Venezuelan energy  

SciTech Connect

This paper reports that because military and political instability in the Persian Gulf makes the United States vulnerable to oil supply disruptions, a 1991 Department of Energy report encourages diversification of U.S. oil sources and greater reliance on imports from countries outside the Gulf, such as Venezuela. GAO's report, also published in Spanish, discusses recent increases in Venezuelan oil production and the main factors affecting continued increases through 1996, assesses recent investment reforms in the Venezuelan petroleum industry and U.S. petroleum companies' response to these reforms, identifies the major impediments and inducements to U.S. investment in Venezuela's petroleum industry, and reviews U.S. government efforts to support Venezuela's energy sector.

Naphthenic acid corrosion by Venezuelan crudes  

SciTech Connect

Venezuelan crudes can contain levels of naphthenic acids that cause corrosion in distillation units designed for sweet crudes. This naphthenic acid corrosion can be mitigated in several ways, the most common of which is selective alloying. This paper will provide information from field experience on how various refineries worldwide have upgraded materials to run Venezuelan crudes in a cost effective way.

The Venezuelan natural gas industry  

SciTech Connect

Venezuela's consumption energy of comes from three primary sources: hydroelectricity, liquid hydrocarbons and natural gas. In 1986, the energy consumption in the internal market was 95.5 thousand cubic meters per day of oil equivalent, of which 32% was natural gas, 46% liquid hydrocarbons and 22% hydroelectricity. The Venezuelan energy policy established natural gas usage after hydroelectricity, as a substitute of liquid hydrocarbons, in order to increase exports of these. This policy permits a solid development of the natural gas industry, which is covered in this paper.

Impacts of the Venezuelan Crude Oil Production Loss Impacts of the Venezuelan Crude Oil Production Loss EIA Home > Petroleum > Petroleum Feature Articles Impacts of the Venezuelan Crude Oil Production Loss Printer-Friendly PDF Impacts of the Venezuelan Crude Oil Production Loss By Joanne Shore and John Hackworth1 Introduction The loss of almost 3 million barrels per day of crude oil production in Venezuela following a strike in December 2002 resulted in an increase in the world price of crude oil. However, in the short term, the volume loss probably affected the United States more than most other areas. This country receives more than half of Venezuela's crude and product exports, and replacing the lost volumes proved difficult. U.S. imports of Venezuelan crude oil dropped significantly in December 2002 relative to other years

Focus on Venezuelan heavy crude: refining margins  

SciTech Connect

Of six crudes refined in the US Gulf Coast, heavy Venezuelan crude Lagunillas (15/sup 0/ API) provides the best margin per barrel. Data for end of December 1983 and the first three weeks of January show that margins on all crudes are on the rise in this market, due to a turnaround in product prices. The lighter crudes are showing the greatest increase in Gross Product Worth. This is having a modest shrinking effect on the margin differential between light and heavy crudes in this market. The domestic crude West Texas Intermediate, at 40/sup 0/ API, provides the highest GPW in this crude slate sample, over US $31 per barrel, compared to GPW of under US $28 per barrel for Lagunillas. Still, as Lagunillas cost about US $8 less than does WTI, refiners with sufficient residue conversion capacity can be earning about US $3.50 more in margin per barrel than they can with WTI. Although few refiners would be using a 15/sup 0/ API crude exclusively for any length of time, heavier oil's inclusion in modern refiners' diets is enhancing their competitive position more than any other single factor. This issue of Energy Detente presents the fuel price/tax series and industrial fuel prices for January 1984 for countries of the Western Hemisphere.

Seismic properties of a Venezuelan heavy oil in water emulsion  

SciTech Connect

Several procedures for the production of low-viscosity, surfactant-stabilized, easy-transportable dispersions of heavy crude oil in water-briefly, oil in water (or o/w) emulsions - have been recently patented. Some of them propose to form the o/w emulsion in the reservoir, after the injection of a mixture of water and surfactants, increasing significantly the per well daily production. Progression of the o/w emulsion front, through the reservoir to the production wells, can be monitored in seismic planar slices with successive 3D seismic surveys (413 seismic), if enough contrast exists between the seismic velocity value of the o/w emulsion and the one of the oil in place. To facilitate the analysis of the contrast, this study presents high frequency acoustic velocity measurements performed in the laboratory. The experimental setup includes two reflectors and an ultrasonic transducer with double burst train emission. The estimated velocity precision is 0.02%. The measured samples are: a Venezuelan heavy o/w emulsion, a mixture of the same heavy oil and gasoil and a saturated sandstone core containing the o/w emulsion. Additionally, seismic velocities of the actual pore fluids - live oil and five o/w emulsion - and saturated sandstone are calculated using the above laboratory measurements, Wood`s equation, and Gassman`s and Biot`s models.

