Ammonia synthesis gas purification  

SciTech Connect (OSTI)

This patent describes the purification of a reformed gas mixture following water gas shift conversion to produce a purified ammonia synthesis gas stream. The improved processing sequence consisting essentially of: (A) Selectively catalytically oxidizing the residual carbon monoxide content of the gas mixture to carbon dioxide so as to reduce the carbon monoxide content of the gas mixture to less than about 20 ppm, the selective catalytic oxidation being carried out with an excess of air, with the excess oxygen being catalytically reacted with a small amount of hydrogen so that the residual oxygen level is reduced to less than about 3 ppm; (B) removing the bulk of the carbon dioxide content of the gas mixture by liquid absorption; (C) Removing residual amounts of carbon monoxide, carbon dioxide and water by selective adsorption on the fixed beds of a thermal swing adsorption system, a dry, purified ammonia ammonia synthesis gas stream containing less than a total of 10 ppm of carbon monoxide and carbon dioxide being recovered from the thermal swing adsorption system; (D) Passing the resulting dry, purified ammonia synthesis gas stream having a low content of methane to an ammonia production operation without intermediate passage of the ammonia synthesis gas stream to a methanation unit or to a cryogenic unit for removal of carbon monoxide and carbon dioxide therefrom; whereby the efficiency of the overall purification operation and the effective utilization of hydrogen are enhanced.

Gas Storage Technology Consortium  

SciTech Connect (OSTI)

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.

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.

Natural gas pipeline technology overview.  

SciTech Connect (OSTI)

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.

Near-Zero Emissions Oxy-Combustion Flue Gas Purification Task 2: SOx/Nox/Hg Removal for High Sulfur Coal  

SciTech Connect (OSTI)

The goal of this project is to develop a near-zero emissions flue gas purification technology for existing PC (pulverized coal) power plants that are retrofitted with oxy-combustion technology. The objective of Task 2 of this project was to evaluate an alternative method of SOx, NOx and Hg removal from flue gas produced by burning high sulfur coal in oxy-combustion power plants. The goal of the program was not only to investigate a new method of flue gas purification but also to produce useful acid byproduct streams as an alternative to using a traditional FGD and SCR for flue gas processing. During the project two main constraints were identified that limit the ability of the process to achieve project goals. 1) Due to boiler island corrosion issues >60% of the sulfur must be removed in the boiler island with the use of an FGD. 2) A suitable method could not be found to remove NOx from the concentrated sulfuric acid product, which limits sale-ability of the acid, as well as the NOx removal efficiency of the process. Given the complexity and safety issues inherent in the cycle it is concluded that the acid product would not be directly saleable and, in this case, other flue gas purification schemes are better suited for SOx/NOx/Hg control when burning high sulfur coal, e.g. this project's Task 3 process or a traditional FGD and SCR.

Near-Zero Emissions Oxy-Combustion Flue Gas Purification  

SciTech Connect (OSTI)

The objectives of this project were to carry out an experimental program to enable development and design of near zero emissions (NZE) CO{sub 2} processing unit (CPU) for oxy-combustion plants burning high and low sulfur coals and to perform commercial viability assessment. The NZE CPU was proposed to produce high purity CO{sub 2} from the oxycombustion flue gas, to achieve > 95% CO{sub 2} capture rate and to achieve near zero atmospheric emissions of criteria pollutants. Two SOx/NOx removal technologies were proposed depending on the SOx levels in the flue gas. The activated carbon process was proposed for power plants burning low sulfur coal and the sulfuric acid process was proposed for power plants burning high sulfur coal. For plants burning high sulfur coal, the sulfuric acid process would convert SOx and NOx in to commercial grade sulfuric and nitric acid by-products, thus reducing operating costs associated with SOx/NOx removal. For plants burning low sulfur coal, investment in separate FGD and SCR equipment for producing high purity CO{sub 2} would not be needed. To achieve high CO{sub 2} capture rates, a hybrid process that combines cold box and VPSA (vacuum pressure swing adsorption) was proposed. In the proposed hybrid process, up to 90% of CO{sub 2} in the cold box vent stream would be recovered by CO{sub 2} VPSA and then it would be recycled and mixed with the flue gas stream upstream of the compressor. The overall recovery from the process will be > 95%. The activated carbon process was able to achieve simultaneous SOx and NOx removal in a single step. The removal efficiencies were >99.9% for SOx and >98% for NOx, thus exceeding the performance targets of >99% and >95%, respectively. The process was also found to be suitable for power plants burning both low and high sulfur coals. Sulfuric acid process did not meet the performance expectations. Although it could achieve high SOx (>99%) and NOx (>90%) removal efficiencies, it could not produce by-product sulfuric and nitric acids that meet the commercial product specifications. The sulfuric acid will have to be disposed of by neutralization, thus lowering the value of the technology to same level as that of the activated carbon process. Therefore, it was decided to discontinue any further efforts on sulfuric acid process. Because of encouraging results on the activated carbon process, it was decided to add a new subtask on testing this process in a dual bed continuous unit. A 40 days long continuous operation test confirmed the excellent SOx/NOx removal efficiencies achieved in the batch operation. This test also indicated the need for further efforts on optimization of adsorption-regeneration cycle to maintain long term activity of activated carbon material at a higher level. The VPSA process was tested in a pilot unit. It achieved CO{sub 2} recovery of > 95% and CO{sub 2} purity of >80% (by vol.) from simulated cold box feed streams. The overall CO{sub 2} recovery from the cold box VPSA hybrid process was projected to be >99% for plants with low air ingress (2%) and >97% for plants with high air ingress (10%). Economic analysis was performed to assess value of the NZE CPU. The advantage of NZE CPU over conventional CPU is only apparent when CO{sub 2} capture and avoided costs are compared. For greenfield plants, cost of avoided CO{sub 2} and cost of captured CO{sub 2} are generally about 11-14% lower using the NZE CPU compared to using a conventional CPU. For older plants with high air intrusion, the cost of avoided CO{sub 2} and capture CO{sub 2} are about 18-24% lower using the NZE CPU. Lower capture costs for NZE CPU are due to lower capital investment in FGD/SCR and higher CO{sub 2} capture efficiency. In summary, as a result of this project, we now have developed one technology option for NZE CPU based on the activated carbon process and coldbox-VPSA hybrid process. This technology is projected to work for both low and high sulfur coal plants. The NZE CPU technology is projected to achieve near zero stack emissions

Thermal-destruction products of coal in the blast-furnace gas-purification system  

SciTech Connect (OSTI)

The lean, poorly clinkering coal and anthracite used to replace coke in blast furnaces has a considerable content of volatile components (low-molecular thermaldestruction products), which enter the water and sludge of the blast-furnace gas-purification system as petroleum products. Therefore, it is important to study the influence of coal on the petroleum-product content in the water and sludge within this system. The liberation of primary thermal-destruction products is investigated for anthracite with around 4 wt % volatiles, using a STA 449C Jupiter thermoanalyzer equipped with a QMC 230 mass spectrometer. The thermoanalyzer determines small changes in mass and thermal effects with high accuracy (weighing accuracy 10{sup -8} g; error in measuring thermal effects 1 mV). This permits experiments with single layers of coal particles, eliminating secondary reactions of its thermal-destruction products.

