    A previously idle portion of the Midway-Sunset field, the ARCO Western Energy Pru Fee property, is being brought back into commercial production through tight integration of geologic characterization, geostatistical modeling, reservoir simulation, and petroleum engineering. This property, shut-in over a decade ago as economically marginal using conventional cyclic steaming methods, has a 200-300 foot thick oil column in the Monarch Sand. However, the sand lacks effective steam barriers and has a thick water-saturation zone above the oil-water contact. These factors require an innovative approach to steam flood production design that will balance optimal total oil production against economically viable steam-oil ratios and production rates. The methods used in the Class III demonstration are accessible to most operators in the Midway-Sunset field and could be used to revitalize properties with declining production of heavy oils throughout the region. In January 1997 the project entered its second and main phase with the purpose of demonstrating whether steamflood can be a more effective mode of production of the heavy, viscous oils from the Monarch Sand reservoir than the more conventional cyclic steaming. The objective is not just to produce the pilot site within the Pru Fee property south of Taft, but to test which production parameters optimize total oil recovery at economically acceptable rates of production and production costs.

    This project reactivates ARCO`s idle Pru Fee lease in the Midway-Sunset field, California and conducts a continuous steamflood enhanced oil recovery demonstration aided by an integration of modern reservoir characterization and simulation methods. Cyclic steaming is being used to reestablish baseline production within the reservoir characterization phase of the project. During the demonstration phase scheduled to begin in January 1997, a continuous steamflood enhanced oil recovery will be initiated to test the incremental value of this method as an alternative to cyclic steaming. Other economically marginal Class III reservoirs having similar producibility problems will benefit from insight gained in this project. The objectives of the project are: (1) to return the shut-in portion of the reservoir to optimal commercial production; (2) to accurately describe the reservoir and recovery process; and (3) to convey the details of this activity to the domestic petroleum industry, especially to other producers in California, through an aggressive technology transfer program.

    During the initial phase of the project a multifaceted feasibility study was carried out to examine whether the pilot project could be justified technically and economically at this site. This study included: (1) Recompletion of 9 shut-in wells and drilling of a additional producer and a new temperature observation well. A core was taken from the reservoir interval in the new producer, Pru-101. The wells were produced by conventional cyclic steaming over a period of 15 months to establish a production baseline for the site, (2) Characterization of the stratigraphy and petrophysical properties of the Monarch Sand reservoir using existing well logs and analyses on samples in the core taken from Pru-101. The resulting data were used to develop a geostatistical model of the reservoir at the Pru Fee property and a specific reservoir simulator for the pilot test site on the property, and (3) Use of the reservoir simulator to test various steamflood and cyclic steaming production options leading to design of a production strategy for the pilot steamflood based on a four pattern, 9-spot array covering 8 ac near the center of the 40 ac Pru Fee property. The array chosen required drilling additional producers and injectors to supplement the existing wells recompleted in the initial phase of the project.

  14. Heavy oil upgrading via fluidized bed processing and hydrogenation processing

    Dawson, F.N. Jr.

    1995-09-01

    California is the second largest crude oil producer in the lower 48 states. Nearly half of its production is heavy oil, difficult to transport and costly to refine. Given better methods of processing, production could be expanded. Likewise, huge worldwide reserves of heavy oils could be better exploited if more attractive processing methods were available. Midway Sunset crude at 11.8 API gravity, is a fairly difficult crude to process. It has about 1.5 percent sulfur, a very high nitrogen content, in the range of 0.7--0.8%, and metals of approximately 120--170 ppm, vanadium plus nickel. The authors will be reporting here results of the pilot plant testing to see whether non-catalytic fluid bed cracking technology, operated at low conversion, followed by hydrogenation would be economically attractive. Results suggest that this approach is competitive with delayed coking and with atmospheric resid desulfurization. This approach successfully combines carbon removal and hydrogen addition techniques for heavy oil upgrading. Comparative yields, product quality and economic considerations are reviewed in this study.

    Midway Sunset crude oil and well-head oil were treated at elevated temperatures in a closed system with the presence of water. Mild to moderate upgrading, as measured by increase in API gravity, was observed at 400{degrees}C or above. Reduced pressure operation exhibited upgrading activity comparable to upgrading under normal aqueous pyrolysis conditions. Reduced pressure operation was obtained by the use of specific blending methods, a surfactant, and the proper amount of water. The use of additives provided additional upgrading. The best of the minimum set tested was Co(II) 2-ethylhexanoate. Fe(III) 2-ethylhexanoate also showed some activity under certain conditions.

    Midway Valley, located at the eastern base of the Yucca Mountain in southwestern Nevada, is the preferred location of the surface facilities for the potential high-level nuclear waste repository at Yucca Mountain. One goal in siting these surface facilities is to avoid faults that could produce relative displacements in excess of 5 cm in the foundations of the waste-handling buildings. This study reviews existing geologic and geophysical data that can be used to assess the potential for surface fault rupture within Midway Valley. Dominant tectonic features in Midway Valley are north-trending, westward-dipping normal faults along the margins of the valley: the Bow Ridge fault to the west and the Paintbrush Canyon fault to the east. Published estimates of average Quaternary slip rates for these faults are very low but the age of most recent displacement and the amount of displacement per event are largely unknown. Surface mapping and interpretive cross sections, based on limited drillhole and geophysical data, suggest that additional normal faults, including the postulated Midway Valley fault, may exist beneath the Quaternary/Tertiary fill within the valley. Existing data, however, are inadequate to determine the location, recency, and geometry of this faulting. To confidently assess the potential for significant Quaternary faulting in Midway Valley, additional data are needed that define the stratigraphy and structure of the strata beneath the valley, characterize the Quaternary soils and surfaces, and establish the age of faulting. The use of new and improved geophysical techniques, combined with a drilling program, offers the greatest potential for resolving subsurface structure in the valley. Mapping of surficial geologic units and logging of soil pits and trenches within these units must be completed, using accepted state-of-the-art practices supported by multiple quantitative numerical and relative age-dating techniques.

    Highlights: NiS/TiO{sub 2} was successfully synthesized by solgel method. This new method of preparation gives a homogeneous dispersion of NiS on TiO{sub 2}. Degradation activity of NiS/TiO{sub 2} is found to be more efficient than other catalysts. Addition of oxidants enhances the degradation efficiency significantly. COD measurements reveal the complete mineralization of dye molecules. The catalyst is found to be reusable. - Abstract: To improve the solar light induced photocatalytic application performances of TiO{sub 2}, in this study, the NiS modified TiO{sub 2} composite photocatalysts with various ratios of NiS to TiO{sub 2} were prepared by solgel method. The catalyst was characterized by X-ray diffraction (XRD), high resolution scanning electron microscope (HR-SEM), high resolution transmission electron microscope (HR-TEM), energy dispersive spectra (EDS), diffuse reflectance spectra (DRS), photoluminescence spectra (PL), X-ray photoelectron spectroscopy (XPS), and BrunauerEmmettTeller (BET) surface area measurement methods. The photocatalytic activity of NiS/TiO{sub 2} was investigated for the degradation of sunset yellow (SY) in aqueous solution using solar light. The NiS/TiO{sub 2} is found to be more efficient than prepared TiO{sub 2} and TiO{sub 2}P25 at pH 7 for the mineralization of SY. The effects of operational parameters such as the amount of photocatalyst, dye concentration and initial pH on photo mineralization of SY have been analyzed. The degradation was strongly enhanced in the presence of oxidants such as H{sub 3}K{sub 5}O{sub 18}S{sub 4} (Oxone), KIO{sub 4}, and KBrO{sub 3}. The mineralization of SY has been identified by COD measurements. The catalyst is found to be reusable.

    The Utah Heavy Oil Program (UHOP) was established in June 2006 to provide multidisciplinary research support to federal and state constituents for addressing the wide-ranging issues surrounding the creation of an industry for unconventional oil production in the United States. Additionally, UHOP was to serve as an on-going source of unbiased information to the nation surrounding technical, economic, legal and environmental aspects of developing heavy oil, oil sands, and oil shale resources. UHOP fulGilled its role by completing three tasks. First, in response to the Energy Policy Act of 2005 Section 369(p), UHOP published an update report to the 1987 technical and economic assessment of domestic heavy oil resources that was prepared by the Interstate Oil and Gas Compact Commission. The UHOP report, entitled 'A Technical, Economic, and Legal Assessment of North American Heavy Oil, Oil Sands, and Oil Shale Resources' was published in electronic and hard copy form in October 2007. Second, UHOP developed of a comprehensive, publicly accessible online repository of unconventional oil resources in North America based on the DSpace software platform. An interactive map was also developed as a source of geospatial information and as a means to interact with the repository from a geospatial setting. All documents uploaded to the repository are fully searchable by author, title, and keywords. Third, UHOP sponsored Give research projects related to unconventional fuels development. Two projects looked at issues associated with oil shale production, including oil shale pyrolysis kinetics, resource heterogeneity, and reservoir simulation. One project evaluated in situ production from Utah oil sands. Another project focused on water availability and produced water treatments. The last project considered commercial oil shale leasing from a policy, environmental, and economic perspective.

    The Heavy Duty Truck Engine Program at Cummins embodied three significant development phases. All phases of work strove to demonstrate a high level of diesel engine efficiency in the face of increasingly stringent emission requirements. Concurrently, aftertreatment system development and refinement was pursued in support of these efficiency demonstrations. The program's first phase focused on the demonstration in-vehicle of a high level of heavy duty diesel engine efficiency (45% Brake Thermal Efficiency) at a typical cruise condition while achieving composite emissions results which met the 2004 U.S. EPA legislated standards. With a combination of engine combustion calibration tuning and the development and application of Urea-based SCR and particulate aftertreatment, these demonstrations were successfully performed by Q4 of 2002. The second phase of the program directed efforts towards an in-vehicle demonstration of an engine system capable of meeting 2007 U.S. EPA legislated emissions requirements while achieving 45% Brake Thermal Efficiency at cruise conditions. Through further combustion optimization, the refinement of Cummins Cooled EGR architecture, the application of a high pressure common rail fuel system and the incorporation of optimized engine parasitics, Cummins Inc. successfully demonstrated these deliverables in Q2 of 2004. The program's final phase set a stretch goal of demonstrating 50% Brake Thermal Efficiency from a heavy duty diesel engine system capable of meeting 2010 U.S. EPA legislated emissions requirements. Cummins chose to pursue this goal through further combustion development and refinement of the Cooled EGR system architecture and also applied a Rankine cycle Waste Heat Recovery technique to convert otherwise wasted thermal energy to useful power. The engine and heat recovery system was demonstrated to achieve 50% Brake Thermal Efficiency while operating at a torque peak condition in second quarter, 2006. The 50% efficient engine system was capable of meeting 2010 emissions requirements through the application of NOx and particulate matter reduction techniques proven earlier in the program.

    1959-01-01

    A linear accelerator of heavy ions is described. The basic contributions of the invention consist of a method and apparatus for obtaining high energy particles of an element with an increased charge-to-mass ratio. The method comprises the steps of ionizing the atoms of an element, accelerating the resultant ions to an energy substantially equal to one Mev per nucleon, stripping orbital electrons from the accelerated ions by passing the ions through a curtain of elemental vapor disposed transversely of the path of the ions to provide a second charge-to-mass ratio, and finally accelerating the resultant stripped ions to a final energy of at least ten Mev per nucleon.

  10. Advances in heavy oil hydroprocessing

    1988-06-01

    The world increase in heavy crudes has forced refiners to develop different processes that upgrade the yields and product properties recovered from these crudes. However, some of the optimized and new processes are not able to handle whole heavy crude oils, due to the high viscosity and corrosion of their long and short residues. The different processes for heavy crudes can be classified in two areas: physical (vg. Liquid Extraction) and chemical processes. The catalytic hydrotreating process, which belongs to this last classification, has demonstrated to be an economical upgrading process for heavy crude oil. This paper describes the development by the Mexican Petroleum Institute of the process to hydrotreat maya heavy crude. The effect of the operating conditions, the catalyst ---- development and the technical - economical analysis are presented. The product properties and yields are compared with the results obtained with light crude oil like isthmus.

  13. Upgrading of heavy hydrocarbonaceous feeds

    SciTech Connect (OSTI)

    Bhattacharya, A.K.; Storm, D.A.; DeRosa, T.F.

    1995-12-31

    This paper is based on our work in the area of upgrading of heavy hydrocarbonaceous feedstocks. The work involves the development of a method of catalytically hydroconverting a hydrocarbon feed stream containing a substantial quantity of components boiling above about 538{degrees}C to a substantial portion thereof to components boiling below 538{degrees}C. More particularly, an oil-miscible or oil-soluble poly(ether)diol or a derivative thereof and an aromatic additive oil, such as Heavy Cycle Gas oil, are added to a heavy hydrocarbon feed and the mixed stream is contacted at elevated temperatures with a solid catalyst such as a sulfided nickel molybdenum oxide on alumina in the presence of hydrogen under pressure. This method advantageously affords higher conversion to more valuable liquid products containing lower amounts of heteroatoms such as sulfur, substantially eliminates plugging of the hydroconversion reactor, and reduces the amount of insolubles in the total liquid product.

    1982-09-01

    The Orinoco Heavy Oil Belt of Venezuela is a subsurface geological formation of petroleum-bearing sands that is approximately 700 km long and between 60 and 80 km wide. The results of recent explorations have shown the area to contain over one trillion barrels of oil in-place, ranging from 8/sup 0/ API to 14/sup 0/ APE gravity. In an effort to develop these resources, Petroleos de Venezuela has undertaken a program to evaluate and develop this heavy oil belt. The objectives of this program are discussed along with the process technology selection, pilot plants, and environmental protection measures. (JMT)

The development of cleaner, higher-efficiency diesel engines imposes greater mechanical, thermal, and tribological demands on materials of construction. Often the enabling technology for a new engine component is the material from which the part can be made. The Heavy Vehicle Propulsion Materials Program is a partnership between the Department of Energy (DOE), and the diesel engine companies in the United States, materials suppliers, national laboratories, and universities. A comprehensive research and development program has been developed to meet the enabling materials requirements for the diesel engines of the future. Advanced materials, including high-temperature metal alloys, intermetallics, cermets, ceramics, amorphous materials, metal- and ceramic-matrix composites, and coatings, are investigated for critical engine applications.

    1996-10-01

    The hydrogen-donating properties of some hydrocarbons form the basis for processes such as coal liquefaction and heavy oil upgrading. However, these hydrocarbons have seldom been used for other purposes, because their potential applications have not been well recognized. Research has indicated that these hydrogen-donating hydrocarbons can be used in important reactions as radical scavengers and have properties particular to those of pure hydrocarbons without functional groups containing heteroatoms. Over years of study researchers have found that pure hydrocarbons with radical-scavenging effects nearly as high as those in conventional hindered phenolic antioxidants can be produced from petroleum, and these hydrogen-donating hydrocarbons exhibit such effects even in oxidative atmospheres (i.e., they function as antioxidants). He has also shown that these mixtures have some properties particular to pure hydrocarbons without functional groups containing heteroatoms, and they`ve seen that a mechanism based on the steric effects appears when these hydrocarbons are used in heavy oil hydroprocessing. Hydrogen-donating hydrocarbons should be a viable resource in many applications. In this article, he presents radical-scavenging abilities, characteristics as pure hydrocarbons, and applications on the basis of the studies.

    This report describes work performed for an Early Career Research and Development project. This project developed a heavy-duty vehicle (HDV) sector model to assess the factors influencing alternative fuel and efficiency technology adoption. This model builds on a Sandia light duty vehicle sector model and provides a platform for assessing potential impacts of technological advancements developed at the Combustion Research Facility. Alternative fuel and technology adoption modeling is typically developed around a small set of scenarios. This HDV sector model segments the HDV sector and parameterizes input values, such as fuel prices, efficiencies, and vehicle costs. This parameterization enables sensitivity and trade space analyses to identify the inputs that are most associated with outputs of interest, such as diesel consumption and greenhouse gas emissions. Thus this analysis tool enables identification of the most significant HDV sector drivers that can be used to support energy security and climate change goals.

    Brodsky, S.J.

    1985-09-01

    For very large pair mass, the production of heavy quarks and supersymmetric particles is expected to be governed by ACD fusion subprocesses. At lower mass scales other QCD mechanisms such as prebinding distortion and intrinsic heavy particle Fock states can become important, possibly accounting for the anomalies observed for charm hadroproduction. We emphasize the importance of final-state Coulomb interactions at low relative velocity in QCD and predict the existence of heavy narrow four quark resonances (c c-bar u u-bar) and (cc c-bar c-bar) in ..gamma gamma.. reactions. Coherent QCD contributions are discussed as a contribution to the non-additivity of nuclear structure functions and heavy particle production cross sections. We also predict a new type of amplitude zero for exclusive heavy meson pair production which follows from the tree-graph structure of QCD. 35 refs., 8 figs., 1 tab.

    Brodsky, S.J.

    1991-04-01

    Heavy quarks can expose new symmetries and novel phenomena in QCD not apparent in ordinary hadronic systems. In these lectures I discuss the use of effective-Lagrangian and light-cone Fock methods to analyze exclusive heavy hadron decays such as {Upsilon} {yields} p{bar p} and B {yields} {pi}{pi}, and also to derive effective Schroedinger and Dirac equations for heavy quark systems. Two contributions to the heavy quark structure functions of the proton and other light hadrons are identified: an extrinsic'' contribution associated with leading twist QCD evolution of the gluon distribution, and a higher twist intrinsic'' contribution due to the hardness of high-mass fluctuations of multi-gluon correlations in hadronic wavefunctions. A non-perturbative calculation of the heavy quark distribution of a meson in QCD in one space and one time is presented. The intrinsic higher twist contributions to the pion and proton structure functions can dominate the hadronic production of heavy quark systems at large longitudinal momentum fraction x{sub F} and give anomalous contributions to the quark structure functions of ordinary hadrons at large x{sub bj}. I also discuss a number of ways in which heavy quark production in nuclear targets can test fundamental QCD phenomena and provide constraints on hadronic wavefunctions. The topics include color transparency, finite formation time, and predictions for charm production at threshold, including nuclear-bound quarkonium. I also discuss a number of QCD mechanisms for the suppression of J/{psi} and {Upsilon} production in nuclear collisions, including gluon shadowing, the peripheral excitation of intrinsic heavy quark components at large x{sub F}, and the coalescence of heavy quarks with co-moving spectators at low x{sub F}.

Their low temperature properties are characterized by an electronic energy scale of order 1--10 K. Among the low temperature ground states observed in heavy Fermion compounds are exotic superconductors and magnets, as well as unusual semiconductors.

