Geological evaluation of Gulf Coast salt domes: overall assessment of the Gulf Interior Region  

SciTech Connect (OSTI)

The three major phases in site characterization and selection are regional studies, area studies, and location studies. This report characterizes regional geologic aspects of the Gulf Coast salt dome basins. It includes general information from published sources on the regional geology; the tectonic, domal, and hydrologic stability; and a brief description the salt domes to be investigated. After a screening exercise, eight domes were chosen for further characterization: Keechi, Oakwood, and Palestine Domes in Texas; Vacherie and Rayburn's domes in North Louisiana; and Cypress Creek and Richton domes in Mississippi. A general description of each, maps of the location, property ownership, and surface geology, and a geologic cross section were presented for each dome.

Pelletizing lignite  

DOE Patents [OSTI]

Lignite is formed into high strength pellets having a calorific value of at least 9,500 Btu/lb by blending a sufficient amount of an aqueous base bituminous emulsion with finely-divided raw lignite containing its inherent moisture to form a moistened green mixture containing at least 3 weight % of the bituminous material, based on the total dry weight of the solids, pelletizing the green mixture into discrete green pellets of a predetermined average diameter and drying the green pellets to a predetermined moisture content, preferrably no less than about 5 weight %. Lignite char and mixture of raw lignite and lignite char can be formed into high strength pellets in the same general manner.

Microbial solubilization of lignites  

Science Journals Connector (OSTI)

Biological solubilization and subsequent gasification of lignite samples from three of the largest reserves in this country, which are also characterized by high sulphur contents and low calorific values, were investigated in this project. Several white-rot fungi were screened for their ability to solubilize lignites and Phanerochaete chrysosporium was found to depolymerize Elbistan lignites with 60% efficiency. Acetate served perfectly as the primary carbon source. Whereas, Çan lignites could be depolymerized only after lengthy pre-treatment with 8N HNO3 while Beypazari lignites were completely inert to biological attack. Gasification tests with the solubilize material revealed 21% energy recovery through gaseous methane product.

Final report on decommissioning boreholes and wellsite restoration, Gulf Coast Interior Salt Domes of Mississippi  

SciTech Connect (OSTI)

In 1978, eight salt domes in Texas, Louisiana, and Mississippi were identified for study as potential locations for a nuclear waste repository as part of the National Waste Terminal Storage (NWTS) program. Three domes were selected in Mississippi for ``area characterization`` phase study as follows: Lampton Dome near Columbia, Cypress Creek Dome near New Augusta, and Richton Dome near Richton. The purpose of the studies was to acquire geologic and geohydrologic information from shallow and deep drilling investigations to enable selection of sites suitable for more intensive study. Eleven deep well sites were selected for multiple-well installations to acquire information on the lithologic and hydraulic properties of regional aquifers. In 1986, the Gulf Coast salt domes were eliminated from further consideration for repository development by the selection of three candidate sites in other regions of the country. In 1987, well plugging and restoration of these deferred sites became a closeout activity. The primary objectives of this activity are to plug and abandon all wells and boreholes in accordance with state regulations, restore all drilling sites to as near original condition as feasible, and convey to landowners any wells on their property that they choose to maintain. This report describes the activities undertaken to accomplish these objectives, as outlines in Activity Plan 1--2, ``Activity Plan for Well Plugging and Site Restoration of Test Hole Sites in Mississippi.``

RESOURCE ASSESSMENT OF THE IN-PLACE AND POTENTIALLY RECOVERABLE DEEP NATURAL GAS RESOURCE OF THE ONSHORE INTERIOR SALT BASINS, NORTH CENTRAL AND NORTHEASTERN GULF OF MEXICO  

SciTech Connect (OSTI)

The University of Alabama and Louisiana State University have undertaken a cooperative 3-year, advanced subsurface methodology resource assessment project, involving petroleum system identification, characterization and modeling, to facilitate exploration for a potential major source of natural gas that is deeply buried (below 15,000 feet) in the onshore interior salt basins of the North Central and Northeastern Gulf of Mexico areas. The project is designed to assist in the formulation of advanced exploration strategies for funding and maximizing the recovery from deep natural gas domestic resources at reduced costs and risks and with minimum impact. The results of the project should serve to enhance exploration efforts by domestic companies in their search for new petroleum resources, especially those deeply buried (below 15,000 feet) natural gas resources, and should support the domestic industry's endeavor to provide an increase in reliable and affordable supplies of fossil fuels. The principal research effort for Year 1 of the project is data compilation and petroleum system identification. The research focus for the first nine (9) months of Year 1 is on data compilation and for the remainder of the year the emphasis is on petroleum system identification. The objectives of the study are: to perform resource assessment of the in-place deep (>15,000 ft) natural gas resource of the onshore interior salt basins of the North Central and Northeastern Gulf of Mexico areas through petroleum system identification, characterization and modeling and to use the petroleum system based resource assessment to estimate the volume of the in-place deep gas resource that is potentially recoverable and to identify those areas in the interior salt basins with high potential to recover commercial quantities of the deep gas resource. The project objectives will be achieved through a 3-year effort. First, emphasis is on petroleum system identification and characterization in the North Louisiana Salt Basin, the Mississippi Interior Salt Basin, the Manila Sub-basin and the Conecuh Sub-basin of Louisiana, Mississippi, Alabama and Florida panhandle. This task includes identification of the petroleum systems in these basins and the characterization of the overburden, source, reservoir and seal rocks of the petroleum systems and of the associated petroleum traps. Second, emphasis is on petroleum system modeling. This task includes the assessment of the timing of deep (>15,000 ft) gas generation, expulsion, migration, entrapment and alteration (thermal cracking of oil to gas). Third, emphasis is on resource assessment. This task includes the volumetric calculation of the total in-place hydrocarbon resource generated, the determination of the volume of the generated hydrocarbon resource that is classified as deep (>15,000 ft) gas, the estimation of the volume of deep gas that was expelled, migrated and entrapped, and the calculation of the potential volume of gas in deeply buried (>15,000 ft) reservoirs resulting from the process of thermal cracking of liquid hydrocarbons and their transformation to gas in the reservoir. Fourth, emphasis is on identifying those areas in the onshore interior salt basins with high potential to recover commercial quantities of the deep gas resource.

Final report on decommissioning of wells, boreholes, and tiltmeter sites, Gulf Coast Interior Salt Domes of Louisiana  

SciTech Connect (OSTI)

In the late 1970s, test holes were drilled in northern Louisiana in the vicinity of Vacherie and Rayburn`s Salt Domes as part of the Department of Energy`s (DOE) National Waste Terminal Storage (NWTS) (rename the Civilian Radioactive Waste Management (CRWM)) program. The purpose of the program was to evaluate the suitability of salt domes for long term storage or disposal of high-level nuclear waste. The Institute for Environmental Studies at Louisiana State University (IES/LSU) and Law Engineering Testing Company (LETCo) of Marietta, Georgia performed the initial field studies. In 1982, DOE awarded a contract to the Earth Technology Corporation (TETC) of Long Beach, California to continue the Gulf Coast Salt Dome studies. In 1986, DOE deferred salt domes from further consideration as repository sites. This report describes test well plugging and site abandonment activities performed by SWEC in accordance with Activity Plan (AP) 1--3, Well Plugging and Site Restoration of Work Sites in Louisiana. The objective of the work outlined in this AP was to return test sites to as near original condition as possible by plugging boreholes, removing equipment, regrading, and seeding. Appendices to this report contain forms required by State of Louisiana, used by SWEC to document decommissioning activities, and pertinent documentation related to lease/access agreements.

Lignite Fuel Enhancement  

SciTech Connect (OSTI)

This 11th quarterly Technical Progress Report for the Lignite Fuel Enhancement Project summarizes activities from January 1st through March 31st of 2007. It summarizes the completion of the Prototype testing activity and initial full-scale dryer design, Budget Period 2 activity during that time period. The Design Team completed process design and layouts of air, water, and coal systems. Heyl-Patterson completed dryer drawings and has sent RFPs to several fabricators for build and assembly. Several meetings were held with Barr engineers to finalize arrangement of the drying, air jig, and coal handling systems. Honeywell held meetings do discuss the control system logic and hardware location. By the end of March we had processed nearly 300,000 tons of lignite through the dryer. Outage preparation maintenance activities on a coal transfer hopper restricted operation of the dryer in February and March. The Outage began March 17th. We will not dry coal again until early May when the Outage on Unit No.2 completes. The Budget Period 1 (Phase 1) final report was submitted this quarter. Comments were received from NETL and are being reviewed. The Phase 2 Project Management Plan was submitted to NETL in January 2007. This deliverable also included the Financing Plan. An application for R&D 100 award was submitted in February. The project received an award from the Minnesota Professional Engineering Society's Seven Wonders of Engineering Award and Minnesota ACEC Grand Award in January. To further summarize, the focus this quarter has been on finalizing commercial design and the layout of four dryers behind each Unit. The modification to the coal handling facilities at Coal Creek and incorporation of air jigs to further beneficiate the segregated material the dryers will reject 20 to 30 % of the mercury and sulfur is segregated however this modification will recover the carbon in that stream.

Basin Analysis and Petroleum System Characterization and Modeling, Interior Salt Basins, Central and Eastern Gulf of Mexico  

SciTech Connect (OSTI)

The principal research effort for Phase 1 (Concept Development) of the project has been data compilation; determination of the tectonic, depositional, burial, and thermal maturation histories of the North Louisiana Salt Basin; basin modeling (geohistory, thermal maturation, hydrocarbon expulsion); petroleum system identification; comparative basin evaluation; and resource assessment. Existing information on the North Louisiana Salt Basin has been evaluated, an electronic database has been developed, and regional cross sections have been prepared. Structure, isopach and formation lithology maps have been constructed, and burial history, thermal maturation history, and hydrocarbon expulsion profiles have been prepared. Seismic data, cross sections, subsurface maps and burial history, thermal maturation history, and hydrocarbon expulsion profiles have been used in evaluating the tectonic, depositional, burial and thermal maturation histories of the basin. Oil and gas reservoirs have been found to be associated with salt-supported anticlinal and domal features (salt pillows, turtle structures and piercement domes); with normal faulting associated with the northern basin margin and listric down-to-the-basin faults (state-line fault complex) and faulted salt features; and with combination structural and stratigraphic features (Sabine and Monroe Uplifts) and monoclinal features with lithologic variations. Petroleum reservoirs include Upper Jurassic and Cretaceous fluvial-deltaic sandstone facies; shoreline, marine bar and shallow shelf sandstone facies; and carbonate shoal, shelf and reef facies. Cretaceous unconformities significantly contribute to the hydrocarbon trapping mechanism capacity in the North Louisiana Salt Basin. The chief petroleum source rock in this basin is Upper Jurassic Smackover lime mudstone beds. The generation of hydrocarbons from Smackover lime mudstone was initiated during the Early Cretaceous and continued into the Tertiary. Hydrocarbon expulsion commenced during the Early Cretaceous and continued into the Tertiary with peak expulsion occurring during the Early to Late Cretaceous. The geohistory of the North Louisiana Salt Basin is comparable to the Mississippi Interior Salt Basin with the major difference being the elevated heat flow the strata in the North Louisiana Salt Basin experienced in the Cretaceous due primarily to reactivation of upward movement, igneous activity, and erosion associated with the Monroe and Sabine Uplifts. Potential undiscovered reservoirs in the North Louisiana Salt Basin are Triassic Eagle Mills sandstone and deeply buried Upper Jurassic sandstone and limestone. Potential underdeveloped reservoirs include Lower Cretaceous sandstone and limestone and Upper Cretaceous sandstone.

COFIRING BIOMASS WITH LIGNITE COAL  

SciTech Connect (OSTI)

The University of North Dakota Energy & Environmental Research Center, in support of the U.S. Department of Energy's (DOE) biomass cofiring program, completed a Phase 1 feasibility study investigating aspects of cofiring lignite coal with biomass relative to utility-scale systems, specifically focusing on a small stoker system located at the North Dakota State Penitentiary (NDSP) in Bismarck, North Dakota. A complete biomass resource assessment was completed, the stoker was redesigned to accept biomass, fuel characterization and fireside modeling tests were performed, and an engineering economic analysis was completed. In general, municipal wood residue was found to be the most viable fuel choice, and the modeling showed that fireside problems would be minimal. Experimental ash deposits from firing 50% biomass were found to be weaker and more friable compared to baseline lignite coal. Experimental sulfur and NO{sub x} emissions were reduced by up to 46%. The direct costs savings to NDSP, from cogeneration and fuel saving, results in a 15- to 20-year payback on a $1,680,000 investment, while the total benefits to the greater community would include reduced landfill burden, alleviation of fees for disposal by local businesses, and additional jobs created both for the stoker system as well as from the savings spread throughout the community.

Mitsubishi FGD plants for lignite fired boilers  

SciTech Connect (OSTI)

In order to respond to the increasing electric energy demand for sustaining economic growth, construction of coal-fired thermal power plants worldwide is indispensable. As a countermeasure for environmental pollution which otherwise may reach a serious proportion from the operation of these plants, construction of flue gas desulfurization (FGD) plants is being promoted. Among these power stations where lignite fuel is burnt, the FGD plants concerned have to be designed to cope with high gas volume and SO{sub x} concentration as well as violent fluctuations in their values caused by such features of lignite as high sulfur content, low calorific volume, and unstable properties. Mitsubishi Heavy Industries (MHI) has received construction awards for a total of seven (7) FGD plants for lignite-fired boilers in succession starting from that for CEZ as, Czech Republic followed by those for EGAT, Thailand in 1993. All these plants are presently operating satisfactorily since successful completion of their performance tests in 1996. Further, a construction award of three (3) more FGD plants for lignite-fired boilers was received from ENDESA (Spain) in 1995 which are now being outfitted and scheduled to start commercial operation in 1998. In this paper, the authors discuss the outline design of FGD plants for lignite-fired boilers based on experience of FGD plants constructed since 1970 for heavy oil--as well as black coal-fired boilers, together with items confirmed from the operation and design guideline hereafter.

Correlation of lignites in the midway and Wilcox groups of southern Alabama and eastern Mississippi  

SciTech Connect (OSTI)

The Gulf Coast Paleogene section represents one of the world's most continuous records of cyclic nonmarine through marine sedimentation. Microfossil research has demonstrated the completeness of downdip marine sections; however, the continuity of updip, nonmarine, and marginal marine sections remains relatively uncertain. Lignites occur throughout the Gulf Coast low Paleogene, but to date have not been adequately characterized with the detail necessary for high-resolution correlation. Lignite characteristics, stratigraphic position within Paleogene depositional cycles, and their mode of origin can be used in correlating nonmarine deposits (highstand system tract) to downdip marine deposits (transgressive system tract). Samples were collected for east-central Mississippi and west-central Alabama and analyzed. Principle constituents, comprising over 50%, are inaperturate forms in Midway Group samples and tricolporate forms in Wilcox Group samples. Secondary components, 10-20%, of triporate and monolete/trilete forms occur in both groups. Triporate forms are approximately 25% more abundant in the Wilcox Group samples, whereas monolete/trilete forms remain relatively constant in both groups. Minor components ([le]5%) of bivesticulate, tricolpate, polycolpate, polyporate, and polycolporate forms are present, but show distinct percentage variations between each group. Inaperature forms are present only in the Midway Group and monoporate forms exist only in the Wilcox Group.

APP, a new binder for briquetting lignites  

Science Journals Connector (OSTI)

Turkey has considerable lignite reserves that are mainly used as domestic fuel without processing. The lignite weathers and degrades easily and much is lost as dust before it reaches the consumer; furthermore, in combustion fine particles can cause air pollution. Since briquetting can eliminate many of these existing problems, it is of special importance. Binderless briquetting is always preferred when possible, since it is less complicated and less expensive, but Turkish lignites usually require a binder to obtain reasonable briquettes and various binders can be used for this purpose. In this work, atactic polypropylene (APP), a by-product of the polypropylene (PP) plant of Petkim Petrochemicals A.S. and emulsions of partially oxidized APP prepared by the research centre of the company, were used as binders, with different types of briquetting techniques. Studies on a laboratory scale were carried out to determine optimum parameters of briquetting; binder content, water content, pressure and temperature of heat treatment. Shatter and water resistance tests were carried out on briquettes obtained under different conditions. APP appears to have many advantages, and none of the disadvantages of other commercial binders such as tar, bitumen, molasses, sulphide liquor and clay. Furthermore, unlike other plastics that cause difficulties in briquetting and have high manufacturing costs, APP, particularly in emulsion, can easily be used as a binder and is relatively cheap. However, a production unit would be required to prepare the relevant modified APP emulsion for its extended usage.

