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.

Spatial Relationships of Sector-Specific Fossil-fuel CO2 Emissions in the United States  

SciTech Connect

Quantification of the spatial distribution of sector-specific fossil fuel CO2 emissions provides strategic information to public and private decision-makers on climate change mitigation options and can provide critical constraints to carbon budget studies being performed at the national to urban scales. This study analyzes the spatial distribution and spatial drivers of total and sectoral fossil fuel CO2 emissions at the state and county levels in the United States. The spatial patterns of absolute versus per capita fossil fuel CO2 emissions differ substantially and these differences are sector-specific. Area-based sources such as those in the residential and commercial sectors are driven by a combination of population and surface temperature with per capita emissions largest in the northern latitudes and continental interior. Emission sources associated with large individual manufacturing or electricity producing facilities are heterogeneously distributed in both absolute and per capita metrics. The relationship between surface temperature and sectoral emissions suggests that the increased electricity consumption due to space cooling requirements under a warmer climate may outweigh the savings generated by lessened space heating. Spatial cluster analysis of fossil fuel CO2 emissions confirms that counties with high (low) CO2 emissions tend to be clustered close to other counties with high (low) CO2 emissions and some of the spatial clustering extends to multi-state spatial domains. This is particularly true for the residential and transportation sectors, suggesting that emissions mitigation policy might best be approached from the regional or multi-state perspective. Our findings underscore the potential for geographically focused, sector-specific emissions mitigation strategies and the importance of accurate spatial distribution of emitting sources when combined with atmospheric monitoring via aircraft, satellite and in situ measurements.

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

Science Journals Connector (OSTI)

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

Techno-economic evaluation of using biomass-fired auxiliary units for supplying energy requirements of CO2 capture in coal-fired power plants  

Science Journals Connector (OSTI)

Abstract Parasitically providing the energy required for CO2 capture from retrofitted coal power plants can lead to a significant loss in output of electricity. In this study, different configurations of auxiliary units are investigated to partially or totally meet the energy requirements for MEA post-combustion capture in a 500MW sub-critical coal-fired plant. The auxiliary unit is either a boiler, providing only the heat required for solvent regeneration in the capture process or a combined heat and power (CHP) unit, providing both heat and electricity. Using biomass in auxiliary units, the grid loss is reduced without increasing fossil fuel consumption. The results show that using a biomass CHP unit is more favourable than using a biomass boiler both in terms of CO2 emission reductions and power plant economic viability. By using an auxiliary biomass CHP unit, both the emission intensity and the cost of electricity would be marginally lower than for a coal plant with capture. Further emission reductions occur if CO2 is captured both from the coal plant and the auxiliary biomass CHP, resulting in negative emissions. However, high incentive schemes (a carbon price higher than 55 $/t CO2 or a combination of lower carbon price and renewable energy certificates) or a low biomass price (lower than 1 $/GJ) are required to make CO2 capture from both the coal plant and the auxiliary biomass CHP unit economically attractive. All cost comparisons are for CO2 capture only and CO2 transport and storage are not included in this study.

Optimal control system design of an acid gas removal unit for an IGCC power plants with CO2 capture  

SciTech Connect

Future IGCC plants with CO{sub 2} capture should be operated optimally in the face of disturbances without violating operational and environmental constraints. To achieve this goal, a systematic approach is taken in this work to design the control system of a selective, dual-stage Selexol-based acid gas removal (AGR) unit for a commercial-scale integrated gasification combined cycle (IGCC) power plant with pre-combustion CO{sub 2} capture. The control system design is performed in two stages with the objective of minimizing the auxiliary power while satisfying operational and environmental constraints in the presence of measured and unmeasured disturbances. In the first stage of the control system design, a top-down analysis is used to analyze degrees of freedom, define an operational objective, identify important disturbances and operational/environmental constraints, and select the control variables. With the degrees of freedom, the process is optimized with relation to the operational objective at nominal operation as well as under the disturbances identified. Operational and environmental constraints active at all operations are chosen as control variables. From the results of the optimization studies, self-optimizing control variables are identified for further examination. Several methods are explored in this work for the selection of these self-optimizing control variables. Modifications made to the existing methods will be discussed in this presentation. Due to the very large number of candidate sets available for control variables and due to the complexity of the underlying optimization problem, solution of this problem is computationally expensive. For reducing the computation time, parallel computing is performed using the Distributed Computing Server (DCS) and the Parallel Computing toolbox from Mathworks. The second stage is a bottom-up design of the control layers used for the operation of the process. First, the regulatory control layer is designed followed by the supervisory control layer. Finally, an optimization layer is designed. In this paper, the proposed two-stage control system design approach is applied to the AGR unit for an IGCC power plant with CO{sub 2} capture. Aspen Plus Dynamics is used to develop the dynamic AGR process model while MATLAB is used to perform the control system design and for implementation of model predictive control (MPC).

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.

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 30,000m3. 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 (?50C, 7bar) and (?30C, 15bar). The ship has an autonomy of 6 days, is able to cover 1000km with a cargo of 2.5Mt/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 350km and with an onshore pipeline when it exceeds 1100km.