    Crude oil occurs in many different forms throughout the world. An important characteristic of crude oil that affects the ease with which it can be produced is its density and viscosity. Lighter crude oil typically can be produced more easily and at lower cost than heavier crude oil. Historically, much of the nation's oil supply came from domestic or international light or medium crude oil sources. California's extensive heavy oil production for more than a century is a notable exception. Oil and gas companies are actively looking toward heavier crude oil sources to help meet demands and to take advantage of large heavy oil reserves located in North and South America. Heavy oil includes very viscous oil resources like those found in some fields in California and Venezuela, oil shale, and tar sands (called oil sands in Canada). These are described in more detail in the next chapter. Water is integrally associated with conventional oil production. Produced water is the largest byproduct associated with oil production. The cost of managing large volumes of produced water is an important component of the overall cost of producing oil. Most mature oil fields rely on injected water to maintain formation pressure during production. The processes involved with heavy oil production often require external water supplies for steam generation, washing, and other steps. While some heavy oil processes generate produced water, others generate different types of industrial wastewater. Management and disposition of the wastewater presents challenges and costs for the operators. This report describes water requirements relating to heavy oil production and potential sources for that water. The report also describes how water is used and the resulting water quality impacts associated with heavy oil production.

    This report is the final report for the Department of Energy on the Heavy Truck Engine Program (Contract No. DE-FC05-00OR22806) also known as Heavy Truck Clean Diesel (HTCD) Program. Originally, this was scoped to be a $38M project over 5 years, to be 50/50 co-funded by DOE and Caterpillar. The program started in June 2000. During the program the timeline was extended to a sixth year. The program completed in December 2006. The program goal was to develop and demonstrate the technologies required to enable compliance with the 2007 and 2010 (0.2g/bhph NOx, 0.01g/bhph PM) on-highway emission standards for Heavy Duty Trucks in the US with improvements in fuel efficiency compared to today's engines. Thermal efficiency improvement from a baseline of 43% to 50% was targeted.

  2. Process for upgrading a heavy viscous hydrocarbon

    Lutz, I.H.

    1984-06-12

    A process for upgrading a heavy viscous hydrocarbon, for example, rendering a heavy viscous crude pipelinable, includes visbreaking, distillation and solvent extraction steps. A heavy viscous hydrocarbon is fed through the visbreaker which forms a feed to the distillation step. A heavier fraction from distillation is fed to a solvent extraction unit which produces a fraction which contains resin. At least a portion of the resin containing fraction separated in the solvent extraction unit is recycled and combined with the feed which is to be subjected to visbreaking so that the total yield of products, residual and gas-free, is increased. The recycled resin reduces the tendency of the asphaltenes to separate from the oil and thereby reduces the tendency to lay down coke in the visbreaker; this allows higher conversion to upgraded liquid products.

    1988-01-01

    A number of studies have been reported on coprocessing of coal and oil sand bitumen, petroleum residues and distillate fractions in catalytic and non-catalytic processes. The studies described the effects of feedstock characteristics, process chemistry and operating variables on the product yield and distribution; however, very few kinetic data were reported in these investigations. This paper presents the kinetic data and modeling of the CANMET coal/heavy oil coprocessing process. A number of reaction networks were evaluated for CANMET coprocessing. The final choice of model was a parallel model with some sequential characteristics. The model explained 90.0 percent of the total variance, which was considered satisfactory in view of the difficulties of modeling preasphaltenes. The models which were evaluated showed that the kinetic approach successfully applied to coal liquefaction and heavy oil upgrading can be also applied to coprocessing. The coal conversion networks and heavy oil upgrading networks are interrelated via the forward reaction paths of preasphaltenes, asphaltenes, and THFI and via the reverse kinetic paths of an adduct formation between preasphaltenes and heavy oil.

  8. Hydroprocessing catalysts for heavy oil and coal

    Satriana, M.J.

    1982-01-01

    Hydroprocessing catalysts, as described in over 230 processes covered in this book, are hydrogenation catalysts used in the upgrading of heavy crudes and coal to products expected to be in great demand as the world's primary oil supplies gradually dwindle. The techniques employed in hydroprocessing result in the removal of contaminants, the transformation of lower grade materials such as heavy crudes to valuable fuels, or the conversion of hydrocarbonaceous solids into gaseous or liquid fuel products. All of these techniques are, of course, carried out in the presence of hydrogen. Some of the brightest energy prospects for the future lie in heavy oil reservoirs and coal reserves. Heavy oils, defined in this book as having gravities of < 20/sup 0/API, are crudes so thick that they are not readily extracted from their reservoirs. However, processing of these crudes is of great importance, because the US resource alone is enormous. The main types of processing catalysts covered in the book are hydrorefining catalysts plus some combinations of the two. Catalysts for the conversion of hydrocarbonaceous materials to gaseous or liquid fuels are also covered. The primary starting material for these conversions is coal, but wood, lignin, oil shale, tar sands, and peat are other possibilities. The final chapter describes the preparation of various catalyst support systems.

    1997-01-01

    Three aspects of supersymmetric theories are discussed: electroweak symmetry breaking, the issues of flavor, and gauge unification. The heavy top quark plays an important, sometimes dominant, role in each case. Additional symmetries lead to extensions of the Standard Model which can provide an understanding for many of the outstanding problems of particle physics. A broken supersymmetric extension of spacetime allows electroweak symmetry breaking to follow from the dynamics of the heavy top quark; an extension of isospin provides a constrained framework for understanding the pattern of quark and lepton masses; and a grand unified extension of the Standard Model gauge group provides an elegant understanding of the gauge quantum numbers of the components of a generation. Experimental signatures for each of these additional symmetries are discussed.

    As part of the search for a phase transition or critical point on the QCD phase diagram, an energy scan including 5 different energy settings was performed during the 2010 RHIC heavy ion run. While the top beam energy for heavy ions is at 100 GeV/n and the lowest achieved energy setpoint was significantly below RHICs injection energy of approximately 10 GeV/n, we also provided beams for data taking in a medium energy range above injection energy and below top beam energy. This paper reviews RHIC experience and challenges for RHIC medium energy operations that produced full experimental data sets at beam energies of 31.2 GeV/n and 19.5 GeV/n. The medium energy AuAu run covered two beam energies, both above the RHIC injection energy of 9.8 GeV but well below the standard store energy of 100 GeV (see table 1). The low energy and full energy runs with heavy ions in FY10 are summarized in [1] and [2]. Stochastic Cooling ([3]) was only used for 100 GeV beams and not used in the medium energy run. The efficiency of the transition from 100 GeV operation to 31.2 GeV and then to 19.5 GeV was remarkable. Setup took 32 h and 19 h respectively for the two energy settings. The time in store, defined to be the percentage of time RHIC provides beams in physics conditions versus calendar time, was approximately 52% for the entire FY10 heavy ion run. In both medium energy runs it was well above this average, 68% for 31.5 GeV and 82% for 19.5 GeV. For both energies RHIC was filled with 111 bunches with 1.2 10{sup 9} and 1.3 10{sup 9} ions per bunch respectively.

    A method is described for reducing the coking tendency of a heavy hydrocarbon feedstock in a non-hydrogenative catalytic cracking process. The process comprises contacting the feedstock prior to catalytic cracking with a free radical removing catalyst comprising a transition metal napthenate at a temperature below 350/sup 0/C. for a time sufficient to reduce the free radical concentration of the feedstock whereby the coking tendency of the feedstock to the catalytic cracking process is reduced.

  8. Upgrading heavy oil using slurry processes

    Del Bianco, A.; Panariti, N.; Marchionna, M.

    1995-11-01

    There is a growing interest in processes capable of converting heavy feedstocks (petroleum residues and heavy oils) into lower boiling products of high quality. The operational problems of upgrading heavy feeds relate to the presence of sulfur, nitrogen, metals, and considerable amounts of Conradson carbon residue. An efficient residue conversion process must be able to reduce the molecular weight of the feedstocks to material with boiling points below 550 C, increase the H-to-C ratio of the refined product, and remove heteroatoms and metals. Whereas the molecular weight reduction is normally achieved by C-C bond cracking above 400 C, often in the presence of acid catalysts, a higher H-to-C ratio can be obtained by either the rejection of carbon (as in coking) or the addition of hydrogen (as in hydrogenation processes). Slurry processes combine the flexibility of the carbon rejection with the high performance of the hydrogen addition processes. The origin of slurry processes is the Bergius-Pier technology (1920--1930) for the conversion of heavy oils and coal into distillates. Whereas the original Bergius-Pier technology did not use a catalyst, small amounts of inexpensive additives or finely dispersed hydrogenation catalysts can be used to increase the rates of the desired reactions. Catalysts can also inhibit coke formation by physically interfering with the coalescence of mesophase, which is the precursor of solid coke. Catalysts are used to reduce the severity of the process and to improve the quality of the products. Most of the research carried out in the past decade in the field of slurry processes has dealt with the identification of more effective and/or less expensive catalysts and the technological problems related to their use. Here the authors discuss both subjects, describing the path from the fundamental chemistry of dispersed catalytic systems to the development and initial commercialization of slurry processes.

  9. Co-processing of heavy oil

    SciTech Connect (OSTI)

    Khan, M.R.

    1995-12-31

    In co-processing of petroleum and coal, the petroleum fraction may serve as the {open_quotes}liquefaction solvent,{close_quotes} or hydrogen donor, and the aromatics present in the coal liquid may serve as hydrogen {open_quotes}shuttlers{close_quotes} by efficiently transferring hydrogen moieties to places where they are most deficient. The important advantages of co-processing include the following: (1) upgrading of heavy petroleum in a reaction with coal and (2) conversion of coal to synthetic crudes which could be further upgraded to a premium liquid fuel. Co-processing of coal with petroleum, heavy crudes, and residues through catalytic hydrogenation or solvent extraction have been extensively investigated. The studies were typically conducted in the temperature range of 450{degrees}-500{degrees}C under pressurized hydrogen; catalysts are generally also added for hydroconversion of the feedstocks. However, relatively little has been reported in the literature regarding co-processing of coal with heavy petroleum by simple pyrolysis. In this study, co-processing of heavy oil and coal at relatively middle conditions was conducted without the complicating influences of pressurized hydrogen or catalysts. The resulted demonstrate that there is a synergism during co-processing of petroleum and coal. This synergism enhances both the yield and quality of the liquid products. In general, liquids from co-processing the mixture contain a higher content of alkane/alkene, neutral aromatics, lower content of monophenols, and other oxygen containing compounds as compared to the liquids from coal alone. The liquid from the mixture also contains a higher content of naphthenic carbon and naphthenic rings/molecules than those from coal liquid. This suggests that the product from the mixture can be easily upgraded to a premium quality fuel.

For example, oil companies have proposed improved methods for converting natural gas to zero-aromatics, zero-sulfur diesel fuel via the Fischer-Tropsch process. Major heavy-duty diesel engine companies are working on ways to simultaneously reduce particulate-matter and NOX emissions. The trend in heavy vehicles is toward use of lightweight materials, tires with lower rolling resistance, and treatments to reduce aerodynamic drag. In this paper, we compare the Mecycle energy use and emissions from trucks using selected alternatives, such as Fisher-Tropsch diesel fuel and advanced fuel-efficient engines. We consider heavy-duty, Class 8 tractor-semitrailer combinations for this analysis. The total life cycle includes production and recycling of the vehicle itself, extraction, processing, and transportation of the fuel itself, and vehicle operation and maintenance. Energy use is considered in toto, as well as those portions that are imported, domestic, and renewable. Emissions of interest include greenhouse gases and criteria pollutants. Angonne's Greenhouse Gases, Regulated Emissions, and Energy Use in Transportation (GREET) model is used to generate per-vehicle fuel cycle impacts. Energy use and emissions for materials manufacturing and vehicle disposal are estimated by means of materials information from Argonne studies. We conclude that there are trade-offs among impacts. For example, the lowest fossil energy use does not necessarily result in lowest total energy use, and lower tailpipe emissions may not necessarily result in lower lifecycle emissions of all criteria pollutants.

It consists in the simultaneous analysis of X-rays induced in the sample and in a secondary target arranged behind the specimen. The X-rays originated in the secondary target are attenuated when crossing the specimen producing a radiographic image with a monochromatic source.

    We introduce and explore new heavy Higgs scenarios in the Minimal Supersymmetric Standard Model (MSSM) with explicit CP violation, which have important phenomenological implications that may be testable at the LHC. For soft supersymmetry-breaking scales MS above a few TeV and a charged Higgs boson mass MH+ above a few hundred GeV, new physics effects including those from explicit CP violation decouple from the light Higgs boson sector. However, such effects can significantly alter the phenomenology of the heavy Higgs bosons while still being consistent with constraints from low-energy observables, for instance electric dipole moments. To consider scenarios with amore » charged Higgs boson much heavier than the Standard Model (SM) particles but much lighter than the supersymmetric particles, we revisit previous calculations of the MSSM Higgs sector. We compute the Higgs boson masses in the presence of CP violating phases, implementing improved matching and renormalization-group (RG) effects, as well as two-loop RG effects from the effective two-Higgs Doublet Model (2HDM) scale MH± to the scale MS. Here, we illustrate the possibility of non-decoupling CP-violating effects in the heavy Higgs sector using new benchmark scenarios named.« less

    One approach being explored as a route to practical fusion energy uses heavy ion beams focused on an indirect drive target. Such beams will lose electrons while passing through background gas in the target chamber, and therefore it is necessary to assess the rate at which the charge state of the incident beam evolves on the way to the target. Accelerators designed primarily for nuclear physics or high energy physics experiments utilize ion sources that generate highly stripped ions in order to achieve high energies economically. As a result, accelerators capable of producing heavy ion beams of 10 to 40 Mev/amu with charge state 1 currently do not exist. Hence, the stripping cross-sections used to model the performance of heavy ion fusion driver beams have, up to now, been based upon theoretical calculations. We have investigated experimentally the stripping of 3.4 Mev/amu Kr 7+ and Xe +11 in N2; 10.2 MeV/amu Ar +6 in He, N2, Ar and Xe; 19 MeV/amu Ar +8 in He, N2, Ar and Xe; 30 MeV He 1 + in He, N2, Ar and Xe; and 38 MeV/amu N +6 in He, N2, Ar and Xe. The results of these measurements are compared with the theoretical calculations to assess their applicability over a wide range of parameters.

    We employ a mean-field theory to study ground-state properties and transport of a two-dimensional gas of ultracold alkaline-earth-metal atoms governed by the Kondo lattice Hamiltonian plus a parabolic confining potential. In a homogenous system, this mean-field theory is believed to give a qualitatively correct description of heavy-fermion metals and Kondo insulators: It reproduces the Kondo-like scaling of the quasiparticle mass in the former and the same scaling of the excitation gap in the latter. In order to understand ground-state properties in a trap, we extend this mean-field theory via local-density approximation. We find that the Kondo insulator gap manifests as a shell structure in the trapped density profile. In addition, a strong signature of the large Fermi surface expected for heavy-fermion systems survives the confinement and could be probed in time-of-flight experiments. From a full self-consistent diagonalization of the mean-field theory, we are able to study dynamics in the trap. We find that the mass enhancement of quasiparticle excitations in the heavy-Fermi liquid phase manifests as slowing of the dipole oscillations that result from a sudden displacement of the trap center.

    Characterization of abundant ''heavy'' feedstocks such as tar sands, heavy oils and vacuum residua will play a fundamental role in the use of these energy sources. Their physical and chemical properties vary from one feed to another, and this can have some consequences in their necessary upgrading processes. In this paper results on the characterization of 510/sup 0/C-vacuum residua (VR) obtained from Venezuelan Heavy and Medium Oils are presented. These are Morichal (Mo), Merey (Me), Guafita (Gu) and Barinas (Ba). The VR have all an API gravity between 3 and 6, more than 15% asphaltenes, metals above 200 ppm, as well as high contents of nitrogen, more than 6000 ppm, and sulphur, over 1%. It has been found that when these feeds are hydrotreated under similar conditions the processability improves in the order Ba

  1. Heavy-quark production in ultrarelativistic heavy-ion collisions within a partonic transport model

    Uphoff, Jan; Fochler, Oliver; Greiner, Carsten; Xu Zhe

    2010-10-15

    The production and space-time evolution of charm and bottom quarks in nucleus-nucleus collisions at the BNL Relativistic Heavy Ion Collider (RHIC) and the CERN Large Hadron Collider (LHC) are investigated with the partonic transport model BAMPS (Boltzmann approach of multiparton scatterings). Heavy quarks, produced in primary hard parton scatterings during nucleon-nucleon collisions, are sampled using the Monte Carlo event generator pythia or the leading-order minijet model in conjunction with the Glauber model, revealing a strong sensitivity on the parton distribution functions, scales, and heavy-quark mass. In a comprehensive study exploring different charm masses, K factors, and possible initial gluon conditions, secondary production and the evolution of heavy quarks are examined within a fully dynamic BAMPS simulation for central heavy-ion collisions at RHIC and LHC. Although charm production in the quark-gluon plasma can be neglected at RHIC, it is significant at LHC but very sensitive to the initial conditions and the charm mass. Bottom production in the quark-gluon plasma, however, is negligible both at RHIC and LHC.

I review the results of recent lattice calculations relevant for this program including those of B and D decay constants and semileptonic decay form factors, and neutral B mixing. The impact of future improvements of lattice results on the clarification of the origin of several disagreements between theory and experiment which are starting to show up are briefly discussed.

    An integrated upgrading process is disclosed which can be used to lower the specific gravity, viscosity and boiling range of heavy, viscous hydrocarbonaceous oil . The process consists of fractionally distilling the oil, treating its residuum with a hydrogen donor material under hydrocracking conditions, fractionally distilling the effluent from the hydrocracking zone and rehydrogenating that portion boiling from about 180/sup 0/ C to 350/sup 0/ C for recycling to the hydrocracking zone. The liquid portion of the oil not recycled can be recombined into a reconstituted crude suitable for transporting by normal crude pipelines.

    Heavy crude oils are transported by pipeline from deposit location to a remote upgrading location by emulsifying the crude oil using deaerated sodium hydroxide solution, conveying the oilin-water emulsion through the pipeline, and recovery of the oil from the oil-in-water emulsion by inverting the emulsion and dewatering the resulting water-in-oil emulsion. The emulsion inversion may be effected using slaked lime, resulting in recovery of a substantial proportion of the sodium hydroxide used in the initial emulsification. The sodium hydroxide solution may be recycled by a separate pipeline for reuse or treated for discharge.

  5. HEAVY WATER COMPONENTS TEST REACTOR DECOMMISSIONING

    The Heavy Water Components Test Reactor (HWCTR) Decommissioning Project was initiated in 2009 as a Comprehensive Environmental Response, Compensation and Liability Act (CERCLA) Removal Action with funding from the American Recovery and Reinvestment Act (ARRA). This paper summarizes the history prior to 2009, the major D&D activities, and final end state of the facility at completion of decommissioning in June 2011. The HWCTR facility was built in 1961, operated from 1962 to 1964, and is located in the northwest quadrant of the Savannah River Site (SRS) approximately three miles from the site boundary. The HWCTR was a pressurized heavy water test reactor used to develop candidate fuel designs for heavy water power reactors. In December of 1964, operations were terminated and the facility was placed in a standby condition as a result of the decision by the U.S. Atomic Energy Commission to redirect research and development work on heavy water power reactors to reactors cooled with organic materials. For about one year, site personnel maintained the facility in a standby status, and then retired the reactor in place. In the early 1990s, DOE began planning to decommission HWCTR. Yet, in the face of new budget constraints, DOE deferred dismantlement and placed HWCTR in an extended surveillance and maintenance mode. The doors of the reactor facility were welded shut to protect workers and discourage intruders. In 2009 the $1.6 billion allocation from the ARRA to SRS for site footprint reduction at SRS reopened the doors to HWCTR - this time for final decommissioning. Alternative studies concluded that the most environmentally safe, cost effective option for final decommissioning was to remove the reactor vessel, both steam generators, and all equipment above grade including the dome. The transfer coffin, originally above grade, was to be placed in the cavity vacated by the reactor vessel and the remaining below grade spaces would be grouted. Once all above equipment including the dome was removed, a concrete cover was to be placed over the remaining footprint and the groundwater monitored for an indefinite period to ensure compliance with environmental regulations.