Geotechnical characterization of lignite-bearing horizons in the Afsin–Elbistan lignite basin, SE Turkey  

Science Journals Connector (OSTI)

The Afsin–Elbistan lignite deposit, with its 3.4 billion metric tons of reserves, is the biggest lignite basin and one of the most important resources for electrical energy production in Turkey. Kislakoy mining field was selected as the first opencast mine to feed four power station blocks of 300 MW each. Slope instability has been a continuing problem in the Kislakoy opencast mine. Particularly complex failures along a noncircular failure surface appearing at the final slope stage and covering large areas in the mine increase the importance of slope stability. This study outlines the geotechnical characteristics of the lignite-bearing horizons and describes the causes and mechanisms of slope instabilities, which threaten the safety of the mine. Quantitative X-ray diffraction (XRD) analyses were carried out using an interactive data processing system (SIROQUANT™) based on Rietveld interpretation methods. Parametric slope stability analysis and backanalysis were carried out for the failure that occurred at the northwestern final slope stage of the mine. The Spencer–Wright limiting state equilibrium method was used in order to determine with confidence the most representative values of regional shear strength parameters, to explain the failure mechanism, and to assess the conditions at the time of failure. In the analysis, phreatic and piezometric surfaces were considered. Site observations and numerous backanalyses of the slope failure reveal that a compound slide occurred where gyttja (contact zone) layers rest directly on the lignite. Gyttja (contact zone) contains the weakest material within the system. The analysis showed that the main cause of the northwestern slope instability was the presence of the groundwater flow within a Quaternary aquifer (through buried valleys), reducing the effective shear strength of the slope materials. It is also noted from backanalysis that the gyttja (contact zone) layer presents a shear strength at, or approaching, the residual value at the time of failure.

The washability of lignites for clay removal  

SciTech Connect (OSTI)

In the washability research of the Seyitomer Lignites (Kutahya-Turkey), with lower calorific value (1,863 kcal/kg) and high ash content (51.91%), by heavy medium separation, it was found out that middling clay in the coal had an effect to change the medium density. To prevent this problem, a trommel sieve with 18 and 5 mm aperture diameter was designed, and the clay in the coal was tried to be removed using it before the coal was released to heavy medium. Following that, the obtained coal in -100 + 18 mm and -18 + 5 mm fractions was subjected to sink and float test having 1.4 gcm{sup -3} and 1.7 gcm{sup -3} medium densities (-5 mm fraction will be evaluated in a separate work). Depending on the raw coal, with the floating of -100 + 18 mm and -18 + 5 mm size fraction in 1.4 gcm{sup -3} medium density, clean coal with 60.10% combustible matter recovery, 19.12% ash, and 3,150 kcal/kg was obtained. Also floating of the samples sinking in 1.4 gcm{sup -3} in the medium density (1.7 gcm{sup -3}), middling with 18.70% combustible matter recovery, 41.93% ash, 2,150 kcal/kg, and tailing having 78.31% ash were obtained.

Lignite resources of Turkey: Geology, reserves, and exploration history  

Science Journals Connector (OSTI)

Abstract This article aims to emphasize the importance of lignite, which is the mostly used domestic energy source in the Turkish energy mix, by briefly overviewing its geology, reserves, and exploration. Lignites are distributed in mostly continental sedimentary basins of Tertiary age all over the country. The lignite-bearing basins display the characteristics of different geological settings, of which grabens and half-grabens are the most common ones especially in western Anatolia. The geological and chemical characteristics of Turkish lignites do not only create some important problems during mining and coal preparation but also make them unfavorable for consumption. However, since they are the most valuable energy resource of the country they should benefit the economy in the most efficient and environmentally friendly way. Moreover, two most important conclusions of this study are as follows: firstly, reserve estimation practices in the country should definitely be revised to provide a more realistic evaluation of the country's lignite potential for developing medium- and long-term energy strategies and policies for decision- and policy-makers. Secondly, exploration and development activities should be coordinated by a single institution, most likely a government institution, as has been the case for some 50 years.

Sedimentary regimes of upper Midway and lower Wilcox lignite in Alabama  

SciTech Connect (OSTI)

Paleoenvironments favorable for lignite deposition existed in sedimentary regimes of the Naheola Formation (upper Midway Group) and in Midway-Wilcox transition sediments apparently assignable to the Nanafalia Formation (Wilcox Group). In addition, lignite horizons are recognized in the Tuscahoma Sand (Wilcox Group). Lignite of potential economic significance occurs within the Naheola Formation west of Butler County and within the Nanafalia Formation east of Butler County. Lignite horizons in the Naheola Formation west of Butler County probably are not stratigraphically or time equivalent to lignite horizons east of Butler County. Depositional environments of the Naheola west of Butler County were favorable for development of lignite deposits with extensive lateral continuity, whereas lignite depositional environments east of Butler County apparently favored variability in thickness and lateral continuity. Estuarine and back-barrier coastal marsh environments are suggested for the lignite. Carbonaceous silt and clay in varying proportions are commonly associated with lignite in the Naheola Formation. Lithologic associations of lignite related to the Nanafalia Formation include quartzarenite, carbonaceous silt and clay, oyster beds, and limestone of the Clayton Formation (Midway Group).

Lignite industry in Greece within a world context: Mining, energy supply and environment  

Science Journals Connector (OSTI)

Today coal covers 38% of global production and roughly 30% of the EU-25 power output. In 2005 domestic lignite with a share of 60.5% in power generation and accounting about 30% of primary energy consumption is currently the most important indigenous fuel of Greece. Greece, mining 70 Mt annually, is the second lignite producer in the EU and fourth in the world. Approximately 97% of the lignite used to supply the existing lignite-fired power plants of Greece is mined by Public Power Corporation S.A. (PPC). Lignite as the base load fuel gives a competitive strength in PPC's and Greece's fuel mix. Due to lignite consumer prices in Greece are significantly below those in other comparable markets in EU-15. Extraction of lignite has a very long tradition. Significant achievements and large experience which has been gained during many years of mining operations place Greek lignite-mining industry in the leading position in Europe. The paper presents current state of Greek lignite industry, including operating mines, volume of production and other important production indicators as well as improvements in labor productivity and good results in industrial safety. The future of coal and specifically of Greek lignite will be crucially determined by environmentally compatible, i.e. low-CO2 generation of electricity. Investment in modernization and renewal of the power plant fleet are the key to securing electricity supply and progress in preventing climate change.

Roles of inherent mineral matters for lignite water slurry electrolysis in H2SO4 system  

Science Journals Connector (OSTI)

Abstract To understand roles of inherent mineral matters in lignite water slurry (LWS) electrolysis, lignite and demineralized lignite electrolyses were carried out in H2SO4 system. The results showed that cell voltage for LWS electrolysis was lower than that for demineralized lignite water slurry (DLWS) under constant current condition. Some inherent mineral matters changed into the corresponding metal ions which entered into electrolyte, and thus improved the electrolysis oxidation reactions for coal organic structure. Meanwhile, the relative amount of O-containing functional groups in demineralized lignite increased with electrolysis time, improving its pyrolysis reactivity. However, the pyrolysis reactivity of raw lignite decreased due to the removal of the inherent mineral matters from electrolysis.

Estimation of lignite reserve in the Kalburcayiri field, Kangal basin, Sivas, Turkey  

Science Journals Connector (OSTI)

This paper addresses a case study on global estimation of lignite reserve in the Kalburcayiri field from the Sivas–Kangal basin, which is one of the most productive lignite basins in eastern Anatolia, Turkey. The two lignite seams, which were developed in a fresh-water lacustrine depositional environment during the Pliocene time, are currently being exploited in the Kalburcayiri open-cast mine for feed coal to a power plant with 300-MW capacity. Tonnage, thickness and quality parameters (ash yield, total sulphur content, and calorific value) of the lignite are variables considered in this study. The global estimates of these variables together with 95% confidence limits are obtained using the approximation principle of global estimation. A random stratified grid is fitted to available boreholes; the variograms for thickness and lignite quality parameters are estimated and modeled. The models are used in calculating estimation error variances that will later be used in constructing 95% confidence intervals for the true values.

Present situation and prospects for lignite in the Polish power-generation industry  

Science Journals Connector (OSTI)

In Poland, lignite is mined in open pits and four deep mines, producing totally about 60–65 million tons a year. Extracted lignite constitutes a fuel for power plants with a total installed capacity of 8833 MW, which generate some 35% of electric energy nationally. This energy is cheaper compared with that from other sources. Poland, with its huge deposits of lignite, is placed in a privileged position, for apart from at present mined deposits, which constitute only about 15% of workable reserves, some abundant areas exist, where mining working can be started. At present, the mined deposits allow us to maintain a current yearly output for the forthcoming 15 years, whereas through the subsequent 30 years, it will decline. In order to maintain supplies of lignite, which is a significant fuel in Poland, it is necessary to fully utilize deposits in the existing areas, and develop new zones where lignite occurs.

The unstable Gulf  

SciTech Connect (OSTI)

This book is an analysis of the international political environment for business in the Gulf region. To secure the flow of oil supplies to the West, the U.S. relies on stable relations with the key Gulf states: Saudi Arabia, Kuwait, Oman, the United Arab Emirates, Bahrain, and Qatar. The region's dynamic balance of power, however, is inherently destabilizing, which threatens the investment climate and the billions of dollars of international commerce with the Gulf states expected in the next decade. Dr. Martin analyzes the effects of the religious, ethnic, and ideological differences in the Persian Gulf on superpower competition and U.S. energy policy.

Task 50 - deposition of lignites in the Fort Union Group and related strata of the northern Great Plains  

SciTech Connect (OSTI)

Late Cretaceous, Paleocene, and early Eocene geologic and paleontologic studies were undertaken in western North Dakota, eastern and south-central Montana, and northwestern and northeastern Wyoming. These study areas comprise the Williston, Bighorn, and Powder River Basins, all of which contain significant lignite resources. Research was undertaken in these basins because they have the best geologic sections and fossil record for the development of a chronostratigraphic (time-rock) framework for the correlation of lignite beds and other economic resources. A thorough understanding of the precise geologic age of the deposition of sediments permits a powerful means of interpreting the record of geologic events across the northern Great Plains. Such an understanding allows for rigorous interpretation of paleoenviromnents and estimates of resource potential and quality in this area of economically significant deposits. This work is part of ongoing research to document change in the composition of molluscan fossil faunas to provide a paleoenvironmentally sensitive independent means of interpreting time intervals of brief duration during the Late Cretaceous, Paleocene, and Eocene. This study focuses on the record of mollusks and, to a lesser extent, mammals in the (1) Hell Creek-Tullock Formations, which include the Cretaceous-Paleocene boundary, in the western portion of the Williston Basin, Montana; (2) uppermost Cretaceous, Paleocene, and lowermost Eocene strata in western North Dakota, which -includes the last interior seaway in North Dakota; (3) upper Paleocene and lowermost Eocene of the northern portion of the Bighorn Basin of south-central Montana and northwestern Wyoming; and (4) Powder River Basin of northeastern Wyoming and southeastern Montana. The geologic record provides different physical and paleontological information to aid in interpreting the geologic record through the study interval.

Coal geology of the U.S. Gulf Coastal region  

SciTech Connect (OSTI)

The US Geological Survey (USGS) is conducting a comprehensive assessment of the major coal regions of the country. In this program, known as the National Coal Resource Assessment, the quantity and quality of coals that are expected to be mined during the next 30 years will be characterized. For the Gulf Coast region, the evaluation will include reviews of the stratigraphic setting, resource potential, and the quality of the lignites in four coal-producing areas. These areas are: the Sabine Uplift (including parts of Texas and Louisiana), Northeast Texas, Central Texas, and South Texas. The results of these efforts will be a series of digital Geographic Information System (GIS) maps, text, and tables that will be published in a CD-ROM format. These products, along with a national summary CD-ROM, are expected to be completed in 1999. This paper is to present a review of Gulf Coast coal geology and to outline the USGS assessment efforts for the Gulf Coast region. Most coal in the Gulf Coast area is produced from the Paleocene Wilcox Group, and minor amounts of coal are produced from the Ecocene Jackson and Claiborne Groups. Initial results indicate that for coals being mined in the Sabine Uplift, Northeast, and Central Texas areas mean moisture values are about 34%, mean ash yields range from 12 to 15%, and mean calorific values range from about 5,800 to 6,900 Btu/lb (all data are on an as-received basis). Detailed bed and zone analysis in all areas indicate that resource figures will be greater than previous estimates that have usually combined multiple coal horizons to estimate cumulative coal thicknesses for a formation. Ongoing research in the Sabine Uplift and Northeast study areas suggests that coal zones in both the upper and lower Wilcox may be more laterally extensive than previous studies indicate.

Reclamation planning and operation at the Mae Moh Lignite Mine, Thailand  

SciTech Connect (OSTI)

The Mae Moh Mine is a large open cut lignite mine situated in Northern Thailand. The mine produces lignite for coal fired power stations located adjacent to the mine. Current mine production is approximately 9 Mtpa providing lignite to eight power stations with a total output of 1,125 MW. The power development plan for Mae Moh provides for 19 power stations by the year 1999 which will require lignite production to be increased to 30.5 Mtpa and overburden will be mined at a rate approaching 300 Mtpa. Environmental management and reclamation planning at Mae Moh are major issues due to water quality impact and land use conflicts. This paper presents the key elements of the reclamation master plan and works strategy for progressive reclamation and water pollution control.

JV Task - 129 Advanced Conversion Test - Bulgarian Lignite  

SciTech Connect (OSTI)

The objectives of this Energy & Environmental Research Center (EERC) project were to evaluate Bulgarian lignite performance under both fluid-bed combustion and gasification conditions and provide a recommendation as to which technology would be the most technically feasible for the particular feedstock and also identify any potential operating issues (such as bed agglomeration, etc.) that may limit the applicability of a potential coal conversion technology. Gasification tests were run at the EERC in the 100-400-kg/hr transport reactor development unit (TRDU) on a 50-tonne sample of lignite supplied by the Bulgarian Lignite Power Project. The quality of the test sample was inferior to any coal previously tested in this unit, containing 50% ash at 26.7% moisture and having a higher heating value of 5043 kJ/kg after partial drying in preparation for testing. The tentative conclusion reached on the basis of tests in the TRDU is that oxygen-blown gasification of this high-ash Bulgarian lignite sample using the Kellogg, Brown, and Root (KBR) transport gasifier technology would not provide a syngas suitable for directly firing a gas turbine. After correcting for test conditions specific to the pilot-scale TRDU, including an unavoidably high heat loss and nitrogen dilution by transport air, the best-case heating value for oxygen-blown operation was estimated to be 3316 kJ/m{sup 3} for a commercial KRB transport gasifier. This heating value is about 80% of the minimum required for firing a gas turbine. Removing 50% of the carbon dioxide from the syngas would increase the heating value to 4583 kJ/m{sup 3}, i.e., to about 110% of the minimum requirement, and 95% removal would provide a heating value of 7080 kJ/m{sup 3}. Supplemental firing of natural gas would also allow the integrated gasification combined cycle (IGCC) technology to be utilized without having to remove CO{sub 2}. If removal of all nitrogen from the input gas streams such as the coal transport air were achieved, a heating value very close to that needed to fire a gas turbine would be achieved; however, some operational issues associated with utilizing recycled syngas or carbon dioxide as the transport gas would also have to be resolved. Use of a coal with a quality similar to the core samples provided earlier in the test program would also improve the gasifier performance. Low cold-gas efficiencies on the order of 20% calculated for oxygen-blown tests resulted in part from specific difficulties experienced in trying to operate the pilot-scale TRDU on this very high-ash lignite. These low levels of efficiency are not believed to be representative of what could be achieved in a commercial KRB transport gasifier. Combustion tests were also performed in the EERC's circulating fluidized-bed combustor (CFBC) to evaluate this alternative technology for use of this fuel. It was demonstrated that this fuel does have sufficient heating value to sustain combustion, even without coal drying; however, it will be challenging to economically extract sufficient energy for the generation of steam for electrical generation. The boiler efficiency for the dried coal was 73.5% at 85% sulfur capture (21.4% moisture) compared to 55.3% at 85% sulfur capture (40% moisture). Improved boiler efficiencies for this coal will be possible operating a system more specifically designed to maximize heat extraction from the ash streams for this high-ash fuel. Drying of the coal to approximately 25% moisture probably would be recommended for either power system. Fuel moisture also has a large impact on fuel feedability. Pressurized gasifiers generally like drier fuels than systems operating at ambient pressures. The commercially recommended feedstock moisture for a pressurized transport reactor gasifier is 25% moisture. Maximum moisture content for a CFB system could be approximately 40% moisture as has been demonstrated on the Alstom CFB operating on Mississippi lignite. A preliminary economic evaluation for CO{sub 2} was performed on the alternatives of (1) precombustion separation of CO{sub 2} in

Lignite-fired thermal power plants and SO2 pollution in Turkey  

Science Journals Connector (OSTI)

About 80% of the electric energy production in Turkey is provided by thermal power plants which use fossil fuels. Lignite, the most abundant domestic energy source, is consumed in most of these plants. Turkey has approximately 0.85% of the world's lignite reserves; however, the Turkish lignites have low calorific value and contain relatively higher amounts of ash, moisture, and sulfur. Nearly 80% of the lignite mined in Turkey is consumed in the thermal power plants since it is not appropriate for use in other types of industry and heating. In Turkey, 13 large-scale lignite-fired thermal power plants are responsible for a considerable amount of air pollution. Therefore, it is crucial to decide on the optimal place and technology for the future thermal power plants, and to equip the currently operating plants with newer technologies that will reduce amount of contaminants released into the air. In this study, the effects of the lignite-fired thermal power plants which have an important place in the energy politics in Turkey on the air pollution are investigated. We focused on SO2 pollution and the regions in which the SO2 emissions were concentrated and diffused. The pollutant diffusion areas were projected and mapped based on parameters such as wind data, isotherm curves, population density, and topographic features by using Geographical Information System (GIS) software, ArcView. The contribution of the thermal power plants to SO2 pollution was also examined.

