take-off time

International Nuclear Information System (INIS)

Bauer, A.

2005-01-01

Replacing gasoline by a synthetic fuel coming from beet root, wheat or colza is no longer a dream. With the rise of crude oil prices, the bio-fuels are reaching the competitiveness threshold. They would help the farmers to stay on their land by giving an answer to the energy problem. France is investing in this energy source and several bio-fuel production plants have been built for the production of bio-diesel (Diester) and ethanol. However, oil companies express their reserve with respect to ethanol because refineries already produce too much gasoline and not enough diesel fuels. Short paper. (J.S.)

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

natural gas and the amount of fossil natural gas used for hydrogen production is reduced; however, internal hydrogen production also reduces the potential petroleum energy savings (per unit of biomass input basis) because the fuel yield declines dramatically. Typically, a process that has a greater liquid fuel yield results in larger petroleum savings per unit of biomass input but a smaller reduction in life-cycle GHG emissions. Sequestration of the large amount of bio-char co-product (e.g., in soil applications) provides a significant carbon dioxide credit, while electricity generation from bio-char combustion provides a large energy credit. The WTW energy and GHG emissions benefits observed when a pyrolysis oil refinery was integrated with a pyrolysis reactor were small when compared with those that occur when pyrolysis oil is distributed to a distant refinery, since the activities associated with transporting the oil between the pyrolysis reactors and refineries have a smaller energy and emissions footprint than do other activities in the pyrolysis pathway.

Comparative study of Fischer–Tropsch production and post-combustion CO2 capture at an oil refinery: Economic evaluation and GHG (greenhouse gas emissions) balances

Johansson, Daniella; Franck, Per-Åke; Pettersson, Karin; Berntsson, Thore

2013-01-01

The impact on CO 2 emissions of integrating new technologies (a biomass-to-Fischer–Tropsch fuel plant and a post-combustion CO 2 capture plant) with a complex refinery has previously been investigated separately by the authors. In the present study these designs are integrated with a refinery and evaluated from the point-of-view of economics and GHG (greenhouse gas emissions) emissions and are compared to a reference refinery. Stand-alone Fischer–Tropsch fuel production is included for comparison. To account for uncertainties in the future energy market, the assessment has been conducted for different future energy market conditions. For the post-combustion CO 2 capture process to be profitable, the present study stresses the importance of a high charge for CO 2 emission. A policy support for biofuels is essential for the biomass-to-Fischer–Tropsch fuel production to be profitable. The level of the support, however, differs depending on scenario. In general, a high charge for CO 2 economically favours Fischer–Tropsch fuel production, while a low charge for CO 2 economically favours Fischer–Tropsch fuel production. Integrated Fischer–Tropsch fuel production is most profitable in scenarios with a low wood fuel price. The stand-alone alternative shows no profitability in any of the studied scenarios. Moreover, the high investment costs make all the studied cases sensitive to variations in capital costs. - Highlights: • Comparison of Fischer–Tropsch (FT) fuel production and CO 2 capture at a refinery. • Subsidies for renewable fuels are essential for FT fuel production to be profitable. • A high charge for CO 2 is essential for post-combustion CO 2 capture to be profitable. • A low charge for CO 2 economically favours FT fuel production. • Of the studied cases, CO 2 capture shows the greatest reduction in GHG emissions

Processing of crude oil has been carried out in Ghana for more than four decades without measures to assess the hazards associated with the naturally occurring radionuclides in the raw and processed materials. This study investigates the exposure of the public to 226 Ra, 232 Th and 40 K in crude oil, petroleum products and wastes at the Tema oil refinery in Ghana using gamma-ray spectrometry. The study shows higher activity concentrations of the natural radionuclides in the wastes than the crude oil and the products with estimated hazard indices less than unity. The values obtained in the study are within recommended limits for public exposure indicating that radiation exposure from processing of the crude oil at the refinery does not pose any significant radiological hazard but may require monitoring to establish long-term effect on both public and workers.

