Gas Atomization of Stainless Steel - Slow Motion  

SciTech Connect

Stainless steel liquid atomized by supersonic argon gas into a spray of droplets at ~1800şC. Atomization of metal requires high pressure gas and specialized chambers for cooling and collecting the powders without contamination. The critical step for morphological control is the impingement of the gas on the melt stream. The video is a black and white high speed video of a liquid metal stream being atomized by high pressure gas. This material was atomized at the Ames Laboratory's Materials Preparation Center http://www.mpc.ameslab.gov

Scattering of Slow Neutrons from Propane Gas  

Science Journals Connector (OSTI)

Measurements of the partial differential neutron scattering cross sections for room-temperature propane gas are reported. These measurements were made at incident energies of 0.0101, 0.0254, 0.0736, and 0.102 ev at seven scattering angles between 16.3° and 84.7° using the Materials Testing Reactor phased chopper velocity selector. The data are converted to the scattering-law presentation and compared with three theoretical calculations: (a) The ideal gas, using an effective mass obtained from an average of the mass tensors for the three types of H atoms in propane, gives poor agreement. (b) The Krieger-Nelkin approximation, which includes the effect of zero-point vibrations, gives limited agreement for energy transfer less than 0.5kBT at intermediate momentum transfers. At large momentum transfers where vibrational effects become important it underestimates the cross section. (c) A modification of the Krieger-Nelkin theory that includes the effects of single-quantum transitions from the three lowest vibrational states gives better agreement. The discrepancies still present at large momentum and energy transfers are attributed to an uncertainty in the methyl-group barrier height for the three lowest energy modes, to the harmonic oscillator approximation for these modes, and to the approximate molecular orientation averaging used in the calculation.

Gas Storage Technology Consortium  

SciTech Connect

Gas storage is a critical element in the natural gas industry. Producers, transmission and distribution companies, marketers, and end users all benefit directly from the load balancing function of storage. The unbundling process has fundamentally changed the way storage is used and valued. As an unbundled service, the value of storage is being recovered at rates that reflect its value. Moreover, the marketplace has differentiated between various types of storage services, and has increasingly rewarded flexibility, safety, and reliability. The size of the natural gas market has increased and is projected to continue to increase towards 30 trillion cubic feet (TCF) over the next 10 to 15 years. Much of this increase is projected to come from electric generation, particularly peaking units. Gas storage, particularly the flexible services that are most suited to electric loads, is critical in meeting the needs of these new markets. In order to address the gas storage needs of the natural gas industry, an industry-driven consortium was created-the Gas Storage Technology Consortium (GSTC). The objective of the GSTC is to provide a means to accomplish industry-driven research and development designed to enhance operational flexibility and deliverability of the Nation's gas storage system, and provide a cost effective, safe, and reliable supply of natural gas to meet domestic demand. This report addresses the activities for the quarterly period of July 1, 2006 to September 30, 2006. Key activities during this time period include: {lg_bullet} Subaward contracts for all 2006 GSTC projects completed; {lg_bullet} Implement a formal project mentoring process by a mentor team; {lg_bullet} Upcoming Technology Transfer meetings: {sm_bullet} Finalize agenda for the American Gas Association Fall Underground Storage Committee/GSTC Technology Transfer Meeting in San Francisco, CA. on October 4, 2006; {sm_bullet} Identify projects and finalize agenda for the Fall GSTC Technology Transfer Meeting, Pittsburgh, PA on November 8, 2006; {lg_bullet} Draft and compile an electronic newsletter, the GSTC Insider; and {lg_bullet} New members update.

Small gas turbine technology  

Science Journals Connector (OSTI)

Small Gas Turbine Technology: Small gas turbine, in the power range up to 500 kW, requires a recuperated thermodynamic cycle to achieve an electrical efficiency of about 30%. This efficiency is the optimum, which is possible for a cycle pressure ratio of about 4–1. The cycle airflow is function of the power requirement. To increase the efficiency, in view to reduce the CO2 emission, it is mandatory to develop a more efficient thermodynamic cycle. Different thermodynamic cycles were examined and the final choice was made for an Intercooled, Recuperated cycle. The advantage of this cycle, for the same final electrical efficiency of about 35%, is the smaller cycle airflow, which is the most dimensional parameter for the important components as the heat exchanger recuperator and the combustion chamber. In parallel with the thermodynamic cycle it is necessary to develop the High Speed Alternator technology, integrated on the same shaft that the gas turbine rotating components, to achieve the constant efficiency at part loads, from 50% up to 100%, by the capacity to adjust the engine speed at the required load. To satisfy the stringent requirement in pollutant emissions of \\{NOx\\} and CO, the catalytic combustion system is the most efficient and this advance technology has to be proven. The major constraints for the small gas turbine technology development are the production cost and the maintenance cost of the unit. In the power range of 0–500 kW the gas turbine technology is in competition with small reciprocating engines, which are produced in large quantity for automotive industry, at a very low production cost.

Gas Storage Technology Consortium  

SciTech Connect

The EMS Energy Institute at The Pennsylvania State University (Penn State) has managed the Gas Storage Technology Consortium (GSTC) since its inception in 2003. The GSTC infrastructure provided a means to accomplish industry-driven research and development designed to enhance the operational flexibility and deliverability of the nation's gas storage system, and provide a cost-effective, safe, and reliable supply of natural gas to meet domestic demand. The GSTC received base funding from the U.S. Department of Energy's (DOE) National Energy Technology Laboratory (NETL) Oil & Natural Gas Supply Program. The GSTC base funds were highly leveraged with industry funding for individual projects. Since its inception, the GSTC has engaged 67 members. The GSTC membership base was diverse, coming from 19 states, the District of Columbia, and Canada. The membership was comprised of natural gas storage field operators, service companies, industry consultants, industry trade organizations, and academia. The GSTC organized and hosted a total of 18 meetings since 2003. Of these, 8 meetings were held to review, discuss, and select proposals submitted for funding consideration. The GSTC reviewed a total of 75 proposals and committed co-funding to support 31 industry-driven projects. The GSTC committed co-funding to 41.3% of the proposals that it received and reviewed. The 31 projects had a total project value of $6,203,071 of which the GSTC committed $3,205,978 in co-funding. The committed GSTC project funding represented an average program cost share of 51.7%. Project applicants provided an average program cost share of 48.3%. In addition to the GSTC co-funding, the consortium provided the domestic natural gas storage industry with a technology transfer and outreach infrastructure. The technology transfer and outreach were conducted by having project mentoring teams and a GSTC website, and by working closely with the Pipeline Research Council International (PRCI) to jointly host technology transfer meetings and occasional field excursions. A total of 15 technology transfer/strategic planning workshops were held.

Options for Gas-to-Liquids Technology in Alaska  

SciTech Connect

The purposes of this work was to assess the effect of applying new technology to the economics of a proposed natural gas-to-liquids (GTL) plant, to evaluate the potential of a slower-paced, staged deployment of GTL technology, and to evaluate the effect of GTL placement of economics. Five scenarios were economically evaluated and compared: a no-major-gas-sales scenario, a gas-pipeline/LNG scenario, a fast-paced GTL development scenario, a slow-paced GTL development scenario, and a scenario which places the GTL plant in lower Alaska, instead of on the North Slope. Evaluations were completed using an after-tax discounted cash flow analysis. Results indicate that the slow-paced GTL scenario is the only one with a rate of return greater than 10 percent. The slow-paced GTL development would allow cost saving on subsequent expansions. These assumed savings, along with the lowering of the transportation tariff, combine to distinquish this option for marketing the North Slope gas from the other scenarios. Critical variables that need further consideration include the GTL plant cost, the GTL product premium, and operating and maintenance costs.

Natural gas pipeline technology overview.  

SciTech Connect

The United States relies on natural gas for one-quarter of its energy needs. In 2001 alone, the nation consumed 21.5 trillion cubic feet of natural gas. A large portion of natural gas pipeline capacity within the United States is directed from major production areas in Texas and Louisiana, Wyoming, and other states to markets in the western, eastern, and midwestern regions of the country. In the past 10 years, increasing levels of gas from Canada have also been brought into these markets (EIA 2007). The United States has several major natural gas production basins and an extensive natural gas pipeline network, with almost 95% of U.S. natural gas imports coming from Canada. At present, the gas pipeline infrastructure is more developed between Canada and the United States than between Mexico and the United States. Gas flows from Canada to the United States through several major pipelines feeding U.S. markets in the Midwest, Northeast, Pacific Northwest, and California. Some key examples are the Alliance Pipeline, the Northern Border Pipeline, the Maritimes & Northeast Pipeline, the TransCanada Pipeline System, and Westcoast Energy pipelines. Major connections join Texas and northeastern Mexico, with additional connections to Arizona and between California and Baja California, Mexico (INGAA 2007). Of the natural gas consumed in the United States, 85% is produced domestically. Figure 1.1-1 shows the complex North American natural gas network. The pipeline transmission system--the 'interstate highway' for natural gas--consists of 180,000 miles of high-strength steel pipe varying in diameter, normally between 30 and 36 inches in diameter. The primary function of the transmission pipeline company is to move huge amounts of natural gas thousands of miles from producing regions to local natural gas utility delivery points. These delivery points, called 'city gate stations', are usually owned by distribution companies, although some are owned by transmission companies. Compressor stations at required distances boost the pressure that is lost through friction as the gas moves through the steel pipes (EPA 2000). The natural gas system is generally described in terms of production, processing and purification, transmission and storage, and distribution (NaturalGas.org 2004b). Figure 1.1-2 shows a schematic of the system through transmission. This report focuses on the transmission pipeline, compressor stations, and city gates.

Natural Gas Research Natural Gas Research Natural gas offers tremendous opportunities for reducing the use of petroleum in transportation. Medium and heavy-duty fleets, which have significant potential to use natural gas, currently consume more than a third of the petroleum in transportation in the U.S. Natural gas is an excellent fit for a wide range of heavy-duty applications, especially transit buses, refuse haulers, and Class 8 long-haul or delivery trucks. In addition, natural gas can be a very good choice for light-duty vehicle fleets with central refueling. See the Alternative Fuels Data Center for a description of the uses and benefits of natural gas vehicles or its Laws and Incentives database for information on tax incentives.

Lithium bromide chiller technology in gas processing  

SciTech Connect

Lithium Bromide (LiBr) Absorption Chillers have been in use for more than half a century, mainly in the commercial air conditioning industry. The Gas Research Institute and EnMark Natural Gas Company co-funded a field test to determine the viability of this commercial air conditioning technology in the gas industry. In 1991, a 10 MMCFC natural gas conditioning plant was constructed in Sherman, Texas. The plant was designed to use a standard, off-the-shelf chiller from Trane with a modified control scheme to maintain tight operating temperature parameters. The main objective was to obtain a 40 F dewpoint natural gas stream to meet pipeline sales specifications. Various testing performed over the past three years has proven that the chiller can be operated economically and on a continuous basis in an oilfield environment with minimal operation and maintenance costs. This paper will discuss how a LiBr absorption chiller operates, how the conditioning plant performed during testing, and what potential applications are available for LiBr chiller technology.

Offshore oil and gas: global resource knowledge and technological change  

Science Journals Connector (OSTI)

It is argued that the contribution of technological change to the offshore oil and gas industry's progress is under-researched. As a prelude this theme, the changing geography of known offshore oil and gas resources is reviewed. Significant, and largely technologically dependent, developments are identified in terms of the industry's global spread, its extension into deep and ultradeep waters and its ability to enhance output from well-established oil and gas provinces. Three sections (on the evolution of exploration and production rigs, drilling techniques and the application of IT to improve resource knowledge and access) then examine the relationships between technological change and the offshore industry's progress. It is concluded that new technologies improve knowledge of, and access to, resources via four distinctive routes, but that the full impact of R & D is frequently related to the inter-dependence of technologies. Opportunities for further research are identified.

An overview of current and future sustainable gas turbine technologies  

Science Journals Connector (OSTI)

In this work an overview of current and future sustainable gas turbine technologies is presented. In particular, the various gas turbine technologies are described and compared. Emphasis has been given to the various advance cycles involving heat recovery from the gas turbine exhaust, such as, the gas to gas recuperation cycle, the combined cycle, the chemical recuperation cycle, the Cheng cycle, the humid air turbine cycle, etc. The thermodynamic characteristics of the various cycles are considered in order to establish their relative importance to future power generation markets. The combined cycle technology is now well established and offers superior to any of the competing gas turbine based systems, which are likely to be available in the medium term for large-scale power generation applications. In small-scale generation, less than 50 MWe, it is more cost effective to install a less complex power plant, due to the adverse effect of the economics of scale. Combined cycle plants in this power output range normally have higher specific investment costs and lower electrical efficiencies but also offer robust and reliable performance. Mixed air steam turbines (MAST) technologies are among the possible ways to improve the performance of gas turbine based power plants at feasible costs (e.g. peak load gas turbine plants).

Features of hydrotreating catalytic cracking feed and heavy slow coking gas oils  

SciTech Connect

A possible means of more extensive processing of crude oil is the use, in catalytic cracking, of heavy coking gas oils (HCGOs), a feature of which is a higher content of polycyclic aromatic compounds and resins by comparison with straight-run vacuum distillates. The presence of these compounds in catalytic cracking feed causes a reduction in the product yield and increased coke formation. Therefore, one of the problems of hydrotreating feedstock of this kind is the hydrogenation of polycyclic arenes. Processes of extensive desulphurization and denitration occur in parallel, since the sulphur and nitrogen compounds of HCGO are chiefly condensed benzoderivatives of thiophene, pyridine and carbazole, and largely concentrated in heavy aromatic and resinous fractions. The composition of the saturated part of the cracking feed plays a large role in achieving the optimum yields of gaseous and gasoline fractions. Thus an increase in the proportion of cyclanes in the feed raises the gasoline yield. In this way, an investigation of the hydrocarbon conversions during the hydrotreatment of cracking feed is of great importance. The present paper sets out the results for studying the change in the group-structural characteristics of the hydrogenation products of a mixture containing 30% HCGOs according to data of {sup 1}H and {sup 13}C NMR spectroscopy. 7 refs., 7 figs., 1 tab.

2, 2011 2, 2011 DOE's Early Investment in Shale Gas Technology Producing Results Today Washington, DC - A $92 million research investment in the 1970s by the U.S. Department of Energy (DOE) is today being credited with technological contributions that have stimulated development of domestic natural gas from shales. The result: more U.S. jobs, increased energy security, and higher revenues for states and the Federal Government. Spurred by the technological advancements resulting from this investment, U.S. shale gas production continues to grow, amounting to more than 8 billion cubic feet per day, or about 14 percent of the total volume of dry natural gas produced in the United States. DOE's Energy Information Administration (EIA) projects that the shale gas share of U.S. natural gas production will reach 45 percent by 2035. The EIA also projects that 827 trillion cubic feet of natural gas is now recoverable from U.S. shales using currently available technology-an increase of nearly 500 trillion cubic feet over earlier estimates.

Externally fired gas turbine technology: A review  

Science Journals Connector (OSTI)

Abstract Externally fired heat engines were used widely since helium the industrial revolution using dirty solid fuels for example coal, due to the lack of refined fuels. However, with the availability of clean fuels, external firing mode was abandoned, except for steam power plants. Lately, with the global trend moving towards green power production, the idea of the external fired system has captured the attention again especially externally fired gas turbine (EFGT) due to its wider range of power generation and the potential of using environment friendly renewable energy sources like biomass. In this paper, a wide range of thermal power sources utilizing EFGT such as concentrated solar power (CSP), fossil, nuclear and biomass fuels are reviewed. Gas turbine as the main component of EFGT is investigated from micro scale below 1 MWe to the large scale central power generation. Moreover, the different high temperature heat exchanger (HTHE) materials and designs are reviewed. Finally, the methods of improving cycle efficiency such as the externally fired combined cycle (EFCC), humidified air turbine (HAT), EFGT with fuel cells and other cycles are reviewed thoroughly.

Emerging Energy-Efficiency and Greenhouse Gas Mitigation Technologies for Emerging Energy-Efficiency and Greenhouse Gas Mitigation Technologies for the Pulp and Paper Industry Title Emerging Energy-Efficiency and Greenhouse Gas Mitigation Technologies for the Pulp and Paper Industry Publication Type Report Year of Publication 2012 Authors Kong, Lingbo, Ali Hasanbeigi, and Lynn K. Price Date Published 12/2012 Publisher Lawrence Berkeley National Laboratory Keywords emerging technologies, energy efficiency, ghg, Low Emission & Efficient Industry, pulp and paper Abstract The pulp and paper industry ranks fourth in terms of energy consumption among industries worldwide. Globally, the pulp and paper industry accounted for approximately 5 percent of total world industrial final energy consumption in 2007, and contributed 2 percent of direct carbon dioxide (CO2)emissions from industry. Worldwide pulp and paper demand and production are projected to increase significantly by 2050, leading to an increase in this industry's absolute energy use and greenhouse gas (GHG) emissions. Development of new energy-efficiency and GHG mitigation technologies and their deployment in the market will be crucial for the pulp and paper industry's mid- and long-term climate change mitigation strategies. This report describes the industry's processes and compiles available information on the energy savings, environmental and other benefits, costs, commercialization status, and references for 36 emerging technologies to reduce the industry's energy use and GHG emissions. Although studies from around the world identify a variety of sector-specific and cross-cutting energy-efficiency technologies that have already been commercialized for the pulp and paper industry, information is scarce and/or scattered regarding emerging or advanced energy-efficiency and low-carbon technologies that are not yet commercialized. The purpose of this report is to provide engineers, researchers, investors, paper companies, policy makers, and other interested parties with easy access to a well-structured resource of information on these technologies.

Dynamic gas bearing turbine technology in hydrogen plants  

Science Journals Connector (OSTI)

Dynamic Gas Bearing Turbines - although applied for helium refrigerators and liquefiers for decades - experienced limitations for hydrogen applications due to restrictions in axial bearing capacity. With a new design concept for gas bearing turbines developed in 2004 axial bearing capacity was significantly improved enabling the transfer of this technology to hydrogen liquefiers. Prior to roll-out of the technology to industrial plants the turbine bearing technology passed numerous tests in R&D test benches and subsequently proved industrial scale demonstration at Linde Gas' hydrogen liquefier in Leuna Germany. Since its installation this turbine has gathered more than 16 000 successful operating hours and has outperformed its oil bearing brother in terms of performance maintainability as well as reliability. The present paper is based on Linde Kryotechnik AG's paper published in the proceedings of the CEC 2009 concerning the application of Dynamic Gas Bearing Turbines in hydrogen applications. In contrast to the former paper this publication focuses on the steps towards final market launch and more specifically on the financial benefits of this turbine technology both in terms of capital investment as well as operating expenses.

Jain and Ruben Juanes Venue: 2008 Offshore Technology Conference, Houston, Texas, May 5-8, 2008 ( http://www.spe.org and http://www.smenet.org [external sites] ) Abstract: A spectrum of behavior is encountered in methane hydrate provinces, especially ocean sediments, ranging from essentially static accumulations where the pore space is filled with hydrate and brine, to active seeps where hydrate and methane gas phase co-exist in the hydrate stability zone (HSZ). The grain-scale models of drainage and fracturing presented demonstrate key processes involved in pressure-driven gas phase invasion of a sediment. A novel extension of invasion percolation to infinite-acting, physically representative networks is used to evaluate the connectivity of water in a gas-drained sediment. A novel implementation of the level set method (LSM) is used to determine the capillarity-controlled displacement of brine by gas from sediment and from fractures within the sediment. The discrete element method (DEM) is extended to model the coupling between the pore fluids and the solid, and thereby predict the onset of sediment fracturing by gas phase pressure under in situ loading conditions. The DEM grain mechanics model accounts for the different pressure of brine and methane gas in a “membrane” two-fluid model. The fluid-fluid configuration from LSM can be mapped directly to the pore space in DEM, thereby coupling the drainage and mechanics models. The type of behavior that can emerge from the coupled processes is illustrated with an extended LSM model. The extension computes grain displacement by the gas phase with a simple kinematic rule.

Decreasing Air Emission Impacts From Oil and Gas Development Decreasing Air Emission Impacts From Oil and Gas Development Decreasing Air Emission Impacts From Oil and Gas Development Authors: Charles B. McComas, PE; J. Daniel Arthur, PE; Gerry Baker; G. Lee Moody; and David B. Cornue, PG, CHMM Venue: American Chemical Society (53rd Pentasectional Meeting) – Halliburton Energy Services Technology Center, Duncan, OK, March 8, 2008 (http://www.acs.org [external site]) Abstract: Research funded by the United States Department of Energy’s National Energy Technology Laboratory and conducted under the direction of the Interstate Oil and Gas Compact Commission has examined concerns related to air emissions resulting from domestic onshore oil and gas exploration and production operations. Current air issues such as ambient air quality standards and non-attainment areas, regulatory compliance and regional inconsistencies, as well as global climate change and carbon sequestration are a few of the subjects perceived to represent potential barriers to energy development. The topic of air quality and how it relates to onshore oil and gas exploration and production activities is examined from the position of environmental sustainability. These concerns can be addressed through reasonable and prudent practices that industry may implement in order to avoid, minimize, or mitigate air emissions. Additionally, air emissions parameters that are not currently regulated (e.g.: CH4 and CO2) may become the subject of increased concern in the future and, therefore, add to the list of issues facing oil and gas exploration and production. Suggestions for further research opportunities with the potential to benefit responsible energy resource development are also presented.

Designing a Pilot-Scale Experiment for the Production of Natural Gas Hydrates and Sequestration of CO2 in Geologic Reservoirs Designing a Pilot-Scale Experiment for the Production of Natural Gas Hydrates and Sequestration of CO2 in Geologic Reservoirs Designing a Pilot-Scale Experiment for the Production of Natural Gas Hydrates and Sequestration of CO2 in Geologic Reservoirs Authors: Mark White and Pete McGrail Venue: The 9th International Conference on Greenhouse Gas Technologies will be held November 16-20, 2008 at The Omni Shoreham Hotel in Washington, DC. The Conference will be organized by MIT in collaboration with the IEA Greenhouse Gas R&D Programme (IEA GHG), with major sponsorship from the US Department of Energy. http://mit.edu/ghgt9/ . Abstract: Under high pressure and low temperature conditions small nonpolar molecules (typically gases) can combine with water to form crystalline structures known as clathrate hydrates. Methane (CH4) and carbon dioxide (CO2) form nearly identical clathrate structures (sI), with the CO2 hydrate being thermodynamically favored. Vast accumulations of methane hydrates have been found in suboceanic deposits and beneath the arctic permafrost. Because of the large volumetric storage densities, clathrate hydrates on the deep ocean floor have been suggested as a sequestration option for CO2. Alternatively, CO2 hydrates can be formed in the geologic settings of naturally occurring accumulations of methane hydrates. Global assessments of natural gas resources have shown that gas hydrate resources exceed those of conventional resources, which is indicative of the potential for clathrate hydrate sequestration of CO2. Recovery of natural gas from hydrate-bearing geologic deposits has the potential for being economically viable, but there remain significant technical challenges in converting these natural accumulations into a useable resource. Currently, conventional methods for producing methane hydrates from geologic settings include depressurization, thermal stimulation, and inhibitor injection. Although CO2 clathrates generally are not naturally as abundant as those of CH4, their occurrence forms the foundation of an unconventional approach for producing natural gas hydrates that involves the exchange of CO2 with CH4 in the hydrate structure. This unconventional concept has several distinct benefits over the conventional methods: 1) the heat of formation of CO2 hydrate is greater than the heat of dissociation of CH4 hydrate, providing a low-grade heat source to support additional methane hydrate dissociation, 2) exchanging CO2 with CH4 will maintain the mechanical stability of the geologic formation, and 3) the process is environmentally friendly, providing a sequestration mechanism for the injected CO2. The exchange production technology would not be feasible without the favorable thermodynamics of CO2 hydrates over CH4 hydrates. This situation yields challenges for the technology to avoid secondary hydrate formation and clogging of the geologic repository. Laboratory-scale experiments have demonstrated the feasibility of producing natural gas and sequestering CO2 using the direct exchange technology in geologic media. These experiments have duplicated numerically using the STOMP-HYD simulator, which solves the nonisothermal multifluid flow and transport equations for mixed hydrate systems in geologic media. This paper describes the design (via numerical simulation) of a pilot-scale demonstration test of the CO2 exchange production and sequestration technology for a geologic setting beneath the arctic permafrost, involving a gas-hydrate interval overlying a free-gas interval (i.e., Class 1 Hydrate Accumulation).