Lithium bromide chiller technology in gas processing  

SciTech Connect (OSTI)

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.

Near-Zero Emissions Oxy-Combustion Flue Gas Purification - Power Plant Performance  

SciTech Connect (OSTI)

A technical feasibility assessment was performed for retrofitting oxy-fuel technology to an existing power plant burning low sulfur PRB fuel and high sulfur bituminous fuel. The focus of this study was on the boiler/power generation island of a subcritical steam cycle power plant. The power plant performance in air and oxy-firing modes was estimated and modifications required for oxy-firing capabilities were identified. A 460 MWe (gross) reference subcritical PC power plant was modeled. The reference air-fired plant has a boiler efficiency (PRB/Bituminous) of 86.7%/89.3% and a plant net efficiency of 35.8/36.7%. Net efficiency for oxy-fuel firing including ASU/CPU duty is 25.6%/26.6% (PRB/Bituminous). The oxy-fuel flue gas recirculation flow to the boiler is 68%/72% (PRB/bituminous) of the flue gas (average O{sub 2} in feed gas is 27.4%/26.4%v (PRB/bituminous)). Maximum increase in tube wall temperature is less than 10ÂşF for oxy-fuel firing. For oxy-fuel firing, ammonia injected to the SCR was shut-off and the FGD is applied to remove SOx from the recycled primary gas stream and a portion of the SOx from the secondary stream for the high sulfur bituminous coal. Based on CFD simulations it was determined that at the furnace outlet compared to air-firing, SO{sub 3}/SO{sub 2} mole ratio is about the same, NOx ppmv level is about the same for PRB-firing and 2.5 times for bituminous-firing due to shutting off the OFA, and CO mole fraction is approximately double. A conceptual level cost estimate was performed for the incremental equipment and installation cost of the oxyfuel retrofit in the boiler island and steam system. The cost of the retrofit is estimated to be approximately 81 M$ for PRB low sulfur fuel and 84 M$ for bituminous high sulfur fuel.

Near-Zero Emissions Oxy-Combustion Flue Gas Purification Task 3: SOx/NOx/Hg Removal for Low Sulfur Coal  

SciTech Connect (OSTI)

The goal of this project was to develop a near-zero emissions flue gas purification technology for existing PC (pulverized coal) power plants that are retrofitted with oxycombustion technology. The objective of Task 3 of this project was to evaluate an alternative method of SOx, NOx and Hg removal from flue gas produced by burning low sulfur coal in oxy-combustion power plants. The goal of the program was to conduct an experimental investigation and to develop a novel process for simultaneously removal of SOx and NOx from power plants that would operate on low sulfur coal without the need for wet-FGD & SCRs. A novel purification process operating at high pressures and ambient temperatures was developed. Activated carbonâ??s catalytic and adsorbent capabilities are used to oxidize the sulfur and nitrous oxides to SO{sub 3} and NO{sub 2} species, which are adsorbed on the activated carbon and removed from the gas phase. Activated carbon is regenerated by water wash followed by drying. The development effort commenced with the screening of commercially available activated carbon materials for their capability to remove SO{sub 2}. A bench-unit operating in batch mode was constructed to conduct an experimental investigation of simultaneous SOx and NOx removal from a simulated oxyfuel flue gas mixture. Optimal operating conditions and the capacity of the activated carbon to remove the contaminants were identified. The process was able to achieve simultaneous SOx and NOx removal in a single step. The removal efficiencies were >99.9% for SOx and >98% for NOx. In the longevity tests performed on a batch unit, the retention capacity could be maintained at high level over 20 cycles. This process was able to effectively remove up to 4000 ppm SOx from the simulated feeds corresponding to oxyfuel flue gas from high sulfur coal plants. A dual bed continuous unit with five times the capacity of the batch unit was constructed to test continuous operation and longevity. Full-automation was implemented to enable continuous operation (24/7) with minimum operator supervision. Continuous run was carried out for 40 days. Very high SOx (>99.9%) and NOx (98%) removal efficiencies were also achieved in a continuous unit. However, the retention capacity of carbon beds for SOx and NOx was decreased from ~20 hours to ~10 hours over a 40 day period of operation, which was in contrast to the results obtained in a batch unit. These contradictory results indicate the need for optimization of adsorption-regeneration cycle to maintain long term activity of activated carbon material at a higher level and thus minimize the capital cost of the system. In summary, the activated carbon process exceeded performance targets for SOx and NOx removal efficiencies and it was found to be suitable for power plants burning both low and high sulfur coals. More efforts are needed to optimize the system performance.

Flue Gas Purification Utilizing SOx/NOx Reactions During Compression of CO{sub 2} Derived from Oxyfuel Combustion  

SciTech Connect (OSTI)

The United States wishes to decrease foreign energy dependence by utilizing the country’s significant coal reserves, while stemming the effects of global warming from greenhouse gases. In response to these needs, Air Products has developed a patented process for the compression and purification of the CO{sub 2} stream from oxyfuel combustion of pulverized coal. The purpose of this project was the development and performance of a comprehensive experimental and engineering evaluation to determine the feasibility of purifying CO{sub 2} derived from the flue gas generated in a tangentially fired coal combustion unit operated in the oxy-combustion mode. Following the design and construction of a 15 bar reactor system, Air Products conducted two test campaigns using the slip stream from the tangentially fired oxy-coal combustion unit. During the first test campaign, Air Products evaluated the reactor performance based on both the liquid and gaseous reactor effluents. The data obtained from the test run has enabled Air Products to determine the reaction and mass transfer rates, as well as the effectiveness of the reactor system. During the second test campaign, Air Products evaluated reactor performance based on effluents for different reactor pressures, as well as water recycle rates. Analysis of the reaction equations indicates that both pressure and water flow rate affect the process reaction rates, as well as the overall reactor performance.

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).

HD is an attractive target since all of the material is polarizable, of low Z, and requires only modest holding #12;elds. At the same time, the small contributions from the target cell can be subtracted from direct measurements. Reaching the frozen-spin state with both high polarization and a signi#12;cant spin relaxation time requires careful control of H2 and D2 impurities. Commercially available HD contains 0.5 - 2% concentrations of H2 and D2. Low-temperature distillation is required to reduce these concentrations to the 10􀀀4 level to enable useful target production. This distillation is done using a column #12;lled with heli-pack C [4] to give good separation e#14;ciency. Approximately 12 moles of commercial HD is condensed into the mechanically refrigerated system at the base temperature of 11K. The system is then isolated and the temperature stabilized at 18K producing liquid HD, which is boiled by a resistive heater. The circulation established by the boil-o#11; condensing throughout the column then #12;ltering back down produces a steady-state isotopic separation permitting the extraction of HD gas with very low H2 and D2 content. A residual gas analyzer initially monitors distillation. Once the H2 concentration falls below its useful operating range, samples are periodically collected for analysis using gas chromatography [5] and Raman scattering. Where the measurement techniques overlap, good agreement is obtained. The operation of the distillery and results of gas analysis will be discussed. References [1] Phy. Rev. Lett. 101 (2009) 172002.

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.

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.