Full Text Available Storage tanks condition and integrity is maintained by joint application of coating and cathodic protection. Iraq southern region rich in oil and petroleum product refineries need and use plenty of aboveground storage tanks. Iraq went through conflicts over the past thirty five years resulting in holding the oil industry infrastructure behind regarding maintenance and modernization. The primary concern in this work is the design and implementation of cathodic protection systems for the aboveground storage tanks farm in the oil industry. Storage tank external base area and tank internal surface area are to be protected against corrosion using impressed current and sacrificial anode cathodic protection systems. Interactive versatile computer programs are developed to provide the necessary system parameters data including the anode requirements, composition, rating, configuration, etc. Microsoft-Excel datasheet and Visual Basic.Net developed software were used throughout the study in the design of both cathodic protection systems. The case study considered in this work is the eleven aboveground storage tanks farm situated in al-Shauiba refinery in southern IRAQ. The designed cathodic protection systems are to be installed and monitored realistically in the near future. Both systems were designed for a life span of (15-30 years, and all their parameters were within the internationally accepted standards.

In this work, the evaluation of a catalyst based on beta zeolite agglomerated with bentonite in the hydroisomerization of three feeds obtained by distillation of refinery naphtha streams provided by the petroleum company REPSOL-YPF was considered. These refinery naphthas were different in composition, being constituted mostly by different proportions of paraffin, aromatic and naphthenic compounds. The highest overall paraffin conversion value was obtained with that naphtha with the highest content in linear paraffins. As the classical hydroisomerization mechanism predicts, linear alkanes were transformed into branched isomers. Thus, the relation between branched isomers and linear paraffins (iC6/nC6, iC7/nC7 and iC8/nC8) was higher in the products than in the feed. The presence of the aromatic compounds (benzene and toluene) was detected in the three feeds. In all cases, a complete benzene conversion, leading to naphthenic compounds formation, was reached. Long-term tests showed that, regardless of the type of naphtha fed to the reactor, the research octane number of the products remained practically constant. (author)

The author of the contribution under consideration reports on the BASF perspective according to opportunities and challenges at the interface between petrochemistry and refinery. This contribution is divided into the following chapters: (a) Overview BASF-Group; (b) Overview BASF Petrochemicals; (c) The refinery-chemistry interface; (d) Main focus refineries; (e) Interface challenges and opportunities; (f) What can BASF do for refineries. BASF employs the Verbund concept, a system that combines production with energy needs in an intelligent way. The idea is to reduce of primary energy carriers both in terms of raw materials and for power and steam generation. The authors describes the petrochemicals of BASF AG (Ludwigshafen, Federal Republic of Germany), the raw material development, evolution of thermal steamcracking and crackerproducts. Major feedstock source of the European petrochemical industry are streams out of refineries which can't be used for transportation fuels. The gap between propylene demand and production out of steam crackers has to be closed by propylene out for FCC's. Demand for aromatics (xylenes and benzene, and to a lesser extent toluene) needs to be filled in by aromatics out of refineries. Market drivers for the refining industry are lowering crude costs, growing clean products, increasing capacity and enhancing E and P integration. BASF has various business with the oil und refining industry and provides solutions for oil field chemicals, process chemicals and performance additives. The author explains which kind of products and services BASF provides for refiners.

Logistics aspects of pipeline transport in the supply of petroleum products

Directory of Open Access Journals (Sweden)

Wessel Pienaar

2008-09-01

Full Text Available The commercial transportation of crude oil and petroleum products by pipeline is receiving increased attention in South Africa. Transnet Pipeline Transport has recently obtained permission from the National Energy Regulator of South Africa (Nersa to construct and operate a new petroleum products pipeline of 60 cm diameter from Durban to Gauteng. At an operating speed of 10 km/h the proposed 60 cm Transnet pipeline would be able to deliver 3,54 million litres of petroleum product per hour. This is equivalent to 89 deliveries per hour using road tank vehicles with an average carrying capacity of 40 000 litres of fuel per vehicle. This pipeline throughput is also equivalent to two trains departing per hour, each consisting of 42 petroleum tank wagons with an average carrying capacity of 42 500 litres of fuel per wagon. Considering that such road trucks and rail wagons return empty to the upstream refineries in Durban, it is clear that there is no tenable long-term alternative to pipeline transport:pipeline transport is substantially cheaper than road and rail transport;pipeline transport is much safer than rail and especially road transport; andpipeline transport frees up alternative road and rail transport capacity.Pipeline transport is a non-containerised bulk mode of transport for the carriage of suitable liquids (for example, petroleum commodities, which include crude oil, refined fuel products and liquid petro-chemicals, gas, slurrified coal and certain water-suspended ores and minerals. InSouth Africa, petroleum products account for the majority of commercial pipeline traffic, followed by crude oil and natural gas. There are three basic types of petroleum pipeline transport systems:Gathering pipeline systemsCrude oil trunk pipeline systemsRefined products pipeline systems Collectively, these systems provide a continuous link between extraction, processing, distribution, and wholesalers’ depots in areas of consumption.