    1978-01-01

    An apparatus for accelerating heavy ions to high energies and directing the accelerated ions at a target comprises a source of singly ionized heavy ions of an element or compound of greater than 100 atomic mass units, means for accelerating the heavy ions, a storage ring for accumulating the accelerated heavy ions and switching means for switching the heavy ions from the storage ring to strike a target substantially simultaneously from a plurality of directions. In a particular embodiment the heavy ion that is accelerated is singly ionized hydrogen iodide. After acceleration, if the beam is of molecular ions, the ions are dissociated to leave an accelerated singly ionized atomic ion in a beam. Extraction of the beam may be accomplished by stripping all the electrons from the atomic ion to switch the beam from the storage ring by bending it in magnetic field of the storage ring.

    Van Driesen, R.; Viens, C.H.; Fornoff, L.L.

    1980-01-01

    A study of the upgrading of heavy oil from a representative Venezuelan Jobo crude (9.2/sup 0/API, 4.1% sulfur, and 500 ppm total metals) from the Orinoco area involved 110 computer simulations based on a modified C-E Lummus Refinery Linear Program model on the assumptions of a 125,000 bbl/day refinery built, starting at 1979 prices, for completion by 1986 near the producing field to supply the fuel oil needed to provide oil field steam. All of the upgrading systems were economically attractive; the per cent return-on-investment (ROI) before taxes for the methods studied were: for Lummus LC-Fining, 135.9%; for Exxon's FLEXICOKING, 132.4%; for delayed coking, 119.2%; and for deasphalting, 106.5%. LC-Fining provided the best over-all combination of flexibility, product yield, product quality, and return on investment. The economics favored upgrading to the maximum extent possible; there was a reduction in the ROI for all the upgrading systems when product specifications were lowered from the premium base case (1.2% SO/sub 2/ emitted per million Btu fired). The premium upgraded heavy crude oils should be worth $3.00-$3.50/bbl more than comparable conventional crude oils, could be of up to 27/sup 0/API, and could be substituted, at up to 50%, for conventional crude oils in a typical U.S. refinery.

    1981-07-01

    Conventional theoretical predictions for hadronic production of heavy quarks (Q anti Q) are reviewed and confronted with data. Perturbative hard scattering predictions agree qualitatively well with hidden Q anti Q production (e.g., psi, chi, T) whereas for open Q anti Q-production (e.g., pp ..-->.. ..lambda../sub c//sup +/X) additional mechanisms or inputs are needed to explain the forwardly produced ..lambda../sub c//sup +/ at ISR. It is suggested that the presence of c anti c-pairs on the 1 to 2% level in the hadron Fock state decomposition (intrinsic charm) gives a natural description of the ISR data. The theoretical foundations of the intrinsic charm hypotheses together with its consequences for lepton-induced reactions is discussed in some detail.

    2015-12-11

    We present an attempt to closely mimic the initial stage of heavy ion collisions within holography, assuming a decoupling of longitudinal and transverse dynamics in the very early stage. We subsequently evolve the obtained initial state using state-of-the-art hydrodynamic simulations and compare results with experimental data. We present results for charged hadron pseudorapidity spectra and directed and elliptic flow as functions of pseudorapidity for √sNN = 200GeV Au-Au and 2.76TeV Pb-Pb collisions. As a result, the directed flow interestingly turns out to be quite sensitive to the viscosity. The results can explain qualitative features of the collisions, but the rapiditymore » spectra in our current model is narrower than the experimental data.« less

    A comprehensive and reliable description of nucleus-nucleus interactions represents a crucial need in different interdisciplinary fields. In particular, hadrontherapy monitoring by means of in-beam positron emission tomography (PET) requires, in addition to measuring, the capability of calculating the activity of {beta}{sup +}-decaying nuclei produced in the irradiated tissue. For this purpose, in view of treatment monitoring at the Heidelberg Ion Therapy (HIT) facility, the transport and interaction Monte Carlo code FLUKA is a promising candidate. It is provided with the description of heavy ion reactions at intermediate and low energies by two specific event generators. In-beam PET experiments performed at GSI for a few beam-target combinations have been simulated and first comparisons between the measured and calculated {beta}{sup +}-activity are available.

    1989-01-01

    A review is presented of the heavy oil upgrading industry in Canada. Up to now it has been based on the processing of bitumen extracted from oil sands mining operations at two sites, to produce a residue-free, low sulphur, synthetic crude. Carbon rejection has been the prime process technology with delayed coking being used by Suncor and FLUID COKING at Syncrude. Alternative processes for recovering greater amounts of synthetic crude are examined. These include a variety of hydrogen addition processes and combinations which produce pipelineable materials requiring further processing in downstream refineries with expanded capabilities. The Newgrade Energy Inc. upgrader now under construction in Regina, will use fixed-bed, catalytic, atmospheric-residue, hydrogen processing. Two additional projects, also based on hydrogenation, will use ebullated bed catalyst systems; the expansion of Syncrude, now underway, is using the LC Fining Process whereas the announced Husky Bi-Provincial upgrader is based on H-Oil.

    1995-12-31

    A soft coke-like substance often forms in the liquid product of visbreaking and hydrocracking processes for upgrading vacuum residue of heavy crude oil. This material usually limits the severity or conversion of the process because it accumulates in downstream equipment. Although the amount of such material produced depends on the crude oil, it has not been possible to correlate its production rate to chemical characteristics of the vacuum residue in a quantitative manner In this work we show that the amount of sludge produced per unit weight of vacuum residue feed in laboratory hydrotreating experiments can be correlated with four chemical characteristic of the vacuum residue: the degree of condensed polynuclear aromaticity, the average number of alkyl-groups substituting the polynuclear aromatics, the ratio of heptane insolubles to pentane insoluble-heptane solubles, and the H/C ratio of the latter fraction. The correlation coefficient is 0.95.

  4. Heavy crudes, stocks pose desalting problems

    1982-02-02

    The design of electrostatic desalters for crudes lighter than 30 API is well established and is no longer considered a problem. However, since 1970, the number of desalting applications involving heavy crudes (less than 20 API), syncrudes, and residual fuels has increased markedly. These stocks present unique problems that require additional design considerations. All produced crude oils, including synthetic crude from shale, tar sands, and coal liquefaction, contain impurities that adversely affect production and refining processes, the equipment used in these processes, and the final products. The most common of these impurities are water, salt, solids, metals, and sulfur. The desalting process consists of (1) adding water with a low salt content (preferably fresh) to the feedstock; (2) adequately mixing this added water with the feedstock, which already contains some quantities of salty water, sediment, and/or crystalline salt; and (3) extracting as much water as possible from the feedstock.

    As part of the work building a small heavy-ion induction accelerator ring, or recirculator, at Lawrence Livermore National Laboratory, a diagnostic device measuring the four-dimensional transverse phase space of the beam in just a single pulse has been developed. This device, the Gated Beam Imager (GBI), consists of a thin plate filled with an array of 100-micron diameter holes and uses a Micro Channel Plate (MCP), a phosphor screen, and a CCD camera to image the beam particles that pass through the holes after they have drifted for a short distance. By time gating the MCP, the time evolution of the beam can also be measured, with each time step requiring a new pulse.

    2015-06-01

    Many beyond Standard Model theories predict a new massive gauge boson, a.k.a. 'dark' or 'heavy photon', directly coupling to hidden sector particles with dark charge. The heavy photon is expected to mix with the Standard Model photon through kinetic mixing and therefore couple weakly to normal charge. The Heavy Photon Search (HPS) experiment will search for the heavy photon at the Thomas Jefferson National Accelerator Facility (JLab), in the mass range 20-1000 MeV/c2 and coupling to electric charge ϵ2 = α'/α in the range 10-5 to 10-10. HPS will look for the e+e- decay channel of heavy photons radiated by electron Bremsstrahlung, employing both invariant mass search and detached vertexing techniques. The experiment employs a compact forward spectrometer comprising silicon microstrip detectors for vertexing and tracking and an electromagnetic calorimeter for particle identification and triggering.

    1990-11-01

    The computer program, described in this report, is identified as PWAVED5. It was developed to calculate cross sections for nucleon transfer reactions in low energy heavy ion bombardments. The objective was to calculate cross sections that agree with experimental results for ions of different charge and mass and to develop a predictive capability. It was undertaken because previous heavy ion calculations, for which programs were readily available, appeared to focus primarily on reactions resulting in compound nucleus formation and were not particularly applicable to calculations of binary reaction cross sections at low interaction energies. There are to principal areas in which this computation differs from several other partial wave calculations of heavy-ion reaction cross sections. First, this program is designed specifically to calculate cross sections for nucleon exchange interactions and to exclude interactions that are expected to result in fusion of the two nuclei. A second major difference in this calculation is the use of a statistical distribution to assign the total interaction cross section to individual final mass states.

    On March 6, 1980, the US Department of Energy (DOE) and the Ministry of Energy and Mines of Venezuela (MEMV) entered into a joint agreement which included analysis of heavy crude oils from the Venezuelan Orinoco oil belt.The purpose of this report is to present compositional data and describe new analytical methods obtained from work on the Cerro Negro Orinoco belt crude oil since 1980. Most of the chapters focus on the methods rather than the resulting data on Cerro Negro oil, and results from other oils obtained during the verification of the method are included. In addition, published work on analysis of heavy oils, tar sand bitumens, and like materials is reviewed, and the overall state of the art in analytical methodology for heavy fossil liquids is assessed. The various phases of the work included: distillation and determination of routine'' physical/chemical properties (Chapter 1); preliminary separation of >200{degree}C distillates and the residue into acid, base, neutral, saturated hydrocarbon and neutral-aromatic concentrates (Chapter 2); further separation of acid, base, and neutral concentrates into subtypes (Chapters 3-5); and determination of the distribution of metal-containing compounds in all fractions (Chapter 6).

    Heavy vector-like quarks of charge –1/3, B, have been searched for at the LHC through the decays B → bZ, bh, tW. In models where the B quark also carries charge under a new gauge group, new decay channels may dominate. We focus on the case where the B is charged under a U(1)' and describe simple models where the dominant decay mode is B → bZ' → b(bb¯¯). With the inclusion of dark matter such models can explain the excess of gamma rays from the Galactic center. We develop a search strategy for this decay chain and estimate thatmore » with integrated luminosity of 300 fb–1 the LHC will have the potential to discover both the B and the Z' for B quarks with mass below ~ 1.6 TeV, for a broad range of Z' masses. Furthermore, a high-luminosity run can extend this reach to 2 TeV.« less

In the recent International Symposium on Heavy Ion Inertial Fusion, the attendees met in specialized workshop sessions to consider the needs for research in each area. Each of the workshop groups considered the key questions of this report: (1) Is this an appropriate time for international collaboration in HIF? (2) Which problems are most appropriate for such collaboration? (3) Can the sharing of target design information be set aside until other driver and systems issues are better resolved, by which time it might be supposed that there could be a relaxation of classification of target issues? (4) What form(s) of collaboration are most appropriate, e.g., bilateral or multilateral? (5) Can international collaboration be sensibly attempted without significant increases in funding for HIF? The authors of this report share the conviction that collaboration on a broad scale is mandatory for HIF to have the resources, both financial and personnel, to progress to a demonstration experiment. Ultimately it may be possible for a single driver with the energy, power, focusibility, and pulse shape to satisfy the needs of the international community for target physics research. Such a facility could service multiple experimental chambers with a variety of beam geometries and target concepts.

    1997-12-31

    The spontaneous-fission properties of Fm isotopes undergo dramatic changes between {sup 256}Fm and {sup 258} Fm. The fission fragments of the former isotope are mass asymmetric with kinetic energies of about 200 MeV, whereas the fission fragments of the latter isotope are symmetric with kinetic energies of about 235 MeV. This rapid change occurs because the division into nearly doubly magic fragments near {sup 132}Sn becomes possible and opens up new valleys in the fission potential-energy surface. In the cold-fusion reactions leading to the heaviest elements, the nearly doubly magic targets and/or projectiles may give rise to important features associated with this magicity. Cold fusion is thought to favor heavy-element formation because it leads to low excitation energies of the compound nuclei. We investigate how near-magic targets and projectiles may lead to persistent survivability of the shells in the fusion valley as the ions merge, in addition to their effect on the compound-nucleus excitation energy.

    Since 2000, six new super-heavy elements with atomic numbers 113 through 118 have been synthesized in hot fusion reactions of 48Ca beams on actinide targets. These target materials, including 242Pu, 244Pu, 243Am, 245Cm, 248Cm, 249Cf, and 249Bk, are available in very limited quantities and require specialized production and processing facilities resident in only a few research centers worldwide. This report describes the production and chemical processing of heavy actinide materials for super-heavy element research, current availabilities of these materials, and related target fabrication techniques. The impact of actinide materials in super-heavy element discovery is reviewed, and strategies for enhancing themore » production of rare actinides including 249Bk, 251Cf, and 254Es are described.« less

    1995-10-01

    U.S. light crude oil production has steadily declined over the last two decades. However, huge known heavy oil deposits in the North American continent remain largely untapped. In the past 10 years, the API gravity of crude oils has been decreasing by about 0.17% per year, and the sulfur content has been increasing by about 0.027% per year. As the API gravity of crude oil decreases, there will be an urgent need for economically viable new technologies to upgrade the heavy oil to a high API gravity feed stock for the refineries. The Idaho National Engineering Laboratory is investigating an innovative plasma process to upgrade heavy oil and refinery residuum. This paper will present some of the results and the implications of this technology for heavy oil upgrade and conversion.

    This work provides an in-depth assessment of international technology for the recovery and upgrading of heavy crude oil and tar sands. The technologies included are currently in use, under development, or planned; emphasis is placed on post-1978 activities. The heavy oil technologies and processes considered include methods relating to the exploitation of heavy oil reservoirs, such as production from underground workings, all types of improved or enhanced recovery, subsurface extraction, and well rate stimulation. The tar sands section includes sizing the resource base and reviewing and evaluating past, present, and planned research and field developments on processes for mining, producing, extracting, and upgrading very heavy oils recovered from tar sands, e.g., bitumen recovery from tar sands where primary production was impossible because of the oil's high viscosity. 616 references.

    We investigate the dissociation of a heavy meson in the medium composed of light quarks and gluons. In the quark-gluon plasma, the dissociation length of the heavy meson becomes short as the temperature or quark chemical potential increases. On the contrary, in the hadronic phase the dissociation length becomes large as the chemical potential increases, due to the different dissociation mechanism with one used in the quark-gluon plasma.

  5. Solubilities of heavy fossil fuels in compressed gases

    SciTech Connect (OSTI)

    Monge, A. Jr.

    1982-01-01

    Design of processes for upgrading heavy fossil fuels such as coal-derived liquids, heavy petroleum fractions, tar sands, and shale oil, requires quantitative information for equilibrium properties of the fossil fuel in the presence of compressed light gases at elevated temperatures. Presented here are methods to predict and measure solubilities of heavy fossil fuels in compressed gases in the region ambient to 100 bar and 600 K. A molecular-thermodynamic model is used to predict heavy fossil-fuel solubilities. The heavy fuel is fractionated ina spinning-band column at low pressure and high reflux; each fraction is considered to be a pseudo-component. Each fraction is characterized by one vapor-pressure datum (obtained during fractionation), elemental analysis, and proton-NMR spectra (to determine aromaticity). Liquid-phase properties are obtained from the SWAP equation for vapor pressure and from a density correlation. Vapor-phase properties are obtained using the virial equation of state with virial coefficients from Kaul's correlation. The molecular-thermodynamic model has been used to establish a design-oriented computer program for calculating heavy, fossil-fuel solubility for general application in process design and, in particular, for isobaric condensation as a function of temperature as required for design of a continuous-flow heat exchanger. A total-vaporization technique is used to measure the solubilities of narrow-boiling, heavy fossil-fuel fractions in compressed gases. The solubility of a heavy fraction is determined from the volume of gas required to vaporize completely a small, measured mass of fossil-fuel sample. To test the molecular-thermodynamic model, the total-vaporization technique has been used to measure the solubilities of two Lurgi coal-tar fractions in compressed methane. Predicted and experimental solubilities agree well.

    Environmental and occupational exposure to heavy metals such as cadmium, mercury and lead results in severe health hazards including prenatal and developmental defects. The deleterious effects of heavy metal ions have hitherto been attributed to their interactions with specific, particularly susceptible native proteins. Here, we report an as yet undescribed mode of heavy metal toxicity. Cd{sup 2+}, Hg{sup 2+} and Pb{sup 2+} proved to inhibit very efficiently the spontaneous refolding of chemically denatured proteins by forming high-affinity multidentate complexes with thiol and other functional groups (IC{sub 50} in the nanomolar range). With similar efficacy, the heavy metal ions inhibited the chaperone-assisted refolding of chemically denatured and heat-denatured proteins. Thus, the toxic effects of heavy metal ions may result as well from their interaction with the more readily accessible functional groups of proteins in nascent and other non-native form. The toxic scope of heavy metals seems to be substantially larger than assumed so far.

    Ion beams have been used for surface modification, semiconductor device fabrication and for material analysis, which makes ion-material interactions of significant importance. Ion implantation will produce new compositions near the surface by ion mixing or directly by implanting desired ions. Ions exchange their energy to the host material as they travel into the material by several different processes. High energy ions ionize the host atoms before atomic collisions transfer the remaining momentum and stop the incident ion. As they penetrate the surface, the low energy ions ionize the host atoms, but also have a significantly large momentum transfer mechanism near the surface of the material. This leads to atoms, groups of atoms and electrons being ejected from the surface, which is the momentum transfer process of sputtering. This talk addresses the acoustic waves generated during ion implantation using modulated heavy ion beams. The mechanisms for elastic wave generation during ion implantation, in the regimes where sputtering is significant and where implantation is dominant and sputtering is negligible, has been studied. The role of momentum transfer and thermal energy production during ion implantation was compared to laser generated elastic waves in an opaque solid as a reference, since laser generated ultrasound has been extensively studied and is fairly well understood. The thermoelastic response dominated in both high and low ion energy regimes since, apparently, more energy is lost to thermal heat producing mechanisms than momentum transfer processes. The signal magnitude was found to vary almost linearly with incident energy as in the laser thermoelastic regime. The time delays for longitudinal and shear waves-were characteristic of those expected for a purely thermal heating source. The ion beams are intrinsically less sensitive to the albedo of the surface.