Mechanisms by Which Methane Gas and Methane Hydrate Coexist In Ocean Sediments Mechanisms by Which Methane Gas and Methane Hydrate Coexist In Ocean Sediments Mechanisms by Which Methane Gas and Methane Hydrate Coexist In Ocean Sediments Authors: Maša Prodanovic (speaker), Javad Behseresht, Yao Peng, Steven L. Bryant, Antone K. 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 (OSTI)

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.

Options for Gas-to-Liquids Technology in Alaska  

SciTech Connect (OSTI)

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.

New generation enrichment monitoring technology for gas centrifuge enrichment plants  

SciTech Connect (OSTI)

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.

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 (OSTI)

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 (OSTI)

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.

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.

Three initial water saturations were used to form three different methane hydrate saturations. X-ray computed tomography (CT) was used to observe location-specific density changes, caused by hydrate formation and flowing water. Gas permeability was measured in each test for dry sand, moist sand, frozen sand, and hydrate-bearing sand. Results of these measurements are presented. Water was flowed through the hydrate-bearing sand, and the changes in water saturation were observed using CT scanning. Inverse modeling will be performed using these data to extend the relative permeability measurements

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

DOE Technology Successes - "Breakthrough" Gas Turbines DOE Technology Successes - "Breakthrough" Gas Turbines DOE Technology Successes - "Breakthrough" Gas Turbines For years, gas turbine manufacturers faced a barrier that, for all practical purposes, capped power generating efficiencies for turbine-based power generating systems. 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. The Department of Energy's Office of Fossil Energy took on the challenge of turbine temperatures in 1992, and nine years later, its private sector

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.

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.

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.

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.

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

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.

SNO+ Scintillator Purification and Assay  

SciTech Connect (OSTI)

We describe the R and D on the scintillator purification and assay methods and technology for the SNO+ neutrino and double-beta decay experiment. The SNO+ experiment is a replacement of the SNO heavy water with liquid scintillator comprised of 2 g/L PPO in linear alkylbenzene (LAB). During filling the LAB will be transported underground by rail car and purified by multi-stage distillation and steam stripping at a flow rate of 19 LPM. While the detector is operational the scintillator can be recirculated at 150 LPM (full detector volume in 4 days) to provide repurification as necessary by either water extraction (for Ra, K, Bi) or by functional metal scavenger columns (for Pb, Ra, Bi, Ac, Th) followed by steam stripping to remove noble gases and oxygen (Rn, O{sub 2}, Kr, Ar). The metal scavenger columns also provide a method for scintillator assay for ex-situ measurement of the U and Th chain radioactivity. We have developed ''natural'' radioactive spikes of Pb and Ra in LAB and use these for purification testing. Lastly, we present the planned operating modes and purification strategies and the plant specifications and design.

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

SciTech Connect (OSTI)

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. Networking opportunities that occur with a Houston Headquarters (HQ) location are increasing name awareness. Focused efforts by Executive Director Don Duttlinger to interact with large independents, national service companies and some majors are continuing to supplement the support base of the medium to smaller industry participants around the country. PTTC is now involved in many of the technology-related activities that occur in high oil and natural gas activity areas. Access to technology remains the driving force for those who do not have in-house research and development capabilities and look to the PTTC to provide services and options for increased efficiency.

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

SciTech Connect (OSTI)

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 (OSTI)

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 (OSTI)

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.

Drilling Tests of an Active Vibration Damper Drilling Tests of an Active Vibration Damper Drilling Tests of an Active Vibration Damper Authors: Mark Wassell, Martin Cobern, Carl Perry, Jason Barbely, and Daniel Burgess, APS Technology, Inc. Venue: Drilling Engineering Association’s 2007 DEA Workshop in Galveston, TX, June 19-20, 2007 Abstract: Testing of an active drilling vibration damper (AVD) system at TerraTek Laboratory, under conditions designed to induce vibration, demonstrated that the use of the AVD reduced vibration, maintained more consistent weight-on-bit, and increased rate of penetration (ROP). These tests demonstrated that the AVD is likely to provide significant time and cost savings, particularly in deep wells. The results of these tests will be outlined. Related NETL Project: The goal of the related NETL project DE-FC26-02NT41664, “Drilling Vibration Monitoring and Control System,” is to improve ROP and reduce the incidence of premature equipment failures in deep hard rock drilling environments by reducing harmful drillstring vibration.

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

SciTech Connect (OSTI)

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.

Fine-Scale Control of Microbial Communities in Deep Marine Sediments Fine-Scale Control of Microbial Communities in Deep Marine Sediments Fine-Scale Control of Microbial Communities in Deep Marine Sediments that Contain Hydrates and High Concentrations of Methane Authors: Colwell, F. (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.

Ultra-high CO2 capture efficiency in CFB oxyfuel power plants by calcium looping process for CO2 recovery from purification units vent gas  

Science Journals Connector (OSTI)

Abstract This work presents a new option for the recovery of the CO2 losses from CO2 purification units in oxyfuel plants, by means of the Ca-looping process. The idea is to capture the CO2 in the vent stream from purification units by reaction with CaO sorbent in a carbonator reactor, where CaCO3 is formed. Sorbent is then regenerated in a calciner reactor by oxyfuel combustion of a fraction of the coal fed to the power plant. Since the Ca-looping process requires a continuous purge of exhaust sorbent and make-up of fresh limestone, the system is best coupled with a CFB boiler, where the exhausted Ca-rich sorbent can be used for in-furnace sulfur absorption. In this work, detailed mass and energy balances of the system proposed are reported, including a preliminary sizing of the reactors of the Ca-looping unit. A sensitivity analysis was also performed, by considering two types of coal as feed (mainly differing in sulfur content), two levels of non-condensable gases in the impure CO2 stream to be purified and different behaviors of the exhausted Ca-based sorbent injected in the CFB boiler, where it can experience different levels of recarbonation. Interesting results were obtained for this new system, which can capture about 90% of the CO2 vented from the purification unit in a reasonably compact reactors system, allowing an overall CO2 avoidance of the order of 99% with respect to conventional coal-fired steam plants without capture. As far as energy penalties are concerned, they were evaluated by the specific primary energy consumption for CO2 avoided index (SPECCA). Small differences with respect to reference oxyfuel plants without CO2 recovery were obtained, with either slightly better or slightly worse performances, depending on the sulfur content of the coal used. Penalties are associated to the export of CaO in the final exhausted sulfated sorbent from the CFB boiler, which increases when a higher sulfur coal is used. However, experimental analysis on the recarbonation level which can be attained by the CaL exhaust sorbent in the CFB boiler and further process optimization are needed to correctly account for these penalties and possibly minimize them.

Multivariate Modeling of 3D9C Data for Constructing a Static Reservoir Model of Algal Mounds in the Paradox Basin, CO Multivariate Modeling of 3D9C Data for Constructing a Static Reservoir Model of Algal Mounds in the Paradox Basin, CO Multivariate Modeling of 3D9C Data for Constructing a Static Reservoir Model of Algal Mounds in the Paradox Basin, CO Authors: Paul La Pointe, FracMan Technology Group, Golder Associates Inc., Redmond, WA; Robert D. 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 (OSTI)

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.

