Book excerpt: A novel Gas Pressurized Stripping (GPS) post-combustion carbon capture (PCC) process has been developed by Carbon Capture Scientific, LLC, CONSOL Energy Inc., Nexant Inc., and Western Kentucky University in this bench-scale project. The GPS-based process presents a unique approach that uses a gas pressurized technology for CO2 stripping at an elevated pressure to overcome the energy use and other disadvantages associated with the benchmark monoethanolamine (MEA) process. The project was aimed at performing laboratory- and bench-scale experiments to prove its technical feasibility and generate process engineering and scale-up data, and conducting a techno-economic analysis (TEA) to demonstrate its energy use and cost competitiveness over the MEA process. To meet project goals and objectives, a combination of experimental work, process simulation, and technical and economic analysis studies were applied. The project conducted individual unit lab-scale tests for major process components, including a first absorption column, a GPS column, a second absorption column, and a flasher. Computer simulations were carried out to study the GPS column behavior under different operating conditions, to optimize the column design and operation, and to optimize the GPS process for an existing and a new power plant. The vapor-liquid equilibrium data under high loading and high temperature for the selected amines were also measured. The thermal and oxidative stability of the selected solvents were also tested experimentally and presented. A bench-scale column-based unit capable of achieving at least 90% CO2 capture from a nominal 500 SLPM coal-derived flue gas slipstream was designed and built. This integrated, continuous, skid-mounted GPS system was tested using real flue gas from a coal-fired boiler at the National Carbon Capture Center (NCCC). The technical challenges of the GPS technology in stability, corrosion, and foaming of selected solvents, and environmental, health and safety risks have been addressed through experimental tests, consultation with vendors and engineering analysis. Multiple rounds of TEA were performed to improve the GPS-based PCC process design and operation, and to compare the energy use and cost performance of a nominal 550-MWe supercritical pulverized coal (PC) plant among the DOE/NETL report Case 11 (the PC plant without CO2 capture), the DOE/NETL report Case 12 (the PC plant with benchmark MEA-based PCC), and the PC plant using GPS-based PCC. The results reveal that the net power produced in the PC plant with GPS-based PCC is 647 MWe, greater than that of the Case 12 (550 MWe). The 20-year LCOE for the PC plant with GPS-based PCC is 97.4 mills/kWh, or 152% of that of the Case 11, which is also 23% less than that of the Case 12. These results demonstrate that the GPS-based PCC process is energy-efficient and cost-effective compared with the benchmark MEA process.

This book was released on 2013 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Under the DOE's Innovations for Existing Plants (IEP) Program, Carbon Capture Scientific, LLC (CCS) is developing a novel gas pressurized stripping (GPS) process to enable efficient post-combustion carbon capture (PCC) from coal-fired power plants. A technology and economic feasibility study is required as a deliverable in the project Statement of Project Objectives. This study analyzes a fully integrated pulverized coal power plant equipped with GPS technology for PCC, and is carried out, to the maximum extent possible, in accordance to the methodology and data provided in ATTACHMENT 3 - Basis for Technology Feasibility Study of DOE Funding Opportunity Number: DE-FOA-0000403. The DOE/NETL report on "Cost and Performance Baseline for Fossil Energy Plants, Volume 1: Bituminous Coal and Natural Gas to Electricity (Original Issue Date, May 2007), NETL Report No. DOE/NETL-2007/1281, Revision 1, August 2007" was used as the main source of reference to be followed, as per the guidelines of ATTACHMENT 3 of DE-FOA-0000403. The DOE/NETL-2007/1281 study compared the feasibility of various combinations of power plant/CO2 capture process arrangements. The report contained a comprehensive set of design basis and economic evaluation assumptions and criteria, which are used as the main reference points for the purpose of this study. Specifically, Nexant adopted the design and economic evaluation basis from Case 12 of the above-mentioned DOE/NETL report. This case corresponds to a nominal 550 MWe (net), supercritical greenfield PC plant that utilizes an advanced MEAbased absorption system for CO2 capture and compression. For this techno-economic study, CCS' GPS process replaces the MEA-based CO2 absorption system used in the original case. The objective of this study is to assess the performance of a full-scale GPS-based PCC design that is integrated with a supercritical PC plant similar to Case 12 of the DOE/NETL report, such that it corresponds to a nominal 550 MWe supercritical PC plant with 90% CO2 capture. This plant has the same boiler firing rate and superheated high pressure steam generation as the DOE/NETL report's Case 12 PC plant. However, due to the difference in performance between the GPS-based PCC and the MEA-based CO2 absorption technology, the net power output of this plant may not be exactly at 550 MWe.