  18. Heavy oil and tar sands recovery and upgrading: international technology

    SciTech Connect (OSTI)

    Schumacher, M.M.

    1982-01-01

    This book provides an in-depth assessment of international technology for the recovery and upgrading of heavy crude oil and tar sands. The technologies included are currently in use, under development, or planned; emphasis is placed on post-1978 activities. The heavy oil technologies and processes considered in Part I include methods relating to the exploitation of heavy oil reservoirs, such as production from undergorun workings, all types of improved or enhanced recovery, subsurface extraction, and well rate stimulation. Furthermore, even though heavy crudes are understood to include only those liquid or semiliquid hydrocarbons with a gravity of 20/sup 0/API or less, technology applied to lighter crude oils with in situ viscosities of the same order of magnitude as some US heavy oils is also included. The scope of the tar sands section (Part II) includes sizing the resource base and reviewing and evaluatin past, present, and planned research and field developments on processes for mining, producing, extracting, and upgrading very heavy oils recovered from tar sands, e.g., bitumen recovery from tar sands where primary production was impossible because of the oil's high viscosity. On the production side, very heavy oil is defined as having a gravity less than 10/sup 0/ to 12/sup 0/API and greater than 100,000-centipoise viscosity at 50/sup 0/F. On the upgrading side, hydrocarbons whose characteristics dictated additional processing prior to conventional refining into salable products (1050+/sup 0/ material) were included, regardless of origin, in order to encompass all pertinent upgrading technologies.

  19. Heavy oil reservoirs recoverable by thermal technology. Annual report

    Kujawa, P.

    1981-02-01

    The purpose of this study was to compile data on reservoirs that contain heavy oil in the 8 to 25/sup 0/ API gravity range, contain at least ten million barrels of oil currently in place, and are non-carbonate in lithology. The reservoirs within these constraints were then analyzed in light of applicable recovery technology, either steam-drive or in situ combustion, and then ranked hierarchically as candidate reservoirs. The study is presented in three volumes. Volume I presents the project background and approach, the screening analysis, ranking criteria, and listing of candidate reservoirs. The economic and environmental aspects of heavy oil recovery are included in appendices to this volume. This study provides an extensive basis for heavy oil development, but should be extended to include carbonate reservoirs and tar sands. It is imperative to look at heavy oil reservoirs and projects on an individual basis; it was discovered that operators, and industrial and government analysts will lump heavy oil reservoirs as poor producers, however, it was found that upon detailed analysis, a large number, so categorized, were producing very well. A study also should be conducted on abandoned reservoirs. To utilize heavy oil, refiners will have to add various unit operations to their processes, such as hydrotreaters and hydrodesulfurizers and will require, in most cases, a lighter blending stock. A big problem in producing heavy oil is that of regulation; specifically, it was found that the regulatory constraints are so fluid and changing that one cannot settle on a favorable recovery and production plan with enough confidence in the regulatory requirements to commit capital to the project.

    2006-12-26

    A process for removing heavy metals from water is provided. The process includes the steps of introducing magnetite to a quantity of water containing heavy metal. The magnetite is mixed with the water such that at least a portion of, and preferably the majority of, the heavy metal in the water is bound to the magnetite. Once this occurs the magnetite and absorbed metal is removed from the water by application of a magnetic field. In most applications the process is achieved by flowing the water through a solid magnetized matrix, such as steel wool, such that the magnetite magnetically binds to the solid matrix. The magnetized matrix preferably has remnant magnetism, but may also be subject to an externally applied magnetic field. Once the magnetite and associated heavy metal is bound to the matrix, it can be removed and disposed of, such as by reverse water or air and water flow through the matrix. The magnetite may be formed in-situ by the addition of the necessary quantities of Fe(II) and Fe(III) ions, or pre-formed magnetite may be added, or a combination of seed and in-situ formation may be used. The invention also relates to an apparatus for performing the removal of heavy metals from water using the process outlined above.

  2. A novel process for upgrading heavy oil emulsions

    Canada has extensive reserves of high sulfur heavy oils. These heavy oils are recovered primarily by steam injection techniques. As a result, the heavy oils are obtained as emulsions at well-heads. The heavy oils, being high in sulfur and metals, and low in hydrogen to carbon atomic ratio, require upgrading such as desulfurization and hydrocracking before it can be used in conventional refineries. Conventional emulsion treatment and desulfurization technology require multistage processing. Thus, alternative technologies for processing heavy oil emulsions would be attractive. The authors have recently developed a novel single stage process for upgrading emulsions via activation of water to provide hydrogen in situ for catalytic desulfurization and hydrocracking. Current work is focused on the desulfurization aspect of upgrading, using benzothiophene as the model sulfur compound and molybdic acid as the catalyst. At 340 C and a CO loading pressure of 600 psi, up to 86% sulfur removal was obtained. As well, in situ generated H{sub 2} was found to be more active than externally supplied molecular H{sub 2}. A likely pathway for desulfurization of benzothiophene was via the initial hydrogenation of benzothiophene to dihydrobenzothiophene followed by hydrogenolysis to give ethylbenzene and H{sub 2}S.

    The Annual Energy Outlook 2010 Reference case is best described as a current laws and regulations case, because it generally assumes that existing laws and fully promulgated regulations will remain unchanged throughout the projection period, unless the legislation establishing them specifically calls for them to end or change. The Reference case often serves as a starting point for the analysis of proposed legislative or regulatory changes, a task that would be difficult if the Reference case included projected legislative or regulatory changes.

    Intense heavy-ion beams have long been considered a promising driver option for inertial-fusion energy production. This paper briefly compares inertial confinement fusion (ICF) to the more-familiar magnetic-confinement approach and presents some advantages of using beams of heavy ions to drive ICF instead of lasers. Key design choices in heavy-ion fusion (HIF) facilities are discussed, particularly the type of accelerator. We then review experiments carried out at Lawrence Berkeley National Laboratory (LBNL) over the past thirty years to understand various aspects of HIF driver physics. A brief review follows of present HIF research in the US and abroad, focusing on a new facility, NDCX-II, being built at LBNL to study the physics of warm dense matter heated by ions, as well as aspects of HIF target physics. Future research directions are briefly summarized.

  6. A predictive standard model for heavy electron systems

    2010-01-01

    We propose a predictive standard model for heavy electron systems based on a detailed phenomenological two-fluid description of existing experimental data. It leads to a new phase diagram that replaces the Doniach picture, describes the emergent anomalous scaling behavior of the heavy electron (Kondo) liquid measured below the lattice coherence temperature, T*, seen by many different experimental probes, that marks the onset of collective hybridization, and enables one to obtain important information on quantum criticality and the superconducting/antiferromagnetic states at low temperatures. Because T* is {approx} J{sup 2} {rho}/2, the nearest neighbor RKKY interaction, a knowledge of the single-ion Kondo coupling, J, to the background conduction electron density of states, {rho}, makes it possible to predict Kondo liquid behavior, and to estimate its maximum superconducting transition temperature in both existing and newly discovered heavy electron families.

    Canadian oilsands and heavy oil operators are using operational upgrades and substantial research outlays as key weapons against an economic squeeze brought about largely by volatile oil prices. The Canadian Oilsands Network for Research and Development (Conrad) was formed late last year to coordinate nonproprietary research on oilsands technology among industry, government, and academic centers. The Alberta Oilsands Technology and Research Authority (Aostra), now part of Alberta's energy department, also is active with a number of industry partners in oilsands and heavy oil research. Aostra has made significant gains in demonstration projects. The paper discusses upgrader problems, key ingredients to improving operations and development of new technology, syncrude operations, cost, environmental upgrading, Imperials' heavy oil operation at Cold Lake, Shell's operation at Peace River and Amoco operations in Canada.

    As conventional crude oil reserves decrease and prices go up, heavy crude oil (HCO) is getting more attention from oil companies and governments. It was felt that some clarification was needed regarding these products and a review of known fields was conducted to sort out ranges of physical and composition characteristics for definition and classification purposes. A summary of this review with a proposal for classification was presented at the Second International Conference on Heavy Crude and Tar Sands held in Caracas in Feb. 1982. This Caracas conference, organized jointly by the United Nations Institute for Training and Research (UNITAR) and Petroleos de Venezuela debated the definition, characteristics, reserves/resources, production/enhanced oil recovery, and upgrading of heavy crude oils. This work is based, in part, on some of the Caracas conference's discussions.

    The effects of hybridization on heavy-duty vehicles are not well understood. Heavy vehicles represent a broader range of applications than light-duty vehicles, resulting in a wide variety of chassis and engine combinations, as well as diverse driving conditions. Thus, the strategies, incremental costs, and energy/emission benefits associated with hybridizing heavy vehicles could differ significantly from those for passenger cars. Using a modal energy and emissions model, they quantify the potential energy savings of hybridizing commercial Class 3-7 heavy vehicles, analyze hybrid configuration scenarios, and estimate the associated investment cost and payback time. From the analysis, they conclude that (1) hybridization can significantly reduce energy consumption of Class 3-7 heavy vehicles under urban driving conditions; (2) the grid-independent, conventional vehicle (CV)-like hybrid is more cost-effective than the grid-dependent, electric vehicle (EV)-like hybrid, and the parallel configuration is more cost-effective than the series configuration; (3) for CV-like hybridization, the on-board engine can be significantly downsized, with a gasoline or diesel engine used for SUVs perhaps being a good candidate for an on-board engine; (4) over the long term, the incremental cost of a CV-like, parallel-configured Class 3-4 hybrid heavy vehicle is about %5,800 in the year 2005 and $3,000 in 2020, while for a Class 6-7 truck, it is about $7,100 in 2005 and $3,300 in 2020; and (5) investment payback time, which depends on the specific type and application of the vehicle, averages about 6 years under urban driving conditions in 2005 and 2--3 years in 2020.

    We calculate the axial couplings of mesons and baryons containing a heavy quark in the static limit using lattice QCD. These couplings determine the leading interactions in heavy hadron chiral perturbation theory and are central quantities in heavy quark physics, as they control strong decay widths and the light-quark mass dependence of heavy hadron observables. Our analysis makes use of lattice data at six different pion masses, 227 MeV < m{sub {pi}} < 352 MeV, two lattice spacings, a = 0.085, 0.112 fm, and a volume of (2.7 fm){sup 3}. Our results for the axial couplings are g{sub 1} = 0.449(51), g{sub 2} = 0.84(20), and g{sub 3} = 0.71(13), where g{sub 1} governs the interaction between heavy-light mesons and pions and g{sub 2,3} are similar couplings between heavy-light baryons and pions. Using our lattice result for g{sub 3}, and constraining 1/m{sub Q} corrections in the strong decay widths with experimental data for {Sigma}{sub c}{sup (*)} decays, we obtain {Gamma}[{Sigma}{sub b}{sup (*)} {yields} {Lambda}{sub b} {pi}{sup {+-}}] = 4.2(1.0), 4.8(1.1), 7.3(1.6), 7.8(1.8) MeV for the {Sigma}{sub b}{sup +}, {Sigma}{sub b}{sup -}, {Sigma}{sub b}{sup *+}, {Sigma}{sub b}{sup *-} initial states, respectively. We also derive upper bounds on the widths of the {Xi}{sub b}{sup prime(*)} baryons.

    Little Higgs models provide a natural explanation for the lightness of the Higgs mass. Through the mechanism of collective symmetry breaking, one loop quadratic divergent contributions to the Higgs mass are avoided. In these models a heavy partner of the Top quark appears as required to cancel out the Top's loop contribution. This heavy Top could be produced at the LHC mainly in the single mode. Because of flavor mixing a large FCNC gtT coupling can be generated at one loop that could boost the single T production mode through gg fusion.

These ingredients enable us to construct the continuum-limit operator needed to determine the oscillation frequency of neutral B mesons. The matching is then carried out at the one-loop level. We also present an updated preliminary result for the SU(3)-breaking ratio {zeta}, based on calculations using the MILC Collaboration's ensembles of lattice gauge fields.

    The sulphur emissive capability, on combustion, of coke which is formed during upgrading of sulphur-containing heavy crude oils, including oil sands bitumen, or residua is decreased by the addition of slaked lime or calcium oxide to the heavy crude oil prior to coking. The presence of the slaked lime or calcium oxide leads to an increased yield of liquid distillates at coking temperatures of about 450/sup 0/ to about 500/sup 0/ C. Ash remaining after combustion of the coke may be leached to recover nickel and vanadium values therefrom.

    Relativistic light-front bound-state equations for mesons and baryons can be constructed in the chiral limit from the supercharges of a superconformal algebra which connect baryon and meson spectra. Quark masses break the conformal invariance, but the basic underlying supersymmetric mechanism, which transforms meson and baryon wave functions into each other, still holds and gives remarkable connections across the entire spectrum of light and heavy-light hadrons. As a result, we also briefly examine the consequences of extending the supersymmetric relations to double-heavy mesons and baryons.

    Kim, Eun-Hwa; Johnson, Jay R.; Kim, Hyomin; Lee, Dong-Hun

    2014-05-01

    We present a method to infer heavy ion concentration ratios from EMIC wave observations that result from ionion hybrid (IIH) resonance. A key feature of the ion-ion hybrid resonance is the concentration of wave energy in a field-aligned resonant mode that exhibits linear polarization. This mode converted wave is localized at the location where the frequency of a compressional wave driver matches the IIH resonance condition, which depends sensitively on the heavy ion concentration. This dependence makes it possible to estimate the heavy ion concentration ratio. In this letter, we evaluate the absorption coefficients at the IIH resonance at Earth's geosynchronous orbit for variable concentrations of He+ and field-aligned wave numbers using a dipole magnetic field. Although wave absorption occurs for a wide range of heavy ion concentrations, it only occurs for a limited range of field-aligned wave numbers such that the IIH resonance frequency is close to, but not exactly the same as the crossover frequency. Using the wave absorption and observed EMIC waves from GOES-12 satellite, we demonstrate how this technique can be used to estimate that the He+ concentration is around 4% near L = 6.6.

    In August 2006, the CERN Theory Unit announced to restructure its visitor program and to create a 'CERN Theory Institute', where 1-3 month long specific programs can take place. The first such Institute was held from 14 May to 10 June 2007, focusing on 'Heavy Ion Collisions at the LHC - Last Call for Predictions'. It brought together close to 100 scientists working on the theory of ultra-relativistic heavy ion collisions. The aim of this workshop was to review and document the status of expectations and predictions for the heavy ion program at the Large Hadron Collider LHC before its start. LHC will explore heavy ion collisions at {approx} 30 times higher center of mass energy than explored previously at the Relativistic Heavy Ion Collider RHIC. So, on the one hand, the charge of this workshop provided a natural forum for the exchange of the most recent ideas, and allowed to monitor how the understanding of heavy ion collisions has evolved in recent years with the data from RHIC, and with the preparation of the LHC experimental program. On the other hand, the workshop aimed at a documentation which helps to distinguish pre- from post-dictions. An analogous documentation of the 'Last Call for Predictions' [1] was prepared prior to the start of the heavy-ion program at the Relativistic Heavy Ion Collider RHIC, and it proved useful in the subsequent discussion and interpretation of RHIC data. The present write-up is the documentation of predictions for the LHC heavy ion program, received or presented during the CERN TH Institute. The set-up of the CERN TH Institute allowed us to aim for the wide-most coverage of predictions. There were more than 100 presentations and discussions during the workshop. Moreover, those unable to attend could still participate by submitting predictions in written form during the workshop. This followed the spirit that everybody interested in making a prediction had the right to be heard. To arrive at a concise document, we required that each prediction should be summarized on at most two pages, and that predictions should be presented, whenever possible, in figures which display measurable quantities. Full model descriptions were not accepted--the authors were encouraged to indicate the relevant references for the interested reader. Participants had the possibility to submit multiple contributions on different topics, but it was part of the subsequent editing process to ensure that predictions on neighboring topics were merged wherever possible. The contributions summarized here are organized in several sections,--though some of them contain material related with more than one section--roughly by going from low transverse momentum to high transverse momentum and from abundant to rare measurements. In the low transverse momentum regime, we start with predictions on multiplicity distributions, azimuthal asymmetries in particle production and hadronic flavor observables, followed by correlation and fluctuation measurements. The contributions on hard probes at the LHC start with predictions for single inclusive high transverse momentum spectra, and jets, followed by heavy quark and quarkonium measurements, leptonic probes and photons. A final section 'Others' encompasses those predictions which do not fall naturally within one of the above-mentioned categories, or discuss the more speculative phenomena that may be explored at the LHC.

    This report contains estimates of the product yields and product properties from four separate, commercial-scale Aurabon heavy oil upgrading complexes capable of producing low-sulfur, hydrogen-rich products from various fractions of either a Venezuelan Boscan or a Canadian Lloydminster heavy oil feedstock. These estimates formed the basis for the development of the necessary process engineering work, including the general equipment specifications for the major equipment items included in each processing unit, required to determine cost and utilities estimates, construction labor requirements, and an estimated construction cost schedule for each of the four upgrading complexes. In addition to the above information, estimates of the yields and properties of the products produced during the upgrading of the heavy portion of the Aurabon product by both the hydrocracking and fluidized catalytic cracking processes are also included in this report. Consistent with the provisions of the executed contract for this work, those portions of the engineering work which were considered proprietary to UOP, including the heat and material balances, process flow diagrams, piping and instrument diagrams, and general equipment specifications developed for each process unit contained in the heavy oil upgrading facilities have not been included in this report. This report does, however, contain sufficient non-proprietary information to provide the reader with a general understanding of the Aurabon process and detailed information regarding the performance of the process when upgrading the two heavy oil feedstocks studied. UOP has allowed the consulting firms of Walk, Haydel and Associates of New Orleans, Louisiana and Texas Consultants, Inc. of Houston, Texas to review various portions of the engineering work developed by UOP under this contract. 1 reference, 13 figures, 22 tables.

    The steady decline in proven conventional oil deposits world wide has increased the emphasis on the use of heavy oil and bitumen. Most of the heavy oil and oil sand deposits share the common problem of providing very little or no primary production. They require a reduction in viscosity of the oil to make it flow. The oil in place and the reservoir characteristics are generally studied carefully to determine the design of the recovery process most applicable to the deposit and to evaluate its potential. Many of these same characteristics are also used to evaluate the oil with respect to upgrading, refining and final usage in the form of products. A variety of processes have been developed most of which utilize heat either in the form of steam or combustion to mobolize the oil in the reservoir. These processes vary considerably from rather mild conditions for steam stimulation to quite severe for combustion recovery. Figure 1 shows a typical schematic of an insitu combustion process. Many variations of forward combustion are used in the field to produce oil. Depending upon the severity of the recovery process in the recovered oil may be similar to the oil in the deposit or may be highly modified (oxidized, polymerized or upgraded). A memorandum of Understanding was signed by the Governments of the United States of America, Canada and the Provinces of Saskatchewan and Alberta to study different aspects of the problems related to the recovery of oil from heavy oil and sand deposits. One phase of the study is to determine the effects of different methods of in-situ recovery on the composition of recovered bitumen and heavy oils. This paper describes the findings from a study of fireflood process in a heavy oil deposit located in the Cummings formation of the Eyehill Field in Saskatchewan, Canada.