Venezuelan equine encephalitis virus entry mechanism requires late endosome formation and resists cell membrane cholesterol depletion  

SciTech Connect

Virus envelope proteins determine receptor utilization and host range. The choice of receptor not only permits specific targeting of cells that express it, but also directs the virus into specific endosomal trafficking pathways. Disrupting trafficking can result in loss of virus infectivity due to redirection of virions to non-productive pathways. Identification of the pathway or pathways used by a virus is, thus, important in understanding virus pathogenesis mechanisms and for developing new treatment strategies. Most of our understanding of alphavirus entry has focused on the Old World alphaviruses, such as Sindbis and Semliki Forest virus. In comparison, very little is known about the entry route taken by more pathogenic New World alphaviruses. Here, we use a novel contents mixing assay to identify the cellular requirements for entry of a New World alphavirus, Venezuelan equine encephalitis virus (VEEV). Expression of dominant negative forms of key endosomal trafficking genes shows that VEEV must access clathrin-dependent endocytic vesicles for membrane fusion to occur. Unexpectedly, the exit point is different from Old World alphaviruses that leave from early endosomes. Instead, VEEV also requires functional late endosomes. Furthermore, unlike the Old World viruses, VEEV entry is insensitive to cholesterol sequestration from cell membranes and may reflect a need to access an endocytic compartment that lacks cholesterol. This indicates fundamental differences in the entry route taken by VEEV compared to Old World alphaviruses.

Structure of a Venezuelan equine encephalitis virus assembly intermediate isolated from infected cells  

SciTech Connect

Venezuelan equine encephalitis virus (VEEV) is a prototypical enveloped ssRNA virus of the family Togaviridae. To better understand alphavirus assembly, we analyzed newly formed nucleocapsid particles (termed pre-viral nucleocapsids) isolated from infected cells. These particles were intermediates along the virus assembly pathway, and ultimately bind membrane-associated viral glycoproteins to bud as mature infectious virus. Purified pre-viral nucleocapsids were spherical with a unimodal diameter distribution. The structure of one class of pre-viral nucleocapsids was determined with single particle reconstruction of cryo-electron microscopy images. These studies showed that pre-viral nucleocapsids assembled into an icosahedral structure with a capsid stoichiometry similar to the mature nucleocapsid. However, the individual capsomers were organized significantly differently within the pre-viral and mature nucleocapsids. The pre-viral nucleocapsid structure implies that nucleocapsids are highly plastic and undergo glycoprotein and/or lipid-driven rearrangements during virus self-assembly. This mechanism of self-assembly may be general for other enveloped viruses.

Quick Anomaly Detection by the Newcomb--Benford Law, with Applications to Electoral Processes Data from the USA, Puerto Rico and Venezuela  

E-Print Network (OSTI)

A simple and quick general test to screen for numerical anomalies is presented. It can be applied, for example, to electoral processes, both electronic and manual. It uses vote counts in officially published voting units, which are typically widely available and institutionally backed. The test examines the frequencies of digits on voting counts and rests on the First (NBL1) and Second Digit Newcomb--Benford Law (NBL2), and in a novel generalization of the law under restrictions of the maximum number of voters per unit (RNBL2). We apply the test to the 2004 USA presidential elections, the Puerto Rico (1996, 2000 and 2004) governor elections, the 2004 Venezuelan presidential recall referendum (RRP) and the previous 2000 Venezuelan Presidential election. The NBL2 is compellingly rejected only in the Venezuelan referendum and only for electronic voting units. Our original suggestion on the RRP (Pericchi and Torres, 2004) was criticized by The Carter Center report (2005). Acknowledging this, Mebane (2006) and The...

Venezuela and Brazil promise enormous rewards for international oil and gas companies that help them realize their production goals--but risk partially offsets the potential rewards, and neither nation is giving anything away.