Sizzling Qatar boom sparked by foreign money, technology, and gas  

SciTech Connect

International oil companies have collected advanced upstream and downstream technology and focused it on the small Persian Gulf emirate of Qatar, a roughly 110 mile long by 50 mile wide, thumb-like peninsula that juts out from Saudi Arabia. The emirate, in a burst of enlightened self interest, has opened its doors to international companies and is now riding a wave of foreign investment and new technology to major increases in oil, natural gas, and petrochemical production. The largest natural gas reserve in the world is under Qatari waters and is the driver for the activity that includes two LNG plants. Qatar has proven that you don`t need crude oil in the Persian Gulf to be important. Activities are discussed.

Gas Foil Bearing Technology Advancements for Closed Brayton Cycle Turbines  

Science Journals Connector (OSTI)

Closed Brayton Cycle (CBC) turbine systems are under consideration for future space electric power generation. CBC turbines convert thermal energy from a nuclear reactor or other heat source to electrical power using a closed?loop cycle. The operating fluid in the closed?loop is commonly a high pressure inert gas mixture that cannot tolerate contamination. One source of potential contamination in a system such as this is the lubricant used in the turbomachine bearings. Gas Foil Bearings (GFB) represent a bearing technology that eliminates the possibility of contamination by using the working fluid as the lubricant. Thus foil bearings are well suited to application in space power CBC turbine systems. NASA Glenn Research Center is actively researching GFB technology for use in these CBC power turbines. A power loss model has been developed and the effects of very high ambient pressure start?up torque and misalignment have been observed and are reported here.

New generation enrichment monitoring technology for gas centrifuge enrichment plants  

SciTech Connect

The continuous enrichment monitor, developed and fielded in the 1990s by the International Atomic Energy Agency, provided a go-no-go capability to distinguish between UF{sub 6} containing low enriched (approximately 4% {sup 235}U) and highly enriched (above 20% {sup 235}U) uranium. This instrument used the 22-keV line from a {sup 109}Cd source as a transmission source to achieve a high sensitivity to the UF{sub 6} gas absorption. The 1.27-yr half-life required that the source be periodically replaced and the instrument recalibrated. The instrument's functionality and accuracy were limited by the fact that measured gas density and gas pressure were treated as confidential facility information. The modern safeguarding of a gas centrifuge enrichment plant producing low-enriched UF{sub 6} product aims toward a more quantitative flow and enrichment monitoring concept that sets new standards for accuracy stability, and confidence. An instrument must be accurate enough to detect the diversion of a significant quantity of material, have virtually zero false alarms, and protect the operator's proprietary process information. We discuss a new concept for advanced gas enrichment assay measurement technology. This design concept eliminates the need for the periodic replacement of a radioactive source as well as the need for maintenance by experts. Some initial experimental results will be presented.

Gas and Oil in Utah: Potential, New Discoveries, and Hot Plays Gas and Oil in Utah: Potential, New Discoveries, and Hot Plays Gas and Oil in Utah: Potential, New Discoveries, and Hot Plays Author: Thomas C. Chidsey, Petroleum Section Chief, Utah Geological Survey, Salt Lake City, UT. Venue: International Oil Scouts Association’s 84th annual meeting, Stein Eriksen Lodge, Park City, UT, June 17–20, 2007, (http://www.oilscouts.com/index-main.html [external site]). Abstract: Utah’s natural gas and oil exploration history extends back more than 100 years, fluctuating greatly due to discoveries, price trends, and changing exploration targets. During the boom period of the early 1980s, activity peaked at over 500 wells per year. After slowing in the 1990s, drilling activity has again increased, reaching an all-time peak of 1,058 wells spudded and over 2,000 APDs (application for permit to drill) filed in 2006. This increase in activity has been spurred by high prices for both natural gas and oil and by the perception that Utah is highly prospective and underexplored. In recent years, the proportion of new wells exploring for gas has increased greatly. Total cumulative natural gas production from Utah fields now exceeds 8 Tcf. Recent successful drilling has been expanding reserves by about 10 percent per year, one of the highest rates of gas reserves increase in the country. Although gas production from some fields declined during the late 1990s, two factors caused overall gas production to increase. The development of coalbed natural gas (CBNG) accumulations in the Cretaceous Ferron Sandstone play, in particular Drunkards Wash field in central Utah, has increased the State’s annual gas production by 20–30 percent. Also, deeper exploratory and development drilling in the eastern and southern Uinta Basin during the past 5 years has led to discoveries of substantial gas accumulations in tight-sand reservoirs of the Tertiary Wasatch Formation, Cretaceous Mesaverde Group, and Jurassic Entrada and Wingate Sandstones. Significant potential exists for other coalfields (Book Cliffs, Sego, and Wasatch Plateau) around the Uinta Basin to yield CBNG, and the extent of deeper conventional and tight-gas plays remains to be explored. In addition, shale gas reservoirs in the Mississippian Manning Canyon Shale, Pennsylvanian Hermosa Group, and Cretaceous Mancos Shale of central, southeastern, and northeastern Utah, respectively, have tremendous untapped potential. Utah oilfields have produced a cumulative total of 1.3 billion barrels (bbl) of oil. Although annual production decreased from a peak of 41 million bbl in 1985 to 13 million bbl in 2003, the trend has since reversed, and 2005 production reached nearly 17 million bbl. A component (about one-third of the increase) of this turnaround has been the 2004 discovery of Covenant field in the central Utah thrust belt, or "Hingeline." This new field has already produced 3 million bbl of Mississippian-sourced oil from the Jurassic Navajo Sandstone in a thrusted anticline formed during the Sevier orogeny. This new oil play is the focus of extensive leasing and exploration activity—comparable to the late 1970s and early 1980s in the Utah-Wyoming salient of the thrust belt to the north.

Mapping Study to Characterize NSCR Performance on a Natural Gas-Fueled Engine Mapping Study to Characterize NSCR Performance on a Natural Gas-Fueled Engine Mapping Study to Characterize NSCR Performance on a Natural Gas-Fueled Engine Authors: Mohamed Toema (speaker), Sarah Nuss-Warren, and Kirby S. Chapman, Kansas State University National Gas Machinery Laboratory; James McCarthy and Thomas McGrath, Innovative Environmental Solutions Inc. Venue: ASME Internal Combustion Engine Division 2009 Spring Technical Conference, May 3–6, Milwaukee, WI. http://www.asmeconferences.org/ICES09/index.cfm [external site]. Abstract: The researchers are conducting a project to characterize pollutant emissions performance of field gas-fired four-stroke cycle rich burn engines equipped with non-selective catalytic reduction (NSCR) technology. Engine emissions and operating parameters are being monitored on three engines over an extended period. In addition, a mapping study was conducted on one engine. The NSCR was operated at various controlled air-to-fuel (AF) ratios while emission measurements were conducted and engine operating parameters monitored. NOx, CO, and oxygen were measured using both EPA reference method technology and the portable analyzer used in the long-term study. In the mapping study, ammonia, formaldehyde, CO, NOx, and speciated hydrocarbon emissions were recorded in real-time using an extractive FTIR system. This paper focuses on the engine mapping phase. The mapping tests demonstrated a trade-off between NOx emissions and CO, ammonia, and hydrocarbon emissions. Richer engine operation (lower AF) decreases NOx emissions at the expense of higher CO, ammonia, and hydrocarbons. Leaner operation has the opposite effect. The results to date of the semi-continuous monitoring are presented in a separate paper.

Government works with technology to boost gas output/usage  

SciTech Connect

Specially treated ethane gas from fields of the Moomba area in the Cooper basin of South Australia now flows freely through 870 mi of interstate gas pipeline to an end-user in Sydney, New South Wales. This unprecedented usage of ethane is the result of a long-term cooperative agreement. The producer sought to provide the end-user with ethane gas for usage as a petrochemical feedstock to manufacture ethylene and plastic goods. The end-user had strict specifications for a low-CO{sub 2}, very dry ethane product with a small percentage of methane. In order to meet these, the producer committed millions of dollars to construct a high-technology, state-of-the-art ethane treatment facility in the Moomba area, and lay an extensive pipeline. Santos also contracted with the amines supplier to provide a high-performance, deep CO{sub 2} removal solvent with good corrosion prevention characteristics. The paper discusses the Moomba field overflow, gas treatment, government cooperation, and project completion.

Variation in Long-Term Emissions Data from NSCR-Equipped Natural Gas-Fueled Engine Variation in Long-Term Emissions Data from NSCR-Equipped Natural Gas-Fueled Engine Variation in Long-Term Emissions Data from NSCR-Equipped Natural Gas-Fueled Engine Authors: Kirby S. Chapman (speaker), Mohamed Toema, and Sarah Nuss-Warren, Kansas State University National Gas Machinery Laboratory. Venue: ASME Internal Combustion Engine Division 2009 Spring Technical Conference, May 3–6, Milwaukee, WI. http://www.asmeconferences.org/ICES09/index.cfm [external site]. Abstract: This paper describes work on a project to characterize pollutant emissions performance of non-selective catalytic reduction (NSCR) technology, including a catalyst and air-to-fuel ratio controller (AFRC), applied to four-stroke cycle rich-burn engines. Emissions and engine data were collected semi-continuously with a portable emissions analyzer on three engines in the Four Corners area. In addition, periodic emissions measurements that included ammonia were conducted several times. Data collected from October 2007 through August 2008 show significant variation in emissions levels over hours, days, and longer periods of time, as well as seasonal variation. As a result of these variations, simultaneous control of NOx to below a few hundred parts per million (ppm) and CO to below 1,000 ppm volumetric concentration was not consistently achieved. Instead, the NSCR/AFRC systems were able to simultaneously control both species to these levels for only a fraction of the time the engines were monitored. Both semi-continuous emissions data and periodically collected emissions data support a NOx-CO trade-off and a NOx-ammonia tradeoff in NSCR-equipped engines.

Natural gas and efficient technologies: A response to global warming  

SciTech Connect

It has become recognized by the international scientific community that global warming due to fossil fuel energy buildup of greenhouse CO{sub 2} in the atmosphere is a real environmental problem. Worldwide agreement has also been reached to reduce CO{sub 2} emissions. A leading approach to reducing CO{sub 2} emissions is to utilize hydrogen-rich fuels and improve the efficiency of conversion in the power generation, transportation and heating sectors of the economy. In this report, natural gas, having the highest hydrogen content of all the fossil fuels, can have an important impact in reducing CO{sub 2} emissions. This paper explores natural gas and improved conversion systems for supplying energy to all three sectors of the economy. The improved technologies include combined cycle for power generation, the Carnol system for methanol production for the transportation sector and fuel cells for both power generation and transportation use. The reduction in CO{sub 2} from current emissions range from 13% when natural gas is substituted for gasoline in the transportation sector to 45% when substituting methanol produced by the Carnol systems (hydrogen from thermal decomposition of methane reacting with CO{sub 2} from coal-fired power plants) used in the transportation sector. CO{sub 2} reductions exceeding 60% can be achieved by using natural gas in combined cycle for power generation and Carnol methanol in the transportation sector and would, thus, stabilize CO{sub 2} concentration in the atmosphere predicted to avoid undue climate change effects. It is estimated that the total fossil fuel energy bill in the US can be reduced by over 40% from the current fuel bill. This also allows a doubling in the unit cost for natural gas if the current energy bill is maintained. Estimates of the total net incremental replacement capital cost for completing the new improved equipment is not more than that which will have to be spent to replace the existing equipment conducting business as usual.

Coupled Hydrological, Thermal and Geomechanical Analysis of Wellbore Stability in Hydrate-Bearing Sediments Coupled Hydrological, Thermal and Geomechanical Analysis of Wellbore Stability in Hydrate-Bearing Sediments Coupled Hydrological, Thermal and Geomechanical Analysis of Wellbore Stability in Hydrate-Bearing Sediments (OTC 19672) Authors: Jonny Rutqvist (speaker), George J. Moridis, and Tarun Grover Venue: 2008 Offshore Technology Conference, Houston, Texas, May 5-8, 2008 ( http://www.spe.org and http://www.smenet.org [external sites] ) Abstract: This study investigated coupled multiphase flow, themal, thermodynamic and geomechanical behavior of oceanic Hydrate Bearing Sediments (HBS), during depressurization-induced gas production in general, and potential wellbore in-stability and casing deformation in particular. The project investigated the geomechanical changes and wellbore stability for two alternative cases of production using a horizontal well in a Class 3 deposit and a vertical well in a Class 2 deposit. The research compared the geomechanical responses and the potential adverse geomechanical effects for the two different cases. Analysis shows that geomechanical responses during depressurization-induced gas production from oceanic hydrate deposits is driven by the reservoir-wide pressure decline (Delta P), which in turn is controlled by the induced pressure decline near the wellbore. Because any change quickly propagates within the entire reservoir, the reservoir wide geomechanical response can occur within a few days of production induced pressure decline.

Review of technologies for oil and gas produced water treatment  

Science Journals Connector (OSTI)

Produced water is the largest waste stream generated in oil and gas industries. It is a mixture of different organic and inorganic compounds. Due to the increasing volume of waste all over the world in the current decade, the outcome and effect of discharging produced water on the environment has lately become a significant issue of environmental concern. Produced water is conventionally treated through different physical, chemical, and biological methods. In offshore platforms because of space constraints, compact physical and chemical systems are used. However, current technologies cannot remove small-suspended oil particles and dissolved elements. Besides, many chemical treatments, whose initial and/or running cost are high and produce hazardous sludge. In onshore facilities, biological pretreatment of oily wastewater can be a cost-effective and environmental friendly method. As high salt concentration and variations of influent characteristics have direct influence on the turbidity of the effluent, it is appropriate to incorporate a physical treatment, e.g., membrane to refine the final effluent. For these reasons, major research efforts in the future could focus on the optimization of current technologies and use of combined physico-chemical and/or biological treatment of produced water in order to comply with reuse and discharge limits.

Water management technologies used by Marcellus Shale Gas Producers.  

SciTech Connect

Natural gas represents an important energy source for the United States. According to the U.S. Department of Energy's (DOE's) Energy Information Administration (EIA), about 22% of the country's energy needs are provided by natural gas. Historically, natural gas was produced from conventional vertical wells drilled into porous hydrocarbon-containing formations. During the past decade, operators have increasingly looked to other unconventional sources of natural gas, such as coal bed methane, tight gas sands, and gas shales.

Field Evaluation of a Surfactant-Modified Zeolite System for Removal of Organics from Produced Water Field Evaluation of a Surfactant-Modified Zeolite System for Removal of Organics from Produced Water Field Evaluation of a Surfactant-Modified Zeolite System for Removal of Organics from Produced Water Authors: Robert S. Bowman, New Mexico Technological University, Socorro, NM; Enid J. Sullivan, Los Alamos National Laboratory, Los Alamos, NM; and Lynn E. Katz and Kerry A. Kinney, University of Texas, Austin, TX. Venue: 44th Annual Meeting of the Clay Minerals Society in Santa Fe, NM, June 3–7, 2007 (http://www.clays.org/home/HomeAnnualMeeting.html [external site]). Abstract: About 2.3 billion cubic meters (600 billion gallons) of wastewater (produced water) is generated each year as a byproduct of oil and gas operations in the continental United States. Disposal of this water represents about 10% of the cost of hydrocarbon production. Inexpensive treatment technologies can lower the cost of disposal and generate higher-quality water for other uses. Surfactant-modified zeolite (SMZ) has been shown to effectively sorb a variety of nonpolar organic compounds from water. SMZ was tested as a medium to remove benzene, toluene, ethylbenzene, and xylenes (BTEX) from produced water generated during extraction of coalbed natural gas. BTEX removal is necessary prior to surface discharge of produced waters or as a pretreatment for reverse osmosis. We demonstrated in laboratory column experiments that BTEX-saturated SMZ is readily regenerated by air sparging. There was no loss in BTEX sorption capacity, and a minor decrease in hydraulic conductivity, after 50 sorption/regeneration cycles. Based upon the laboratory results, a pilot-scale produced-water treatment system was designed and tested at a reinjection facility in the San Juan Basin of New Mexico. The SMZ-based system was designed to treat up to 110 liters (30 gallons) of produced water per hour on a continuous basis by running two SMZ columns in series. The system performed as predicted, based on laboratory results, over repeated feed and regeneration cycles during the month-long operation. The BTEX-laden sparge gases were treated with a vapor-phase bioreactor system, resulting in an emissions-free process

Numerical Studies of Geomechanical Stability of Hydrate-Bearing Sediments Numerical Studies of Geomechanical Stability of Hydrate-Bearing Sediments Authors: George J. Moridis, Jonny Rutqvist, Lawrence Berkeley National Laboratory. Venue: 2007 Offshore Technology Conference, Houston, TX, April 30–May 1, 2007 (http://www.otcnet.org/ [external site]). Abstract: The thermal and mechanical loading of hydrate-bearing sediments (HBS) can result in hydrate dissociation and a significant pressure increase, with potentially adverse consequences on the integrity and stability of the wellbore assembly, the HBS, and the bounding formations. The perception of HBS instability, coupled with insufficient knowledge of their geomechanical behavior and the absence of predictive capabilities, has resulted in a strategy of avoidance of HBS when locating offshore production platforms. These factors can also impede the development of hydrate deposits as gas resources. For the analysis of the geomechanical stability of HBS, project researchers developed and used a numerical model that integrates a commercial geomechanical code into a simulator describing the coupled processes of fluid flow, heat transport, and thermodynamic behavior in geologic media. The geomechanical code includes elastoplastic models for quasi-static yield and failure analysis and viscoplastic models for time-dependent (creep) analysis. The hydrate simulator can model the non-isothermal hydration reactions (equilibrium or kinetic), phase behavior, and flow of fluids and heat in HBS, and can handle any combination of hydrate dissociation mechanisms. The simulations can account for the interdependence of changes in the hydraulic, thermodynamic, and geomechanical properties of the HBS, in addition to swelling/shrinkage, displacement (subsidence), and possible geomechanical failure. Researchers investigated in three cases the coupled hydraulic, thermodynamic, and geomechanical behavior of oceanic HBS systems. The first involves hydrate heating as warm fluids from deeper, conventional reservoirs ascend to the ocean floor through uninsulated pipes intersecting the HBS. The second case involves mechanical loading caused by the weight of structures placed on HBS at the ocean floor, and the third describes system response during gas production from a hydrate deposit. The results indicate that the stability of HBS in the vicinity of warm pipes may be significantly affected, especially near the ocean floor where the sediments are unconsolidated and more compressible. Conversely, the increased pressure caused by the weight of structures on the ocean floor increases the stability of hydrates, while gas production from oceanic deposits minimally affects the geomechanical stability of HBS under the conditions that are deemed desirable for production.

Characterization of Nonequilibrium Sorption of Gasoline Components by Surfactant-Modified Zeolite Characterization of Nonequilibrium Sorption of Gasoline Components by Surfactant-Modified Zeolite Characterization of Nonequilibrium Sorption of Gasoline Components by Surfactant-Modified Zeolite Authors: Joshua A. Simpson and Robert S. Bowman, New Mexico Technological University, Socorro, NM Venue: 44th Annual Meeting of the Clay Minerals Society in Santa Fe, NM, June 3–7, 2007 (http://www.clays.org/home/HomeAnnualMeeting.html [external site]). Abstract: Surfactant-modified zeolite (SMZ) has been shown to effectively remove benzene, toluene, ethylbenzene, and xylene (BTEX) from water generated during oil and natural gas production (produced water). The BTEX sorption isotherms are linear and noncompetitive, suggesting that the removal mechanism is partitioning into the surfactant’s hydrophobic bilayer formed on SMZ. Even though BTEX sorption in batch systems is rapid, chemical equilibrium models do not accurately describe BTEX transport through packed beds of SMZ. Comparison with transport of a nonreactive tracer (tritium) suggests that two-site, diffusive nonequilibrium sorption-desorption controls BTEX transport. We conducted batch experiments with SMZ to determine the nonequilibrium sorption kinetics of each BTEX constituent. The kinetic measurements were used to parameterize a nonequilibrium transport model to predict BTEX removal under varying flow conditions. The accuracy of predictions is being tested using laboratory column experiments with produced water from the San Juan Basin of New Mexico

Mechanical strength and seismic property measurements of hydrate-bearing sediments Mechanical strength and seismic property measurements of hydrate-bearing sediments Mechanical strength and seismic property measurements of hydrate-bearing sediments (HBS) during hydrate formation and loading tests (OTC 19559) Authors: Seiji Nakagawa (speaker), Timothy J. Kneafsey, and George J. Moridis Venue: 2008 Offshore Technology Conference, Houston, Texas, May 5-8, 2008 http://www.spe.org and http://www.smenet.org [external sites] Abstract: An on-going effort on conducting laboratory triaxial compression tests on synthetic methane hydrate-bearing sediment cores is presented. Methane hydrate is formed within a sand pack inside a test cell under controlled temperature and confining stress, and triaxial compression tests are performed while monitoring seismic properties. A unique aspect of the experiment is that the formation and dissociation of hydrate in a sediment core, and the failure of the sample during loading tests, can be monitored in real time using both seismic waves and x-ray CT imaging. For this purpose, a specially designed triaxial (geomechanical) test cell was built. This cell allows for conducting seismic wave measurements on a sediment core using compressional and shear (torsion) waves. Concurrently, CT images can be obtained through an x-ray-transparent cell wall. These are used to determine the porosity distribution within a sample owing to both original sand packing and formation of hydrate in the pore space. For interpreting the results from both seismic measurements and geomechanical tests, characterization of sample heterogeneity can be critically important. In this paper, the basic functions of the test cell are presented, with the results of preliminary experiments using non-hydrate bearing sandpack and sandstone core. These measurements confirmed that (1) clear x-ray images of gas-fluid boundaries within a sediment/rock core can be obtained through a thick aluminum test cell wall, (2) the test cell functions correctly during loading tests, and (3) both compressional and shear waves can be measured during a loading test. Further experiments using methane-hydrate-bearing samples will be presented at the conference

The barrier was temperature. Above 2300 degrees F, available cooling technologies were insufficient to protect the turbine blades and other internal components from heat degradation. Since higher temperatures are the key to higher efficiencies, this effectively limited the generating efficiency at which a turbine power plant could convert the energy in the fuel into electricity.

