High pressure conversion of \\{NOx\\} and Hg and their capture as aqueous condensates in a laboratory piston-compressor simulating oxy-fuel CO2 compression  

Science Journals Connector (OSTI)

Abstract Oxy-fuel technology for CO2 capture has largely focused on combustion characteristics as a driver towards demonstration. Impurity removal studies typically centre on the how current environmental control units (FGD, SCR, activated carbon beds) operate in oxy-fuel firing. However, it is expected that some removal of \\{NOx\\} and \\{SOx\\} may occur during compression of flue gas through the lead chamber process. Some commercial systems link the capture of mercury to the formation of acid condensates (as a soluble mercury salt). Mercury in compressed flue gas represents a potential corrosion risk in the processing of CO2 from oxy-fuel combustion processes. Gas phase elemental mercury (Hg0) is difficult to remove from the flue gas and the level of cleaning required to prevent corrosion of cryogenic brazed aluminium heat exchangers is uncertain. This work has investigated the behaviour of gaseous Hg0 in pressurised oxy-fuel systems in terms of the potential capture in acidic condensates, interaction with \\{NOx\\} gases and liquid stability on de-pressurisation. The work was undertaken on an adapted laboratory scale three stage axial-piston compressor with gas and liquid sampling at pressures up to 30 bar. The main finding was that gaseous Hg0 reacts readily with NO2 formed from NO oxidation at high pressure. This reaction occurred without the presence of water, either water vapour or liquid water, contrary to speculation in the literature. Without NO2, no capture of Hg0 was observed in the compression system. Overall, the capture of mercury during compression occurred as a consequence of high pressure, longer residence time and concentration of NO2. Capture rates of 100% Hg and 75–83% \\{NOx\\} were measured from the compressor exit at 30 bar g.

Flue Gas Perification Utilizing SOx/NOx Reactions During Compression of CO2 Derived from Oxyfuel Combustion  

SciTech Connect

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 CO2 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 CO2 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.

Analysis of different control strategies for the simultaneous reduction of CO2 and NOx emissions of a diesel hybrid passenger car  

Science Journals Connector (OSTI)

Different control strategies for a diesel parallel hybrid passenger car were evaluated through numerical simulations. Two different control strategies were analysed: the first focused on fuel consumption minimisation, the second on NOx emissions cuts. Each of these goals was addressed through two different methodologies, the first based on a group of heuristic laws, the second focused on the instantaneous minimisation of a cost function that takes into account both the fuel and battery energies. A first assessment of the potential of a diesel hybrid passenger car as far as fuel consumption and NOx emissions reductions are concerned was obtained.

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.

CO2 interaction with geomaterials.  

SciTech Connect

This work compares the sorption and swelling processes associated with CO2-coal and CO2-clay interactions. We investigated the mechanisms of interaction related to CO2 adsortion in micropores, intercalation into sub-micropores, dissolution in solid matrix, the role of water, and the associated changes in reservoir permeability, for applications in CO2 sequestration and enhanced coal bed methane recovery. The structural changes caused by CO2 have been investigated. A high-pressure micro-dilatometer was equipped to investigate the effect of CO2 pressure on the thermoplastic properties of coal. Using an identical dilatometer, Rashid Khan (1985) performed experiments with CO2 that revealed a dramatic reduction in the softening temperature of coal when exposed to high-pressure CO2. A set of experiments was designed for -20+45-mesh samples of Argonne Premium Pocahontas No.3 coal, which is similar in proximate and ultimate analysis to the Lower Kittanning seam coal that Khan used in his experiments. No dramatic decrease in coal softening temperature has been observed in high-pressure CO2 that would corroborate the prior work of Khan. Thus, conventional polymer (or 'geopolymer') theories may not be directly applicable to CO2 interaction with coals. Clays are similar to coals in that they represent abundant geomaterials with well-developed microporous structure. We evaluated the CO2 sequestration potential of clays relative to coals and investigated the factors that affect the sorption capacity, rates, and permanence of CO2 trapping. For the geomaterials comparison studies, we used source clay samples from The Clay Minerals Society. Preliminary results showed that expandable clays have CO2 sorption capacities comparable to those of coal. We analyzed sorption isotherms, XRD, DRIFTS (infrared reflectance spectra at non-ambient conditions), and TGA-MS (thermal gravimetric analysis) data to compare the effects of various factors on CO2 trapping. In montmorillonite, CO2 molecules may remain trapped for several months following several hours of exposure to high pressure (supercritical conditions), high temperature (above boiling point of water) or both. Such trapping is well preserved in either inert gas or the ambient environment and appears to eventually result in carbonate formation. We performed computer simulations of CO2 interaction with free cations (normal modes of CO2 and Na+CO2 were calculated using B3LYP / aug-cc-pVDZ and MP2 / aug-cc-pVDZ methods) and with clay structures containing interlayer cations (MD simulations with Clayff potentials for clay and a modified CO2 potential). Additionally, interaction of CO2 with hydrated Na-montmorillonite was studied using density functional theory with dispersion corrections. The sorption energies and the swelling behavior were investigated. Preliminary modeling results and experimental observations indicate that the presence of water molecules in the interlayer region is necessary for intercalation of CO2. Our preliminary conclusion is that CO2 molecules may intercalate into interlayer region of swelling clay and stay there via coordination to the interlayer cations.

CO2 maritime transportation  

Science Journals Connector (OSTI)

The objective of this study is to describe the complete transport chain of CO2 between capture and storage including a ship transport. This last one is composed by the following steps: Shore terminal including the liquefaction, temporary storage and CO2 loading. Ship with a capacity of 30,000 m3. On or off shore terminal including an unloading system, temporary storage and export towards the final storage. Between all the possible thermodynamic states, the liquid one is most relevant two options are compared in the study (?50 °C, 7 bar) and (?30 °C, 15 bar). The ship has an autonomy of 6 days, is able to cover 1000 km with a cargo of 2.5 Mt/year. Several scenarios are studied varying the geographical position of the CO2 source, the number of harbours and the way the CO2 is finally stored. Depending on the option, the transport cost varies from 24 to 32 €/tCO2. This study confirms the conclusion of a previous study supported by ADEME, the cost transport is not negligible regarding the capture one when ships are considered. Transport by ship becomes a more economical option compared with an off shore pipeline when the distance exceeds 350 km and with an onshore pipeline when it exceeds 1100 km.

Hybrid Membrane/Absorption Process for Post-Combustion CO2 Capture Hybrid Membrane/Absorption Process for Post-Combustion CO2 Capture Project No.: DE-FE0004787 Gas Technology Institute is partnering with PoroGen Corporation and Aker Process Systems in a three-year effort to develop a hybrid technology for CO2 capture from flue gases based on a combination of solvent absorption and hollow fiber membrane technologies. The technology could also apply to removal of numerous other gas pollutants such as NOx and SOx, separation of CO2 from hydrogen in refinery streams, and separation of CO2 from natural gas (natural gas sweetening). The technology increases interfacial gas/liquid area by a factor of ten over conventional packed or tray columns, thus increasing mass transfer. The selectivity is controlled by the chemical affinity of CO2 with a hindered amine. The process results in lower steam regeneration energy, and the CO2 is generated at pressure, reducing compression costs. The project includes bench-scale testing on a 25 kWe-equivalent slipstream at Midwest Generation's Joliet Power Station.

Novel Co Novel Co 2 - PhiliC AbsorbeNts Summary The ability to separate a high pressure mixture of CO 2 and H 2 such that a high pressure stream of CO 2 for sequestration and a high pressure stream of H 2 for energy are produced remains an elusive goal. This research has identified a class of compounds that melt in the presence of high pressure CO 2 , forming a liquid phase composed of roughly 50wt% CO 2 and 50wt% of the compound. Unlike conventional solvents that require substantial depressurization during regeneration to release a low pressure CO 2 stream, these novel compounds completely release the CO 2 at many hundreds of psia as the compound solidifies. This work will reveal whether one of more of these compounds can selectively remove CO 2 from a mixture

Given the public’s interest and concern over the impact of atmospheric greenhouse gases (GHGs) on global warming and related climate change patterns, the course is a timely discussion of the underlying geochemical and mineralogical processes associated with gas-water-mineral-interactions encountered during geological sequestration of CO2. The geochemical and mineralogical processes encountered in the subsurface during storage of CO2 will play an important role in facilitating the isolation of anthropogenic CO2 in the subsurface for thousands of years, thus moderating rapid increases in concentrations of atmospheric CO2 and mitigating global warming. Successful implementation of a variety of geological sequestration scenarios will be dependent on our ability to accurately predict, monitor and verify the behavior of CO2 in the subsurface. The course was proposed to and accepted by the Mineralogical Society of America (MSA) and The Geochemical Society (GS).

Update on CO2 emissions  

SciTech Connect

Emissions of CO2 are the main contributor to anthropogenic climate change. Here we present updated information on their present and near-future estimates. We calculate that global CO2 emissions from fossil fuel burning decreased by 1.3% in 2009 owing to the global financial and economic crisis that started in 2008; this is half the decrease anticipated a year ago1. If economic growth proceeds as expected2, emissions are projected to increase by more than 3% in 2010, approaching the high emissions growth rates that were observed from 2000 to 20081, 3, 4. We estimate that recent CO2 emissions from deforestation and other land-use changes (LUCs) have declined compared with the 1990s, primarily because of reduced rates of deforestation in the tropics5 and a smaller contribution owing to forest regrowth elsewhere.

Hybrid heat exchange for the compression capture of CO2 from recirculated flue gas  

SciTech Connect

An approach proposed for removal of CO2 from flue gas cools and compresses a portion of a recirculated flue-gas stream, condensing its volatile materials for capture. Recirculating the flue gas concentrates SOx, H2O and CO2 while dramatically reducing N2 and NOx, enabling this approach, which uses readily available industrial components. A hybrid system of indirect and direct-contact heat exchange performs heat and mass transfer for pollutant removal and energy recovery. Computer modeling and experimentation combine to investigate the thermodynamics, heat and mass transfer, chemistry and engineering design of this integrated pollutant removal (IPR) system.

NETL: CO2 Emissions Control  

NLE Websites -- All DOE Office Websites (Extended Search)

Systems Analysis Systems Analysis DOE/NETL possesses strong systems analysis and policy-support capabilities. Systems analysis in support of the Innovations for Existing Plants Program consists of conducting various energy analyses that provide input to decisions on issues such as national plans and programs, resource use, environmental and energy security policies, technology options for research and development programs, and paths to deployment of energy technology. This work includes technology, benefits, and current situation and trends analyses related to CO2 emissions control. Systems analyses and economic modeling of potential new processes are crucial to providing sound guidance to R&D efforts. Since the majority of new CO2 capture technologies are still at a bench scale level of development, a conceptual design is first generated with emphasis on mass and energy balances. Based on available data and/or engineering estimates, these systems are optimized, and "what-if" scenarios are evaluated to identify barriers to deployment and help the process developers establish system performance targets. Reports that have been generated describing systems analyses in support of carbon capture efforts are shown in the table below.

CO2 laser frequency multiplication  

SciTech Connect

The duration of the mode-locked CO(2) laser pulses was measured to be 0.9 + or - nsec by the technique of (second harmonic) autocorrelation. Knowing the pulse duration, the spot size, and the harmonic conversion efficiency, a detailed fit of experiment to theory gave an estimate of the nonlinear coefficient of AgGaSe(2). d36 = 31 + or - V(1), in agreement with the most accurate literature values. A number of experiments were made with longer pulse trains in which the highest harmonic energy conversion reached 78%. The damage threshold was measured and it turned out to be related much more strongly to fluence than intensity. The shorter pulse trains had peak intensities of close to 300 MW 1/cm squared whereas the longer trains (3 usec) had intensities up to 40 MW 1/cm squared.

Emissions from Multi-Burners Emissions from Multi-Burners The University of Utah working with Reaction Engineering International and Brigham Young University is investigating a project that consists of integrated experimental, theoretical and computational modeling efforts. The primary objective is to evaluate NOx formation/destruction processes as they occur in multi-burner arrays, a geometry almost always utilized in utility practice. Most controlled experimental work examining NOx has been conducted on single burners. The range of potential intra-burner interactions are likely to provide added degrees of freedom for reducing NOx. The resultant findings may allow existing utilities to arrange fuel and air distribution to minimize NOx. In new applications, orientation of individual burners within an array may also be altered to reduce NOx. Comprehensive combustion codes will be modified to incorporate the latest submodels of nitrogen release and heterogeneous chemistry. Comparison of pilot scale experiments and simulations will be utilized to validate/develop theory.