The Af?in–Elbistan lignite basin, containing 47% of the overall lignite reserve in Turkey, lies in the Af?in and Elbistan districts as a part of Kahramanmara?. The new Çöllolar opencast mine is in the Afsin–Elbistan lignite basin, and this mine will be the second mining activity in the basin after the active K??laköy opencast mine. The new mine will meet the coal consumption of the Elbistan B power plant. Input parameters for slope stability analysis are essential, and so they must be determined accurately and precisely. Field investigations, laboratory testing and back analyses are vital instruments for the input parameters. This study presents the results of slope stability analysis via finite difference code and a limit equilibrium software for the soil slopes of the Elbistan–Çöllolar lignite mine. The basic input parameters, cohesion and friction angle, were determined in the soil mechanics laboratory. By back analyses of a large scale slope failure, mobilized friction angles for a critical weak clay layer under the lignite seam were determined accurately by using the 2D limit equilibrium method and 3D finite difference models. Results of the friction angles were compared in order to check the effectiveness of commonly used 2D approaches in handling the slope problems. Differences in the results of the mobilized friction angles for the weak clay layer were more than 30%. The 3D models indicated that the mobilized friction angle during the major slope failure was substantially lower than the friction angle generated by the 2D limit equilibrium method.

Comparative radiocarbon dating of lignite, pottery, and charcoal samples from Babeldaob Island, Republic of Palau  

SciTech Connect (OSTI)

It is difficult to construct archaeological chronologies for Babeldaob, the main island of Palau (western Micronesia), because the saprolitic clays of the dominant terraced-hill sites and associated ceramic sherds often contain old carbon that originated in lignites. This has implications, as well, for chronologies of sedimentary sequences. Comparative analysis of the dating problem using lignite, pottery, and charcoal samples indicates that, in fact, there are both old and young sources of potential contamination. It is concluded that radiocarbon samples from Babeldaob need to be tested for appropriate carbon content rather than relying solely upon material identification.

Cofiring lignite with hazelnut shell and cotton residue in a pilot-scale fluidized bed combustor  

SciTech Connect (OSTI)

In this study, cofiring of high ash and sulfur content lignite with hazelnut shell and cotton residue was investigated in 0.3 MWt METU Atmospheric Bubbling Fluidized Bed Combustion (ABFBC) Test Rig in terms of combustion and emission performance of different fuel blends. The results reveal that cofiring of hazelnut shell and cotton residue with lignite increases the combustion efficiency and freeboard temperatures compared to those of lignite firing with limestone addition only. CO{sub 2} emission is not found sensitive to increase in hazelnut shell and cotton residue share in fuel blend. Cofiring lowers SO{sub 2} emissions considerably. Cofiring of hazelnut shell reduces NO and N{sub 2}O emissions; on the contrary, cofiring cotton residue results in higher NO and N{sub 2}O emissions. Higher share of biomass in the fuel blend results in coarser cyclone ash particles. Hazelnut shell and cotton residue can be cofired with high ash and sulfur-containing lignite without operational problems. 32 refs., 12 figs., 11 tabs.

Selective mining of multiple-layer lignite deposits. A fuzzy approach  

Science Journals Connector (OSTI)

In this paper the development and the application of a fuzzy expert system for the evaluation of the exploitable reserves of multiple-layer lignite deposits, mined by continuous surface methods, is presented. The exploitable reserves are determined decisively by the structure of these deposits, as well as by the limitations of the used mining systems. In practice, thin layers of lignite and interbedded waste layers are grouped under specified assumptions regarding thickness and ash content, to form the exploitable blocks. Moreover, the decision for excavating such a block is made under subjective constraints of different importance, or by using uncertain data. Advances in fuzzy inference systems (FIS) have provided a new approach to the evaluation of multiple-layer lignite deposits. FIS have the ability to handle imprecise, incomplete or linguistically ambiguous information and incorporate them into decision-making processes. In the developed FIS (Mamdani type) new linguistic variables, related to working conditions, operators’ experience and production were involved. The FIS was used for the estimation of the exploitable reserves of the Southern Field lignite deposit, located in the area of Ptolemais (Greece).

Evaluation of the long-term environmental performance of Greek lignite-fired power stations  

Science Journals Connector (OSTI)

Abstract At national, regional and global level, there is no doubt that the electric generation from fossil fuel-fired power plants is one of the greatest causes of air pollution and climate change. However, fossil fuels contribute more than 70% in the planet electricity generation during the last 30 years. In Greece, lignite is the only proved significant indigenous fossil fuel source, currently representing about 50% of the national electricity generation (a situation which is not expected to change dramatically in the near future). As a result, owed to the use of local lignite reserves (poor quality lignite), the Greek Lignite Thermal Power Stations (LTPSs) are responsible for the production of significant airborne emissions and particle releases (e.g. CO2, SO2, NOX, PM). At the same time, Greece, on top of the Kyoto Protocol, has accepted specific obligations and incorporated into its national legislation several air quality Directives concerning the reduction of various harmful gases and particle releases attributed to fossil fuel combustion. Thus, wide scrutiny of concentration time series of all these airborne emissions constitutes an important indicator of the current technology used, considering at the same time that any violation noted should be the object of serious national concern. Under this argument, the current work presents and evaluates the long-term environmental performance of the Greek lignite-based electricity generation system as far as CO2, NOX, SO2 and PM are concerned up to the year 2011. According to the results obtained, one may rank the operating \\{LTPSs\\} according to their environmental performance giving to the Greek society the necessary tools to determine their utilisation factor on top of the techno-economic criteria used up to now.

Evaluation of an on-line ash analysis system for low-grade and inhomogeneous Greek lignite  

SciTech Connect (OSTI)

The possibility of using commercial on-line analysis systems for monitoring the ash content of low-grade lignites was investigated by carrying out numerous bench- and pilot-scale trials in the mines of Public Power Corporation SA, Greece. Pilot-scale trials were based on a dual-energy {gamma}-ray transmission analyzer, which was installed on the conveyor belt that transports lignite from the pit to the bunker of Kardia mine, Ptolemais. According to the obtained results, the accuracy of the on-line measurements was not adequate and did not allow lignite quality monitoring in real time. The deterioration of the on-line measurements' accuracy, compared to previous applications in other mining sites, was related to the intense variation of the lignite ash content and ash composition, which distorted the calibration of the analyzer. The latter is based on certain assumptions regarding the average atomic number of the organic and mineral matter contained in the lignite. Further experimental work is needed to investigate solutions for successful implementation of this method to low-grade lignites that exhibit large variation in ash content and composition. 17 refs., 15 figs., 7 tabs.

Mercury control for Plants firing Mercury control for Plants firing texas lignite and equiPPed with esP-wet fgd Background The 2005 Clean Air Mercury Rule will require significant reductions in mercury emissions from coal-fired power plants. One promising mercury control technology involves the use of sorbents such as powdered activated carbon. Full-scale sorbent injection tests conducted for various combinations of fuel and plant air pollution control devices have provided a good understanding of variables that affect sorbent performance. However, many uncertainties exist regarding long-term performance, and data gaps remain for specific plant configurations. Sorbent injection has not been demonstrated at full-scale for plants firing Texas lignite coal, which are responsible for about 10 percent of annual U.S. power plant

Production of a nitrogeneous humic fertilizer by the oxidation-ammoniation of lignite  

SciTech Connect (OSTI)

Two lignite samples were oxidised with HNO/sub 3/ (20% wt) at 75 C and treated afterwards with NH/sub 3/ in a fluidised-bed reactor in a temperature range 100-375 C. The effects of temperature, NH/sub 3/ flow rate, and reaction time on the total N/sub 2/ content of the product are reported. The product contained 7-13% wt of total N/sub 2/ which increased as the ammoniation temperature increased. Soil nitrification measurements of the N/sub 2/-enriched lignites showed that the maximum conversion to nitrates and rate of nitrification are exhibited by the product obtained at the lowest ammoniation temperature, i.e. 100 C. Maximum conversion to nitrates at that temperature was 45%, which compares well with similar products such as ammoniated peat (35%) and ammonium nitrohumates (45%).

Investigation of lignite and firewood co-combustion in a furnace for tobacco curing application  

SciTech Connect (OSTI)

Co-combustion of lignite and firewood was investigated for an application in tobacco curing industry in Northern Thailand. Extensive experiments have been carried out in a newly developed furnace suitable for small curing unit, in place of locally made furnace. The aim of this investigation is to evaluate the performance of the combustion chamber in the required thermal output range for tobacco curing and to examine the influence of fuel feed rate, fuel mixture ratio and air staging on the combustion and emission characteristics of the furnace during steady state operation. Their effects are characterized in terms of the observed variations of temperature distributions, emissions of CO, SO{sub 2}, CO{sub 2}, O{sub 2} and combustion efficiency. Co-firing of firewood and lignite has been found to exhibit acceptable temperature distribution, high combustion efficiency and low emissions over a wide thermal output span. Stable operation at low (50 kW) and high (150 kW) thermal output was achieved with average CO and SO{sub 2} content in flue gas typically below 1400 and 100 ppm, respectively. Under the conditions considered, it was showed that the fuel feed rate had greater influence on combustion and emissions than firewood and lignite mixture ratio and air staging.

Polygeneration-IGCC concepts for the production of hydrogen rich fuels based on lignite  

Science Journals Connector (OSTI)

This paper presents three IGCC-power plant concepts for central production of a hydrogen-rich fuel (methanol, hydrogen, synthetic natural gas â?? SNG) from lignite. Each concept contains a CO2-separation, which produces a sequestration-ready CO2-rich stream. Thus, CO2-emissions caused by use of lignite are considerably reduced. Furthermore, the produced low-carbon fuels are converted in decentralised Combined Heat and Power Plants (CHPP). CHPP leads to high efficiencies of fuel utilisation between 54 and 62%, which exceed the efficiencies of single power generation. Regarding to the CO2-emissions of a natural gas fired CHPP, heat and power can be generated by lignite as clean as by natural gas. The specific CO2-emissions are even much lower in the case of hydrogen production. Costs for the centrally produced methanol and hydrogen are with 29 and 19 EUR/MWh(LHV) already within an economic range. Synthetic natural gas can be produced for 23 EUR/MWh(LHV).

Production scheduling of a lignite mine under quality and reserves uncertainty  

Science Journals Connector (OSTI)

The effect of uncertainty sources to the stochastic optimization of the combined project of a new surface lignite mine exploitation and power plant operation for electricity generation is investigated. Major sources of uncertainty that were considered are the reserves and the quality of the lignite. Since probability distribution functions for these uncertainties were estimated during the detailed exploration phase of the deposit, the overall goal is then to determine the optimal capacity of the power plant and consequently the optimal production rate of the mine over the time. The optimization objective that was selected is the maximization of the net present value of the project. Emphasis is placed on the sensitivity analysis for the investigation of the effect of quality and reserves uncertainty on project optimization, on the mathematical formulation of risk attitude strategy and on increasing the efficiency of the optimization process by creating a limited set of feasible solutions applying empirical rules. The developed methodology was applied for the determination of the optimal annual production rate of a new surface lignite mine in the area of Ptolemais–Amynteon in Northern Greece.

Coal petrography, mineralogy and geochemistry of lignite samples from the Ogwashi–Asaba Formation, Nigeria  

Science Journals Connector (OSTI)

Organic sediments picked up randomly from seven small outcrops within the Ogwashi–Asaba Formation, southern Nigeria, are examined and evaluated by means of coal petrology and chemical and mineralogical analyses in order to determine the palaeoenvironmental conditions and the factors controlling their formation. Six samples proved to be low-rank coals C to B (lignite), one carbonaceous shale. The lignite samples display low ash yield, low telohuminite and high detrohuminite and liptinite contents; they contain small amounts of clastic minerals, mainly quartz and clays, which point to the topogenous character of the depositional palaeoenvironment. The palaeomires formed in a continental basin crossed by the mid-Tertiary palaeo-Niger River; the latter, as well as the tropical rainfall supplied the mires with water. The dense vegetation cover on the mire surface and the surroundings and/or the low relief energy of the broad area restricted the inorganic influx resulting in high-grade coal formation. As the outcrops are distributed over a distance of 60 km, the expected reserves of good quality lignite constitute a very promising exploration target.

Enhancing Carbon Reactivity in Mercury Control in Lignite-Fired Systems  

SciTech Connect (OSTI)

This project was awarded through the U.S. Department of Energy (DOE) National Energy Technology Laboratory Program Solicitation DE-PS26-03NT41718-01. The Energy & Environmental Research Center (EERC) led a consortium-based effort to resolve mercury (Hg) control issues facing the lignite industry. The EERC team-the Electric Power Research Institute (EPRI); the URS Corporation; the Babcock & Wilcox Company; ADA-ES; Apogee; Basin Electric Power Cooperative; Otter Tail Power Company; Great River Energy; Texas Utilities; Montana-Dakota Utilities Co.; Minnkota Power Cooperative, Inc.; BNI Coal Ltd.; Dakota Westmoreland Corporation; the North American Coal Corporation; SaskPower; and the North Dakota Industrial Commission-demonstrated technologies that substantially enhanced the effectiveness of carbon sorbents to remove Hg from western fuel combustion gases and achieve a high level ({ge} 55% Hg removal) of cost-effective control. The results of this effort are applicable to virtually all utilities burning lignite and subbituminous coals in the United States and Canada. The enhancement processes were previously proven in pilot-scale and limited full-scale tests. Additional optimization testing continues on these enhancements. These four units included three lignite-fired units: Leland Olds Station Unit 1 (LOS1) and Stanton Station Unit 10 (SS10) near Stanton and Antelope Valley Station Unit 1 (AVS1) near Beulah and a subbituminous Powder River Basin (PRB)-fired unit: Stanton Station Unit 1 (SS1). This project was one of three conducted by the consortium under the DOE mercury program to systematically test Hg control technologies available for utilities burning lignite. The overall objective of the three projects was to field-test and verify options that may be applied cost-effectively by the lignite industry to reduce Hg emissions. The EERC, URS, and other team members tested sorbent injection technologies for plants equipped with electrostatic precipitators (ESPs) and spray dryer absorbers combined with fabric filters (SDAs-FFs). The work focused on technology commercialization by involving industry and emphasizing the communication of results to vendors and utilities throughout the project.