Pore-Scale Mechanistic Study of the Preferential Mode of Hydrate Formation in Sediments: Fluid Flow Aspects Pore-Scale Mechanistic Study of the Preferential Mode of Hydrate Formation in Sediments: Fluid Flow Aspects Pore-Scale Mechanistic Study of the Preferential Mode of Hydrate Formation in Sediments: Fluid Flow Aspects Authors: Javad Behseresht, Masa Prodanovic, and Steven Bryant, University of Texas at Austin. Venue: American Geophysical Union fall meeting, San Francisco, CA, December 10-14, 2007 (http://www.agu.org/meetings/fm07/ [external site]). Abstract: A spectrum of behavior is encountered in ocean sediments bearing methane hydrates, ranging from essentially static accumulations where hydrate and brine co-exist, to active cold seeps where hydrate and a methane gas phase co-exist in the hydrate stability zone (HSZ). In this and a companion paper (Jain and Juanes), the researchers describe methods to test the following hypothesis: The coupling between drainage and fracturing, both induced by pore pressure, determines whether methane gas entering the HSZ is converted completely to hydrate. The researchers will describe a novel implementation of the level set method to determine the capillarity-controlled displacement of brine by gas from sediment and from fractures within the sediment. Predictions of fluid configurations in infinite-acting-model sediments indicate that the brine in drained sediment (after invasion by methane gas) is better connected than previously believed. This increases the availability of water and the rate of counter-diffusion of salinity ions, thus relaxing the limit on hydrate build-up within the gas-invaded grain matrix. Simulated drainage of a fracture in sediment shows that points of contact between fracture faces are crucial. They allow residual water saturation to remain within an otherwise gas-filled fracture. Simulations of imbibition—which can occur, for example, after drainage into surrounding sediment reduces gas phase pressure in the fracture—indicate that the gas/water interfaces at contact points significantly shift the threshold pressures for withdrawal of gas. During both drainage and imbibition, the contact points greatly increase water availability for hydrate formation within the fracture. The researchers will discuss coupling this capillarity-controlled displacement model with a discrete element model for grain-scale mechanics. The coupled model provides a basis for evaluating the macroscopic conditions (thickness of gas accumulation below the hydrate stability zone, average sediment grain size, principal earth stresses) favoring co-existence of methane gas and hydrate in the HSZ. Explaining the range of behavior is useful in assessing resource volumes and evaluating pore-to-core scale flow paths in production strategies

Reactive transport modeling of oceanic gas hydrate instability and dissociation in response to climate change Reactive transport modeling of oceanic gas hydrate instability and dissociation in response to climate change Reactive transport modeling of oceanic gas hydrate instability and dissociation in response to climate change Authors: Matthew T. Reagan and George J. Moridis Venue: 6th International Conference on Gas Hydrates 2008, Vancouver, British Columbia, July 9-12, 2008 (http://www.icgh.org [external site]) Abstract: Paleoceanographic evidence has been used to postulate that methane from oceanic hydrates may have had a significant role in regulating past global climate. The implication is that global oceanic deposits of methane gas hydrate is the main culprit for a sequence of rapid global warming affects that occurred during the late Quaternary period. However, the behavior of contemporary oceanic methane hydrate deposits subjected to rapid temperature changes, like those predicted under future climate change scenarios, is poorly understood. To determine the fate of the carbon stored in these hydrates, we performed coupled thermo-hydrological-chemical simulations of oceanic gas hydrate accumulations subjected to temperature changes at the seafloor, and assessed the potential for methane release into the ecosystem. Our modeling analysis considered the properties of benthic sediments, the saturation and distribution of the hydrates, the ocean depth, the initial seafloor temperature, and the effects of benthic biogeochemical activity. The results show that while many deep hydrate deposits are indeed stable during periods of rapid ocean temperature changes, shallow deposits (such as those found in arctic regions or in the Gulf of Mexico) can undergo rapid dissociation and produce significant carbon fluxes over a period of decades. These fluxes may exceed the ability of the seafloor environment (via anaerobic oxidation of methane and the formation of carbonates) to sequester the released carbon. This model will provide a source term to regional or global climate models in order to assess the coupling of gas hydrate deposits to changes in the global climate.

Production Strategies for Marine Hydrate Reservoirs Production Strategies for Marine Hydrate Reservoirs Production Strategies for Marine Hydrate Reservoirs Authors: J. Phirani. & K. K. Mohanty Venue: 6th International Conference on Gas Hydrates (ICGH 2008), Vancouver, British Columbia, CANADA, July 6-10, 2008. http://www.ichg.org/showcontent.aspx?MenuID=287 [external site]. Abstract: Large quantities of natural gas hydrate are present in marine sediments. This research is aimed at assessing production of natural gas from these deposits. We had developed a multiphase, multicomponent, thermal, 3D simulator in the past, which can simulate production of hydrates both in equilibrium and kinetic modes. Four components (hydrate, methane, water and salt) and five phases (hydrate, gas, aqueous-phase, ice and salt precipitate) are considered in the simulator. The intrinsic kinetics of hydrate formation or dissociation is considered using the Kim–Bishnoi model. Water freezing and ice melting are tracked with primary variable switch method (PVSM) by assuming equilibrium phase transition. In this work, we simulate depressurization and warm water flooding for hydrate production in a hydrate reservoir underlain by a water layer. Water flooding has been studied as a function of well spacing, well orientation, and injection temperature. Results show that depressurization is limited by the supply of heat of hydrate formation. Warm water flooding can supply this heat of formation. Gas production rate is higher for the water flooding than depressurization. Optimum configuration for wells and water temperature are identified.

Gas Hydrate Research and Stratigraphic Test Results, Milne Point Unit, Alaska North Slope Gas Hydrate Research and Stratigraphic Test Results, Milne Point Unit, Alaska North Slope Gas Hydrate Research and Stratigraphic Test Results, Milne Point Unit, Alaska North Slope Authors: Robert Hunter (ASRC Energy), Scott Digert (BPXA), Tim Collett (USGS), Ray Boswell (USDOE) Venue: AAPG National Meeting Gas Hydrate session, Oral Presentation, San Antonio, TX, April 22, 2008 (http://www.AAPG.org [external site]) Abstract: This BP-DOE collaborative research project is helping determine whether or not gas hydrate can become a technically and economically recoverable gas resource. Reservoir characterization, development modeling, and associated studies indicate that 0-0.34 trillion cubic meters (TCM) gas may be technically recoverable from the estimated 0.92 TCM gas-in-place within the Eileen gas hydrate accumulation on the Alaska North Slope (ANS). Reservoir modeling indicates sufficient potential for technical recovery to justify proceeding into field operations to acquire basic reservoir and fluid data from the Mount Elbert gas hydrate prospect in the Milne Point Unit (MPU). Successful drilling and data acquisition in the Mount Elbert-01 stratigraphic test well was completed during February 3-19, 2007. Data was acquired from 131 meters of core (30.5 meters gas hydrate-bearing), extensive wireline logging, and wireline production testing operations using Modular Dynamics Testing (MDT). The stratigraphic test validated the 3D seismic interpretation of the MPU gas hydrate-bearing Mount Elbert prospect. Onsite core sub- sampling preserved samples for later analyses of interstitial water geochemistry, physical properties, thermal properties, organic geochemistry, petrophysics, and mechanical properties. MDT testing was accomplished within two gas hydrate-bearing intervals, and acquired during four long shut-in period tests. Four gas samples and one pre-gas hydrate dissociation formation water sample were collected. MDT analyses are helping to improve understanding of gas hydrate dissociation, gas production, formation cooling, and long-term production potential as well as help calibrate reservoir simulation models.

Physical properties of sediment from the 2006 National Gas Hydrate Program expedition offshore India Physical properties of sediment from the 2006 National Gas Hydrate Program expedition offshore India Physical properties of sediment from the 2006 National Gas Hydrate Program expedition offshore India Authors: Winters, W.J., (U.S. Geological Survey, speaker), Gomes, M., Giosan, L., Johnson, J., Kastner, M., Torres, M.E., Long, P.E., Schaef, H.T., Rose, K., and the NGHP-01 Shipboard Scientific Party. Venue: India’s Directorate General of Hydrocarbons’ International Conference on Gas Hydrates in Nodia (New Delhi), India, February 6–8, 2008 (http://www.dghindia.org/site/pdfattachments/upcomingevents/Updated_Programme_gAS[1].pdf [PDF-external site]). Abstract: The scientific goals of the NGHP Expedition 01 physical properties program are to a) constrain baseline index properties of host sediment; b) ground-truth well-log, seismic, and other shipboard data sets; c) relate textural characteristics to gas hydrate occurrence and small-scale porous media effects; and d) relate index properties and textural analyses to gas hydrate occurrence and regional sedimentologic interpretations. During the shipboard phase of NGHP-01, baseline bulk physical properties, such as water content, grain density, bulk density, and porosity, were determined on more than 1,800 sediment samples from 14 sites located in four study areas. Overall, physical properties change more significantly near the seafloor, then at a much more gradual rate with depth. The transition depth varies between sites but can range from about 12 to as deep as 200 meters beneath the seafloor. In addition, shear strength, electrical resistivity, magnetic susceptibility, thermal conductivity, and acoustic velocity measurements were conducted to further characterize the sediment. These measurements, when combined with sedimentologic and geochemical studies, delineate the role of the host sediment in hydrate formation and occurrence and are used in modeling the response of hydrate-bearing sediment to natural change or drilling operations. Strong correlation typically exists between physical properties determined from shipboard analyses and well-log studies. More than 500 shore-based grain-size analyses have been conducted that indicate that most sediment is characterized as clayey silt to silty clay with a median grain size that is near or slightly greater than the silt-clay boundary. Grain-size analyses are being conducted on samples identified by infrared imaging as having high concentrations of gas hydrate in recovered core samples. These analyses will be used to study porous-media effects and geologic controls on the occurrence of gas hydrate in situ.

Shale gas for the petrochemical industry: Incorporation of novel technologies  

Science Journals Connector (OSTI)

Abstract In this work, a new shale gas-based polygeneration system with essentially zero CO2 emissions is proposed that co-produces methanol, dimethyl ether (DME), olefins and power. The thermal and economic analysis of the proposed process is performed to determine the optimum product portfolio regarding current market prices. The optimization results show that production of methanol/DME and power can improve the performance of the olefin production section significantly. Therefore, the proposed plant can link the shale gas industry to the petrochemical sector efficiently and in an environmentally friendly way.

Recent developments in gas turbine materials and technology and their implications for syngas firing  

Science Journals Connector (OSTI)

Gas turbine combined-cycle systems burning natural gas represent a reliable and efficient power generation technology that is widely used. A critical factor in their development was the rapid adaptation of aero-engine technology (single crystal airfoils, sophisticated cooling techniques, and thermal barrier coatings) in order to operate at the high rotor-inlet temperatures required for high efficiency generation. Early reliability problems have been largely overcome, so that this type of power generation system is now considered to be a mature technology capable of achieving high levels of availability. Current interest in replacing natural gas with gas derived from coal (syngas or hydrogen) in these gas turbine systems focuses attention on implications for the critical turbine components. In this paper, the development requirements for materials for critical hot gas-path parts in large gas turbines burning coal-derived syngas fuels are briefly considered in the context of the state-of-the-art in materials for engines burning natural gas. It is shown that, despite some difficult design issues, many of the materials used in current engines will be applicable to units burning syngas. However, there is the potential that the durability of some components may be prejudiced because of differences in the combustion environment (especially in terms of water vapor content, and possibly sulfur compounds and particulates). Consequently, effort to develop improved coatings to resist erosion and also attack by S-containing compounds may be necessary.

Venue: AGU Fall Meeting, San Francisco, CA, December 15-19 2008 -- Session OS25: Methane Flux from Naturally Occurring Marine Gas Hydrates http://www.agu.org Abstract: The recently funded DOE/NETL study "HyFlux: Remote sensing and sea-truth measurements of methane flux to the atmosphere" (see MacDonald et al.: HyFlux - Part I) will combine sea surface, water column and shallow subsurface observations to improve our estimates of methane flux from submarine seeps and associated gas hydrate deposits to the water column and atmosphere along the Gulf of Mexico continental margin and other selected areas world-wide. As methane-rich fluids rise towards the sediment-water interface, they will interact with sulfate-rich pore fluids derived from overlying bottom water, which results in the formation of an important biogeochemical redox boundary, the so-called sulfate-methane interface, or SMI. Both methane and sulfate are consumed within the SMI and dissolved inorganic carbon, mostly bicarbonate (HCO3-) and hydrogen sulfide are produced, stimulating authigenic carbonate precipitation at and immediately below the SMI. Accordingly, the formation of authigenic carbonates in methane- and gas-hydrate-rich sediments will sequester a portion of the methane-derived carbon. To date, however, little is known about the quantitative aspects of these reactions. Rates of DIC production are not well constrained, but recent biogeochemical models indicate that CaCO3 precipitation rates may be as high as 120 µmol cm-2a-1. Therefore, AOM-driven carbonate precipitation must be considered when assessing the impact of gas-hydrate-derived methane on the global carbon cycle.

Simulation of the system behavior of hydrate-bearing geologic media involves solving fully coupled mass and heat balance equations. The models need to simulate equilibrium or kinetic processes of hydrate formation and dissociation. TOUGH+HYDRATE is a widely used code for gas hydrate simulations. The code can model non-isothermal gas release, phase changes and flow of fluids and heat. It accounts for up to four mass components and four possible phases. Because hydrate simulations require intensive computational effort, many studies that involve serial processors are limited by problems of complexity and scale. With the growing availability of multi-core CPUs, Linux clusters, and super-computers, the use of parallel processing methods is a distinct advantage. This study develops a domain decomposition approach for large-scale gas hydrate simulations using parallel computation. The approach partitions the simulation domain into small sub-domains. The full simulation domain is simulated integrally by using multiple processes. Each process will be in charge of one portion of the simulation domain for updating thermophysical properties, assembling mass and energy balance equations, solving linear equation systems, and performing other local computations. The linear equation systems are solved in parallel by multiple processes with a parallel linear solver. The multiple processes are run in parallel on shared- or distributed memory multiple-CPU computers. A hybrid approach, running multiple processes in each CPU and using multiple CPUs, may achieve additional speedup. During calculations, communication between processes is needed to update sub-domain boundary parameters. An efficient inter-process communication scheme has been developed. The new approach was implemented into the TOUGH+HYDRATE code and demonstrates excellent speedup and very good scalability. For many large-scale problems, this method can obtain linear or super-linear speedup. This paper will show applications of the new approach to simulate three dimensional field-scale models for gas production from gas-hydrate

The geomechanical response of Hydrate-Bearing Sediments (HBS) is a serious concern that needs to be addressed before the installation of facilities for hydrate deposits can proceed, and if gas production from hydrate deposits is to become reality. HBS are often unconsolidated, and are characterized by low shear strength. Heat from external sources, that cross the formation or depressurization-based production, can induce dissociation of hydrates (a strong cementing agent), and degradation of the structural stability of the HBS. Changes in pressure and temperature, phase changes, and the evolution of an expanding (and structurally weak) gas zone can significantly alter the distribution of loads in the sediments. The corresponding changes in the local stress and strain fields can result in substantial changes in the hydrologic, thermal and geomechanical properties of the system, displacement, and potentially failure.

Geologic Framework of the 2005 Keathley Canyon Geologic Framework of the 2005 Keathley Canyon Gas Hydrate Research Well, Northern Gulf of Mexico Authors: D.R. Hutchinson, P.E. Hart, T.S. Collett, K.M. Edwards, and D.C. Twichell, U.S. Geological Survey, and F. Snyder, WesternGeco-Schlumberger. Venue: American Geophysical UnionÂ’s 2007 Joint Assembly, Acapulco, Mexico, May 22-25, 2007 (http://www.agu.org/meetings/ja07/ [external site]). Abstract: The project was located in the Casey Basin in the northern Gulf of Mexico at 1,335 m water depth. A grid of 2-D high-resolution multichannel seismic lines around the drill sites, targeted for imaging depths down to at least 1,000 m subbottom, reveals multiple disconformities that bound seven mappable seismic stratigraphic units. A major disconformity in the middle of the units stands out for its angular baselapping geometry. From the seismic and drilling data, three episodes of sedimentary deposition and deformation are inferred. The oldest episode consists of fine-grained muds deposited during a period of relative stability in the basin (Units E, F, and G). A second episode (Units C and D) consists of large vertical displacements associated with infilling and ponding of sediment. This second interval corresponds with intercalated fine and coarse-grained material in the drill hole, which sampled the thin edges of much thicker units. The final episode (Units A and B) occurred during much-subdued vertical displacement. Hemipelagic drape (Unit A) characterizes the modern seafloor deposits. The basin is mostly filled. Its sill is part of a subsiding graben that is only 10-20 m shallower than the deepest point in the basin, indicating that gravity-driven transport would mostly bypass the basin. Contemporary faulting along the basin margins has selectively reactivated an older group of faults. The intercalated sand and mud deposits of Units C and D are tentatively correlated with late Pleistocene deposition derived from the western shelf-edge delta/depocenter of the Mississippi River, which was probably most active from 320 ka to 70 ka (Winker and Booth, 2000). Gas hydrate occurs within near-vertical fractures in Units E and F of the oldest episode. The presence of sand within the gas hydrate stability zone is not sufficient to concentrate gas hydrate, even though dispersed gas hydrate occurs deeper in the fractured mud/clay-rich sections of Units E and F.

A Grain-Scale Coupled Model of Multiphase Fluid Flow and Sediment Mechanics A Grain-Scale Coupled Model of Multiphase Fluid Flow and Sediment Mechanics A Grain-Scale Coupled Model of Multiphase Fluid Flow and Sediment Mechanics – Application to Methane Hydrates in Natural Systems Authors: Antone K. Jain and Ruben Juanes Venue: American Geophysical Union Fall Meeting, San Francisco, CA, December 15-19, 2008 – Special Session H06: Particle Tracking Simulation of Fluid Flow and Mass Transport. http://www.agu.org/meetings/fm08/ Abstract: A discrete element model is presented for the simulation, at the grain scale, of gas migration in brine-saturated deformable media. The model rigorously accounts for the presence of two fluids in the pore space by incorporating grain forces due to pore fluid pressures, and surface tension between fluids. The coupled model permits investigating an essential process that takes place at the base of the hydrate stability zone: the upward migration of methane in its own free gas phase. The ways in which gas migration may take place were elucidated: (1) by capillary invasion in a rigid-like medium; and (2) by initiation and propagation of a fracture. Results indicate that the main factor controlling the mode of gas transport in the sediment is the grain size, and that coarse-grain sediments favor capillary invasion, whereas fracturing dominates in fine-grain media. The results have important implications for understanding hydrates in natural systems. The results predict that, in fine sediments, hydrate will likely form in veins that follow a fracture-network pattern, and the hydrate concentration in this type of accumulations will likely be quite low. In coarse sediments, the buoyant methane gas is likely to invade the pore space more uniformly, in a process akin to invasion percolation, and the overall pore occupancy is likely to be much higher than for a fracture-dominated regime. These implications are consistent with field observations of methane hydrates in natural

This sample became the impetus for the first United States national research and development program dedicated to gas hydrates. By the mid 1990s, it was widely accepted that gas hydrates represented a vast storehouse of gas. Recognizing the importance of gas hydrate research and the need for coordinated efforts, Congress and the President of the United States enacted Public Law 106-193, the Methane Hydrate Research and Development Act of 2000. Authorization for this program was extended to 2010 as part of the Energy Policy Act of 2005. Many of the current gas hydrate projects in the United States are conducted within this program, which is administered by the U. S. Department of Energy in collaboration with six other U.S. federal agencies, and conducted in partnership with private industry, academic institutions, and DOEÂ’s National Laboratories. In addition, other U.S. federal agencies conduct significant self-directed gas hydrate research; most notably the gas hydrate resource assessment activities conducted by U.S. Department of Interior agencies (the U.S. Geological Survey and the Minerals Management Service).

Morrow, Snuller Price, and Margaret S. Torn Journal Science Volume 335 Start Page 53 Issue 6064 Pagination 53-59 Date Published 01/2012 Abstract Several states and countries have adopted targets for deep reductions in greenhouse gas emissions by 2050, but there has been little physically realistic modeling of the energy and economic transformations required. We analyzed the infrastructure and technology path required to meet California's goal of an 80% reduction below 1990 levels, using detailed modeling of infrastructure stocks, resource constraints, and electricity system operability. We found that technically feasible levels of energy efficiency and decarbonized energy supply alone are not sufficient; widespread electrification of transportation and other sectors is required. Decarbonized electricity would become the dominant form of energy supply, posing challenges and opportunities for economic growth and climate policy. This transformation demands technologies that are not yet commercialized, as well as coordination of investment, technology development, and infrastructure deployment.

Chapter 10.2 - Heat-Resistant Coating Technology for Gas Turbines  

Science Journals Connector (OSTI)

The operating temperature of gas turbines in the 1990s and later has been notably high in order to achieve high-efficiency power-generating plants by combining these gas turbines and steam turbines. Such high operating temperatures has been made possible with the development of heat-resistant superalloys forming turbine hot parts, as well as advances made in heat-resistant coating technology and cooling technology. For 1500 °C-class gas turbines, the adoption of single-crystal Ni-based superalloy blades and ceramic thermal barrier coatings is indispensable, and additionally, steam-cooled technology should be employed. In particular, thermal barrier coating (TBC) technology is recognized as important. Therefore, this paper reviews the trend of development of heat-resistant coating technology for gas turbines by paying attention to coating processes and evaluation. The paper also reviews the trend of development and standardization of heat-resistance evaluation test methods for coatings, because such evaluation test methods are indispensable for the development of heat-resistant coating technology.

Jain and Ruben Juanes Venue: American Geophysical Union Fall Meeting, San Francisco, CA, December 15-19, 2008 – Special Session H06: Particle Tracking Simulation of Fluid Flow and Mass Transport. http://www.agu.org/meetings/fm08/ Abstract: Two competing processes were simulated, capillary invasion and fracture opening, by which free methane gas penetrates the Hydrate Stability Zone (HSZ). In situ conditions were predicted in which the methane propagates fractures and flows all the way through the HSZ and into the ocean, bypassing hydrate formation. In the fully coupled model, the discrete element method was used to simulate the sediment mechanics, and pore fluid pressures and surface tension between the gas and brine were accounted for by incorporating additional sets of pressure forces and adhesion forces. Results indicate that given enough capillary pressure, the main factor controlling the mode of gas transport is the grain size, and show that coarse-grain sediments favor capillary invasion and widespread hydrate formation, whereas fracturing dominates in fine-grain sediments. The fracturing threshold was calculated as a function of grain size, capillary pressure, and seafloor depth, and place these results in the context of naturally-occurring hydrate

Capillarity-controlled displacements in sediments with moveable grains Capillarity-controlled displacements in sediments with moveable grains Capillarity-controlled displacements in sediments with moveable grains: Implications for growth of methane hydrates Authors: Maša Prodanovic (speaker), Steven L. Bryant Venue: SPE Annual Technical Conference and Exhibition, Denver, Colorado, 21-24 September, 2008. http://www.spe.org [external site]. Abstract: We consider immiscible displacements when fluid/fluid interfaces are controlled by capillary forces. The progressive quasistatic (PQS) algorithm based on the level set method readily determines the geometry of these interfaces at the pore level. Capillary pressure generally exerts a net force on grains supporting an interface. We extend PQS to implement a kinematic model of grain displacement in response to that force. We examine the changes in the drainage curve caused by this coupling. We compute the interfacial area associated with the bulk water phase, anticipating preferential growth of methane hydrate there. Gas invasion of sediments is one mechanism by which methane hydrates are believed to form. In unconsolidated ocean sediments the capillary pressure exerted by an accumulated gas phase below the hydrate stability zone can be large enough to move grains apart. This motion alters the pore throat sizes which control subsequent drainage of the sediment. A model for the dynamics of this process is useful for assessing the competition between drainage (controlled by capillary forces) and fracturing (controlled by pore pressure and earth stresses). This in turn provides insight into the possible growth habits within the hydrate stability zone. When grains can move in response to net force exerted by the gas phase, small variations in an otherwise uniform distribution of pore throat sizes quickly lead to self-reinforcing, focused channels of gas phase. In contrast to behavior in stationary grains, the drainage curve exhibits no clear percolation threshold. Displacements in materials with broad throat size distributions also exhibit self-reinforcing channels. Behind the leading edge of the displacement front, the net force exerted on the grains tends to push them together. This effectively seals off these regions from subsequent invasion. Thus hydrate growth tends to be localized along the channel of displaced grains. This is the first quantitative grain-scale study of the drainage behavior when grains can move in response to invasion events. The coupling leads to qualitatively different displacement patterns. The method presented for studying this behavior is applicable to any granular material and to other applications, such as sand production.

