LOW COST METHODOLOGIES TO ANALYZE AND CORRECT ABNORMAL PRODUCTION DECLINE IN STRIPPER GAS WELLS

Description: A study group of 376 Clinton Sand wells in Ohio provided data to determine the historic frequency of the problem of abnormal production declines in stripper gas wells and the causes of the abnormal production decline. Analysis of the historic frequency of the problem indicates over 70% of the wells experienced abnormal production decline. The most frequently occurring causes of abnormal production declines were determined to be fluid accumulation (46%), gas gathering restrictions (24%), and mec… more

Carbon sequestration with enhanced gas recovery: Identifying candidate sites for pilot study

Description: Depleted natural gas reservoirs are promising targets for carbon dioxide sequestration. Although depleted, these reservoirs are not devoid of methane, and carbon dioxide injection may allow enhanced production of methane by reservoir repressurization or pressure maintenance. Based on the favorable results of numerous simulation studies, we propose a field test of the Carbon Sequestration with Enhanced Gas Recovery (CSEGR) process. The objective of the field test is to evaluate the feasibility o… more

METHANE de-NOX FOR UTILITY PC BOILERS

Description: The overall project objective is the development and validation of an innovative combustion system, based on a novel coal preheating concept prior to combustion, that can reduce NOx emissions to 0.15 lb/million Btu or less on utility pulverized coal (PC) boilers. This NOx reduction should be achieved without loss of boiler efficiency or operating stability, and at more than 25% lower levelized cost than state-of-the-art SCR technology. A further objective is to make this technology ready for fu… more

FRACTURED RESERVOIR E&P IN ROCKY MOUNTAIN BASINS: A 3-D RTM MODELING APPROACH

Description: Key natural gas reserves in Rocky Mountain and other U.S. basins are in reservoirs with economic producibility due to natural fractures. In this project, we evaluate a unique technology for predicting fractured reservoir location and characteristics ahead of drilling based on a 3-D basin/field simulator, Basin RTM. Recommendations are made for making Basin RTM a key element of a practical E&P strategy. A myriad of reaction, transport, and mechanical (RTM) processes underlie the creation, ce… more

GASIFICATION BASED BIOMASS CO-FIRING - PHASE I

Description: Biomass gasification offers a practical way to use this locally available fuel source for co-firing traditional large utility boilers. The gasification process converts biomass into a low Btu producer gas that can be fed directly into the boiler. This strategy of co-firing is compatible with variety of conventional boilers including natural gas fired boilers as well as pulverized coal fired and cyclone boilers. Gasification has the potential to address all problems associated with the other typ… more

EXAFS and activity studies of the poisoning effect on Cl on Pt/Al{sub 2}O{sub 3} catalysts during oxidation reactions.

Description: The effect of Cl on the activity of Pt/Al{sub 2}O{sub 3} catalysts for methane oxidation has been studied by H{sub 2} and CO chemisorption, O{sub 2} isotopic exchange, kinetic studies and EXAFS spectroscopy. Catalysts containing 1.5% pt/Al{sub 2}O{sub 3} were prepared by incipient wetness from H{sub 2}PtCl{sub 6} and Pt(NH{sub 3}){sub 4}(NO{sub 3}){sub 2} precursors. Both reduced catalysts have similar dispersion (0.8) as determined by H{sub 2} chemisorption. At low methane concentration (0.3 v… more

Hybrid Sulfur Recovery Process for Natural Gas Upgrading Quarterly Report

Description: This first quarter report of 2001 describes progress on a project funded by the U.S. Department of Energy (DOE) to test a hybrid sulfur recovery process for natural gas upgrading. The process concept represents a low cost option for direct treatment of natural gas streams to remove H{sub 2}S in quantities equivalent to 0.2-25 metric tons (LT) of sulfur per day. This process is projected to have lower capital and operating costs than the competing technologies, amine/aqueous iron liquid redox an… more

Design, Fabrication, Assembly and Bench Testing of a Texaco Infrared Ratio Pyrometer System for the Measurement of Reaction Chamber Temperature

Description: Reliable measurement of gasifier reaction chamber temperature is important for the proper operation of slagging, entrained-flow gasification processes. Historically, thermocouples have been used as the main measurement technique, with the temperature inferred from syngas methane concentration being used as a backup measurement. While these have been sufficient for plant operation in many cases, both techniques suffer from limitations. The response time of methane measurements is too slow to det… more

C{sub 2}D{sub 5}I dissociation and D + CH{sub 3} {yields} CH{sub 2}D + H at high temperature : implications to the high pressure rate constant for CH{sub 4} dissociation.

Description: The shock tube technique with H- and D-atom atomic resonance absorption spectrometry (ARAS) detection has been used to study the thermal decomposition of C{sub 2}D{sub 5}I and the reaction, CH{sub 3} + D'' CH{sub 2}D + H, (1) over the temperature ranges, 924-1370 K and 1294-1753 K, respectively. First-order rate constants for the thermal decomposition of C{sub 2}D{sub 5}I can be expressed by the Arrhenius equation, logk{sub C2D5I} = (10.397 {+-} 0.297) - (7700 {+-} 334 K)/T, giving k{sub C2D5I}… more

Assessment of well-to-wheel energy use and greenhouse gas emissions of Fischer-Tropsch diesel.

Description: The middle distillate fuel produced from natural gas (NG) via the Fischer-Tropsch (FT) process has been proposed as a motor fuel for compression-ignition (CI) engine vehicles. FT diesel could help reduce U.S. dependence on imported oil. The U.S. Department of Energy (DOE) is evaluating the designation of FT diesel as an alternative motor fuel under the 1992 Energy Policy Act (EPACT). As part of this evaluation, DOE has asked the Center for Transportation Research at Argonne National Laboratory … more

Development of Attrition Resistant Iron-Based Fischer-Tropsch Catalysts

Description: The Fischer-Tropsch (F-T) reaction provides a way of converting coal-derived synthesis gas (CO+H{sub 2}) to liquid fuels. Since the reaction is highly exothermic, one of the major problems in control of the reaction is heat removal. Recent work has shown that the use of slurry bubble column reactors (SBCRs) can largely solve this problem. The use of iron-based catalysts is attractive not only due to their low cost and ready availability, but also due to their high water-gas shift activity which… more

DOE final report: Studies on the microbial formation of methane

Description: The microbial formation of methane is carried out by methanogens which are found wherever active anaerobic degradation of organic matter occurs. We developed a procedure for reliable culture of 'Methanococus jannaschii' which yields 8 g wet weight of cells per liter of medium. To initiate a study of proteomics, this organism was grown at two levels of hydrogen partial pressure, very low (650 Pa) and high (178 kPa). When cells were exposed to hydrogen excess conditions, they possessed very low o… more