Bibliography, geophysical data locations, and well core listings for the Mississippi Interior Salt Basin  

SciTech Connect (OSTI)

To date, comprehensive basin analysis and petroleum system modeling studies have not been performed on any of the basins in the northeastern Gulf of Mexico. Of these basins, the Mississippi Interior Salt Basin has been selected for study because it is the most petroliferous basin in the northeastern Gulf of Mexico, small- and medium-size companies are drilling the majority of the exploration wells. These companies do not have the resources to perform basin analysis or petroleum system modeling research studies nor do they have the resources to undertake elaborate information searches through the volumes of publicly available data at the universities, geological surveys, and regulatory agencies in the region. The Advanced Geologic Basin Analysis Program of the US Department of Energy provides an avenue for studying and evaluating sedimentary basins. This program is designed to improve the efficiency of the discovery of the nation`s remaining undiscovered oil resources by providing improved access to information available in the public domain and by increasing the amount of public information on domestic basins. This report provides the information obtained from Year 1 of this study of the Mississippi Interior Salt Basin. The work during Year 1 focused on inventorying the data files and records of the major information repositories in the northeastern Gulf of Mexico and making these inventories easily accessible in an electronic format.

Gulf Petro Initiative  

SciTech Connect (OSTI)

In this report, technologies for petroleum production and exploration enhancement in deepwater and mature fields are developed through basic and applied research by: (1) Designing new fluids to efficiently drill deepwater wells that can not be cost-effectively drilled with current technologies. The new fluids will be heavy liquid foams that have low-density at shallow dept to avoid formation breakdown and high density at drilling depth to control formation pressure. The goal of this project is to provide industry with formulations of new fluids for reducing casing programs and thus well construction cost in deepwater development. (2) Studying the effects of flue gas/CO{sub 2} huff n puff on incremental oil recovery in Louisiana oilfields bearing light oil. An artificial neural network (ANN) model will be developed and used to map recovery efficiencies for candidate reservoirs in Louisiana. (3) Arriving at a quantitative understanding for the three-dimensional controlled-source electromagnetic (CSEM) geophysical response of typical Gulf of Mexico hydrocarbon reservoirs. We will seek to make available tools for the qualitative, rapid interpretation of marine CSEM signatures, and tools for efficient, three-dimensional subsurface conductivity modeling.

Effect of potassium permanganate as an oxidizing agent in the production of lignite-based fertilizers  

SciTech Connect (OSTI)

The purpose of this work was to observe the effect of potassium permanganate oxidation of lignites from Elbistan for end use as fertilizers, after being ammoniated. The experiments at each stage were designed by a 1/2 x full factorial design. The oxidation was carried out by three different methods. In the first two methods potassium permanganate in neutral or basic medium was used. In the other method two stages of oxidation were used: nitric acid followed by potassium permanganate in acidic medium. The latter proved to be more successful.

The U.S. Geological Survey coal assessment of the Gulf Coastal region, a progress report  

SciTech Connect (OSTI)

The US Geological Survey (USGS) is conducting a comprehensive assessment of the major coal regions of the country. This program, known as the National Coal Resource Assessment (NCRA), is focused on five major coal-bearing regions in the country: the Appalachian basin, Illinois basin, Northern Rocky Mountains and Great Plains, Colorado Plateau, and the Gulf Coast region. In this program, the authors are characterizing the quantity and quality of coals that are expected to be mined during the next 30 years. As part of this effort, they are conducting an evaluation of the stratigraphic setting, resource potential, and the quality of the lignites in five coal-producing areas within the Gulf Coast region. The results of these efforts will be a series of digital Geographic Information System (GIS) maps, text, and tables that will be published in a CD-ROM format. These products, along with a national summary CD-ROM, are expected to be completed by 1999. The assessment of the Gulf Coast region is focused primarily on four areas that are currently producing coal as shown in a figure. These areas are the: (1) Sabine area, which includes parts of northwest Louisiana and northeast Texas; (2) northeast Texas; (3) central Texas; and (4) south Texas. In addition, a fifth area in Mississippi has been evaluated because a new surface mine has been proposed for that area. The Gulf Coast coal region produces about 57 million short tons of coal annually from the states of Louisiana and Texas from Wilcox Group coals. The primary intervals of study for this project are the Wilcox Group (Paleocene-Eocene) and selected coal-producing intervals (such as the Eocene Jackson and Claiborne Groups, and Cretaceous Olmos Formation in south Texas) that are producing or have potential for producing coal in the near future. The objectives of this project are to provide high-quality, organized information and interpretations on the location, quality, and quantity of the coal to be mined in the Gulf Coast area during the next several decades in order to meet the needs of the region for reliable, low cost, environmentally-acceptable energy.

Identification of organonitrogen compounds from thermally dissolved Huolinguole lignite in ethanol  

Science Journals Connector (OSTI)

Thermal dissolution of Huolinguole lignite (HL) in ethanol was conducted at 330°C for 2 h. The soluble fraction was sequentially eluted with petroleum ether (PE), ethyl acetate (EA)/PE mixed solvents with increased EA to PE ratio, and EA to afford five eluted fractions (EF1-EF5) through a silica gel-packed column. In total, 49 organonitrogen compounds (ONCs), including N-heterohexacyclic compounds (NHHCCs), N-heteropentacyclic compounds, nitrogen-containing group-substituted benzenes (NCGSBs), condensed N-heterocyclic compounds, and amides were detected in EF2 and EF3 with a gas chromatography/mass spectrometer. Among the ONCs, NHHCCs are dominant and most of them are alkyl pyridines (APs), suggesting that APs are the main existing modes of ONCs in HL. As the main NCGSBs, anilines may originally exist in HL or were released by HL ethanolysis. This investigation provides an effective approach for understanding the modes of ONC occurrences in lignites. [Received: April 11, 2013; Accepted: February 20, 2014

JV Task 117 - Impact of Lignite Properties on Powerspan's NOx Oxidation System  

SciTech Connect (OSTI)

Powerspan's multipollutant control process called electrocatalytic oxidation (ECO) technology is designed to simultaneously remove SO{sub 2}, NO{sub x}, PM{sub 2.5}, acid gases (such as hydrogen fluoride [HF], hydrochloric acid [HCl], and sulfur trioxide [SO{sub 3}]), Hg, and other metals from the flue gas of coal-fired power plants. The core of this technology is a dielectric barrier discharge reactor composed of cylindrical quartz electrodes residing in metal tubes. Electrical discharge through the flue gas, passing between the electrode and the tube, produces reactive O and OH radicals. The O and OH radicals react with flue gas components to oxidize NO to NO{sub 2} and HNO{sub 3} and a small portion of the SO{sub 2} to SO{sub 3} and H{sub 2}SO{sub 4}. The oxidized compounds are subsequently removed in a downstream scrubber and wet electrostatic precipitator. A challenging characteristic of selected North Dakota lignites is their high sodium content. During high-sodium lignite combustion and gas cooling, the sodium vaporizes and condenses to produce sodium- and sulfur-rich aerosols. Based on past work, it was hypothesized that the sodium aerosols would deposit on and react with the silica electrodes and react with the silica electrodes, resulting in the formation of sodium silicate. The deposit and reacted surface layer would then electrically alter the electrode, thus impacting its dielectric properties and NO{sub x} conversion capability. The purpose of this project was to determine the impact of lignite-derived flue gas containing sodium aerosols on Powerspan's dielectric barrier discharge (DBD) reactor with specific focus on the interaction with the quartz electrodes. Partners in the project were Minnkota Power Cooperative; Basin Electric Power Cooperative; Montana Dakota Utilities Co.; Minnesota Power; the North Dakota Industrial Commission, the Lignite Energy Council, and the Lignite Research Council; the Energy & Environmental Research Center (EERC); and the U.S. Department of Energy. An electrocatalytic oxidation (ECO) reactor slipstream system was designed by Powerspan and the EERC. The slipstream system was installed by the EERC at Minnkota Power Cooperative's Milton R. Young Station Unit 1 downstream of the electrostatic precipitator where the flue gas temperature ranged from 300 to 350 F. The system was commissioned on July 3, 2007, operated for 107 days, and then winterized upon completion of the testing campaign. Operational performance of the system was monitored, and data were archived for postprocessing. A pair of electrodes were extracted and replaced on a biweekly basis. Each pair of electrodes was shipped to Powerspan to determine NO conversion efficiency in Powerspan's laboratory reactor. Tested electrodes were then shipped to the EERC for scanning electron microscopy (SEM) and x-ray microanalysis. Measurement of NO{sub x} conversion online in operating the slipstream system was not possible because the nitric and sulfuric acid production by the DBD reactor results in conditioning corrosion challenges in the sample extraction system and NO measurement technologies. The operational observations, performance results, and lab testing showed that the system was adversely affected by accumulation of the aerosol materials on the electrode. NO{sub x} conversion by ash-covered electrodes was significantly reduced; however, with electrodes that were rinsed with water, the NOx conversion efficiency recovered to nearly that of a new electrode. In addition, the visual appearance of the electrode after washing did not show evidence of a cloudy reacted surface but appeared similar to an unexposed electrode. Examination of the electrodes using SEM x-ray microanalysis showed significant elemental sodium, sulfur, calcium, potassium, and silica in the ash coating the electrodes. There was no evidence of the reaction of the sodium with the silica electrodes to produce sodium silicate layers. All SEM images showed a clearly marked boundary between the ash and the silica. Sodium and sulfur are the main culprits in the

Air and oxy-fuel combustion behaviour of petcoke/lignite blends  

Science Journals Connector (OSTI)

The pyrolysis and combustion behaviour of a petroleum coke (petcoke), an indigenous lignite and their 70/30 wt.% blend in air and oxy-fuel conditions were investigated by using non-isothermal thermo-gravimetric method (TGA) coupled with Fourier transform infrared (FTIR) spectrometer. Blend samples were prepared by mixing lignite, which has low calorific value, high ash and moisture contents with petcoke that has high calorific value, low ash and moisture content, in the proportion of 70:30. Pyrolysis tests were carried out in nitrogen and carbon dioxide environments which are the main diluting gases of air and oxy-fuel environments, respectively. Pyrolysis curves of parent fuels and their blend reveal close resemblance up to 700 °C in both N2 and CO2 environments. At higher temperatures, further weight loss taking place in N2 and CO2 atmospheres is attributed to calcite decomposition and CO2-char gasification reaction, respectively. Gasification reaction leads to significant increase in CO and COS formation as observed in FTIR evolution profiles. Almost identical experimental and theoretical pyrolysis profiles of the blend samples show that there is no synergy between the parent fuels of the blend in both pyrolysis environments. Combustion experiments were carried out in four different atmospheres; air, oxygen-enriched air environment (30% O2–70% N2), oxy-fuel environment (21% O2–79% CO2) and oxygen-enriched oxy-fuel environment (30% O2–70% CO2). Combustion experiments show that replacing nitrogen in the gas mixture by the same concentration of CO2 leads to delay in combustion (lower maximum rate of weight loss and higher burnout temperatures). Overall comparison of derivative thermogravimetry (DTG) profiles shows that effect of oxygen content on combustion characteristics is more significant than that of diluting gas in the combustion environment. At elevated oxygen levels, profiles shift through lower temperature zone, peak and burnout temperatures decrease, weight loss rate increases significantly and complete combustion is achieved at lower temperatures and shorter times. Theoretical and experimental combustion profiles of the blend mainly display different trends, which indicate synergistic interactions between lignite and petcoke during their combustion in different environments.

Simulation study on lignite-fired power system integrated with flue gas drying and waste heat recovery – Performances under variable power loads coupled with off-design parameters  

Science Journals Connector (OSTI)

Abstract Lignite is a kind of low rank coal with high moisture content and low net heating value, which is mainly used for electric power generation. However, the thermal efficiency of power plants firing lignite directly is very low. Pre-drying is a proactive option, dehydrating raw lignite to raise its heating value, to improve the power plant thermal efficiency. A pre-dried lignite-fired power system integrated with boiler flue gas drying and waste heat recovery was proposed in this paper. The plant thermal efficiency could be improved by 1.51% at benchmark condition due to pre-drying and waste heat recovery. The main system performances under variable power loads were simulated and analyzed. Simulation results show that the improvement of plant thermal efficiency reduced to 1.36% at 50% full load. Moreover, the influences of drying system off-design parameters were simulated coupled with power loads. The variation tendencies of main system parameters were obtained. The influence of pre-drying degree (including moisture content of pre-dried lignite and raw lignite) on the plant thermal efficiency diminishes gradually with the decreasing power load. The dryer thermal efficiency and dryer exhaust temperature are also main factors and the influences on system parameters have been quantitatively analyzed.

The effect of quality and reserves uncertainty to production scheduling of a lignite mine feeding a power plant  

Science Journals Connector (OSTI)

The effect of uncertainty sources to the stochastic optimization of the combined project of a new surface lignite mine exploitation and power plant operation for electricity generation is investigated. Major sources of uncertainty that were considered are the reserves and the quality of the lignite. Since probability distribution functions for these uncertainties were estimated during the detailed exploration phase of the deposit, the overall goal is then to determine the optimal capacity of the power plant and consequently the optimal production rate of the mine over the time. The optimization objective that was selected is the maximization of the expected net present value of the project. Emphasis is placed on the mathematical analysis applied for the investigation of the effect of the two main parameters in project optimization.

Crude Oil Imports From Persian Gulf  

Gasoline and Diesel Fuel Update (EIA)

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

Future gulf dynamics and US security  

SciTech Connect (OSTI)

This documental briefing synthesizes the results of a research project, entitled 'Future Security Requirements for the Gulf.' It represents an effort to pull together much of the detailed work conducted during this project and focuses on the principal factors driving the future environment in the greater Gulf region, on the implications of the resulting findings for future Gulf security and for the U.S. regional posture in the area, and on a broad examination of alternative U.S. approaches to its security in the Gulf. The overall project objective was to provide a political-military assessment of security prospects in the Gulf over the next 3 to 5 years, challenges the U.S. military are likely to encounter as they support U.S. national objectives in the region, and the broader implications for future U.S. security planning.

Large-Scale Mercury Control Technology Testing for Lignite-Fired Utilities - Oxidation Systems for Wet FGD  

SciTech Connect (OSTI)

Mercury (Hg) control technologies were evaluated at Minnkota Power Cooperative's Milton R. Young (MRY) Station Unit 2, a 450-MW lignite-fired cyclone unit near Center, North Dakota, and TXU Energy's Monticello Steam Electric Station (MoSES) Unit 3, a 793-MW lignite--Powder River Basin (PRB) subbituminous coal-fired unit near Mt. Pleasant, Texas. A cold-side electrostatic precipitator (ESP) and wet flue gas desulfurization (FGD) scrubber are used at MRY and MoSES for controlling particulate and sulfur dioxide (SO{sub 2}) emissions, respectively. Several approaches for significantly and cost-effectively oxidizing elemental mercury (Hg{sup 0}) in lignite combustion flue gases, followed by capture in an ESP and/or FGD scrubber were evaluated. The project team involved in performing the technical aspects of the project included Babcock & Wilcox, the Energy & Environmental Research Center (EERC), the Electric Power Research Institute, and URS Corporation. Calcium bromide (CaBr{sub 2}), calcium chloride (CaCl{sub 2}), magnesium chloride (MgCl{sub 2}), and a proprietary sorbent enhancement additive (SEA), hereafter referred to as SEA2, were added to the lignite feeds to enhance Hg capture in the ESP and/or wet FGD. In addition, powdered activated carbon (PAC) was injected upstream of the ESP at MRY Unit 2. The work involved establishing Hg concentrations and removal rates across existing ESP and FGD units, determining costs associated with a given Hg removal efficiency, quantifying the balance-of-plant impacts of the control technologies, and facilitating technology commercialization. The primary project goal was to achieve ESP-FGD Hg removal efficiencies of {ge}55% at MRY and MoSES for about a month.

Gulf Cooperation Council: search for security in the Persian Gulf  

SciTech Connect (OSTI)

This study purports to analyze the conservative Arab monarchies' search for regional security in the Persian Gulf. It speculates on the GCC's future prospects as a vehicle of cooperation in the field of security. Threats to the member states of the GCC stem from the policies pursued by revolutionary Iran, Israel, the Soviet Union and its proxies, and a regime in Iraq. The proposition is developed that these sources of threat present an overwhelming challenge to the security and stability of GCC states. Second, it examines the capabilities of the GCC member states for coping with threats. Conceived broadly, both military and non-military capabilities are examined. Security relations of the GCC states with external powers as a means of enhancing their abilities to cope more effectively with both internal and external threats are examined. Particular attention is devoted to the domestic consequences of these special relations. Third, it discusses the GCC's reactions to perceived regional threats. These include the Iran-Iraq War, the Arab-Israeli conflict, the Soviet threat, and potential political sources of dissidence in member states. It is argued that although GCC states have adopted a number of joint policies, they did not respond to or initiate action on either the Iranian Revolution, the Palestine conflict, the Soviet occupation of Afghanistan, the Gulf war or the recent Israeli invasion of Lebanon.