Model for NOx Emissions in Biomass Cofiring Model for NOx Emissions in Biomass Cofiring Southern Research Institute is developing a validated tool or methodology to accurately and confidently design and optimize biomass-cofiring systems for full-scale utility boilers to produce the lowest NOX emissions and the least unburned carbon. The computer model will be validated through an extensive set of tests at the 6 MMBtu/hr pilot combustor in the Southern Company/Southern Research Institute Combustion Research Facility. Full-scale demonstration testing can be compared to the model for further validation. The project is designed to balance the development of a systematic and expansive database detailing the effects of cofiring parameters on NOx formation with the complementary modeling effort that will yield a capability to predict, and therefore optimize, NOx reductions by the selection of those parameters. The database of biomass cofiring results will be developed through an extensive set of pilot-scale tests at the Southern Company/Southern Research Institute Combustion Research Facility. The testing in this program will monitor NOx, LOI, and other emissions over a broad domain of biomass composition, coal quality, and cofiring injection configurations to quantify the dependence of NOx formation and LOI on these parameters. This database of cofiring cases will characterize an extensive suite of emissions and combustion properties for each of the fuel and injection configuration combinations tested.

CO2 Sequestration in Basalt Formations  

NLE Websites -- All DOE Office Websites (Extended Search)

CO CO 2 SequeStratiOn in BaSalt FOrmatiOnS Background There is growing concern that buildup of greenhouse gases, especially carbon dioxide (CO 2 ), in the atmosphere is contributing to global climate change. One option for mitigating this effect is to sequester CO 2 in geologic formations. Numerous site assessments for geologic sequestration of CO 2 have been conducted in virtually every region of the United States. For the most part, these studies have involved storing CO 2 in saline formation, deep coal seams, and depleted oil and gas reservoirs. Another option, however, is basalt formations. Basalt is a dark-colored, silica-rich, volcanic rock that contains cations-such as calcium, magnesium, and iron-that can combine with CO 2 to form carbonate minerals. Basalt formations have not received much

Experimental investigation of the thermal and diluent effects of EGR components on combustion and \\{NOx\\} emissions of a turbocharged natural gas SI engine  

Science Journals Connector (OSTI)

Abstract Exhaust gas recirculation (EGR) is one of effective measures used in natural gas (NG) engines to reduce nitrogen oxides (NOx) emissions. Each component of EGR gases can exert different effects on NG combustion and \\{NOx\\} formation rates, such as thermal effect, diluent effect, and chemical effect. In this study, the thermal and diluent effects of the main components of EGR gases, including carbon dioxide (CO2) and nitrogen (N2), were experimentally investigated. The experiments were arranged based on an electronically controlled heavy-duty natural gas spark-ignition (SI) engine with multi-point injection and 6-cylinder. In order to define the diluent effect of EGR components, argon (Ar) was introduced to the test, for its low and unchangeable specific heat capacity under different temperatures. The results showed that the contribution of the diluent effect on \\{NOx\\} reductions was 50–60% and 41–53% for N2 and CO2 respectively, and the relevant contribution of the thermal effect was 40–50% and 47–59% respectively. CO2 had greater effects on NG combustion and \\{NOx\\} formation rates than N2 at the same dilution ratio. Increasing Ar improved the thermal efficiency due to the higher specific heat ratio provided. Meanwhile, \\{NOx\\} emissions were found to be decreased with increasing DR as a result of the diluent effect of Ar on combustion and \\{NOx\\} formations.

Europe Europe » Poland Poland Fossil-Fuel CO2 Emissions Graph graphic Graphics Data graphic Data Trends Carbon dioxide emissions from Poland's use of fossil-fuels and cement production climbed at a remarkably steady rate of 3.9% per year from 1800 until 1980, when they dropped abruptly (11.7%). Fossil-fuel CO2 emissions crept back up throughout the 1980s peaking in 1987 at 127 million metric tons of carbon. Since the 1987 high, CO2 emissions have plummeted 32% to early 1970s levels while per capita emissions have dropped to late 1960s levels. Poland is the world's ninth largest producer of coal and emissions are predominantly from coal burning: 97% in 1950 and 68% in 2008. The drop following 1980 is apparent in rates of liquid fuel burning but releases from consumption of petroleum products have returned and surpassed 1980s

10 MW Supercritical CO2 Turbine Test  

SciTech Connect

The Supercritical CO2 Turbine Test project was to demonstrate the inherent efficiencies of a supercritical carbon dioxide (s-CO2) power turbine and associated turbomachinery under conditions and at a scale relevant to commercial concentrating solar power (CSP) projects, thereby accelerating the commercial deployment of this new power generation technology. The project involved eight partnering organizations: NREL, Sandia National Laboratories, Echogen Power Systems, Abengoa Solar, University of Wisconsin at Madison, Electric Power Research Institute, Barber-Nichols, and the CSP Program of the U.S. Department of Energy. The multi-year project planned to design, fabricate, and validate an s-CO2 power turbine of nominally 10 MWe that is capable of operation at up to 700°C and operates in a dry-cooled test loop. The project plan consisted of three phases: (1) system design and modeling, (2) fabrication, and (3) testing. The major accomplishments of Phase 1 included: Design of a multistage, axial-flow, s-CO2 power turbine; Design modifications to an existing turbocompressor to provide s-CO2 flow for the test system; Updated equipment and installation costs for the turbomachinery and associated support infrastructure; Development of simulation tools for the test loop itself and for more efficient cycle designs that are of greater commercial interest; Simulation of s-CO2 power cycle integration into molten-nitrate-salt CSP systems indicating a cost benefit of up to 8% in levelized cost of energy; Identification of recuperator cost as a key economic parameter; Corrosion data for multiple alloys at temperatures up to 650ºC in high-pressure CO2 and recommendations for materials-of-construction; and Revised test plan and preliminary operating conditions based on the ongoing tests of related equipment. Phase 1 established that the cost of the facility needed to test the power turbine at its full power and temperature would exceed the planned funding for Phases 2 and 3. Late in Phase 1 an opportunity arose to collaborate with another turbine-development team to construct a shared s-CO2 test facility. The synergy of the combined effort would result in greater facility capabilities than either separate project could produce and would allow for testing of both turbine designs within the combined budgets of the two projects. The project team requested a no-cost extension to Phase 1 to modify the subsequent work based on this collaborative approach. DOE authorized a brief extension, but ultimately opted not to pursue the collaborative facility and terminated the project.

NETL: Carbon Storage - CO2 Utilization Focus Area  

NLE Websites -- All DOE Office Websites (Extended Search)

CO2 Utilization CO2 Utilization Carbon Storage CO2 Utilization Focus Area Carbon dioxide (CO2) utilization efforts focus on pathways and novel approaches for reducing CO2 emissions by developing beneficial uses for the CO2 that will mitigate CO2 emissions in areas where geologic storage may not be an optimal solution. CO2 can be used in applications that could generate significant benefits. It is possible to develop alternatives that can use captured CO2 or convert it to useful products such chemicals, cements, or plastics. Revenue generated from the utilized CO2 could also offset a portion of the CO2 capture cost. Processes or concepts must take into account the life cycle of the process to ensure that additional CO2 is not produced beyond what is already being removed from or going into the atmosphere. Furthermore, while the utilization of CO2 has some potential to reduce greenhouse gas emissions to the atmosphere, CO2 has certain disadvantages as a chemical reactant. Carbon dioxide is rather inert and non-reactive. This inertness is the reason why CO2 has broad industrial and technical applications. Each potential use of CO2 has an energy requirement that needs to be determined; and the CO2 produced to create the energy for the specific utilization process must not exceed the CO2 utilized.

Commitment accounting of CO2 emissions  

Science Journals Connector (OSTI)

The world not only continues to build new coal-fired power plants, but built more new coal plants in the past decade than in any previous decade. Worldwide, an average of 89 gigawatts per year (GW yr–1) of new coal generating capacity was added between 2010 and 2012, 23 GW yr–1 more than in the 2000–2009 time period and 56 GW yr–1 more than in the 1990–1999 time period. Natural gas plants show a similar pattern. Assuming these plants operate for 40 years, the fossil-fuel burning plants built in 2012 will emit approximately 19 billion tons of CO2 (Gt CO2) over their lifetimes, versus 14 Gt CO2 actually emitted by all operating fossil fuel power plants in 2012. We find that total committed emissions related to the power sector are growing at a rate of about 4% per year, and reached 307 (with an estimated uncertainty of 192–439) Gt CO2 in 2012. These facts are not well known in the energy policy community, where annual emissions receive far more attention than future emissions related to new capital investments. This paper demonstrates the potential for 'commitment accounting' to inform public policy by quantifying future emissions implied by current investments.

Northern California CO2 Reduction Project  

SciTech Connect

C6 Resources LLC, a wholly owned subsidiary of Shell Oil Company, worked with the US Department of Energy (DOE) under a Cooperative Agreement to develop the Northern California CO2 Reduction Project. The objective of the Project is to demonstrate the viability of using Carbon Capture and Sequestration (CCS) to reduce existing greenhouse gas emissions from industrial sources on a large-scale. The Project will capture more than 700,000 metric tonnes of CO2 per year, which is currently being vented to the atmosphere from the Shell Martinez Refinery in Contra Costa County. The CO2 will be compressed and dehydrated at the refinery and then transported via pipeline to a sequestration site in a rural area in neighboring Solano County. The CO2 will be sequestered into a deep saline formation (more than two miles underground) and will be monitored to assure secure, long-term containment. The pipeline will be designed to carry as much as 1,400,000 metric tonnes of CO2 per year, so additional capacity will be available to accommodate CO2 captured from other industrial sources. The Project is expected to begin operation in 2015. The Project has two distinct phases. The overall objective of Phase 1 was to develop a fully definitive design basis for the Project. The Cooperative Agreement with the DOE provided cost sharing for Phase 1 and the opportunity to apply for additional DOE cost sharing for Phase 2, comprising the design, construction and operation of the Project. Phase 1 has been completed. DOE co-funding is provided by the American Recovery and Reinvestment Act (ARRA) of 2009. As prescribed by ARRA, the Project will stimulate the local economy by creating manufacturing, transportation, construction, operations, and management jobs while addressing the need to reduce greenhouse gas emissions at an accelerated pace. The Project, which will also assist in meeting the CO2 reduction requirements set forth in California?s Climate Change law, presents a major opportunity for both the environment as well as the region. C6 Resources is conducting the Project in collaboration with federally-funded research centers, such as Lawrence Berkeley National Lab and Lawrence Livermore National Lab. C6 Resources and Shell have identified CCS as one of the critical pathways toward a worldwide goal of providing cleaner energy. C6 Resources, in conjunction with the West Coast Regional Carbon Sequestration Partnership (WESTCARB), has conducted an extensive and ongoing public outreach and CCS education program for local, regional and state-wide stakeholders. As part of a long term relationship, C6 Resources will continue to engage directly with community leaders and residents to ensure public input and transparency. This topical report summarizes the technical work from Phase 1 of the Project in the following areas: ? Surface Facility Preliminary Engineering: summarizes the preliminary engineering work performed for CO2 capture, CO2 compression and dehydration at the refinery, and surface facilities at the sequestration site ? Pipeline Preliminary Engineering: summarizes the pipeline routing study and preliminary engineering design ?

Synthesis, characterization and performance of single-component CO2-binding organic liquids (CO2BOL) for post combustion CO2 capture  

SciTech Connect

Carbon dioxide (CO2) emission to the atmosphere will increase significantly with the shift to coal powered plants for energy generation. This increase in CO2 emission will contribute to climate change. There is need to capture and sequester large amounts of CO2 emitted from these coal power plants in order to mitigate the environmental effects. Here we report the synthesis, characterization and system performance of multiple third generation CO2 binding organic liquids (CO2BOLs) as a solvent system for post combustion gas capture. Alkanolguanidines and alkanolamidines are single component CO2BOLs that reversibly bind CO2 chemically as liquid zwitterionic amidinium / guanidinium alkylcarbonates. Three different alkanolguanidines and alkanolamidines were synthesized and studied for CO2 capacity and binding energetics. Solvent performance of these three CO2BOLs was evaluated by batch-wise CO2 uptake and release over multiple cycles. Synthesis of CO2BOLs, characterization, CO2 uptake, selectivity towards CO2 as well as solvent tolerance to water will be discussed.