As usual in these situations, the middle ground doesn't make either side extremely happy, but both have agreements they can live with. Economics and politics are discussed. The paper also describes Brazilian potential, Venezuelan investment, licensing in Brazil, Venezuelan activity and Brazil blocks.

3 3 1 Short-Term Energy Outlook April 2003 Summer 2003 Motor Gasoline Outlook Summary For the upcoming summer season (April to September 2003), high crude oil costs and other factors are expected to yield average retail motor gasoline prices higher than those of last year. Current crude oil prices reflect a substantial uncertainty premium due to concerns about the current conflict in the Persian Gulf, lingering questions about whether Venezuelan oil production will recover to near pre-strike levels in time for the peak driving season, and the impact of recent disruptions in Nigerian oil output. Moreover, unusually low crude oil and gasoline inventory levels at the outset of the driving season are expected to keep prices high throughout much of the

Short Term Energy Outlook, February 2003  

Gasoline and Diesel Fuel Update (EIA)

3 3 1 Short-Term Energy Outlook February 2003 Overview World Oil Markets. World oil markets will likely remain tight through most of 2003, as petroleum inventories and global spare production capacity continue to dwindle amid blasts of cold weather and constrained output from Venezuela. OPEC efforts to increase output to make up for lower Venezuela output has reduced global spare production capacity to only 2 million barrels per day, leaving little room to make up for unexpected supply or demand surprises. Meanwhile, the average West Texas Intermediate (WTI) crude oil price increased by $3.50 to $33 per barrel from December to January (Figure 1). For the year 2003, WTI oil prices are expected to remain over $30 per barrel, even though Venezuelan output appears to be moving toward normal sooner than expected. Also,

Crude Oil Imports From Persian Gulf

Crude Oil Imports From Persian Gulf Crude Oil Imports From Persian Gulf January - June 2013 | Release Date: August 29, 2013 | Next Release Date: February 27, 2014 2013 Crude Oil Imports From Persian Gulf Highlights It should be noted that several factors influence the source of a company's crude oil imports. For example, a company like Motiva, which is partly owned by Saudi Refining Inc., would be expected to import a large percentage from the Persian Gulf, while Citgo Petroleum Corporation, which is owned by the Venezuelan state oil company, would not be expected to import a large percentage from the Persian Gulf, since most of their imports likely come from Venezuela. In addition, other factors that influence a specific company's sources of crude oil imports would include the characteristics of various crude oils as well as a company's economic

Short-Term Energy Outlook  

Gasoline and Diesel Fuel Update (EIA)

3 3 1 Short-Term Energy Outlook April 2003 Overview World Oil Markets. Crude oil prices fell sharply at the onset of war in Iraq, but the initial declines probably overshot levels that we consider to be generally consistent with fundamental factors in the world oil market. Thus, while near-term price averages are likely to be below our previous projections, the baseline outlook for crude oil prices (while generally lower) is not drastically different and includes an average for spot West Texas Intermediate (WTI) that is close to $30 per barrel in 2003 (Figure 1). The mix of uncertainties related to key oil production areas has changed since last month, as Venezuelan production has accelerated beyond previous estimates while Nigerian output has been reduced due to internal conflict.

Gasoline and Diesel Fuel Update (EIA)

3 3 1 Short-Term Energy Outlook March 2003 Overview World Oil Markets. February crude oil prices moved higher than expected pushed by fears of a war in Iraq, low inventories, slow recovery in Venezuelan exports, continued cold weather and sharply higher natural gas prices in the United States. West Texas Intermediate prices averaged close to $36 for the month (Figure 1), a level not seen since October 1990. Oil inventories continued lower through the month resulting in a cumulative reduction in total commercial stocks of 101 million barrels since September 30, 2002, the beginning of the heating season. Total OECD inventories reached an estimated 2,424 million barrels at the end of February, which would be the lowest level since

Venezuela positioning itself to take key market role in wake of Gulf War  

SciTech Connect

This paper reports on Venezuela which continues efforts to position itself in world markets to capitalize on fallout from the Persian Gulf war. The central government and state oil company Petroleos de Venezuela SA have accelerated already ambitious plans to expand activities in upstream and downstream oil and gas sectors. Pvdsa has sharply increased its 1991-96 investment program from the level planned at the end of last year. The goal is to put Venezuela on a par with major Persian Gulf oil exporters in terms of productive capacity. Linchpin of those efforts could well be further steps toward privatization of Venezuela's oil sector. For the first time since nationalization in 1976, private foreign and domestic companies are being permitted to participate in Venezuelan exploration and development. In addition, the government is trimming the onerous tax burden the oil sector has carried in Venezuela, as well as its heavy subsidy of domestic petroleum products.