PILOT-AND FULL-SCALE DEMONSTRATION OF ADVANCED MERCURY CONTROL TECHNOLOGIES FOR LIGNITE-FIRED POWER PLANTS  

SciTech Connect (OSTI)

North Dakota lignite-fired power plants have shown a limited ability to control mercury emissions in currently installed electrostatic precipitators (ESPs), dry scrubbers, and wet scrubbers (1). This low level of control can be attributed to the high proportions of Hg{sup 0} present in the flue gas. Speciation of Hg in flue gases analyzed as part of the U.S. Environmental Protection Agency (EPA) information collection request (ICR) for Hg data showed that Hg{sup 0} ranged from 56% to 96% and oxidized mercury ranged from 4% to 44%. The Hg emitted from power plants firing North Dakota lignites ranged from 45% to 91% of the total Hg, with the emitted Hg being greater than 85% elemental. The higher levels of oxidized mercury were only found in a fluidized-bed combustion system. Typically, the form of Hg in the pulverized and cyclone-fired units was dominated by Hg{sup 0} at greater than 85%, and the average amount of Hg{sup 0} emitted from North Dakota power plants was 6.7 lb/TBtu (1, 2). The overall objective of this Energy & Environmental Research Center (EERC) project is to develop and evaluate advanced and innovative concepts for controlling Hg emissions from North Dakota lignite-fired power plants by 50%-90% at costs of one-half to three-fourths of current estimated costs. The specific objectives are focused on determining the feasibility of the following technologies: Hg oxidation for increased Hg capture in wet and dry scrubbers, incorporation of additives and technologies that enhance Hg sorbent effectiveness in ESPs and baghouses, the use of amended silicates in lignite-derived flue gases for Hg capture, and the use of Hg adsorbents within a baghouse. The scientific approach to solving the problems associated with controlling Hg emissions from lignite-fired power plants involves conducting testing of the following processes and technologies that have shown promise on a bench, pilot, or field scale: (1) activated carbon injection (ACI) upstream of an ESP combined with sorbent enhancement, (2) Hg oxidation and control using wet and dry scrubbers, (3) enhanced oxidation at a full-scale power plant using tire-derived fuel (TDF) and oxidizing catalysts, and (4) testing of Hg control technologies in the Advanced Hybrid{trademark} filter insert.

The Sun's Interior Metallicity Constrained by Neutrinos  

E-Print Network [OSTI]

Observed solar neutrino fluxes are employed to constrain the interior composition of the Sun. Including the effects of neutrino flavor mixing, the results from Homestake, Sudbury, and Gallium experiments constrain the Mg, Si, and Fe abundances in the solar interior to be within a factor 0.89 to 1.34 of the surface values with 68% confidence. If the O and/or Ne abundances are increased in the interior to resolve helioseismic discrepancies with recent standard solar models, then the nominal interior Mg, Si, and Fe abundances are constrained to a range of 0.83 to 1.24 relative to the surface. Additional research is needed to determine whether the Sun's interior is metal poor relative to its surface.

Effect of environment atmosphere on the sintering of Thai lignite fly ashes  

SciTech Connect (OSTI)

Sintering of ash particles, related to deposit formation in a pulverized coal-fired boiler, was investigated for two lignite fly ashes obtained from Mae Moh and Bangpudum coal seams. The tests involved measuring the compressive strength of cold sintered pellets at varying sintering temperature, both under oxidizing (air) and non-oxidizing atmospheres (CO{sub 2}). Under ambient air condition, Mae Moh fly ash which contained higher amount of glassy phase gave significantly higher sinter strength than Bangpudum fly ash. The role of glassy phase was confirmed by the lowering of sinter strength when HF-extracted fly ash was tested. Sintering under CO{sub 2} environment resulted in larger strength development than sintering in air. Under this non-oxidizing condition, the pellet color turned black, indicating that most of the iron was in the reduced state and could form additional low melting-point glassy phase, hence facilitated sintering rate. In addition, blending of the two ashes yielded intermediate maximum strength, under both air and CO{sub 2} environments. This observation substantiates the important role of glassy phase in the sintering process and indicates the possibility of lowering deposit strength by judicious mixing of different raw coal feeds.

Dragonflies of freshwater pools in lignite spoil heaps: Restoration management, habitat structure and conservation value  

Science Journals Connector (OSTI)

Although numerous studies of several terrestrial groups have revealed high conservation potential of post-industrial sites, freshwater habitats in post-mining sites still remain little explored. Here we present a study of dragonflies (Odonata) colonizing 61 freshwater pools newly established at 9 lignite spoil heaps in the north-western Czech Republic, Central Europe. We aimed mainly on effects of the three prevailing pool restoration methods (spontaneously inundated depressions at non-reclaimed sites, at reclaimed sites; and novel technically constructed ponds) along with several factors of the local habitat and surrounding landscape on species richness, conservation values, and species composition of the dragonfly communities. By recording of 32 species of lentic dragonflies (including 8 threatened ones) and 2 additional threatened lotic species, we documented the conservation value of post-industrial habitats also for aquatic arthropods. None of the three restoration methods supported dragonfly communities of distinctly higher conservation value then did the two others, each method generated habitats for different threatened species. Similar patterns were revealed also for vegetation heterogeneity, bottom substrate, water shading, and surrounding terrestrial habitats. We thus conclude that a mosaic-like combination of the restoration methods and creating of heterogeneous water pools will be most effective for restoring of freshwater biodiversity in highly degraded sites.

Vegetation trends in reclaimed areas at Gibbons Creek Lignite Mine, Grimes County, Texas  

SciTech Connect (OSTI)

Vegetation productivity and cover studies have been conducted annually at the Gibbons Creek Lignite Mine since 1989, and multiple annual clippings have been collected since 1991. The primary purpose of these studies was to examine revegetation success, in terms of herbaceous productivity, for various post-mine soil types. However, the studies also contain detailed information on species composition. For the years in which multiple annual clippings have been collected (1991 through 1996), total vegetation cover increased, with the mean proportion of bare ground dropping from 12% in 1991 to 1% in 1996. Relative proportions of most introduced and native grasses were virtually static from 1991 through 1994; in 1995, however, herbicide applications to reduce clover cover resulted in a dramatic increase in total grass cover, especially in bahiagrass (Paspalum notatum) and Indiangrass (Sorgastrum nutans). In contrast to the trends of other introduced and native grasses, bahiagrass increased in cover throughout the study period, increasing from 7% in 1991 to 21 % in 1996. Annual and weedy grass species decreased in cover throughout the study period, falling from 12% cover in 1991 to 2% in 1996. This trend of displacement of annuals by perennials is typically observed during ecological succession in natural vegetation communities, and appears to have been accelerated by the herbicide application.

Coal facies in a Cenozoic paralic lignite bed, Krabi Basin, southern Thailand: Changing peat-forming conditions related to relative sea-level controlled watertable variations  

Science Journals Connector (OSTI)

The Cenozoic Krabi Basin in the southern part of peninsular Thailand contains about 112 million tons proven coal reserves. At present, coal is only produced from the Bang Mark mine located in the southern part of the basin, where the main lignite bed is 7–20 m thick. The lignite bed occurs in an overall paralic succession. The present paper investigates the depositional conditions of an approximately 8 m thick lignite bed (main seam) in the Bang Mark mine using organic petrography, including maceral ratios, and geochemistry. The results are further interpreted in a sequence stratigraphic context. The lignite is of low rank and is completely dominated by huminite indicating generally oxygen-deficient conditions in the precursor mire. Very low inertinite contents suggest rare occurrences of wildfires. The lower part of the lignite bed represents a topogenous fresh water peat mire with open water areas that in few cases may have experienced influx of saline water. The peat mire was subjected to periodic inundations and deposition of siliciclastics. Tissue preservation was relatively poor. The upper part of the lignite bed represents a slightly domed fresh water ombrogenous peat mire with a stable watertable and a balance between peat accumulation and accommodation space creation that favoured preservation of plant tissues. In general, the mire vegetation changed from less woody in the topogenous mire to more arborescent in the ombrogenous mire, where plants with suberinised wood cell walls also were more frequent. Decompacted, the lignite bed corresponds to a minimum ~ 11 m thick peat deposit that records from ~ 22,000 to 55,000 years of peat accumulation. Watertable rise in the peat mire was controlled overall by relative sea-level rise. In a sequence stratigraphic context, the lignite bed overlies a terrestrialisation surface (TeS; sensu Diessel, 2007) and the lowermost part records peat formation during a falling watertable and a decreasing accommodation/peat accumulation ratio (terrestrialisation). An accommodation reversal surface (ARS; sensu Diessel, 2007) indicates a change to paludification style of peat formation characterised by rising watertable and a high accommodation/peat accumulation ratio. Another ARS marks a gradual change to a situation with a balanced accommodation/peat accumulation ratio. The overall watertable rise throughout peat formation, but at a gradually slower rate from base to top, suggests that the lignite bed could be located in the late transgressive systems tract (TST).

Regional Refinery Utilization Shows Gulf Coast Pressure  

Gasoline and Diesel Fuel Update (EIA)

5 5 Notes: But there is some room for hope. Refineries generally begin maintenance in February or March, and finish in April. The East Coast was experiencing some lengthy refinery maintenance outages, as shown by the drop in utilization that remained low in most of March and April. In the meantime, the East Coast was drawing on extra supplies from the Gulf Coast and imports. The Midwest refineries seem to have been ramping up in April as they finished what maintenance was needed. But the Midwest no longer has the Blue Island refinery, so it also is pulling more product from the Gulf Coast. The high Gulf Coast prices this spring reflect extra "pull" on product from both the Midwest and the East Coast, and probably from California as well.

Gasification of lignite in a fixed bed reactor: Influence of particle size on performance of downdraft gasifier  

Science Journals Connector (OSTI)

Abstract In this work, an experimental study of the gasification of lignite with various particle sizes was carried out in a pilot-scale (10 kWe) downdraft type fixed bed gasifier. The main objective of the study was to investigate the feasibility of the lignite as a fuel for downdraft gasifier and to evaluate the effect of the particle size on gasifier performance. The influence of the particle size on fuel consumption rate, temperature profile in various zone, gas yield, gas composition and cold gas efficiency was studied. Six different particle sizes viz. 13–16 mm, 16–19 mm, 19–22 mm, 22–25 mm, 25–28 mm, 28–31 mm were selected for experimental work. With the increase in particle size, the reduction in fuel consumption rate was observed, whereas the producer gas production rate had increased. The heating value of the gas increased as particle size increased from 13–16 mm to 22–25 mm and then same had decreased with increase in particle size. Higher temperature in reduction zone resulted in higher H2 and CO contents in producer gas. Under the experiment conditions, the fuel consumption rate, gas yields, LHV (Lower heating value) of gas fuel and cold gas efficiency varied in the range of 9.58–10.67 kg/hr, 2.43–2.63 Nm3/kg, 3.33–4.17 MJ/Nm3 and 51.5%–65.7% respectively. The experimental results showed that the gasification performance was better with lignite particle size of 22–25 mm.

Transformation of alkali metals during pyrolysis and gasification of a lignite  

SciTech Connect (OSTI)

Transformation of Na and K in a lignite was investigated during pyrolysis and gasification in a fixed-bed by using a serial dissolution method with H{sub 2}O, CH{sub 3}COONH{sub 4}, and HCl solutions. The evolution of the fractions of four forms in solid and alkali volatilization during pyrolysis and gasification was determined. The results show that a different mode of occurrence between Na and of K in coal existed. Na in coal can be nearly completely dissolved by H{sub 2}O, CH{sub 3}COONH{sub 4}, and HCl solution. However, K in coal exists almost in the stable forms. Both H{sub 2}O soluble and CH{sub 3}COONH{sub 4} soluble Na and K fractions decline during pyrolysis and early gasification stage and increase a little with the process of char gasification. The stable form Na in the char produced during pyrolysis is transferred to other forms during char gasification via the pore opening and a series of chemical reactions. Na{sub 2}SO{sub 4} (K{sub 2}SO{sub 4}) may play an important role in producing stable forms such as Na{sub 2}O.Al{sub 2}O{sub 3}2SiO{sub 2} and K{sub 2}O.Al{sub 2}O{sub 3}.2SiO{sub 2} during pyrolysis. The fraction of HCl soluble K increases during pyrolysis but decreases markedly during the early gasification stage. 20 refs., 7 figs., 1 tabs.

Correlation of Paleocene Harmon and Hansen lignite beds, Adams, Billings, Bowman, Golden Valley, Hettinger, and Slope Counties, Williston Basin, North Dakota  

SciTech Connect (OSTI)

In southwestern North Dakota, minable lignite beds in the Paleocene Fort Union Formation include the Harmon and Hansen beds in the Bowman-Gascoyne area. Data from more than 700 drill holes penetrating these beds was used to construct stratigraphic cross sections. The Harmon and Hansen beds are the thickest and most laterally persistent lignites found under < 150 ft of overburden. The Harmon coal bed is as much as 34 ft thick, and is often split by claystone interbeds of variable thickness. The Hansen coal bed typically occurs 10--100 ft below the Harmon coal bed; it rarely attains a thickness of 15 ft, and averages 4 ft in thickness.

POWDERED ACTIVATED CARBON FROM NORTH DAKOTA LIGNITE: AN OPTION FOR DISINFECTION BY-PRODUCT CONTROL IN WATER TREATMENT PLANTS  

SciTech Connect (OSTI)

New federal drinking water regulations have been promulgated to restrict the levels of disinfection by-products (DBPs) in finished public water supplies. DBPs are suspected carcinogens and are formed when organic material is partially oxidized by disinfectants commonly used in the water treatment industry. Additional federal mandates are expected in the near future that will further affect public water suppliers with respect to DBPs. Powdered activated carbon (PAC) has traditionally been used by the water treatment industry for the removal of compounds contributing to taste and odor problems. PAC also has the potential to remove naturally occurring organic matter (NOM) from raw waters prior to disinfection, thus controlling the formation of regulated DBPs. Many small water systems are currently using PAC for taste and odor control and have the potential to use PAC for controlling DBPs. This project, a cooperative effort between the Energy & Environmental Research Center (EERC), the Grand Forks Water Treatment Plant, and the University of North Dakota Department of Civil Engineering, consists of several interrelated tasks. The objective of the research was to evaluate a cost-effective PAC produced from North Dakota lignite for removing NOM from water and reducing trihalomethane formation potential. The research approach was to develop a statistically valid testing protocol that can be used to compare dose-response relationships between North Dakota lignite-derived PAC and commercially available PAC products. A statistical analysis was performed to determine whether significant correlations exist between operating conditions, water properties, PAC properties, and dose-response behavior. Pertinent physical and chemical properties were also measured for each of the waters and each of the PACs.

United States military strategy in the Persian Gulf. Study project  

SciTech Connect (OSTI)

The importance of Persian Gulf oil, in the context of United States national security has been demonstrated in recent political, economic, and military terms. Substantial United States military resources have been devoted to maintain national security interests in the Persian Gulf region. This paper analyzes the United States military strategy designed to insure the US and its allies continued access to Persian Gulf oil and to suggest alternatives for possible improvement. Although the focus is on US military strategy in the Persian Gulf, it also covers others aspects of US national security policy and strategy. US military policy in the Persian Gulf is derived from a complex process that inextricably links the elements of national strategy with the elements of national power. Conclusions about US policy and strategy in the Persian Gulf that are properly focused and logical require an understanding of US interests and their priorities; US strategies and their feasibility; plus US capabilities and their limitations.

Recent advances in modeling stellar interiors (u)  

SciTech Connect (OSTI)

Advances in stellar interior modeling are being driven by new data from large-scale surveys and high-precision photometric and spectroscopic observations. Here we focus on single stars in normal evolutionary phases; we will not discuss the many advances in modeling star formation, interacting binaries, supernovae, or neutron stars. We review briefly: (1) updates to input physics of stellar models; (2) progress in two and three-dimensional evolution and hydrodynamic models; (3) insights from oscillation data used to infer stellar interior structure and validate model predictions (asteroseismology). We close by highlighting a few outstanding problems, e.g., the driving mechanisms for hybrid {gamma} Dor/{delta} Sct star pulsations, the cause of giant eruptions seen in luminous blue variables such as {eta} Car and P Cyg, and the solar abundance problem.