De-Watering of Hunton Reservoirs De-Watering of Hunton Reservoirs De-Watering of Hunton Reservoirs Author: Mohan Kelkar, University of Tulsa, Tulsa, OK. Venue: Tulsa Association of Petroleum Landmen meeting in Tulsa, OK, April 19, 2007 (http://www.landman.org [external site]). Abstract: The Hunton reservoir in Oklahoma represents one of the largest discoveries in Oklahoma in recent history. Since 1995, several Hunton reservoir fields have been exploited by various operators. The principle behind this exploitation remains the same: The wells produce large quantities of water, and along with it, significant quantities of natural gas and sometimes oil. Examination of various fields producing from the Hunton reservoir indicates that the economic success from these fields is not uniform. Some fields produce significant quantities of oil, whereas some fields only produce gas. In some fields, horizontal wells work best, whereas in some other fields, vertical wells do a good job. The water production from the fields ranges from as low as few hundred barrels per day to several thousand barrels per day. In this paper, we present the results from various fields to indicate the parameters needed in a Hunton field to make it economically successful. We restrict our evaluation to parameters that can be easily measured or are readily available. These include log data (gamma ray, resistivity, neutron, and density), initial potential data, production data (oil, gas, and water—if available) and well configuration (vertical or horizontal). By analyzing the recovery of oil and gas according to various reservoir parameters, we developed a methodology for predicting the future success of the field. For example, a clear relationship exists between porosity of the rock and initial hydrocarbon saturation: The higher the oil saturation, the better the recovery factor. Initial potential is critical in determining possible recovery. Horizontal wells cost 1.5 to 2 times more than vertical wells and may not provide the additional recovery to justify the costs. The Hunton formation is extensive in Oklahoma. If we want to extend the success of some of the fields to other areas, we need clear guidelines in terms of what is needed to exploit those fields. This paper provides some of those guidelines based on the examination of the currently producing fields.

Fluid Flow through Heterogeneous Methane-Hydrate Bearing Sand Fluid Flow through Heterogeneous Methane-Hydrate Bearing Sand Fluid Flow through Heterogeneous Methane-Hydrate Bearing Sand: Observations Using X-Ray CT Scanning Authors: Yongkoo Seol and Timothy J. Kneafsey Venue: 6th International Conference on Gas Hydrates (ICGH 2008), Vancouver, British Columbia, CANADA, July 6-10, 2008. http://www.icgh.org/ [external site] Abstract: The effects of porous medium heterogeneity on methane hydrate formation, water flow through the heterogeneous hydrate-bearing sand, and hydrate dissociation were observed in an experiment using a heterogeneous sand column with prescribed heterogeneities. X-ray computed tomography (CT) was used to monitor saturation changes in water, gas, and hydrate during hydrate formation, water flow, and hydrate dissociation. The sand column was packed in several segments having vertical and horizontal layers with two distinct grain-size sands. The CT images showed that as hydrate formed, the water and hydrate saturations were dynamically redistributed by variations in capillary strength of the medium (the tendency for a material to imbibe water), which changed with the presence and saturation of hydrate. Water preferentially flowed through fine sand near higher hydrate-saturation regions where the capillary strength was elevated relative to the lower hydrate saturation regions. Hydrate dissociation initiated by depressurization varied with different grain sizes and hydrate saturations.

Saline Water Disposal in the Uinta Basin, Utah Saline Water Disposal in the Uinta Basin, Utah Saline Water Disposal in the Uinta Basin, Utah Authors: Michael D. Vanden Berg, Stephanie Carney, Michael D. Laine, Craig D. Morgan, Utah Geological Survey; and Paul B. Anderson, consulting geologist. Venue: Poster Session: Responsible Development, Sustainability, and Climate Science—Groundwater and Site Remediation, June 9, 2009, American Association of Petroleum Geologists annual meeting, Denver, CO, June 7 to 10, 2009. http://www.aapg.org/denver/ [external site] Abstract: Saline water disposal is the single most pressing issue with regard to increasing petroleum and natural gas production in the Uinta Basin of Utah. Conventional oil and gas fields in the basin provide 67% of Utah’s total crude oil production and 71% of Utah’s total natural gas, the latter of which has increased 175% in the last 10 years. As petroleum production increases, so does saline water production, creating an increased need for economic and environmentally responsible disposal plans. Current water disposal wells are near capacity, and permitting for new wells is being delayed because of a lack of technical data regarding potential disposal aquifers and questions concerning contamination of fresh water sources. Many Uinta Basin operators claim that petroleum and natural gas production cannot reach its full potential until a suitable, long-term saline water disposal solution is determined. Researchers have begun efforts to re-map the base of the moderately saline aquifer within the Uinta Basin using more robust data and more sophisticated GIS techniques than previous efforts. Below this base, they believe that saline water can be injected without damage to the overlying freshwater reservoirs. Water chemistry data are being collected from wells of operators and governmental agencies. These ground-truth data are supplemented with water chemistry information calculated from geophysical logs. In addition to the new GIS-based map, the researchers are constructing cross sections showing the stratigraphic position of the moderately saline to very saline transition and its relationship to potential seals and disposal zones in the Uinta Basin. A potentially suitable disposal zone for large volume saline water disposal is the fresh to slightly saline Bird’s-Nest aquifer. This aquifer is located in the oil shale zone of the Green River formation’s Parachute Creek member and is 200 to 300 ft above the kerogen-rich Mahogany zone. A significant concern is that saline water disposal into the Bird’s-Nest by conventional gas producers may hinder oil shale development by creating unforeseen economic and technical hurdles. With increased saline water disposal, the water quality in the Bird’s-Nest could degrade and create additional water disposal problems for oil shale development companies. Researchers have examined this aquifer in outcrop, core, and geophysical logs and have gained a better understanding of its areal extent, thickness, and zones of differing water chemistry

Advanced separation technology for flue gas cleanup. Topical report  

SciTech Connect

The objective of this work is to develop a novel system for regenerable SO{sub 2} and NO{sub x} scrubbing of flue gas that focuses on (1) a novel method for regenerating spent SO{sub 2} scrubbing liquor and (2) novel chemistry for reversible absorption of NO{sub x}. In addition, high efficiency hollow fiber contactors (HFC) are proposed as the devices for scrubbing the SO{sub 2} and NO{sub x} from the flue gas. The system will be designed to remove more than 95% of the SO{sub 2} and more than 75% of the NO{sub x} from flue gases typical of pulverized coal-fired power plants at a cost that is at least 20% less than combined wet limestone scrubbing of SO{sub x} and selective catalytic reduction of NO{sub x}. The process will generate only marketable by-products. Our approach is to reduce the capital cost by using high-efficiency hollow fiber devices for absorbing and desorbing the SO{sub 2} and NO{sub x}. We will also introduce new process chemistry to minimize traditionally well-known problems with SO{sub 2} and NO{sub x} absorption and desorption. Our novel chemistry for scrubbing NO{sub x} will consist of water-soluble phthalocyanine compounds invented by SRI as well as polymeric forms of Fe{sup ++} complexes similar to traditional NO{sub x} scrubbing media. The final novelty of our approach is the arrangement of the absorbers in cassette (stackable) form so that the NO{sub x} absorber can be on top of the SO{sub x} absorber. This arrangement is possible only because of the high efficiency of the hollow fiber scrubbing devices, as indicated by our preliminary laboratory data. This arrangement makes it possible for the SO{sub 2} and NO{sub x} scrubbing chambers to be separate without incurring the large ducting and gas pressure drop costs necessary if a second conventional absorber vessel were used. Because we have separate scrubbers, we will have separate liquor loops and simplify the chemical complexity of simultaneous SO{sub 2}/NO{sub x} scrubbing.

Environmental trends in Asia are accelerating the introduction of clean coal technologies and natural gas  

SciTech Connect

This paper examines the changing energy mix for Asia to 2020, and impacts of increased coal consumption on Asia`s share of world SO{sub 2} and CO{sub 2} emissions. Stricter SO{sub 2} emissions laws are summarized for eight Asian economies along with implications for fuel and technology choices. The paper compares the economics of different technologies for coal and natural gas in 1997 and in 2007. Trends toward introducing clean coal technologies and the use of natural gas will accelerate in response to tighter environmental standards by 2000. The most important coal conversion technology for Asia, particularly China, in the long term is likely to be integrated gasification combined-cycle (IGCC), but only under the assumption of multiple products.

Integrated Underground Gas Storage of CO2 and CH4 to Decarbonise the “Power-to-gas-to-gas-to-power” Technology  

Science Journals Connector (OSTI)

Abstract Excess energy produced from renewables can be stored and reused via the “power-to-gas-to-power” (PGP) technology. We present an innovative idea which represents a decarbonised extension of PGP based on a closed carbon cycle. Our show case for the cities Potsdam and Brandenburg/Havel (Germany) outlines an overall efficiency for the entire process chain of 28% with total costs of electricity of 20 eurocents/kWh. If existing locations in Europe, where natural gas storage in porous formations is performed, were to be extended by CO2 storage sites, a significant quantity of wind and solar energy could be stored economically as methane.

Delivery Reliability for Natural Gas--Inspection Technologies  

SciTech Connect

The Remote Field Eddy Current (RFEC) technique is ideal for inspecting unpiggable pipelines because all of its components can be made smaller than the diameter of the pipe to be inspected. For these reasons, RFEC was selected as a technology to be integrated with the Explorer II robotic platform for unpiggable pipeline inspections. The research work is a continuation of a prior DOE-NETL project but is now directed towards a seamless integration with the robot. The laboratory set-up has been improved and data collection is nearly autonomous. With the improved collections speeds, GTI has been able to test more variables. Tests have been run on 6-inch and 12-inch seamless and seam-welded pipes. Testing on the 6-inch pipes have included using five exciter coils, each of a different geometry. Two types of sensor coils have been tested. With a focus on preparing the technology for use on the Explorer II, improvements in power consumption have proved successful. Tests with metal components have been performed to check for interference with the electromagnetic field. The results of these tests indicate RFEC will produce quality inspections while on the robot. GTI has also been testing manufactured detection boards currently used for boiler tube inspections. These boards are appropriately compact for use on the Explorer II robot and are able to detect defects at the speed of robot travel. In addition to advanced sensor development, GTI has participated in sensor/platform definition and module design activities. Mechanical constraints, power requirements, limited control and communication protocols, and potential busses and connectors have been addressed. GTI has conducted a proper design process to produce a sound design for the RFEC components to fit into two modules. The remaining work to be performed in the design of the sensor module is packaging and strengthening.

Enabling Technology for Monitoring & Predicting Gas Turbine Health & Performance in IGCC Powerplants  

SciTech Connect

The ''Enabling & Information Technology To Increase RAM for Advanced Powerplants'' program, by DOE request, was re-directed, de-scoped to two tasks, shortened to a 2-year period of performance, and refocused to develop, validate and accelerate the commercial use of enabling materials technologies and sensors for coal/IGCC powerplants. The new program was re-titled ''Enabling Technology for Monitoring & Predicting Gas Turbine Health & Performance in IGCC Powerplants''. This final report summarizes the work accomplished from March 1, 2003 to March 31, 2004 on the four original tasks, and the work accomplished from April 1, 2004 to July 30, 2005 on the two re-directed tasks. The program Tasks are summarized below: Task 1--IGCC Environmental Impact on high Temperature Materials: The first task was refocused to address IGCC environmental impacts on high temperature materials used in gas turbines. This task screened material performance and quantified the effects of high temperature erosion and corrosion of hot gas path materials in coal/IGCC applications. The materials of interest included those in current service as well as advanced, high-performance alloys and coatings. Task 2--Material In-Service Health Monitoring: The second task was reduced in scope to demonstrate new technologies to determine the inservice health of advanced technology coal/IGCC powerplants. The task focused on two critical sensing needs for advanced coal/IGCC gas turbines: (1) Fuel Quality Sensor to rapidly determine the fuel heating value for more precise control of the gas turbine, and detection of fuel impurities that could lead to rapid component degradation. (2) Infra-Red Pyrometer to continuously measure the temperature of gas turbine buckets, nozzles, and combustor hardware. Task 3--Advanced Methods for Combustion Monitoring and Control: The third task was originally to develop and validate advanced monitoring and control methods for coal/IGCC gas turbine combustion systems. This task was refocused to address pre-mixed combustion phenomenon for IGCC applications. The work effort on this task was shifted to another joint GE Energy/DOE-NETL program investigation, High Hydrogen Pre-mixer Designs, as of April 1, 2004. Task 4--Information Technology (IT) Integration: The fourth task was originally to demonstrate Information Technology (IT) tools for advanced technology coal/IGCC powerplant condition assessment and condition based maintenance. The task focused on development of GateCycle. software to model complete-plant IGCC systems, and the Universal On-Site Monitor (UOSM) to collect and integrate data from multiple condition monitoring applications at a power plant. The work on this task was stopped as of April 1, 2004.

Super-Cement for Annular Seal & Long-Term Integrity in Deep, Hot Wells Super-Cement for Annular Seal & Long-Term Integrity in Deep, Hot Wells Super-Cement for Annular Seal & Long-Term Integrity in Deep, Hot Wells Authors: Fred Sabins, Kevin Edgely, and Larry Watters, CSI Technologies, LLC, Houston, TX. Venue: 2007 Drilling Engineering Association Workshop, Moody Gardens Hotel, Galveston, TX, June 19-20, 2007 (http://www.dea-global.org) [external site]). Abstract: Successful laboratory and field testing of Ultra-Seal® R and Pre-Stressed Cement will be presented. The application of these materials can dramatically reduce the costs of re-establishing annular seal integrity in deep, hot wells, thereby significantly lowering life-cycle well costs. CSI Technologies chose two cement types for further field testing in the third phase of the project to develop a “supercement” for work in high-temperature/high-pressure (HT/HP) wells. HT/HP wells often encounter problems with isolation of production zones due to cement failures. This can result in expensive repair jobs and costly shut-ins of high-volume wells. CSI determined that resin and magnesium oxide cements showed very good mechanical properties and bonding characteristics and are controllable at HT/HP conditions. The resin cement has been used successfully in more than 50 field plugging jobs and in one HT/HP squeeze job. CSI developed a second supercement formulation that is Portland cement- based and functions by generating substantial expansion during the curing process. This material functions in the confined wellbore environment by developing significant cement matrix compressive stress during cure, resulting in a compressive pre-load. In practice, the compressive pre-load functions to elevate the effective tensile strength of the material because the compressive stress must be relieved before the material can experience tensile stress. Additionally, the pre-load functions to keep the material tightly bound to the wellbore tubulars, thereby reducing the tendency of repeated stress cycles to form a microannulus.

Updated Results from Deep Trek High-Temperature Electronics Development Programs Updated Results from Deep Trek High-Temperature Electronics Development Programs Updated Results from Deep Trek High-Temperature Electronics Development Programs Author: Bruce W. Ohme, Honeywell Inc., Plymouth, MN. Venue: HITEN 2007 (High-Temperature Electronics Network conference), St. Catherine’s College, Oxford, U.K., September 17–19, 2007, (http://science24.com/event/hiten2007 [external site]). Abstract: Electronics are used in modern oil and gas exploration to collect, log, and/or process data such as heading and inclination, weight on the bit, vibration, seismic/acoustic response, temperature, pressure, radiation, and resistivity of the strata. High-temperature electronics are needed that can operate reliably in deep-well conditions (up to 250oC). Under its Deep Trek program, the U.S. Department of Energy has funded two projects led by Honeywell. The first project, launched in 2003 and being completed this year, established a production-level integrated circuit manufacturing process, components, and design tools specifically targeting high-temperature environments (up to 250oC). The second project, launched in 2006 and expected to be completed in 2008, will develop rugged packaging suitable for downhole shock and vibration levels that will be used to house and demonstrate components developed in the earlier project. This paper will describe updated results from both of these projects, including previously unreported results obtained from prototype testing of a high-resolution analog-to-digital converter (ADC); a high-temperature, single-poly, floating-gate EEPROM (electrically erasable programmable read-only memory); and a 12-bit, successive-approximation ADC. Also, a multi-chip module being developed as a complete downhole processing unit will be discussed

Estimating Fracture Reorientation Due to Fluid Injection/Production Estimating Fracture Reorientation Due to Fluid Injection/Production Estimating Fracture Reorientation Due to Fluid Injection/Production Authors: Zongyu Zhai and Mukul M. Sharma, University of Texas at Austin. Venue: Society of Petroleum Engineers’ Production and Operations Symposium, Oklahoma City, OK, April 1–3, 2007 (http://www.spe.org/ [external site]). Abstract: The injection or production of large volumes of fluid into or from a reservoir can result in significant changes to the effective in-situ stress distributions. Field evidence of this has been provided in the past by mapping refracturing treatments in tight gas sands and microseismic monitoring of injection wells in waterflooded reservoirs. A poro-elastic model is presented to show how the extent of fracture reorientation can be estimated under different conditions of fluid injection and production. The extent of fracture reorientation is a function of the in-situ stresses, the mechanical properties of the rock, and the pore pressure gradients. In reservoirs where the pore pressure gradients are complicated due to multiple injection and production wells, fracture reorientation is sensitive to the net pore-pressure gradients. Fractures tend to reorient themselves towards the injection wells and away from production wells, if the pressure gradients are comparable to the in-situ stress contrast. While far-field principal stress orientations are impacted only by in-situ stresses and pore-pressure gradients, near-wellbore in-situ stress orientation is also impacted by the hoop stress and the wellbore pressure. These can have a significant effect on near-wellbore fracture reorientation. The results of our model are compared with field observations obtained from microseismic monitoring of water injection wells. The implications of the results to refracturing operations and candidate well selection are discussed.

Technology on In-Situ Gas Generation to Recover Residual Oil Reserves  

SciTech Connect

This final technical report covers the period October 1, 1995 to February 29, 2008. This chapter begins with an overview of the history of Enhanced Oil Recovery techniques and specifically, CO2 flood. Subsequent chapters conform to the manner consistent with the Activities, Tasks, and Sub-tasks of the project as originally provided in Exhibit C1 in the Project Management Plan dated September 20, 1995. These chapters summarize the objectives, status and conclusions of the major project activities performed during the project period. The report concludes by describing technology transfer activities stemming from the project and providing a reference list of all publications of original research work generated by the project team or by others regarding this project. The overall objective of this project was a final research and development in the United States a technology that was developed at the Institute for Geology and Development of Fossil Fuels in Moscow, Russia. Before the technology can be convincingly adopted by United States oil and gas producers, the laboratory research was conducted at Mew Mexico Institute of Mining and Technology. The experimental studies were conducted to measure the volume and the pressure of the CO{sub 2} gas generated according to the new Russian technology. Two experimental devices were designed, built and used at New Mexico Tech facilities for these purposes. The designed setup allowed initiating and controlling the reaction between the 'gas-yielding' (GY) and 'gas-forming' (GF) agents proposed by Russian technology. The temperature was controlled, and the generated gas pressure and volume were recorded during the reaction process. Additionally, the effect of surfactant addition on the effectiveness of the process was studied. An alternative GY reactant was tested in order to increase the efficiency of the CO2 gas generation process. The slim tube and the core flood experimental studies were conducted to define the sweep efficiency of the in-situ generated CO{sub 2} gas. A set of core flood experiments were conducted to define effect of surfactant on recovery efficiency. The results demonstrated obvious advantages of the foamy system over the brine solution in order to achieve higher sweep efficiency and recovery coefficient. It is shown that a slug injection is not an efficient method for mixing GY and GF solutions and it can't generate considerable gas inside the slim-tube.

(speaker, Oregon State University), Hangsterfer, A., Brodie, E., Daly, R., Holland, M., Briggs, B., Carini, P., Torres, M., Kastner, M., Long, P., Schaef, H., Delwiche, M., Winters, W., and Riedel, M. Venue: American Geophysical Union’s fall meeting in San Francisco, CA, December 10–14, 2007 (http://www.agu.org/meetings/fm07/ [external site]). Abstract: Deep subseafloor sediments with high concentrations of organic carbon and microbially generated methane contain microbial communities that play an important role in the biogeochemical cycling of carbon. However, there remains a limited understanding of the fine (centimeter)-scale sediment properties (e.g., grain size, presence/absence of hydrates) that determine key microbial attributes in deep marine sediments. This project’s objective is to determine the quantity, diversity, and distribution of microbial communities in the context of abiotic properties in gas-rich marine sediments. DNA was extracted from deep marine sediments cored from various continental shelf locations, including offshore India and the Cascadia Margin. Abiotic characterization of the same sediments included grain size analysis, chloride concentrations in sediment pore waters, and presence of hydrates in the sediments as determined by thermal anomalies. As in past studies of such systems, most of the samples yielded low levels of DNA (0.3-1.5 ng/g of sediment). Bacterial DNA appeared to be more easily amplified than archaeal DNA. Initial attempts to amplify DNA using primers specific for the methanogen functional gene, methyl-CoM-reductase, were unsuccessful. Infrequently, cores from relatively shallow sediments (e.g., 0.5 mbsf Leg 204, 1251B-1H) from central (Hydrate Ridge) and northern (offshore Vancouver Island) Cascadia and from India’s eastern margin contained macroscopically visible, pigmented biofilms. One of these biofilms was composed of high concentrations of cell clusters when viewed microscopically. The predominant cells in the Hydrate Ridge biofilm were large (ca. 10 um) cocci, and preliminary characterization of the 16S rDNA amplified and sequenced from this biofilm suggests the prevalence of a microbe with 97% similarity to mycobacteria. These discrete biofilm communities appear to be distinctive relative to the normally sparse distribution of cells in the sediments. By determining how the abiotic properties of deep marine sediments control the numbers and distribution of microbial communities that process organic matter, project researchers hope to provide better parameters for computational models that describe carbon cycling in these systems.

Novel Applications for Biogeophysics: Prospects for Detecting Key Subseafloor Geomicrobiological Processes or Habitats Novel Applications for Biogeophysics: Prospects for Detecting Key Subseafloor Geomicrobiological Processes or Habitats Novel Applications for Biogeophysics: Prospects for Detecting Key Subseafloor Geomicrobiological Processes or Habitats Authors: Rick Colwell, Oregon State University, and Dimitris Ntarlagiannis, Rutgers University. Venue: American Geophysical UnionÂ’s 2007 Joint Assembly, Acapulco Mexico, May 21-25, 2007 (http://www.agu.org/ [external site]). Abstract: The new subdiscipline of biogeophysics has focused mostly on the geophysical signatures of microbial processes in contaminated subsurface environments usually undergoing remediation. However, the use of biogeophysics to examine the biogeochemistry of marine sediments has not yet been well integrated into conceptual models that describe subseafloor processes. Current examples of geophysical measurements that have been used to detect geomicrobiological processes or infer their location in the seafloor include sound surveillance system (SOSUS)-derived data that detect seafloor eruptive events, deep and shallow cross-sectional seismic surveys that determine the presence of hydraulically conductive zones or gas-bearing sediments (e.g., bottom-simulating reflectors or bubble-rich strata), and thermal profiles. One possible area for innovative biogeophysical characterization of the seafloor involves determining the depth of the sulfate-methane interface (SMI) in locations where sulfate diffuses from the seawater and methane emanates from subsurface strata. The SMI demarcates a stratum where microbially driven anaerobic methane oxidation (AMO) is dependent upon methane as an electron donor and sulfate as an electron acceptor. AMO is carried out by a recently defined, unique consortium of microbes that metabolically temper the flux of methane into the overlying seawater. The depth of the SMI is, respectively, shallow or deep according to whether a high or low rate of methane flux occurs from the deep sediments. Presently, the SMI can only be determined by direct measurements of methane and sulfate concentrations in the interstitial waters or by molecular biological techniques that target the microbes responsible for creating the SMI. Both methods require collection and considerable analysis of sediment samples. Therefore, detection of the SMI by non-destructive methods would be advantageous. As a key biogeochemical threshold in marine sediments, the depth of the SMI defines methane charge in marine sediments, whether it is from dissolved methane or from methane hydrates. As such, a biogeophysical strategy for determining SMI depth would represent an important contribution to assessing methane charge with respect to climate change, sediment stability, or potential energy resources.