Optimization of catalyst system reaps economic benefits  

SciTech Connect

Champlin Refining and Chemicals Inc. is learning to optimize its catalyst systems for hydrotreating Venezuelan gas oils through a program of research, pilot plant testing, and commercial unit operation. The economic results of this project have been evaluated, and the benefits are most evident in improvements in product yields and qualities. The project has involved six commercial test runs, to date (Runs 10-15), with a seventh run planned. A summary of the different types of catalyst systems used in the test runs, and the catalyst philosophy that developed is given. Runs 10 and 11 used standard CoMo and NiMo catalysts for heavy gas oils hydrotreating. These catalysts had small pore sizes and suffered high deactivation rates because of metals contamination. When it was discovered that metals contamination was a problem, catalyst options were reviewed.

THE WEATHERING OF A SULFIDE OREBODY: SPECIATION AND FATE OF SOME POTENTIAL CONTAMINANTS  

SciTech Connect

Various potentially toxic trace elements such as As, Cu, Pb and Zn have been remobilized by the weathering of a sulfide orebody that was only partially mined at Leona Heights, California. As a result, this body has both natural and anthropogenically modified weathering profiles only 500 m apart. The orebody is located in a heavily urbanized area in suburban Oakland, and directly affects water quality in at least one stream by producing acidic conditions and relatively high concentrations of dissolved elements (e.g., {approx}500 mg/L Cu, {approx}3700 mg/L Zn). Micrometric-scale mineralogical investigations were performed on the authigenic metal-bearing phases (less than 10 {mu}m in size) using electron-probe micro-analysis (EPMA), micro-Raman, micro X-ray absorption spectroscopy (mXAS), scanning X-ray diffraction (mSXRD) and scanning X-ray fluorescence (mSXRF) mapping techniques. Those measurements were coupled with classical mineralogical laboratory techniques, X-ray diffraction (XRD) and scanning electron microscopy (SEM). Authigenic metal-bearing phases identified are mainly sulfates (jarosite, epsomite, schwertmannite), Fe (oxy-)hydroxides (goethite, hematite and poorly crystalline Fe products) and poorly crystalline Mn (hydr-)oxides. Sulfates and Fe (oxy-)hydroxides are the two main secondary products at both sites, whereas Mn (hydr-) oxides were only observed in the samples from the non-mining site. In these samples, the various trace elements show different affinities for Fe or Mn compounds. Lead is preferentially associated with Mn (hydr-)oxides and As with Fe (oxy-)hydroxides or sulfates. Copper association with Mn and Fe phases is questionable, and the results obtained rather indicate that Cu is present as individual Cu-rich grains (Cu hydroxides). Some ochreous precipitates were found at both sites and correspond to a mixture of schwertmannite, goethite and jarosite containing some potentially toxic trace elements such as Cu, Pb and Zn. According to the trace element distribution and relative abundance of the unweathered sulfides, this orebody still represents a significant reservoir of potential contaminants for the watershed, especially in the non-mining site, as a much greater proportion of sulfides is left to react and because of the lower porosity in this site.

Chapter Five - Arboviruses Pathogenic for Domestic and Wild Animals  

Science Journals Connector (OSTI)

