Available in PDF, EPUB and Kindle. Book excerpt: SaskPower's Integrated Carbon Capture and Storage Demonstration Project on Boundary Dam's Unit 3 pioneered the way for full-scale carbon capture facilities around the world. With such an undertaking, many lessons were learned through the design, construction and operations of the facility. These lessons have resulted in novel optimizations, operating methods and overall learnings for the facility and its role as a power generator in the power utility. Saskatchewan and its provincial utility, SaskPower, again find themselves on the cusp of an important decision. The utility has a need to provide base-load power which regionally is only available from coal or natural gas. Regulations in Canada are closing the window on coal-fired power generation without carbon capture, and while there is a significant revenue opportunity to utilize and sequester CO2 for Enhanced Oil Recovery (EOR) operations, low oil prices have softened the demand for the CO2. The economics of retrofitting coal with Carbon Capture and Storage (CCS) are further challenged by locally all-time low natural gas prices. The International CCS Knowledge Centre (Knowledge Centre) is currently executing a feasibility study with SaskPower to determine if a business case can be made for a post combustion carbon capture retrofit of the 305MW Shand Power Station. The study included the addition of a 90% carbon capture facility that will have a nominal annual capacity of 2 million tonnes per year. This paper includes interpretation of the public and non-confidential portion of this study to highlight both the overall impact on the cost of CO2 capture, as well as contrasting the impact of the major design modifications with the Boundary Dam Unit 3 system (BD3).

This book was released on 2022-12-26 with total page 178 pages. Available in PDF, EPUB and Kindle. Book excerpt: A shift towards implementation of renewable energy has disadvantages, such as power availability, storage capacity, and accompanying costs, and therefore the potential of clean fossil fuel technologies to ensure the stability of electricity generation needs to be reconsidered until these challenges will be overcome. These clean technologies can help prevent the greenhouse effect and, at the same time, guarantee energy security, as coal is a widespread, price-stable raw material that is available in large quantities. This book focuses on the carbon chain, starting from the formation of CO2, through its capture, possible cleaning, to the production of useful products such as dimethylether, methanol, and carbonated cement prefabricates. The comprehensive case study presents the research results of an international team established within the "CCS-CCU technology for carbon footprint reduction using bio-adsorbents" (BIOCO2) project.

Download or read book Using Auxiliary Gas Power for Carbon Capture and Storage Energy Needs in Retrofitted Coal Power Plants written by Sarah Omer Bashadi and published by . This book was released on 2010 with total page 97 pages. Available in PDF, EPUB and Kindle. Book excerpt: Post-combustion capture retrofits are expected to a near-term option for mitigating CO 2 emissions from existing coal-fired power plants. Much of the literature proposes using power from the existing coal plant and thermal integration of its supercritical steam cycle with the stripper reboiler to supply the energy needed for solvent regeneration and CO2 compression. This study finds that using an auxiliary natural gas turbine plant to meet the energetic demands of carbon capture and compression may make retrofits more attractive compared to using thermal integration in some circumstances. Natural gas auxiliary plants increase the power output of the base plant and reduce technological risk associated with CCS, but require favorable natural gas prices and regional electricity demand for excess electricity to make using an auxiliary plant more desirable. Three different auxiliary plant technologies were compared to integration for 90% capture from an existing, 500 MW supercritical coal plant. CO2 capture and compression is simulated using Aspen Plus and a monoethylamine (MEA) absorption process. Thermoflow software is used to simulate three gas plant technologies. The three technologies assessed are the gas turbine (GT) with heat recovery steam generator (HRSG), gas turbine with HRSG and back pressure steam turbine, and natural gas boiler with back pressure steam turbine. The capital cost of the MEA unit is estimated using the Aspen Icarus Process Evaluator, and the capital cost of the external GT plants are estimated using the Thermoflow Plant Engineering and Cost Estimator. The gas turbine options are found to lead to electricity costs similar to integration, but their performance is highly sensitive to the price of natural gas and the economic impact of integration. Using a GT with a HRSG only has a lower capital cost but generates less excess electricity than the GT with HRSG and back pressure steam turbine. In order to generate enough steam for the reboiler, a significant amount of excess power was produced using both gas turbine configurations. This excess power could be attractive for coal plants located in regions with increasing electricity demand. An alternate capture plant scenario where a greater demand for power exists relative to steam is also considered. The economics of using auxiliary plant power improve slightly under this alternate energy profile scenario, but the most important factors affecting desirability of the auxiliary plant retrofit remain the cost of natural gas, the full cost of integration, and the potential for sale of excess electricity.