This book was released on 2015 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: This topical report presents the techno-economic analysis, conducted by Carbon Capture Scientific, LLC (CCS) and Nexant, for a nominal 550 MWe supercritical pulverized coal (PC) power plant utilizing CCS patented Gas Pressurized Stripping (GPS) technology for post-combustion carbon capture (PCC). Illinois No. 6 coal is used as fuel. Because of the difference in performance between the GPS-based PCC and the MEA-based CO2 absorption technology, the net power output of this plant is not exactly 550 MWe. DOE/NETL Case 11 supercritical PC plant without CO2 capture and Case 12 supercritical PC plant with benchmark MEA-based CO2 capture are chosen as references. In order to include CO2 compression process for the baseline case, CCS independently evaluated the generic 30 wt% MEA-based PCC process together with the CO2 compression section. The net power produced in the supercritical PC plant with GPS-based PCC is 647 MW, greater than the MEA-based design. The levelized cost of electricity (LCOE) over a 20-year period is adopted to assess techno-economic performance. The LCOE for the supercritical PC plant with GPS-based PCC, not considering CO2 transport, storage and monitoring (TS & M), is 97.4 mills/kWh, or 152% of the Case 11 supercritical PC plant without CO2 capture, equivalent to $39.6/tonne for the cost of CO2 capture. GPS-based PCC is also significantly superior to the generic MEA-based PCC with CO2 compression section, whose LCOE is as high as 109.6 mills/kWh.

This book was released on 2013-06-10 with total page 17 pages. Available in PDF, EPUB and Kindle. Book excerpt: A dynamic model of a post-combustion capture pilot plant is developed using Aspen Plus Dynamics. An innovative process control strategy is studied for regulating the water balance of the process. A washing section where the flue gas from the absorber is washed with cold water is included to the process in order to reduce the emissions of amine to the air. Control of the water balance in the solvent loop is successfully achieved by changing the washing water temperature. In previous publications regarding CO2 capture pilot plants, the regulation of the water balance always required a water make-up flow which appears here as unnecessary. Rejection of disturbances and different load reduction scenarios are tested to confirm the efficiency of this strategy. Potential operational problems of this control strategy are identified and solved.