Abstract The objective of this chapter is to provide an updated and concise systematic review on taxonomy, history, arthropod vectors, vertebrate hosts, animal disease, and geographic distribution of all arboviruses known to date to cause disease in homeotherm (endotherm) vertebrates, except those affecting exclusively man. Fifty arboviruses pathogenic for animals have been documented worldwide, belonging to seven families: Togaviridae (mosquito-borne Eastern, Western, and Venezuelan equine encephalilitis viruses; Sindbis, Middelburg, Getah, and Semliki Forest viruses), Flaviviridae (mosquito-borne yellow fever, Japanese encephalitis, Murray Valley encephalitis, West Nile, Usutu, Israel turkey meningoencephalitis, Tembusu and Wesselsbron viruses; tick-borne encephalitis, louping ill, Omsk hemorrhagic fever, Kyasanur Forest disease, and Tyuleniy viruses), Bunyaviridae (tick-borne Nairobi sheep disease, Soldado, and Bhanja viruses; mosquito-borne Rift Valley fever, La Crosse, Snowshoe hare, and Cache Valley viruses; biting midges-borne Main Drain, Akabane, Aino, Shuni, and Schmallenberg viruses), Reoviridae (biting midges-borne African horse sickness, Kasba, bluetongue, epizootic hemorrhagic disease of deer, Ibaraki, equine encephalosis, Peruvian horse sickness, and Yunnan viruses), Rhabdoviridae (sandfly/mosquito-borne bovine ephemeral fever, vesicular stomatitis-Indiana, vesicular stomatitis-New Jersey, vesicular stomatitis-Alagoas, and Coccal viruses), Orthomyxoviridae (tick-borne Thogoto virus), and Asfarviridae (tick-borne African swine fever virus). They are transmitted to animals by five groups of hematophagous arthropods of the subphyllum Chelicerata (order Acarina, families Ixodidae and Argasidae—ticks) or members of the class Insecta: mosquitoes (family Culicidae); biting midges (family Ceratopogonidae); sandflies (subfamily Phlebotominae); and cimicid bugs (family Cimicidae). Arboviral diseases in endotherm animals may therefore be classified as: tick-borne (louping ill and tick-borne encephalitis, Omsk hemorrhagic fever, Kyasanur Forest disease, Tyuleniy fever, Nairobi sheep disease, Soldado fever, Bhanja fever, Thogoto fever, African swine fever), mosquito-borne (Eastern, Western, and Venezuelan equine encephalomyelitides, Highlands J disease, Getah disease, Semliki Forest disease, yellow fever, Japanese encephalitis, Murray Valley encephalitis, West Nile encephalitis, Usutu disease, Israel turkey meningoencephalitis, Tembusu disease/duck egg-drop syndrome, Wesselsbron disease, La Crosse encephalitis, Snowshoe hare encephalitis, Cache Valley disease, Main Drain disease, Rift Valley fever, Peruvian horse sickness, Yunnan disease), sandfly-borne (vesicular stomatitis—Indiana, New Jersey, and Alagoas, Cocal disease), midge-borne (Akabane disease, Aino disease, Schmallenberg disease, Shuni disease, African horse sickness, Kasba disease, bluetongue, epizootic hemorrhagic disease of deer, Ibaraki disease, equine encephalosis, bovine ephemeral fever, Kotonkan disease), and cimicid-borne (Buggy Creek disease). Animals infected with these arboviruses regularly develop a febrile disease accompanied by various nonspecific symptoms; however, additional severe syndromes may occur: neurological diseases (meningitis, encephalitis, encephalomyelitis); hemorrhagic symptoms; abortions and congenital disorders; or vesicular stomatitis. Certain arboviral diseases cause significant economic losses in domestic animals—for example, Eastern, Western and Venezuelan equine encephalitides, West Nile encephalitis, Nairobi sheep disease, Rift Valley fever, Akabane fever, Schmallenberg disease (emerged recently in Europe), African horse sickness, bluetongue, vesicular stomatitis, and African swine fever; all of these (except for Akabane and Schmallenberg diseases) are notifiable to the World Organisation for Animal Health (OIE, 2012).

International Energy Outlook  

Gasoline and Diesel Fuel Update (EIA)

World Oil Markets World Oil Markets In the IEO2003 forecast, periodic production adjustments by OPEC members are not expected to have a significant long-term impact on world oil markets. Prices are projected to rise gradually through 2025 as the oil resource base is further developed. Throughout most of 2002, crude oil prices were solidly within the range preferred by producers in the Organization of Petroleum Exporting Countries (OPEC), $22 to $28 per barrel for the OPEC “basket price” (see Figure 14). OPEC producers have been demonstrating disciplined adherence to announced cutbacks in production. Early in 2003, a dramatic upward turn in crude oil prices was brought about by a combination of two factors. First, a general strike against the Chavez regime resulted in a sudden drop in Venezuela’s oil exports. Although other OPEC producers agreed to increase production to make up for the lost Venezuelan output, the obvious strain on worldwide spare capacity kept prices high. Second, price volatility was exacerbated by fears of war in Iraq.