Uncertainty analyses of CO2 plume expansion subsequent to wellbore CO2 leakage into aquifers  

SciTech Connect

In this study, we apply an uncertainty quantification (UQ) framework to CO2 sequestration problems. In one scenario, we look at the risk of wellbore leakage of CO2 into a shallow unconfined aquifer in an urban area; in another scenario, we study the effects of reservoir heterogeneity on CO2 migration. We combine various sampling approaches (quasi-Monte Carlo, probabilistic collocation, and adaptive sampling) in order to reduce the number of forward calculations while trying to fully explore the input parameter space and quantify the input uncertainty. The CO2 migration is simulated using the PNNL-developed simulator STOMP-CO2e (the water-salt-CO2 module). For computationally demanding simulations with 3D heterogeneity fields, we combined the framework with a scalable version module, eSTOMP, as the forward modeling simulator. We built response curves and response surfaces of model outputs with respect to input parameters, to look at the individual and combined effects, and identify and rank the significance of the input parameters.

On Leakage from Geologic Storage Reservoirs of CO2  

SciTech Connect

Large amounts of CO2 would need to be injected underground to achieve a significant reduction of atmospheric emissions. The large areal extent expected for CO2 plumes makes it likely that caprock imperfections will be encountered, such as fault zones or fractures, which may allow some CO2 to escape from the primary storage reservoir. Leakage of CO2 could also occur along wellbores. Concerns with escape of CO2 from a primary geologic storage reservoir include (1) acidification of groundwater resources, (2) asphyxiation hazard when leaking CO2 is discharged at the land surface, (3) increase in atmospheric concentrations of CO2, and (4) damage from a high-energy, eruptive discharge (if such discharge is physically possible). In order to gain public acceptance for geologic storage as a viable technology for reducing atmospheric emissions of CO2, it is necessary to address these issues and demonstrate that CO2 can be injected and stored safely in geologic formations.

A Comparative Study on the Environmental Impact of CO2 Supermarket Refrigeration Systems  

SciTech Connect

Supermarket refrigeration systems have high environmental impact due to their large refrigerant charge and high leak rates. Accordingly, the interest in using natural refrigerants, such as carbon dioxide (CO2), and new refrigerant blends with low GWP in such systems is increasing. In this paper, an open-source Life Cycle Climate Performance (LCCP) framework is presented and used to compare the environmental impact of three supermarket refrigeration systems. These systems include a transcritical CO2 booster system, a cascade CO2/N-40 system, and a baseline R-404A multiplex direct expansion system. The study is performed for cities representing different climates within the USA using EnergyPlus to simulate the systems' hourly performance. Finally, a parametric analysis is performed to study the impact of annual leak rate on the systems' LCCP.

Control Options and Integration Control Options and Integration Reaction Engineering International (REI) is optimizing the performance of, and reduce the technical risks associated with the combined application of low-NOx firing systems (LNFS) and post combustion controls through modeling, bench-scale testing, and field verification. Teaming with REI are the University of Utah and Brown University. During this two-year effort, REI will assess real-time monitoring equipment to evaluate waterwall wastage, soot formation, and burner stoichiometry, demonstrate analysis techniques to improve LNFS in combination with reburning/SNCR, assess selective catalytic reduction catalyst life, and develop UBC/fly ash separation processes. The REI program will be applicable to coal-fired boilers currently in use in the United States, including corner-, wall-, turbo-, and cyclone-fired units. However, the primary target of the research will be cyclone boilers, which are high NOx producing units and represent about 20% of the U.S. generating capacity. The results will also be applicable to all U.S. coals. The research will be divided into four key components:

PLAINS CO2 REDUCTION (PCOR) PARTNERSHIP  

SciTech Connect

During the period of October 1, 2003, through September 30, 2005, the Plains CO2 Reduction (PCOR) Partnership, identified geologic and terrestrial candidates for near-term practical and environmentally sound carbon dioxide (CO2) sequestration demonstrations in the heartland of North America. The PCOR Partnership region covered nine states and three Canadian provinces. The validation test candidates were further vetted to ensure that they represented projects with (1) commercial potential and (2) a mix that would support future projects both dependent and independent of CO2 monetization. This report uses the findings contained in the PCOR Partnership's two dozen topical reports and half-dozen fact sheets as well as the capabilities of its geographic information system-based Decision Support System to provide a concise picture of the sequestration potential for both terrestrial and geologic sequestration in the PCOR Partnership region based on assessments of sources, sinks, regulations, deployment issues, transportation, and capture and separation. The report also includes concise action plans for deployment and public education and outreach as well as a brief overview of the structure, development, and capabilities of the PCOR Partnership. The PCOR Partnership is one of seven regional partnerships under Phase I of the U.S. Department of Energy National Energy Technology Laboratory's Regional Carbon Sequestration Partnership program. The PCOR Partnership, comprising 49 public and private sector members, is led by the Energy & Environmental Research Center at the University of North Dakota. The international PCOR Partnership region includes the Canadian provinces of Alberta, Saskatchewan, and Manitoba and the states of Montana (part), Wyoming (part), North Dakota, South Dakota, Nebraska, Missouri, Iowa, Minnesota, and Wisconsin.

Post-Combustion CO2 Capture for Existing PC Boilers by Self-concentrating Amine Absorbent Post-Combustion CO2 Capture for Existing PC Boilers by Self-concentrating Amine Absorbent Project No.: DE-FE0004274 3H Company will evaluate the feasibility of its "Self-Concentrating Absorbent CO2 Capture Process." The process is based on amines in a non-aqueous solvent which, upon reaction with CO2, separate into two distinct phases: a CO2-rich liquid phase and a dilute lean phase. The proposed process offers several potential advantages. Preliminary experimental data show that the process has the potential of reducing the total regeneration energy by as much as 70 percent. The solvent has high working capacity, thus required solvent volume would be lower than that required in a currently available amine system. This results in lower pumping requirements, lower auxiliary power demands, and reduced equipment size. In addition, since the solvent is non-aqueous, corrosion issues would be reduced. During the three-year project, an engineering design supported by laboratory data and economic justification will be developed to construct and operate a slipstream demonstration facility at an E-ON power plant in the United States as a next stage of commercialization development.

Basic Illustration of the Phase Transitional Absorption Process. Hampton University researched a novel carbon dioxide (CO2) absorption concept, phase transitional absorption, that utilizes a two-part proprietary absorbent consisting of an activated agent dissolved in a solvent. Phase separation of the activated agent from the chemical solvent occurs during CO2 absorption and physical separation of the two phases exiting the absorber reduces the volume of process liquid requiring thermal regeneration. This unique aspect of phase transitional absorption also decreases the amount of energy (i.e., steam) required to liberate the CO2. If the proper liquid

IEP - Advanced NOx Emissions Control Regulatory Drivers Regulatory Drivers for Existing Coal-Fired Power Plants Regulatory and legislative requirements have predominantly driven the need to develop NOx control technologies for existing coal-fired power plants. The first driver was the Title IV acid rain program, established through the 1990 Clean Air Act Amendments (CAAA). This program included a two-phase strategy to reduce NOx emissions from coal-fired power plants – Phase I started January 1, 1996 and Phase II started January 1, 2000. The Title IV NOx program was implemented through unit-specific NOx emission rate limits ranging from 0.40 to 0.86 lb/MMBtu depending on the type of boiler/burner configuration and based on application of LNB technology.

Energy consumption analysis for CO2 separation from gas mixtures  

Science Journals Connector (OSTI)

Abstract CO2 separation is an energy intensive process, which plays an important role in both energy saving and CO2 capture and storage (CCS) implementation to deal with global warming. To quantitatively investigate the energy consumption of CO2 separation from different CO2 streams and analyze the effect of temperature, pressure and composition on energy consumption, in this work, the theoretical energy consumption of CO2 separation from flue gas, lime kiln gas, biogas and bio-syngas was calculated. The results show that the energy consumption of CO2 separation from flue gas is the highest and that from biogas is the lowest, and the concentration of CO2 is the most important factor affecting the energy consumption when the CO2 concentration is lower than 0.15 in mole fraction. Furthermore, if the CO2 captured from flue gases in CCS was replaced with that from biogases, i.e. bio-CO2, the energy saving would be equivalent to 7.31 million ton standard coal for China and 28.13 million ton standard coal globally, which corresponds to 0.30 billion US$ that can be saved for China and 1.36 billion US$ saved globally. This observation reveals the importance of trading fossil fuel-based CO2 with bio-CO2.

Industrial CO2 Removal: CO2 Capture from Ambient Air and Geological Sequestration  

SciTech Connect

This abstract and its accompanying presentation will provide an overview of two distinct industrial processes for removing carbon dioxide (CO2) from the atmosphere as a means of addressing anthropogenic climate change. The first of these is carbon dioxide capture and storage (CCS) coupled with large scale biomass production (hereafter referred to as bioCCS). The second is CO2 capture from ambient air via industrial systems (hereafter referred to as direct air capture (DAC)). In both systems, the captured CO2 would be injected into deep geologic formations so as to isolate it from the atmosphere. The technical literature is clear that both of these technologies are technically feasible as of today (IPCC, 2005; Keith, 2009; Lackner, 2009; Luckow et al., 2010; Ranjan and Herzog, 2011). What is uncertain is the relative cost of these industrial ambient-air CO2 removal systems when compared to other emissions mitigation measures, the ultimate timing and scale of their deployment, and the resolution of potential site specific constraints that would impact their ultimate commercial deployment.

Adsorption separation of CO2 from simulated flue gas mixtures by novel CO2 ''molecular basket'' adsorbents  

Science Journals Connector (OSTI)

Adsorption separation of CO2 from simulated flue gas mixtures containing CO2, O2, and N2 by using a novel CO2 ''molecular basket'' adsorbent was investigated in a flow adsorption separation system. The novel CO2 ''molecular basket'' adsorbents were developed by synthesising mesoporous molecular sieve MCM-41 and modifying it with polyethylenimine (PEI). The influence of operation conditions, including feed flow rate, temperature, feed CO2 concentration, and sweep gas flow rate, on the CO2 adsorption/desorption separation performance and CO2 breakthrough were examined. The CO2 adsorption capacity was 91.0 ml (STP)/g-PEI, which was 27 times higher than that of the MCM-41 alone. Further, the adsorbent showed separation selectivity of greater than 1000 for CO2/N2 ratio and approximately 180 for CO2/O2, which are significantly higher than those of the MCM-41, zeolites, and activated carbons. Cyclic adsorption/desorption measurements showed that the CO2 ''molecular basket'' adsorbent was stable at 75°C. However, the CO2 ''molecular basket'' adsorbent was not stable when the operation temperature was higher than 100°C.

Low NOx combustion system for heavy oil  

SciTech Connect

As a result of the increasing demand for white oil as one of countermeasures for pollution control and as a fuel for motor vehicle, coupled with the increasing import of heavy crude oil, heavy oils such as asphalt and distillation residue have become surplus in Japan. It is difficult by the conventional low NOx technology to control the NOx emission from the industrial small and medium capacity boilers, which use heavy oil as their fuels. The authors have been developing and improving NOx control technologies for boilers such as low NOx burners, two-stage combustion methods and so on. They have developed a new combustion system for heavy oil, which generates less NOx and soot than conventional systems, by applying the knowledge, obtained in the course of their development of Coal Partial Combustor (CPC). The conventional low NOx combustion method for oil firing boilers has been developed based on decreasing the flame temperature and delaying the combustion reaction. In the system, however, the heavy oil shall be combusted in the intense reducing atmosphere at the high flame temperature between 1,500 C and 1,600 C, and then the combustions gas shall be cooled and oxidized by two-stage combustion air. With this system, NOx emission can be suppressed below 100ppm (converted as O{sub 2}=4%).