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

Sensor placement algorithm development to maximize the efficiency of acid gas removal unit for integrated gasifiction combined sycle (IGCC) power plant with CO2 capture  

SciTech Connect

Future integrated gasification combined cycle (IGCC) power plants with CO{sub 2} capture will face stricter operational and environmental constraints. Accurate values of relevant states/outputs/disturbances are needed to satisfy these constraints and to maximize the operational efficiency. Unfortunately, a number of these process variables cannot be measured while a number of them can be measured, but have low precision, reliability, or signal-to-noise ratio. In this work, a sensor placement (SP) algorithm is developed for optimal selection of sensor location, number, and type that can maximize the plant efficiency and result in a desired precision of the relevant measured/unmeasured states. In this work, an SP algorithm is developed for an selective, dual-stage Selexol-based acid gas removal (AGR) unit for an IGCC plant with pre-combustion CO{sub 2} capture. A comprehensive nonlinear dynamic model of the AGR unit is developed in Aspen Plus Dynamics (APD) and used to generate a linear state-space model that is used in the SP algorithm. The SP algorithm is developed with the assumption that an optimal Kalman filter will be implemented in the plant for state and disturbance estimation. The algorithm is developed assuming steady-state Kalman filtering and steady-state operation of the plant. The control system is considered to operate based on the estimated states and thereby, captures the effects of the SP algorithm on the overall plant efficiency. The optimization problem is solved by Genetic Algorithm (GA) considering both linear and nonlinear equality and inequality constraints. Due to the very large number of candidate sets available for sensor placement and because of the long time that it takes to solve the constrained optimization problem that includes more than 1000 states, solution of this problem is computationally expensive. For reducing the computation time, parallel computing is performed using the Distributed Computing Server (DCS) and the Parallel Computing toolbox from Mathworks. In this presentation, we will share our experience in setting up parallel computing using GA in the MATLAB environment and present the overall approach for achieving higher computational efficiency in this framework.

Oceania » Japan Oceania » Japan Japan Fossil-Fuel CO2 Emissions Graph graphic Graphics Data graphic Data Trends The history of fossil-fuel CO2 emissions from Japan is remarkable for the abrupt change that occurred in 1973. With postwar growth at 9.8% per year from 1950 to 1973, total emissions were virtually constant from 1974-1987. From 1987-96, emissions grew 25.3% reaching 329 million metric tons of carbon. Growth during this period was characterized by a return to mid-1970s consumption levels for liquid petroleum products and increased contributions from coal and natural gas use. Since 1996, Japan's fossil-fuel CO2 emissions have vacilated and now total 329 million metric tons of carbon in 2008.

SciTech Connect

The primary goal of this project was to demonstrate a new and novel approach for high resolution, 3D reservoir characterization that can enable better management of CO{sub 2} enhanced oil recovery (EOR) projects and, looking to the future, carbon sequestration projects. The approach adopted has been the subject of previous research by the DOE and others, and relies primarily upon data-mining and advanced pattern recognition approaches. This approach honors all reservoir characterization data collected, but accepts that our understanding of how these measurements relate to the information of most interest, such as how porosity and permeability vary over a reservoir volume, is imperfect. Ideally the data needed for such an approach includes surface seismic to provide the greatest amount of data over the entire reservoir volume of interest, crosswell seismic to fill the resolution gap between surface seismic and wellbore-scale measurements, geophysical well logs to provide the vertical resolution sought, and core data to provide the tie to the information of most interest. These data are combined via a series of one or more relational models to enable, in its most successful application, the prediction of porosity and permeability on a vertical resolution similar to logs at each surface seismic trace location. In this project, the procedure was applied to the giant (and highly complex) SACROC unit of the Permian basin in West Texas, one of the world's largest CO{sub 2}-EOR projects and a potentially world-class geologic sequestration site. Due to operational scheduling considerations on the part of the operator of the field, the crosswell data was not obtained during the period of project performance (it is currently being collected however as part of another DOE project). This compromised the utility of the surface seismic data for the project due to the resolution gap between it and the geophysical well logs. An alternative approach was adopted that utilized a relational model to predict porosity and permeability profiles from well logs at each well location, and a 3D geostatistical variogram to generate the reservoir characterization over the reservoir volume of interest. A reservoir simulation model was built based upon this characterization and history-matched without making significant changes to it, thus validating the procedure. While not the same procedure as originally planned, the procedure ultimately employed proved successful and demonstrated that the general concepts proposed (i.e., data mining and advanced pattern recognition methods) have the flexibility to achieve the reservoir characterization objectives sought even with imperfect or incomplete data.

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.

Uncertainty quantification for CO2 sequestration and enhanced oil recovery  

E-Print Network (OSTI)

This study develops a statistical method to perform uncertainty quantification for understanding CO2 storage potential within an enhanced oil recovery (EOR) environment at the Farnsworth Unit of the Anadarko Basin in northern Texas. 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...

CO2 Sequestration short course  

SciTech Connect

Given the publics 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).

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.

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.

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%.

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.

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 7kg 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.

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.

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.

Techno-economic assessment of CO2 capture at steam methane reforming facilities using commercially available technology  

Science Journals Connector (OSTI)

This study aimed to identify the optimal techno-economic configuration of CO2 capture at steam methane reforming facilities using currently available technologies by means of process simulations. Results indicate that the optimal system is CO2 capture with ADIP-X located between the watergas shift and pressure swing adsorption units. Process simulations of this system configuration showed a CO2 emission reduction of 60% at 41/t CO2 avoidance. This is at the lower end of the range reported in open literature for CO2 capture at refineries (2682/t CO2) and below the avoidance costs for CO2 capture at natural gas-fired power plants (4493/t CO2). CO2 avoidance costs are dominated by the natural gas consumption, responsible for up to 66% of total costs. Using imported steam and electricity can reduce CO2 avoidance costs by 45%. Addition of small amounts of piperazine to aqueous MDEA solutions results in up to 70% smaller absorbers or 10% lower reboiler heat duty. Optimising the whole capture process instead of individual units resulted in lower piperazine concentrations than the common industrial practice (3mass% vs. 5mass%). Finally, keeping the solvent rate constant when operating the capture unit below its design load resulted in a lower specific energy for CO2 capture than when the solvent rate was downscaled with the syngas flow.