Geology of interior cratonic sag basins  

SciTech Connect (OSTI)

Interior cratonic sag basins are thick accumulations of sediment, generally more or less oval in shape, located entirely in the interiors of continental masses. Some are single-cycle basins and others are characterized by repeated sag cycles or are complex polyhistory basins. Many appear to have developed over ancient rift systems. Interior cratonic sag basins are typified by a dominance of flexural over fault-controlled subsidence, and a low ratio of sediment volume to surface area of the basin. The Baltic, Carpentaria, Illinois, Michigan, Parana, Paris, and Williston basins are examples of interior cratonic sag basins. Tectonics played a dominant role in controlling the shapes and the geometries of the juxtaposed packets of sedimentary sequences. While the mechanics of tectonic control are not clear, evidence suggests that the movements are apparently related to convergence of lithospheric plates and collision and breakup of continents. Whatever the cause, tectonic movements controlled the freeboard of continents, altering base level and initiating new tectono-sedimentologic regimes. Sag basins situated in low latitudes during their development commonly were sites of thick carbonates (e.g., Illinois, Michigan, Williston, and Paris basins). In contrast, siliciclastic sedimentation characterized basins that formed in higher latitudes (e.g., Parana and Carpentaria basins). Highly productive sag basins are characterized by widespread, mature, organic-rich source rocks, large structures, and good seals. Nonproductive basins have one or more of the following characteristics: immature source rocks, leaky plumbing, freshwater flushing, and/or complex geology due to numerous intrusions that inhibit mapping of plays.

Western economies and the Gulf war  

SciTech Connect (OSTI)

A prolonged Iran/Iraq war could mean economic and even political-military disaster for western countries dependent on Persian Gulf oil. The percentage of gross national product loss that the US, western Europe, and Japan would suffer is estimated for three levels of interruption and illustrates how global effects can be felt even when direct imports are not involved. Although the US has few options for projecting power into the Gulf region, a long-run expansion of military capability is essential. The economic damage of continued disruptions can be eased by using more coal, nuclear power, and natural gas even if it means removing some environmental and economic barriers. A combination of financial incentives and additions to the strategic oil and gas storage would help, but important change will come from a reappraisal of our military position. (DCK)

Characterization of the liquid phase obtained by copyrolysis of Mustafa Kemal Pasa (M.K.P.) Lignite (Turkey) with low density polyethylene  

SciTech Connect (OSTI)

This study describes the detailed hydrocarbon type characterization of the tar (liquid phase) obtained by copyrolysis of Mustafa Kemal Paa (M.K.P.) lignite (Turkey) and low density polyethylene (LDPE) and by pyrolysis of coal and LDPE individually. Various spectroscopic techniques (gas chromatography-mass spectroscopy (GC-MS), nuclear magnetic resonance spectroscopy ({sup 1}H NMR), Fourier transform infrared spectroscopy (FTIR), and gel permeation chromatography (GPC)) are used for characterization, and the effect of the experimental conditions (temperature, lignite:low density polyethylene (LDPE) ratio, and catalyst) on the hydrocarbon distributions is discussed. The results show that the tars obtained by copyrolysis have similar properties with commercial gasoline (especially in the presence of Red mud). Red mud and bentonite used as catalysts make a positive effect on the production of olefins instead aromatics. Polyethylene acts as a hydrogenation medium for the coal product as revealed by FTIR results. 18 refs., 9 figs., 5 tabs.

Grand Gulf-prioritization of regulatory requirements  

SciTech Connect (OSTI)

As cost pressures mount, Grand Gulf nuclear station (GGNS) is relying increasingly on various prioritization approaches to implement, modify, eliminate, or defer regulatory requirements. Regulatory requirements can be prioritized through the use of three measures: (1) safety (or risk) significance; (2) cost; and (3) public policy (or political) significance. This paper summarizes GGNS' efforts to implement solutions to regulatory issues using these three prioritization schemes to preserve a balance between cost and safety benefit.

Effect of experimental conditions on the yields during the copyrolysis of Mustafa Kemal Paa (MKP) Lignite (Turkey) with low-density polyethylene  

SciTech Connect (OSTI)

Copyrolysis of a Turkish lignite with low-density polyethylene (LDPE) is conducted in a tubular reactor. The effect of experimental conditions (temperature of 400-700{sup o}C, catalyst, LDPE contents of the mixture are 33, 50, and 67 wt %) on the formation of tar, gas, and char and their effects on the formation of phenol are investigated. The catalysts used are red mud (which is a waste product of an aluminum factory in Turkey), zeolite (Linde type A (LTA)), and K{sub 2}CO{sub 3}. Tar evolution is determined to be increased significantly by increasing the LDPE content of the coal-LDPE mixture during the pyrolysis. The effect of adding LDPE to the coal on the gas generation is not remarkable. An increase in temperature leads to increased gas yields. Phenol and phenol derivatives are the obstacles for the complete conversion of lignite to tar and gas. To investigate this negative effect of phenols on the yields, the phenols found in tar from coal pyrolysis are detected by gas chromatography-mass spectroscopy (GC-MS), and it is observed that phenolic structures detected in the tar obtained by individual pyrolysis of coal are dramatically decreased by adding polymer to the coal. The use of catalysts during the copyrolysis procedure leads to improved gas generation. The possible reasons of these variations are discussed. A remarkable synergetic effect between lignite and LDPE on the tar yields is also observed. 21 refs., 8 figs., 4 tabs.

Kinetic study of steam gasification of two mineralogically different lignite chars: An active site/intermediate model  

Science Journals Connector (OSTI)

Abstract A new active site/intermediate model (ASIM) is formulated in terms of a simplified calcium-catalyzed mechanism of char gasification to characterize a conversion-dependent maximum in reaction rate. In a limited case, the model is retrogressed to a common volumetric model (VM). Two sets of kinetic data were experimentally gathered by steam gasification of two lignite chars in a fixed bed reactor with negligible mass diffusion limitation. The gasification behaviors of two chars were, respectively, representative of catalyzed and uncatalyzed gasification as a result of the influences of different mineral components in them. It was found that ASIM intimately fit the kinetic profiles over the entire range of conversion for both catalyzed and uncatalyzed char gasification, demonstrating the good adaptability to varying chars. The model could determine the activation energies for the formation of the total carbon-containing gases and of two individual gases (CO and CO2) from the oxygenated intermediate. Moreover, for the case of catalyzed gasification, ASIM reasonably predicted the formation, growth and decline of the intermediate with carbon conversion as well as the change in the intermediate concentration with gasification temperature. For the case of uncatalyzed gasification, the model portrayed essentially a linear decline in the intermediate concentration with increasing carbon conversion, similar to VM.

An initial study on feasible treatment of Serbian lignite through utilization of low-rank coal upgrading technologies  

Science Journals Connector (OSTI)

Abstract Despite benefiting from vast fuel reserves, combustion of low-rank coals is commonly characterized by low thermal efficiency and high pollutant emissions, partly due to high moisture content of the coals in question. Thus, removal of moisture from low-rank coals is deemed an important quality upgrading method. The paper provides an overview of the current status of low-rank coal upgrading technologies, particularly with respect to utilization of drying and dewatering procedures. In order to examine the influence of relevant parameters on the moisture removal process, a model of convective coal drying in a packed, as well as in a fluid bed combustion arrangement, is developed and presented. Product-specific data (intraparticle mass transfer, gas–solid moisture equilibrium) related to the coal variety addressed herein (lignite) are obtained through preliminary investigations. Effective thermal conductivity of the packed bed as defined by Zehner/Bauer/Schlünder is used to define heat transfer mechanisms occurring in the packed bed. Similar two-phase fluidization model has been validated for different types of biomaterials.

BASIN ANALYSIS AND PETROLEUM SYSTEM CHARACTERIZATION AND MODELING, INTERIOR SALT BASINS, CENTRAL AND EASTERN GULF OF MEXICO  

SciTech Connect (OSTI)

The principal research effort for Year 2 of the project has been data compilation and the determination of the burial and thermal maturation histories of the North Louisiana Salt Basin and basin modeling and petroleum system identification. In the first nine (9) months of Year 2, the research focus was on the determination of the burial and thermal maturation histories, and during the remainder of the year the emphasis has basin modeling and petroleum system identification. Existing information on the North Louisiana Salt Basin has been evaluated, an electronic database has been developed, regional cross sections have been prepared, structure and isopach maps have been constructed, and burial history, thermal maturation history and hydrocarbon expulsion profiles have been prepared. Seismic data, cross sections, subsurface maps and related profiles have been used in evaluating the tectonic, depositional, burial and thermal maturation histories of the basin. Oil and gas reservoirs have been found to be associated with salt-supported anticlinal and domal features (salt pillows, turtle structures and piercement domes); with normal faulting associated with the northern basin margin and listric down-to-the-basin faults (state-line fault complex) and faulted salt features; and with combination structural and stratigraphic features (Sabine and Monroe Uplifts) and monoclinal features with lithologic variations. Petroleum reservoirs are mainly Upper Jurassic and Lower Cretaceous fluvial-deltaic sandstone facies and Lower Cretaceous and Upper Cretaceous shoreline, marine bar and shallow shelf sandstone facies. Cretaceous unconformities significantly contribute to the hydrocarbon trapping mechanism capacity in the North Louisiana Salt Basin. The chief petroleum source rock in this basin is Upper Jurassic Smackover lime mudstone beds. The generation of hydrocarbons from Smackover lime mudstone was initiated during the Early Cretaceous and continued into the Tertiary. Hydrocarbon expulsion commenced during the Early Cretaceous and continued into the Tertiary with peak expulsion occurring mainly during the Late Cretaceous.

3-D seismology in the Arabian Gulf  

SciTech Connect (OSTI)

Since 1977 when Aramco and GSI (Geophysical Services International) pioneered the first 3-D seismic survey in the Arabian Gulf, under the guidance of Aramco`s Chief Geophysicist John Hoke, 3-D seismology has been effectively used to map many complex subsurface geological phenomena. By the mid-1990s extensive 3-D surveys were acquired in Abu Dhabi, Oman, Qatar and Saudi Arabia. Also in the mid-1990`s Bahrain, Kuwait and Dubai were preparing to record surveys over their fields. On the structural side 3-D has refined seismic maps, focused faults and fractures systems, as well as outlined the distribution of facies, porosity and fluid saturation. In field development, 3D has not only reduced drilling costs significantly, but has also improved the understanding of fluid behavior in the reservoir. In Oman, Petroleum Development Oman (PDO) has now acquired the first Gulf 4-D seismic survey (time-lapse 3D survey) over the Yibal Field. The 4-D survey will allow PDO to directly monitor water encroachment in the highly-faulted Cretaceous Shu`aiba reservoir. In exploration, 3-D seismology has resolved complex prospects with structural and stratigraphic complications and reduced the risk in the selection of drilling locations. The many case studies from Saudi Arabia, Oman, Qatar and the United Arab Emirates, which are reviewed in this paper, attest to the effectiveness of 3D seismology in exploration and producing, in clastics and carbonates reservoirs, and in the Mesozoic and Paleozoic.

Stable magnetic fields in stellar interiors  

E-Print Network [OSTI]

We investigate the 50-year old hypothesis that the magnetic fields of the Ap stars are stable equilibria that have survived in these stars since their formation. With numerical simulations we find that stable magnetic field configurations indeed appear to exist under the conditions in the radiative interior of a star. Confirming a hypothesis by Prendergast (1956), the configurations have roughly equal poloidal and toroidal field strengths. We find that tori of such twisted fields can form as remnants of the decay of an unstable random initial field. In agreement with observations, the appearance at the surface is an approximate dipole with smaller contributions from higher multipoles, and the surface field strength can increase with the age of the star. The results of this paper were summarised by Braithwaite & Spruit (2004).

The Gulf War and the environment  

SciTech Connect (OSTI)

The Gulf War inflicted dramatic environmental damage upon the fragile desert and shore environments of Kuwait and northeastern Saudi Arabia. Coastal and marine environments experienced oil spills of more than 8 million barrels, which killed wildlife and damaged the fishing industry. In inland Kuwait, hundreds of oil lakes are scattered across the desert surface: these lakes emit noxious gases, drown insects and birds, and may seep to pollute groundwater. Exploding and burning oil wells released soot particles, oil droplets, and noxious chemicals into the atmosphere, spreading air pollution, acid rain, and respiratory problems. Military diggings, constructions, and vehicles have destroyed much of the desert pavement, resulting in increased dust storms and large, moving dunes.

Nuclear winter from gulf war discounted  

SciTech Connect (OSTI)

Would a major conflagration in Kuwait's oil fields trigger a climate catastrophe akin to the 'nuclear winter' that got so much attention in the 1980s This question prompted a variety of opinions. The British Meteorological Office and researchers at Lawrence Livermore National Laboratory concluded that the effect of smoke from major oil fires in Kuwait on global temperatures is likely to be small; however, the obscuration of sunlight might significantly reduce surface temperatures locally. Michael MacCracken, leader of the researchers at Livermore, predicts that the worst plausible oil fires in the Gulf would produce a cloud of pollution about as severe as that found on a bad day at the Los Angeles airport. The results of some mathematical modeling by the Livermore research group are reported.

Behavior of chars from Bursa Mustafa Kemal Pasa Alpagut and Balkesir Dursunbey Cakiirca Lignite (Turkey) during non-catalytic and catalytic gasification  

SciTech Connect (OSTI)

The reactivities of chars obtained by pyrolysis of Bursa Mustafa Kemal Pasa Alpagut lignite and Balkesir Dursunbey Cakiirca lignite (Turkey) at different temperatures were determined by CO{sub 2} gasification and by combustion with O{sub 2}. Catalytic effect of Na{sub 2}CO{sub 3} on the CO{sub 2} and O{sub 2} gasification reactivity of chars was investigated. Gasification tests were performed in the fixed bed reactors operating at ambient pressure. Reactivity of chars during the CO{sub 2} gasification reactions was determined by calculating the reaction rate constants and reactivity of chars during the O{sub 2} gasification was determined by using ignition temperatures of the samples. Activation energies and Arrhenius constants of the chars on the CO{sub 2} gasification reactions were also calculated by the help of Arrhenius curves. The activation energy for CO{sub 2} gasification was generally decreased with pyrolysis temperature, due to the different surface characteristics and different nature of carbon atoms gasified as the gasification reactions proceed. Generally, the increase in pyrolysis temperature leads to an increase in gasification reactivity with CO{sub 2}. The reactivity of chars in catalytic gasification was higher than the corresponding non-catalytic reactivity of the same chars. Ignition temperature increased with increasing pyrolysis temperature.

SUPPORT OF GULF OF MEXICO HYDRATE RESEARCH CONSORTIUM: ACTIVITIES TO SUPPORT ESTABLISHMENT OF A SEA FLOOR MONITORING STATION PROJECT  

SciTech Connect (OSTI)

The Gulf of Mexico Hydrates Research Consortium (GOM-HRC) was established in 1999 to assemble leaders in gas hydrates research. The Consortium is administered by the Center for Marine Resources and Environmental Technology, CMRET, at the University of Mississippi. The primary objective of the group is to design and emplace a remote monitoring station or sea floor observatory (MS/SFO) on the sea floor in the northern Gulf of Mexico by the year 2007, in an area where gas hydrates are known to be present at, or just below, the sea floor. This mission, although unavoidably delayed by hurricanes and other disturbances, necessitates assembling a station that will monitor physical and chemical parameters of the marine environment, including sea water and sea-floor sediments, on a more-or-less continuous basis over an extended period of time. In 2005, biological monitoring, as a means of assessing environmental health was added to the mission of the MS/SFO. Establishment of the Consortium has succeeded in fulfilling the critical need to coordinate activities, avoid redundancies and communicate effectively among researchers in the arena of gas hydrates research. Complementary expertise, both scientific and technical, has been assembled to promote innovative research methods and construct necessary instrumentation. The observatory has now achieved a microbial dimension in addition to the geophysical and geochemical components it had already included. Initial components of the observatory, a probe that collects pore-fluid samples and another that records sea floor temperatures, were deployed in Mississippi Canyon 118 in May of 2005. Follow-up deployments, planned for fall 2005, had to be postponed due to the catastrophic effects of Hurricane Katrina (and later, Rita) on the Gulf Coast. Every effort was made to locate and retain the services of a suitable vessel and submersibles or Remotely Operated Vehicles (ROVs) following the storms and the loss of the contracted vessel, the M/V Ocean Quest and its two submersibles, but these efforts have been fruitless due to the demand for these resources in the tremendous recovery effort being made in the Gulf area. Station/observatory completion, anticipated for 2007, will likely be delayed by at least one year. The seafloor monitoring station/observatory is funded approximately equally by three federal Agencies: Minerals Management Services (MMS) of the Department of the Interior (DOI), National Energy Technology Laboratory (NETL) of the Department of Energy (DOE), and the National Institute for Undersea Science and Technology (NIUST), an agency of the National Oceanographic and Atmospheric Administration (NOAA).