CO2 exposure at pressure impacts metabolism and stress responses in the model sulfate-reducing bacterium Desulfovibrio vulgaris strain Hildenborough  

SciTech Connect

Geologic carbon dioxide (CO2) sequestration drives physical and geochemical changes in deep subsurface environments that impact indigenous microbial activities. The combined effects of pressurized CO2 on a model sulfate-reducing microorganism, Desulfovibrio vulgaris, have been assessed using a suite of genomic and kinetic measurements. Novel high-pressure NMR time-series measurements using 13C-lactate were used to track D. vulgaris metabolism. We identified cessation of respiration at CO2 pressures of 10 bar, 25 bar, 50 bar, and 80 bar. Concurrent experiments using N2 as the pressurizing phase had no negative effect on microbial respiration, as inferred from reduction of sulfate to sulfide. Complementary pressurized batch incubations and fluorescence microscopy measurements supported NMR observations, and indicated that non-respiring cells were mostly viable at 50 bar CO2 for at least four hours, and at 80 bar CO2 for two hours. The fraction of dead cells increased rapidly after four hours at 80 bar CO2. Transcriptomic (RNA-Seq) measurements on mRNA transcripts from CO2-incubated biomass indicated that cells up-regulated the production of certain amino acids (leucine, isoleucine) following CO2 exposure at elevated pressures, likely as part of a general stress response. Evidence for other poorly understood stress responses were also identified within RNA-Seq data, suggesting that while pressurized CO2 severely limits the growth and respiration of D. vulgaris cells, biomass retains intact cell membranes at pressures up to 80 bar CO2. Together, these data show that geologic sequestration of CO2 may have significant impacts on rates of sulfate reduction in many deep subsurface environments where this metabolism is a key respiratory process.

CO2 sorption and reaction kinetic performance of K2CO3/AC in low temperature and CO2 concentration  

Science Journals Connector (OSTI)

Abstract Reducing or removing CO2 is critical to the confined spaces such as submarines, space-crafts or aircrafts while using solid sorbents has been regarded as a promising method. In this work, K2CO3 loaded on activated carbon (K2CO3/AC) was developed as a new and regenerable sorbent for CO2 removing in confined spaces. CO2 sorption performances of K2CO3/AC were investigated under different conditions by varying the K2CO3 loadings, CO2 concentrations, H2O concentrations, CO2 sorption temperatures and water pretreatment durations as well as the purge gas flow rates. The CO2 sorption capacity and carbonation conversion of K2CO3/AC decrease with increasing temperature and increase with increasing mole ratio of H2O concentration over CO2 concentration. Sufficient water vapor pretreatment is found to be beneficial to the sorption-enhanced performance. Increasing flow rate will weaken the CO2 sorption performance. The carbonation kinetics was also investigated with the correlation between the shrinking core model and experimental data. Additionally, the sorbent is proved to be regenerable and stable during 20-cycle CO2 sorption–desorption experiments. K2CO3/AC presents high carbonation conversion efficiency, high thermal stability, and low dependency on CO2 partial pressure. Therefore, it can be considered as a new option for CO2 removal in confined spaces.

Supersonic Technology for CO2 Capture: A High Efficiency Inertial CO2 Extraction System  

SciTech Connect

IMPACCT Project: Researchers at ATK and ACENT Laboratories are developing a device that relies on aerospace wind-tunnel technologies to turn CO2 into a condensed solid for collection and capture. ATK’s design incorporates a special nozzle that converges and diverges to expand flue gas, thereby cooling it off and turning the CO2 into solid particles which are removed from the system by a cyclonic separator. This technology is mechanically simple, contains no moving parts and generates no chemical waste, making it inexpensive to construct and operate, readily scalable, and easily integrated into existing facilities. The increase in the cost to coal-fired power plants associated with introduction of this system would be 50% less than current technologies.

System-level modeling for geological storage of CO2  

SciTech Connect

One way to reduce the effects of anthropogenic greenhousegases on climate is to inject carbon dioxide (CO2) from industrialsources into deep geological formations such as brine formations ordepleted oil or gas reservoirs. Research has and is being conducted toimprove understanding of factors affecting particular aspects ofgeological CO2 storage, such as performance, capacity, and health, safetyand environmental (HSE) issues, as well as to lower the cost of CO2capture and related processes. However, there has been less emphasis todate on system-level analyses of geological CO2 storage that considergeological, economic, and environmental issues by linking detailedrepresentations of engineering components and associated economic models.The objective of this study is to develop a system-level model forgeological CO2 storage, including CO2 capture and separation,compression, pipeline transportation to the storage site, and CO2injection. Within our system model we are incorporating detailedreservoir simulations of CO2 injection and potential leakage withassociated HSE effects. The platform of the system-level modelingisGoldSim [GoldSim, 2006]. The application of the system model is focusedon evaluating the feasibility of carbon sequestration with enhanced gasrecovery (CSEGR) in the Rio Vista region of California. The reservoirsimulations are performed using a special module of the TOUGH2 simulator,EOS7C, for multicomponent gas mixtures of methane and CO2 or methane andnitrogen. Using this approach, the economic benefits of enhanced gasrecovery can be directly weighed against the costs, risks, and benefitsof CO2 injection.

The combustor design and operating conditions will be optimized to achieve atypical flue gas conditions. This approach will not only suppress NOx generation during combustion but also further reduce NOx over a downstream catalytic reactor that does not require addition of an external reductant, such as ammonia.

Oxygen supply for oxyfuel CO2 capture  

Science Journals Connector (OSTI)

This paper presents the results of a study to develop Air Products’ air separation unit (ASU) offerings for oxyfuel coal CO2 capture projects. A scalable “reference plant” concept is described to match particular sizes of power generation equipment, taking into account factors such as safety, reliability, operating flexibility, efficiency, and low capital cost. We describe the selection of a process cycle to exploit the low purity requirements, as well as the options for compression machinery and drivers as the scale of the plant increases and the sizes of referenced equipment limit the possibilities. We also explore integration with other elements of the system, such as preheating condensate or heating and expanding pressurised nitrogen. In addition, we consider how the ASU affects the flexibility of the oxyfuel system and discuss how its power consumption can be reduced during periods of high power demand. Finally, the advantages and disadvantages of different execution strategies for air separation unit projects are discussed, as well as alternative commercial models for the supply of oxygen.

A set of geostatistical-based Monte Carlo simulations of CO2-oil-water flow and reactive transport in the Morrow formation are conducted for global sensitivity and statistical analysis of the major uncertainty metrics: net CO2 injection, cumulative oil production, cumulative gas (CH4) production, and net water injection. A global sensitivity and response surface analysis indicates that reservoir permeability, porosity, and thickness are the major intrinsic reservoir parameters that control net CO2 injection/storage and oil/gas recovery rates. The well spacing and the initial water saturation also have large impact on the oil/gas recovery rates. Further, this study has revealed key insights into the potential behavior and the operational parameters of CO2 sequestration at CO2-EOR s...

OXYGEN ENHANCED COMBUSTION FOR NOx CONTROL  

SciTech Connect

Conventional wisdom says adding oxygen to a combustion system enhances product throughput, system efficiency, and, unless special care is taken, increases NOx emissions. This increase in NOx emissions is typically due to elevated flame temperatures associated with oxygen use leading to added thermal NOx formation. Innovative low flame temperature oxy-fuel burner designs have been developed and commercialized to minimize both thermal and fuel NOx formation for gas and oil fired industrial furnaces. To be effective these systems require close to 100% oxy-fuel combustion and the cost of oxygen is paid for by fuel savings and other benefits. For applications to coal-fired utility boilers at the current cost of oxygen, however, it is not economically feasible to use 100% oxygen for NOx control. In spite of this conventional wisdom, Praxair and its team members, in partnership with the US Department of Energy National Energy Technology Laboratory, have developed a novel way to use oxygen to reduce NOx emissions without resorting to complete oxy-fuel conversion. In this concept oxygen is added to the combustion process to enhance operation of a low NOx combustion system. Only a small fraction of combustion air is replaced with oxygen in the process. By selectively adding oxygen to a low NOx combustion system it is possible to reduce NOx emissions from nitrogen-containing fuels, including pulverized coal, while improving combustion characteristics such as unburned carbon. A combination of experimental work and modeling was used to define how well oxygen enhanced combustion could reduce NOx emissions. The results of this work suggest that small amounts of oxygen replacement can reduce the NOx emissions as compared to the air-alone system. NOx emissions significantly below 0.15 lbs/MMBtu were measured. Oxygen addition was also shown to reduce carbon in ash. Comparison of the costs of using oxygen for NOx control against competing technologies, such as SCR, show that this concept offers substantial savings over SCR and is an economically attractive alternative to purchasing NOx credits or installing other conventional technologies. In conjunction with the development of oxygen based low NOx technology, Praxair also worked on developing the economically enhancing oxygen transport membrane (OTM) technology which is ideally suited for integration with combustion systems to achieve further significant cost reductions and efficiency improvements. This OTM oxygen production technology is based on ceramic mixed conductor membranes that operate at high temperatures and can be operated in a pressure driven mode to separate oxygen with infinite selectivity and high flux. An OTM material was selected and characterized. OTM elements were successfully fabricated. A single tube OTM reactor was designed and assembled. Testing of dense OTM elements was conducted with promising oxygen flux results of 100% of target flux. However, based on current natural gas prices and stand-alone air separation processes, ceramic membranes do not offer an economic advantage for this application. Under a different DOE-NETL Cooperative Agreement, Praxair is continuing to develop oxygen transport membranes for the Advanced Boiler where the economics appear more attractive.

Hybrid Membrane/Absorption Process for Post-combustion CO2 Capture  

SciTech Connect

This report summarizes scientific/technical progress made for bench-scale membrane contactor technology for post-combustion CO2 capture from DOE Contract No. DE-FE-0004787. Budget Period 1 (BP1) membrane absorber, Budget Period 2 (BP2) membrane desorber and Budget Period 3 (BP3) integrated system and field testing studies have been completed successfully and met or exceeded the technical targets (? 90% CO2 removal and CO2 purity of 97% in one membrane stage). Significant breakthroughs are summarized below: BP1 research: The feasibility of utilizing the poly (ether ether ketone), PEEK, based hollow fiber contractor (HFC) in combination with chemical solvents to separate and capture at least 90% of the CO2 from simulated flue gases has been successfully established. Excellent progress has been made as we have achieved the BP1 goal: ? 1,000 membrane intrinsic CO2 permeance, ? 90% CO2 removal in one stage, ? 2 psi gas side pressure drop, and ? 1 (sec)-1 mass transfer coefficient. Initial test results also show that the CO2 capture performance, using activated Methyl Diethanol Amine (aMDEA) solvent, was not affected by flue gas contaminants O2 (~3%), NO2 (66 ppmv), and SO2 (145 ppmv). BP2 research: The feasibility of utilizing the PEEK HFC for CO2-loaded solvent regeneration has been successfully established High CO2 stripping flux, one order of magnitude higher than CO2 absorption flux, have been achieved. Refined economic evaluation based on BP1 membrane absorber and BP2 membrane desorber laboratory test data indicate that the CO2 capture costs are 36% lower than DOE’s benchmark amine absorption technology. BP3 research: A bench-scale system utilizing a membrane absorber and desorber was integrated into a continuous CO2 capture process using contactors containing 10 to 20 ft2 of membrane area. The integrated process operation was stable through a 100-hour laboratory test, utilizing a simulated flue gas stream. Greater than 90% CO2 capture combined with 97% CO2 product purity was achieved throughout the test. Membrane contactor modules have been scaled from bench scale 2-inch diameter by 12-inch long (20 ft2 membrane surface area) modules to 4-inch diameter by 60-inch long pilot scale modules (165 ft2 membrane surface area). Pilot scale modules were tested in an integrated absorption/regeneration system for CO2 capture field tests at a coal-fired power plant (Midwest Generation’s Will County Station located in Romeoville, IL). Absorption and regeneration contactors were constructed utilizing high performance super-hydrophobic, nano-porous PEEK membranes with CO2 gas permeance of 2,000 GPU and a 1,000 GPU, respectively. Field tests using aMDEA solvent achieved greater than 90% CO2 removal in a single stage. The absorption mass transfer coefficient was 1.2 (sec)-1, exceeding the initial target of 1.0 (sec)-1. This mass transfer coefficient is over one order of magnitude greater than that of conventional gas/liquid contacting equipment. The economic evaluation based on field tests data indicates that the CO2 capture cost associated with membrane contactor technology is $54.69 (Yr 2011$)/tonne of CO2 captured when using aMDEA as a solvent. It is projected that the DOE’s 2025 cost goal of $40 (Yr 2011$)/tonne of CO2 captured can be met by decreasing membrane module cost and by utilizing advanced CO2 capture solvents. In the second stage of the field test, an advanced solvent, Hitachi’s H3-1 was utilized. The use of H3-1 solvent increased mass transfer coefficient by 17% as compared to aMDEA solvent. The high mass transfer coefficient of H3-1 solvent combined with much more favorable solvent regeneration requirements, indicate that the projected savings achievable with membrane contactor process can be further improved. H3-1 solvent will be used in the next pilot-scale development phase. The integrated absorption/regeneration process design and high performance membrane contactors developed in the current bench-scale program will be used as the base technology for future pilot-scale development.