World Oil Markets World Oil Markets International Energy Outlook 2004 World Oil Markets In the IEO2004 forecast, OPEC export volumes are expected to more than double while non-OPEC suppliers maintain their edge over OPEC in overall production. Prices are projected to rise gradually through 2025 as the oil resource base is further developed. Throughout most of 2003, crude oil prices remained near the top of the range preferred by producers in the Organization of Petroleum Exporting Countries (OPEC), $22 to $28 per barrel for the OPEC “basket price.” OPEC producers continued to demonstrate disciplined adherence to announced cutbacks in production. Throughout 2003, the upward turn in crude oil prices was brought about by a combination of three factors. First, a general strike against the Chavez regime resulted in a sudden loss of much of Venezuela’s oil exports. Although the other OPEC producers agreed to increase their production capacities to make up for the lost Venezuelan output, the obvious strain on worldwide spare capacity kept prices high. Second, price volatility was exacerbated by internal conflict in Nigeria. Third, prospects for a return to normalcy in the Iraqi oil sector remained uncertain as residual post-war turmoil continued in Iraq.

Evaluation of Control Strategies to Effectively Meet 70-90% Mercury Reduction on an Eastern Bituminous Coal Cyclone Boiler with SCR  

SciTech Connect

This is the final site report for testing conducted at Public Service of New Hampshire's (PSNH) Merrimack Unit 2 (MK2). This project was funded through the DOE/NETL Innovations for Existing Plants program. It was a Phase III project with the goal to develop mercury control technologies that can achieve 50-70% mercury capture at costs 25-50% less than baseline estimates of $50,000-$70,000/lb of mercury removed. While results from testing at Merrimack indicate that the DOE goal was partially achieved, further improvements in the process are recommended. Merrimack burned a test blend of eastern bituminous and Venezuelan coals, for a target coal sulfur content of 1.2%, in its 335-MW Unit 2. The blend ratio is approximately a 50/50 split between the two coals. Various sorbent injection tests were conducted on the flue gas stream either in front of the air preheater (APH) or in between the two in-series ESPs. Initial mercury control evaluations indicated that, without SO3 control, the sorbent concentration required to achieve 50% control would not be feasible, either economically or within constraints specific to the maximum reasonable particle loading to the ESP. Subsequently, with SO{sub 3} control via trona injection upstream of the APH, economically feasible mercury removal rates could be achieved with PAC injection, excepting balance-of-plant concerns. The results are summarized along with the impacts of the dual injection process on the air heater, ESP operation, and particulate emissions.

Coating application and evaluation for heavy wall thickness, temperature and pressure pipeline  

SciTech Connect

A Venezuelan oil company is developing a project for high pressure gas injection for oil recovery. This project has a compression plant to increase the gas pressure from 1,200 to 9,000 psi. Due to the high gas pressure (9,000 psi) and high temperature (90 C), a carbon steel API 5L-X60 with 2.5 in thickness pipe has been selected. The gas is transported from the compression plant to the injection well. This type of pipeline is unique in the world and in the authors` knowledge no one has applied and evaluated external coating for this combination of heavy wall thickness, pressure and temperature pipeline. Dual fusion bonded epoxy was selected as main coating, combined with high temperature sleeves for the joints. Several parameters were considered in the selection of the coating: high temperature, wall thickness, application condition, heat during the welding process and coating performance in the lab. The large amount of heat accumulated during the application, due to the thick wall, requires a modification of coating application parameters, as well as the cooling condition. The evaluation of the coating was performed with a specially designed test for high temperatures. The laboratory results (impact resistance, degree of curing, cathodic disbonding, adhesion and hot water immersion) indicate that the application condition used was good to obtain a product under specification.