Benson, Colorado School of Mines, Golden, CO; and Claudia Rebne, Legacy Energy, Denver, CO. Venue: American Association of Petroleum Geologists/Rocky Mountain Section Annual Meeting in Snowbird, UT, October 7-9, 2007. Abstract: A 3D9C survey was carried out over a 6 square mile portion of the Roadrunner and Towaoc fields on the Ute Mountain Ute reservation in southwestern Colorado. This survey was jointly funded by DOE and the Southern Ute tribeÂ’s Red Willow Corporation to promote development of Ismay algal mound plays in the Paradox Basin within Ute Mountain Tribal lands and elsewhere in the Paradox Basin. Multicomponent data were utilized to better delineate the external mound geometry as well as to estimate internal mound reservoir parameters such as matrix permeability, saturation, and porosity. Simple cross-plotting of various multicomponent attributes against reservoir properties did not provide the desired predictive accuracy, in part due to sub-optimal frequency content in components derived from the shear wave data. However, a multivariate statistical analysis greatly improved the predictive accuracy. These multivariate regressions were then used to prescribe reservoir properties for a static reservoir model, which in turn formed the basis for a dynamic reservoir simulation model of the project area to assess the usefulness of the multivariate relations developed. This poster presentation will illustrate the workflow used to carry out the multivariate modeling, key maps of the reservoir properties that were derived, the static model, and results from the dynamic simulation used to assess the usefulness of the approach. Results from wells drilled based on the seismic data also will be presented.

Detailed Imaging of Facies and Fluid Distribution Within Carbonate Oil Reservoirs Detailed Imaging of Facies and Fluid Distribution Within Carbonate Oil Reservoirs Crosswell Seismic Amplitude-Versus-Offset for Detailed Imaging of Facies and Fluid Distribution Within Carbonate Oil Reservoirs Authors: Sean P. Trisch, Wayne D. Pennington, and Roger Turpening, Michigan Technological University, Houghton, MI. Venue: Seismological Society of America’s annual meeting in Waikaloa, Kona, HI., April 11–13, 2007 Abstract: Imaging of the Earth’s crust is increasingly being accomplished through the use of borehole-based sensors. Experience gained in recent crosswell seismic surveys may assist endeavors to image the near-borehole environment near plate boundaries or other places of scientific interest. A high-resolution crosswell seismic data set was collected over a Silurian (Niagaran) reef in Michigan’s Lower Peninsula. The survey was optimized for both reflection imaging purposes and the gathering of a wide range of incidence angles. The reflection image was intended to aid in interpretation of the reef structure at a level of detail never before possible with seismic methods. The survey was also conducted to maximize data available for study of the dependence of amplitudes with angle-of-incidence. Prestack angle data were processed to half-degree intervals and utilized for enhanced interpretation of the seismic image through partial stacks and through amplitude variation with angle (AVA) analyses. Frequencies as high as 3,000 Hz (the limit of the source sweep) were recorded, with a predominant signal at about 2,000 Hz; the well separation was 600 m, and the target reef is at 1,400–1,525 m depth. Many of the interfaces present within the area have small reflection amplitudes at narrow angles that increase substantially near the critical angle. Analyses were performed on various interfaces in the seismic section to compare with Zoeppritz-equation solutions, using rock data acquired through an extensive library of seismic and well logging data available for the area. These models were then compared with the actual AVA character acquired at the interface and matched as closely as possible. Through this analysis and match process, various rock property estimates were inferred or refined.

Characterization of oil and gas reservoirs and recovery technology deployment on Texas State Lands  

SciTech Connect

Texas State Lands oil and gas resources are estimated at 1.6 BSTB of remaining mobile oil, 2.1 BSTB, or residual oil, and nearly 10 Tcf of remaining gas. An integrated, detailed geologic and engineering characterization of Texas State Lands has created quantitative descriptions of the oil and gas reservoirs, resulting in delineation of untapped, bypassed compartments and zones of remaining oil and gas. On Texas State Lands, the knowledge gained from such interpretative, quantitative reservoir descriptions has been the basis for designing optimized recovery strategies, including well deepening, recompletions, workovers, targeted infill drilling, injection profile modification, and waterflood optimization. The State of Texas Advanced Resource Recovery program is currently evaluating oil and gas fields along the Gulf Coast (South Copano Bay and Umbrella Point fields) and in the Permian Basin (Keystone East, Ozona, Geraldine Ford and Ford West fields). The program is grounded in advanced reservoir characterization techniques that define the residence of unrecovered oil and gas remaining in select State Land reservoirs. Integral to the program is collaboration with operators in order to deploy advanced reservoir exploitation and management plans. These plans are made on the basis of a thorough understanding of internal reservoir architecture and its controls on remaining oil and gas distribution. Continued accurate, detailed Texas State Lands reservoir description and characterization will ensure deployment of the most current and economically viable recovery technologies and strategies available.

High-temperature turbine technology program. Turbine subsystem design report: Low-Btu gas  

SciTech Connect

The objective of the US Department of Energy High-Temperature Turbine Technology (DOE-HTTT) program is to bring to technology readiness a high-temperature (2600/sup 0/F to 3000/sup 0/F firing temperature) turbine within a 6- to 10-year duration, Phase II has addressed the performance of component design and technology testing in critical areas to confirm the design concepts identified in the earlier Phase I program. Based on the testing and support studies completed under Phase II, this report describes the updated turbine subsystem design for a coal-derived gas fuel (low-Btu gas) operation at 2600/sup 0/F turbine firing temperature. A commercial IGCC plant configuration would contain four gas turbines. These gas turbines utilize an existing axial flow compressor from the GE product line MS6001 machine. A complete description of the Primary Reference Design-Overall Plant Design Description has been developed and has been documented. Trends in overall plant performance improvement at higher pressure ratio and higher firing temperature are shown. It should be noted that the effect of pressure ratio on efficiency is significally enhanced at higher firing temperatures. It is shown that any improvement in overall plant thermal efficiency reflects about the same level of gain in Cost of Electricity (COE). The IGCC concepts are shown to be competitive in both performance and cost at current and near-term gas turbine firing temperatures of 1985/sup 0/F to 2100/sup 0/F. The savings that can be accumulated over a thirty-year plant life for a water-cooled gas turbine in an IGCC plant as compared to a state-of-the-art coal-fired steam plant are estimated. A total of $500 million over the life of a 1000 MW plant is projected. Also, this IGCC power plant has significant environmental advantages over equivalent coal-fired steam power plants.

STATE OF THE ART AND FUTURE DEVELOPMENTS IN NATURAL GAS ENGINE TECHNOLOGIES  

SciTech Connect

Current, state of the art natural gas engines provide the lowest emission commercial technology for use in medium heavy duty vehicles. NOx emission levels are 25 to 50% lower than state of the art diesel engines and PM levels are 90% lower than non-filter equipped diesels. Yet, in common with diesel engines, natural gas engines are challenged to become even cleaner and more efficient to meet environmental and end-user demands. Cummins Westport is developing two streams of technologies to achieve these goals for medium-heavy and heavy-heavy duty applications. For medium-heavy duty applications, lowest possible emissions are sought on SI engines without significant increase in complexity and with improvements in efficiency and BMEP. The selected path builds on the capabilities of the CWI Plus technology and recent diesel engine advances in NOx controls, providing potential to reduce emissions to 2010 values in an accelerated manner and without the use of Selective Catalytic Reduction or NOx Storage and Reduction technology. For heavy-heavy duty applications where high torque and fuel economy are of prime concern, the Westport-Cycle{trademark} technology is in field trial. This technology incorporates High Pressure Direct Injection (HPDI{trademark}) of natural gas with a diesel pilot ignition source. Both fuels are delivered through a single, dual common rail injector. The operating cycle is entirely unthrottled and maintains the high compression ratio of a diesel engine. As a result of burning 95% natural gas rather than diesel fuel, NOx emissions are halved and PM is reduced by around 70%. High levels of EGR can be applied while maintaining high combustion efficiency, resulting in extremely low NOx potential. Some recent studies have indicated that DPF-equipped diesels emit less nanoparticles than some natural gas vehicles [1]. It must be understood that the ultrafine particles emitted from SI natural gas engines are generally accepted to consist predominantly of VOCs [2], and that lubricating oil is a major contributor. Fitting an oxidation catalyst to the natural gas engine leads to a reduction in nanoparticles emissions in comparison to engines without aftertreatment [2,3,4]. In 2001, the Cummins Westport Plus technology was introduced with the C Gas Plus engine, a popular choice for transit bus applications. This incorporates drive by wire, fully integrated, closed loop electronic controls and a standard oxidation catalyst for all applications. The B Gas Plus and the B Propane Plus engines, with application in shuttle and school buses were launched in 2002 and 2003. The gas-specific oxidation catalyst operates in concert with an optimized ring-pack and liner combination to reduce total particulate mass below 0.01g/bhphr, combat ultrafine particles and control VOC emissions.

A Comparative Economical Analysis of Technologies for CO2 Removal from Offshore Natural Gas  

Science Journals Connector (OSTI)

Abstract In the scenario of the Brazilian Pre-Salt fields, where associated Natural Gas (NG) shows high concentration of CO2, gas conditioning comes out as one of the main challenges. Among the possible capture technologies available, three alternatives stand out for CO2 sequestration: (A) gas permeation through membranes, (B) absorption columns using aqueous blends of ethanolamines and (C) application of hybrid - membrane modules in series with amine absorption and regeneration columns. The main objective of this work is to investigate the technical and economical feasibility of applying these three separation processes on offshore platforms, given the stringent constraints on footprint and equipment weight, and for minimizing NG production and transportation costs. The methodology involves: (i) development of cases based on the Brazilian Pre-Salt gas composition. NG streams with CO2 molar concentrations ranging from 8 to 18% are applied; (ii) Simulations of three process flowsheets, corresponding to each one of chosen technologies - A, B and C; (iii) Equipment sizing; and (iv) Analysis of economic performance through calculation of capital (CAPEX) and operational (OPEX) costs.

The Bakken Formation of the Williston Basin is a success story of horizontal drilling, fracturing, and completion technologies. The recent, highly productive oil field discoveries within the Bakken Formation did not come from venturing out into deep uncharted waters heretofore untapped by man, nor from blazing a trail into pristine environs never open to drilling before. Instead, success came from analysis of geologic data on a decades-old producing area, identification of uptapped resources, and application of the new drilling and completion technology necessary to exploit them.

Greenhouse gas emissions reduction in China by cleaner coal technology towards 2020  

Science Journals Connector (OSTI)

Abstract The Chinese energy system, a major CO2 emitter, relies heavily on fossil fuels, especially coal. Coal will continue to play a major role in the new installed power generation capacity in the future, which will cause unavoidable environmental problems. Clean coal technologies (CCTs) are essential for emissions reduction in the power sector. In general, \\{CCTs\\} cover coal upgrading, efficiency improvements, advanced technologies and zero emissions technologies. Besides these, \\{CCTs\\} also include other emissions reduction technologies and comprehensive utilization technologies in China. This paper review the complete life cycle modeling of CCTs. The advanced technologies include super-critical (super-C), ultra super-critical (USC) and integrated gasification combined cycle (IGCC). The results show that the higher efficiency technologies have lower potential impacts. Compared with the average level of power generation technology, CO2 emissions reduction is 6.4% for super-C, 37.4% for USC and 61.5% for IGCC. Four coal power scenarios are developed based on the assumption of potential investment power for \\{CCTs\\} in 2020, which are super-C, USC, USC and old low efficiency generation substitution by USC, IGCC and carbon capture and storage (CCS). The CO2 emissions intensity is 1.93 kg/kWh for super-C, 1.69 kg/kWh for USC, 1.59 kg/kWh for USC + replacement and 1.29 kg/kWh for IGCC + CCS. The CO2 emissions intensity was 1.95 kg/kWh in 2010, which had decreased 5.5% compared with the level in 2005. The energy structure is continuously being improved and optimized. The potential carbon reduction will be limited in the power system in 2020 by current commercial \\{CCTs\\} with the generation efficiency increase. The most impressive technology is IGCC with CCS which enables greenhouse gas reduction of 37.6% compared with the level in 2005.

Safety management in the Dutch oil and gas industry: the effect on the technological regime  

Science Journals Connector (OSTI)

This paper deals with the recent trend in Europe, from the formulation of detailed instructions and specifications with respect to the safety of industrial installations by governments, towards regulation on the level of safety management systems and risk analyses. The development sketched is studied with respect to the offshore oil and gas industry in the Netherlands. The government inspectorate responsible for this industry, the Staatstoezicht op de Mijnen (SodM), has, since the early 1990s, changed its approach from hardware-based inspections to inspection at the level of management systems. To assess the effects of this change in approach on industry practice the concept of ''technological regime'' is employed.

TECHNOLOGY TRANSFER TO U.S. INDEPENDENT OIL AND NATURAL GAS PRODUCERS  

SciTech Connect

The Petroleum Technology Transfer Council (PTTC) continued pursuing its mission of helping U.S. independent oil and natural gas producers make timely, informed technology decisions. PTTC's Board made a strategic decision to relocate the Headquarters (HQ) office from Washington, DC to Houston, Texas. Driving force behind relocation was to better connect with independent producers, but cost savings could also be realized. Relocation was accomplished in late December 2000, with the HQ office being fully operational by January 2001. Early indications are that the HQ relocation is, in fact, enabling better networking with senior executives of independents in the Houston oil community. New Board leadership, elected in March 2001, will continue to effectively guide PTTC.

Energy technology expert elicitations: An application to natural gas turbine efficiencies  

Science Journals Connector (OSTI)

Abstract Expert elicitations are critical tools for characterizing technological uncertainty, since historical data on technical progress may not provide a sufficient basis for forecasting future advances. The objectives of this paper are to describe the protocol and results for an expert elicitation on the future performance of gas-turbine-based technologies in the electric power sector and to discuss how these insights relate to the current elicitation literature in energy modeling. Elicitation results suggest that prospective efficiency gains are likely to be slower than historical trends; however, the assessed values are still appreciably higher than the efficiencies used in many energy models. The results also indicate that conducting face-to-face elicitations may be important for minimizing overconfidence and for critically examining reported values, especially when assessing non-central probabilities in the tails of a distribution.

the Performance of Class 2 and Class 3 Hydrate Deposits during Co-Production with Conventional Gas the Performance of Class 2 and Class 3 Hydrate Deposits during Co-Production with Conventional Gas The Performance of Class 2 and Class 3 Hydrate Deposits during Co-Production with Conventional Gas (OTC 19435) Authors: George J. Moridis (speaker), Matthew T. Reagan, and Keni Zhang Venue: 2008 Offshore Technology Conference, Houston, Texas, May 5-8, 2008 ( http://www.spe.org and http://www.smenet.org [external sites] ) Abstract: Recent numerical studies have provided strong indications that it is possible to produce large volumes of gas from natural hydrate deposits at high rates (in excess of 10 MMSCFD) for long times by depressurization-induced dissociation of hydrates. Of the various factors that can adversely affect the production potential of hydrates, low temperatures have one of the strongest negative impacts. These can be caused by low initial temperatures, increasing stability of the hydrate (as defined by the deviation between the temperature of the deposit and the equilibrium temperature at the reservoir pressure), and by an advanced stage of dissociation (a strongly endothermic reaction) when substantial amounts of hydrates remain. The reasons for the production decline include a reduction in the rate of the hydrate dissociation at lower temperatures and the evolution of flow restrictions in the vicinity of the well caused by the formation of hydrate and/or ice in the vicinity of the wellbore. The latter is caused by continuous cooling, and is the reason why large amounts of gas that may have been released in the reservoir in the course of earlier dissociation cannot be easily recovered.

Advanced Acid Gas Separation Technology for the Utilization of Low Rank Coals  

SciTech Connect

Air Products has developed a potentially ground-breaking technology – Sour Pressure Swing Adsorption (PSA) – to replace the solvent-based acid gas removal (AGR) systems currently employed to separate sulfur containing species, along with CO{sub 2} and other impurities, from gasifier syngas streams. The Sour PSA technology is based on adsorption processes that utilize pressure swing or temperature swing regeneration methods. Sour PSA technology has already been shown with higher rank coals to provide a significant reduction in the cost of CO{sub 2} capture for power generation, which should translate to a reduction in cost of electricity (COE), compared to baseline CO{sub 2} capture plant design. The objective of this project is to test the performance and capability of the adsorbents in handling tar and other impurities using a gaseous mixture generated from the gasification of lower rank, lignite coal. The results of this testing are used to generate a high-level pilot process design, and to prepare a techno-economic assessment evaluating the applicability of the technology to plants utilizing these coals.

Fiber Optic Sensing Technology for Detecting Gas Hydrate Formation and Decomposition  

SciTech Connect

A fiber optic-based distributed sensing system (DSS) has been integrated with a large volume (72 L) pressure vessel providing high spatial resolution, time resolved, 3-D measurement of hybrid temperature-strain (TS) values within experimental sediment gas hydrate systems. Areas of gas hydrate formation (exothermic) and decomposition (endothermic) can be characterized through this proxy by time series analysis of discrete data points collected along the length of optical fibers placed within a sediment system. Data is visualized as a 'movie' of TS values along the length of each fiber over time. Experiments conducted in the Seafloor Processing Simulator (SPS) at Oak Ridge National Laboratory show clear indications of hydrate formation and dissociation events at expected P-T conditions given the thermodynamics of the CH4-H2O system. The high spatial resolution achieved with fiber optic technology makes the DSS a useful tool for visualizing time resolved formation and dissociation of gas hydrates in large-scale sediment experiments.

High-temperature turbine technology program hot-gas path development test. Part II. Testing  

SciTech Connect

This topical report of the US Department of Energy High-Temperature Turbine Technology (DOE-HTTT) Phase II program presents the results of testing full-scale water-cooled first-stage and second-stage turbine nozzles at design temperature and pressure to verify that the designs are adequate for operation in a full-scale turbine environment. Low-cycle fatigue life of the nozzles was demonstrated by subjecting cascade assemblies to several hundred simulated startup/shutdown turbine cycles. This testing was accomplished in the Hot-Gas Path Development Test Stand (HGPDTS), which is capable of evaluating full-scale combustion and turbine nozzle components. A three-throat cascade of the first-stage turbine nozzle was successfully tested at a nozzle inlet gas temperature of 2630/sup 0/F and a nozzle inlet pressure of 11.3 atmospheres. In addition to steady-state operation at the design firing temperature, the nozzle cascade was exposed to a simulated startup/shutdown turbine cycle by varying the firing temperature. A total of 42 h at the design point and 617 thermal cycles were accumulated during the test periods. First-stage nozzle test results show that measured metal and coolant temperatures correspond well to the predicted design values. This nozzle design has been shown to be fully satisfactory for the application (2600/sup 0/F), with growth capability to 3000/sup 0/F firing temperature. A post-test metallurgical examination of sectioned portions of the tested nozzles shows a totally bonded structure, confirming the test results and attesting to the successful performance of water-cooled composite nozzle hardware.

LOW-ENGINE-FRICTION TECHNOLOGY FOR ADVANCED NATURAL-GAS RECIPROCATING ENGINES  

SciTech Connect

This program aims at improving the efficiency of advanced natural-gas reciprocating engines (ANGRE) by reducing piston/ring assembly friction without major adverse effects on engine performance, such as increased oil consumption and emissions. An iterative process of simulation, experimentation and analysis, are being followed towards achieving the goal of demonstrating a complete optimized low-friction engine system. To date, a detailed set of piston/ring dynamic and friction models have been developed and applied that illustrated the fundamental relationships between design parameters and friction losses. Various low-friction strategies and ring-design concepts have been explored, and engine experiments have been done on a full-scale Waukesha VGF F18 in-line 6 cylinder power generation engine rated at 370 kW at 1800 rpm. Current accomplishments include designing and testing ring-packs using a subtle top-compression-ring profile (skewed barrel design), lowering the tension of the oil-control ring, employing a negative twist to the scraper ring to control oil consumption. Initial test data indicate that piston ring-pack friction was reduced by 35% by lowering the oil-control ring tension alone, which corresponds to a 1.5% improvement in fuel efficiency. Although small in magnitude, this improvement represents a first step towards anticipated aggregate improvements from other strategies. Other ring-pack design strategies to lower friction have been identified, including reduced axial distance between the top two rings, tilted top-ring groove. Some of these configurations have been tested and some await further evaluation. Colorado State University performed the tests and Waukesha Engine Dresser, Inc. provided technical support. Key elements of the continuing work include optimizing the engine piston design, application of surface and material developments in conjunction with improved lubricant properties, system modeling and analysis, and continued technology demonstration in an actual full-sized reciprocating natural-gas engine.

Existing and anticipated technology strategies for reducing greenhouse gas emissions in Korea’s petrochemical and steel industries  

Science Journals Connector (OSTI)

This study examines the existing and anticipated technology strategies for reducing greenhouse gas (GHG) emissions in Korea’s petrochemical and steel industries. The results of the cluster analysis identify three types of technology strategies employed by firms for reducing GHG emissions: “wait-and-see” “in-process-focused”, and “all-round” strategies. The “in-process-focused” strategy was the most widely used strategy, followed by the “all-round” strategy. However, firms in these industries are expected to change their technology strategies to “treatment-reliance”, “inbound-substitution”, and “all-round” strategies in 5–10 years by employing a wider range of technology options to respond more effectively to the issue of GHG emissions. The demand for new energy sources and raw material substitutes is expected to strengthen in the near future as related technologies advance rapidly and become more widely available.

Advances of flue gas desulfurization technology for coal-fired boilers and strategies for sulfur dioxide pollution prevention in China  

SciTech Connect

Coal is one of the most important kinds of energy resources at the present time and in the immediate future in China. Sulfur dioxide resulting from combustion of coal is one of the principle pollutants in the air. Control of SO{sub 2} discharge is still a major challenge for environmental protection in developing China. In this paper, research, development and application of technology of flue gas desulfurization (FGD) for coal-fired boilers in China will be reviewed with emphasis on cost-effective technology, and the development trends of FGD technology, as well as the strategy for SO{sub 2} discharge control in China, will be analyzed. A practical technology for middle-small-sized boilers developed by the primary author and the field investigation results will also be presented. At present, there are four major kinds of FGD technologies that are practical to be applied in China for their cost-effectiveness and efficiency to middle-small-sized boilers. An important development trend of the FGD technology for middle-small-sized boilers for the next decade is improvement of the existing cost-effective wet-type FGD technology, and in the future it will be the development of dry-type FGD technology. For middle-sized generating boilers, the development direction of the FGD technology is the spraying and drying process. For large-sized generating boilers, the wet-type limestone-plaster process will still be applied in the immediate future, and dry-type FGD technologies, such as ammonia with electron beam irradiation, will be developed in the future. State strategies for the control of SO{sub 2} discharge will involve the development and popularization of efficient coal-fired devices, extension of gas coal and liquefied coal, spreading coal washing, and centralized heating systems.