Multi-Pollutant Emissions Control: Pilot Plant Study of Technologies for Reducing Hg, SO3, NOx and CO2 Emissions  

SciTech Connect

A slipstream pilot plant was built and operated to investigate technology to adsorb mercury (Hg) onto the existing particulate (i.e., fly ash) by cooling flue gas to 200-240 F with a Ljungstrom-type air heater or with water spray. The mercury on the fly ash was then captured in an electrostatic precipitator (ESP). An alkaline material, magnesium hydroxide (Mg(OH){sub 2}), is injected into flue gas upstream of the air heater to control sulfur trioxide (SO{sub 3}), which prevents acid condensation and corrosion of the air heater and ductwork. The slipstream was taken from a bituminous coal-fired power plant. During this contract, Plant Design and Construction (Task 1), Start Up and Maintenance (Task 2), Baseline Testing (Task 3), Sorbent Testing (Task 4), Parametric Testing (Task 5), Humidification Tests (Task 6), Long-Term Testing (Task 7), and a Corrosion Study (Task 8) were completed. The Mercury Stability Study (Task 9), ESP Report (Task 11), Air Heater Report (Task 12) and Final Report (Task 14) were completed. These aspects of the project, as well as progress on Public Outreach (Task 15), are discussed in detail in this final report. Over 90% mercury removal was demonstrated by cooling the flue gas to 200-210 F at the ESP inlet; baseline conditions with 290 F flue gas gave about 26% removal. Mercury removal is sensitive to flue gas temperature and carbon content of fly ash. At 200-210 F, both elemental and oxidized mercury were effectively captured at the ESP. Mg(OH){sub 2} injection proved effective for removal of SO{sub 3} and eliminated rapid fouling of the air heater. The pilot ESP performed satisfactorily at low temperature conditions. Mercury volatility and leaching tests did not show any stability problems. No significant corrosion was detected at the air heater or on corrosion coupons at the ESP. The results justify larger-scale testing/demonstration of the technology. These conclusions are presented and discussed in two presentations given in July and September of 2005 and are included in Appendices E and F.

Implementation of the El Mar (Delaware) Unit CO2 flood  

SciTech Connect

Union Royalty, Inc., Amoco Production Company, and Enron Liquids Pipeline Company recently announced that they have commenced operations of an innovative enhanced oil recovery project at the El Mar (Delaware) Unit in Loving County, Texas, about 100 miles west of Midland, Texas. The project will convert the unit`s existing oil recovery system from a secondary (waterflood) system to a tertiary (CO2 flood) system designed to use carbon dioxide and water to increase crude oil production from the unit. What makes this EOR project unique is the creative deal structured by the partners involved. Amoco, Union Royalty, and Enron have worked out an unprecedented arrangement whereby Amoco essentially trades CO2 for an interest in Union Royalty`s future oil production from the unit. By pioneering this innovative deal new production life has been restored to a field that otherwise might dry up. Enron is participating in the project by transporting CO2 to the unit via a 40-mile expansion of its Central Basin Pipeline system from the Dollarhide oil field in Andrews county, Texas. The project will be implemented in four phases. The first phase in operation today comprises seven CO2 injection wells which have begun to process the reservoir with CO2. Plans now call for more CO2 injectors to be installed during the next three to five years until a total of 65 CO2 injectors and an on-site CO2 compression facility serve the unit`s 70 production wells.

NETL: Low-Pressure Membrane Contactors for CO2 Capture  

NLE Websites -- All DOE Office Websites (Extended Search)

Low-Pressure Membrane Contactors for CO2 Capture Low-Pressure Membrane Contactors for CO2 Capture Project No.: DE-FE0007553 Membrane Technology and Research, Inc. (MTR) is developing a new type of membrane contactor (or mega-module) to separate carbon dioxide (CO2) from power plant flue gas. This module's membrane area is 500 square meters, 20 to 25 times larger than that of current modules used for CO2 capture. A 500-MWe coal power plant requires 0.5 to 1 million square meters of membrane to achieve 90 percent CO2 capture. The new mega-modules can drastically reduce the cost, complexity, and footprint of commercial-scale membrane module integration. Energy savings due to low-pressure drops for gases circulated through the modules, as well as improved countercurrent flow, are additional benefits. The feasibility of using mega-modules in several different hybrid process designs is being evaluated for future development potential.

Enhanced Combustion Low NOx Pulverized Coal Burner  

SciTech Connect

For more than two decades, Alstom Power Inc. (Alstom) has developed a range of low cost, infurnace technologies for NOx emissions control for the domestic U.S. pulverized coal fired boiler market. This includes Alstom's internally developed TFS 2000{trademark} firing system, and various enhancements to it developed in concert with the U.S. Department of Energy. As of the date of this report, more than 270 units representing approximately 80,000 MWe of domestic coal fired capacity have been retrofit with Alstom low NOx technology. Best of class emissions range from 0.18 lb/MMBtu for bituminous coal to 0.10 lb/MMBtu for subbituminous coal, with typical levels at 0.24 lb/MMBtu and 0.13 lb/MMBtu, respectively. Despite these gains, NOx emissions limits in the U.S. continue to ratchet down for new and existing boiler equipment. On March 10, 2005, the Environmental Protection Agency (EPA) announced the Clean Air Interstate Rule (CAIR). CAIR requires 25 Eastern states to reduce NOx emissions from the power generation sector by 1.7 million tons in 2009 and 2.0 million tons by 2015. Low cost solutions to meet such regulations, and in particular those that can avoid the need for a costly selective catalytic reduction system (SCR), provide a strong incentive to continue to improve low NOx firing system technology to meet current and anticipated NOx control regulations. The overall objective of the work is to develop an enhanced combustion, low NOx pulverized coal burner, which, when integrated with Alstom's state-of-the-art, globally air staged low NOx firing systems will provide a means to achieve: Less than 0.15 lb/MMBtu NOx emissions when firing a high volatile Eastern or Western bituminous coal, Less than 0.10 lb/MMBtu NOx emissions when firing a subbituminous coal, NOx reduction costs at least 25% lower than the costs of an SCR, Validation of the NOx control technology developed through large (15 MWt) pilot scale demonstration, and Documentation required for economic evaluation and commercial application. During the project performance period, Alstom performed computational fluid dynamics (CFD) modeling and large pilot scale combustion testing in its Industrial Scale Burner Facility (ISBF) at its U.S. Power Plant Laboratories facility in Windsor, Connecticut in support of these objectives. The NOx reduction approach was to optimize near-field combustion to ensure that minimum NOx emissions are achieved with minimal impact on unburned carbon in ash, slagging and fouling, corrosion, and flame stability/turn-down. Several iterations of CFD and combustion testing on a Midwest coal led to an optimized design, which was extensively combustion tested on a range of coals. The data from these tests were then used to validate system costs and benefits versus SCR. Three coals were evaluated during the bench-scale and large pilot-scale testing tasks. The three coals ranged from a very reactive subbituminous coal to a moderately reactive Western bituminous coal to a much less reactive Midwest bituminous coal. Bench-scale testing was comprised of standard ASTM properties evaluation, plus more detailed characterization of fuel properties through drop tube furnace testing and thermogravimetric analysis. Bench-scale characterization of the three test coals showed that both NOx emissions and combustion performance are a strong function of coal properties. The more reactive coals evolved more of their fuel bound nitrogen in the substoichiometric main burner zone than less reactive coal, resulting in the potential for lower NOx emissions. From a combustion point of view, the more reactive coals also showed lower carbon in ash and CO values than the less reactive coal at any given main burner zone stoichiometry. According to bench-scale results, the subbituminous coal was found to be the most amenable to both low NOx, and acceptably low combustibles in the flue gas, in an air staged low NOx system. The Midwest bituminous coal, by contrast, was predicted to be the most challenging of the three coals, with the Western bituminous coal predicted to beh

Combustion-Assisted CO2 Capture Using MECC Membranes  

SciTech Connect

Mixed Electron and Carbonate ion Conductor (MECC) membranes have been proposed as a means to separate CO2 from power plant flue gas. Here a modified MECC CO2 capture process is analyzed that supplements retentate pressurization and permeate evacuation as a means to create a CO2 driving force with a process assisted by the catalytic combustion of syngas on the permeate side of the membrane. The combustion reactions consume transported oxygen, making it unavailable for the backwards transport reaction. With this change, the MECC capture system becomes exothermic, and steam for electricity production may be generated from the waste heat. Greater than 90% of the CO2 in the flue gas may be captured, and a compressed CO2 product stream is produced. A fossil-fueled power plant using this process would consume 14% more fuel per unit electricity produced than a power plant with no CO2 capture system, and has the potential to meet U.S. DOE s goal that deployment of a CO2 capture system at a fossil-fueled power plant should not increase the cost of electricity from the combined facility by more than 30%.

Integrated Energy System with Beneficial Carbon Dioxide (CO2) Use  

SciTech Connect

To address the public concerns regarding the consequences of climate change from anthropogenic carbon dioxide (CO2) emissions, the U.S. Department of Energy National Energy Technology Laboratory (DOE-NETL) is actively funding a CO2 management program to develop technologies capable of reducing the CO2 emissions from fossil fuel power plants and other industrial facilities. Over the past decade, this program has focused on reducing the costs of carbon capture and storage technologies. Recently, DOE-NETL launched an alternative CO2 mitigation program focusing on beneficial CO2 reuse and supporting the development of technologies that mitigate emissions by converting CO2 to solid mineral form that can be utilized for enhanced oil recovery, in the manufacturing of concrete or as a benign landfill, in the production of valuable chemicals and/or fuels. This project was selected as a CO2 reuse activity which would conduct research and development (R&D) at the pilot scale via a cost-shared Cooperative Agreement number DE-FE0001099 with DOE-NETL and would utilize funds setaside by the American Recovery and Reinvestment Act (ARRA) of 2009 for Industrial Carbon Capture and Sequestration R&D,

METHANE de-NOx® METHANE de-NOx® The Gas Technology Institute (GTI) is teaming with the All-Russian Thermal Engineering Institute and DB Riley to develop a pulverized-coal (PC)-combustion system that is an extension of IGT's METHANE de-NOx® technology. The technology is composed of a novel PC burner design using natural gas fired coal preheating developed and demonstrated in Russia, LNBs with internal combustion staging, and additional natural gas injection with overfire air. The coal is preheated at elevated temperatures (up to 1500oF) in oxygen deficient conditions prior to combustion. Coal preheat releases fuel-bound nitrogen together with volatiles present in the coal. These conditions promote the conversion of fuel-bound nitrogen to molecular nitrogen rather than to NOx.