Download or read book Towards Flexible Operation of Post combustion CO2 Capture from Brown Coal Derived Flue Gas written by Mai Tuyet Thi Bui and published by . This book was released on 2015 with total page 624 pages. Available in PDF, EPUB and Kindle. Book excerpt: The world's first commercial-scale CO2 capture plant in Boundary Dam power station uses amine-based post-combustion CO2 capture (PCC) technology (Boundary Dam, Canada). The issues of large energy requirement and high cost have hindered worldwide deployment of PCC. Flexible operation has been proposed as a way to improve the economic and technical feasibility of PCC. Flexible operation coordinates reductions in CO2 emissions with electricity demand by: (i) ramping up CO2 capture during periods of low energy demand, and (ii) turning down or switching off CO2 capture during high energy demand. The immediate and long term impact of process disturbances from flexible operation is unclear. This thesis investigates the technical influence of flexible operation during amine-based CO2 capture from brown coal derived flue gas. Dynamic pilot plant studies have provided practical experience in flexible operation of PCC plants. The pilot plant study demonstrates the successful implementation of flexible operation in the form of parameter step-changes to a PCC process. The PCC pilot plant is run by CSIRO and located at AGL Loy Yang in Australia. The operation of the PCC plant under a broad range of transient conditions has captured the dynamics of the process and provides suitable data dynamic model validation. Additionally, the density meters provide the advantage for online monitoring of liquid CO2 concentration. Statistical analysis revealed that data variance may occur due to changes in: (i) ambient temperature, (ii) MEA concentration, or (iii) amine degradation. Although PCC plants of different scales and configurations have different response times, it is likely the dynamic trends to parameter changes would be similar. Thus, the dynamic behaviour observed in this thesis is of greater significance compared to the absolute values. Based on this study, changing the flue gas flow rate would produce the most rapid response. The greatest CO2 removal percentage was achieved at the lowest flue gas flow rate or at the highest absorbent flow rate. However, the latter provides high CO2 removal percentage with significantly lower reboiler heat duty in terms of MJ/kg CO2. The steam pressure parameter provides the ability to adjust the temperature of all the columns simultaneously. This effect may be used to compensate for effects from ambient conditions or heat losses. Flexible operation of PCC is modelled using Aspen Plus Dynamics®. Dynamic modelling of flexible PCC operation in the pilot plant uses the following stand-alone models: (i) Absorber Column 2 (ABS2), (ii) Absorber column 1 (ABS1), and (iii) Stripper Column. Stand-alone models provide the advantage of greater flexibility compared to integrated models; also they carry-through of successive errors is avoided. Additionally, disturbances can be introduced to intermediate streams without convergence issues. Each stand-alone model simulates the following flexible operation scenarios: (i) step-changes in flue gas flow rate, (ii) step-changes in absorbent flow rate, and (iii) step-changes in steam pressure. Modelling of property changes individually, elucidates which properties generate the dynamic responses observed in the pilot plant. The overall effect observed in the step-changes scenarios was the result of a combination of property changes that occur in tandem. The combination of these property changes accurately describes the dynamic behaviour observed in the pilot plant results. Although the dynamic modelling could not replicate the absolute values obtained in the pilot plant, the models demonstrated the same trends observed in pilot plant results. The modelled behaviour and pilot plant observations are in agreement for comparisons of the following results: (i) column temperature, (ii) CO2 composition of the liquid product, (iii) CO2 composition of the vapour product, and (iv) CO2 removal/capture percentage. Modelled dynamic response is in agreement with pilot plant trends, despite the influence of non-ideal conditions (e.g. amine degradation, ambient temperature effects, heat loss). Some key novel outcomes of the dynamic modelling include: (i) Model specifications in Aspen Plus® and Aspen Plus Dynamics® are based on data from the CSIRO PCC pilot plant at AGL Loy Yang; (ii) Modelling of a PCC process with a double-absorber configuration; (iii) The process of converting equilibrium reactions into forward/reverse kinetic reactions is documented in detail; (iv) The number of equilibrium stages for this PCC study is greater compared to previous Aspen Plus Dynamics® studies by Lin et al. (2011), Lin et al. (2012) and Léonard et al. (2013); (v) Demonstrated the necessity of adjustment factors to achieve model agreement with experimental data (particular when pilot plant data is affected by non-ideal conditions); (vi) Compared the precision of different mass transfer coefficient correlations for rate-based PCC modelling.

Available in PDF, EPUB and Kindle. Book excerpt: Concern over the effects of airborne pollution, green house gases, and the impact of global warming has become a worldwide issue that transcends international boundaries, politics, and social responsibility. The 2nd Edition of Coal Energy Systems: Clean Coal Technology describes a new generation of energy processes that sharply reduce air emissions and other pollutants from coal-burning power plants. Coal is the dirtiest of all fossil fuels. When burned, it produces emissions that contribute to global warming, create acid rain, and pollute water. With all of the interest and research surrounding nuclear energy, hydropower, and biofuels, many think that coal is finally on its way out. However, coal generates half of the electricity in the United States and throughout the world today. It will likely continue to do so as long as it's cheap and plentiful [Source: Energy Information Administration]. Coal provides stability in price and availability, will continue to be a major source of electricity generation, will be the major source of hydrogen for the coming hydrogen economy, and has the potential to become an important source of liquid fuels. Conservation and renewable/sustainable energy are important in the overall energy picture, but will play a lesser role in helping us satisfy our energy demands today. Dramatically updated to meet the needs of an ever changing energy market, Coal Energy Systems, 2nd Edition is a single source covering policy and the engineering involved in implementing that policy. The book addresses many coal-related subjects of interest ranging from the chemistry of coal and the future engineering anatomy of a coal fired plant to the cutting edge clean coal technologies being researched and utilized today. A 50% update over the first edition, this new book contains new chapters on processes such as CO2 capture and sequestration, Integrated Gasification Combined Cycle (IGCC) systems, Pulverized-Coal Power Plants and Carbon Emission Trading. Existing materials on worldwide coal distribution and quantities, technical and policy issues regarding the use of coal, technologies used and under development for utilizing coal to produce heat, electricity, and chemicals with low environmental impact, vision for utilizing coal well into the 21st century, and the security coal presents. - Clean Liquids and Gaseous Fuels from Coal for Electric Power - Integrated Gasification Combined Cycle (IGCC) systems - Pulverized-Coal Power Plants - Advanced Coal-Based Power Plants - Fluidized-Bed Combustion Technology - CO2 capture and sequestration