    The triply heavy baryons in the standard model formed in direct c and b quark fragmentation are the {omega}{sub ccc}, {omega}{sub ccb}, {omega}{sub cbb} and {omega}{sub bbb} baryons. We calculate their fragmentation functions in leading order of perturbative QCD. The universal fragmentation probabilities fall within the range of 10{sup -5}-10{sup -7}.We also evaluate their cross section at the LHC ({radical}(s)=14 TeV) using next-to-leading order matrix elements for heavy quark-antiquark pair production. We present the differential cross sections as functions of the transverse momentum as well as the total cross sections. They range from a few nb to a few pb.

  7. Situ formation of apatite for sequestering radionuclides and heavy metals

    2003-07-15

    Methods for in situ formation in soil of a permeable reactive barrier or zone comprising a phosphate precipitate, such as apatite or hydroxyapatite, which is capable of selectively trapping and removing radionuclides and heavy metal contaminants from the soil, while allowing water or other compounds to pass through. A preparation of a phosphate reagent and a chelated calcium reagent is mixed aboveground and injected into the soil. Subsequently, the chelated calcium reagent biodegrades and slowly releases free calcium. The free calcium reacts with the phosphate reagent to form a phosphate precipitate. Under the proper chemical conditions, apatite or hydroxyapatite can form. Radionuclide and heavy metal contaminants, including lead, strontium, lanthanides, and uranium are then selectively sequestered by sorbing them onto the phosphate precipitate. A reducing agent can be added for reduction and selective sequestration of technetium or selenium contaminants.

    The unexplored area of heavy neutron-rich nuclides is extremely important for the understanding of the r process of astrophysical nucleogenesis. For elements with Z>100 only neutron deficient isotopes (located to the left of the stability line) have been synthesized so far. The 'north-east' area of the nuclear map can be reached neither in fusion reactions nor in fragmentation processes. Low energy multi-nucleon transfer reactions are quite promising for the production and study of neutron-rich heavy nuclei including those located at the superheavy (SH) island of stability [1]. The neutron capture process is considered here as an alternative method for the production of SH nuclei. Requirements for the pulsed reactors of the next generation that could be used for the synthesis of long-living neutron rich SH nuclei are formulated. Formation of SH nuclei in supernova explosions is also discussed and the abundance of SH elements in nature is estimated.

    2002-02-01

    The sensitivity of the ATLAS detector to the discovery of a heavy charged Higgs boson is presented. Assuming a heavy SUSY spectrum, the most promising channels above the top quark mass are H{sup {+-}} {yields} tb and h{sup {+-}} {yields} {tau}{sup {+-}}{nu}{sub {tau}} which provide coverage in the low and high tan {beta} regions up to {approx} 600 GeV. The achievable precisions on the charged Higgs mass and tan {beta} determination are also discussed. The H{sup {+-}} {yields} W{sup {+-}}h{sup 0} channel, though restricted to a small MSSM parameter space, shows a viable signal in NMSSM where the parameter space is less constrained. The observation of the channel H{sup -} {yields} {tau}{sub L}{sup -} {nu}{sub {tau}} + c.c. may constitute a distinctive evidence for models with singlet neutrinos in large extra dimensions.

    2010-08-01

    We apply the resummed version of the Luescher formula to analyze finite volume corrections to the mass of the nucleon and of heavy mesons. We show that by applying the subthreshold expansion of the scattering amplitudes one can express the finite volume corrections in terms of only a few physical observables and the size of the box. In the case of the nucleon, the available information about the quark mass dependence of these physical quantities is discussed and used to assess the finite volume corrections to the nucleon mass as a function of the quark mass including a detailed analysis of the remaining uncertainties. For heavy mesons, the Luescher formula is derived both fully relativistically and in a nonrelativistic approximation and a first attempt at a numerical analysis is made.

    Recognizing the lack of operational data on alternative fuel heavy-truck trucks, NREL contracted with the Trucking Research Institute (TRI) in 1994 to obtain a cooperative agreement with Liquid Carbonic. The purpose of this agreement was to (1) purchase and operate liquid natural gas- (LNG-) powered heavy-duty tractor-trailers with prototype Detroit Diesel Corporation (DDC) Series 60 natural gas (S60G) engines in over-the-road commercial service applications; and (2) collect and provide operational data to DDC to facilitate the on-road prototype development of the engine and to NREL for the Alternative Fuels Data Center. The vehicles operated from August 1994 through April of 1997 and led to a commercially available, emissions-certified S60G in 1998. This report briefly documents the engine development, the operational characteristics of LNG, and the lessons learned during the project.

    1997-01-01

    The implications of the massive top quark on heavy flavor transitions are explored. We review the generation of quark masses and mixings and the determination techniques, and present the status of the elements of the weak mixing matrix. Purely leptonic decays of heavy mesons are briefly summarized. We present a general introduction to flavor changing neutral currents and an extensive summary of radiative and other rare decay modes. The physics of neutral meson mixing is reviewed and applied to each meson system. We describe the phenomenology of CP violation and how it may be measured in meson decays. Standard Model predictions are given in each case and the effects of physics beyond the Standard Model are also discussed. Throughout, we contrast these transitions in the K and B meson systems to those in the D meson and top-quark sectors.

    The authors are concerned with Exxon's Fluid and Flexicoking processes which allow the refiner to convert the bottom of the crude barrel to clean products. This article primarily discusses enhancement of liquid yields from both processes and reduction of low-Btu gas from Flexicoking. Also discussed are recent advances in coking technology, which could make these processes more attractive. Flexicoking is an integrated coking/gasification process for upgrading heavy feedstocks. The process converts these feeds to a 99% yield of fuel gas, naphtha, middle distillates, heavy gas oil, and a low-sulfur coke gas. The remaining 1% is petroleum coke containing metals and other ash components present in the feed. 6 refs.

Excellent consistency is observed across all the experiments at the LHC (at center of mass energysNN=2.76 TeV) for the measurements such as charged particle multiplicity density, azimuthal anisotropy coefficients, and nuclear modification factor of charged hadrons. Comparison to similar measurements from the Relativistic Heavy Ion Collider (RHIC) at lower energy (sNN=200 GeV) suggests that the system formed at LHC has a higher energy density and larger system size and lives for a longer time. These measurements are compared to model calculations to obtain physical insights on the properties of matter created at the RHIC and LHC.« less

    In heavy ion operation the LHC interaction region at IP2 will have a low-{beta} optics for collisions. The dynamic aperture is therefore sensitive to magnetic field errors in the interaction region quadrupoles and dipoles. The authors investigate the effect of the magnetic field errors on the dynamic aperture and evaluate the effectiveness of local interaction region correctors. The dynamic aperture and the tune space are computed for different crossing angles.

This paper describes a history match of previous field behavior and systematically analyzes through the use of numerical simulation the potential benefits to production of further waterflooding (with and without infill drilling), steamflooding, and horizontal drilling. It is found that the remaining oil recovery potential of a steamflood with horizontal well is significantly higher than that of any of the waterflood options.

    1984-06-01

    The market potential for two not-yet-commercialized, proprietary processes for upgrading heavy oil was evaluated. Dynacracking (TM) of Hydrocarbon Research Inc. (HRI) and Aurabon of UOP Process Division (UOP), including an integrated commercial hydrotreating unit were the processes studied. The report concludes that while a large market for Heavy Oil Processing (HOP) units was originally forecast as the result of the shift to heavier crudes by US refiners under a given demand slate and refinery configuration, this market has either eroded due to massive demand shifts (both in volumetric and relative product mix terms) or largely been satisfied on an accelerated basis (due to downstream restructuring pressures) by units already constructed or under firm commitment utilizing other HOP technology. Dynacracking or Aurabon does not appear to offer the substantial economic advantage needed to replace other HOP units already committed. However, additional demands for HOP units couold arise, particularly on a regional basis, if significant additional foreign or domestic sources of heavy crude are introduced into the supply picture or the demand structure moves dramatically away from that currently foreseen by the EIA. Expected profit margins were calculated for both processes, allowing $2/barrel extra credit to the Aurabon products because of their higher quality. Both processes appear to produce about the same fraction of vacuum bottoms when processing the same crude. Dynacracking produces a higher proportion of naphtha and Aurabon produces substantially more heavy distillate. This report is not intended to serve as a basis of selecting either process for a particular installation. 10 references, 7 figures, 29 tables.

  11. RESEARCH OIL RECOVERY MECHANISMS IN HEAVY OIL RESERVOIRS

    1999-06-01

    The United States continues to rely heavily on petroleum fossil fuels as a primary energy source, while domestic reserves dwindle. However, so-called heavy oil (10 to 20{sup o}API) remains an underutilized resource of tremendous potential. Heavy oils are much more viscous than conventional oils. As a result, they are difficult to produce with conventional recovery methods such as pressure depletion and water injection. Thermal recovery is especially important for this class of reservoirs because adding heat, usually via steam injection, generally reduces oil viscosity dramatically. This improves displacement efficiency. The research described here was directed toward improved understanding of thermal and heavy-oil production mechanisms and is categorized into: (1) flow and rock properties; (2) in-situ combustion; (3) additives to improve mobility control; (4) reservoir definition; and (5) support services. The scope of activities extended over a three-year period. Significant work was accomplished in the area of flow properties of steam, water, and oil in consolidated and unconsolidated porous media, transport in fractured porous media, foam generation and flow in homogeneous and heterogeneous porous media, the effects of displacement pattern geometry and mobility ratio on oil recovery, and analytical representation of water influx. Significant results are described.

    The goal of the Heavy Ion Fusion (HIF) Program is to apply high-current accelerator technology to IFE power production. Ion beams of mass {approx}100 amu and kinetic energy {>=} 1 GeV provide efficient energy coupling into matter, and HIF enjoys R&D-supported favorable attributes of: (1) the driver, projected to be robust and efficient; see 'Heavy Ion Accelerator Drivers.'; (2) the targets, which span a continuum from full direct to full indirect drive (and perhaps fast ignition), and have metal exteriors that enable injection at {approx}10 Hz; see 'IFE Target Designs'; (3) the near-classical ion energy deposition in the targets; see 'Beam-Plasma Interactions'; (4) the magnetic final lens, robust against damage; see 'Final Optics-Heavy Ion Beams'; and (5) the fusion chamber, which may use neutronically-thick liquids; see 'Liquid-Wall Chambers.' Most studies of HIF power plants have assumed indirect drive and thick liquid wall protection, but other options are possible.

  13. Heavy Water Components Test Reactor Decommissioning - Major Component Removal

    Austin, W.; Brinkley, D.

    2010-05-05

    The Heavy Water Components Test Reactor (HWCTR) facility (Figure 1) was built in 1961, operated from 1962 to 1964, and is located in the northwest quadrant of the Savannah River Site (SRS) approximately three miles from the site boundary. The HWCTR facility is on high, well-drained ground, about 30 meters above the water table. The HWCTR was a pressurized heavy water test reactor used to develop candidate fuel designs for heavy water power reactors. It was not a defense-related facility like the materials production reactors at SRS. The reactor was moderated with heavy water and was rated at 50 megawatts thermal power. In December of 1964, operations were terminated and the facility was placed in a standby condition as a result of the decision by the U.S. Atomic Energy Commission to redirect research and development work on heavy water power reactors to reactors cooled with organic materials. For about one year, site personnel maintained the facility in a standby status, and then retired the reactor in place. In 1965, fuel assemblies were removed, systems that contained heavy water were drained, fluid piping systems were drained, deenergized and disconnected and the spent fuel basin was drained and dried. The doors of the reactor facility were shut and it wasn't until 10 years later that decommissioning plans were considered and ultimately postponed due to budget constraints. In the early 1990s, DOE began planning to decommission HWCTR again. Yet, in the face of new budget constraints, DOE deferred dismantlement and placed HWCTR in an extended surveillance and maintenance mode. The doors of the reactor facility were welded shut to protect workers and discourage intruders. The $1.6 billion allocation from the American Recovery and Reinvestment Act to SRS for site clean up at SRS has opened the doors to the HWCTR again - this time for final decommissioning. During the lifetime of HWCTR, 36 different fuel assemblies were tested in the facility. Ten of these experienced cladding failures as operational capabilities of the different designs were being established. In addition, numerous spills of heavy water occurred within the facility. Currently, radiation and radioactive contamination levels are low within HWCTR with most of the radioactivity contained within the reactor vessel. There are no known insults to the environment, however with the increasing deterioration of the facility, the possibility exists that contamination could spread outside the facility if it is not decommissioned. An interior panoramic view of the ground floor elevation taken in August 2009 is shown in Figure 2. The foreground shows the transfer coffin followed by the reactor vessel and control rod drive platform in the center. Behind the reactor vessel is the fuel pool. Above the ground level are the polar crane and the emergency deluge tank at the top of the dome. Note the considerable rust and degradation of the components and the interior of the containment building. Alternative studies have concluded that the most environmentally safe, cost effective option for final decommissioning is to remove the reactor vessel, steam generators, and all equipment above grade including the dome. Characterization studies along with transport models have concluded that the remaining below grade equipment that is left in place including the transfer coffin will not contribute any significant contamination to the environment in the future. The below grade space will be grouted in place. A concrete cover will be placed over the remaining footprint and the groundwater will be monitored for an indefinite period to ensure compliance with environmental regulations. The schedule for completion of decommissioning is late FY2011. This paper describes the concepts planned in order to remove the major components including the dome, the reactor vessel (RV), the two steam generators (SG), and relocating the transfer coffin (TC).

    As a means of lowering greenhouse gas emissions, increasing economic growth, and reducing the dependency on imported oil, the Department of Energy and Brookhaven National Laboratory (DOE/ BNL) is promoting the substitution of liquefied natural gas (LNG) in heavy-vehicles that are currently being fueled by diesel. Heavy vehicles are defined as Class 7 and 8 trucks (> 118,000 pounds GVVV), and transit buses that have a fuel usage greater than 10,000 gallons per year and driving range of more than 300 miles. The key in making LNG market-competitive with all types of diesel fuels is in improving energy efficiency and reducing costs of LNG technologies through systems integration. This paper integrates together the three LNG technologies of: (1) production from landfills and remote well sites; (2) cryogenic fuel delivery systems; and (3) state-of-the-art storage tank and refueling facilities, with market end-use strategies. The program's goal is to develop these technologies and strategies under a ''green'' and ''clean'' strategy. This ''green'' approach reduces the net contribution of global warming gases by reducing levels of methane and carbon dioxide released by heavy vehicles usage to below recoverable amounts of natural gas from landfills and other natural resources. Clean technology refers to efficient use of energy with low environmental emissions. The objective of the program is to promote fuel competition by having LNG priced between $0.40 - $0.50 per gallon with a combined production, fuel delivery and engine systems efficiency approaching 45%. This can make LNG a viable alternative to diesel.

  16. Characterization of heavy oil by capillary supercritical fluid chromatography

    The characterization of heavy oils and bitumen produced by thermal recovery methods may aid in bringing about the following benefits: improved recovery methods, promotion of upgrading in the reservoir, improved emulsion treatment and optimized use of diluent for transportation. Because of the high proportion of nonvolatile compounds in heavy oils, gas chromatography (GC) is not particularly useful for characterization purposes. High performance liquid chromatography, while capable of analyzing a larger proportion of the nonvolatiles, possesses considerably less resolution than GC. By utilizing mobile phases in their supercritical region it is possible to study compounds that cannot be vaporized for GC analysis, yet still attain the resolution approaching that of GC. Another advantage of supercritical fluid chromatography (SFC) with the commonly used mobile phase CO/sub 2/, is the ability to employ the flame ionization detector (FID) which provides a uniform response over a wide range of compound types. SFC methods used on packed columns are excellent for low resolution separations into hydrocarbon group types and can produce data in about 5 to 15 min. A number of workers have described the use of packed silica columns for the separation and quantitation of saturate and aromatic component types in gasolines and middle distillate fuels, and of saturates, aromatics and polars in high boiling residues. In these studies the mobile phase was CO/sub 2/ and the detector was the FID. Campbell and Lee reported a semi-preparative SFC method using a packed, amino-modified silica column for the separation of aromatics according to the number of rings in a coal tar and a solved refined coal heavy distillate.

    The design of stormwater wetlands and ponds as wildlife habitats has prompted concern over the potential uptake of runoff contaminants by aquatic fauna. Stormwater wetlands provide a diverse array of habitat for aquatic macroinvertebrates. The importance of macroinvertebrates in aquatic communities has been well documented. Aquatic macroinvertebrates also serve as a major food source of many aquatic vertebrates, including fish and birds. The objectives of the study were to: (1) examine the responses of the macroinvertebrate community to water and sediment concentrations of heavy metals, and other water quality parameters; (2) determine whether macroinvertebrates living in stormwater wetlands bioaccumulate significant concentrations of heavy metals; (3) relate the concentrations of heavy metals in sediment, water and macroinvertebrates to land use in the surrounding watershed; (4) determine sediment and water toxicity to macroinvertebrates. Twenty stormwater wetlands, representing four land uses commercial, residential, highway and control, were monitored in this study. Water quality parameters, including pH, DO, turbidity, conductivity, hardness and metal concentrations were monitored bi-weekly for six months. Sediment samples were collected three times during the same period. Macroinvertebrate communities were sampled during alternate weeks after water collections. Ten-day sediment bioassays were conducted using the amphipod Hyalella azteca. Preliminary data analyses have indicated no significant difference in sediment and water metal concentrations between land uses. However, Zn concentrations in macroinvertebrates were significantly higher (p < 0.05) in wetlands serving commercial watersheds than in those serving the remaining three land uses. No differences have been detected in composition of invertebrate communities due to land use category.

    We formulate an effective theory for systems containing a heavy Majorana fermion, such as bound states of a long-lived gluino. This 'Majorana HQET' has the same degrees of freedom as the well-studied Dirac HQET. It respects an emergent U(1) symmetry despite the fundamental absence of a U(1) for Majorana fermions. Reparametrization invariance works identically in the two HQETs. Remarkably, while a Dirac HQET may or may not be charge conjugation symmetric, a charge conjugation symmetry emerges in all Majorana HQETs, potentially offering low energy probes to distinguish the two theories.

    The present invention is a bi-thermal membrane process for separating and recovering hydrogen isotopes from a fluid containing hydrogen isotopes, such as water and hydrogen gas. The process in accordance with the present invention provides counter-current cold and hot streams of the fluid separated with a thermally insulating and chemically transparent proton exchange membrane (PEM). The two streams exchange hydrogen isotopes through the membrane: the heavier isotopes migrate into the cold stream, while the lighter isotopes migrate into the hot stream. The heavy and light isotopes are continuously withdrawn from the cold and hot streams respectively.