Petroleum and Health Care: Evaluating and Managing Health Care's Vulnerability to Petroleum Supply Shifts

Science.gov (United States)

Bednarz, Daniel; Bae, Jaeyong; Pierce, Jessica

2011-01-01

Petroleum is used widely in health care—primarily as a transport fuel and feedstock for pharmaceuticals, plastics, and medical supplies—and few substitutes for it are available. This dependence theoretically makes health care vulnerable to petroleum supply shifts, but this vulnerability has not been empirically assessed. We quantify key aspects of petroleum use in health care and explore historical associations between petroleum supply shocks and health care prices. These analyses confirm that petroleum products are intrinsic to modern health care and that petroleum supply shifts can affect health care prices. In anticipation of future supply contractions lasting longer than previous shifts and potentially disrupting health care delivery, we propose an adaptive management approach and outline its application to the example of emergency medical services.

Estimating Impacts of Diesel Fuel Reformulation with Vector-based Blending

Energy Technology Data Exchange (ETDEWEB)

Hadder, G.R.

2003-01-23

The Oak Ridge National Laboratory Refinery Yield Model has been used to study the refining cost, investment, and operating impacts of specifications for reformulated diesel fuel (RFD) produced in refineries of the U.S. Midwest in summer of year 2010. The study evaluates different diesel fuel reformulation investment pathways. The study also determines whether there are refinery economic benefits for producing an emissions reduction RFD (with flexibility for individual property values) compared to a vehicle performance RFD (with inflexible recipe values for individual properties). Results show that refining costs are lower with early notice of requirements for RFD. While advanced desulfurization technologies (with low hydrogen consumption and little effect on cetane quality and aromatics content) reduce the cost of ultra low sulfur diesel fuel, these technologies contribute to the increased costs of a delayed notice investment pathway compared to an early notice investment pathway for diesel fuel reformulation. With challenging RFD specifications, there is little refining benefit from producing emissions reduction RFD compared to vehicle performance RFD. As specifications become tighter, processing becomes more difficult, blendstock choices become more limited, and refinery benefits vanish for emissions reduction relative to vehicle performance specifications. Conversely, the emissions reduction specifications show increasing refinery benefits over vehicle performance specifications as specifications are relaxed, and alternative processing routes and blendstocks become available. In sensitivity cases, the refinery model is also used to examine the impact of RFD specifications on the economics of using Canadian synthetic crude oil. There is a sizeable increase in synthetic crude demand as ultra low sulfur diesel fuel displaces low sulfur diesel fuel, but this demand increase would be reversed by requirements for diesel fuel reformulation.

No pressure on Slovnaft to lower fuel prices

Beer, G.; Schoenwiesner, R.; Debnar, M.

2004-01-01

The Bratislava based refinery, Slovnaft has a dominant position on the Slovak fuel market. But this dominant market position is not specific to Slovakia - other national markets also have domestic producers with dominant positions. Fuel prices have increased substantially and the consumers are looking for a c ulprit' and have found it in the major player on the market. All those who are talking of 'record-breaking' fuel prices seem to have forgotten about inflation rates in recent years. But the situation on the Slovak market is not entirely standard. Slovak customers are right in objecting to the fact that fuel prices are often higher in Slovakia (pre-tax) than in neighbouring countries. But there is nothing to indicate this situation is likely to change. The consumption of petrol and diesel in Slovakia is growing. Many well-established companies have left the Slovak market and 50 competition is decreasing. And those that have stayed buy their fuel from Slovnaft and do not exercise any pressure on retail margins. Small independent distributors are not in a position to offer lower prices and they themselves are forced to decrease their margins. Slovnaft, controlled by the Hungarian company MOL, dictates the rules not only because its refineries produce 76% of all fuel sold on the Slovak market but also due to the fact that the company controls 39% of the retail network. It does not make a difference whether drivers stop at non--brand petrol stations, or use the petrol stations of international companies, nearly all companies operating in Slovakia buy their fuel from the Bratislava refinery with the exception of high octane petrol and winter diesel. Despite refinery over-capacity in Central Europe and the high number of producers operating within a small area, competition is not noticeable on the Slovak market. In theory, competition could be provided by the Polish refineries, the Czech refinery which imports under the JET brand, the Austrian owned OMV, the