Hydrogen Production and Purification from Coal and Other Heavy Feedstocks Year 6 - Activity 1.4 - Development of a National Center for Hydrogen Technology  

SciTech Connect (OSTI)

Air Products and Chemicals, Inc., is developing the sour pressure swing adsorption (PSA) technology which can be used to reject acid gas components (hydrogen sulfide [H{sub 2}S] and carbon dioxide [CO{sub 2}]) from sour syngas streams such as coal gasification syngas. In the current work, tests were conducted to investigate the impact of continuous exposure of real sour syngas and dilute levels of hydrochloric acid (HCl) and ammonia (NH{sub 3}) on the preferred adsorbent of that process. The results show a modest (~10%–15%) decrease in CO{sub 2} adsorption capacity after sour syngas exposure, as well as deposition of metals from carbonyl decomposition. Continuous exposure to HCl and NH{sub 3} yield a higher degree of CO{sub 2} capacity degradation (up to 25%). These tests represent worst-case approaches since the exposure is continuous and the HCl and NH{sub 3} levels are relatively high compare to an industrial sour syngas stream. Long-term PSA tests are needed to unequivocally evaluate the impact of cyclic exposure to these types of streams.

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

SciTech Connect (OSTI)

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 (OSTI)

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.

Technology-Based Technology-Based Oil and Natural Gas Plays: Shale Shock! Could There Be Billions in the Bakken? Through the use of technology, U.S. oil and natural gas operators are converting previously uneconomic oil and natural gas resources into proved reserves and production. 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. In short, it came from using technology

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.

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.

SciTech Connect (OSTI)

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.

U-GAS process  

SciTech Connect (OSTI)

The Institute of Gas Technology (IGT) has developed an advanced coal gasification process. The U-GAS process has been extensively tested in a pilot plant to firmly establish process feasibility and provide a large data base for scale-up and design of the first commercial plant. The U-GAS process is considered to be one of the more flexible, efficient, and economical coal gasification technologies developed in the US during the last decade. 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.

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 (OSTI)

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 (OSTI)

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.

Probabilistic theories with purification  

SciTech Connect (OSTI)

We investigate general probabilistic theories in which every mixed state has a purification, unique up to reversible channels on the purifying system. We show that the purification principle is equivalent to the existence of a reversible realization of every physical process, that is, to the fact that every physical process can be regarded as arising from a reversible interaction of the system with an environment, which is eventually discarded. From the purification principle we also construct an isomorphism between transformations and bipartite states that possesses all structural properties of the Choi-Jamiolkowski isomorphism in quantum theory. Such an isomorphism allows one to prove most of the basic features of quantum theory, like, e.g., existence of pure bipartite states giving perfect correlations in independent experiments, no information without disturbance, no joint discrimination of all pure states, no cloning, teleportation, no programming, no bit commitment, complementarity between correctable channels and deletion channels, characterization of entanglement-breaking channels as measure-and-prepare channels, and others, without resorting to the mathematical framework of Hilbert spaces.

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

SciTech Connect (OSTI)

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 (OSTI)

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 (OSTI)

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.

16 - Nanotechnology for domestic water purification  

Science Journals Connector (OSTI)

Abstract: Water, a nonsubstitutional natural resource, is best described by Leonardo Da Vinci as ‘the vehicle of nature’ (‘vetturale di natura’). This is the single most essential commodity responsible for the existence and sustenance of life on the planet earth. It is not at all an exaggeration to state that water is primarily responsible for the restoration of health, environment and prosperiy of human civilization. Unfortunately, this most precious natural resource is becoming increasingly scarce day by day. Water scarcity is among the main problems facing many societies around the world in the twenty-first century. Water use has been growing at more than twice the rate of population increase in the last century. According to a report from the United Nations, by 2025, 1800 million people will be living in countries or regions with absolute water scarcity, and two-thirds of the world’s population could be under stress conditions. As emphasized in one of the UN’s Millenium Development Goals (MDGs), water scarcity calls for strengthened international cooperation in the fields of technologies for enhanced water productivity. Recent years have witnessed impressive breakthroughs towards application of nanostructured materials such as carbon nanotubes (CNTs), metal/metal-oxide nanoparticles, zeolites, and dendrimers in the field of water purification. The present chapter aims to give an overview of the developments in the application of nanotechnology in water treatment, with a special emphasis on domestic water purification. The focus is oriented to the fact that the ultimate practical realization of this new technology is based on the assessment of the risks as well as benefits posed by nanostructured materials. The challenges involved in producing a well-defined integrated nano-based water purification device are discussed.

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 (OSTI)

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 (OSTI)

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 (OSTI)

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 (OSTI)

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 (OSTI)

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 (OSTI)

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.

Water Purification Using the Adsorption Characteristics of Microbubbles  

Science Journals Connector (OSTI)

Recently, technology using microbubbles has been studied for water purification. However, the mechanism and physical parameters of the purification process have not yet been sufficiently clarified. The purpose of this study is to clarify the physical parameters of microbubbles that influence water purification. Firstly, we measured and analyzed the purifying performance using various millimeter-sized bubbles, and we obtained the equilibrium constant of the pollutant adsorbed on the bubble surface from the experimental results. Secondly, we experimented with purifying the polluted water using microbubbles and clarified that the purification performance of microbubbles agreed with that theoretically expected using the equilibrium constant obtained in the preparatory experiment. We assume that an important parameter affecting adsorption on the surface of microbubbles is the equilibrium constant in the chemical potential. Because the equilibrium constant is derived from the surface chemical potential, it is equal to the bulk chemical potential of the liquid. In the microbubbles diameter (70 µm) range in this study, we have found that the most significant factor determining the adsorption is the surface area. The surface tension of microbubbles is not significant factor.

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

SciTech Connect (OSTI)

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

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

SciTech Connect (OSTI)

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 (OSTI)

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.

Jain and Ruben Juanes Venue: International Conference on Gas Hydrates, Vancouver, Canada, July 7-10, 2008. ( http://www.icgh.org [external site] ) Abstract: Methane hydrates in ocean sediments range from essentially static accumulations of hydrate and brine, 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 (Behseresht, Prodanovic and Bryant) methods are described 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. H A discrete element method (DEM) is presented to model the strong coupling that takes place between the pore fluids and the mechanical behavior of the sediment.

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

SciTech Connect (OSTI)

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 (OSTI)

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 (OSTI)

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.

Purification of noisy quantum measurements  

SciTech Connect (OSTI)

We consider the problem of improving noisy quantum measurements by suitable preprocessing strategies making many noisy detectors equivalent to a single ideal detector. For observables pertaining to finite-dimensional systems (e.g., qubits or spins) we consider preprocessing strategies that are reminiscent of quantum error correction procedures and allow one to perfectly measure an observable on a single quantum system for increasing number of inefficient detectors. For measurements of observables with an unbounded spectrum (e.g., photon number and homodyne and heterodyne detection), the purification of noisy quantum measurements can be achieved by preamplification as suggested by Yuen [Opt. Lett. 12, 789 (1987)].