    Solids removal in coprocessing by filtration rather than vacuum distillation offers possibilities of altering process products and their yields (for example, a clean ash free pitch or coke could be produced). Samples of heavy ends from the CANMET process have been tested in a series of small-scale laboratory filtration tests, in which rates were measured and specific cake resistivities subsequently calculated. The effects of feed pre-concentration, filter pressure and addition of carbon filter aid air reported. The results indicate that the removal of solids from this feedstock by filtration is technically and economically feasible.

    Improvements in Heavy oils conversion imply sulfur compounds. For medium conversion, side polycondensations and coke production were avoided by Hydrogen diluent donors (HDD), but conversions were partially inhibited. Sulfided radical activators used in association with HDD and H{sub 2} pressure overcome this effect by preventing coke formation up to 50-60% conversion into 500{degrees}C{sup -} light fractions with unchanged quality profile. Deeper conversions require dispersed sulfided catalyst. Phosphomolybdic acid or molybdenum naphtenate have been used as soluble precursors for such treatments. The state and fitness of sulfidation depend on the nature of precursors.

    The tar sand deposits in the State of Alabama contain about 1.8 billion barrels of measured and more than 4 billion barrels of speculative in-place bitumen. A comprehensive research program is in progress for the separation of bitumen from these deposits. In general, Alabama tar sands are oil wetted, low grade and highly viscous in nature. In view of these facts, a beneficiation strategy has been developed to recover bitumen enriched concentrate which can be used as a feed material for further processing. Heavy liquid separation tests and results are discussed. A 77% zinc bromide solution, specific gravity of 2.4, was used for the tests. 2 figures.

    The objective of this applied research effort led by Georgia Tech Research Institute is the application of pneumatic aerodynamic technology previously developed and patented by us to the design of an appropriate Heavy Vehicle (HV) tractor-trailer configuration, and experimental confirmation of this pneumatic configuration's improved aerodynamic characteristics. In Phases I to IV of our previous DOE program (Reference 1), GTRI has developed, patented, wind-tunnel tested and road-tested blown aerodynamic devices for Pneumatic Heavy Vehicles (PHVs) and Pneumatic Sports Utility Vehicles (PSUVs). To further advance these pneumatic technologies towards HV and SUV applications, additional Phase V tasks were included in the first year of a continuing DOE program (Reference 2). Based on the results of the Phase IV full-scale test programs, these Phase V tasks extended the application of pneumatic aerodynamics to include: further economy and performance improvements; increased aerodynamic stability and control; and safety of operation of Pneumatic HVs. Continued development of a Pneumatic SUV was also conducted during the Phase V program. Phase V was completed in July, 2003; its positive results towards development and confirmation of this pneumatic technology are reported in References 3 and 4. The current Phase VI of this program was incrementally funded by DOE in order to continue this technology development towards a second fuel economy test on the Pneumatic Heavy Vehicle. The objectives of this current Phase VI research and development effort (Ref. 5) fall into two categories: (1) develop improved pneumatic aerodynamic technology and configurations on smaller-scale models of the advanced Pneumatic Heavy Vehicle (PHV); and based on these findings, (2) redesign, modify, and re-test the modified full-scale PHV test vehicle. This second objective includes conduct of an on-road preliminary road test of this configuration to prepare it for a second series of SAE Type-U fuel economy evaluations, as described in Ref. 5. Both objectives are based on the pneumatic technology already developed and confirmed for DOE OHVT/OAAT in Phases I-V. This new Phase VI effort was initiated by contract amendment to the Phase V effort using carryover FY02 funds. This were conducted under a new and distinct project number, GTRI Project A-6935, separate from the Phase I-IV program. However, the two programs are closely integrated, and thus Phase VI continues with the previous program and goals.

    Coal, bitumen and heavy oil (and various pitches, resids, etc.) are similar in that they require more substantial treatment than does conventional light oil to yield useful liquid fuels. The authors provide a brief and selective review of technologies for liquefying coal, followed by consideration of co-processing coal with bitumen/heavy oil. Such co-processing may be considered as use of bitumen/heavy oil as a solvent and/or hydrogen donor in liquefaction of coal, or as the use of coal to aid upgrading bitumen/heavy oil.

    An object of the present invention is to provide a method for separating and recovering hydrogen isotopes that avoids the disadvantages of the prior art, is more simple, and allows for continuous hydrogen isotope separation and recovery. The disclosed invention does not require the use of isotope exchange reaction catalysts and/or hydrogen sulfide gas. The present invention achieves the advantages of the thermal diffusion and the chemical exchange processes. The disclosed invention provides a method for separating and recovering hydrogen isotopes from a fluid containing the hydrogen isotopes by providing counter-current cold and hot streams of the fluid containing the hydrogen isotopes separated by a proton exchange membrane made of thermally insulating and chemically transparent material that allows exchange of heavy and light hydrogen isotopes there through. The heavier isotopes migrate to the cold stream producing a deuterium and tritium-enriched fluid, while lighter isotopes migrate to the hot stream producing a lighter isotope-enriched fluid. The heavy and light isotopes are withdrawn from the cold and hot streams respectively. According to the present invention, the fluid is water or hydrogen gas, and the desired hydrogen isotope species are deuterium and/or tritium. Further, according to the present invention, the streams of said high and low temperature fluids are interconnected at their respective top and bottom ends forming a continuous loop, and a feed stream is provided at an intermediate portion of either hot or cold stream to feed the process.

    Swift heavy ion induced radiation damage is investigated for ceria (CeO2), which serves as a UO2 fuel surrogate. Microstructural changes resulting from an irradiation with 940 MeV gold ions of 42 keV/nm electronic energy loss are investigated by means of electron microscopy accompanied by electron energy loss spectroscopy showing that there exists a small density reduction in the ion track core. While chemical changes in the ion track are not precluded, evidence of them was not observed. Classical molecular dynamics simulations of thermal spikes in CeO2 with an energy deposition of 12 and 36 keV/nm show damage consisting of isolatedmore » point defects at 12 keV/nm, and defect clusters at 36 keV/nm, with no amorphization at either energy. Furthermore, inferences are drawn from modeling about density changes in the ion track and the formation of interstitial loops that shed light on features observed by electron microscopy of swift heavy ion irradiated ceria.« less

  18. Comparison of Muon Capture in Light and in Heavy Nuclei

    SciTech Connect (OSTI)

    Measday, David F.; Stocki, Trevor J.

    2007-10-26

    We have recently completed an experimental study at TRIUMF of muon capture in the following elements, N, Al, Si, Ca, Fe, Ni, I, Au, and Bi. We detected the nuclear gamma rays emitted by the product nuclei after muon capture. The energy of the gamma ray identifies the source nuclide, and thus the reaction which has occurred. Our data are of better quality, and more comprehensive than any other data set in the literature. The ({mu}{sup -},{nu}n) reaction is always dominant. In light nuclei, reactions such as ({mu}{sup -},{nu}p) and ({mu}{sup -},{nu}pn) can occur, but not for heavy nuclei. However the reverse is true for reactions such as ({mu}{sup -},{nu}3n) and ({mu}{sup -},{nu}4n), which are very rare in light nuclei, but easily detected in heavy elements. We shall discuss how such information can be useful in calculations of neutrino-nucleus interactions, and of electron-capture in supernovae.

  19. Heavy-fermion instability in double-degenerate plasmas

    Akbari-Moghanjoughi, M.

    2012-07-15

    In this work, we study the propagations of normal frequency modes for quantum hydrodynamic waves in the linear limit and introduce a new kind of instability in a double-degenerate plasma. Three different regimes, namely, low, intermediate, and high magnetic field strengths are considered which span the applicability of the work to a wide variety of environments. Distinct behavior is observed for different regimes, for instance, in the laboratory-scale field regime no frequency-mode instability occurs unlike those of intermediate and high magnetic-field strength regimes. It is also found that the instability of this kind is due to the heavy-fermions which appear below a critical effective-mass parameter ({mu}{sub cr}={radical}(3)) and that the responses of the two (lower and upper frequency) modes to fractional effective-mass change in different effective-mass parameter ranges (below and above the critical value) are quite opposite to each other. It is shown that the heavy-fermion instability due to extremely high magnetic field such as that encountered for a neutron-star crust can lead to confinement of stable propagations in both lower and upper frequency modes to the magnetic poles. Current study can have important implications for linear wave dynamics in both laboratory and astrophysical environments possessing high magnetic fields.

  20. Radiative corrections from heavy fast-roll fields during inflation

    SciTech Connect (OSTI)

    2015-06-09

    We investigate radiative corrections to the inflaton potential from heavy fields undergoing a fast-roll phase transition. We find that a logarithmic one-loop correction to the inflaton potential involving this field can induce a temporary running of the spectral index. The induced running can be a short burst of strong running, which may be related to the observed anomalies on large scales in the cosmic microwave spectrum, or extend over many e-folds, sustaining an effectively constant running to be searched for in the future. We implement this in a general class of models, where effects are mediated through a heavy messenger field sitting in its minimum. Interestingly, within the present framework it is a generic outcome that a large running implies a small field model with a vanishing tensor-to-scalar ratio, circumventing the normal expectation that small field models typically lead to an unobservably small running of the spectral index. An observable level of tensor modes can also be accommodated, but, surprisingly, this requires running to be induced by a curvaton. If upcoming observations are consistent with a small tensor-to-scalar ratio as predicted by small field models of inflation, then the present study serves as an explicit example contrary to the general expectation that the running will be unobservable.

    1982-09-01

    The method is a moderate-pressure, noncatalytic alternative which has been shown to be applicable to a wide range of bitumens and heavy oils. It offers the potential of efficiency and reliability at a low capitalized investment and operating cost. The raw distillates are separated from the bitumen or heavy oil and the vacuum residuum is blended with an efficient hydrogen donor stream containing a high proportion of substituted tetralins, and is thermally cracking in the liquid phase. The exhausted donor is recovered from the middle distillate reactor product, reactivated by fixed bed hydrogenation before being recycled to the reactor. The process can be self-sufficient in donor and is independent of the metal content of the feed. The products are blanded with the raw distillates and further hydrogenated to high quality petroleum products. While the primary hydrogen consumption is low, the reconstituted naphtha, distillate and gas oil fractions require less hydrogen than the coker liquids to achieve acceptable refinery feed quality. 1 figure, 9 tables.

    The research and development center of Chiyoda Chemical Engineering and Construction Co. has been investigating the catalytic hydrotreating of heavy residua via pilot plant technology. Chiyoda's 52 microreactors. bench-scale test units and pilot plants are each used depending on the purpose of the process development for heavy oil upgrading. The microreactors are effective for catalyst screening. Heavier fractions such as asphaltene and sludge materials often disturbed steady state operation. Many unique devices for the test units and improvement of operation procedures make extended operation easy as well as increasing reliability. The computerized data acquisition and data filing systems minimize the work not only for operators but for all research personnel. Currently, about 40 pilot plant units are continuously running while the others are in preparation. Fully automated operation requires only three for data checking at night. In the daytime, seven operators take care of feed supply, product removal and condition changes. For start-up and shut-down, one operator can handle three microreactos, but only one bench-scale unit or pilot plant. Planning is underway for an improved start-up system for the pilot plants using personal computers. This system automatically sets feed rate and raises reactor temperature. (JMT)

    We use extended x-ray adsorption fine structure (EXAFS) spectroscopy to examine the chemical environment of zinc (1-2 wt. %), lead (300-600 ppm) and cadmium (50-200 ppm) in complex acid mine drainage sediments from the Tri-State Mining District (KS, MO, OK). The sediments in streams draining tailings piles and open mine shafts are dominated by quartz or amorphous iron hydroxides; accessory minerals include calcite. The bulk water chemistry is buffered by the limestone geology and is undersaturated with respect to pure heavy metal carbonates and hydroxides. EXAFS spectra of the sediment samples were taken at SSRL with a fluorescence detector at low temperature ({approximately}10 K). Heavy metals do not form pure carbonate or hydroxide phases, nor do they appear to sorb to quartz surfaces. In sediments near the mine source, the metals are present primarily as sulfides, the original host mineral. With increasing distance from the source, second-neighbor backscattering from Fe indicates that the metals leached from the sulfides are taken up with amorphous iron hydroxides.

    We show that the single, nonphotonic electron nuclear modification factor R{sub AA}{sup e} is affected by the thermal enhancement of the heavy-baryon-to-heavy-meson ratio in relativistic heavy-ion collisions with respect to proton-proton collisions. We make use of the dynamical quark recombination model to compute such a ratio and show that this produces a sizable suppression factor for R{sub AA}{sup e} at intermediate transverse momenta. We argue that this suppression factor needs to be considered, in addition to the energy loss contribution, in calculations of R{sub AA}{sup e}.

    Multi Module Model is required for the realistic and detailed description of an ultrarelativistic heavy ion reaction. We are working in the framework of such a model: initial stages are described by Effective String Rope Model with expanding final streaks; hydrodynamical approach is used for the intermediate stages. This paper is mainly devoted to Third Module - the one dealing with Freeze Out (FO). Two possibilities are discussed in details: (A) freeze out at the constant time hypersurface, where the statistical production model is used to describe post FO particle species; and (B) simultaneous hadronization and freeze out from supercooled QGP. For the last case the ALCOR-like algorithm for calculation of the post FO particle species is presented, due to the fact that these do not have time to reach chemical equilibrium.

    Earlier experiments suggested that large differences in heat release between the two sides of a palladium electrode coated with gold on one side and manganese oxide on the other cause observed electrode deformation with high-pressure D{sub 2} gas loading in an electrolysis-like cell. Similar experiments were repeated using heavy water electrolysis. Palladium/titanium coatings on one side and gold coating on the other were made for the preparation of the palladium electrodes. Biaxial bending, partial discoloration, and microcracks of palladium electrodes were observed after 18 days of electrolysis. Analysis of the deformed palladium cathodes was performed. It was discovered that to convert this configuration to a practical energy-producing cell, a coating technique must be found to reduce outward diffusion of deuterium, i.e., to maintain a high D/Pd ratio over longer periods of time. 33 refs., 7 figs., 1 tab.

    The Siberian snakes are powerful tools in preserving polarization in high energy accelerators has been demonstrated at the Brookhaven Relativistic Heavy Ion Collider (RHIC). Equipped with two full Siberian snakes in each ring, polarization is preserved during acceleration from injection to 100 GeV. However, the Siberian snakes also introduce a new set of depolarization resonances, i.e. snake resonances as first discovered by Lee and Tepikian. The intrinsic spin resonances above 100 GeV are about a factor of two stronger than those below 100 GeV which raises the challenge to preserve the polarization up to 250 GeV. In 2009, polarized protons collided for the first time at the RHIC design store energy of 250 GeV. This paper presents the experimental measurements of snake resonances at RHIC. The plan for avoiding these resonances is also presented.

    Heavy metal movement in soil profiles is a major environmental concern because even slow transport through the soil may eventually lead to deterioration of groundwater quality. In this study, three metal-contaminated soil (Fuquay, Dothan, and Clarendon) were selected from cropland were a high-metal flue dust had been applied annually for 6 years to raise soil pH, with application ending 4 years before sampling. One uncontaminated soil (Tifton) from the same physiographic area was also sampled as a control. Soil samples were collected in 15-cm increments from the surface to 105 cm in depth. Total contents of Zn, Cd, and Pb in the soils samples were determined. To better understand metal movement in relation to metal fractions in the soil profile, soil samples were also extracted sequentially for exchangeable (EXC), organic matter (OM), Mn oxide (MNO), amorphous Fe oxide (AFEO), crystalline Fe oxide (CFEO), and residual (RES) fractions. 35 refs., 6 figs., 2 tabs.

    The catalyst deactivation in the repeated hydrotreatments of asphaltene in petroleum residues, coal liquids and their mixture was comparatively studied in the single- and two-stage reactions, using the same commercial Ni-Mo/Al{sub 2}O{sub 3} catalysts in the batch autoclave. The less catalyst deactivation as well as higher performances in the denitrogenation (>80%) and upgrading of coal liquid were obtained in the two-stage hydrotreatment of 390{degree}C-2h and 430{degree}C-2h. The increase of the catalyst weight which causes the decrease of the activity was considerably less in the two-stage reaction. The two-stage hydrotreatment, which allows a combination of best catalysts in the respective stages under most appropriate conditions for their best performances, can be further effective in the upgrading of heavy residual hydrocarbons.

    Although the primary objectives of heavy oil in situ pilots are reservoir oriented in terms of production rate and recovery efficiency, considerable development of surface engineering technology is a necessary aspect of pilot operations. Esso's basic design philosophy is to use state-of-the-art technology with onsite operator interaction to sequentially develop improvements in surface equipment and processes without comprising reservoir based research objectives. This work reviews Esso's operating experience and technical developments in pilot design at Cold Lake, Alta. The considerations which led to the design basis for the Cold Lake commercial project are examined in the areas of well layout, steam and production distribution system design, oil and water separation, and produced water treatment.

    1987-04-01

    In comparison with ordinary oil, tar sands bitumen and vacuum residue contain large quantities of impurities such as asphaltene, heavy metal compounds, sulfur, and nitrogen, which are obstacles to upgrading the refining process. Therefore, these types of materials are extremely difficult to treat with existing refining technologies. In order to upgrade oil feedstocks that are of poor quality, such as tar sands bitumen, new upgrading technologies must be established. In this paper, the author discusses first, the results of catalyst screening, second, the factors of the active catalyst, and finally, the performance of a semi-industrially produced catalyst. The catalyst has high middle-distillate yield, coke plus gum (coke precursors) suppressing ability, low hydrogen consumption and mechanical strength and high temperature stability in slurry reactors.

    1995-12-31

    The value of abundant, low-grade heavy crude oil reserves can be enhanced by appropriate upgrade processing at the production site to yield marketable refinery feedstocks or ultimate products. One of the upgrading process sequences most commonly considered involves vacuum distillation followed by a bottoms processing step such as solvent deasphalting or coking. These schemes can be further enhanced with the addition of a gasification step to convert the unsaleable, bottom-of-the-barrel residues into useful products, such as high-purity hydrogen for hydrotreating, electrical power, steam for enhanced oil recovery and distillation, etc. This paper describes the Texaco Gasification Process and the T-STARs hydrotreating process, and their application in an integrated upgrade processing scheme in which an optimal, virtually bottomless oil utilization can be achieved. Illustrative examples of this integration are provided with comparative economic information.

    The Dynacracking process developed by Hydrocarbon Research, Inc., is a non-catalytic process capable of upgrading heavy oil whose sulfur, metal, and carbon contents may be high. It converts residual stocks to distillates with high naphtha yields, and to synthetic fuel gas of high quality (700-800 Btu/ft/sup 3/). It has esentially no air polution emissions and requires a relatively small amount of water and utilities. The process generates sufficient heat internally such that, except for start-up, no boilers, furnaces, or external heaters are required to operate the plant. Several aspects of the process are discussed: chemistry, hardware, feedstock, flexibility in the product mix, product quality, and economics.