Independent Validation and Verification of Process Design and Optimization Technology Diagnostic and Control of Natural Gas Fired Furnaces via Flame Image Analysis Technology  

SciTech Connect

The United States Department of Energy, Industrial Technologies Program has invested in emerging Process Design and Optimizations Technologies (PDOT) to encourage the development of new initiatives that might result in energy savings in industrial processes. Gas fired furnaces present a harsh environment, often making accurate determination of correct air/fuel ratios a challenge. Operation with the correct air/fuel ratio and especially with balanced burners in multi-burner combustion equipment can result in improved system efficiency, yielding lower operating costs and reduced emissions. Flame Image Analysis offers a way to improve individual burner performance by identifying and correcting fuel-rich burners. The anticipated benefit of this technology is improved furnace thermal efficiency, and lower NOx emissions. Independent validation and verification (V&V) testing of the FIA technology was performed at Missouri Forge, Inc., in Doniphan, Missouri by Environ International Corporation (V&V contractor) and Enterprise Energy and Research (EE&R), the developer of the technology. The test site was selected by the technology developer and accepted by Environ after a meeting held at Missouri Forge. As stated in the solicitation for the V&V contractor, 'The objective of this activity is to provide independent verification and validation of the performance of this new technology when demonstrated in industrial applications. A primary goal for the V&V process will be to independently evaluate if this technology, when demonstrated in an industrial application, can be utilized to save a significant amount of the operating energy cost. The Seller will also independently evaluate the other benefits of the demonstrated technology that were previously identified by the developer, including those related to product quality, productivity, environmental impact, etc'. A test plan was provided by the technology developer and is included as an appendix to the summary report submitted by Environ (Appendix A). That plan required the V&V contractor to: (1) Establish the as-found furnace operating conditions; (2) Tune the furnace using currently available technology to establish baseline conditions; (3) Tune the furnace using the FIA technology; and (4) Document the improved performance that resulted from application of the FIA technology. It is important to note that the testing was not designed to be a competition or comparison between two different methodologies that could be used for furnace tuning. Rather, the intent was to quantify improvements in furnace performance that could not be achieved with existing technology. Therefore, the measure of success is improvement beyond the furnace efficiency obtainable using existing furnace optimization methods rather than improvement from the as found condition.

Bench-scale demonstration of hot-gas desulfurization technology. Quarterly report, October 1 - December 31, 1994  

SciTech Connect

The U.S. Department of Energy (DOE), Morgantown Energy Technology Center (METC), is sponsoring research in advanced methods for controlling contaminants in hot coal gasifier gas (coal gas) streams of integrated gasification combined-cycle (IGCC) power systems. The programs focus on hot-gas particulate removal and desulfurization technologies that match or nearly match the temperatures and pressures of the gasifier, cleanup system, and power generator. The work seeks to eliminate the need for expensive heat recovery equipment, reduce efficiency losses due to quenching, and minimize wastewater treatment costs. Hot-gas desulfurization research has focused on regenerable mixed-metal oxide sorbents which can reduce the sulfur in coal gas to less than 20 ppmv and can be regenerated in a cyclic manner with air for multicycle operation. Zinc titanate (Zn{sub 2}TiO{sub 4} or ZnTiO{sub 3}), formed by a solid-state reaction of zinc (ZnO) and titanium dioxide (TiO{sub 2}), is currently one of the leading sorbents. This report summarizes the highlights and accomplishments of the October slipstream test run of the Zinc Titanate Fluid Bed Desulfurization/Direct Sulfur Recovery Process (ZTFBD/DSRP) Mobile Laboratory at the Department of Energy`s Morgantown Energy Technology Center. Although the run had to be shortened due to mechanical problems with METC`s gasifier, there was sufficient on-stream time to demonstrate highly successful operation of both the zinc titanate fluid bed desulfurization and the DSRP with actual coal gas.

Energy and greenhouse gas emission effects of corn and cellulosic ethanol with technology improvements and land use changes.  

SciTech Connect

Use of ethanol as a transportation fuel in the United States has grown from 76 dam{sup 3} in 1980 to over 40.1 hm{sup 3} in 2009 - and virtually all of it has been produced from corn. It has been debated whether using corn ethanol results in any energy and greenhouse gas benefits. This issue has been especially critical in the past several years, when indirect effects, such as indirect land use changes, associated with U.S. corn ethanol production are considered in evaluation. In the past three years, modeling of direct and indirect land use changes related to the production of corn ethanol has advanced significantly. Meanwhile, technology improvements in key stages of the ethanol life cycle (such as corn farming and ethanol production) have been made. With updated simulation results of direct and indirect land use changes and observed technology improvements in the past several years, we conducted a life-cycle analysis of ethanol and show that at present and in the near future, using corn ethanol reduces greenhouse gas emission by more than 20%, relative to those of petroleum gasoline. On the other hand, second-generation ethanol could achieve much higher reductions in greenhouse gas emissions. In a broader sense, sound evaluation of U.S. biofuel policies should account for both unanticipated consequences and technology potentials. We maintain that the usefulness of such evaluations is to provide insight into how to prevent unanticipated consequences and how to promote efficient technologies with policy intervention.

LOW-ENGINE-FRICTION TECHNOLOGY FOR ADVANCED NATURAL-GAS RECIPROCATING ENGINES  

SciTech Connect

This program aims at improving the efficiency of advanced natural-gas reciprocating engines (ANGRE) by reducing piston and piston ring assembly friction without major adverse effects on engine performance, such as increased oil consumption and wear. An iterative process of simulation, experimentation and analysis is being followed towards achieving the goal of demonstrating a complete optimized low-friction engine system. To date, a detailed set of piston and piston-ring dynamic and friction models have been developed and applied that illustrate the fundamental relationships between design parameters and friction losses. Low friction ring designs have already been recommended in a previous phase, with full-scale engine validation partially completed. Current accomplishments include the addition of several additional power cylinder design areas to the overall system analysis. These include analyses of lubricant and cylinder surface finish and a parametric study of piston design. The Waukesha engine was found to be already well optimized in the areas of lubricant, surface skewness and honing cross-hatch angle, where friction reductions of 12% for lubricant, and 5% for surface characteristics, are projected. For the piston, a friction reduction of up to 50% may be possible by controlling waviness alone, while additional friction reductions are expected when other parameters are optimized. A total power cylinder friction reduction of 30-50% is expected, translating to an engine efficiency increase of two percentage points from its current baseline towards the goal of 50% efficiency. Key elements of the continuing work include further analysis and optimization of the engine piston design, in-engine testing of recommended lubricant and surface designs, design iteration and optimization of previously recommended technologies, and full-engine testing of a complete, optimized, low-friction power cylinder system.

Development of Brazing Technology for Use in High- Temperature Gas Separation Equipment  

SciTech Connect

The development of high-temperature electrochemical devices such as oxygen and hydrogen separators, fuel gas reformers, solid oxide fuel cells, and chemical sensors is part of a rapidly expanding segment of the solid state technology market. These devices employ an ionic conducting ceramic as the active membrane that establishes the electrochemical potential of the device, either under voltage (i.e. to carry out gas separation) or under chemical gradient (to develop an electrical potential and thereby generate electrical power). Because the device operates under an ionic gradient that develops across the electrolyte, hermiticity across this layer is paramount. That is, not only must this thin ceramic membrane be dense with no interconnected porosity, but it must be connected to the rest of the device, typically constructed from a heat resistant alloy, with a high-temperature, gas-tight seal. A significant engineering challenge in fabricating these devices is how to effectively join the thin electrochemically active membrane to the metallic body of the device such that the resulting seal is hermetic, rugged, and stable during continuous high temperature operation. Active metal brazing is the typical method of joining ceramic and metal engineering components. It employs a braze alloy that contains one or more reactive elements, often titanium, which will chemically reduce the ceramic faying surface and greatly improve its wetting behavior and adherence with the braze. However, recent studies of these brazes for potential use in fabricating high-temperature electrochemical devices revealed problems with interfacial oxidation and subsequent joint failure [1,2]. Specifically, it was found that the introduction of the ceramic electrolyte and/or heat resistant metal substrate dramatically affects the inherent oxidation behavior of the braze, often in a deleterious manner. These conclusions pointed to the need for an oxidation resistant, high-temperature ceramic-to-metal braze and consequently lead to the development of the novel reactive air brazing (RAB) concept. The goal in RAB is to reactively modify one or both oxide faying surfaces with an oxide compound dissolved in a molten noble metal alloy such that the newly formed surface is readily wetted by the remaining liquid filler material. In many respects, this concept is similar to active metal brazing, except that joining can be conducted in air and the final joint will be resistant to oxidation at high temperature. Potentially, there are a number of metal oxide-noble metal systems that can be considered for RAB, including Ag-CuO, Ag-V2O5, and Pt-Nb2O5. Our current interest is in determining whether the Ag-CuO system is suitable for air brazing functional ceramic-to-metal joints such as those needed in practical electrochemical devices. In a series of studies, the wetting behavior of the Ag-CuO braze was investigated with respect to a number of potential hydrogen separation, oxygen separation, and fuel cell electrolyte membrane materials and heat resistant metal systems, including: alumina, (La0.6Sr0.4)(Co0.2Fe0.8)O3, (La0.8Sr0.2)FeO3, YSZ, fecralloy, and Crofer-22APU. Selected findings from these studies as well as from our work on joint strength and durability during high-temperature exposure testing will be discussed.

Advanced industrial gas turbine technology readiness demonstration. Quarterly technical progress report No. 12, 1 December 1979-29 February 1980  

SciTech Connect

The component technology base required for improved industrial gas turbine conversion efficiency is discussed. Specific goals are to demonstrate the high-pressure compressor and turbine cooling technologies required to achieve industrial gas turbine efficiencies of 34 to 36% simple cycle and 45 to 48% in combined cycle operation while reducing the number of compressor and turbine parts 80% over state-of-the-art units. The approach involves combining some of the most advanced aircraft turbine cooling and high-pressure compressor technology with the simplicity and ruggedness required of industrial engines to achieve not only improved performance, but also increased durability and low initial cost. The program currently consists of two phases. Phase I, which has been completed, included the conceptual definition of an industrial gas turbine capable of meeting the above goals and the aerothermodynamic designs of compressor and turbine component test rigs. Phase II, which is in progress, consists of component validation testing of the high-pressure compressor and turbine cooling designs which evolved in Phase I. During this quarter, work continued on Phase II, Task III - Compressor Rig Assembly and Test. Assembly of the compressor rig has been completed and final preparation of the rig for transporting to the test facility is in progress.

A new technology for producing hydrogen and adjustable ratio syngas from coke oven gas  

SciTech Connect

About 15 billion Nm{sup 3} coke oven gas (COG) is emitted into the air in Shanxi Province in China as air pollutants. It is also a waste of precious chemical resources. In this study, COG was purified respectively by four methods including refrigeration, fiberglass, silica gel, and molecular sieve. Purified COG was separated by a prism membrane into two gas products. One consists mainly of H{sub 2} ({gt}90 vol %) and the other is rich in CH{sub 4} ({gt}60 vol %) with their exact compositions to vary with the membrane separation pressure and outlet gas flow ratio. The gas rich in CH{sub 4} was partially oxidized with oxygen in a high-temperature fixed-bed quartz reactor charged with coke particles of 10 mm size. At 1200-1300{sup o}C, a CH{sub 4} conversion of {gt}99% could be obtained. The H{sub 2}/CO ratio in the synthesis product gas can be adjusted in the range 0.3-1.4, very favorable for further C1 synthesis. 10 refs., 17 figs., 1t ab.

Low Temperature X-ray Diffraction Study of Natural Gas Hydrate Samples from the Gulf of Mexico Low Temperature X-ray Diffraction Study of Natural Gas Hydrate Samples from the Gulf of Mexico Low Temperature X-ray Diffraction Study of Natural Gas Hydrate Samples from the Gulf of Mexico Authors: C.J. Rawn, R. Sassen, S.M. Ulrich, E.A. Payzant, B.C. Chakoumakos, and T.J. Phelps Venue: 6th International Conference on Gas Hydrates, Fairmont Hotel, Vancouver, Canada July 6-10, 2008. http://www.icgh.org/ [external site]. Abstract: Clathrate hydrates of methane and other small alkanes occur widespread as terrestrial components in marine sediments of the continental margins and in permafrost sediments of the arctic. Quantitative study of natural clathrate hydrates is hampered by the difficulty in obtaining pristine samples, particularly from submarine environments. Bringing samples of clathrate hydrate from the seafloor at depths without compromising their integrity is not trivial. Most physical property measurements are based on studies of laboratory-synthesized samples. Here we report x-ray powder diffraction measurements of a natural gas hydrate sample from the Green Canyon, Gulf of Mexico (GOM). The first data were collected in 2002 and revealed ice and structure II gas hydrate. In the subsequent time the sample has been stored in liquid nitrogen. Recently new x-ray powder diffraction data have been collected as a function of temperature. Rietveld refinements on this new data show that there is approximately 50 wt % gas hydrate with structure type II and 50% ice at -140, -130, -115, -100, and -85oC. The Rietveld refinements on the data sets collected at -70 and -55oC show the amount of structure type II hydrate decreasing to approximately 40% and 37%, respectively. The Rietveld refinement of the data set collected at -40oC shows a sharp decrease in the amount of structure type II hydrate to approximately 9%. Rietveld refinements on the data sets collected at -25 and -10oC indicated that the structure type II hydrate is still present at 7 and 3%, respectively

Saturable absorption and 'slow light'  

E-Print Network (OSTI)

Quantitative evaluation of some recent 'slow light' experiments based on coherent population oscillations (CPO) shows that they can be more simply interpreted as saturable absorption phenomena. Therefore they do not provide an unambiguous demonstration of 'slow light'. Indeed a limiting condition on the spectral bandwidth is not generally satisfied, such that the requirements for burning a narrow spectral hole in the homogeneously broadened absorption line are not met. Some definitive tests of 'slow light' phenomena are suggested, derived from analysis of phase shift and pulse delay for a saturable absorber

Development of monitoring and control technology based on trace gas monitoring. Final report  

SciTech Connect

Trace gases are generated by many biological reactions. During anaerobic decomposition, trace levels of hydrogen (H{sub 2}) and carbon monoxide (CO) gases are produced. It was shown previously that these trace gases are intrinsically related to the biochemical reactions occurring and, therefore, offer promise for on-line process monitoring and control. This work was designed to test how effectively hydrogen and CO could be to monitor high-rate anaerobic systems that has significant mass transfer and complex hydraulics. An experimental program was designed to examine the behavior of an upflow anaerobic sludge blanket (UASB) reactor system under steady state and in response to organic loading perturbations. The responses of trace gases CO and H{sub 2} were tracked using an on-line, real-time gas-monitoring system linked to a computer-controlled data acquisition package. Data on conventional process parameters such as pH, chemical oxygen demand (COD), volatile fatty acids (VFAs) were concurrently collected. Monitoring of conventional process indicators (i.e., pH, VFA, gas production) and trace gas (H{sub 2} and CO) indicators was conducted using a matrix of nine different steady-state OLRs (4-23 kg COD/m{sup 3} -d) and system HRTs (0.5 to 2.5 days) was performed to determine any correlation among the indicators. Of OLR, HRT, and influent COD, only OLR had any significant influence on the process indicators examined. All parameters except methane increased with increases in OLR; methane decreased with increased OLR. The OLR and gas production rate (GP) were observed to be linearly correlated.

Advanced separation technology for flue gas cleanup. Quarterly technical report No. 8, [January--March 1994  

SciTech Connect

During the first quarter of 1994, we continued work on Tasks 2, 3, 4, 5, and 6. We also began work on Task 7. In Task 2, we incorporated 4.5% O{sub 2} into our simulated flue gas stream during this quarter`s NO{sub x}-absorption experiments. We also ran experiments using Cobalt (II)-phthalocyanine as an absorbing agent We observed higher absorption capacities when using this solution with the simulated flue gas containing O{sub 2}. In Task 3, we synthesized a few EDTA polymer analogs. We also began scaled up synthesis of Co(II)-phthalocyanine for use in Task 5. In Task 4, we performed experiments for measuring distribution coefficients (m{sub i}) Of SO{sub 2} between aqueous and organic phases. This was done using the liquor regenerating apparatus described in Task 6. In Task 5, we began working with Co(II)-phthalocyanine in the 301 fiber hollow fiber contactor. We also calculated mass transfer coefficients (K{sub olm}) for these runs, and we observed that the gas side resistance dominates mass transfer. In Task 6, in the liquor regeneration apparatus, we observed 90% recovery of SO{sub 2} by DMA from water used as the scrubbing solution. We also calculated the distribution of coefficients (m{sub i}). In Task 7, we established and began implementing a methodology for completing this task.

Slow modes in Keplerian disks  

E-Print Network (OSTI)

Low-mass disks orbiting a massive body can support "slow" normal modes, in which the eigenfrequency is much less than the orbital frequency. Slow modes are lopsided, i.e., the azimuthal wavenumber m=1. We investigate the properties of slow modes, using softened self-gravity as a simple model for collective effects in the disk. We employ both the WKB approximation and numerical solutions of the linear eigenvalue equation. We find that all slow modes are stable. Discrete slow modes can be divided into two types, which we label g-modes and p-modes. The g-modes involve long leading and long trailing waves, have properties determined by the self-gravity of the disk, and are only present in narrow rings or in disks where the precession rate is dominated by an external potential. In contrast, the properties of p-modes are determined by the interplay of self-gravity and other collective effects. P-modes involve both long and short waves, and in the WKB approximation appear in degenerate leading/trailing pairs. Disks support a finite number---sometimes zero---of discrete slow modes, and a continuum of singular modes.

Low cost hydrogen/novel membrane technology for hydrogen separation from synthesis gas  

SciTech Connect

To make the coal-to-hydrogen route economically attractive, improvements are being sought in each step of the process: coal gasification, water-carbon monoxide shift reaction, and hydrogen separation. This report addresses the use of membranes in the hydrogen separation step. The separation of hydrogen from synthesis gas is a major cost element in the manufacture of hydrogen from coal. Separation by membranes is an attractive, new, and still largely unexplored approach to the problem. Membrane processes are inherently simple and efficient and often have lower capital and operating costs than conventional processes. In this report current ad future trends in hydrogen production and use are first summarized. Methods of producing hydrogen from coal are then discussed, with particular emphasis on the Texaco entrained flow gasifier and on current methods of separating hydrogen from this gas stream. The potential for membrane separations in the process is then examined. In particular, the use of membranes for H{sub 2}/CO{sub 2}, H{sub 2}/CO, and H{sub 2}/N{sub 2} separations is discussed. 43 refs., 14 figs., 6 tabs.

Dual-fuel natural gas/diesel engines: Technology, performance, and emissions. Topical report, February 1993-November 1994  

SciTech Connect

An investigation of current dual-fuel natural gas/diesel engine design, performance, and emissions was conducted. The most pressing technological problems associated with dual-fuel engine use were identified along with potential solutions. It was concluded that dual-fuel engines can achieve low NOx and particulate emissions while retaining fuel-efficiency and BMEP levels comparable to those of diesel engines. The investigation also examined the potential economic impact of dual-fuel engines in diesel-electric locomotives, marine vessels, farm equipment, construction, mining, and industrial equipment, and stand-alone electricity generation systems. Recommendations for further additional funding to support research, development, and demonstration in these applications were then presented.

LOW-ENGINE-FRICTION TECHNOLOGY FOR ADVANCED NATURAL-GAS RECIPROCATING ENGINES  

SciTech Connect

This program aims at improving the efficiency of advanced natural-gas reciprocating engines (ANGRE) by reducing piston/ring assembly friction without major adverse effects on engine performance, such as increased oil consumption and emissions. A detailed set of piston/ring dynamic and friction models have been developed and applied that illustrated the fundamental relationships between design parameters and friction losses. Various low-friction strategies and concepts have been explored, and engine experiments will validate these concepts. An iterative process of experimentation, simulation and analysis, will be followed with the goal of demonstrating a complete optimized low-friction engine system. As planned, MIT has developed guidelines for an initial set of low-friction piston-ring-pack designs. Current recommendations focus on subtle top-piston-ring and oil-control-ring characteristics. A full-scale Waukesha F18 engine has been installed at Colorado State University and testing of the baseline configuration is in progress. Components for the first design iteration are being procured. Subsequent work includes examining the friction and engine performance data and extending the analyses to other areas to evaluate opportunities for further friction improvement and the impact on oil consumption/emission and wear, towards demonstrating an optimized reduced-friction engine system.

Devonian Woodford Formation of the Permian Basin Devonian Woodford Formation of the Permian Basin The Devonian Woodford Formation of the Permian Basin: Complex Depositional and Temporal Variations Across an Anaerobic Marine Basin Authors: S. C. Ruppel and R. G. Loucks Venue: 2008 American Association of Petroleum Geologists (AAPG) Annual Convention and Exhibition, San Antonio, TX, April 19-24, 2008 “The Geology of Mudrocks”, session chaired by S. C. Ruppel and R. G. Loucks (http://www.aapg.org) Abstract: The Woodford Formation, a key oil and gas source rock in the Permian Basin of Texas and New Mexico, is part of an extensive, platform marginal, organic-rich, mudrock succession that formed along the southern and western margins of Laurussia during the Devonian and Mississippian. Studies of >35 Woodford cores reveal wide variability in facies, organic content, and mineralogy that can be related to age and paleogeographic setting. Woodford facies include silt-rich mudstones (detrital silica), siliceous mudstones (biogenic silica), calcareous mudstones, and claystones. Recent studies show that facies are partitioned between two temporally distinct successions: a Middle Devonian silt- and carbonate-rich section that is irregularly distributed across the basin, and an Upper Devonian siliceous claystone/mudstone section that is widespread and separated from underlying successions by a significant hiatus. All Woodford rocks contain mixtures of illite, kaolinite, chlorite, and mixed layer clays; total clay and chlorite abundance is lowest in distal Upper Devonian rocks. Although silica content is variable, Upper Devonian mudrocks typically contain more abundant biogenic silica, especially in distal parts of the basin, whereas Middle Devonian rocks are dominated by detrital silica. The two successions display consistent differences in depositional facies. The silt-rich Middle Devonian section is cross-laminated, locally graded, and commonly bioturbated. Upper Devonian mudrocks, by contrast, are dominated by fine-scale, parallel laminations and show no evidence of infaunal activity. These rocks also contain common conodonts, radiolarians, spore bodies, and deep-water brachiopods. The data suggest that the lower Woodford was deposited by deep water, turbid flow, whereas the upper Woodford accumulated under more distal, low energy, poorly oxygenated, hemipelagic conditions

Targeted technology applications for infield reserve growth: A synopsis of the Secondary Natural Gas Recovery project, Gulf Coast Basin. Topical report, September 1988--April 1993  

SciTech Connect

The Secondary Natural Gas Recovery (SGR): Targeted Technology Applications for Infield Reserve Growth is a joint venture research project sponsored by the Gas Research Institute (GRI), the US Department of Energy (DOE), the State of Texas through the Bureau of Economic Geology at The University of Texas at Austin, with the cofunding and cooperation of the natural gas industry. The SGR project is a field-based program using an integrated multidisciplinary approach that integrates geology, geophysics, engineering, and petrophysics. A major objective of this research project is to develop, test, and verify those technologies and methodologies that have near- to mid-term potential for maximizing recovery of gas from conventional reservoirs in known fields. Natural gas reservoirs in the Gulf Coast Basin are targeted as data-rich, field-based models for evaluating infield development. The SGR research program focuses on sandstone-dominated reservoirs in fluvial-deltaic plays within the onshore Gulf Coast Basin of Texas. The primary project research objectives are: To establish how depositional and diagenetic heterogeneities cause, even in reservoirs of conventional permeability, reservoir compartmentalization and hence incomplete recovery of natural gas. To document examples of reserve growth occurrence and potential from fluvial and deltaic sandstones of the Texas Gulf Coast Basin as a natural laboratory for developing concepts and testing applications. To demonstrate how the integration of geology, reservoir engineering, geophysics, and well log analysis/petrophysics leads to strategic recompletion and well placement opportunities for reserve growth in mature fields.