Trace gases, CO2, climate, and the greenhouse effect  

Science Journals Connector (OSTI)

Weather is driven by the suns 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 balanceas 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 Earths 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 Earths 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.

Poland Fossil-Fuel CO2 Emissions  

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

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

Windowed Carbon Nanotubes for Efficient CO2 Removal from Natural Gas  

E-Print Network (OSTI)

We demonstrate from molecular dynamics simulations that windowed carbon nanotubes can efficiently separate CO2 from the CO2/CH4 mixture, resembling polymeric hollow fibers for gas separation. Three CO2/CH4 mixtures with 30%, 50% and 80% CO2 are investigated as a function of applied pressure from 80 to 180 bar. In all simulated conditions, only CO2 permeation is observed; CH4 is completely rejected by the nitrogen-functionalized windows or pores on the nanotube wall in the accessible timescale, while maintaining a fast diffusion rate along the tube. The estimated time-dependent CO2 permeance ranges from 107 to 105 GPU (gas permeation unit), compared with ~100 GPU for typical polymeric membranes. CO2/CH4 selectivity is estimated to be ~108 from the difference in free-energy barriers of permeation. This work suggests that a windowed carbon nanotube can be used as a highly efficient medium, configurable in hollow-fiber-like modules, for removing CO2 from natural gas.

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 700C 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 650C 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.

Geological Sequestration of CO2 by Hydrous Carbonate Formation with Reclaimed Slag  

SciTech Connect

The concept of this project is to develop a process that improves the kinetics of the hydrous carbonate formation reaction enabling steelmakers to directly remove CO2 from their furnace exhaust gas. It is proposed to bring the furnace exhaust stream containing CO2 in contact with reclaimed steelmaking slag in a reactor that has an environment near the unit activity of water resulting in the production of carbonates. The CO2 emissions from the plant would be reduced by the amount sequestered in the formation of carbonates. The main raw materials for the process are furnace exhaust gases and specially prepared slag.

Mitigating CO2 emissions by adjusting the power generation mix in Taiwan  

Science Journals Connector (OSTI)

In this paper, we employ a multi-objective programming model to estimate the power generation mix trade-off between generation costs and CO2 emissions in Taiwan. Eight policy scenarios are simulated and compared to the reference and base cases. The empirical results show that, for the electricity sector, CO2 emissions in 2010 could be set at 120% of the 1990 level, by way of promoting cogeneration and gas-fired generation capacity. The estimated per unit mitigation cost of CO2 emission would be US$358/ton. The policy implications are discussed and limitation of this study is also presented.

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 yr1) of new coal generating capacity was added between 2010 and 2012, 23 GW yr1 more than in the 20002009 time period and 56 GW yr1 more than in the 19901999 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 192439) 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 ?

Regenerable MgO-based sorbent for high temperature CO2 removal from syngas: 3. CO2 capture and sorbent enhanced water gas shift reaction  

Science Journals Connector (OSTI)

Abstract Regenerable MgO-based sorbent, which was prepared and evaluated in the thermogravimetric analyzer (TGA) in part 1, was also evaluated in high-pressure packed-bed unit in CO2/N2/H2O mixture and simulated pre-combustion syngas environment. In CO2/N2/H2O environment, the CO2 absorption capacity of the sorbent increases with increasing temperatures from 6.7% at 350C to 9.5% 450C. The sorbent is capable of achieving over 95% CO2 capture and 40% conversion in the water gas shift (WGS) reaction, which should be attributed to positive effect of WGS reaction in producing CO2 during the process. The sorbent reactivity and absorption capacity toward CO2, as well as its WGS catalytic activity decreases with increasing temperature. The maximum pre-breakthrough WGS conversion occurs at 350C, which diminishes as the sorbent is carbonated. The variable diffusivity shrinking core reaction model coupled with the two-fluid computational fluid dynamics (CFD) model was shown to accurately predict the break-through gas compositions at different operating conditions.

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.

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

Solid Sorbents as a Retrofit Technology for CO2 Capture Solid Sorbents as a Retrofit Technology for CO2 Capture Project No.: DE-FE0004343 ADA-ES Inc. is refining the conceptual design of a commercial solid sorbent-based, post-combustion CO2 capture technology through slipstream pilot testing and process modeling. A pilot unit (~1 MW) will be designed and constructed to demonstrate solid sorbent-based CO2 capture on actual flue gas. The pilot tests and process modeling will provide the information necessary to complete a techno-economic analysis of the technology. The design will be based on a 1 kW-scale transport reactor system built and demonstrated under an existing DOE/NETL CO2 capture project (Figure). There are several advantages solids offer over aqueous MEA. For example, solids have a working capacity over two times that of MEA, by weight, leading to lower regeneration energy attributable to less material to heat. The increased capacity, in conjunction with the lower heat capacity, results in a theoretical regeneration energy approximately half that of MEA, per kg of CO2. This indicates that solids can dramatically reduce the energy requirements for CO2 capture compared to aqueous systems. In addition, circulating less material in a solid-based system compared to aqueous MEA will likely lead to lower pressure drop, depending on the system configuration. Also, solids have the potential to be less corrosive than the solution used in aqueous MEA systems.