Navy Mobility Fuels Forecasting system: Phase 3, Report. [Navy  

SciTech Connect

The world oil scenarios were analyzed using the NMFFS. The linear programming models of the NMFFS have great value in the analysis of petroleum resource allocation and refining. The results of the general market analysis indicated that all disruptions resulted in reduced crude oil supply, higher prices, and reduced demand in the world. In a major Persian Gulf disruption, US refining capability appeared adequate to satisfy normal US military fuel requirements, including those supplied by foreign refiners. However, this would be at the expense of civilian fuels production. Mobilization fuel requirements during a major disruption that curtailed most Persian Gulf and Venezuelan crude exports resulted in significant competition in the production of civil versus military jet fuels, particularly in Texas Gulf Coast and West Coast refineries. In all disruption scenarios studied, the Middle East emerged as a potentially important refiner of both civil and military jet fuels. With SPR drawdown and the IEA agreements in effect, the impacts of the disruptions on the production of refined products were significantly reduced, particularly in the United States, compared to the impacts without these programs. The IEA agreement caused a redistribution of the regional demand levels among IEA countries in favor of the major oil consuming countries like the United States, Canada, and some of the European countries. The results of the RYM analysis of refinery regions focused on the availability and quality of JP-5 production in key Navy supply regions. Several findings potentially important to the Navy are listed.

Fireside carburization of stainless steel furnace tubes  

SciTech Connect

Most heavy Venezuelan crudes are recognized for having a high total acid number (TAN) that is usually associated with a high tendency to produce naphthenic acid corrosion. To resist this type of corrosion in vacuum heaters, 9Cr-1Mo steel and stainless steels containing molybdenum are usually recommended. In 1993 the original 5Cr-1/2Mo roof tubes of the furnace in a vacuum unit were replaced by stainless steel 316Ti to minimize tube replacement and increase heater reliability. Unexpectedly, some of the new tubes failed after only three years of service, and just one year after undergoing the last turnaround inspection. The damage occurred in the form of deep holes and perforations, starting from the outside tube surface on the fireside. Coke build-up occurred due to severe operating conditions, overheating the tubes on the fireside, above 675 C (1250 F). Metallographic and Scanning Electron Microscopic (SEM) examination revealed internal and external carburization of the material due to the presence of coke and combustion ashes, respectively. The increase in the skin metal temperature facilitated the diffusion of carbon from these carbon-rich deposits into the low carbon content material (0.023 O/O).Depletion of chromium at the grain boundaries due to the massive formation of chromium carbides, resulted in a severe intergranular corrosion attack by molten salts rich in vanadium and sulfur due to asphalt burning. Normal operating practice demands the use of steam for the heater tubes to control coke build-up. This practice had been first reduced and then eliminated, during the past two years prior to the failure, because of economic incentives. This paper describes the root cause analysis conducted to account for these premature tube failures.

Competitiveness of Mexican crude  

SciTech Connect

Mexico is under great pressure to maintain oil export revenue levels if it is to avoid a reversal in its economic recovery program. While the country's vulnerability to a price plunge is also applicable to OPEC countries, the North Sea producers, and others, Mexico does have an ace. The ace is that its heavier, metals-ridden and sulfur-laden Maya crude, which had to be pushed on customers until about 1981, is now in strong demand. Comparisons are presented of the market value of five crude oils refined in the US Gulf Coast: West Texas Intermediate (or WTI, a 40/sup 0/ API, light), Arabian Light and Isthmus (both 34/sup 0/ medium-light), Alaska North Slope (or ANS, a 27/sup 0/ API, a medium), and Maya (22/sup 0/ API, medium-heavy). In this mix, the heavier the crude, the greater is the refining margin (except for Arabian Light, for which freight cost and product yield provide lower margins than those derived from WTI). The sacrifice by OPEC and other producers cutting crude oil prices was to the benefit to refiners' improved margins during the first half of 1983. Those cuts were on the lighter-quality oils. But prices for heavier Venezuelan, Californian, and Mexican crudes increased during the second half of 1983, due to developing refinery technologies in extracting favorable product yields from them. This issue of Energy Detente presents their fuel price/tax series and industrial fuel prices for December 1983 for countries of the Western Hemisphere.