ENHANCED PRACTICAL PHOTOSYNTHETIC CO2 MITIGATION

This report documents significant achievements in the Enhanced Practical Photosynthetic CO{sub 2} Mitigation project during the period from 10/2/2001 through 10/01/2002. This report marks the end of year 2 of a three-year project as well as the milestone date for completion of Phase I activities. This report includes our current status and defines the steps being taken to ensure that we meet the project goals by the end of year 3. As indicated in the list of accomplishments below our current efforts are focused on evaluating candidate organisms and growth surfaces, preparing to conduct long-term tests in the bench-scale bioreactor test systems, and scaling-up the test facilities from bench scale to pilot scale. Specific results and accomplishments for the third quarter of 2002 include: Organisms and Growth Surfaces: (1) Test results continue to indicate that thermophilic cyanobacteria have significant advantages as agents for practical photosynthetic CO{sub 2} mitigation before mesophilic forms. (2) Additional thermal features with developed cyanobacterial mats, which might be calcium resistant, were found in YNP. (3) Back to back tests show that there is no detectable difference in the growth of isolate 1.2 s.c. (2) in standard and Ca-modified BG-11 medium. The doubling time for both cases was about 12 hours. (4) The cultivation of cyanobacteria in Ca-BG medium should proceed in the pH range between 7 and 7.4, but this suggestion requires additional experiments. (5) Cyanobacteria can be grown in media where sodium is present at trace levels. (6) Ca{sup 2+} enriched medium can be used as a sink for CO{sub 2} under alkaline conditions. (7) Cyanobacteria are able to generate cones of filaments on travertine surfaces. [Travertine is a mixture of CaCO{sub 3} and CaSO{sub 4}]. We hypothesize that SO{sub 4}{sup 2-} stimulates the generation of such cones, because they are not almost generated on CaCO3 surface. On the other hand, we know that plant gas contains elevated concentrations of SO{sub 4}{sup 2-}. We may speculate that the introduction of 11.2 isolate in CRF might significantly increase the productivity of such facility. It is possible that a higher colonization potential for the screens may allow a higher surface productivity than some of the other isolates. (8) The colonization of Omnisil surface is an auto-inducible and time-requiring process. (9) Omnisil coupons should be treated under pH control, preferably using KOH. Bioreactor support systems and test facilities: (1) The pilot-scale bioreactor construction and debugging is continuing on schedule. Tests of the ''natural'' lighting system have shown acceptable levels of illumination for the bioreactor screens using only collected sunlight. (2) Flow control inserts have been designed for the CRF-2 screens, which require header pipes for flow distribution and control. A staggered drilled-hole design and a thick shim design have both shown acceptable performance results (little to no clogging, uniform flow, ability to load algae on to the screen). They will both be tested in the CRF-2 to see which performs the best over long durations, and the best performing design will be used for the pilot scale bioreactor screens.

SOx-NOx-Rox Box{trademark} flue gas clean-up demonstration. Final report  

SciTech Connect

Babcock and Wilcox`s (B and W) SOx-NOx-Rox Box{trademark} process effectively removes SOx, NOx and particulate (Rox) from flue gas generated from coal-fired boilers in a single unit operation, a high temperature baghouse. The SNRB technology utilizes dry sorbent injection upstream of the baghouse for removal of SOx and ammonia injection upstream of a zeolitic selective catalytic reduction (SCR) catalyst incorporated in the baghouse to reduce NOx emissions. Because the SOx and NOx removal processes require operation at elevated gas temperatures (800--900 F) for high removal efficiency, high-temperature fabric filter bags are used in the baghouse. The SNRB technology evolved from the bench and laboratory pilot scale to be successfully demonstrated at the 5-MWe field scale. This report represents the completion of Milestone M14 as specified in the Work Plan. B and W tested the SNRB pollution control system at a 5-MWe demonstration facility at Ohio Edison`s R.E. Burger Plant located near Shadyside, Ohio. The design and operation were influenced by the results from laboratory pilot testing at B and W`s Alliance Research Center. The intent was to demonstrate the commercial feasibility of the SNRB process. The SNRB facility treated a 30,000 ACFM flue gas slipstream from Boiler No. 8. Operation of the facility began in May 1992 and was completed in May 1993. About 2,300 hours of high-temperature operation were achieved. The main emissions control performance goals of: greater than 70% SO{sub 2} removal using a calcium-based sorbent; greater than 90% NOx removal with minimal ammonia slip; and particulate emissions in compliance with the New Source Performance Standards (NSPS) of 0.03 lb/million Btu were exceeded simultaneously in the demonstration program when the facility was operated at optimal conditions. Testing also showed significant reductions in emissions of some hazardous air pollutants.

CO2-selective, Hybrid Membranes by Silation of Alumina  

SciTech Connect

Hybrid membranes are feasible candidates for the separation of CO2 from gas produced in coal-based power generation since they have the potential to combine the high selectivity of polymer membranes and the high permeability of inorganic membranes. An interesting method for producing hybrid membranes is the silation of an inorganic membrane. In this method, trichloro- or alkoxy-silanes interact with hydroxyl groups on the surface of ?-AlO3 or TiO2, binding organic groups to that surface. By varying the length of these organic groups on the organosilane, it should be possible to tailor the effective pore size of the membrane. Similarly, the addition of “CO2-phillic” groups to the silating agent allows for the careful control of surface affinity and the enhancement of surface diffusion mechanisms. This method of producing hybrid membranes selective to CO2 was first attempted by Hyun [1] who silated TiO2 with phenyltriethoxysilane. Later, Way [2] silated ?-AlO3 with octadecyltrichlorosilane. Both researchers were successful in producing membranes with improved selectivity toward CO2, but permeability was not maintained at a commercially applicable level. XPS data indicated that the silating agent did not penetrate into the membrane pores and separation actually occurred in a thin “polymer-like” surface layer. The present study attempts to overcome the mass transfer problems associated with this technique by producing the desired monolayer coverage of silane, and thus develop a highly-permeable CO2-selective hybrid membrane.

Surface Ocean CO2 Atlas (SOCAT) gridded data products  

SciTech Connect

A well documented, publicly available, global data set for surface ocean carbon dioxide (CO2) parameters has been called for by international groups for nearly two decades. The Surface Ocean CO2 Atlas (SOCAT) project was initiated by the international marine carbon science community in 2007 with the aim of providing a comprehensive, publicly available, regularly updated, global data set of marine surface CO2, which had been subject to quality control (QC). SOCAT version 1.5 was made public in September 2011 and holds 6.3 million quality controlled surface CO2 data from the global oceans and coastal seas, spanning four decades (1968 2007). The SOCAT gridded data is the second data product to come from the SOCAT project. Recognizing that some groups may have trouble working with millions of measurements, the SOCAT gridded product was generated to provide a robust regularly spaced fCO2 product with minimal spatial and temporal interpolation which should be easier to work with for many applications. Gridded SOCAT is rich with information that has not been fully explored yet, but also contains biases and limitations that the user needs to recognize and address.

Alstom's Chemical Looping Combustion Technology with CO2 Capture for New and Existing Coal-Fired Power Plants Alstom's Chemical Looping Combustion Technology with CO2 Capture for New and Existing Coal-Fired Power Plants Project No.: DE-FE0009484 Alstom is advancing the development of Limestone Chemical Looping Combustion (LCL-C(tm)) technology. Chemical looping has no direct contact between air and fuel. The looping process usually utilizes oxygen from a metal carrier, but in this case, limestone is used. Economic evaluations will be made of four LCL-C plant configurations. The base configuration plant has already been completed and will be updated from previous reports. A second case will compare the effects of designing the reducer reactor using CFB sizing standards. A third case will investigate the effects of using a pressurized reducer reactor. Pressurizing the reducer reduces the reactor size and reduces the amount of compression required for the CO2 outlet gas stream. A fourth case will investigate the use of an advanced ultra-supercritical (USC) steam cycle. The advanced USC steam cycle should increase overall plant efficiency and lower the cost of electricity. Mass and energy balances will be done for each case. The four LCL-CTM cases will be compared against a supercritical pulverized coal-fired plant without CO2 capture.

Ion Advanced Solvent CO2 Capture Pilot Project Ion Advanced Solvent CO2 Capture Pilot Project Project No.: DE-FE0013303 ION Engineering is conducting small pilot-scale (~ 0.7 MW) testing of an advanced CO2 capture solvent technology that has previously undergone bench-scale testing. The small pilot-scale testing will involve continuous long-term operation in order to gather the necessary data ultimately required for further scale-up. Activities will include the design and fabrication of the 0.5-0.7 MWe (equivalent) slipstream pilot plant; scale-up of solvent manufacturing; testing, data collection, and analysis of solvent performance; degradation and air emission analysis; modeling and simulation for the detailed preliminary and final techno-economic analyses; and decommissioning of pilot plant equipment upon completion of solvent testing. The advanced solvent is anticipated to have significant operating and capital cost advantages over other solvents currently in development. Advantages include significant reductions in parasitic load and liquid flow rates which directly translate to smaller more efficient CO2 capture processes. Make-up water and amine emissions rates will be examined during this project. There is the potential that additional solvent, system, and integration savings will be identified, which could result in further operating and capital cost reductions.

Reducing CO2 in the transport sector in Japan  

Science Journals Connector (OSTI)

In this paper, we have investigated the cost-effectiveness of alternative fuel vehicles as a measure for CO2 reduction. Computed results indicate that the installation of alternative fuel vehicles is much more expensive than fuel switching in industry or the power generation sector. However, some economic incentives will make the price go down to the level at which alternative fuel vehicles are competitive with conventional vehicles. At the same time, mass production makes their prices go down although it is rather expensive at present. Then, we developed the scenarios in which CO2 emissions could be stabilised at the level in 1990. In the higher demand case (1.2%/yr.), it is indispensable to introduce alternative fuel vehicles into the market. Our model selects electric vehicles and compressed natural gas vehicles as cost-effective options. In the scenario where carbon tax revenue is not offset by subsidy, we have to impose prohibitively high carbon tax to suppress CO2. However, CO2 emission can be suppressed by a reasonable carbon tax if the tax revenue is returned to the market to subsidise alternative fuel vehicles and their infrastructures.

NOx Control Options and Integration for US Coal Fired Boilers  

SciTech Connect

This is the sixteenth Quarterly Technical Report for DOE Cooperative Agreement No: DEFC26-00NT40753. The goal of the project is to develop cost effective analysis tools and techniques for demonstrating and evaluating low NOx control strategies and their possible impact on boiler performance for boilers firing US coals. The Electric Power Research Institute (EPRI) is providing co-funding for this program. During an unplanned outage, damage occurred to the electrochemical noise corrosion probes installed at the AEP Gavin plant; testing is expected to resume in August. The KEMCOP corrosion coupons were not affected by the unplanned outage; the coupons were removed and sent for analysis. BYU conducted a series of tests before the ISSR lab was relocated. Ammonia adsorption experiments provided clear evidence of the types of acidic sites present on catalyst surfaces. Data collected this quarter indicate that surface sulfation decreases Lewis acid site concentrations for all catalysts thus far studied, confirming that catalytic activity under commercial coal-based SCR conditions occurs primarily on Br{o}nsted acid sites and would be susceptible to basic impurities such as alkali and alkaline earth oxides, chlorides, and sulfates. SCR activity tests based on MS analysis showed that increasing sulfation generally increases NO reduction activity for both 0% and 1% vanadia catalysts. During this quarter, the slipstream reactor at Rockport operated for 720 hours on flue gas. Catalyst exposure time reached 4500 hours since installation. The reactor is out of service at the Rockport plant and plans are being made to move it to the Gadsden Plant. At Gadsden, modifications have begun in preparation for installation of the slipstream reactor next quarter.