Amorphous silicon films were deposited by a CO2 laser CVD (chemical vapor deposition) method using disilane gas. With this gas, the films were deposited reasonably fast at relatively low substrate temperatures of 350C or above. Unlike monosilane, photo-induced effects in the gas phase following light absorption were negligible in deposition processes, and only the pyrolytic process taking place at the laser-heated substrate was important. Some of the physical properties of deposited films were described.

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.

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.

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

An exergy based approach to determine production cost and CO2 allocation for petroleum derived fuels  

Science Journals Connector (OSTI)

Abstract The renewable and non-renewable exergy and CO2 costs of petroleum derived fuels produced in Brazil are evaluated using exergoeconomy to rationally distribute the exergy costs and the CO2 emitted in processes with more than one product. An iterative procedure is used to take into account the cyclic interactions of the processed fuels. The renewable and non-renewable exergy costs together with the CO2 cost provide a reasonable way to compare different fuels and can be used to assess an enormous quantity of processes that make use of petroleum derived products. The system considers Brazilian typical processes and distances: offshore oil and gas production, transportation by shuttle tankers and pipelines, and refining. It was observed that the renewable exergy cost contribution in the total exergy cost of petroleum derived fuels is negligible. On average, the refining process is responsible, for 85% of the total unit exergy cost. Total unit exergy costs of gasoline, liquefied petroleum gas, natural gas and fuel oil were found to be: 1.081MJ/MJ, 1.074MJ/MJ, 1.064MJ/MJ, 1.05MJ/MJ, respectively. The hydrotreatment process increases diesel cost from 1.038MJ/MJ to 1.11MJ/MJ in order to decrease its sulphur content. The CO2 cost reflects the extent of processing as well as the C/H ratio of the used fuel. Hence, coke followed by hydrotreated diesel have the largest CO2 cost among the fuels, 91gCO2/MJ and 79gCO2/MJ, respectively.

The effect of CO2 regulations on the cost of corn ethanol production  

Science Journals Connector (OSTI)

To explore the effect of CO2 price on the effective cost of ethanol production we have developed a model that integrates financial and emissions accounting for dry-mill corn ethanol plants. Three policy options are modeled: (1) a charge per unit of life cycle CO2 emissions, (2)a charge per unit of direct biorefinery emissions only, and (3) a low carbon fuel standard (LCFS). A CO2 charge on life cycle emissions increases production costs by between $0.005 and $0.008l?1 per $10Mg?1CO2 price increment, across all modeled plant energy systems, with increases under direct emissions somewhat lower in all cases. In contrast, a LCFS increases the cost of production for selected plant energy systems only: a LCFS requiring reductions in average fuel global warming intensity (GWI) with a target of 10% below the 2005 baseline increases the production costs for coal-fired plants only. For all other plant types, the LCFS operates as a subsidy. The findings depend strongly on the magnitude of a land use change adder. Some land use change adders currently discussed in the literature will push the GWI of all modeled production systems above the LCFS target, flipping the CO2 price from a subsidy to a tax.

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 100C.

Biomass combustion with CO2 capture by chemical looping with oxygen uncoupling (CLOU)  

Science Journals Connector (OSTI)

Abstract Economic benefits can be expected in the future if CO2 capture and storage are implemented in energy generation from biomass combustion. The aim of this work is to investigate the combustion of biomass in a chemical looping with oxygen uncoupling (CLOU) process with inherent CO2 separation. The performance of biomass combustion in a continuously operated 1.5kWth CLOU unit is presented. Particles prepared by spray drying containing 60wt.% CuO were used as an oxygen carrier. Milled pine wood chips were used as fuel. The work focused on the effect of fuel reactor temperature on the CO2 capture and the combustion efficiency of the CLOU process with biomass. Under CLOU operation, biomass combustion was complete to CO2 and H2O without the presence of any unburnt material, including tars. Moreover, high carbon capture efficiencies were achieved using very low oxygen carrier inventories and without a carbon separation unit. This is the first time that the CLOU concept has been demonstrated in a continuous CLC unit using biomass as fuel.

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 sorptiondesorption 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.

Energy intensities and CO2 emissions in Catalonia: a SAM analysis  

Science Journals Connector (OSTI)

In this paper, we estimate sectoral energy intensities and CO2 emissions for the Catalonian economy. In order to evaluate energy intensities, we use the SAM (Social Accounting Matrix) multiplier analysis applied to a SAM of the economy. CO2 emissions are estimated by means of the Leontief input-output submodel of the SAM, together with a table of coefficients of emissions per unit of monetary expenditures. This new methodology allows us to dispense with energy input-output tables for the base period. Our results are of the same order of magnitude as others obtained by physical measurement methods. We also simulate how changes in demand and energy energy efficiency parameters may affect CO2 emissions for the economy.

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. ATKs 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.

Evaluating impacts of CO2 gas intrusion into a confined sandstone aquifer: Experimental results  