Ion exchange purification of scandium  

DOE Patents [OSTI]

An improvement in purification of scandium through ion exchange chromatography is disclosed in which the oxidation potential of the eluting solution is altered by the addition of potassium chlorate or ammonium chloride so that removal of contaminants is encouraged. The temperature, pH and concentration of the eluent HEDTA are controlled in order to maintain the scandium in the column while minimizing dilution of the scandium band. Recovery of scandium is improved by pumping dilute scandium over the column prior to stripping the scandium and precipitation. This eliminates the HEDTA ion and other monovalent cations contaminating the scandium band. This method maximizes recovery of scandium while maintaining purity. 2 figs.

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 (OSTI)

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.

Purification of aqueous cellulose ethers  

SciTech Connect (OSTI)

Manufacture of cellulose ethers usually involves high amounts of salt by-products. For application of the product, salt must be removed. In this work, we have studied the injection of high-pressure CO{sub 2} into an aqueous polymer-salt solution; we find that upon addition of isopropanol in addition to CO{sub 2}, the solution separates into two phases. One phase is rich in polymer and water, and the other phase contains mostly isopropanol, water and CO{sub 2}. The salt distributes between the two phases, thereby offering interesting possibilities for development of a new purification process for water-soluble polymers. This work presents experimental phase-equilibrium data for hydroxyethyl cellulose and sodium carboxymethyl cellulose with sodium acetate and potassium sulfate, respectively, in the region 40{degree}C and 30 to 80 bar. Based on these data, we suggest a process for the manufacture and purification of water-soluble cellulose ethers. 15 refs., 14 figs., 9 tabs.

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 (OSTI)

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.

Chapter 6 - Nanostructured Membranes for Water Purification  

Science Journals Connector (OSTI)

Application of nanotechnology to water purification is currently faced with the issue of how to design nanomaterials that are capable of collecting and preconcentrating a large number of contaminants per unit volume. Specifically, it is not clear how to interface nanoparticles with contaminants because direct addition of nanoparticles into drinking water may require extra separation steps to recover the expensive nanomaterials. Due to their large pore sizes, conventional membrane filters cannot be used for removing submicron particles, engineered nanoparticles, or biological particles within the range of 100 nm or below. To overcome these challenges, we present transformative membrane technologies that are based on the use of nanostructured conducting phase-inverted poly(amic acid) membranes to isolate and remove silver nanoparticles, quantum dots, and titanium dioxide particles in environmental samples. nPAA membranes have also been utilized to remove pathogenic bacteria in drinking water. Filtration efficiency of over 99.98% was recorded for most contaminants. The membrane pore sizes were experimentally controlled from 4 to 35 nm, and the optimized membranes were tested against three of the most common drinking water contaminants, namely Escherichia coli, Citrobacter freundii, and Staphylococcus epidermidis. Hundred percent removal of these microbial species were recorded and the results were validated with conventional plating techniques.

Membrane Purification Cell for Aluminum Recycling  

SciTech Connect (OSTI)

Recycling mixed aluminum scrap usually requires adding primary aluminum to the scrap stream as a diluent to reduce the concentration of non-aluminum constituents used in aluminum alloys. Since primary aluminum production requires approximately 10 times more energy than melting scrap, the bulk of the energy and carbon dioxide emissions for recycling are associated with using primary aluminum as a diluent. Eliminating the need for using primary aluminum as a diluent would dramatically reduce energy requirements, decrease carbon dioxide emissions, and increase scrap utilization in recycling. Electrorefining can be used to extract pure aluminum from mixed scrap. Some example applications include producing primary grade aluminum from specific scrap streams such as consumer packaging and mixed alloy saw chips, and recycling multi-alloy products such as brazing sheet. Electrorefining can also be used to extract valuable alloying elements such as Li from Al-Li mixed scrap. This project was aimed at developing an electrorefining process for purifying aluminum to reduce energy consumption and emissions by 75% compared to conventional technology. An electrolytic molten aluminum purification process, utilizing a horizontal membrane cell anode, was designed, constructed, operated and validated. The electrorefining technology could also be used to produce ultra-high purity aluminum for advanced materials applications. The technical objectives for this project were to: - Validate the membrane cell concept with a lab-scale electrorefining cell; - Determine if previously identified voltage increase issue for chloride electrolytes holds for a fluoride-based electrolyte system; - Assess the probability that voltage change issues can be solved; and - Conduct a market and economic analysis to assess commercial feasibility. The process was tested using three different binary alloy compositions (Al-2.0 wt.% Cu, Al-4.7 wt.% Si, Al-0.6 wt.% Fe) and a brazing sheet scrap composition (Al-2.8 wt.% Si-0.7 wt.% Fe-0.8 wt.% Mn),. Purification factors (defined as the initial impurity concentration divided by the final impurity concentration) of greater than 20 were achieved for silicon, iron, copper, and manganese. Cell performance was measured using its current and voltage characteristics and composition analysis of the anode, cathode, and electrolytes. The various cells were autopsied as part of the study. Three electrolyte systems tested were: LiCl-10 wt. % AlCl3, LiCl-10 wt. % AlCl3-5 wt.% AlF3 and LiF-10 wt.% AlF3. An extended four-day run with the LiCl-10 wt.% AlCl3-5 wt.% AlF3 electrolyte system was stable for the entire duration of the experiment, running at energy requirements about one third of the Hoopes and the conventional Hall-Heroult process. Three different anode membranes were investigated with respect to their purification performance and survivability: a woven graphite cloth with 0.05 cm nominal thickness & > 90 % porosity, a drilled rigid membrane with nominal porosity of 33%, and another drilled rigid graphite membrane with increased thickness. The latter rigid drilled graphite was selected as the most promising membrane design. The economic viability of the membrane cell to purify scrap is sensitive to primary & scrap aluminum prices, and the cost of electricity. In particular, it is sensitive to the differential between scrap and primary aluminum price which is highly variable and dependent on the scrap source. In order to be economically viable, any scrap post-processing technology in the U.S. market must have a total operating cost well below the scrap price differential of $0.20-$0.40 per lb to the London Metal Exchange (LME), a margin of 65%-85% of the LME price. The cost to operate the membrane cell is estimated to be < $0.24/lb of purified aluminum. The energy cost is estimated to be $0.05/lb of purified aluminum with the remaining costs being repair and maintenance, electrolyte, labor, taxes and depreciation. The bench-scale work on membrane purification cell process has demonstrated technological advantages and subs

(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

Large-scale purification of single-wall carbon nanotubes prepared by electric arc discharge  

Science Journals Connector (OSTI)

High-yield single-wall carbon nanotubes (SWNTs) have been mass-produced by dc arc discharge evaporation of a carbon electrode including 1 at.% Fe catalyst in hydrogen mixed gas [i.e., H2–inert gas (Ne, Ar, Kr, Xe), or H2–N2]. The as-grown \\{SWNTs\\} have high-crystallinity due to the high temperature of arc plasma, and the coexisting Fe catalyst nanoparticles are embedded in very thin amorphous carbon because of the in situ etching effects of hydrogen. A macroscale purification technique, which is a whole liquid-phase purification process, first reflux treatment in H2O2 solution and then rinsing with hydrochloric acid, has been developed to eliminate the coexisting Fe catalyst nanoparticles and obtain \\{SWNTs\\} with purity higher than 90 at.%.