    Beginning in 1983, Esso Resources Canada Ltd. will begin drilling the first of an estimated 9000 directional crude bitumen wells in the tar sands at Cold Lake, Alberta, Canada, the final wells being drilled in the year 2008. The area, covering 50 sq miles of extreme E. Alberta along the Saskatchewan border, contains one of the richest deposits of heavy oil sands in Canada. The company and future partners will drill the bitumen wells directionally into the shallow clearwater formation, which can be reached at approx. 100 m (330 ft). The formation contains an estimated 80 billion bbl of crude bitumen at a rate of 60,000 bpd for 25 yr. This volume of crude will be refined in an upgrading plant to 140,000 bpd of synthetic crude oil. When completed, the Cold Lake project will be one of the largest facilities for producing crude bitumen from wells in the world.

    As described in its multiyear program plan for 1998-2000, the Office of Heavy Vehicle Technologies (OHVT) envisions the development of a fuel-flexible, energy-efficient, near-zero-emissions, heavy-duty U.S. diesel engine technology devolving into all truck classes as a real and viable strategy for reducing energy requirements for commercial transport services and the rapidly growing multipurpose vehicle market (pickups, vans, and sport utility vehicles). Implementation of the OHVT program plan will have significant national benefits in energy savings, cleaner air, more jobs, and increased gross domestic product (GDP). Successful implementation will reduce the petroleum consumption of Class 1-8 trucks by 1.4 million barrels of oil per day by 2020 and over 1.8 million by 2030, amounting to a reduction in highway petroleum consumption of 13.2% and 18.6%, respectively. All types of regulated emissions will be reduced, that is, 20% drop in PM10 emissions (41,000 metric tons per year) by 203 0, 17% reduction in CO2 greenhouse gases (205 million metric tons per year), 7% reduction in NOx, 20% reduction in NMHC, and 30% reduction in CO. An increase of 15,000 jobs by 2020 is expected, as is an increase of $24 billion in GDP. The strategy of OHVT is to focus primarily on the diesel engine since it has numerous advantages. It has the highest efficiency of any engine today, 45% versus 30% for production gasoline engines; and it can be made more efficient at least to 55% and possibly up to 63%. It is the engine of choice for heavy vehicles (trucks), because it offers power, efficiency, durability, and reliability and is used extensively in rail, marine, and off-road applications. Its emission can be ultra-low to near zero, and the production infrastructure is already in place. The primary goals of OHVT are as follows: (1) Develop by 2002 the diesel-engine enabling technologies to support large-scale industry dieselization of light trucks, achieving a 35% fuel efficiency improvement over equivalent gasoline-fueled trucks. (2) Develop by 2004 the enabling technology for a Class 7-8 truck with a fuel efficiency of 10 mpg (at 65 mph) that will meet prevailing emission standards, using either diesel or a liquid alternative fuel. (3) Develop by 2006 diesel engines with fuel flexibility and a thermal efficiency of 55% with liquid alternative fuels, and a thermal efficiency of 55% with dedicated gaseous fuels. (4) Develop a methodology for analyzing and evaluating the operation of a heavy vehicle as an integrated system, considering such factors as engine efficiency; emissions; rolling resistance; aerodynamic drag; friction, wear, and lubrication effects; auxiliary power units; material substitutions for reducing weight; and other sources of parasitic energy losses. Overarching these considerations is the need to preserve system functionality, cost, competitiveness, reliability, durability, and safety.

    The Relativistic Heavy Ion Collider (RHIC) at Brookhaven National Laboratory has been operating since 2000. Over the past decade, thanks to the continuously increased bunch intensity and reduced β*s at the interaction points, the maximum peak luminosity in the polarized proton operation has been increased by more than two orders of magnitude. In this article, we first present the beam-beam observations in the previous RHIC polarized proton runs. Then we analyze the mechanisms for the beam loss and emittance growth in the presence of beam-beam interaction. The operational challenges and limitations imposed by beam-beam interaction and their remedies are also presented. In the end, we briefly introduce head-on beam-beam compensation with electron lenses in RHIC.

    We are developing techniques for imaging beams in heavy-ion beam fusion experiments in the HIF-VNL in 2 to 4 transverse dimensions. The beams in current experiments range in energy from 50 keV to 2 MeV, with beam current densities from <10 to 200 mA/cm{sup 2}, and pulse lengths of 4 to 20 {micro}s. The beam energy will range up to 10 MeV in near-future beam experiments. The imaging techniques, based on kapton films and optical scintillators, complement and, in some cases, may replace mechanical slit scanners. The kapton film images represent a time-integrated image on the film exposed to the beam. The optical scintillator utilizes glass and ceramic scintillator material imaged by a fast, image-intensified CCD-based camera. We will discuss the techniques, results, and plans for implementation of the diagnostics on the beam experiments.

    This volume contains reservoir, production, and project data for target reservoirs thermally recoverable by steam drive which are equal to or greater than 2500 feet deep and contain heavy oil in the 8 to 25/sup 0/ API gravity range. Data were collected from three source types: hands-on (A), once-removed (B), and twice-removed (C). In all cases, data were sought depicting and characterizing individual reservoirs as opposed to data covering an entire field with more than one producing interval or reservoir. The data sources are listed at the end of each case. This volume also contains a complete listing of operators and projects, as well as a bibliography of source material.

    This report describes the results of a two-year laboratory directed research and development project to explore advanced concepts in Heavy Ion Backscattering Spectrometry (HIBS), undertaken with the goal of extending the sensitivity of this relatively new technique to levels unattainable by any other existing trace element surface analysis. Improvements in sensitivity are required for the application of HIBS to contamination control in the microelectronics industry. Tools with sensitivity approaching 10{sup 8} atoms/cm{sup 2} are expected to be essential for enabling advanced IC production by the year 2000. During the project the authors developed a new analysis chamber with channeling goniometer and a prototype time-of-flight detector with a demonstrated sensitivity of {approximately} 5 {times} 10{sup 8} atoms/cm{sup 2} for Au on Si and {approximately} 5 {times} 10{sup 10} for Fe, and sufficient mass resolution to separate contributions from Fe and Cu.

    Using the two-component model that includes charmonium production from both initial nucleon-nucleon hard scattering and regeneration in the produced quark-gluon plasma, we study J/{psi} production in heavy-ion collisions at the Super Proton Synchrotron (SPS), Relativistic Heavy Ion Collider (RHIC), and Large Hadron Collider (LHC). For the expansion dynamics of produced hot dense matter, we use a schematic viscous hydrodynamic model with the specific shear viscosity in the quark-gluon plasma and the hadronic matter taken, respectively, to be two and ten times the lower bound of 1/4{pi} suggested by the anti-de Sitter/conformal field theory (AdS/CFT) correspondence. For the initial dissociation and the subsequent thermal decay of charmonia in the hot dense matter, we use the screened Cornell potential to describe the properties of charmonia and perturbative QCD to calculate their dissociation cross sections. Including regeneration of charmonia in the quark-gluon plasma via a kinetic equation with in-medium chamonium decay widths, we obtain a good description of measured J/{psi} nuclear modification factors in Pb + Pb collisions at {radical}(s{sub NN})=1.73 GeV at SPS and in Au + Au collisions at {radical}(s{sub NN})=200 GeV at RHIC. A reasonable description of the measured nuclear modification factor of high transverse momenta J/{psi} in Pb + Pb collisions at {radical}(s{sub NN})=2.76 TeV at LHC is also obtained.

    1991-01-01

    This paper reports on the sporadic nature of the excess heat reported from heavy water electrolysis which has attributed to variability among the different palladium cathodes used. Experimental repeatability should, therefore, be enhanced if the microstructure of the palladium can be controlled. Toward this end, palladium rod samples from two heavy water electrolysis experiments were compared to a sample representative of the as-installed condition. The samples examined showed equiaxed grains and significant abnormal grain growth. The rod axes had strong textures, which were attributed to their prior thermomechanical history. The postelectrolysis palladium rods were sampled at two locations that were suspected to have operated at different average current densities. The suspected higher current density regions consisted of single-phase Pd-D{sub 0.7} microstructures. Surface-originated cracks were seen along the grain boundaries in one of two such specimens. Cracks were absent in samples from the suspected lower current density regions, which showed two-phase microstructures with Pd-D{sub 0.7} as the dominant phase. The minor phase, indexed as palladium in the X-ray pattern, was dispersed nonuniformly, mostly in the form of stringers, across the grain boundaries. It is concluded that high current densities resulted in high deuterium loadings in palladium. Smoothing effects from the electrolytic process, resulting in preferential material removal from the grain boundaries, were seen on the cathode surface. A number of high-mass impurities were seen to have deposited on the exposed surface. An initial secondary ion mass spectrometry examination of the specimen interior indicated a significant presence of mass 2 species and considerably lower concentrations of mass 3 and 4 species. Repeat analyses failed to confirm the presence of the mass 3 and 4 species.

    The great majority of the known nuclides with Z>40, including the so-called stable nuclides, are metastable with respect to several modes of spontaneous superasymmetric splitting. A model extended from the fission theory of alpha decay allows one to estimate the lifetimes and the branching ratios relative to the alpha decay for these natural radioactivities. From a huge amount of systematic calculations it is concluded that the process should proceed with maximum intensity in the trans-lead nuclei, where the minimum lifetime is obtained from parent-emitted heavy ion combinations leading to a magic (/sup 208/Pb) or almost magic daughter nucleus. More than 140 nuclides with atomic number smaller than 25 are possible candidates to be emitted from heavy nuclei, with half-lives in the range of 10/sup 10/--10/sup 30/ s: /sup 5/He, /sup 8en-dash10/Be, /sup 11,12/B, /sup 12en-dash16/C, /sup 13en-dash17/N, /sup 15en-dash22/O, /sup 18en-dash23/F, /sup 20en-dash26/Ne, /sup 23en-dash28/Na, /sup 23en-dash30/Mg, /sup 27en-dash32/Al, /sup 28en-dash36/Si, /sup 31en-dash39/P, /sup 32en-dash42/S, /sup 35en-dash45/Cl, /sup 37en-dash47/Ar, /sup 40en-dash49/ K, . .Ca, /sup 44en-dash53/ Sc, /sup 46en-dash53/Ti, /sup 48en-dash54/V, and /sup 49en-dash55/ Cr.

    The US heavy ion fusion science program has developed techniques for heating ion-beam-driven warm dense matter (WDM) targets. The WDM conditions are to be achieved by combined longitudinal and transverse space-charge neutralized drift compression of the ion beam to provide a hot spot on the target with a beam spot size of about 1 mm, and pulse length about 1-2 ns. As a technique for heating volumetric samples of matter to high energy density, intense beams of heavy ions are capable of delivering precise and uniform beam energy deposition dE/dx, in a relatively large sample size, and the ability to heat any solid-phase target material. Initial experiments use a 0.3 MeV K+ beam (below the Bragg peak) from the NDCX-I accelerator. Future plans include target experiments using the NDCX-II accelerator, which is designed to heat targets at the Bragg peak using a 3-6 MeV lithium ion beam. The range of the beams in solid matter targets is about 1 micron, which can be lengthened by using porous targets at reduced density. We have completed the fabrication of a new experimental target chamber facility for WDM experiments, and implemented initial target diagnostics to be used for the first target experiments in NDCX-1. The target chamber has been installed on the NDCX-I beamline. The target diagnostics include a fast multi-channel optical pyrometer, optical streak camera, VISAR, and high-speed gated cameras. Initial WDM experiments will heat targets by compressed NDCX-I beams and will explore measurement of temperature and other target parameters. Experiments are planned in areas such as dense electronegative targets, porous target homogenization and two-phase equation of state.

    We calculate the O(α³s) short-distance, QCD collinear-factorized coefficient functions for all partonic channels that include the production of a heavy quark pair at short distances. Thus, this provides the first power correction to the collinear-factorized inclusive hadronic production of heavy quarkonia at large transverse momentum, pT, including the full leading-order perturbative contributions to the production of heavy quark pairs in all color and spin states employed in NRQCD treatments of this process. We discuss the role of the first power correction in the production rates and the polarizations of heavy quarkonia in high-energy hadronic collisions.

    This report is one of a series of publications assessing the feasibility of increasing domestic heavy oil production. Each report covers select areas of the United States. The Appalachian, Black Warrior, Illinois, and Michigan basins cover most of the depositional basins in the Midwest and Eastern United States. These basins produce sweet, paraffinic light oil and are considered minor heavy oil (10{degrees} to 20{degrees} API gravity or 100 to 100,000 cP viscosity) producers. Heavy oil occurs in both carbonate and sandstone reservoirs of Paleozoic Age along the perimeters of the basins in the same sediments where light oil occurs. The oil is heavy because escape of light ends, water washing of the oil, and biodegradation of the oil have occurred over million of years. The Appalachian, Black Warrior, Illinois, and Michigan basins' heavy oil fields have produced some 450,000 bbl of heavy oil of an estimated 14,000,000 bbl originally in place. The basins have been long-term, major light-oil-producing areas and are served by an extensive pipeline network connected to refineries designed to process light sweet and with few exceptions limited volumes of sour or heavy crude oils. Since the light oil is principally paraffinic, it commands a higher price than the asphaltic heavy crude oils of California. The heavy oil that is refined in the Midwest and Eastern US is imported and refined at select refineries. Imports of crude of all grades accounts for 37 to >95% of the oil refined in these areas. Because of the nature of the resource, the Appalachian, Black Warrior, Illinois and Michigan basins are not expected to become major heavy oil producing areas. The crude oil collection system will continue to degrade as light oil production declines. The demand for crude oil will increase pipeline and tanker transport of imported crude to select large refineries to meet the areas' liquid fuels needs.

    2008-03-31

    The objective of this program was to quantify the emissions from heavy-duty vehicles operating on alternative fuels or advanced fuel blends, often with novel engine technology or aftertreatment. In the first year of the program West Virginia University (WVU) researchers determined that a transportable chassis dynamometer emissions measurement approach was required so that fleets of trucks and buses did not need to be ferried across the nation to a fixed facility. A Transportable Heavy-Duty Vehicle Emissions Testing Laboratory (Translab) was designed, constructed and verified. This laboratory consisted of a chassis dynamometer semi-trailer and an analytic trailer housing a full scale exhaust dilution tunnel and sampling system which mimicked closely the system described in the Code of Federal Regulations for engine certification. The Translab was first used to quantify emissions from natural gas and methanol fueled transit buses, and a second Translab unit was constructed to satisfy research demand. Subsequent emissions measurement was performed on trucks and buses using ethanol, Fischer-Tropsch fuel, and biodiesel. A medium-duty chassis dynamometer was also designed and constructed to facilitate research on delivery vehicles in the 10,000 to 20,000lb range. The Translab participated in major programs to evaluate low-sulfur diesel in conjunction with passively regenerating exhaust particulate filtration technology, and substantial reductions in particulate matter were recorded. The researchers also participated in programs to evaluate emissions from advanced natural gas engines with closed loop feedback control. These natural gas engines showed substantially reduced levels of oxides of nitrogen. For all of the trucks and buses characterized, the levels of carbon monoxide, oxides of nitrogen, hydrocarbons, carbon dioxide and particulate matter were quantified, and in many cases non-regulated species such as aldehydes were also sampled. Particle size was also quantified during selected studies. A laboratory was established at WVU to provide for studies which supported and augmented the Translab research, and to provide for development of superior emissions measurement systems. This laboratory research focused on engine control and fuel sulfur issues. In recent years, as engine and aftertreatment technologies advanced, emissions levels were reduced such that they were at or below the Translab detectable limits, and in the same time frame the US Environmental Protection Agency required improved measurement methodologies for engine emissions certification. To remain current and relevant, the researchers designed a new Translab analytic system, housed in a container which can be transported on a semi-trailer. The new system's dilution tunnel flow was designed to use a subsonic venturi with closed loop control of blower speed, and the secondary dilution and particulate matter filter capture were designed to follow new EPA engine certification procedures. A further contribution of the program has been the development of techniques for creating heavy-duty vehicle test schedules, and the creation of schedules to mimic a variety of truck and bus vocations.

    This report is one of a series of publications assessing the feasibility of increasing domestic heavy oil production. Each report covers select areas of the United States. The Permian Basin of West Texas and Southeastern New Mexico is made up of the Midland, Delaware, Val Verde, and Kerr Basins; the Northwestern, Eastern, and Southern shelves; the Central Basin Platform, and the Sheffield Channel. The present day Permian Basin was one sedimentary basin until uplift and subsidence occurred during Pennsylvanian and early Permian Age to create the configuration of the basins, shelves, and platform of today. The basin has been a major light oil producing area served by an extensive pipeline network connected to refineries designed to process light sweet and limited sour crude oil. Limited resources of heavy oil (10`` to 20`` API gravity) occurs in both carbonate and sandstone reservoirs of Permian and Cretaceous Age. The largest cumulative heavy oil production comes from fluvial sandstones of the Cretaceous Trinity Group. Permian heavy oil is principally paraffinic and thus commands a higher price than asphaltic California heavy oil. Heavy oil in deeper reservoirs has solution gas and low viscosity and thus can be produced by primary and by waterflooding. Because of the nature of the resource, the Permian Basin should not be considered a major heavy oil producing area.

    Thorium has lately attracted considerable attention because it is accumulating as a by-product of large scale rare earth mining. The objective of research is to analyze transient behavior of a heavy water cooled thorium breeder that is designed by Tokai University and Tokyo Institute of Technology. That is oxide fueled, PWR type reactor with heavy water as primary coolant. An example of the optimized core has relatively small moderator to fuel volume ratio (MFR) of 0.6 and the characteristics of the core are burn-up of 67 GWd/t, breeding ratio of 1.08, burn-up reactivity loss during cycles of < 0.2% dk/k, and negative coolant reactivity coefficient. One of the nuclear reactor accidents types examined here is Unprotected Transient over Power (UTOP) due to withdrawing of the control rod that result in the positive reactivity insertion so that the reactor power will increase rapidly. Another accident type is Unprotected Loss of Flow (ULOF) that caused by failure of coolant pumps. To analyze the reactor accidents, neutron distribution calculation in the nuclear reactor is the most important factor. The best expression for the neutron distribution is the Boltzmann transport equation. However, solving this equation is very difficult so that the space-time diffusion equation is commonly used. Usually, space-time diffusion equation is solved by employing a point kinetics approach. However, this approach is less accurate for a spatially heterogeneous nuclear reactor and the nuclear reactor with quite large reactivity input. Direct method is therefore used to solve space-time diffusion equation which consider spatial factor in detail during nuclear reactor accident simulation. Set of equations that obtained from full implicit finite-difference method is solved by using iterative methods. The indication of UTOP accident is decreasing macroscopic absorption cross-section that results large external reactivity, and ULOF accident is indicated by decreasing coolant flow. The power reactor has a peak value before reactor has new balance condition. The analysis showed that temperatures of fuel and claddings during accident are still below limitations which are in secure condition.