SciTech Connect

Deep subsurface storage and sequestration of CO2 has been identified as a potential mitigation technique for rising atmospheric CO2 concentrations. Sequestered CO2 represents a potential risk to overlying aquifers if the CO2 leaks from the deep storage reservoir. Experimental and modeling work is required to evaluate potential risks to groundwater quality and develop a systematic understanding of how CO2 leakage may cause important changes in aquifer chemistry and mineralogy by promoting dissolution/precipitation, adsorption/desorption, and redox reactions. Sediments from the High Plains aquifer in Kansas, United States, were used in this investigation, which is part of the National Risk Assessment Partnership Program sponsored by the US Department of Energy. This aquifer was selected to be representative of consolidated sand and gravel/sandstone aquifers overlying potential CO2 sequestration repositories within the continental US. In this paper, we present results from batch experiments conducted at room temperature and atmospheric pressure with four High Plains aquifer sediments. Batch experiments simulate sudden, fast, and short-lived releases of the CO2 gas as would occur in the case of well failure during injection. Time-dependent release of major, minor, and trace elements were determined by analyzing the contacting solutions. Characterization studies demonstrated that the High Plains aquifer sediments were abundant in quartz and feldspars, and contained about 15 to 20 wt% montmorillonite and up to 5 wt% micas. Some of the High Plains aquifer sediments contained no calcite, while others had up to about 7 wt% calcite. The strong acid extraction tests confirmed that in addition to the usual elements present in most soils, rocks, and sediments, the High Plains aquifer sediments had appreciable amounts of As, Cd, Pb, Cu, and occasionally Zn, which potentially may be mobilized from the solid to the aqueous phase during or after exposure to CO2. However, the results from the batch experiments showed that the High Plains sediments mobilized only low concentrations of trace elements (potential contaminants), which were detected occasionally in the aqueous phase during these experiments. Importantly, these occurrences were more frequent in the calcite-free sediment. Results from these investigations provide useful information to support site selection, risk assessment, and public education efforts associated with geological CO2 storage and sequestration.

NETL: Bench-Scale Development of a Non-Aqueous Solvent CO2 Capture Process  

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

Bench-Scale Development of a Non-Aqueous Solvent (NAS) CO2 Capture Process for Coal-Fired Power Plants Bench-Scale Development of a Non-Aqueous Solvent (NAS) CO2 Capture Process for Coal-Fired Power Plants Project No.: DE-FE0013865 Research Triangle Institute (RTI) is continuing the development process for a non-aqueous solvent (NAS)-based CO2 capture process that was originated at laboratory scale under an ARPA-E project. This project will conduct bench-scale testing to show the potential of the technology to reduce the parasitic energy penalty. Key technical and economic challenges and uncertainties to be addressed include solvent makeup cost, scalable regenerator design, development of a complete NAS process arrangement, and improved confidence in the capital cost estimate that will enable the scale up of the process. One major focus is identification of best-candidate NAS formulations. This will entail reducing solvent makeup costs by reducing the formulation cost. In addition, efforts will be made to reduce evaporative and degradation losses while maintaining the desired CO2 absorption chemistry. A second focus area involves advancing the design of the process. This will be done by developing and evaluating the effectiveness of two process units specific to NASs - the NAS Recovery/Wash Section and NAS Regenerator. As the project proceeds, the testing campaign will evaluate thermal regeneration energy requirements [kJt / kg CO2] and develop a detailed understanding of the operation of the process. Preliminary analyses indicate that the NAS process can reduce energy consumption by 30 to 50 percent compared to current state of the art CO2 capture processes.

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.

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.

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,

CO2 Huff-n-Puff Process in a Light Oil Shallow Shelf Carbonate Reservoir  

SciTech Connect

The principal objective of the Sundown Slaughter Unit (SSU) CO2 Huff- n- Puff (H- n- P) project is to determine the feasibility and practicality of the technology in a waterflooded shallow shelf carbonate environment. Sundown Slaughter Unit is the second demonstration site associated with this project, following the unsuccessful test at Central Vacuum Unit. The ultimate goal will be to develop guidelines based on commonly available data that other operators in the industry can use to investigate the applicability of the process within other fields. The technology transfer objective of the project is to disseminate the knowledge gained through an innovative plan in support of the Department of Energy's (DOE) objective of increasing domestic oil production and deferring the abandonment of shallow shelf carbonate (SSC) reservoirs. Tasks associated with this objective are carried out in what is a timely effort for near- term goals. The goal of this Sundown Slaughter Unit Project is to demonstrate the CO2 Huff- n- Puff process in a waterflooded, light oil, shallow shelf carbonate reservoir within the Permian Basin. The CO2 Huff- n- Puff process is a proven enhanced oil recovery technology for Louisiana- Texas gulf coast sandstone reservoirs. The reader is referred to three Society of Petroleum Engineer (SPE) papers, No. 15502, No. 16720 & No. 20208 for a review of the theory, mechanics of the process, and several case histories. The process has even been shown to be moderately effective in conjunction with steam on heavy California crude oils. Although the technology is proven in gulf coast sandstones, it continues to be a very underutilized enhanced recovery option for carbonates. The goal of this technology demonstration is to gain an overall understanding of the reservoir qualities that influence CO2 Huff- n- Puff production responses within a heterogeneous reservoir such as the shallow shelf carbonate environment of the Sundown Slaughter Unit. A generalized reservoir model was developed and used to determine the importance of various geological and operational influences upon the CO2 Huff- n- Puff process at CVU. The findings at CVU would be applied to the demonstration site at SSU without further simulation studies being conducted at SSU.

Exploring the effects of data quality, data worth, and redundancy of CO2 gas pressure and saturation data on reservoir characterization through PEST Inversion  

SciTech Connect

This study examined the impacts of reservoir properties on CO2 migration after subsurface injection and evaluated the possibility of characterizing reservoir properties using CO2 monitoring data such as saturation distribution. The injection reservoir was assumed to be located 1400-1500 m below the ground surface such that CO2 remained in the supercritical state. The reservoir was assumed to contain layers with alternating conductive and resistive properties, which is analogous to actual geological formations such as the Mount Simon Sandstone unit. The CO2 injection simulation used a cylindrical grid setting in which the injection well was situated at the center of the domain, which extended up to 8000 m from the injection well. The CO2 migration was simulated using the PNNL-developed simulator STOMP-CO2e (the water-salt-CO2 module). We adopted a nonlinear parameter estimation and optimization modeling software package, PEST, for automated reservoir parameter estimation. We explored the effects of data quality, data worth, and data redundancy on the detectability of reservoir parameters using CO2 saturation monitoring data, by comparing PEST inversion results using data with different levels of noises, various numbers of monitoring wells and locations, and different data collection spacing and temporal sampling intervals. This study yielded insight into the use of CO2 saturation monitoring data for reservoir characterization and how to design the monitoring system to optimize data worth and reduce data redundancy.