This book was released on 2013-06-10 with total page 16 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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. ). 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 . 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.

Download or read book Computational Optimization of Design and Variable Operation of CO2 capture enabled Coal natural Gas Power Plants written by Charles A. Kang and published by . This book was released on 2015 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Climate change mitigation will require large reductions in CO2 emissions from electricity production. Some of these cuts will come from increased use of renewable energy resources, but it is likely that thermal power plants will be used for an extended period of time to maintain grid stability and accommodate seasonal variability in renewable generation. Therefore, thermal power plants with CO2 capture and storage (CCS) capability may coexist with renewable generation to provide reliable low-carbon electricity. Moreover, CCS-enabled facilities designed for constant operations are not necessarily optimal under the conditions that are likely to occur with increased renewable penetration. There is therefore a need to devise optimal designs and operating plans for flexible thermal power stations equipped with CCS. In this work, computational optimization is used to determine the design and operating plan of a coal-natural gas power station with CO2 capture, under a CO2 emission performance standard. The facility consists of a coal power plant undergoing a retrofit with solvent-based post-combustion CO2 capture. The heat for CO2 capture solvent regeneration is provided by a combined cycle gas turbine (CCGT) designed for combined-heat-and-power service. Variable facility operations are represented by discrete operating modes dispatched using the electricity price-duration curve. Two problem formulations are considered. In the `simplified-capture' problem formulation, the CO2 capture system is represented using a single variable for capacity, while heat integration (including a detailed treatment of the heat recovery steam generator component of the CCGT) is optimized jointly with variable operations. In the `full-system' problem formulation, the detailed design of the CO2 capture system is optimized alongside a full treatment of heat integration and variable operations. To accomplish this, a computationally efficient proxy model of the CO2 capture system is developed that reproduces the behavior of a full-physics Aspen Plus model. Both problem formulations are incorporated in a bi-objective mixed-integer nonlinear program in which total capital requirement (TCR) is minimized and net present value (NPV) is maximized. Pareto frontiers are generated for six scenarios constructed from recent historical data from West Texas, the United Kingdom, and India. All six scenarios are considered using the simplified-capture problem formulation. The West Texas base scenario and the India scenario, which differ greatly from each other, are considered using the full-system problem formulation as well. Results between the two formulations are quite consistent and show that hourly electricity price variability and the choice of objective function can have a large effect on optimal design and planned operations. In the West Texas base scenario, which has high price variability, the maximum NPV facility in the full-system formulation (NPV of $201 million, TCR of $510 million) has a time-varying operating plan in which the CO2 capture system has a utilization factor of 66% (out of a maximum of 85%). In this scenario the minimum TCR facility (NPV of $101 million, TCR of $333 million) has a constant operating profile. In contrast, low price variability in the India scenario results in constant operations regardless of objective. Two advanced CO2 capture processes -- the mixed salt and piperazine processes -- are considered using the simplified-capture formulation for the West Texas base scenario. The advanced processes are shown to outperform the standard monoethanolamine (MEA) process, with the mixed salt process outperforming the MEA process by 16% for maximum NPV and 14% for minimum TCR. The full-system formulation using the MEA process provides generally similar results to those from the simplified-capture formulation in both the India and West Texas base scenarios. However, the inclusion of the detailed design of the CO2 capture process in the full-system problem formulation provides valuable design information, such as the effect of the integer nature of the number of CO2 capture trains. Taken in total, the results of this study highlight the value of applying computational optimization to consider integrated plant design and variable operations together.