Purification of domestic sewage by water-hyacinth (Eichhornia crassipes)  

Science Journals Connector (OSTI)

Sewage management is posing serious techno-economic problems in cities, particularly in developing countries. A new technology, sewage purification by water-hyacinth (Eichhornia crassipes), is a possible solution. This paper studied the suitability and effectiveness of water-hyacinth in treating domestic sewage. A 28-day experiment was performed under a controlled environment of a screen-house subjected to natural conditions. Several parameters were measured and analysed, including the Biochemical Oxygen Demand (BOD), Chemical Oxygen Demand (COD), faecal coliform count, nitrate and phosphate contents, pH value, heavy metals, turbidity, odour and colour at intervals of seven days. Laboratory analyses indicated that the water-hyacinth culture drastically reduced the faecal coliforms by about 80%. BOD dropped from 900 to 460 mg litre?1. COD was reduced from 1,424 to 766 mg litre?1 while the nitrogen content increased by about 77.5% and the phosphorus content rose by 63.3%. The pH value fell slightly from 8.58 to 7.81. The initial pungent odour of the raw sewage gradually disappeared during the purification period while the deep yellowish colour turned almost colourless in the final effluent sample. The sludge from the culture was rich and applicable as a bio-fertiliser. After comparison with the World Health Organisation Stream Standards, it was determined that the final effluent from water-hyacinth could be used for irrigation and fishing activities, or recycled to a flowing stream for other uses except for drinking purposes.

Oxyfuel CO2 compression: The gas phase reaction of elemental mercury and \\{NOx\\} at high pressure and absorption into nitric acid  

Science Journals Connector (OSTI)

Abstract Oxyfuel combustion is a technology which combusts coal in oxygen and recycled flue gas, producing a carbon dioxide rich flue gas for sequestration. Oxyfuel flue gas contains trace amounts of elemental mercury, which may corrode brazed aluminium heat exchangers used in the carbon dioxide purification system. International gas vendors have tested the use of the compression system to remove other flue gas impurities such as NOx; however, the reaction mechanism of mercury and its reaction products with \\{NOx\\} and nitric acid formed with condensed water vapour are unclear. This study used lab scale experiments to study the absorption of gaseous elemental mercury into nitric acid and the gas phase reaction between mercury and nitrogen dioxide formed from oxidised NO at pressures up to 25 bar. It was observed that mercury has limited absorption into nitric acid and may partially desorb out of solution after depressurisation. On the other hand, mercury reacted readily with nitrogen dioxide (formed from nitric oxide oxidation at high pressure) in the gas phase. These gas phase reactions from the oxidation of nitric oxide to nitrogen dioxide to the subsequent oxidation of elemental mercury by nitrogen dioxide were predicted using existing global kinetic equations. The limited absorption of gaseous elemental mercury in nitric acid and significant oxidation of gaseous elemental mercury by nitrogen dioxide suggests that the primary removal step for elemental mercury is through the gas phase reaction. Oxyfuel compression circuits should therefore allow sufficient residence time for this gas phase reaction to occur.

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 (OSTI)

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.

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

SciTech Connect (OSTI)

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.

Vacuum Technology  

SciTech Connect (OSTI)

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.

Initial results on lab scale hollow fiber devices indicate membrane flux ranging from 8.75 {times} 10{sup {minus}6} to 8 {times} 10{sup {minus}5} m{sup 3}/m{sup 2}/sec (2.5 to 23 scfd/ft{sub 2}) and selectivities from 150 to 300. Pilot plant experiments on propylene/propane and ethylene purge gas recovery over three to six months duration show membrane stability and product purity of 98.5% or greater using refinery grade propylene feed. Hybrid system optimization data for membranes and distillation indicate that using a side draw from the distillation tower provides advantages in terms of membrane area, purity of feed to the membrane, and low per-pass recovery coupled with high overall propylene recovery. Membrane performance data under various conditions are also presented. In addition to performance data, economic evaluation and energy savings are discussed.

Distillation sequence for the purification and recovery of hydrocarbons  

DOE Patents [OSTI]

This invention is an improved distillation sequence for the separation and purification of ethylene from a cracked gas. A hydrocarbon feed enters a C2 distributor column. The top of the C2 distributor column is thermally coupled to an ethylene distributor column, and the bottoms liquid of a C2 distributor column feeds a deethanizer column. The C2 distributor column utilizes a conventional reboiler. The top of the ethylene distributor is thermally coupled with a demethanizer column, and the bottoms liquid of the ethylene distributor feeds a C2 splitter column. The ethylene distributor column utilizes a conventional reboiler. The deethanizer and C2 splitter columns are also thermally coupled and operated at a substantially lower pressure than the C2 distributor column, the ethylene distributor column, and the demethanizer column. Alternatively, a hydrocarbon feed enters a deethanizer column. The top of the deethanizer is thermally coupled to an ethylene distributor column, and the ethylene distributor column utilizes a conventional reboiler. The top of the ethylene distributor column is thermally coupled with a demethanizer column, and the bottoms liquid of the ethylene distributor column feeds a C2 splitter column. The C2 splitter column operates at a pressure substantially lower than the ethylene distributor column, the demethanizer column, and the deethanizer column.

Membrane-based systems for carbon capture and hydrogen purification  

SciTech Connect (OSTI)

This presentation describes the activities being conducted at Los Alamos National Laboratory to develop carbon capture technologies for power systems. This work is aimed at continued development and demonstration of a membrane based pre- and post-combustion carbon capture technology and separation schemes. Our primary work entails the development and demonstration of an innovative membrane technology for pre-combustion capture of carbon dioxide that operates over a broad range of conditions relevant to the power industry while meeting the US DOE's Carbon Sequestration Program goals of 90% CO{sub 2} capture at less than a 10% increase in the cost of energy services. Separating and capturing carbon dioxide from mixed gas streams is a first and critical step in carbon sequestration. To be technically and economically viable, a successful separation method must be applicable to industrially relevant gas streams at realistic temperatures and pressures as well as be compatible with large gas volumes. Our project team is developing polymer membranes based on polybenzimidazole (PBI) chemistries that can purify hydrogen and capture CO{sub 2} at industrially relevant temperatures. Our primary objectives are to develop and demonstrate polymer-based membrane chemistries, structures, deployment platforms, and sealing technologies that achieve the critical combination of high selectivity, high permeability, chemical stability, and mechanical stability all at elevated temperatures (> 150 C) and packaged in a scalable, economically viable, high area density system amenable to incorporation into an advanced Integrated Gasification Combined-Cycle (IGCC) plant for pre-combustion CO{sub 2} capture. Stability requirements are focused on tolerance to the primary synthesis gas components and impurities at various locations in the IGCC process. Since the process stream compositions and conditions (temperature and pressure) vary throughout the IGCC process, the project is focused on the optimization of a technology that could be positioned upstream or downstream of one or more of the water-gas-shift reactors (WGSRs) or integrated with a WGSR.

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

SciTech Connect (OSTI)

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.