Methane generation at Grand Gulf Nuclear Station  

SciTech Connect (OSTI)

The methane generation at Grand Gulf has been brought to light twice. The initial event occurred in February 1990 and the second in December 1993. Both events involved the receipt of a cask at Barnwell Waste Management Facility that when opened indicated a gas escaping. The gas was subsequently sampled and indicated a percentage of explosive gas. Both events involved powdered resin and indicated that the generation was from a bacterial attack of the organic materials (cellulose in the powdered resin mixture). The first event occurred and was believed to be isolated in a particular waste stream. The situation was handled and a biocide was found to be effective in treatment of liners until severe cross contamination of another waste stream occurred. This allowed the shipment of a liner that was required to be sampled for explosive gases. The biocide used by GGNS was allowed reintroduction into the floor drains and this allowed the buildup of immunity of the bacterial population to this particular biocide. The approval of a new biocide has currently allowed GGNS to treat liners and ship them offsite.

Arms and oil: US military strategy and the Persian Gulf  

SciTech Connect (OSTI)

In the oil-rich Persian Gulf, a region crucial to the world's security and economic health, the United States confronts major challenges to its military and diplomatic skills. The Iranian revolution, the Soviet invasion of Afghanistan, and unpredictable turbulence have contributed to declining US influence in the area. In the United States, military questions about force size and strategy have sparked controversy over the proper US role in the Gulf. In this book Thomas L. McNaugher offers a military strategy for the Gulf that seeks to balance the risks of overinvolvement against the risks of neglect. The author, a research associate in the Brookings Foreign Policy Studies program, believes that the United States must cultivate the traditional security mechanisms of the states on the Arabian Peninsula, and he encourages cooperation with allies like Great Britain and France that historically have been involved in Gulf security. He argues that the United States should focus on protecting the Gulf states from external attack and on deterring further Soviet encroachment in the region, leaving internal security largely to the states themselves. 19 figs., 13 tabs.

Red River play, Gulf Canada deal boost Williston basin  

SciTech Connect (OSTI)

High levels of activity in the Williston basin are assured this year with an expanding horizontal drilling play for oil in Ordovician Red River. The Red River play, like the Mississippian Lodgepole mound play, is centered in North Dakota. But the Red River play is much larger, extending into eastern Montana and northwestern South Dakota. More than 500 Red River B wells have been staked. One of the most recent companies to position itself in both plays is Gulf Canada Resources Ltd. The company forged an agreement with the Assiniboine and Sioux Indian tribes. The agreement initially provides Gulf access to about 800,000 acres on the Fort Peck Indian Reservation, mostly in Roosevelt County, Mont., on the western slope of the Williston basin. Under an option, Gulf`s access could later expand to cover the reservation`s remaining 1.3 million acres. The paper discusses the extent of the Red River play, and Gulf Canada`s role in its development.

Hydrogeological influences on petroleum accumulations in the Arabian Gulf  

SciTech Connect (OSTI)

The stratigraphic and topographic conditions in the Arabian Gulf are appropriate for the instigation and maintenance of an active hydrodynamic regime. The setting is that of a gentle basin surrounded by topographic highs. The central Arabian highlands to the west-southwest, the Tarus-Zagros mountains to the north, and the Oman mountains to the east rim the structural low occupied by the Gulf. Elevations in these areas reach maximum values of approximately 1000 meters. Paleozoic through Cenozoic strata stretch continuously across the basin, are relatively unfaulted, and outcrop in the topographic highs. Such a setting is propitious for a regional hydrodynamic system with meteoric recharge in the topographic highs and discharge in the middle of the Gulf. The prolific oil and gas accumulations of this region would be subject to influence by these hydrodynamic processes. The existence of such a hydrodynamic regime is documented by a variety of evidence, including potentiometric data, water salinity measurements, and observed tilts in oil-water contacts. Potentiometric data for several Tertiary and Cretaceous units on the Arabian platform, in the Gulf, and in Iraq show a pattern of consistently decreasing potential from topographic highs to lows. Water salinities show a consistent, but inverse, variation with the potentiometric data. Tilted oil-water contacts in Cretaceous and Jurassic reservoirs are observed in several fields of the Gulf region. The direction and magnitude of the observed tilts are consistent with the water potential and salinity data, and suggest that petroleum accumulations are being influenced by a regional hydrodynamic drive. Basin modelling is used to simulate petroleum generation and migration scenarios, and to integrate these histories with the structural evolution of the Gulf. The integrated modelling study illustrates the influence of hydrodynamic processes on the distribution of petroleum accumulations.

LIGNITE FUEL ENHANCEMENT  

SciTech Connect (OSTI)

The Design Team continued to conference this quarter. Their primary task during this timeframe was to finalize the dryer design based on information learned from the NDIC Pilot work and detailed design discussions at Barr offices in August. Heyl-Patterson was tasked with incorporating all comments and drafting drawings. They submitted a preliminary proposal which spawned detailed discussions about tube bundle, air locks, and fire suppression systems. The type of fire protection specified dictated the final structural arrangement. Three meetings were spent discussing the pro's and con's of suppression vs. ventilation systems. In the end, the dryer and bucket elevator will have suppression systems and the remaining equipment will be explosion vented. This is in agreement with GRE's current insurer, FM Global. Three inlet airlocks were reduced to two and four outlets were reduced to three. The inlet plenum was subdivided for greater flexibility and sparging air added in the outlet plenum. It was also decided to use bundles with varied material, diameter, and tube & fin spacing. This will be completed in an effort to identify for us which configuration has the best heat transfer characteristics using coal as the fluidizing medium. The dryer will also be delivered in four pieces. This will allow for installation through the current access door on the Air Heater deck. The Input/Output list and functional description was completed and forwarded to Honeywell to finalize controls. Major pieces of equipment received this quarter were the Bucket Elevator, Liewell Screen, conveyors, and Motor Control Center. ICI completed removal of the wall separating Silo 28 from the dryer area; handrail and grating between the two areas has also been removed. They relocated a blowdown line. They moved an Air Heater basket access hatch.

Solar aided power generation of a 300 MW lignite fired power plant combined with line-focus parabolic trough collectors field  

Science Journals Connector (OSTI)

Abstract Nowadays, conventional coal or gas fired power plants are the dominant way to generate electricity in the world. In recent years there is a growth in the field of renewable energy sources in order to avoid the threat of climate change from fossil fuel combustion. Solar energy, as an environmental friendly energy source, may be the answer to the reduction of global CO2 emissions. This paper presents the concept of Solar Aided Power Generation (SAPG), a combination of renewable and conventional energy sources technologies. The operation of the 300 MW lignite fired power plant of Ptolemais integrated with a solar field of parabolic trough collectors was simulated using TRNSYS software in both power boosting and fuel saving modes. The power plant performance, power output variation, fuel consumption and CO2 emissions were calculated. Furthermore, an economic analysis was carried out for both power boosting and fuel saving modes of operation and optimum solar contribution was estimated.

Protecting steel in concrete in the Persian Gulf  

SciTech Connect (OSTI)

The climate and geomorphology of the Persian Gulf make it one of the world's most severe environments for reinforced concrete. The concrete mix ingredients are usually contaminated with chloride, and the environment around reinforced concrete structures also contains salts, both under- and above-ground. Prevailing high temperatures also promote rapid rates of corrosion. Fusion-bonded epoxy-coated rebar, polyvinyl butyral-based coated rebar, calcium nitrile corrosion-inhibiting admixture, and microsilica are reviewed as corrosion prevention measures for steel in concrete for Persian Gulf service. Detrimental effects and user-friendliness are discussed.

The Sun's interior structure and dynamics, and the solar cycle  

E-Print Network [OSTI]

The Sun's internal structure and dynamics can be studied with helioseismology, which uses the Sun's natural acoustic oscillations to build up a profile of the solar interior. We discuss how solar acoustic oscillations are affected by the Sun's magnetic field. Careful observations of these effects can be inverted to determine the variations in the structure and dynamics of the Sun's interior as the solar cycle progresses. Observed variations in the structure and dynamics can then be used to inform models of the solar dynamo, which are crucial to our understanding of how the Sun's magnetic field is generated and maintained.

The Solar Heavy Element Abundances: I. Constraints from Stellar Interiors  

E-Print Network [OSTI]

The latest solar atmosphere models include non-LTE corrections and 3D hydrodynamic convection simulations. These models predict a significant reduction in the solar metal abundance, which leads to a serious conflict between helioseismic data and the predictions of solar interiors models. We demonstrate that the helioseismic constraints on the surface convection zone depth and helium abundance combined with stellar interiors models can be used to define the goodness of fit for a given chemical composition. After a detailed examination of the errors in the theoretical models we conclude that models constructed with the older solar abundances are consistent (solar abundance scale are discussed.

Lee, and Robert D. Clear Call Number LBNL-4417E Abstract The objective of this study was to explore how calibrated high dynamic range (HDR) images (luminance maps) acquired in real world daylit environments can be used to characterize, evaluate, and compare visual comfort conditions of innovative facade shading and light-redirecting systems. Detailed (1536 x 1536 pixel) luminance maps were time-lapse acquired from two view positions in an unoccupied full scale testbed facility. These maps were analyzed using existing visual comfort metrics to quantify how innovative interior and exterior shading systems compare to conventional systems under real sun and sky conditions over a solstice-to-solstice test interval. The results provide a case study in the challenges and potential of methods of visualizing, evaluating and summarizing daily and seasonal variation of visual comfort conditions computed from large sets of image data.

An environment friendly and efficient lignite-fired power generation process based on a boiler with an open pulverizing system and the recovery of water from mill-exhaust  

Science Journals Connector (OSTI)

Abstract This paper advances a novel lignite-fired power generation process based on a OPSB (boiler with an open pulverizing system) and the recovery of water from mill-exhaust after the comprehensive analysis of the open pulverizing system used for high-moisture coals and heat/water recovery from boiler exhaust. Then, the thermal calculation method that applies to OPSB is presented based on heat and mass balance analyses of the boiler. Finally, an efficient unit applying the OPSB process is compared with a conventional 600 MW lignite-fired power unit, and the performance of the efficient unit is calculated and discussed in detail. The results show that the efficient unit not only yields a notable increase in the boiler's (2.6%) and the power plant's (1.3%) thermal efficiency but also provides a remarkable advantage in water recovery due to the mass of water vapor concentrated in mill-exhaust. In the efficient unit, the volume fraction of water vapor in mill-exhaust reaches 34%, the water reclaimed from mill-exhaust is so much that a lignite-fired power plant with zero water consumption can be expected, while the pollutant emissions can be reduced in proportion to the increase in boiler thermal efficiency.

Measure Guideline: Summary of Interior Ducts in New Construction, Including an Efficient, Affordable Method to Install Fur-Down Interior Ducts  

SciTech Connect (OSTI)

This document illustrates guidelines for the efficient installation of interior duct systems in new housing, including the fur-up chase method, the fur-down chase method, and interior ducts positioned in sealed attics or sealed crawl spaces. This document illustrates guidelines for the efficient installation of interior duct systems in new housing. Interior ducts result from bringing the duct work inside a home's thermal and air barrier. Architects, designers, builders, and new home buyers should thoroughly investigate any opportunity for energy savings that is as easy to implement during construction, such as the opportunity to construct interior duct work. In addition to enhanced energy efficiency, interior ductwork results in other important advantages, such as improved indoor air quality, increased system durability and increased homeowner comfort. While the advantages of well-designed and constructed interior duct systems are recognized, the implementation of this approach has not gained a significant market acceptance. This guideline describes a variety of methods to create interior ducts including the fur-up chase method, the fur-down chase method, and interior ducts positioned in sealed attics or sealed crawl spaces. As communication of the intent of an interior duct system, and collaboration on its construction are paramount to success, this guideline details the critical design, planning, construction, inspection, and verification steps that must be taken. Involved in this process are individuals from the design team; sales/marketing team; and mechanical, insulation, plumbing, electrical, framing, drywall and solar contractors.

Polynuclear aromatic hydrocarbons (PAHs) in fish from the Arabian Gulf  

SciTech Connect (OSTI)

Emphasis has been placed upon the identification and qualification of compounds with potential adverse health effects on humans. Prominent among this group are polynuclear aromatic hydrocarbons (PAHs), several of which are known or suspected carcinogens. PAHs enter the marine environment from a variety of sources including petroleum pollution, industrial and domestic effluents, atmospheric particles, and biosynthesis by plants and microorganisms. Although one-third of the world's oil is produced around the Arabian Gulf, no detailed analysis have been conducted to determine PAHs in this region. Nevertheless, numerous investigations have shown the ability of marine organisms including fish to accumulation PAHs from solution or dispersion in seawater. When fish are harvested, a human health hazard may result. In the present communication, high performance liquid chromatography (HPLC) was used to identify and measure sixteen PAHs priority pollutants issued by US Environmental Protection Agency (EPA) in fourteen species of commercially significant fish from the NW Arabian Gulf.

Chemical arms not cause of Gulf War syndrome  

SciTech Connect (OSTI)

A task force commissioned by the Pentagon's Defense Science Board has found no evidence that US troops were exposed to chemical or biological weapons or to any other environmental hazard during the Persian gulf War that could resolve the mystery of unexplained symptoms now dubbed the Gulf War Syndrome.'' A Czech chemical weapons monitoring team reported detecting the nerve gas sarin and sulfur mustard at two sites in Saudi Arabia near the Iraqi border in mid-January 1991. Despite the Pentagon's uncertainties about the Czech reports, many US soldiers believe they were exposed to low levels of chemical agents. They are not convinced that all of the many chemical sensor alarms that went off during the air war were false alarms.

Three-dimensional numerical modeling of thermohaline and wind-driven circulations in the Persian Gulf  

Science Journals Connector (OSTI)

The Persian Gulf circulation is investigated with respect to the relevant forcing mechanism including wind stress and thermohaline surface fluxes by using a three-dimensional numerical hydrodynamic model. The model results show a correlation between the strength of the bottom layer outflow of the Persian Gulf and that of the Indian Ocean Surface Water (IOSW) inflow into the Gulf. The inflow of IOSW into the Gulf attain maximum values in May–June in conjunction with peak bottom outflow through the Hormuz Strait. The results of sensitivity experiment indicate that circulation is dominated by thermohaline flows at almost all parts of the Gulf. The heat fluxes play an essential role on the general circulation of the Persian Gulf. In spring and summer, the wind stress generates southeast-flowing surface currents of magnitude about 5 cm/s along the Saudi Arabia and Iranian coasts on the northern Gulf. In winter and autumn, due to weak static stability, the wind produces mesoscale eddies in most parts of the Gulf. In winter and spring the wind stress acts to reinforce the thermohaline circulation of deep outflow. Conversely, in summer and autumn the wind forcing acts in opposition to the thermohaline forcing and causes a bottom inflow from Oman Sea into the Gulf.

Biggest oil spill tackled in gulf amid war, soft market  

SciTech Connect (OSTI)

Industry is scrambling to cope with history's biggest oil spill against the backdrop of a Persian Gulf war and a softening oil market. U.S. and Saudi Arabian officials accused Iraq of unleashing an oil spill of about 11 million bbl into the Persian Gulf off Kuwait last week by releasing crude from the giant Sea Island tanker loading terminal at Mina al Ahmadi. Smart bombs delivered by U.S. aircraft hit two onshore tank farm manifold stations, cutting off the terminal's source of oil flow Jan. 26. A small volume of oil was still leaking from 13 mile feeder pipelines to the terminal at presstime. Press reports quoted U.S. military and Saudi officials as estimating the slick at 35 miles long and 10 miles wide but breaking up in some areas late last week. Meantime, Iraq reportedly opened the valves at its Mina al Bakr marine terminal at Fao to spill crude into the northern gulf. BBC reported significant volumes of crude in the water off Fao 24 hr after the terminal valves were opened. Mina al Bakr is a considerably smaller terminal than Sea Island, suggesting that the resulting flow of oil would be smaller than that at Sea Island.