Available in PDF, EPUB and Kindle. Book excerpt: Nationally-recognised studies and our contacts with a diverse group of industry representatives, non-governmental organisations, and academic researchers show that key barriers to CCS deployment include (1) underdeveloped and costly CO2 capture technology and (2) regulatory and legal uncertainties over CO2 capture, injection, and storage. Among the key technological barriers are a lack of experience in capturing significant amounts of CO2 from power plants and the significant cost of capturing CO2, particularly from existing coal-fired power plants, which are the single largest source of CO2 emissions in the United States. Compounding these technological issues are regulatory and legal uncertainties, including uncertainty regarding liability for CO2 leakage and ownership of CO2 once injected. According to the IPCC, the National Academy of Sciences, and other knowledgeable authorities, another barrier is the absence of a national strategy to control CO2 emissions (emissions trading plan, CO2 emissions tax, or other mandatory control of CO2 emissions), without which the electric utility industry has little incentive to capture and store its CO2 emissions. Moreover, according to key agency officials, the absence of a national strategy has also deterred their agencies from addressing other important practical issues, such as resolving how stored CO2 would be treated in a future CO2 emissions trading plan.

Available in PDF, EPUB and Kindle. Book excerpt: The project aims to develop a low-cost option for carbon capture in existing modern coal-fired power plants. The concept, known as ECO-Scrub, uses a novel combination of techniques employed in CO2 capture, such as oxygen enrichment and post-combustion solvent scrubbing, together with measures to increase efficiency, reduce steam consumption and generate power requirements. The project work involved development of the process, module integration and optimisation for lignite- and coal-fired power plants through programmes of laboratory- and pilot-scale tests, simulation modelling studies, literature reviews and collation of power plant performance data. The ECO-Scrub system was shown to be technically and economically feasible for retrofitting existing power plants for CO2 capture and sequestration. Optimising the oxygen enrichment level and the rate at which the flue gas is recycled were key parameters for achieving satisfactory combustion characteristics, low NOX emissions and improved heat transfer characteristics, and avoiding ash deposition problems. Preferentially enriching the staged air system with oxygen was an effective option for NOX control. A pilot-scale combustion test facility with oxyfuel capability, simulated flue gas recycling and equipped with a pilot-scale amine solvent scrubbing plant was used to evaluate the flexibility of the ECO-Scrub process and solvent performance. Membrane separation systems were shown to be promising alternatives to conventional CO2 capture methods for enriched CO2 flue gas. The cost and efficiency penalties for the ECO-Scrub process were comparable to those for post-combustion capture and oxyfuel combustion, however ECO-Scrub was shown to be more attractive as a retrofit option.

Available in PDF, EPUB and Kindle. Book excerpt: ALSTOM Power Inc.'s Power Plant Laboratories (ALSTOM) has teamed with American Electric Power (AEP), ABB Lummus Global Inc. (ABB), the US Department of Energy National Energy Technology Laboratory (DOE NETL), and the Ohio Coal Development Office (OCDO) to conduct a comprehensive study evaluating the technical feasibility and economics of alternate CO2 capture and sequestration technologies applied to an existing US coal-fired electric generation power plant. The motivation for this study was to provide input to potential US electric utility actions concerning GHG emissions reduction. If the US decides to reduce CO2 emissions, action would need to be taken to address existing power plants. Although fuel switching from coal to natural gas may be one scenario, it will not necessarily be a sufficient measure and some form of CO2 capture for use or disposal may also be required. The output of this CO2 capture study will enhance the public's understanding of control options and influence decisions and actions by government, regulators, and power plant owners in considering the costs of reducing greenhouse gas CO2 emissions. The total work breakdown structure is encompassed within three major reports, namely: (1) Literature Survey, (2) AEP's Conesville Unit No. 5 Retrofit Study, and (3) Bench-Scale Testing and CFD Evaluation.