Comprehensive report to Congress: Clean Coal Technology program: Evaluation of gas reburning and low-NO sub x burners on a wall-fired boiler  

SciTech Connect

This report briefly describes the Gas Reburning and Low-NO{sub x} Burners technology which is a low-cost technology that can be applied in both retrofit and new applications. This demonstration will be conducted on a utility boiler in Colorado at Cherokee Station {number sign}3; however, the technology is applicable to industrial boilers and other combustion systems. Although this technology is primarily a NO{sub x} reduction technology, some reductions in other emissions will take place. Since 15--20% of the coal is replaced with natural gas, SO{sub 2} and particulate emissions are reduced commensurately. Also the lower carbon-to-hydrogen ratio of natural gas compared to coal reduces CO{sub 2} emissions. The formation of NO{sub x} is controlled by several factors: (1) the amount of nitrogen that is chemically bound in the fuel; (2) the flame temperature; (3) the residence time that combustion products remain at very high temperatures; and (4) the amount of excess oxygen available, especially at the hottest parts of the flame. Decreasing any of these parameters, tends to reduce NO{sub x} formation. 6 figs., 1 tab.

Lead Slowing Down Spectrometer Research Plans  

SciTech Connect

The MPACT-funded Lead Slowing Down Spectrometry (LSDS) project has been evaluating the feasibility of using LSDS techniques to assay fissile isotopes in used nuclear fuel assemblies. The approach has the potential to provide considerable improvement in the assay of fissile isotopic masses in fuel assemblies compared to other non-destructive techniques in a direct and independent manner. The LSDS collaborations suggests that the next step to in empirically testing the feasibility is to conduct measurements on fresh fuel assemblies to understand investigate self-attenuation and fresh mixed-oxide (MOX) fuel rodlets so we may betterto understand extraction of masses for 235U and 239Pu. While progressing toward these goals, the collaboration also strongly suggests the continued development of enabling technology such as detector development and algorithm development, thatwhich could provide significant performance benefits.

Current status of MHI CO2 capture plant technology, large scale demonstration project and road map to commercialization for coal fired flue gas application  

Science Journals Connector (OSTI)

(1) It is becoming increasingly evident that the prolonged utilization of fossil fuels for primary energy production, especially coal which is relatively cheap and abundant, is inevitable and that Carbon Capture and Storage (CCS) technology can significantly reduce CO2 emissions from this sector thus allowing the continued environmentally sustainable use of this important energy commodity on a global basis. (2) MHI has co-developed the Kansai Mitsubishi Carbon Dioxide Recovery Process (KM-CDR Process™) and KS-1™ absorbent, which has been deployed in seven CO2 capture plants, now under commercial operation operating at a CO2 capture capacity of 450 metric tons per day (tpd). In addition, a further two commercial plants are now under construction all of which capture CO2 from natural gas fired flue gas boilers and steam reformers. Accordingly this technology is now available for commercial scale CO2 capture for gas boiler and gas turbine application. (3) However before offering commercial CO2 capture plants for coal fired flue gas application, it is necessary to verify the influence of, and develop countermeasures for, related impurities contained in coal fired flue gas. This includes the influence on both the absorbent and the entire system of the CO2 capture plant to achieve high operational reliability and minimize maintenance requirements. (4) Preventing the accumulation of impurities, especially the build up of dust, is very important when treating coal fired flue gas and MHI has undertaken significant work to understand the impact of impurities in order to achieve reliable and stable operating conditions and to efficiently optimize integration between the CO2 capture plant, the coal fired power plant and the flue gas clean up equipment. (5) To achieve this purpose, MHI constructed a 10 tpd CO2 capture demonstration plant at the Matsushima 1000 MW Power Station and confirmed successful, long term demonstration following ?5000 hours of operation in 2006–07 with 50% financial support by RITE, as a joint program to promote technological development with the private sector, and cooperation from J-POWER. (6) Following successful demonstration testing at Matsushima, additional testing was undertaken in 2008 to examine the impact of entrainment of higher levels of flue gas impurities (primarily \\{SOx\\} and dust by bypassing the existing FGD) and to determine which components of the CO2 recovery process are responsible for the removal of these impurities. Following an additional 1000 demonstration hours, results indicated stable operational performance in relation to the following impurities; (1) SO2: Even at higher SO2 concentrations were almost completely removed from the flue gas before entering the CO2 absorber. (2) Dust: The accumulation of dust in the absorbent was higher, leading to an advanced understanding of the behavior of dust in the CO2 capture plant and the dust removal efficiency of each component within the CO2 recovery system. The data obtained is useful for the design of large-scale units and confirms the operating robustness of the CO2 capture plant accounting for wide fluctuations in impurity concentrations. (7) This important coal fired flue gas testing showed categorically that minimizing the accumulation of large concentrations of impurities, and to suppress dust concentrations below a prescribed level, is important to achieve long-term stable operation and to minimize maintenance work for the CO2 capture plant. To comply with the above requirement, various countermeasures have been developed which include the optimization of the impurity removal technology, flue gas pre treatment and improved optimization with the flue gas desulfurization facility. (8) In case of a commercial scale CO2 capture plant applied for coal fired flue gas, its respective size will be several thousand tpd which represents a considerable scale-up from the 10 tpd demonstration plant. In order to ensure the operational reliability and to accurately confirm the influence and the behavior of the impurities in coal fired fl

Model system for slow dynamics  

Science Journals Connector (OSTI)

Systems whose dynamics are described by a quasilogarithmic or stretched-exponential time dependence are usually fitted by models which use disorder to create a distribution of relaxation times. Here we describe a model which decays slowly towards equilibrium but does not require disorder to provide the slow dynamics. The model consists of a spin system with the spins interacting via the dipole-dipole interaction. The model is able to replicate the more pronounced features observed in the magnetization decay of magnetic systems and high-temperature superconductors.

ADVANCED RECIPROCATING COMPRESSION TECHNOLOGY (ARCT)  

SciTech Connect

The U.S. natural gas pipeline industry is facing the twin challenges of increased flexibility and capacity expansion. To meet these challenges, the industry requires improved choices in gas compression to address new construction and enhancement of the currently installed infrastructure. The current fleet of installed reciprocating compression is primarily slow-speed integral machines. Most new reciprocating compression is and will be large, high-speed separable units. The major challenges with the fleet of slow-speed integral machines are: limited flexibility and a large range in performance. In an attempt to increase flexibility, many operators are choosing to single-act cylinders, which are causing reduced reliability and integrity. While the best performing units in the fleet exhibit thermal efficiencies between 90% and 92%, the low performers are running down to 50% with the mean at about 80%. The major cause for this large disparity is due to installation losses in the pulsation control system. In the better performers, the losses are about evenly split between installation losses and valve losses. The major challenges for high-speed machines are: cylinder nozzle pulsations, mechanical vibrations due to cylinder stretch, short valve life, and low thermal performance. To shift nozzle pulsation to higher orders, nozzles are shortened, and to dampen the amplitudes, orifices are added. The shortened nozzles result in mechanical coupling with the cylinder, thereby, causing increased vibration due to the cylinder stretch mode. Valve life is even shorter than for slow speeds and can be on the order of a few months. The thermal efficiency is 10% to 15% lower than slow-speed equipment with the best performance in the 75% to 80% range. The goal of this advanced reciprocating compression program is to develop the technology for both high speed and low speed compression that will expand unit flexibility, increase thermal efficiency, and increase reliability and integrity. Retrofit technologies that address the challenges of slow-speed integral compression are: (1) optimum turndown using a combination of speed and clearance with single-acting operation as a last resort; (2) if single-acting is required, implement infinite length nozzles to address nozzle pulsation and tunable side branch absorbers for 1x lateral pulsations; and (3) advanced valves, either the semi-active plate valve or the passive rotary valve, to extend valve life to three years with half the pressure drop. This next generation of slow-speed compression should attain 95% efficiency, a three-year valve life, and expanded turndown. New equipment technologies that address the challenges of large-horsepower, high-speed compression are: (1) optimum turndown with unit speed; (2) tapered nozzles to effectively reduce nozzle pulsation with half the pressure drop and minimization of mechanical cylinder stretch induced vibrations; (3) tunable side branch absorber or higher-order filter bottle to address lateral piping pulsations over the entire extended speed range with minimal pressure drop; and (4) semi-active plate valves or passive rotary valves to extend valve life with half the pressure drop. This next generation of large-horsepower, high-speed compression should attain 90% efficiency, a two-year valve life, 50% turndown, and less than 0.75 IPS vibration. This program has generated proof-of-concept technologies with the potential to meet these ambitious goals. Full development of these identified technologies is underway. The GMRC has committed to pursue the most promising enabling technologies for their industry.

ASSESSING AND FORECASTING, BY PLAY, NATURAL GAS ULTIMATE RECOVERY GROWTH AND QUANTIFYING THE ROLE OF TECHNOLOGY ADVANCEMENTS IN THE TEXAS GULF COAST BASIN AND EAST TEXAS  

SciTech Connect

A detailed natural gas ultimate recovery growth (URG) analysis of the Texas Gulf Coast Basin and East Texas has been undertaken. The key to such analysis was determined to be the disaggregation of the resource base to the play level. A play is defined as a conceptual geologic unit having one or more reservoirs that can be genetically related on the basis of depositional origin of the reservoir, structural or trap style, source rocks and hydrocarbon generation, migration mechanism, seals for entrapment, and type of hydrocarbon produced. Plays are the geologically homogeneous subdivision of the universe of petroleum pools within a basin. Therefore, individual plays have unique geological features that can be used as a conceptual model that incorporates geologic processes and depositional environments to explain the distribution of petroleum. Play disaggregation revealed important URG trends for the major natural gas fields in the Texas Gulf Coast Basin and East Texas. Although significant growth and future potential were observed for the major fields, important URG trends were masked by total, aggregated analysis based on a broad geological province. When disaggregated by plays, significant growth and future potential were displayed for plays that were associated with relatively recently discovered fields, deeper reservoir depths, high structural complexities due to fault compartmentalization, reservoirs designated as tight gas/low-permeability, and high initial reservoir pressures. Continued technology applications and advancements are crucial in achieving URG potential in these plays.

The effect of natural gas supply on US renewable energy and CO2 emissions  

Science Journals Connector (OSTI)

Increased use of natural gas has been promoted as a means of decarbonizing the US power sector, because of superior generator efficiency and lower CO2 emissions per unit of electricity than coal. We model the effect of different gas supplies on the US power sector and greenhouse gas (GHG) emissions. Across a range of climate policies, we find that abundant natural gas decreases use of both coal and renewable energy technologies in the future. Without a climate policy, overall electricity use also increases as the gas supply increases. With reduced deployment of lower-carbon renewable energies and increased electricity consumption, the effect of higher gas supplies on GHG emissions is small: cumulative emissions 2013–55 in our high gas supply scenario are 2% less than in our low gas supply scenario, when there are no new climate policies and a methane leakage rate of 1.5% is assumed. Assuming leakage rates of 0 or 3% does not substantially alter this finding. In our results, only climate policies bring about a significant reduction in future CO2 emissions within the US electricity sector. Our results suggest that without strong limits on GHG emissions or policies that explicitly encourage renewable electricity, abundant natural gas may actually slow the process of decarbonization, primarily by delaying deployment of renewable energy technologies.

Low cost hydrogen/novel membrane technology for hydrogen separation from synthesis gas. Task 1, Literature survey  

SciTech Connect

To make the coal-to-hydrogen route economically attractive, improvements are being sought in each step of the process: coal gasification, water-carbon monoxide shift reaction, and hydrogen separation. This report addresses the use of membranes in the hydrogen separation step. The separation of hydrogen from synthesis gas is a major cost element in the manufacture of hydrogen from coal. Separation by membranes is an attractive, new, and still largely unexplored approach to the problem. Membrane processes are inherently simple and efficient and often have lower capital and operating costs than conventional processes. In this report current ad future trends in hydrogen production and use are first summarized. Methods of producing hydrogen from coal are then discussed, with particular emphasis on the Texaco entrained flow gasifier and on current methods of separating hydrogen from this gas stream. The potential for membrane separations in the process is then examined. In particular, the use of membranes for H{sub 2}/CO{sub 2}, H{sub 2}/CO, and H{sub 2}/N{sub 2} separations is discussed. 43 refs., 14 figs., 6 tabs.

Obtaining slow beam spills at the SSC collider  

SciTech Connect

There is substantial interest in providing slow-spill external proton beams in parallel with ``interaction running`` at the 20 TeV SSC collider. The proposal is to cause a flux of particles to impinge on a target consisting of a bent crystal extraction channel. Additionally, a slow spill onto a conventional internal target could be used as a source of secondary beams for physics or test purposes and might also be used for B-physics as proposed for HERA. The ``natural`` beam loss rates from elastic and diffractive beam gas scattering and IP collisions are not sufficient to provide suitably intense external proton beams. To prevent loss of luminosity, the rf excitation is non-linear and preferentially blows up the halo of the beam. The ``target`` is to be located at a region of high dispersion forcing particles at the edge of the momentum space onto the target. T. Lohse in this workshop has described a proposed internal target to be used at HERA that will not employ rf excitation but will use the finite loss rates observed at the HERA machine. The Hera losses are caused by a variety of sources in addition to beam gas scattering or IP interactions. Initially, the beam lifetime at HERA was too short to obtain satisfactory integrated luminosities. Subsequently, through careful attention to detail, the beam lifetime was increased to > 20 hours. Even with these changes, present loss rates provide the required intensity onto an internal target. The Tevatron and SPS proton anti-proton colliders have had similar experiences with their investigations of loss rates and also find that beam lifetimes may be substantially shorter than expected solely from beam gas and IP interactions. This paper proposes deliberately introducing controlled errors li

Vacuum Technology  

SciTech Connect

The environmental condition called vacuum is created any time the pressure of a gas is reduced compared to atmospheric pressure. On earth we typically create a vacuum by connecting a pump capable of moving gas to a relatively leak free vessel. Through operation of the gas pump the number of gas molecules per unit volume is decreased within the vessel. As soon as one creates a vacuum natural forces (in this case entropy) work to restore equilibrium pressure; the practical effect of this is that gas molecules attempt to enter the evacuated space by any means possible. It is useful to think of vacuum in terms of a gas at a pressure below atmospheric pressure. In even the best vacuum vessels ever created there are approximately 3,500,000 molecules of gas per cubic meter of volume remaining inside the vessel. The lowest pressure environment known is in interstellar space where there are approximately four molecules of gas per cubic meter. Researchers are currently developing vacuum technology components (pumps, gauges, valves, etc.) using micro electro mechanical systems (MEMS) technology. Miniature vacuum components and systems will open the possibility for significant savings in energy cost and will open the doors to advances in electronics, manufacturing and semiconductor fabrication. In conclusion, an understanding of the basic principles of vacuum technology as presented in this summary is essential for the successful execution of all projects that involve vacuum technology. Using the principles described above, a practitioner of vacuum technology can design a vacuum system that will achieve the project requirements.

Slow Dynamics of Orbital Domains in Manganite Print Slow Dynamics of Orbital Domains in Manganite Print At the ALS, an international team of researchers has used low-energy coherent x rays to extract new knowledge about the correlated motion of groups of self-assembled, outer-lying electrons in the extremely complex electronic system found in manganites.

By controlling the properties of the incident x rays, the researchers were able to map the complexity of a "half-doped" manganite into a far-field speckle diffraction pattern to study the manganite's domain dynamics.

OBSERVED DAMPING OF THE SLOW MAGNETOACOUSTIC MODE  

SciTech Connect

Spectroscopic and stereoscopic imaging observations of slow magnetoacoustic wave propagation within a coronal loop are investigated to determine the decay length scale of the slow magnetoacoustic mode in three dimensions and the density profile within the loop system. The slow wave is found to have an e-folding decay length scale of 20,000{sup +4000}{sub -3000} km with a uniform density profile along the loop base. These observations place quantitative constraints on the modeling of wave propagation within coronal loops. Theoretical forward modeling suggests that magnetic field line divergence is the dominant damping factor and thermal conduction is insufficient, given the observed parameters of the coronal loop temperature, density, and wave mode period.

Transplanckian energy production and slow roll inflation  

E-Print Network (OSTI)

In this paper we investigate how the energy density due to a non-standard choice of initial vacuum affects the expansion of the universe during inflation. To do this we introduce source terms in the Friedmann equations making sure that we respect the relation between gravity and thermodynamics. We find that the energy production automatically implies a slow rolling cosmological constant. Hence we also conclude that there is no well defined value for the cosmological constant in the presence of sources. We speculate that a non-standard vacuum can provide slow roll inflation on its own.

SECONDARY NATURAL GAS RECOVERY IN THE APPALACHIAN BASIN: APPLICATION OF ADVANCED TECHNOLOGIES IN A FIELD DEMONSTRATION SITE, HENDERSON DOME, WESTERN PENNSYLVANIA  

SciTech Connect

The principal objectives of this project were to test and evaluate technologies that would result in improved characterization of fractured natural-gas reservoirs in the Appalachian Basin. The Bureau of Economic Geology (Bureau) worked jointly with industry partner Atlas Resources, Inc. to design, execute, and evaluate several experimental tests toward this end. The experimental tests were of two types: (1) tests leading to a low-cost methodology whereby small-scale microfractures observed in matrix grains of sidewall cores can be used to deduce critical properties of large-scale fractures that control natural-gas production and (2) tests that verify methods whereby robust seismic shear (S) waves can be generated to detect and map fractured reservoir facies. The grain-scale microfracture approach to characterizing rock facies was developed in an ongoing Bureau research program that started before this Appalachian Basin study began. However, the method had not been tested in a wide variety of fracture systems, and the tectonic setting of rocks in the Appalachian Basin composed an ideal laboratory for perfecting the methodology. As a result of this Appalachian study, a low-cost commercial procedure now exists that will allow Appalachian operators to use scanning electron microscope (SEM) images of thin sections extracted from oriented sidewall cores to infer the spatial orientation, relative geologic timing, and population density of large-scale fracture systems in reservoir sandstones. These attributes are difficult to assess using conventional techniques. In the Henderson Dome area, large quartz-lined regional fractures having N20E strikes, and a subsidiary set of fractures having N70W strikes, are prevalent. An innovative method was also developed for obtaining the stratigraphic and geographic tops of sidewall cores. With currently deployed sidewall coring devices, no markings from which top orientation can be obtained are made on the sidewall core itself during drilling. The method developed in this study involves analysis of the surface morphology of the broken end of the core as a top indicator. Together with information on the working of the tool (rotation direction), fracture-surface features, such as arrest lines and plume structures, not only give a top direction for the cores but also indicate the direction of fracture propagation in the tough, fine-grained Cataract/Medina sandstones. The study determined that microresistivity logs or other image logs can be used to obtain accurate sidewall core azimuths and to determine the precise depths of the sidewall cores. Two seismic S-wave technologies were developed in this study. The first was a special explosive package that, when detonated in a conventional seismic shot hole, produces more robust S-waves than do standard seismic explosives. The importance of this source development is that it allows S-wave seismic data to be generated across all of the Appalachian Basin. Previously, Appalachian operators have not been able to use S-wave seismic technology to detect fractured reservoirs because the industry-standard S-wave energy source, the horizontal vibrator, is not a practical source option in the heavy timber cover that extends across most of the basin. The second S-wave seismic technology that was investigated was used to verify that standard P-wave seismic sources can create robust downgoing S-waves by P-to-S mode conversion in the shallow stratigraphic layering in the Appalachian Basin. This verification was done by recording and analyzing a 3-component vertical seismic profile (VSP) in the Atlas Montgomery No. 4 well at Henderson Dome, Mercer County, Pennsylvania. The VSP data confirmed that robust S-waves are generated by P-to-S mode conversion at the basinwide Onondaga stratigraphic level. Appalachian operators can thus use converted-mode seismic technology to create S-wave images of fractured and unfractured rock systems throughout the basin.

Barriers to the development of China's shale gas industry  

Science Journals Connector (OSTI)

Abstract Shale gas has become a promising onshore energy prospect in China. As much as the country aspires for greater energy independence through the use of its shale gas reserves, this process is slowed down by the combined weight of relative inexperience, lack of technology, geographical complexity, a hostile economic environment, a disincentive pipeline regime, and a complex land ownership system. To foster a better understanding of the current circumstances of the country's shale gas sector, a panel of scholars and experts shared their perspectives and insider knowledge on China's shale gas industry. It was found that some of the country's man-made institutional barriers are factors that have been hindering shale gas development in China, in addition to natural conditions such as water concerns and the complex geography of shale fields. Resolving this situation necessitates breaking the monopoly that major state-owned oil companies have over high-quality shale gas resources, opening pipeline network access, providing geological data, developing the domestic oil service market, creating conditions for fair competition between service providers, and improving the water management system.

Large Scale U.S. Unconventional Fuels Production and the Role of Carbon Dioxide Capture and Storage Technologies in Reducing Their Greenhouse Gas Emissions  

SciTech Connect

This paper examines the role that carbon dioxide capture and storage technologies could play in reducing greenhouse gas emissions if a significant unconventional fuels industry were to develop within the United States. Specifically, the paper examines the potential emergence of a large scale domestic unconventional fuels industry based on oil shale and coal-to-liquids (CTL) technologies. For both of these domestic heavy hydrocarbon resources, this paper models the growth of domestic production to a capacity of 3 MMB/d by 2050. For the oil shale production case, we model large scale deployment of an in-situ retorting process applied to the Eocene Green River formation of Colorado, Utah, and Wyoming where approximately 75% of the high grade oil shale resources within the United States lies. For the CTL case, we examine a more geographically dispersed coal-based unconventional fuel industry. This paper examines the performance of these industries under two hypothetical climate policies and concludes that even with the wide scale availability of cost effective carbon dioxide capture and storage technologies, these unconventional fuels production industries would be responsible for significant increases in CO2 emissions to the atmosphere. The oil shale production facilities required to produce 3MMB/d would result in net emissions to the atmosphere of between 3000-7000 MtCO2 in addition to storing potentially 1000 to 5000 MtCO2 in regional deep geologic formations in the period up to 2050. A similarly sized domestic CTL industry could result in 4000 to 5000 MtCO2 emitted to the atmosphere in addition to potentially 21,000 to 22,000 MtCO2 stored in regional deep geologic formations over the same period up to 2050. Preliminary analysis of regional CO2 storage capacity in locations where such facilities might be sited indicates that there appears to be sufficient storage capacity, primarily in deep saline formations, to accommodate the CO2 from these industries. However, additional analyses plus detailed regional and site characterization is needed, along with a closer examination of competing storage demands.

Scattering of Slow Neutrons by Water  

Science Journals Connector (OSTI)

The motions of hydrogen atoms in water are considered in terms of the H2O molecule at the basic dynamical unit. Vibrations, hindered rotations, and translations of the molecule are included. For the numerical calculations, the hindrance of the translations is neglected, and the hindered rotations are replaced by a torsional oscillation with a single energy, h?=0.06 ev. When certain approximations are made in the average over molecular orientation, this model allows for the computation of differential and total slow-neutron cross sections. The computed cross sections are in good agreement with most of the available slow-neutron scattering data. The features of the high-resolution experiments directly associated with the hindrance of the molecular translations in the liquid are not reproduced.