Production of ethanol from refinery waste gases. Phase 2, technology development, annual report

Oil refineries discharge large volumes of H{sub 2}, CO, and CO{sub 2} from cracking, coking, and hydrotreating operations. This program seeks to develop a biological process for converting these waste gases into ethanol, which can be blended with gasoline to reduce emissions. Production of ethanol from all 194 US refineries would save 450 billion BTU annually, would reduce crude oil imports by 110 million barrels/year and emissions by 19 million tons/year. Phase II efforts has yielded at least 3 cultures (Clostridium ljungdahlii, Isolate O-52, Isolate C-01) which are able to produce commercially viable concentrations of ethanol from CO, CO{sub 2}, and H{sub 2} in petroleum waste gas. Single continuous stirred tank reactor studies have shown that 15-20 g/L of ethanol can be produced, with less than 5 g/L acetic acid byproduct. Culture and reactor optimization in Phase III should yield even higher ethanol concentrations and minimal acetic acid. Product recovery studies showed that ethanol is best recovered in a multi-step process involving solvent extraction/distillation to azeotrope/azeotropic distillation or pervaporation, or direct distillation to the azeotrope/azeotropic distillation or pervaporation. Projections show that the ethanol facility for a typical refinery would require an investment of about $30 million, which would be returned in less than 2 years.

Full Text Available For the present work, a single cylinder diesel engine was modified to work in dual fuel mode. To study the feasibility of using methyl ester of mahua oil as pilot fuel, it was used as pilot fuel and liquefied petroleum gas was used as primary fuel. In dual fuel mode, pilot fuel quantity and injector opening pressure are the few variables, which affect the performance and emission of dual fuel engine. Hence, in the present work, pilot fuel quantity and injector opening pressure were varied. From the test results, it was observed that the pilot fuel quantity of 5 mg per cycle and injector opening pressure of 200 bar results in higher brake thermal efficiency. Also the exhaust emissions such as smoke, unburnt hydrocarbon and carbon monoxide are lower than other pressures and pilot fuel quantities. The higher injection pressure and proper pilot fuel quantity might have resulted in better atomization, penetration of methyl ester of mahua oil and better combustion of fuel.

Bioremediation of Petroleum and Radiological Contaminated Soils at the Savannah River Site: Laboratory to Field Scale Applications

Energy Technology Data Exchange (ETDEWEB)

BRIGMON, ROBINL.

2004-06-07

In the process of Savannah River Site (SRS) operations limited amounts of waste are generated containing petroleum, and radiological contaminated soils. Currently, this combination of radiological and petroleum contaminated waste does not have an immediate disposal route and is being stored in low activity vaults. SRS developed and implemented a successful plan for clean up of the petroleum portion of the soils in situ using simple, inexpensive, bioreactor technology. Treatment in a bioreactor removes the petroleum contamination from the soil without spreading radiological contamination to the environment. This bioreactor uses the bioventing process and bioaugmentation or the addition of the select hydrocarbon degrading bacteria. Oxygen is usually the initial rate-limiting factor in the biodegradation of petroleum hydrocarbons. Using the bioventing process allowed control of the supply of nutrients and moisture based on petroleum contamination concentrations and soil type. The results of this work have proven to be a safe and cost-effective means of cleaning up low level radiological and petroleum-contaminated soil. Many of the other elements of the bioreactor design were developed or enhanced during the demonstration of a ''biopile'' to treat the soils beneath a Polish oil refinery's waste disposal lagoons. Aerobic microorganisms were isolated from the aged refinery's acidic sludge contaminated with polycyclic aromatic hydrocarbons (PAHs). Twelve hydrocarbon-degrading bacteria were isolated from the sludge. The predominant PAH degraders were tentatively identified as Achromobacter, Pseudomonas Burkholderia, and Sphingomonas spp. Several Ralstonia spp were also isolated that produce biosurfactants. Biosurfactants can enhance bioremediation by increasing the bioavailability of hydrophobic contaminants including hydrocarbons. The results indicated that the diversity of acid-tolerant PAH-degrading microorganisms in acidic oil wastes may

The Brazilian petroleum company PETROBRAS is ranked ten in the number of petroleum refineries in the world, has the second greatest number of tanker ships and has greatly contributed to deep waters prospecting. In the last eight years an economic plan for fighting inflation has been adopted by the Brazilian government and, as a consequence, PETROBRAS has been decapitalized preventing the company from developing its projects