Extended Operations of the Pratt & Whitney Rocketdyne Pilot-Scale Compact Reformer Year 6 - Activity 3.2 - Development of a National Center for Hydrogen Technology  

SciTech Connect (OSTI)

U.S. and global demand for hydrogen is large and growing for use in the production of chemicals, materials, foods, pharmaceuticals, and fuels (including some low-carbon biofuels). Conventional hydrogen production technologies are expensive, have sizeable space requirements, and are large carbon dioxide emitters. A novel sorbent-based hydrogen production technology is being developed and advanced toward field demonstration that promises smaller size, greater efficiency, lower costs, and reduced to no net carbon dioxide emissions compared to conventional hydrogen production technology. Development efforts at the pilot scale have addressed materials compatibility, hot-gas filtration, and high-temperature solids transport and metering, among other issues, and have provided the basis for a preliminary process design with associated economics. The process was able to achieve a 93% hydrogen purity on a purge gasfree basis directly out of the pilot unit prior to downstream purification.

Catalytically upgraded landfill gas as a cost-effective alternative for fuel cells  

Science Journals Connector (OSTI)

The potential use of landfill gas as feeding fuel for the so-called molten carbonate fuel cells (MCFC) imposes the need for new upgrading technologies in order to meet the much tougher feed gas specifications of this type of fuel cells in comparison to gas engines. Nevertheless, MCFC has slightly lower purity demands than low temperature fuel cells. This paper outlines the idea of a new catalytic purification process for landfill gas conditioning, which may be supposed to be more competitive than state-of-the-art technologies and summarises some lab-scale results. This catalytic process transforms harmful landfill gas minor compounds into products that can be easily removed from the gas stream by a subsequent adsorption step. The optimal process temperature was found to be in the range 250–400 °C. After a catalyst screening, two materials were identified, which have the ability to remove all harmful minor compounds from landfill gas. The first material was a commercial alumina that showed a high activity towards the removal of organic silicon compounds. The alumina protects both a subsequent catalyst for the removal of other organic minor compounds and the fuel cell. Due to gradual deactivation caused by silica deposition, the activated alumina needs to be periodically replaced. The second material was a commercial V2O5/TiO2-based catalyst that exhibited a high activity for the total oxidation of a broad spectrum of other harmful organic minor compounds into a simpler compound class “acid gases (HCl, HF and SO2)”, which can be easily removed by absorption with, e.g. alkalised alumina. The encouraging results obtained allow the scale-up of this LFG conditioning process to test it under real LFG conditions.

Potential of carbon nanotubes in water purification: an approach towards the development of an integrated membrane system  

Science Journals Connector (OSTI)

The problems of water shortages and lack of access to safe drinking water have been and will continue to grow as major global problems. To alleviate these problems, water purification technologies are being updated. Recent years have witnessed impressive breakthroughs towards practical application of nanostructured materials such as Carbon Nanotubes (CNTs) in the field of water purification owing to their unique thermal, electrical and mechanical properties. These nanoscale structures need to be arranged into well-defined configurations in order to build integrated systems with high efficiency (the nanotubes being reusable, whereas the traditional membranes foul easily and require frequent replacements), high flux (owing to the hydrophobic super smooth inner surface of nanotubes), and with improvements in chemical selectivity (through suitable chemical functionalisation of the CNTs), so that the idea of using CNTs in separation technology can be made realistic and the potential benefits of practical application of these unique materials can be exploited. This paper assesses the CNTs as an emerging technology in water purification system, particularly with respect to its potential for the removal of arsenic, fluoride, heavy metals and toxic organic components.

Water Purification by Using Microplasma Treatment  

Science Journals Connector (OSTI)

Dielectric barrier discharge microplasma generated at the surface of water is proposed as a solution for water treatment. It is an economical and an ecological technology for water treatment due to its generation at atmospheric pressure and low discharge voltage. Microplasma electrodes were placed at small distance above the water thus active species and radicals were flown by the gas towards the water surface and furthermore reacted with the target to be decomposed. Indigo carmine was chosen as the target to be decomposed by the effect of active species and radicals generated between the electrodes. Air, oxygen, nitrogen and argon were used as discharge gases. Measurement of absorbance showed the decomposition of indigo carmine by microplasma treatment. Active species and radicals of oxygen origin so called ROS (reactive oxidative species) were considered to be the main factor in indigo carmine decomposition. The decomposition rate increased with the increase of the treatment time as shown by the spectrophotometer analysis. Discharge voltage also influenced the decomposition process.

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 (OSTI)

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.

Chapter 3 - Principles of Water Purification  

Science Journals Connector (OSTI)

Abstract This chapter describes the principles of water purification. An important point to observe is the difference between purifying drinking water and purifying water optimal for life of organisms. In the former case, it is important that organisms, prokaryotes and protists, are effectively killed in the water treatment. In the latter instance, the purified water must allow all organisms to live. Chlorination and other treatments that are used to purify drinking water are toxic to all organisms. Water treatment first mechanically removes large objects, whereafter much of the organic material is biodegraded via digestion by anaerobic and aerobic bacteria. When wastes are biodegraded, production of biogas and heat occurs. A final step in wastewater treatment involves the removal of certain compounds, such as phosphorus by precipitation as, for example, insoluble iron phosphate, and of some metals by hyperaccumulating plants.

By staging the combustion, the temperature and heat transfer can be controlled. The potential benefits of the process are: higher efficiency, reduced process gas volume, increased radiative heat transfer, reduced oxygen demands, reduced capital equipment costs, increased CO2 purity entering the carbon compression and purification unit, and reduced auxiliary power demands. These benefits are expected to yield a lower cost of electricity than alternative approaches to pressurized oxy-combustion.

R&D priorities in the field of sustainable remediation and purification of agro-industrial and municipal wastewater  

Science Journals Connector (OSTI)

Abstract This article was presented as a position paper during the Environmental Biotechnology and Microbiology Conference in Bologna, Italy in April 2012. It indicates major and emerging environmental biotechnology research and development (R&D) priorities for EU members in the field of sustainable remediation and purification of agro-industrial and municipal wastewater. The identified priorities are: anaerobic/aerobic microbial treatment, combination of photochemical and biological treatment, phytoremediation and algae-based remediation, as well as innovative technologies currently investigated, such as enzyme-based treatment, bioelectrochemical treatment and recovery of nutrients and reuse of cleaned water. State of the art, research needs and prospective development in these domains are crucially discussed. As a result, goals of the future development of bioremediation and purification processes are defined and the way to achieve them is proposed.

Separation of flue-gas scrubber sludge into marketable products. Second year, second quarterly technical progress report, Quarter No. 6, December 1, 1994--February 28, 1995  

SciTech Connect (OSTI)

To reduce their sulfur emissions, many coal-fired electric power plants use wet flue-gas scrubbers. These scrubbers convert sulfur oxides into solid sulfate and sulfite sludge, which must then be disposed of. This sludge is a result of reacting limestone with sulfur dioxide to precipitate calcium sulfite and calcium sulfate. It consists of calcium sulfite (CaSO{sub 3}{sm_bullet}0.5H{sub 2}O), gypsum (CaSO{sub 4}{sm_bullet}2H{sub 2}O), and unreacted limestone (CaCO{sub 3}) or lime (Ca(OH){sub 2}), with miscellaneous objectionable impurities such as iron oxides, silica, and magnesium, sodium, and potassium oxides or salts. These impurities prevent many sludges from being utilized as a replacement for natural gypsum, and as a result they must be disposed of in landfills, which presents a serious disposal problem. This project is studying the characteristics of flue-gas scrubber sludges from several sources, which is necessary for the development of purification technologies which will make it possible to directly utilize scrubber sludges rather than landfilling them. This purification will consist of minimal-reagent froth flotation, using the surface properties of the particles of unreacted limestone to remove them and their associated impurities from the material, leaving a purified calcium sulfite/gypsum product.