Intermediate Scattering Function in Slow Neutron Scattering  

Science Journals Connector (OSTI)

The conditions under which the so-called intermediate scattering function occurring in the theory of slow neutron scattering and in the theory of the Mössbauer effect can be written in the form exp[-?2?(t)] have been explicitly stated; the intermediate scattering function is then factorizable into two parts; the part referred to in the paper as the displacement part gives on Fourier transformation a real space-time function which, quite unambiguously, has the meaning usually attributed to the Van Hove Gs(x, t) function; the other part arises out of the nucleus recoiling against the neutron. It is shown that for systems in thermal equilibrium, the recoil part can be expressed in terms of the displacement part. This relation enables one to take care of the recoil part in case a classical approximation is made for the dynamics of the scattering system.

Phase sensitivity of slow electrons to interactions with weak potentials  

SciTech Connect

The interaction of very slow electrons with weak potentials is investigated in an exactly soluble, one-dimensional quantum mechanical model. Slow electrons are produced by a decelerating ramp potential, as in experimental mirror electron microscopy, so the electrons can interact with a weak field as they slow and reverse direction. Our model provides a wave mechanical interpretation of this turning point region and suggests the possibility of imaging optical fields utilizing the phase of electron matter waves.

Electric power generation using a phosphoric acid cell on a municipal solid waste landfill gas stream. Technology verification report, November 1997--July 1998  

SciTech Connect

The report gives results of tests to verify the performance of a landfill gas pretreatment unit (GPU) and a phosphoric acid fuel cell system. The complete system removes contaminants from landfill gas and produces electricity for on-site use or connection to an electric grid. Performance data were collected at two sites determined to be representative of the U.S. landfill market. The Penrose facility, in Los Angeles, CA, was the first test site. The landfill gas at this site represented waste gas recovery from four nearby landfills, consisting primarily of industrial waste material. It produced approximately 3000 scf of gas/minute, and had a higher heating value of 446 Btu/scf at about 44% methane concentration. The second test site, in Groton, CT, was a relatively small landfill, but with greater heat content gas (methane levels were about 57% and the average heating value was 585 Btu/scf). The verification test addressed contaminant removal efficiency, flare destruction efficiency, and the operational capability of the cleanup system, and the power production capability of the fuel cell system.

Slow-Neutron Scattering by Molecules  

Science Journals Connector (OSTI)

The operator formalism in slow-neutron scattering theory introduced by Wick and by Zemach and Glauber is considered in an approximation in which molecular rotational and vibrational effects are explicitly separated. The combined effects of rotation and translation are treated in terms of the Sachs-Teller "mass-tensor" concept, which is rederived on the basis of a rigid molecule Hamiltonian and extended to include interference effects. Only elastic vibrational transitions from the ground vibrational state are considered. The applicable neutron energy range is restricted to values large compared to the rotational level separation but below the vibrational threshold.The method is applicable to the calculation of differential as well as total scattering cross sections and to molecules of arbitrary structure. Expressions in closed form for these cross sections are obtained through use of an approximate procedure for averaging over molecular orientations. In the case of hydrogenous molecules, where direct scattering is dominant, the scattering by a given nucleus is described in terms of two parameters, viz., an effective nuclear mass for rotation and translation, and a vibrational constant. The relative simplicity of the method is illustrated in the calculation of the differential and total cross sections of CH4 and the total cross section of H2. Agreement of these calculations with experiment and with other calculations is good.

Where the offshore search for oil and gas is headed  

SciTech Connect

This overview of the world's potential offshore oil and gas frontiers points out that although solutions to technical and political problems have opened up some promising areas for exploration, many key frontier basins have yet to be explored by modern technology. Long-standing disputes between bordering countries over offshore rights have deterred exploration activities in the Malvinas basin off Argentina and in the Gulf of Venezuela. Political problems have also slowed activity in the US Atlantic offshore, where Mesozoic reef trends may be related to Mexico's large oil fields. In Canada's Labrador Sea and Grand Banks, the problems are largely operational because of the inclement weather and threatening icebergs. The thick sediments off northern Norway remain untapped due to the deep water, Arctic conditions, and boundary disputes with the USSR. The main areas of active exploration are the Gulf of Thailand-Penyu-Natuna basin in Southeast Asia and Ireland's Porcupine Bight basin.

The NEXT experiment: A high pressure xenon gas TPC for neutrinoless double beta decay searches  

E-Print Network (OSTI)

Neutrinoless double beta decay is a hypothetical, very slow nuclear transition in which two neutrons undergo beta decay simultaneously and without the emission of neutrinos. The importance of this process goes beyond its intrinsic interest: an unambiguous observation would establish a Majorana nature for the neutrino and prove the violation of lepton number. NEXT is a new experiment to search for neutrinoless double beta decay using a radiopure high-pressure xenon gas TPC, filled with 100 kg of Xe enriched in Xe-136. NEXT will be the first large high-pressure gas TPC to use electroluminescence readout with SOFT (Separated, Optimized FuncTions) technology. The design consists in asymmetric TPC, with photomultipliers behind a transparent cathode and position-sensitive light pixels behind the anode. The experiment is approved to start data taking at the Laboratorio Subterr\\'aneo de Canfranc (LSC), Spain, in 2014.

Compressed natural gas measurement issues  

SciTech Connect

The Natural Gas Vehicle Coalition`s Measurement and Metering Task Group (MMTG) was established on July 1st, 1992 to develop suggested revisions to National Institute of Standards & Technology (NIST) Handbook 44-1992 (Specifications, Tolerances, and Other Technical Requirements for Weighing and Measuring Devices) and NIST Handbook 130-1991 (Uniform Laws & Regulations). Specifically, the suggested revisions will address the sale and measurement of compressed natural gas when sold as a motor vehicle fuel. This paper briefly discusses the activities of the MMTG and its interaction with NIST. The paper also discusses the Institute of Gas Technology`s (IGT) support of the MMTG in the area of natural gas composition, their impact on metering technology applicable to high pressure fueling stations as well as conversion factors for the establishment of ``gallon gasoline equivalent`` of natural gas. The final portion of this paper discusses IGT`s meter research activities and its meter test facility.

Lead Slowing Down Spectrometer FY2013 Annual Report  

SciTech Connect

Executive Summary The Lead Slowing Down Spectrometry (LSDS) project, funded by the Materials Protection And Control Technology campaign, has been evaluating the feasibility of using LSDS techniques to assay fissile isotopes in used nuclear fuel assemblies. The approach has the potential to provide considerable improvement in the assay of fissile isotopic masses in fuel assemblies compared to other non-destructive techniques in a direct and independent manner. This report is a high level summary of the progress completed in FY2013. This progress included: • Fabrication of a 4He scintillator detector to detect fast neutrons in the LSDS operating environment. Testing of the detector will be conducted in FY2014. • Design of a large area 232Th fission chamber. • Analysis using the Los Alamos National Laboratory perturbation model estimated the required number of neutrons for an LSDS measurement to be 10 to the 16th source neutrons. • Application of the algorithms developed at Pacific Northwest National Laboratory to LSDS measurement data of various fissile samples conducted in 2012. The results concluded that the 235U could be measured to 2.7% and the 239Pu could be measured to 6.3%. Significant effort is yet needed to demonstrate the applicability of these algorithms for used-fuel assemblies, but the results reported here are encouraging in demonstrating that we are making progress toward that goal. • Development and cost-analysis of a research plan for the next critical demonstration measurements. The plan suggests measurements on fresh fuel sub assemblies as a means to experimentally test self-attenuation and the use of fresh mixed-oxide fuel as a means to test simultaneous measurement of 235U and 239Pu.

In-Situ Measurements of Low Enrichment Uranium Holdup Process Gas Piping at K-25 - Paper for Waste Management Symposia 2010 East Tennessee Technology Park Oak Ridge, Tennessee  

SciTech Connect

This document is the final version of a paper submitted to the Waste Management Symposia, Phoenix, 2010, abstract BJC/OR-3280. The primary document from which this paper was condensed is In-Situ Measurement of Low Enrichment Uranium Holdup in Process Gas Piping at K-25 Using NaI/HMS4 Gamma Detection Systems, BJC/OR-3355. This work explores the sufficiency and limitations of the Holdup Measurement System 4 (HJVIS4) software algorithms applied to measurements of low enriched uranium holdup in gaseous diffusion process gas piping. HMS4 has been used extensively during the decommissioning and demolition project of the K-25 building for U-235 holdup quantification. The HMS4 software is an integral part of one of the primary nondestructive assay (NDA) systems which was successfully tested and qualified for holdup deposit quantification in the process gas piping of the K-25 building. The initial qualification focused on the measurement of highly enriched UO{sub 2}F{sub 2} deposits. The purpose of this work was to determine if that qualification could be extended to include the quantification of holdup in UO{sub 2}F{sub 2} deposits of lower enrichment. Sample field data are presented to provide evidence in support of the theoretical foundation. The HMS4 algorithms were investigated in detail and found to sufficiently compensate for UO{sub 2}F{sub 2} source self-attenuation effects, over the range of expected enrichment (4-40%), in the North and East Wings of the K-25 building. The limitations of the HMS4 algorithms were explored for a described set of conditions with respect to area source measurements of low enriched UO{sub 2}F{sub 2} deposits when used in conjunction with a 1 inch by 1/2 inch sodium iodide (NaI) scintillation detector. The theoretical limitations of HMS4, based on the expected conditions in the process gas system of the K-25 building, are related back to the required data quality objectives (DQO) for the NBA measurement system established for the K-25 demolition project. The combined review of the HMS software algorithms and supporting field measurements lead to the conclusion that the majority of process gas pipe measurements are adequately corrected for source self-attenuation using HMS4. While there will be instances where the UO{sub 2}F{sub 2} holdup mass presents an infinitely thick deposit to the NaI-HMS4 system these situations are expected to be infrequent. This work confirms that the HMS4 system can quantify UO{sub 2}F{sub 2} holdup, in its current configuration (deposition, enrichment, and geometry), below the DQO levels for the K-25 building decommissioning and demolition project. For an area measurement of process gas pipe in the K-25 building, if an infinitely thick UO{sub 2}F{sub 2} deposit is identified in the range of enrichment of {approx}4-40%, the holdup quantity exceeds the corresponding DQO established for the K-25 building demolition project.

Life-cycle analysis of shale gas and natural gas.  

SciTech Connect

The technologies and practices that have enabled the recent boom in shale gas production have also brought attention to the environmental impacts of its use. Using the current state of knowledge of the recovery, processing, and distribution of shale gas and conventional natural gas, we have estimated up-to-date, life-cycle greenhouse gas emissions. In addition, we have developed distribution functions for key parameters in each pathway to examine uncertainty and identify data gaps - such as methane emissions from shale gas well completions and conventional natural gas liquid unloadings - that need to be addressed further. Our base case results show that shale gas life-cycle emissions are 6% lower than those of conventional natural gas. However, the range in values for shale and conventional gas overlap, so there is a statistical uncertainty regarding whether shale gas emissions are indeed lower than conventional gas emissions. This life-cycle analysis provides insight into the critical stages in the natural gas industry where emissions occur and where opportunities exist to reduce the greenhouse gas footprint of natural gas.

Improved gas mixtures for gas-filled radiation detectors  

DOE Patents (OSTI)

Improved binary and ternary gas mixtures for gas-filled radiation detectors are provided. The components are chosen on the basis of the principle that the first component is one molecular gas or mixture of two molecular gases having a large electron scattering cross section at energies of about 0.5 eV and higher, and the second component is a noble gas having a very small cross section at and below about 1.0 eV, whereby fast electrons in the gaseous mixture are slowed into the energy range of about 0.5 eV where the cross section for the mixture is small and hence the electron mean free path is large. The reduction in both the cross section and the electron energy results in an increase in the drift velocity of the electrons in the gas mixtures over that for the separate components for a range of E/P (pressure-reduced electric field) values. Several gas mixtures are provided that provide faster response in gas-filled detectors for convenient E/P ranges as compared with conventional gas mixtures.

The U-GAS technology is presently available for licensing from GDC, Inc., a wholly-owned subsidiary of IGT. The U-GAS process accomplishes four important functions in a single-stage, fluidized-bed gasifier: It decakes coal, devolatilizes coal, gasifies coal, and agglomerates and separates ash from char. Simultaneously with coal gasification, the ash is agglomerated into spherical particles and separated from the bed. Part of the fluidizing gas enters the gasifier through a sloping grid. The remaining gas flows upward at a high velocity through the ash agglomerating device and forms a hot zone within the fluidized bed. High-ash-content particles agglomerate under these conditions and grow into larger and heavier particles. Agglomerates grow in size until they can be selectively separated and discharged from the bed into water-filled ash hoppers where they are withdrawn as a slurry. In this manner, the fluidized bed achieves the same low level of carbon losses in the discharge ash generally associated with the ash-slagging type of gasifier. Coal fines elutriated from the fluidized bed are collected in two external cyclones. Fines from the first cyclone are returned to the bed and fines from the second cyclone are returned to the ash agglomerating zone, where they are gasified, and the ash agglomerated with bed ash. The raw product gas is virtually free of tar and oils, thus simplifying ensuing heat recovery and purification steps.

PRESSURE ACTIVATED SEALANT TECHNOLOGY  

SciTech Connect

The objective of this project is to develop new, efficient, cost effective methods of internally sealing natural gas pipeline leaks through the application of differential pressure activated sealants. In researching the current state of the art for gas pipeline sealing technologies we concluded that if the project was successful, it appeared that pressure activated sealant technology would provide a cost effective alternative to existing pipeline repair technology. From our analysis of current field data for a 13 year period from 1985 to 1997 we were able to identify 205 leaks that were candidates for pressure activated sealant technology, affirming that pressure activated sealant technology is a viable option to traditional external leak repairs. The data collected included types of defects, areas of defects, pipe sizes and materials, incident and operating pressures, ability of pipeline to be pigged and corrosion states. This data, and subsequent analysis, was utilized as a basis for constructing applicable sealant test modeling.

CO2-Binding Organic Liquids Gas Capture with Polarity-Swing-Assisted Regeneration Full Technology Feasibility Study B1 - Solvent-based Systems  

SciTech Connect

PNNL, Fluor Corporation and Queens University (Kingston, ON) successfully completed a three year comprehensive study of the CO2BOL water-lean solvent platform with Polarity Swing Assisted Regeneration (PSAR). This study encompassed solvent synthesis, characterization, environmental toxicology, physical, thermodynamic and kinetic property measurements, Aspen Plus™ modeling and bench-scale testing of a candidate CO2BOL solvent molecule. Key Program Findings The key program findings are summarized as follows: • PSAR favorably reduced stripper duties and reboiler temperatures with little/no impact to absorption column • >90% CO2 capture was achievable at reasonable liquid-gas ratios in the absorber • High rich solvent viscosities (up to 600 cP) were successfully demonstrated in the bench-scale system. However, the projected impacts of high viscosity to capital cost and operational limits compromised the other levelized cost of electricity benefits. • Low thermal conductivity of organics significantly increased the required cross exchanger surface area, and potentially other heat exchange surfaces. • CO2BOL had low evaporative losses during bench-scale testing • There was no evidence of foaming during bench scale testing • Current CO2BOL formulation costs project to be $35/kg • Ecotoxicity (Water Daphnia) was comparable between CO2BOL and MEA (169.47 versus 103.63 mg/L) • Full dehydration of the flue gas was determined to not be economically feasible. However, modest refrigeration (13 MW for the 550 MW reference system) was determined to be potentially economically feasible, and still produce a water-lean condition for the CO2BOLs (5 wt% steady-state water loading). • CO2BOLs testing with 5 wt% water loading did not compromise anhydrous performance behavior, and showed actual enhancement of CO2 capture performance. • Mass transfer of CO2BOLs was not greatly impeded by viscosity • Facile separation of antisolvent from lean CO2BOL was demonstrated on the bench cart • No measurable solvent degradation was observed over 4 months of testing – even with 5 wt% water present

Fluid-Bed Testing of Greatpoint Energy's Direct Oxygen Injection Catalytic Gasification Process for Synthetic Natural Gas and Hydrogen Coproduction Year 6 - Activity 1.14 - Development of a National Center for Hydrogen Technology  

SciTech Connect

The GreatPoint Energy (GPE) concept for producing synthetic natural gas and hydrogen from coal involves the catalytic gasification of coal and carbon. GPE’s technology “refines” coal by employing a novel catalyst to “crack” the carbon bonds and transform the coal into cleanburning methane (natural gas) and hydrogen. The GPE mild “catalytic” gasifier design and operating conditions result in reactor components that are less expensive and produce pipeline-grade methane and relatively high purity hydrogen. The system operates extremely efficiently on very low cost carbon sources such as lignites, subbituminous coals, tar sands, petcoke, and petroleum residual oil. In addition, GPE’s catalytic coal gasification process eliminates troublesome ash removal and slagging problems, reduces maintenance requirements, and increases thermal efficiency, significantly reducing the size of the air separation plant (a system that alone accounts for 20% of the capital cost of most gasification systems) in the catalytic gasification process. Energy & Environmental Research Center (EERC) pilot-scale gasification facilities were used to demonstrate how coal and catalyst are fed into a fluid-bed reactor with pressurized steam and a small amount of oxygen to “fluidize” the mixture and ensure constant contact between the catalyst and the carbon particles. In this environment, the catalyst facilitates multiple chemical reactions between the carbon and the steam on the surface of the coal. These reactions generate a mixture of predominantly methane, hydrogen, and carbon dioxide. Product gases from the process are sent to a gas-cleaning system where CO{sub 2} and other contaminants are removed. In a full-scale system, catalyst would be recovered from the bottom of the gasifier and recycled back into the fluid-bed reactor. The by-products (such as sulfur, nitrogen, and CO{sub 2}) would be captured and could be sold to the chemicals and petroleum industries, resulting in near-zero hazardous air or water pollution. This technology would also be conducive to the efficient coproduction of methane and hydrogen while also generating a relatively pure CO{sub 2} stream suitable for enhanced oil recovery (EOR) or sequestration. Specific results of bench-scale testing in the 4- to 38-lb/hr range in the EERC pilot system demonstrated high methane yields approaching 15 mol%, with high hydrogen yields approaching 50%. This was compared to an existing catalytic gasification model developed by GPE for its process. Long-term operation was demonstrated on both Powder River Basin subbituminous coal and on petcoke feedstocks utilizing oxygen injection without creating significant bed agglomeration. Carbon conversion was greater than 80% while operating at temperatures less than 1400°F, even with the shorter-than-desired reactor height. Initial designs for the GPE gasification concept called for a height that could not be accommodated by the EERC pilot facility. More gas-phase residence time should allow the syngas to be converted even more to methane. Another goal of producing significant quantities of highly concentrated catalyzed char for catalyst recovery and material handling studies was also successful. A Pd–Cu membrane was also successfully tested and demonstrated to produce 2.54 lb/day of hydrogen permeate, exceeding the desired hydrogen permeate production rate of 2.0 lb/day while being tested on actual coal-derived syngas that had been cleaned with advanced warm-gas cleanup systems. The membranes did not appear to suffer any performance degradation after exposure to the cleaned, warm syngas over a nominal 100-hour test.

Novel technologies for SO{sub x}/NO{sub x} removal from flue gas; Technical report, September 1--November 30, 1993  

SciTech Connect

The goal of this research is to develop a low temperature deNO{sub x} catalyst with activity high enough for boiler retrofit applications. Cu-ZrO{sub 2} is a promising low temperature catalyst for the selective reduction of No by propene. At NO = 1000 ppm, propene (C{sub 3}H{sub 6}) = 1000 ppm and 0{sub 2} = 1% and a space velocity of 13,000 h{sup {minus}1}, the NO conversion to N{sub 2} is 64% at 265{degrees}C. The performance of the catalyst, however, does not fulfill the requirement when used for flue gas clean up where the feed is composed of 4% O{sub 2} and 10% H{sub 2}O, and the temperature is 150{degrees}C. Methods to improve the performance of the catalyst are being sought. These include modification of the preparation method such as varying the aging time of the gel after precipitation, and addition of promoters like Pd and Nd to increase the catalytic activity at lower temperatures and higher 0{sub 2} concentrations. Using ethanol (C{sub 2}H{sub 5}OH) instead of C{sub 3}H{sub 6} as a reductant improves the performance of the catalyst when H{sub 2}O is present. Interestingly, methanol is not an effective reductant. Some modified carbon catalysts are also tested. Results on Cu impregnated ASC whetlerite carbon catalyst show 100% N{sub 2} selectivity and 35 % NO conversion at 200{degrees}C. However, the catalyst is unstable and deactivates rapidly. Work planned for the next quarter is to continue to investigate methods to improve the catalytic activity.

WABASH RIVER INTEGRATED METHANOL AND POWER PRODUCTION FROM CLEAN COAL TECHNOLOGIES (IMPPCCT)  

SciTech Connect

The Wabash River Integrated Methanol and Power Production from Clean Coal Technologies (IMPPCCT) project is evaluating integrated electrical power generation and methanol production through clean coal technologies. The project is conducted by a multi-industry team lead by Gasification Engineering Corporation (GEC), a company of Global Energy Inc., and supported by Air Products and Chemicals, Inc., Dow Chemical Company, Dow Corning Corporation, Methanex Corporation, and Siemens Westinghouse Power Corporation. Three project phases are planned for execution over a three year period, including: (1) Feasibility study and conceptual design for an integrated demonstration facility, and for fence-line commercial embodiment plants (CEP) operated at Dow Chemical or Dow Corning chemical plant locations (2) Research, development, and testing to define any technology gaps or critical design and integration issues (3) Engineering design and financing plan to install an integrated commercial demonstration facility at the existing Wabash River Energy Limited (WREL) plant in West Terre Haute, Indiana. The WREL facility is a project selected and co-funded under the Round IV of the U.S. Department of Energy's (DOE's) Clean Coal Technology Program. In this project, coal and/or other solid fuel feedstocks are gasified in an oxygen-blown, entrained-flow gasifier with continuous slag removal and a dry particulate removal system. The resulting product synthesis gas is used to fuel a combustion turbine generator whose exhaust is integrated with a heat recovery steam generator to drive a refurbished steam turbine generator. The gasifier uses technology initially developed by The Dow Chemical Company (the Destec Gasification Process), and now offered commercially by Global Energy, Inc., as the E-GAS{trademark} technology. In a joint effort with the DOE, a Cooperative Agreement was awarded under the Early Entrance Coproduction Plant (EECP) solicitation. GEC and an Industrial Consortium are investigating the use of synthesis gas produced by the E-GAS{trademark} technology in a coproduction environment to enhance the efficiency and productivity of solid fuel gasification combined cycle power plants. During the reporting period, various methods to remove low-level contaminants for the synthesis gas were reviewed. In addition, there was a transition of the project personnel for GEC which has slowed the production of the outstanding project reports.

A Model for the Sources of the Slow Solar Wind  

Science Journals Connector (OSTI)

Models for the origin of the slow solar wind must account for two seemingly contradictory observations: the slow wind has the composition of the closed-field corona, implying that it originates from the continuous opening and closing of flux at the boundary between open and closed field. On the other hand, the slow wind also has large angular width, up to ~60°, suggesting that its source extends far from the open-closed boundary. We propose a model that can explain both observations. The key idea is that the source of the slow wind at the Sun is a network of narrow (possibly singular) open-field corridors that map to a web of separatrices and quasi-separatrix layers in the heliosphere. We compute analytically the topology of an open-field corridor and show that it produces a quasi-separatrix layer in the heliosphere that extends to angles far from the heliospheric current sheet. We then use an MHD code and MDI/SOHO observations of the photospheric magnetic field to calculate numerically, with high spatial resolution, the quasi-steady solar wind, and magnetic field for a time period preceding the 2008 August 1 total solar eclipse. Our numerical results imply that, at least for this time period, a web of separatrices (which we term an S-web) forms with sufficient density and extent in the heliosphere to account for the observed properties of the slow wind. We discuss the implications of our S-web model for the structure and dynamics of the corona and heliosphere and propose further tests of the model.