Benchmarking of refinery emissions performance : Executive summary

International Nuclear Information System (INIS)

2003-07-01

This study was undertaken to collect emissions performance data for Canadian and comparable American refineries. The objective was to examine parameters that affect refinery air emissions performance and develop methods or correlations to normalize emissions performance. Another objective was to correlate and compare the performance of Canadian refineries to comparable American refineries. For the purpose of this study, benchmarking involved the determination of levels of emission performance that are being achieved for generic groups of facilities. A total of 20 facilities were included in the benchmarking analysis, and 74 American refinery emission correlations were developed. The recommended benchmarks, and the application of those correlations for comparison between Canadian and American refinery performance, were discussed. The benchmarks were: sulfur oxides, nitrogen oxides, carbon monoxide, particulate, volatile organic compounds, ammonia and benzene. For each refinery in Canada, benchmark emissions were developed. Several factors can explain differences in Canadian and American refinery emission performance. 4 tabs., 7 figs

For the purpose of heightening the thermal efficiency in oil refineries in Indonesia, survey was conducted of two main refineries of Pertamina (Cilacap Refinery and Balikpapan Refinery), and a potentiality of spreading energy conservation technology was studied. As a result of the study, the following were found out. In Cilacap Refinery, there is a possibility of energy conservation by enhancing the efficiency of the atmospheric distillation system and rationalizing utility facilities. As to Balikpapan Refinery, when effects of energy conservation are calculated by effectively using the by-producing off-gas emitted from the oil refining process which was recovered as on-site fuel, the amount of reduction in fuel consumption became 2.3 KL-FOE/h, and the year of simple investment recovery 1.7 years. Further, by recovering/effectively using hydrogen in the separation gas emitted from the hydrocracking unit, fuel/raw material in the hydrogen producing facilities were reduced, and the energy conservation effect became 2.98 KL-FOE/h in the amount of reduction in fuel consumption and 2.9 years in the year of simple investment recovery.

The impact of U.S. environmental regulations on fuel quality

International Nuclear Information System (INIS)

Strauss, K.H.; Dukek, W.G.

1993-01-01

The amendments to the Clean Air Act passed in 1990 focused attention on the emissions from mobile sources, such as automobiles and trucks, as they degrade air quality, particularly in urban areas. In legislating the 1990 amendments, it was recognized that a change in gasoline composition could have as great an effect on improved air quality as design changes in the automobile itself. Without lead available to meet vehicle octane requirements, the refiners increased the use of isoparaffinic and aromatic streams as blending components and began a search for replacement octane enhancers. More reforming units were added in refineries to produce streams of high aromatic content, a step that fortuitously produced more hydrogen gas for treating other products, such as jet fuel and heavier middle distillates, to reduce sulfur content and improve stability. The close relationship between motor gasoline and the quality of other products explains why the advent of reformulated gasoline in the 1990s is viewed with concern by refiners, particularly because the government has now decided to also mandate improvements in diesel fuel quality that will require much of the hydrogen that was counted on to treat jet fuels. As a consequence, the fuel subcommittees of Committee D-2 on Petroleum Products decided that the best forum for highlighting the interrelationships between all major fuels and the impending regulations to improve air quality was a symposium. The symposium began with the latest thinking of the Federal and State governments on air quality regulations and results were then presented from the industry Auto/Oil Air Quality Research Program. The impact of these pending changes on petroleum refining was then discussed. Later, the impact on fuel users for various applications and the effect on ASTM standards was presented. Papers have been processed separately for inclusion on the data base

Enhanced treatment of refinery soils with open-system slurry reactors

Blackburn, J.W.; Lee, M.K.; Horn, W.C.

1995-01-01

Refinery site cleanups of residual hydrocarbons arising from long-term operations have become a concern. Because contaminated soil has been generated over many years from spills of many types of materials, it is often difficult to identify the actual spilled material. Because many of these materials are weathered, the less degradable fractions can predominate, creating a challenge for bioremedial process solutions. Open-system slurry reactors were run with an aged refinery soil after a 6-month period of field bioremediation in which 23% TPH removal resulted. The open system (a system where the liquid medium was replaced daily and the solids were retained in the reactor for 2 weeks) achieved 60 to 80% total petroleum hydrocarbon (TPH) removal based on the initial, prefield bioremediation soil concentration. A process concept twice as effective as other bioremediation schemes has been devised that takes advantage of the formation and removal of small black particulate solids in an open or continuous slurry reactor configuration. These small black particles are chemically or biologically produced in the open system and with their small size and low density are easily elutriated from the bioreactor as the liquid medium is changed. A statistically designed experiment has determined optimal values of nutrients, temperature, and mixing