    This report is one of a series of publications assessing the feasibility/constraints of increasing domestic heavy oil production. Each report covers a select area of the United States. The Midcontinent (Kansas, Nssouri, Oklahoma) has produced significant oil, but contrary to early reports, the area does not contain the huge volumes of heavy oil that, along with the development of steam and in situ combustion as oil production technologies, sparked the area`s oil boom of the 1960s. Recovery of this heavy oil has proven economically unfeasible for most operators due to the geology of the formations rather than the technology applied to recover the oil. The geology of the southern Midcontinent, as well as results of field projects using thermal enhanced oil recovery (TEOR) methods to produce the heavy oil, was examined based on analysis of data from secondary sources. Analysis of the performance of these projects showed that the technology recovered additional heavy oil above what was produced from primary production from the consolidated, compartmentalized, fluvial dominated deltaic sandstone formations in the Cherokee and Forest City basins. The only projects producing significant economic and environmentally acceptable heavy oil in the Midcontinent are in higher permeability, unconsolidated or friable, thick sands such as those found in south-central Oklahoma. There are domestic heavy oil reservoirs in other sedimentary basins that are in younger formations, are less consolidated, have higher permeability and can be economically produced with current TEOR technology. Heavy oil production from the carbonates of central and wester Kansas has not been adequately tested, but oil production is anticipated to remain low. Significant expansion of Midcontinent heavy oil production is not anticipated because the economics of oil production and processing are not favorable.

    The Second International Conference on Heavy Crude and Tar Sands clearly demonstrated that the world has abundant heavy and extra heavy crudes that will sustain the petroleum age for decades. Perhaps even more important for many developed and developing countries is that these resources are widely distributed throughout the world, for deposits are known to exist in at least forty-nine countries. Moreover, the rapid expansion over the last two and a half years of knowledge of the magnitude of these resources suggests there is much more to be added to the world's list of useful energy assets. The current ample supply of crude oil does not appear to have lessened the resolve to develop heavy crude and tar sands. Major industrial countries are eager to develop their heavy oil resources to free themselves from dependence on OPEC and the developing nations hope to reduce their cash outflows for imported oil which they can ill afford. Venezuela and Canada, which both have massive heavy crude reserves, are intent on developing their resources to supplement declining supplies of light oil. Despite the weakening international price of oil, the economics for many heavy crude ventures seem favorable. Statistics quoted at the conference suggest considerable heavy crude production can be brought on stream at costs approaching the finding costs of light conventional crude. At the same time, it has to be acknowledged that those large tar sands projects, like Alberta's multi-billion dollar ventures, are sufficiently marginal that they may be held back by current soft oil demand. This summary report covers the following areas: resources; international cooperation; production; environment; technological developments; upgrading and refining; marketing; and future of heavy crude oil and tar sands.

    A heavy metal poisoned, spent FCC catalyst is treated by chemically impregnating the poisoned catalyst with a new catalytic metal or metal salt to provide an attrition resistant catalyst or sorbent for a different catalytic or absorption processes, such as catalysts for Fischer-Tropsh Synthesis, and sorbents for removal of sulfur gasses from fuel gases and flue-gases. The heavy metal contaminated FCC catalyst is directly used as a support for preparing catalysts having new catalytic properties and sorbents having new sorbent properties, without removing or "passivating" the heavy metals on the spent FCC catalyst as an intermediate step.

    1999-01-08

    The basic mechanisms of metastable phase formation produced under highly non-equilibrium thermodynamic conditions within high-energy particle tracks are investigated. In particular, the possible formation of diamond by heavy-ion irradiation of graphite at ambient temperature is examined. This work was motivated, in part, by earlier studies which discovered nanometer-grain polycrystalline diamond aggregates of submicron-size in uranium-rich carbonaceous mineral assemblages of Precambrian age. It was proposed that the radioactive decay of uranium formed diamond in the fission particle tracks produced in the carbonaceous minerals. To test the hypothesis that nanodiamonds can form by ion irradiation, fine-grain polycrystalline graphite sheets were irradiated with 400 MeV Kr ions. The ion irradiated graphite (and unirradiated graphite control) were then subjected to acid dissolution treatments to remove the graphite and isolate any diamonds that were produced. The acid residues were then characterized by analytical and high-resolution transmission electron microscopy. The acid residues of the ion-irradiated graphite were found to contain ppm concentrations of nanodiamonds, suggesting that ion irradiation of bulk graphite at ambient temperature can produce diamond.

    We report on a calculation of the B*Bπ coupling in lattice QCD. The strong matrix element (Bπ|B*) is directly related to the leading order low-energy constant in heavy meson chiral perturbation theory (HMΧPT) for B mesons. We carry out our calculation directly at the b-quark mass using a non-perturbatively tuned clover action that controls discretization effects of order |pa| and (ma)n for all n. Our analysis is performed on RBC/UKQCD gauge configurations using domain-wall fermions and the Iwasaki gauge action at two lattice spacings of a–1 = 1.729(25) GeV, a–1 = 2.281 (28) GeV, and unitary pion masses down to 290 MeV. We achieve good statistical precision and control all systematic uncertainties, giving a final result for the HMΧPT coupling gb = 0.56(3)stat(7)sys in the continuum and at the physical light-quark masses. Furthermore, this is the first calculation performed directly at the physical b-quark mass and lies in the region one would expect from carrying out an interpolation between previous results at the charm mass and at the static point.

  9. A lower cost development path for heavy ion fusion

    If two features of the inertial fusion process are exploited successfully, they can lead to significantly lower costs for demonstrating the feasibility of commercial electric power production from this source of energy. First, fusion capsule ignition and burn physics is independent of reaction chamber size and hydrodynamically-equivalent capsules can be designed to perform at small yield, exactly as they do at large yield. This means that an integrated test of all power plant components and feasibility tests of various reaction chamber concepts can be done at much smaller sizes (about 1--2 m first wall radius) and much lower powers (tens of MWs) than magnetic fusion development facilities such as ITER. Second, the driver, which is the most expensive component of currently conceived IFE development facilities, can be used to support more than one experiment target chamber/reactor (simultaneously and/or sequentially). These two factors lead to lower development facility costs, modular facilities, and the planning flexibility to spread costs over time or do several things in parallel and thus shorten the total time needed for development of Inertial Fusion Energy (IFE). In this paper the authors describe the general feature of a heavy ion fusion development plan that takes advantage of upgradable accelerators and the ability to test chambers and reactor systems at small scale in order to reduce development time and costs.

  10. Soft collinear effective theory for heavy WIMP annihilation

    2015-01-19

    In a large class of models for Weakly Interacting Massive Particles (WIMPs), the WIMP mass M lies far above the weak scale mW. This work identifies universal Sudakov-type logarithms ~ ? log(2 M / mW) that spoil the naive convergence of perturbation theory for annihilation processes. An effective field theory (EFT) framework is presented, allowing the systematic resummation of these logarithms. Another impact of the large separation of scales is that a long-distance wavefunction distortion from electroweak boson exchange leads to observable modifications of the cross section. Careful accounting of momentum regions in the EFT allows the rigorous disentanglement ofmorethis so-called Sommerfeld enhancement from the short-distance hard annihilation process. The WIMP is described as a heavy-particle field, while the electroweak gauge bosons are treated as soft and collinear fields. Hard matching coefficients are computed at renormalization scale ? ~ 2 M , then evolved down to ? ~ mW, where electroweak symmetry breaking is incorporated and the matching onto the relevant quantum mechanical Hamiltonian is performed. The example of an SU(2)W triplet scalar dark matter candidate annihilating to line photons is used for concreteness, allowing the numerical exploration of the impact of next-to-leading order corrections and log resummation. For M ? 3 TeV, the resummed Sommerfeld enhanced cross section is reduced by a factor of ~ 3 with respect to the treelevel fixed order result.less

    Heavy-ion fusion using an induction linac requires injection of multiple high-current beams from a pulsed electrostatic accelerator at as high a voltage as practical. Los Alamos National Laboratory is developing a 16-beam, 2-MeV, pulsed electrostatic accelerator for Al/sup +/ ions. The ion source will use a pulsed metal vapor arc plasma. A biased grid will control plasma flux into the ion extraction region. This source has achieved a normalized emittance of epsilon/sub n/ < 3.10/sup -7/..pi..-m-rad with Al/sup +/ ions. An 800 kV Marx prototype with a laser fired diverter is being assembled. The ceramic accelerating column sections have been brazed and leak tested. Voltage hold off on a brazed sample was more than doubled by selective removal of the Ticusil braze fillet extending along the ceramic. A scaled test module held 250 kV for 50 ..mu..s, giving confidence that the full module can hold 175 kV per section. The pressure vessel should be received in June 1986. High-voltage testing of a 1 MV column will begin by early 1987.

    The extractability of heavy metals in wastewater sludge undergoing anaerobic digestion was investigated. Using batch laboratory digesters, raw wastewater sludge was anaerobically digested at different raw sludge solids loadings and two temperatures. From each of the laboratory digesters, wastewater sludge was sampled at three day intervals and sequentially separated into seven extraction fractions and analyzed for the metals Cu, Cr, Cd, Fe, Ni, and Pb. The seven step sequential extraction was for metal species: (a) soluble, (b) displaced-exchangeable, (c) adsorbed, (d) organic, (e) carbonate, (f) sulfide-acid soluble, and (g) residual. At the 35/sup 0/C digestion temperature the distribution of metals in the extractant fractions between the raw and anaerobically digested sludges were significantly different. For the 45/sup 0/C digestion temperature the distribution of metals in the raw and digested sludge extractant fractions were different and different compared to the 35/sup 0/C system. The 45/sup 0/C raw sludge showed greater percent metal in the organic and sulfide-acid soluble fraction than the digested sludge. At the 45/sup 0/C anaerobic digestion temperature the percent of raw sludge solids loading in the digester had a greater effect on changes in metal extractability and proposed metal species than the 35/sup 0/C.

    Deployment scenario of heavy water cooled thorium breeder reactor has been studied. We have assumed to use plutonium and thorium oxide fuel in water cooled reactor to produce {sup 233}U which will be used in thorium breeder reactor. The objective is to analysis the potential of water cooled Th-Pu reactor for replacing all of current LWRs especially in Japan. In this paper, the standard Pressurize Water Reactor (PWR) has been designed to produce 3423 MWt; (i) Th-Pu PWR, (ii) Th-Pu HWR (MFR = 1.0) and (iii) Th-Pu HWR (MFR 1.2). The properties and performance of the core were investigated by using cell and core calculation code. Th-Pu PWR or HWR produces {sup 233}U to introduce thorium breeder reactor. The result showed that to replace all (60 GWe) LWR by thorium breeder reactor within a period of one century, Th-Pu oxide fueled PWR has insufficient capability to produce necessary amount of {sup 233}U and Th-Pu oxide fueled HWR has almost enough potential to produce {sup 233}U but shows positive void reactivity coefficient.

    The research presented examines DDT of cylinders of PBX 9501 damaged above 180 C in heavy confinement for 0-3 hours and end-ignited or ramped until self-ignition (cookoff) occurred. Progression of luminous reaction was observed by streak photography through a glass-filled slit running the length of the cylinder. Post-mortem analysis of the steel DDT tubes was also done for correlation with the optical records. Results indicate that repeatable, Type I DDT was observed to occur in hot, thermally damaged PBX 9501 with low levels of porosity. It was demonstrated that multiple parameters affect DDT behavior, most likely in a coupled fashion. These parameters are porosity, ignition temperature and thermal soak duration. Conditions leading up to cookoff were shown to sensitize the HE to DDT by increasing likelihood and decreasing run length. Over the range of porosities (0-37%) and ignition temperatures (180-235 C), run lengths and detonation velocities varied, respectively, from approximately 22-109 mm and 6.0-8.3 mm {micro}s{sup -1}. This work fills a valuable and realistic space in the understanding of high explosive violent reaction, including DDT, in abnormal thermal environments.

    This report covers preliminary design of a heavy oil conversion unit based on HRI's Dynacracking Process. The unit is designed for operation in any of the six cases described in this report. The six cases presented demonstrate the versatility of the unit to process three different feedstocks with different product objectives and at various process conditions while keeping the reactor configuration and design fixed. The reactor incorporated in the design is identical to the one proposed for a plant to be built in Pittsburg, CA., with California Synfuels Research Corporation as the operator. An evaluative study is presented of the product qualities and possible alternatives for product utilization and upgrading. An indicative summary is made of the quality of effluents from the unit. Estimated utilities and operating requirements are presented. Overall plant material balances are included for each of the six cases. Process equipment duty specifications and offsite tankage requirements are provided and a preliminary cost estimate presented.

    The advantages of the CANMET hydrocracking process are: Feed Flexibility - high levels of the main feed contaminants, sulfur, nitrogen and metals do not have a deleterious effect on the process. Hence, a wide range of feedstocks can be upgraded by this process including residuum from conventional crudes; Operability - extended runs indicate that the process will operate continuously with little sensitivity to operational problems even with difficult feedstocks such as Cold Lake and Boscan heavy oil. During extended operation nearly constant pitch conversion and product yields and qualities are obtained; High Distillate Yields - the CANMET Process can produce over 100 vol % distillate, compared to 83 vol % for coking process; Flexibility of Operation - the amount of pitch converted can easily be controlled by adjusting reactor temperature and liquid feed rate. Thus, the required product slate can be obtained by simply changing the operating conditions; Thermal Stability - because the process does not employ an active catalyst, the potential for thermal run-away and development of hot spots is considerably reduced; High Pitch Conversion - the CANMET additive permits sustained controlled and repeatable operation at pitch conversions higher than 90 wt % on a wide range of feedstocks; Reduced Operating Pressure - the action of the additive as a processing aid allows substantial reduction in operating pressure below that for competitive commercial technology; and Efficient Hydrogen Utilization - Since CANMET does not employ an active desulfurizing catalyst, overall hydrogen consumption for a given conversion is low. Almost all of the hydrogen goes to distillate product.

    Earlier it was found that various oil-soluble phosphorous compounds were active for vanadium removal from different crude oils. The phosphorous compounds preferentially reacted with low molecular weight vanadium species in the resin fraction and therefore the highest rate of vanadium removal was observed when the asphaltene fraction was partially or completely removed. Phosphorous compounds promoted the rate of vanadium removal during hydroprocessing over alumina in a trickle bed reactor. Some metal phosphates were prepared and tested for demetallization activity. Several mixed metal phosphates, such as Cr-Zr, Ni-Zr, Cu-Zr, V-Co-Zr, Fe-Co-Zr, Ni-Co-Zr, etc., exhibited high activity for both vanadium and nickel removal. These catalysts were found to possess HDM activity and activity maintenance comparable to conventional hydrotreating catalysts available commercially. The vanadium removal selectivity of the mixed metal phosphates was similar to that of the commercial catalyst, but much lower than that observed earlier for oil soluble phosphorous compounds. Since the lack of high vanadium selectivity for the mixed metal phosphates could be due to their transition metal component, they investigated the hydroprocessing of heavy oils over aluminas impregnated with different inorganic phosphorous compounds.

    Aqueous pyrolysis experiments, aimed at mild upgrading of heavy oil, were analyzed using various computer models. The primary focus of the analysis was the pressure history of the closed autoclave reactors obtained during the heating of the autoclave to desired reaction temperatures. The models used included a means of estimating nonideal behavior of primary components with regard to vapor liquid equilibrium. The modeling indicated that to match measured autoclave pressures, which often were well below the vapor pressure of water at a given temperature, it was necessary to incorporate water solubility in the oil phase and an activity model for the water in the oil phase which reduced its fugacity below that of pure water. Analysis also indicated that the mild to moderate upgrading of the oil which occurred in experiments that reached 400{degrees}C or more using a FE(III) 2-ethylhexanoate could be reasonably well characterized by a simple first order rate constant of 1.7xl0{sup 8} exp(-20000/T)s{sup {minus}l}. Both gas production and API gravity increase were characterized by this rate constant. Models were able to match the complete pressure history of the autoclave experiments fairly well with relatively simple equilibria models. However, a consistent lower than measured buildup in pressure at peak temperatures was noted in the model calculations. This phenomena was tentatively attributed to an increase in the amount of water entering the vapor phase caused by a change in its activity in the oil phase.

    Chiyoda's 52 microreactors, bench-scale test units and pilot plants are each used depending on the purpose of the process development for heavy oil upgrading. The microreactors are effective for catalyst screening. Heavier fractions such as asphaltene and sludge materials often disturbed steady state operation. Many unique devices for the test units and improvement of operation procedures make extended operation easy as well as increasing reliability. The computerized data acquisition and data filing systems minimize the work not only for operators but for all research personnel. Currently, about 40 pilot plant units are continuously running while the others are in preparation. Fully automated operation requires only three for data checking at night. In the daytime, seven operators take care of feed supply, product removal and condition changes. For start-up and shut-down, one operator can handle three microreactors, but only one bench-scale unit or pilot plant. Planning is underway for an improved start-up system for the pilot plants using personal computers. This system automatically sets feed rate and raises reactor temperature.

    The U.S. Department of Energy (DOE), Office of Heavy Vehicle Technologies (OHVT) is promoting the use of natural gas as a fuel option in the transportation energy sector through its natural gas vehicle program [1]. The goal of this program is to eliminate the technical and cost barriers associated with displacing imported petroleum. This is achieved by supporting research and development in technologies that reduce manufacturing costs, reduce emissions, and improve vehicle performance and consumer acceptance for natural gas fueled vehicles. In collaboration with Brookhaven National Laboratory, projects are currently being pursued in (1) liquefied natural gas production from unconventional sources, (2) onboard natural gas storage (adsorbent, compressed, and liquefied), (3) natural gas delivery systems for both onboard the vehicle and the refueling station, and (4) regional and enduse strategies. This paper will provide an overview of these projects highlighting their achievements and current status. In addition, it will discuss how the individual technologies developed are being integrated into an overall program strategic plan.

    We show that when the factorized cross section for heavy quarkonium production includes next-to-leading power contributions associated with the production of the heavy quark pair at short distances, it naturally reproduces all high pT results calculated in nonrelativistic QCD (NRQCD) factorization. This extended formalism requires fragmentation functions for heavy quark pairs, as well as for light partons. When these fragmentation functions are themselves calculated using NRQCD, we find that two of the four leading NRQCD production channels, S[1]1 and S[8]0, are dominated by the next-to-leading power contributions for a very wide pT range. The large next-to-leading order corrections of NRQCD are absorbed into the leading order of the first power correction. The impact of this finding on heavy quarkonium production and its polarization is discussed.

    In this study, we show that when the factorized cross section for heavy quarkonium production includes next-to-leading power contributions associated with the production of the heavy quark pair at short distances, it naturally reproduces all high pT results calculated in nonrelativistic QCD (NRQCD) factorization. This extended formalism requires fragmentation functions for heavy quark pairs, as well as for light partons. When these fragmentation functions are themselves calculated using NRQCD, we find that two of the four leading NRQCD production channels, ³S[1]1 and ¹S[8]0, are dominated by the next-to-leading power contributions for a very wide pT range. The large next-to-leading ordermore » corrections of NRQCD are absorbed into the leading order of the first power correction. The impact of this finding on heavy quarkonium production and its polarization is discussed.« less