Biomimetic Membrane for CO2 Capture from Flue Gas  

SciTech Connect

These Phase III experiments successfully addressed several issues needed to characterize a permeator system for application to a pulverized coal (PC) burning furnace/boiler assuming typical post-combustion cleanup devices in place. We completed key laboratory stage optimization and modeling efforts needed to move towards larger scale testing. The SOPO addressed six areas. Task 1--Post-Combustion Particle Cleanup--The first object was to determine if the Carbozyme permeator performance was likely to be reduced by particles (materials) in the flue gas stream that would either obstruct the mouth of the hollow fibers (HF) or stick to the HF bore wall surface. The second, based on the Acceptance Standards (see below), was to determine whether it would be preferable to clean the inlet gas stream (removing acid gases and particulates) or to develop methods to clean the Carbozyme permeator if performance declined due to HF block. We concluded that condensation of particle and particulate emissions, in the heat exchanger, could result in the formation of very sticky sulfate aerosols with a strong likelihood of obtruding the HF. These must be managed carefully and minimized to near-zero status before entering the permeator inlet stream. More extensive post-combustion cleanup is expected to be a necessary expense, independent of CO{sub 2} capture technology This finding is in agreement with views now emerging in the literature for a variety of CO{sub 2} capture methods. Task 2--Water Condensation--The key goal was to monitor and control temperature distributions within the permeator and between the permeator and its surroundings to determine whether water condensation in the pores or the HF bore would block flow, decreasing performance. A heat transfer fluid and delivery system were developed and employed. The result was near isothermal performance that avoided all instances of flow block. Direct thermocouple measurements provided the basis for developing a heat transfer model that supports prediction of heat transfer profiles for larger permeators Tasks 3. 4.1, 4.2--Temperature Range of Enzymes--The goal was to determine if the enzyme operating temperature would limit the range of thermal conditions available to the capture system. We demonstrated the ability of various isozymes (enzyme variants) to operate from 4-85 C. Consequently, the operating characteristics of the enzyme are not a controlling factor. Further, any isozyme whose upper temperature bound is at least 10 C greater than that of the planned inlet temperature will be stable under unanticipated, uncontrolled 'hiccups' in power plant operation. Task 4.4, 4.4--Examination of the Effects of SOx and NOx on Enzyme Activity (Development of Flue Gas Composition Acceptance Standards)--The purpose was to define the inlet gas profile boundaries. We examined the potential adverse effects of flue gas constituents including different acids from to develop an acceptance standard and compared these values to actual PC flue gas composition. Potential issues include changes in pH, accumulation of specific inhibitory anions and cations. A model was developed and validated by test with a SO{sub 2}-laden stream. The predicted and actual data very largely coincided. The model predicted feed stream requirements to allow continuous operation in excess of 2500 hours. We developed operational (physical and chemical) strategies to avoid or ameliorate these effects. Avoidance, the preferred strategy (noted above), is accomplished by more extensive cleanup of the flue gas stream. Task 5--Process Engineering Model--We developed a process-engineering model for two purposes. The first was to predict the physical and chemical status at each test point in the design as a basis for scale-up. The second was to model the capital and operating cost of the apparatus. These were accomplished and used to predict capex, opex and cost of energy. Task 6--Preliminary Commercialization Plan--We carried out analyses of the market and the competition by a variety of parameters. The conclusion was that there is a l

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

Science Journals Connector (OSTI)

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

Trace gases, CO2, climate, and the greenhouse effect  

Science Journals Connector (OSTI)

Weather is driven by the sun’s energy input and the difference between insolation per unit area of the poles and the equator. The energy flux of the Earth is in long?term balance—as much is radiated away by the Earth as is absorbed or the mean temperature would have to increase or decrease steadily (and of course this is not observed). CO2 and other ‘‘trace gases’’ can cause the Earth’s mean temperature to rise through the Greenhouse Effect. The mean temperature in the Little Ice Age was only 1?°C cooler but large effects were felt especially toward the poles. The CO2 which stays in the atmosphere will raise Earth’s mean temperature with effects which are relatively certain: a lot of warming at the poles and a very small amount of warming at the equator.

Ultra-Low NOx Advanced Vortex Combustor  

SciTech Connect

An ultra lean-premixed Advanced Vortex Combustor (AVC) has been developed and tested. The natural gas fueled AVC was tested at the U.S. Department of Energy’s National Energy Technology Laboratory (USDOE NETL) test facility in Morgantown (WV). All testing was performed at elevated pressures and inlet temperatures and at lean fuel-air ratios representative of industrial gas turbines. The improved AVC design exhibited simultaneous NOx/CO/UHC emissions of 4/4/0 ppmv (all emissions are at 15% O2 dry). The design also achieved less than 3 ppmv NOx with combustion efficiencies in excess of 99.5%. The design demonstrated tremendous acoustic dynamic stability over a wide range of operating conditions which potentially makes this approach significantly more attractive than other lean premixed combustion approaches. In addition, a pressure drop of 1.75% was measured which is significantly lower than conventional gas turbine combustors. Potentially, this lower pressure drop characteristic of the AVC concept translates into overall gas turbine cycle efficiency improvements of up to one full percentage point. The relatively high velocities and low pressure drops achievable with this technology make the AVC approach an attractive alternative for syngas fuel applications.

This quarterly technical progress report will summarize work accomplished for the Program in the seventh quarter October-December 2001 in the following task areas: Task 1 - Oxygen Enhanced Combustion, Task 2 - Oxygen Transport Membranes, Task 3 - Economic Evaluation and Task 4 - Program Management. Computational fluid dynamic (CFD) modeling of oxygen injection strategies was performed during the quarter resulting in data that suggest the oxygen injection reduces NOx emissions while reducing LOI. Pilot-scale testing activities concluded at the University of Utah this quarter. Testing demonstrated that some experimental conditions can lead to NOx emissions well below the 0.15 lb/MMBtu limit. Evaluation of alternative OTM materials with improved mechanical properties continued this quarter. Powder procedure optimization continued and sintering trial began on an element with a new design. Several OTM elements were tested in Praxair's single tube high-pressure test facility under various conditions. A modified PSO1d element demonstrated stable oxygen product purity of >98% and oxygen flux of 68% of target. Updated test results and projected economic performance have been reviewed with the Utility Industrial Advisors. The economic comparison remains very favorable for O{sub 2} enhanced combustion. Discussions regarding possible Beta sites have been held with three other utilities in addition to the industrial advisors. Proposals will be prepared after the completion of full scale burner testing. Beta test cost estimating work has been initiated.

Separation of CO2 from flue gas using electrochemical cells  

SciTech Connect

ABSTRACT Past research with high temperature molten carbonate electrochemical cells has shown that carbon dioxide can be separated from flue gas streams produced by pulverized coal combustion for power generation, However, the presence of trace contaminants, i.e" sulfur dioxide and nitric oxides, will impact the electrolyte within the cell. If a lower temperature cell could be devised that would utilize the benefits of commercially-available, upstream desulfurization and denitrification in the power plant, then this CO2 separation technique can approach more viability in the carbon sequestration area, Recent work has led to the assembly and successful operation of a low temperature electrochemical cell. In the proof-of-concept testing with this cell, an anion exchange membrane was sandwiched between gas-diffusion electrodes consisting of nickel-based anode electrocatalysts on carbon paper. When a potential was applied across the cell and a mixture of oxygen and carbon dioxide was flowed over the wetted electrolyte on the cathode side, a stream of CO2 to O2 was produced on the anode side, suggesting that carbonate/ bicarbonate ions are the CO2 carrier in the membrane. Since a mixture of CO 2 and 02 is produced, the possibility exists to use this stream in oxy-firing of additional fuel. From this research, a novel concept for efficiently producing a carbon dioxide rich effiuent from combustion of a fossil fuel was proposed. Carbon dioxide and oxygen are captured from the flue gas of a fossilfuel combustor by one or more electrochemical cells or cell stacks. The separated stream is then transferred to an oxy-fired combustor which uses the gas stream for ancillary combustion, ultimately resulting in an effluent rich in carbon dioxide, A portion of the resulting flow produced by the oxy-fired combustor may be continuously recycled back into the oxy-fired combustor for temperature control and an optimal carbon dioxide rich effluent.

Efficient parallel simulation of CO2 geologic sequestration insaline aquifers  

SciTech Connect

An efficient parallel simulator for large-scale, long-termCO2 geologic sequestration in saline aquifers has been developed. Theparallel simulator is a three-dimensional, fully implicit model thatsolves large, sparse linear systems arising from discretization of thepartial differential equations for mass and energy balance in porous andfractured media. The simulator is based on the ECO2N module of the TOUGH2code and inherits all the process capabilities of the single-CPU TOUGH2code, including a comprehensive description of the thermodynamics andthermophysical properties of H2O-NaCl- CO2 mixtures, modeling singleand/or two-phase isothermal or non-isothermal flow processes, two-phasemixtures, fluid phases appearing or disappearing, as well as saltprecipitation or dissolution. The new parallel simulator uses MPI forparallel implementation, the METIS software package for simulation domainpartitioning, and the iterative parallel linear solver package Aztec forsolving linear equations by multiple processors. In addition, theparallel simulator has been implemented with an efficient communicationscheme. Test examples show that a linear or super-linear speedup can beobtained on Linux clusters as well as on supercomputers. Because of thesignificant improvement in both simulation time and memory requirement,the new simulator provides a powerful tool for tackling larger scale andmore complex problems than can be solved by single-CPU codes. Ahigh-resolution simulation example is presented that models buoyantconvection, induced by a small increase in brine density caused bydissolution of CO2.

CO2 adsorption capacity of argonne premium coals  

Science Journals Connector (OSTI)

Adsorption and desorption isotherms of CO2 on dried Argonne Premium coal samples were investigated. A small hysteresis was detected between the adsorption and desorption isotherms. The hysteresis was small or negligible for high rank coals but discernable for low rank coals. The isotherms were found to be rectilinear and to fit the conventional adsorption equations poorly. The rectilinear shape of the adsorption isotherms was related to the solubility of the CO2 in the coal and to coal swelling. Using an adsorption model that accounted for volumetric effects provided good agreement between the surface areas calculated from the high-pressure isotherms and the literature values obtained under traditional low-pressure conditions. Ignoring the volumetric effects resulted in estimated surface areas that were 40% larger for the higher-ranked coals and 60–100% larger for the lower-ranked coals. The heat of adsorption, after correcting for volumetric effects, was fairly constant (26±1 kJ/mol) regardless of rank. The adsorption capacity, average pore size, and volume effect for each of the Argonne coals were also estimated employing the same model. The model equation explicitly accounts for volumetric effects, attributable to the solubility of CO2 in the organic matrix and the coal swelling, and estimates the actual adsorbed amount.

Recycled CO2 will be used in this demonstration project to produce bypassed oil from the Silurian Dover 35 pinnacle reef (Otsego County) in the Michigan Basin. Contract negotiations by our industry partner to gain access to the CO2 supply have been completed and the State of Michigan has issued an order to allow operation of the project. Injection of CO2 is scheduled to begin in February, 2004. Subsurface characterization is being completed using well log tomography animations and 3D visualizations to map facies distributions and reservoir properties in two reefs, the Belle River Mills and Chester 18 Fields. The Belle River Mills and Chester18 fields are being used as type-fields because they have excellent log and/or core data coverage. Amplitude slicing of the normalized gamma ray and core permeability and core porosity curves is showing trends that indicate significant heterogeneity and compartmentalization in these reservoirs associated with the original depositional fabric of the rocks. Digital and hard copy data continues to be compiled for the Niagaran reefs in the Michigan Basin. Technology transfer took place through technical presentations regarding visualization of the heterogeneity of the Niagaran reefs. An oral presentation was given at the AAPG Eastern Section Meeting and a booth at the same meeting was used to meet one-on-one with operators.

Wellbores that no longer provide proper zonal isolation establish a primary pathway for a buoyant CO2-rich phase to escape from the intended storage formation. The hazard of CO2 leakage along these pathways will depend on the rate of leakage. Thus a useful component of a risk assessment framework is a model of CO2 leakage.

Gulf of Mexico Miocene CO2 Site Characterization Mega Transect  

SciTech Connect

This project characterized the Miocene-age sub-seafloor stratigraphy in the near-offshore portion of the Gulf of Mexico adjacent to the Texas coast. The large number of industrial sources of carbon dioxide (CO2) in coastal counties and the high density of onshore urbanization and environmentally sensitive areas make this offshore region extremely attractive for long-term storage of carbon dioxide emissions from industrial sources (CCS). The study leverages dense existing geologic data from decades of hydrocarbon exploration in and around the study area to characterize the regional geology for suitability and storage capacity. Primary products of the study include: regional static storage capacity estimates, sequestration “leads” and prospects with associated dynamic capacity estimates, experimental studies of CO2-brine-rock interaction, best practices for site characterization, a large-format ‘Atlas’ of sequestration for the study area, and characterization of potential fluid migration pathways for reducing storage risks utilizing novel high-resolution 3D (HR3D) seismic surveys. In addition, three subcontracted studies address source-to-sink matching optimization, offshore well bore management and environmental aspects. The various geologic data and interpretations are integrated and summarized in a series of cross-sections and maps, which represent a primary resource for any near-term commercial deployment of CCS in the area. The regional study characterized and mapped important geologic features (e.g., Clemente-Tomas fault zone, the regionally extensive Marginulina A and Amphistegina B confining systems, etc.) that provided an important context for regional static capacity estimates and specific sequestration prospects of the study. A static capacity estimate of the majority of the Study area (14,467 mi2) was estimated at 86 metric Gigatonnes. While local capacity estimates are likely to be lower due to reservoir-scale characteristics, the offshore Miocene interval is a storage resource of National interest for providing CO2 storage as an atmospheric emissions abatement strategy. The natural petroleum system was used as an analog to infer seal quality and predict possible migration pathways of fluids in an engineered system of anthropogenic CO2 injection and storage. The regional structural features (e.g., Clemente-Tomas fault zone) that exert primary control on the trapping and distribution of Miocene hydrocarbons are expected to perform similarly for CCS. Industrial?scale CCS will require storage capacity utilizing well?documented Miocene hydrocarbon (dominantly depleted gas) fields and their larger structural closures, as well as barren (unproductive, brine?filled) closures. No assessment was made of potential for CO2 utilization for enhanced oil and gas recovery. The use of 3D numerical fluid flow simulations have been used in the study to greatly assist in characterizing the potential storage capacity of a specific reservoir. Due to the complexity of geologic systems (stratigraphic heterogeneity) and inherent limitations on producing a 3D geologic model, these simulations are typically simplified scenarios that explore the influence of model property variability (sensitivity study). A specific site offshore San Luis Pass (southern Galveston Island) was undertaken successfully, indicating stacked storage potential. Downscaling regional capacity estimates to the local scale (and the inverse) has proven challenging, and remains an outstanding gap in capacity assessments. In order to characterize regional seal performance and identify potential brine and CO2 leakage pathways, results from three high-resolution 3D (HR3D) seismic datasets acquired by the study using novel HR3D (P-Cable) acquisition system showed steady and significant improvements in data quality because of improved acquisition and processing technique. Finely detailed faults and stratigraphy in the shallowest 1000 milliseconds (~800 m) of data allowed for the identification and mapping of unconformable surfaces including what is probably