Thermophilic slurry-phase treatment of petroleum hydrocarbon waste sludges

1995-01-01

Chemoheterotrophic thermophilic bacteria were used to achieve enhanced hydrocarbon degradation during slurry-phase treatment of oily waste sludges from petroleum refinery operations. Aerobic and anaerobic bacterial cultures were examined under thermophilic conditions to assess the effects of mode of metabolism on the potential for petroleum hydrocarbon degradation. The study determined that both aerobic and anaerobic thermophilic bacteria are capable of growth on petroleum hydrocarbons. Thermophilic methanogenesis is feasible during the degradation of hydrocarbons when a strict anaerobic condition is achieved in a slurry bioreactor. Aerobic thermophilic bacteria achieved the largest apparent reduction in chemical oxygen demand, freon extractable oil, total and volatile solid,s and polycyclic aromatic hydrocarbons (PAHs) when treating oily waste sludges. The observed shift with time in the molecular weight distribution of hydrocarbon material was more pronounced under aerobic metabolic conditions than under strict anaerobic conditions. The changes in the hydrocarbon molecular weight distribution, infrared spectra, and PAH concentrations during slurry-phase treatment indicate that the aerobic thermophilic bioslurry achieved a higher degree of hydrocarbon degradation than the anaerobic thermophilic bioslurry during the same time period

This paper summarizes the results of a 5-y research study of the nature and toxicity of petroleum biodegradation metabolites in groundwater at fuel release sites that are quantified as diesel-range "Total Petroleum Hydrocarbons" (TPH; also known as TPHd, diesel-range organics (DRO), etc.), unless a silica gel cleanup (SGC) step is used on the sample extract prior to the TPH analysis. This issue is important for site risk management in regulatory jurisdictions that use TPH as a metric; the presence of these metabolites may preclude site closure even if all other factors can be considered "low-risk." Previous work has shown that up to 100% of the extractable organics in groundwater at petroleum release sites can be biodegradation metabolites. The metabolites can be separated from the hydrocarbons by incorporating an SGC step; however, regulatory agency acceptance of SGC has been inconsistent because of questions about the nature and toxicity of the metabolites. The present study was conducted to answer these specific questions. Groundwater samples collected from source and downgradient wells at fuel release sites were extracted and subjected to targeted gas chromatography-mass spectrometry (GC-MS) and nontargeted two-dimensional gas chromatography with time-of-flight mass spectrometry (GC×GC-MS) analyses, and the metabolites identified in each sample were classified according to molecular structural classes and assigned an oral reference dose (RfD)-based toxicity ranking. Our work demonstrates that the metabolites identified in groundwater at biodegrading fuel release sites are in classes ranked as low toxicity to humans and are not expected to pose significant risk to human health. The identified metabolites naturally attenuate in a predictable manner, with an overall trend to an increasingly higher proportion of organic acids and esters, and a lower human toxicity profile, and a life cycle that is consistent with the low-risk natural attenuation paradigm adopted

Nowadays the refining sector in Mexico needs to increase the quantity and quality of produced fuels by installing new process plants for gasoline and ultra-low sulphur diesel. These plants require the provision of electricity and steam, among other services to function properly, which can be supplied by the power plants currently installed in each refinery through an expansion of their generation capacity. These power plants need to increase its production of electricity and steam at levels above their installed capacity, which involves the addition of new power generating equipment (gas or steam turbo-generators) as well as the raise of the electrical loads. Currently, the Mexican Petroleum Company (PEMEX) is planning to restructure their electrical and steam systems in order to optimally supply the required services for the production of high quality fuels. In this paper the present status of the original electrical power systems of the refineries is assessed and the electrical integration of new process plants in the typical schemes is analyzed. Also this paper shows the conceptual schemes proposed to restructure the electrical power system for two refineries and the strategic planning focused on implement the modifications required for the integration of new process plants that will demand about 20 MW for each refinery by 2014. The results of the analysis allowed to identify the current conditions of the electrical power systems in the oil refining industry or National Refining Industry (NRI), and thereby to offer technical solutions that could be useful to engineers facing similar projects.