Impact and future of heavy oil produciton  

SciTech Connect

Heavy oil resources are becoming increaingly important in meeting world oil demand. Heavy oil accounts for 10% of the worlds current oil production and is anticipated to grow significantly. Recent narrowing of the price margins between light and heavy oil and the development of regional heavy oil markets (production, refining and marketing) have prompted renewed investment in heavy oil. Production of well known heavy oil resources of Canada, Venezuela, United States, and elsewhere throughout the world will be expanded on a project-by-project basis. Custom refineries designed to process these heavy crudes are being expanded. Refined products from these crudes will be cleaner than ever before because of the huge investment. However, heavy oil still remains at a competitive disadvantage due to higher production, transportation and refining have to compete with other investment opportunities available in the industry. Expansion of the U.S. heavy oil industry is no exception. Relaxation of export restrictions on Alaskan North Slope crude has prompted renewed development of California's heavy oil resources. The location, resource volume, and oil properties of the more than 80-billion barrel U.S. heavy oil resource are well known. Our recent studies summarize the constraints on production, define the anticipated impact (volume, location and time frame) of development of U.S. heavy oil resources, and examines the $7-billion investment in refining units (bottoms conversion capacity) required to accommodate increased U.S. heavy oil production. Expansion of Canadian and Venezuelan heavy oil and tar sands production are anticipated to dramatically impact the U.S. petroleum market while displacing some imported Mideast crude.

Liquid fossil fuel technology. Quarterly technical progress report, January-March 1980  

SciTech Connect

Highlights of the BETC January-March 1980 quarter were: Gasohol was tested in a cooperative effort with Southwestern Bell Telephone Co. Two fleets of 55 cars were tested using gasohol in one and gasoline in the other. No problems were encountered. The gasohol-fueled cars had less emissions, and the fuel efficiencies for both fleets were approximately the same. An in situ combustion has been successfully started in a heavy oil deposit in Kansas. After some difficulties in starting the burn, it is now operating satisfactorily and producing oil. Cooperation between DOE and the Venezuelan oil industry was explored in a meeting at BETC that emphasized efforts to produce heavy oil. Cooperation through the International Energy Agency is expected to result in sharing of technology on enhanced oil recovery. Petroleum product surveys are produced cooperatively by DOE and the American Petroleum Institute. They give the properties of the products currently being marketed in the US. During the quarter, surveys on Motor Gasolines, Summer 1979 and Diesel Fuel Oils, 1979 were published. They are used to trace changes in characteristics and also to set specifications. The size of colloids, micelles, and emulsions in petroleum and associated liquids can be a factor in the design of improved recovery processes. The use of small angle x-ray scattering has been facilitated by a new method of calculation. The development of the Liquid Fossil Fuel Cycle has been facilitated by a workshop and further discussions resulting in a new statement Planning Framework for Liquid Fossil Fuel Cycle, March 1, 1980. This has now been used to prepare a computer-processible form to use in a critical path study of the BETC program.

Effect of modifying host oil on coprocessing  

SciTech Connect

The world`s supply of petroleum crudes is becoming heavier in nature so that the amount of vacuum bottoms has been steadily increasing. Coprocessing of coal with these resids (1,000 F+) is an attractive way of obtaining useful distillates from these readily available cheap materials. The objective of this work is to pretreat the host oil in ways that would improve its performance in coprocessing with coal. The following are examples of some ways in which heavy oil could be made into a better host oil: converting aromatic structures to hydroaromatics capable of donating hydrogen to coal, cracking the heavy oil to lower molecular weight material that would be a better solvent, and removing metals, sulfur, and nitrogen. The work reported here used a Venezuelan oil obtained from the Corpus Christi refinery of Citgo. Two coals, Illinois No. 6 and Wyodak subbituminous, were coprocessed with host oils. The authors have found that mild pretreatment of a Citgo resid (1,000 F) using either Mo naphthenate or Mo/Fe{sub 2}O{sub 3}/SO{sub 4}, as well as a pretreatment using the homogeneous catalyst Co{sub 2}(CO){sub 8} under synthesis gas can increase the available (donatable) hydrogen content of the resid. When these pretreated oils were thermally (no added catalyst) coprocessed with an Illinois No. 6 coal, about 90 wt% of the coal (maf) was converted to soluble products. This high coal conversion was realized even at a high coal loading of 50 wt%. The products from coprocessing coal and oil were equally split between high boiling material, mostly asphaltenes, and distillate. Distillate yields appeared to be affected by the concentration of coal in the feed, with maximum yields at coal loadings below 50 wt%.