Forward osmosis :a new approach to water purification and desalination.  

SciTech Connect (OSTI)

Fresh, potable water is an essential human need and thus looming water shortages threaten the world's peace and prosperity. Waste water, brackish water, and seawater have great potential to fill the coming requirements. Unfortunately, the ability to exploit these resources is currently limited in many parts of the world by both the cost of the energy and the investment in equipment required for purification/desalination. Forward (or direct) osmosis is an emerging process for dewatering aqueous streams that might one day help resolve this problem. In FO, water from one solution selectively passes through a membrane to a second solution based solely on the difference in the chemical potential (concentration) of the two solutions. The process is spontaneous, and can be accomplished with very little energy expenditure. Thus, FO can be used, in effect, to exchange one solute for a different solute, specifically chosen for its chemical or physical properties. For desalination applications, the salts in the feed stream could be exchanged for an osmotic agent specifically chosen for its ease of removal, e.g. by precipitation. This report summarizes work performed at Sandia National Laboratories in the area of FO and reviews the status of the technology for desalination applications. At its current state of development, FO will not replace reverse osmosis (RO) as the most favored desalination technology, particularly for routine waters. However, a future role for FO is not out of the question. The ability to treat waters with high solids content or fouling potential is particularly attractive. Although our analysis indicates that FO is not cost effective as a pretreatment for conventional BWRO, water scarcity will likely drive societies to recover potable water from increasingly marginal resources, for example gray water and then sewage. In this context, FO may be an attractive pretreatment alternative. To move the technology forward, continued improvement and optimization of membranes is recommended. The identification of optimal osmotic agents for different applications is also suggested as it is clear that the space of potential agents and recovery processes has not been fully explored.

High performance and antifouling vertically aligned carbon nanotube membrane for water purification  

Science Journals Connector (OSTI)

Abstract A vertically aligned carbon nanotube (VA CNT) membrane created from the successful fusion of nanotechnology and membrane technology has been stated to be a next generation membrane due to its fast water transport and antimicrobial properties. Although previous studies of the VA CNT membrane reported the potential for fast water transport or desalination by molecular dynamics simulation, this study is the first to report on the feasibility of using the VA CNT membrane for water purification. The VA CNT membrane (4.8 nm of pore diameter and 6.8×1010 #/cm2 of pore density) was fabricated and its flux, rejection performance, and membrane biofouling tendency were evaluated in comparison to the commercial ultrafiltration (UF) membrane. The VA CNT membrane appeared to have a water flux approximately three times higher than the UF membrane and water transport approximately 70,000 times faster than conventional no-slip flow. This higher flux was peculiarly observed in water, the most hydrophilic solvent, while other solvents showed that permeate flux decreased with higher viscosity. The rejection property of the VA CNT membrane as examined by the MWCO measurement was similar to the commercial UF membrane. Additionally, the VA CNT membrane showed better biofouling resistance with approximately 15% less permeate flux reduction and 2 log less bacterial attachment than the UF membrane. This study reports the high potential of the VA CNT membrane with antifouling property in the water purification process.

On a cryogenic noble gas ion catcher  

E-Print Network [OSTI]

In-situ purification of the gas used as stopping medium in a noble gas ion catcher by operating the device at low temperatures of 60 to 150 K was investigated. Alpha-decay recoil ions from a 223Ra source served as energetic probes. The combined ion survival and transport efficiencies for 219Rn ions saturated below about 90 K, reaching 28.7(17) % in helium, 22.1(13) % in neon, and 17.0(10) % in argon. These values may well reflect the charge exchange and stripping cross sections during the slowing down of the ions, and thus represent a fundamental upper limit for the efficiency of noble gas ion catcher devices. We suggest the cryogenic noble gas ion catcher as a technically simpler alternative to the ultra-high purity noble gas ion catcher operating at room temperature.

A combined purification of fluorine-containing foul water  

SciTech Connect (OSTI)

An experiment was carried out for two-stage water purification. A solution of AOC ( aluminum oxychloride) was added to a neutralized and clarified foul water and the pH brought up to 11.5 by lime water. After cleaning, the required components were identified. This method is simple and in relation to the apparatus used does not differ from the neutralization method. Therefore under industrial conditions the process can be carried out using the standard equipment. The hypothesis that flouride is codeposited with CHSA-3 has been confirmed experimentally. With additional purification using the sulfo-aluminate method, the value of the pH immediately after deposition is greater than the norm. The results obtained have made it possible to develop a simple, effective method of combining high purification of foul water from flourine and sulfates with the simultaneous additional deposition of heavy ferrous metals.

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 (OSTI)

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.

Novel membrane technology for green ethylene production.  

SciTech Connect (OSTI)

Ethylene is currently produced by pyrolysis of ethane in the presence of steam. This reaction requires substantial energy input, and the equilibrium conversion is thermodynamically limited. The reaction also produces significant amounts of greenhouse gases (CO and CO{sub 2}) because of the direct contact between carbon and steam. Argonne has demonstrated a new way to make ethylene via ethane dehydrogenation using a dense hydrogen transport membrane (HTM) to drive the unfavorable equilibrium conversion. Preliminary experiments show that the new approach can produce ethylene yields well above existing pyrolysis technology and also significantly above the thermodynamic equilibrium limit, while completely eliminating the production of greenhouse gases. With Argonne's approach, a disk-type dense ceramic/metal composite (cermet) membrane is used to produce ethylene by dehydrogenation of ethane at 850 C. The gas-transport membrane reactor combines a reversible chemical reaction with selective separation of one product species and leads to increased reactant conversion to the desired product. In an experiment ethane was passed over one side of the HTM membrane and air over the other side. The hydrogen produced by the dehydrogenation of ethane was removed and transported through the HTM to the air side. The air provided the driving force required for the transport of hydrogen through the HTM. The reaction between transported hydrogen and oxygen in air can provide the energy needed for the dehydrogenation reaction. At 850 C and 1-atm pressure, equilibrium conversion of ethane normally limits the ethylene yield to 64%, but Argonne has shown that an ethylene yield of 69% with a selectivity of 88% can be obtained under the same conditions. Coking was not a problem in runs extending over several weeks. Further improved HTM materials will lower the temperature required for high conversion at a reasonable residence time, while the lower temperature will suppress unwanted side reactions and prolong membrane life. With the Argonne approach, oxygen does not contact the ethane/ethylene stream, so oxidation products are not formed. Consequently, higher selectivity to ethylene and fewer by-products can be achieved. Some benefits are: (1) Simplifies overall product purification and processing schemes; (2) Results in greater energy efficiency; (3) Completely eliminates greenhouse gases from the reactor section; and (4) Lowers the cost of the 'back end' purification train, which accounts for about 70% of the capital cost of a conventional ethylene production unit.