Quantification of fossil fuel CO2 emissions at the building/street scale for a large US city  

SciTech Connect

In order to advance the scientific understanding of carbon exchange with the land surface, build an effective carbon monitoring system and contribute to quantitatively-based U.S. climate change policy interests, fine spatial and temporal quantification of fossil fuel CO2 emissions, the primary greenhouse gas, is essential. Called the ‘Hestia Project’, this research effort is the first to use bottom-up methods to quantify all fossil fuel CO2 emissions down to the scale of individual buildings, road segments, and industrial/electricity production facilities on an hourly basis for an entire urban landscape. a large city (Indianapolis, Indiana USA). Here, we describe the methods used to quantify the on-site fossil fuel CO2 emissions across the city of Indianapolis, Indiana. This effort combines a series of datasets and simulation tools such as a building energy simulation model, traffic data, power production reporting and local air pollution reporting. The system is general enough to be applied to any large U.S. city and holds tremendous potential as a key component of a carbon monitoring system in addition to enabling efficient greenhouse gas mitigation and planning. We compare our estimate of fossil fuel emissions from natural gas to consumption data provided by the local gas utility. At the zip code level, we achieve a bias adjusted pearson r correlation value of 0.92 (p<0.001).

IMPLEMENTING A NOVEL CYCLIC CO2 FLOOD IN PALEOZOIC REEFS  

SciTech Connect

Recycled CO2 will be used in this demonstration project to produce bypassed oil from the Silurian Charlton 6 pinnacle reef (Otsego County) in the Michigan Basin. Contract negotiations by our industry partner to gain access to this CO2 that would otherwise be vented to the atmosphere are near completion. A new method of subsurface characterization, log curve amplitude slicing, is being used to map facies distributions and reservoir properties in two reefs, the Belle River Mills and Chester 18 Fields. The Belle River Mills and Chester18 fields are being used as typefields because they have excellent log-curve and core data coverage. Amplitude slicing of the normalized gamma ray curves is showing trends that may indicate significant heterogeneity and compartmentalization in these reservoirs. Digital and hard copy data continues to be compiled for the Niagaran reefs in the Michigan Basin. Technology transfer took place through technical presentations regarding the log curve amplitude slicing technique and a booth at the Midwest PTTC meeting.

Recycled CO2 will be used in this demonstration project to produce bypassed oil from the Silurian Dover 35 pinnacle reef (Otsego County) in the Michigan Basin. We began injecting CO2 in the Dover 35 field into the Salling-Hansen 4-35A well on May 6, 2004. Subsurface characterization is being completed using well log tomography animations and 3D visualizations to map facies distributions and reservoir properties in three reefs, the Belle River Mills, Chester 18, and Dover 35 Fields. The Belle River Mills and Chester 18 fields are being used as type-fields because they have excellent log and/or core data coverage. Amplitude slicing of the log porosity, normalized gamma ray, core permeability, and core porosity curves is showing trends that indicate significant heterogeneity and compartmentalization in these reservoirs associated with the original depositional fabric of the rocks. Digital and hard copy data continues to be compiled for the Niagaran reefs in the Michigan Basin. Technology transfer took place through technical presentations regarding visualization of the heterogeneity of the Niagaran reefs. Oral presentations were given at the Petroleum Technology Transfer Council workshop, Michigan Oil and Gas Association Conference, and Michigan Basin Geological Society meeting. A technical paper was submitted to the Bulletin of the American Association of Petroleum Geologists on the characterization of the Belle River Mills Field.

IMPLEMENTING A NOVEL CYCLIC CO2 FLOOD IN PALEOZOIC REEFS  

SciTech Connect

Recycled CO2 is being used in this demonstration project to produce bypassed oil from the Silurian Dover 35 Niagaran pinnacle reef located in Otsego County, Michigan. CO2 injection in the Dover 35 field into the Salling-Hansen 4-35A well began on May 6, 2004. A second injection well, the Salling-Hansen 1-35, commenced injection in August 2004. Oil production in the Pomerzynski 5-35 producing well increased from 9 BOPD prior to operations to an average of 165 BOPD in December, 2004 and has produced at an average rate of 61 BOPD (Jan-Dec, 2005). The Salling-Hansen 4-35A also produced during this reporting period an average of 29 BOPD. These increases have occurred as a result of CO2 injection and the production rate appears to be stabilizing. CO2 injection volume has reached approximately 2.18 BCF. The CO2 injection phase of this project has been fully operational since December 2004 and most downhole mechanical issues have been solved and surface facility modifications have been completed. It is anticipated that filling operations will run for another 6-12 months from July 1, 2005. In most other aspects, the demonstration is going well and hydrocarbon production has been stabilized at an average rate of 57 BOPD (July-Dec, 2005). Our industry partners continue to experiment with injection rates and pressures, various downhole and surface facility mechanical configurations, and the huff-n-puff technique to develop best practices for these types of enhanced recovery projects. Subsurface characterization was completed using well log tomography and 3D visualizations to map facies distributions and reservoir properties in the Belle River Mills, Chester 18, Dover 35, and Dover 36 Fields. The Belle River Mills and Chester 18 fields are being used as type-fields because they have excellent log and/or core data coverage. Amplitude slicing of the log porosity, normalized gamma ray, core permeability, and core porosity curves are showing trends that indicate significant heterogeneity and compartmentalization in these reservoirs associated with the original depositional fabric and pore types of the carbonate reservoir rocks. Accumulated pressure data supports the hypothesis of extreme heterogeneity in the Dover 35. Some intervals now have pressure readings over 2345 psig (April 29, 2005) in the A-1 Carbonate while nearby Niagaran Brown intervals only show 1030 psig (March 7, 2005). This is a pressure differential over 1300 psig and suggests significant vertical barriers in the reef, consistent with the GR tomography modeling. Digital and hard copy data have been compiled for the Niagaran reefs in the Michigan Basin, including a detailed summary of 20 fields in the vicinity of the demonstration well. Technology transfer took place through technical presentations regarding visualization of the reservoir heterogeneity in these Niagaran reefs. Oral presentations were given at two Petroleum Technology Transfer Council workshops, a Michigan Oil and Gas Association Conference, a Michigan Basin Geological Society meeting, and the Eastern American Association of Petroleum Geologist's Annual meeting. In addition, we met with our industry partners several times during the first half of 2005 to communicate and discuss the reservoir characterization and field site aspects of the demonstration project. A technical paper was published in the April 2005 issue of the AAPG Bulletin on the characterization of the Belle River Mills Field.

Brucite [Mg(OH2)] carbonation in wet supercritical CO2: An in situ high pressure X-ray diffraction study  

Science Journals Connector (OSTI)

Understanding mechanisms and kinetics of mineral carbonation reactions relevant to sequestering carbon dioxide as a supercritical fluid (scCO2) in geologic formations is crucial to accurately predicting long-term storage risks. Most attention so far has been focused on reactions occurring between silicate minerals and rocks in the aqueous dominated CO2-bearing fluid. However, water-bearing scCO2 also comprises a reactive fluid, and in this situation mineral carbonation mechanisms are poorly understood. Using in situ high-pressure X-ray diffraction, the carbonation of brucite [Mg(OH)2] in wet scCO2 was examined at pressure (82 bar) as a function of water concentration and temperature (50 and 75 °C). Exposing brucite to anhydrous scCO2 at either temperature resulted in little or no detectable reaction over three days. However, addition of trace amounts of water resulted in partial carbonation of brucite into nesquehonite [MgCO3·3H2O] within a few hours at 50 °C. By increasing water content to well above the saturation level of the scCO2, complete conversion of brucite into nesquehonite was observed. Tests conducted at 75 °C resulted in the conversion of brucite into magnesite [MgCO3] instead, apparently through an intermediate nesquehonite step. Raman spectroscopy applied to brucite reacted with 18O-labeled water in scCO2 show it was incorporated into carbonate at a relatively high concentration. This supports a carbonation mechanism with at least one step involving a direct reaction between the mineral and water molecules without mediation by a condensed aqueous layer.

Chemical Looping for Pre-combustion CO2 Capture — Performance and Cost Analysis  

Science Journals Connector (OSTI)

Abstract The objective of this paper is to compare the two technologies chemical looping combustion (CLC) for inherent CO2-capture, and Calcium looping-based (CaL) CO2-capture when applied to a coal-based IGCC power plant, in terms of system efficiency, overall plant efficiency, CO2-capture percentage and cost. It was found that a CLC-based CO2 capture system is more efficient than a CaL-based CO2 capture system. However, both the chemical looping processes lead to higher efficiencies than a conventional solvent-based pre-combustion CO2 capture. The capital cost and cost of electricity of the CLC-based CO2- capture power plant were also found to be lower than a conventional pre-combustion CO2-capture for an IGCC power plant.

Lean Gasoline Engine Reductant Chemistry During Lean NOx Trap Regeneration  

SciTech Connect

Lean NOx Trap (LNT) catalysts can effectively reduce NOx from lean engine exhaust. Significant research for LNTs in diesel engine applications has been performed and has led to commercialization of the technology. For lean gasoline engine applications, advanced direct injection engines have led to a renewed interest in the potential for lean gasoline vehicles and, thereby, a renewed demand for lean NOx control. To understand the gasoline-based reductant chemistry during regeneration, a BMW lean gasoline vehicle has been studied on a chassis dynamometer. Exhaust samples were collected and analyzed for key reductant species such as H2, CO, NH3, and hydrocarbons during transient drive cycles. The relation of the reductant species to LNT performance will be discussed. Furthermore, the challenges of NOx storage in the lean gasoline application are reviewed.

Assessment of CO2 capture options from various points in steam methane reforming for hydrogen production  

Science Journals Connector (OSTI)

Abstract Steam methane reforming (SMR) is currently the main hydrogen production process in industry, but it has high emissions of CO2, at almost 7 kg CO2/kg H2 on average, and is responsible for about 3% of global industrial sector CO2 emissions. Here, the results are reported of an investigation of the effect of steam-to-carbon ratio (S/C) on CO2 capture criteria from various locations in the process, i.e. synthesis gas stream (location 1), pressure swing adsorber (PSA) tail gas (location 2), and furnace flue gases (location 3). The CO2 capture criteria considered in this study are CO2 partial pressure, CO2 concentration, and CO2 mass ratio compared to the final exhaust stream, which is furnace flue gases. The CO2 capture number (Ncc) is proposed as measure of capture favourability, defined as the product of the three above capture criteria. A weighting of unity is used for each criterion. The best S/C ratio, in terms of providing better capture option, is determined. CO2 removal from synthesis gas after the shift unit is found to be the best location for CO2 capture due to its high partial pressure of CO2. However, furnace flue gases, containing almost 50% of the CO2 in produced in the process, are of great significance environmentally. Consequently, the effects of oxygen enrichment of the furnace feed are investigated, and it is found that this measure improves the CO2 capture conditions for lower S/C ratios. Consequently, for an S/C ratio of 2.5, CO2 capture from a flue gas stream is competitive with two other locations provided higher weighting factors are considered for the full presence of CO2 in the flue gases stream. Considering carbon removal from flue gases, the ratio of hydrogen production rate and Ncc increases with rising reformer temperature.