Metallic elements found in the aquatic environment may originate in areas where petroleum is refined and vessels are maintained and repaired. This study aims to assess contamination caused by nickel (Ni), lead (Pb), and vanadium (V) in sediment of the Lagoa dos Patos estuary (RS, Brazil) and to evaluate them as indicators of areas under the influence of petroleum products and antifouling paints. Surface sediments were collected in summer and in winter in areas of marinas, shipyards, refinery, and a control station. High Pb and V concentrations in shipyards and at the Yacht Club showed that some organisms may be affected by toxicity. High Pb results of the index of geoaccumulation (Igeo) were found at the Yacht Club and shipyards. Al, Ni, and V had similar distribution in the sediment in both seasons. Ni and V had high relation in winter at the Yacht Club and at the Santos Shipyard, thus suggesting that these elements come mainly from petroleum products. The same happened to the relations between Pb and V, as well as Pb and Ni at the Santos Shipyard. These elements are employed as useful tools as indicators to identify places with moderate to high localized anthropogenic inputs of petroleum derivatives and antifouling paints.

Complexity index indicates refinery capability, value

International Nuclear Information System (INIS)

Johnston, D.

1996-01-01

Refinery size usually is measured in terms of distillation capacity. Relative size, however, can be measured using refinery complexity--a concept developed by W.L. Nelson in the 1960s. Nelson developed the complexity index to quantify the relative cost of components that make up a refinery. It is a pure cost index that provides a relative measure of the construction costs of a particular refinery based on its crude and upgrading capacity. The Nelson index compares the costs of various upgrading units--such as a fluid catalytic cracking (FCC) unit or a catalytic reformer--to the cost of a crude distillation unit. Computation of the index is an attempt to quantify the relative cost of a refinery based on the added cost of various upgrading units and the relative upgrading capacity. A review of complexity calculations, and an explanation of how indices have changed, provide a simple means of determining the complexity of single refineries or refining regions. The impact of complexity on product slate is also examined in this paper

Treating refinery wastewaters in microbial fuel cells using separator electrode assembly or spaced electrode configurations

KAUST Repository

Zhang, Fang

2014-01-01

The effectiveness of refinery wastewater (RW) treatment using air-cathode, microbial fuel cells (MFCs) was examined relative to previous tests based on completely anaerobic microbial electrolysis cells (MECs). MFCs were configured with separator electrode assembly (SEA) or spaced electrode (SPA) configurations to measure power production and relative impacts of oxygen crossover on organics removal. The SEA configuration produced a higher maximum power density (280±6mW/m2; 16.3±0.4W/m3) than the SPA arrangement (255±2mW/m2) due to lower internal resistance. Power production in both configurations was lower than that obtained with the domestic wastewater (positive control) due to less favorable (more positive) anode potentials, indicating poorer biodegradability of the RW. MFCs with RW achieved up to 84% total COD removal, 73% soluble COD removal and 92% HBOD removal. These removals were higher than those previously obtained in mini-MEC tests, as oxygen crossover from the cathode enhanced degradation in MFCs compared to MECs. © 2013 Elsevier Ltd.

The energy efficiency of crude oil refining in Brazil: A Brazilian refinery plant case

International Nuclear Information System (INIS)

Lima, Romulo S. de; Schaeffer, Roberto

2011-01-01

This article evaluates energy efficiency in Brazilian crude oil refining in comparison with the crude oil refining in the United States between 1930 and 2008. It aims to show that increased refinery complexity reduces the energy consumption of products of high value added. Moreover, the article shows that improvements in energy efficiency result in higher quality products and increased processing of oil. A Brazilian refinery with a capacity of 157,000 barrels per day (kbpd) was modernized in 2008 at a cost of US $1.3 billion. As a result, its capacity increased by 17%, from 157 to 189 kbpd. Its complexity index also rose from 3.2 to 6.8, allowing an improvement in the EII (energy intensity index) from 110% to 93%. In relation to the crude oil processed before being modernized, energy consumption fell from 0.75 to 0.52 MBtu (million British thermal units) per barrel processed. These proceedings show that increases in complexity reduce the energy consumed in the production of final products with high value added, such as gasoline, diesel and jet fuel. -- Highlights: → Increased refinery complexity reduces the energy consumption of products of high value added. → Improvements in refinery energy efficiency result in higher quality products and increased processing of oil. → Brazilian refineries were not affected significantly in the 2008 crisis, such as the US refineries, due to many factors. → The EII of Brazilian refining presents real opportunities for gains through changes in the profile of energy consumed.