Western Europe » Italy Western Europe » Italy (including San Marino) Italy (including San Marino) Fossil-Fuel CO2 Emissions Graph graphic Graphics Data graphic Data Trends As occurred in many industrialized nations, CO2 emissions from Italy rose steeply since the late 1940's until the growth was abruptly terminated in 1974. Since 1974, emissions from liquid fuels have vacillated, dropping from 76% to 46% of a static but varying total. Significant increases in natural gas consumption have compensated for the drop in oil consumption. In 2008, 35.8% of Italy's fossil-fuel CO2 emissions were due to natural gas consumption. Coal usage grew steadily until 1985 when CO2 emissions from coal consumption reached 16 million metric tons of carbon. Not until 2004 did coal usage exceed 1985 levels and now accounts for 13.9% of Italy's

The advantages of this solution are that CO2 has a low heat capacity, a low heat of vaporization and low viscosity. Thus, the liquid CO2 imposes a much smaller thermal load on the gasifier relative to a water slurry, and has the potential to improve the efficiency and economics of integrated gasification combined cycle (IGCC) power plants with carbon capture and dramatically reduce greenhouse gas emissions from coal fired power plants.

Carbon Dioxide Flux Measurement Systems (CO2Flux) Handbook  

SciTech Connect

The Southern Great Plains (SGP) carbon dioxide flux (CO2 flux) measurement systems provide half-hour average fluxes of CO2, H2O (latent heat), and sensible heat. The fluxes are obtained by the eddy covariance technique, which computes the flux as the mean product of the vertical wind component with CO2 and H2O densities, or estimated virtual temperature. A three-dimensional sonic anemometer is used to obtain the orthogonal wind components and the virtual (sonic) temperature. An infrared gas analyzer is used to obtain the CO2 and H2O densities. A separate sub-system also collects half-hour average measures of meteorological and soil variables from separate 4-m towers.

Optimizing heat integration in a flexible coalnatural gas power station with CO2 capture  

Science Journals Connector (OSTI)

Abstract Computational optimization is used to simultaneously determine the design and planned operating profile of a flexible coalnatural gas power station with CO2 capture, under a CO2 emission performance standard. The facility consists of a coal-fired power station undergoing retrofit with CO2 capture. The CO2 capture energy demand is provided by a specially designed combined cycle gas turbine (CCGT). The heat recovery steam generator (HRSG) component of the CCGT is modeled and optimized in detail, with explicit treatment of the discrete aspects of the HRSG configuration, including the number and sequential arrangement of HRSG internal components. Variable facility operations are represented by discrete operating modes selected based on the electricity priceduration curve. Two objectives, the minimization of capital requirement and the maximization of net present value, are considered in a bi-objective mixed-integer nonlinear programming formulation. Pareto frontiers, which define the optimal tradeoffs between these two objectives, are generated for six scenarios constructed from recent historical data from West Texas, the United Kingdom, and India. For a 440MW coal plant in a scenario based on 2011 West Texas data, the minimum effective net present cost required for the retrofit (which meets the CO2 emission performance standard) varies from $278 to 383million, and the minimum total capital investment requirement ranges from $346 to 517million. The variations in these optimized values correspond to the range of the Pareto frontier within the bounds of the problem. The net present cost of the retrofit is less than the present value of the existing coal plant, $476million, indicating that a retrofit is preferred over decommissioning. In the case of very low energy prices, however, decommissioning is shown to be the preferred option. The UK and India scenarios demonstrate that optimal designs can vary greatly depending upon location-specific economic conditions.

The Potential for Increased Atmospheric CO2 Emissions and Accelerated Consumption of Deep Geologic CO2 Storage Resources Resulting from the Large-Scale Deployment of a CCS-Enabled Unconventional Fossil Fuels Industry in the U.S.  

SciTech Connect

Desires to enhance the energy security of the United States have spurred significant interest in the development of abundant domestic heavy hydrocarbon resources including oil shale and coal to produce unconventional liquid fuels to supplement conventional oil supplies. However, the production processes for these unconventional fossil fuels create large quantities of carbon dioxide (CO2) and this remains one of the key arguments against such development. Carbon dioxide capture and storage (CCS) technologies could reduce these emissions and preliminary analysis of regional CO2 storage capacity in locations where such facilities might be sited within the U.S. indicates that there appears to be sufficient storage capacity, primarily in deep saline formations, to accommodate the CO2 from these industries. Nevertheless, even assuming wide-scale availability of cost-effective CO2 capture and geologic storage resources, the emergence of a domestic U.S. oil shale or coal-to-liquids (CTL) industry would be responsible for significant increases in CO2 emissions to the atmosphere. The authors present modeling results of two future hypothetical climate policy scenarios that indicate that the oil shale production facilities required to produce 3MMB/d from the Eocene Green River Formation of the western U.S. using an in situ retorting process would result in net emissions to the atmosphere of between 3000-7000 MtCO2, in addition to storing potentially 900-5000 MtCO2 in regional deep geologic formations via CCS in the period up to 2050. A similarly sized, but geographically more dispersed domestic CTL industry could result in 4000-5000 MtCO2 emitted to the atmosphere in addition to potentially 21,000-22,000 MtCO2 stored in regional deep geologic formations over the same period. While this analysis shows that there is likely adequate CO2 storage capacity in the regions where these technologies are likely to deploy, the reliance by these industries on large-scale CCS could result in an accelerated rate of utilization of the nations CO2 storage resource, leaving less high-quality storage capacity for other carbon-producing industries including electric power generation.