Efficiency and power upgrade by an additional high pressure economizer installation at an aged 620 MWe lignite-fired power plant  

Science Journals Connector (OSTI)

Abstract An additional high pressure economizer was installed at Unit B1 of the 620 MWe lignite-fired Power Plant “Nikola Tesla B” after 30 years of its operation. An innovative connection of the new additional economizer was applied. It is in parallel connection to the first section of the originally built economizer and it is directly fed with the feedwater from the outlet of the feedwater pump. The analysis of Unit B1 operation with such an economizer arrangement is performed and it is supported by measured data. It is shown that more than 30 MWth of the flue gas waste heat is recovered. The Unit gross efficiency is increased by 0.53 percentage points, which leads to 9.4 MWe of the electric power production. The parallel connection of the additional economizer also leads to the partial feedwater bypass of the high pressure heaters, which enables an increase of the plant electric power by up to 24.5 MWe. The accompanying effects are the reduction of the pressure drop in the feedwater line and the economizers, which leads to the decrease of the energy consumption for the main feedwater pump operation. The applied solution is presented together with measured and calculated energy and economic benefits.

OHMIC DISSIPATION IN THE INTERIORS OF HOT JUPITERS  

SciTech Connect (OSTI)

We present models of ohmic heating in the interiors of hot Jupiters in which we decouple the interior and the wind zone by replacing the wind zone with a boundary temperature T{sub iso} and magnetic field B{sub {phi}0}. Ohmic heating influences the contraction of gas giants in two ways: by direct heating within the convection zone and by heating outside the convection zone, which increases the effective insulation of the interior. We calculate these effects and show that internal ohmic heating is only able to slow the contraction rate of a cooling gas giant once the planet reaches a critical value of internal entropy. We determine the age of the gas giant when ohmic heating becomes important as a function of mass, T{sub iso}, and induced B{sub {phi}0}. With this survey of parameter space complete, we then adopt the wind zone scalings of Menou and calculate the expected evolution of gas giants with different levels of irradiation. We find that, with this prescription of magnetic drag, it is difficult to inflate massive planets or those with strong irradiation using ohmic heating, meaning that we are unable to account for many of the observed hot Jupiter radii. This is in contrast to previous evolutionary models that assumed that a constant fraction of the irradiation is transformed into ohmic power.

SUPPORT OF GULF OF MEXICO HYDRATE RESEARCH CONSORTIUM: ACTIVITIES TO SUPPORT ESTABLISHMENT OF A SEA FLOOR MONITORING STATION PROJECT  

SciTech Connect (OSTI)

The Gulf of Mexico Hydrates Research Consortium (GOM-HRC) was established in 1999 to assemble leaders in gas hydrates research. The primary objective of the group has been to design and emplace a remote monitoring station or sea floor observatory (MS/SFO) on the sea floor in the northern Gulf of Mexico by the year 2005, in an area where gas hydrates are known to be present at, or just below, the sea floor. This mission, although unavoidably delayed by hurricanes and other disturbances, necessitates assembling a station that will monitor physical and chemical parameters of the sea water and sea floor sediments on a more-or-less continuous basis over an extended period of time. Development of the station has always included the possibility of expanding its capabilities to include biological monitoring, as a means of assessing environmental health. This possibility has recently achieved reality via the National Institute for Undersea Science and Technology's (NIUST) solicitation for proposals for research to be conducted at the MS/SFO. Establishment of the Consortium has succeeded in fulfilling the critical need to coordinate activities, avoid redundancies and communicate effectively among researchers in the arena of gas hydrates research. Complementary expertise, both scientific and technical, has been assembled to promote innovative research methods and construct necessary instrumentation. The observatory has achieved a microbial dimension in addition to the geophysical and geochemical components it had already included. Initial components of the observatory, a probe that collects pore-fluid samples and another that records sea floor temperatures, were deployed in Mississippi Canyon 118 in May of 2005. Follow-up deployments, planned for fall 2005, have had to be postponed and the use of the vessel M/V Ocean Quest and its two manned submersibles sacrificed due to the catastrophic effects of Hurricane Katrina (and later, Rita) on the Gulf Coast. Every effort is being made to locate and retain the services of a replacement vessel and submersibles or Remotely Operated Vehicles (ROVs) but these efforts have been fruitless due to the demand for these resources in the tremendous recovery effort being made in the Gulf area. Station/observatory completion, anticipated for 2007, will likely be delayed by at least one year. The seafloor monitoring station/observatory is funded approximately equally by three federal Agencies: Minerals Management Services (MMS) of the Department of the Interior (DOI), National Energy Technology Laboratory (NETL) of the Department of Energy (DOE), and the National Institute for Undersea Science and Technology (NIUST), an agency of the National Oceanographic and Atmospheric Administration (NOAA). Subcontractors with FY03 funding fulfilled their technical reporting requirements in the previous report (41628R10). Only unresolved matching funds issues remain and will be addressed in the report of the University of Mississippi's Office of Research and Sponsored Programs.

In other words, we consider a black hole which has grown up from a small one in the heat bath adiabatically. We express the metric of the interior of the black hole in terms of two functions: One is the intensity of the Hawking radiation, and the other is the ratio between the radiation energy and the pressure in the radial direction. Especially in the case of conformal matters we check that it is a self-consistent solution of the semi-classical Einstein equation, $G_{\\mu\

Measurement of gas species, temperatures, coal burnout, and wall heat fluxes in a 200 MWe lignite-fired boiler with different overfire air damper openings  

SciTech Connect (OSTI)

Measurements were performed on a 200 MWe, wall-fired, lignite utility boiler. For different overfire air (OFA) damper openings, the gas temperature, gas species concentration, coal burnout, release rates of components (C, H, and N), furnace temperature, and heat flux and boiler efficiency were measured. Cold air experiments for a single burner were conducted in the laboratory. The double-swirl flow pulverized-coal burner has two ring recirculation zones starting in the secondary air region in the burner. As the secondary air flow increases, the axial velocity of air flow increases, the maxima of radial velocity, tangential velocity and turbulence intensity all increase, and the swirl intensity of air flow and the size of recirculation zones increase slightly. In the central region of the burner, as the OFA damper opening widens, the gas temperature and CO concentration increase, while the O{sub 2} concentration, NOx concentration, coal burnout, and release rates of components (C, H, and N) decrease, and coal particles ignite earlier. In the secondary air region of the burner, the O{sub 2} concentration, NOx concentration, coal burnout, and release rates of components (C, H, and N) decrease, and the gas temperature and CO concentration vary slightly. In the sidewall region, the gas temperature, O{sub 2} concentration, and NOx concentration decrease, while the CO concentration increases and the gas temperature varies slightly. The furnace temperature and heat flux in the main burning region decrease appreciably, but increase slightly in the burnout region. The NOx emission decreases from 1203.6 mg/m{sup 3} (6% O{sub 2}) for a damper opening of 0% to 511.7 mg/m{sup 3} (6% O{sub 2}) for a damper opening of 80% and the boiler efficiency decreases from 92.59 to 91.9%. 15 refs., 17 figs., 3 tabs.

Modeling of air currents in the Gulf Region

The Atmospheric Release Advisory Capability modeled the wind flow in the Gulf Region in order to make projections of the Kuwait oil fires pollution dispersion. Extensive meteorological models incorporating explicit terrain influences to the flow fields were routinely employed through a six month international assessment support effort organized by the World Meteorological Organization and US scientific research agencies. Results show generally close agreement with visible imagery of the smoke plumes as detected by meteorological satellites. However, there are some examples of significant disagreement or failure of the meteorological models. These failures are most likely directly linked to missing or unavailable weather observations.

Imaging the Earth's Interior: the Angular Distribution of Terrestrial Neutrinos  

E-Print Network [OSTI]

Decays of radionuclides throughout the Earth's interior produce geothermal heat, but also are a source of antineutrinos. The (angle-integrated) geoneutrino flux places an integral constraint on the terrestrial radionuclide distribution. In this paper, we calculate the angular distribution of geoneutrinos, which opens a window on the differential radionuclide distribution. We develop the general formalism for the neutrino angular distribution, and we present the inverse transformation which recovers the terrestrial radioisotope distribution given a measurement of the neutrino angular distribution. Thus, geoneutrinos not only allow a means to image the Earth's interior, but offering a direct measure of the radioactive Earth, both (1) revealing the Earth's inner structure as probed by radionuclides, and (2) allowing for a complete determination of the radioactive heat generation as a function of radius. We present the geoneutrino angular distribution for the favored Earth model which has been used to calculate geoneutrino flux. In this model the neutrino generation is dominated by decays in the Earth's mantle and crust; this leads to a very ``peripheral'' angular distribution, in which 2/3 of the neutrinos come from angles > 60 degrees away from the downward vertical. We note the possibility of that the Earth's core contains potassium; different geophysical predictions lead to strongly varying, and hence distinguishable, central intensities (< 30 degrees from the downward vertical). Other uncertainties in the models, and prospects for observation of the geoneutrino angular distribution, are briefly discussed. We conclude by urging the development and construction of antineutrino experiments with angular sensitivity. (Abstract abridged.)

Trace metals in gills of fish from the Arabian Gulf  

SciTech Connect (OSTI)

Complexation of metals by coordinate linkages with appropriate organic molecules in biological tissues is an important process involved in metal accumulation by aquatic organisms. Fish respiratory systems differ from all other systems because damage to gills has immediate impacts on the rest of the fish's body. Veer et al. observed significant correlation between gill-metal concentration and whole-body weight. More nickel is accumulated in gill tissue of the catfish (Clarias batrachus) than in the liver or intestine. More cadmium is accumulated in gill tissue of the fish Heteropneustes fossilis (Bloch) and Channa punctatus (Bloch) than in the liver or kidney. When exposed to lethal and sublethal concentrations of copper, gills of the freshwater fish Labeo rohita (Hamilton) showed the highest degree of copper accumulation. Petroleum and petrochemical industry wastes contribute significantly to metal enrichment of the Arabian Gulf marine environment. Because accumulation of metal ions is significant in gills, levels of Cd, Cr, Cu, Ni and Pb were investigated in gills of fish from potentially impacted areas along the western side of the Arabian Gulf after the 1991 oil-spill. 15 refs., 3 figs., 1 tab.

World tanker industry maintains momentum from Persian Gulf war  

SciTech Connect (OSTI)

The world tanker industry has managed to maintain the momentum generated during the Persian Gulf War. Freight rates for large vessels have regained the high levels seen during the first 2 months of this year, while the expected postwar decline in use of tankers has not materialized. The health of the tanker industry is linked closely with the volume of long haul crude oil from the Middle East, a spot charter from the gulf to Europe, an owner would only break even on the cost of building and operating a new tanker to the highest environmental standards. Owners currently can expect spot rates of about $40,000/day, excellent by the standards of the late 1980s and early 1990s but still below the level needed to justify new buildings. And there are many in the industry who think $40,000/day will be just a happy memory later in the year. Owners are facing pressure for major changes in the industry. Governments and the public want better operating standards and new environmentally sound tankers to reduce the risk of oil spills. At the same time, the industry has to learn to live with repercussion in the 1990 Oil Pollution Act in the U.S., which has opened the way for unlimited liability against tanker owners involved in spills off the U.S. The search also is on for improved profits to make investments required by the changing world of seaborne oil transportation.

After the oil boom: The holiday ends in the gulf  

SciTech Connect (OSTI)

The most unmanageable risk facing American interests in the Persian Gulf is the slow but sure decay of the economic and political structure of the United States` key regional allies. They are the Gulf Cooperation Council (GCC) states: Saudia Arabia, Kuwait, Bahrain, Qatar, Oman, and the United Arab Emirates (UAE). External threats to these friendly governments and the direct risks to the continued flow of oil has blinded Washington to the end of these countries 20-year holiday from politics and economics. The holiday from economics was characterized by, among other syndromes, the lack of binding budget constraints, which reduced and sometimes even eliminated the need to set spending priorities and allocate scarce economic resources. It is no longer possible to cover up structural weaknesses and policy inconsistencies. All major interest groups, including governments, ruling families, merchant families, and the population at large, are under pressure to earn not only their privileges but their keep. The need for Washington to address these new threats is examined.

Persian Gulf and the national interest. Professional paper  

SciTech Connect (OSTI)

With gasoline lines a fading memory, it is easy for Americans to misinterpret the energy crisis as overinflated, and even easier to underestimate the importance of the Persian Gulf. Yet, it was just two years ago that former President Carter designated the Persian Gulf as a region of vital national interest. His purpose, in what came to be known as the Carter Doctrine, was to help ensure the steady flow of petroleum to the world market. President Reagan has subsequently confirmed that policy by increasing the U.S. military presence in the Inidan Ocean, strengthening the Rapid Deployment Force (RDF), and selling AWACS and other advanced military equipment to Saudi Arabia. What seemed to be a sensible policy direction with the turmoil in Iran, skyrocketing oil prices, and the Soviet intervention in Afghanistan, has come under increasing criticism in the light of today's plentiful supplies of oil. A growing chorus of optimists argues that reliance on the unfettered market will give us a future of abundant energy and freedom from dependence on oil imports.

System Cost Analysis for an Interior Permanent Magnet Motor  

SciTech Connect (OSTI)

The objective of this program is to provide an assessment of the cost structure for an interior permanent magnet ('IPM') motor which is designed to meet the 2010 FreedomCAR specification. The program is to evaluate the range of viable permanent magnet materials for an IPM motor, including sintered and bonded grades of rare earth magnets. The study considers the benefits of key processing steps, alternative magnet shapes and their assembly methods into the rotor (including magnetization), and any mechanical stress or temperature limits. The motor's costs are estimated for an annual production quantity of 200,000 units, and are broken out into such major components as magnetic raw materials, processing and manufacturing. But this is essentially a feasibility study of the motor's electromagnetic design, and is not intended to include mechanical or thermal studies as would be done to work up a selected design for production.

Isentropic compression of hydrogen: Probing conditions deep in planetary interiors  

Science Journals Connector (OSTI)

We perform ab initio calculations for the equation of state of dense liquid hydrogen and deuterium using quantum molecular dynamics simulations based on finite-temperature density functional theory. This extensive data set allows us to determine specific density-temperature-pressure tracks such as the cold curve, precompressed and principal Hugoniot curves, and isentropes which are essential for the analysis and interpretation of high-pressure experiments. In this study we focus on conditions probed by recent quasi-isentropic shock compression experiments that have reached a so-far unprecedented 108-fold compression of gaseous deuterium. As these states of matter are relevant for the deep interior of Jupiter-like exoplanets we simultaneously give predictions for their isentropes.

CO2-gasification of a lignite coal in the presence of an iron-based oxygen carrier for chemical-looping combustion  

Science Journals Connector (OSTI)

Abstract Chemical-looping combustion (CLC) has the inherent property of separating the product CO2 from flue gases. Instead of air, it uses an oxygen carrier, usually in the form of a metal oxide, to provide oxygen for combustion. All techniques so far proposed for chemical looping with solid fuels involve initially the gasification of the solid fuel in order for the gaseous products to react with the oxygen carrier. Here, the rates of gasification of coal were compared when gasification was undertaken in a fluidised bed of either (i) an active Fe-based oxygen carrier used for chemical looping or (ii) inert sand. This enabled an examination of the ability of chemical looping materials to enhance the rate of gasification of solid fuels. Batch gasification and chemical-looping combustion experiments with a German lignite and its char are reported, using an electrically-heated fluidised bed reactor at temperatures from 1073 to 1223 K. The fluidising gas was CO2 in nitrogen. The kinetics of the gasification were found to be significantly faster in the presence of the oxygen carrier, especially at temperatures above 1123 K. A numerical model was developed to account for external and internal mass transfer and for the effect of the looping agent. The model also included the effects of the evolution of the pore structure at different conversions. The presence of Fe2O3 led to an increase in the rate of gasification because of the rapid oxidation of CO by the oxygen carrier to CO2. This resulted in the removal of CO and maintained a higher mole fraction of CO2 in the mixture of gas around the particle of char, i.e. within the mass transfer boundary layer surrounding the particle. This effect was most prominent at about 20% conversion when (i) the surface area for reaction was at its maximum and (ii) because of the accompanying increase in porosity and pore size, intraparticle resistance to gas mass transfer within the particle of char had fallen, compared with that in the initial particle. Excellent agreement was observed between the rates predicted by the numerical model and those observed experimentally.