2015-01-01

Numerical investigations of combustion characteristics of methane-hydrogen fuel used at present in tube furnaces of some petroleum refineries are carried out and possible problems related to change-over of existing furnaces from natural gas to methane-hydrogen fuel are analyzed. The effect of the composition of the blended fuel, associated temperature and emissivity of combustion products, temperature of combustion chamber walls, mean beam length, and heat release on variation in the radiation heat flux is investigated. The methane concentration varied from 0 to 100%. The investigations were carried out both at arbitrary given gas temperatures and at effective temperatures determined based on solving a set of equations at various heat-release rates of the combustion chamber and depended on the adiabatic combustion temperature and the temperature at the chamber output. The approximation dependence for estimation of the radiation heat exchange rate in the radiant chamber of the furnace at change-over to fuel with a greater hydrogen content is obtained. Hottel data were applied in the present work in connection with the impossibility to use approximated formulas recommended by the normative method for heat calculation of boilers to determine the gas emissivity, which are limited by the relationship of partial pressures of water steam and carbon dioxide in combustion products . The effect of the methane-hydrogen fuel on the equilibrium concentration of nitrogen oxides is also investigated.

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

The significant increase of number of facultative oligotrophs in the river Sava water downstream of wastewater discharge (between 70- and almost 100-fold higher number) direct to the conclusion that oligotrophic bacteria (adapted to the environments with low amount of easy-to-degrade nutrients, oligocarbophilic microorganisms) could be better indicator of water bioremediation potential than number of heterotrophic (THR) bacteria. Quantitative composition of heterotrophic, facultative oligotrophic, crude oil degrading, and other physiological groups of bacteria, being, as a rule, higher in samples taken downstream of the waste-water discharge, testify about high biodegradative potential of the River Sava microbial community, if the oil refinery wastewater is taken into consideration.

The motivation of this work was to investigate a biological treatment system, which requires low installation area and presents high flexibility. Thus, a laboratory scale aerated submerged fixed-film bioreactor was applied to the treatment of a petroleum refinery wastewater and its performance was monitored. The reactor was continuously operated during 260 days and submitted to different organic loadings in the range of 0.5 to 2.4 kgCOD.m{sup -3}.d{sup -1}. The following removal efficiencies were attained: COD (75 - 91%), TSS and TVS (60 - 92%) and DOC (56 - 91%) and turbidity (71 - 95%). The reactor presented a high level of mixing and showed to be stable when submitted to different hydraulic and organic loadings. Loss of biofilm was negligible and medium clogging problems were not observed. The support medium (PVC plates) showed to be very adequate for microbial adhesion and growth, resulting in stable bioreactor operation. (author)

A destilação simulada na indústria do petróleo Simulated distillation in the petroleum industry

Directory of Open Access Journals (Sweden)

Alexandre de Andrade Ferreira

2005-06-01

Full Text Available One of the most widely used physico-chemical characterizations of hydrocarbon mixtures is the determination of their boiling point distribution. Knowledge of the boiling range of crude oils and petroleum products is essential to ensure the correct specification of final products and to control refinery processes. Simulated distillation, a GC based process, has been playing this role for the past decades in the petroleum industry. The main purpose of this work is to show the fundamentals of this technique as well as its present trends.

Fluid in a pipeline or container at a refinery or at any of various petroleum producing operations is bombarded with neutrons and high energy gamma rays resulting from capture of thermal neutrons are detected. The spectra of the detected gamma rays are then analyzed to determine the concentration of the element chlorine, which gives an indication of the presence and concentration of salt water in the fluid. The concentration of sulfur and the percentage gas in the fluid may be determined simultaneously with the concentration of chlorine. (Auth.)

The paper reviews the history, present position and future prospects of the petroleum industry in the USA. The main focus is on supply and demand, the high quality of the products, refinery capacity and product trade balances. Diagrams show historical trends in output, product demand, demand for transport fuels and oil, refinery capacity, refinery closures, and imports and exports. Some particularly salient points brought out were (i) production of US crude shows a marked downward trend but imports of crude will continue to increase, (ii) product demand will continue to grow even though the levels are already high, (iii) the demand is dominated by those products that typically yield the highest income for the refiner, (i.e. high quality transport fuels for environmental compliance), (iv) refinery capacity has decreased since 1980 and (v) refining will continue to have financial problems but will still be profitable.