CO2 Supermarket Refrigeration Systems for Southeast Asia and the USA  

SciTech Connect

This paper presents a comparative analysis of the annual energy consumption of these refrigeration systems in eighty eight cities from all climate zones in Southeast Asia. Also, the performance of the CO2 refrigeration systems is compared to the baseline R404A multiplex direct expansion (DX) system. Finally, the overall performance of the CO2 refrigeration systems in various climatic conditions in Southeast Asia is compared to that in the United States. For the refrigeration systems investigated, it was found that the Transcritical Booster System with Bypass Compressor (TBS-BC) performs better or equivalent to the R404A multiplex DX system in the northern regions of Southeast Asia (China and Japan). In the southern regions of Southeast Asia (India, Bangladesh, Burma), the R404A multiplex DX system and the Combined Secondary Cascade (CSC) system performs better than the TBS-BC.

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.

Comparative assessment of sub-critical versus advanced super-critical oxyfuel fired PF boilers with CO2 sequestration facilities  

Science Journals Connector (OSTI)

This work focuses on the techno-economic assessment of bituminous coal fired sub- and super-critical pulverised fuel boilers from an oxyfuel based CO2 capture point of view. At the initial stage, two conventional power plants with a nominal power output of above 600MWe based on the above steam cycles are designed, simulated and optimised. Built upon these technologies, CO2 capture facilities are incorporated within the base plants resulting in a nominal power output of 500MWe. In this manner, some sensible heat generated in the air separation unit and the CO2 capture train can be redirected to the steam cycle resulting in a higher plant efficiency. The simulation results of conventional sub- and super-critical plants are compared with their CO2 capture counterparts to disclose the effect of sequestration on the overall system performance attributes. This systematic approach allows the investigation of the effects of the CO2 capture on both cycles. In the literature, super-critical plants are often considered for a CO2 capture option. These, however, are not based on a systematic evaluation of these technologies and concentrate mainly on one or two key features. In this work several techno-economic plant attributes such as the fuel consumptions, the utility usages, the plant performance parameters as well as the specific CO2 generation and capture rates are calculated and weighed against each other. Finally, an economic evaluation of the system is conducted along with sensitivity analyses in connection with some key features such as discounted cash flow rates, capital investments and plant efficiencies as well as fuel and operating costs.

CO2 Sequestration Potential of the North Michigan Silurian Reef CO2 Sequestration Potential of the North Michigan Silurian Reef CO2 Sequestration Potential of the North Michigan Silurian Reef Authors: Brian Toelle, Chaoqing Yang (speaker), and Tracee Imai, Schlumberger Ltd. Venue: Eastern Section of the American Association of Petroleum Geologists 2007 Annual Meeting, Lexington, KY, September 16–18, 2007 (http://www.uky.edu/KGS/esaapg07/ [external site]). Abstract: The Northern Silurian Reef trend of the Michigan Basin was developed within the stratigraphic unit historically referred to as the Niagaran Brown. Within the past few years this unit was renamed the Guelph Formation. Over 700 reefs make up this trend, with some of these being over 300 acres in size and having produced more than 5 million barrels of oil. Estimates of the total amount of hydrocarbons produced for the entire trend have been reported to be as much as nearly a half a billion barrels. The U.S. Department of Energy has funded a study of an ongoing enhanced oil recovery project being conducted on a reef within this trend and entailing CO2 injection. The Charlton 30/31 reef, located in Otsego County, MI, like many other reefs in the play, was discovered and developed during the 1970s and 1980s. This field has completed its primary production phase, during which six wells produced 2.6 million of the field’s estimated 7 million barrels of oil in place. This reservoir is characterized as a low-porosity, low-permeability limestone matrix with irregular dolomitized intervals providing a secondary network of higher porosity and permeability, which controls fluid flow throughout the reservoir. The estimated average porosity in this reef is just slightly over 6 percent. As part of this study, the reservoir attributes identified at the Charlton 30/31 reef were extended to the entire Northern Reef Trend in order to determine its CO2 sequestration capacity. Additionally, the potential oil recovery has been estimated.

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.

Novel Flow Sheet for Low Energy CO2 Capture Enabled by Biocatalyst Delivery System Novel Flow Sheet for Low Energy CO2 Capture Enabled by Biocatalyst Delivery System Project No.: DE-FE0012862 Akermin is conducting laboratory and integrated bench-scale pilot testing to validate the performance of their next generation Biocatalyst Delivery System (BDS). This effort builds upon work conducted under a previous project. The novel system enables on-stream replacement of the catalyst and enables integration with an advanced process flow scheme. Akermin is exploring an enzyme-enabled advanced process flow scheme with non-volatile capture solutions, AKM-24 and potassium carbonate. The advanced process flow scheme is projected to have lower parasitic energy requirements and lower capital costs resulting in greater than 30 percent reduction in the cost of capture. The novel flow sheet enabled by the biocatalyst permits regeneration at lower temperatures allowing heat integration with the lowest grade steam from the power plant and minimizing water consumption. The existing 500 standard liters per minute (SLPM) bench unit will be modified to incorporate the next-generation BDS, accommodate the new process flow scheme, and reduce heat loss for better quantification of energy performance. The modified bench unit will be operated at the National Carbon Capture Center on actual flue gas.

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 60100% larger for the lower-ranked coals. The heat of adsorption, after correcting for volumetric effects, was fairly constant (261 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.

Heat Exchanger Network Design and Economic Analysis for Coal-fired Power Plant retrofitted with CO2 Capture  

Science Journals Connector (OSTI)

Abstract Addition of CO2 capture unit to an existing power plant to satisfy environmental regulations has adverse effects on the energy efficiency of the power plant. Heat integration through proper design of heat exchanger network (HEN) remains the most effective way to reduce this energy penalty as well as reducing CO2 emission. Pinch technology remains the most widely used techniques due to its physical insight. This paper aims to present HEN design and economic analysis for power plant retrofitted with post-combustion CO2 capture. The benchmark presented is based on the recent work of Khalilpour and Abbas (2011) (i.e. Ref. [1]). Improvements to Khalilpour and Abbas (2011) include: (1) the use of cost and economic data to evaluate achievable trade-offs between energy, capital and utility cost. This is to determine the optimal minimum temperature difference; (2) redesigning of HEN with the newly determined minimum temperature difference and (3) its comparison with the HEN design presented in Ref. [1]. The results show that the energy penalty imposed on the power plant with CO2 capture plant can be reduced through heat integration of HEN, thus utility cost savings was maximized and the cost of addition of HEN was recovered within a short payback period of about 2.8 years.

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

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

Science Journals Connector (OSTI)

Increased use of natural gas has been promoted as a means of decarbonizing the US power sector, because of superior generator efficiency and lower CO2 emissions per unit of electricity than coal. We model the effect of different gas supplies on the US power sector and greenhouse gas (GHG) emissions. Across a range of climate policies, we find that abundant natural gas decreases use of both coal and renewable energy technologies in the future. Without a climate policy, overall electricity use also increases as the gas supply increases. With reduced deployment of lower-carbon renewable energies and increased electricity consumption, the effect of higher gas supplies on GHG emissions is small: cumulative emissions 201355 in our high gas supply scenario are 2% less than in our low gas supply scenario, when there are no new climate policies and a methane leakage rate of 1.5% is assumed. Assuming leakage rates of 0 or 3% does not substantially alter this finding. In our results, only climate policies bring about a significant reduction in future CO2 emissions within the US electricity sector. Our results suggest that without strong limits on GHG emissions or policies that explicitly encourage renewable electricity, abundant natural gas may actually slow the process of decarbonization, primarily by delaying deployment of renewable energy technologies.

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.

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 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.

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.

9 - Oxyfuel combustion systems and technology for carbon dioxide (CO2) capture in power plants  

Science Journals Connector (OSTI)

Abstract: Oxyfuel combustion uses pure oxygen instead of air to burn carbonaceous materials, resulting in a CO2 separation efficiency theoretically close to 100% should the fuel and oxygen be free of contaminants. This chapter examines several oxyfuel systems, considering two categories of power cycle those based on steam cycles and those based on gas cycles both of which generate oxygen using a cryogenic air separation unit. Also covered is the AZEP cycle, which belongs in the second category but which uses a ceramic membrane integrated into the system to separate oxygen from air. Oxy-combustion in IGCC plants and in gas turbine cycles integrating solid oxide fuel cells is also examined here as a low emission process. The technical issues and future potential for each option are discussed and reference is made to several pilot installations and ongoing R & D projects.

CO2 conversion for syngas production in methane catalytic partial oxidation  

Science Journals Connector (OSTI)

Abstract The catalytic partial oxidation of methane (CPOM) involves the interaction among methane combustion (MC), steam reforming (SR), and dry reforming (DR), and CO2 generated from MC is utilized for syngas production in DR. To evaluate the potential of CO2 utilization in CPOM for syngas production, a numerical study is carried out where CO2 is added into the feed gas and CPOM is triggered in a rhodium-based catalyst bed. Two important parameters of CO2/O2 ratio and O2/CH4 ratio (or O/C ratio) in the feed gas are taken into account. The predictions suggest that CO2 addition plays no part in MC, but it retards SR and intensifies DR. The CO2 consumption increases with CO2/O2 ratio; however, the CO2 conversion goes down. As a whole, increasing CO2 addition enhances CO formation but reduces H2 formation. The maximum syngas production is exhibited at CO2/O2=0.2 when the O/C ratio is 1. At a fixed CO2/O2 ratio, the maximum H2 yield and CO2 consumption are located at O/C=1.8 and 1.0, respectively. However, the CO2 conversion monotonically decreases with increasing O/C ratio. Within the investigated range of CO2/O2 and O/C ratios, the H2 yield and CO2 conversion in CPOM are in the ranges of approximately 0.421.34mol(molCH4)?1 and 1041%, respectively.

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 1000MW Power Station and confirmed successful, long term demonstration following ?5000hours of operation in 200607 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

A Low Cost, High Capacity Regenerable Sorbent for CO2 Capture from Existing Coal-Fired Power Plants A Low Cost, High Capacity Regenerable Sorbent for CO2 Capture from Existing Coal-Fired Power Plants Project No.: DE-FE0007580 TDA Research, Inc is developing a low cost, high capacity CO2 adsorbent and demonstrating its technical and economic viability for post-combustion CO2 capture for existing pulverized coal-fired power plants. TDA is using an advanced physical adsorbent to selectively remove CO2 from flue gas. The sorbent exhibits a much higher affinity to adsorb CO2 than N2, H2O or O2, enabling effective CO2 separation from the flue gas. The sorbent binds CO2 more strongly than common a
