Available in PDF, EPUB and Kindle. Book excerpt: Regenerable sorbents based on sodium carbonate (Na2CO3) can be used to separate carbon dioxide (CO2) from coal-fired power plant flue gas. Upon thermal regeneration and condensation of water vapor, CO2 is released in a concentrated form that is suitable for reuse or sequestration. During the research project described in this report, the technical feasibility and economic viability of a thermal-swing CO2 separation process based on dry, regenerable, carbonate sorbents was confirmed. This process was designated as RTI's Dry Carbonate Process. RTI tested the Dry Carbonate Process through various research phases including thermogravimetric analysis (TGA); bench-scale fixed-bed, bench-scale fluidized-bed, bench-scale co-current downflow reactor testing; pilot-scale entrained-bed testing; and bench-scale demonstration testing with actual coal-fired flue gas. All phases of testing showed the feasibility of the process to capture greater than 90% of the CO2 present in coal-fired flue gas. Attrition-resistant sorbents were developed, and these sorbents were found to retain their CO2 removal activity through multiple cycles of adsorption and regeneration. The sodium carbonate-based sorbents developed by RTI react with CO2 and water vapor at temperatures below 80 C to form sodium bicarbonate (NaHCO3) and/or Wegscheider's salt. This reaction is reversed at temperatures greater than 120 C to release an equimolar mixture of CO2 and water vapor. After condensation of the water, a pure CO2 stream can be obtained. TGA testing showed that the Na2CO3 sorbents react irreversibly with sulfur dioxide (SO2) and hydrogen chloride (HCl) (at the operating conditions for this process). Trace levels of these contaminants are expected to be present in desulfurized flue gas. The sorbents did not collect detectable quantities of mercury (Hg). A process was designed for the Na2CO3-based sorbent that includes a co-current downflow reactor system for adsorption of CO2 and a steam-heated, hollow-screw conveyor system for regeneration of the sorbent and release of a concentrated CO2 gas stream. An economic analysis of this process (based on the U.S. Department of Energy's National Energy Technology Laboratory's [DOE/NETL's] 'Carbon Capture and Sequestration Systems Analysis Guidelines') was carried out. RTI's economic analyses indicate that installation of the Dry Carbonate Process in a 500 MW{sub e} (nominal) power plant could achieve 90% CO2 removal with an incremental capital cost of about $69 million and an increase in the cost of electricity (COE) of about 1.95 cents per kWh. This represents an increase of roughly 35.4% in the estimated COE - which compares very favorable versus MEA's COE increase of 58%. Both the incremental capital cost and the incremental COE were projected to be less than the comparable costs for an equally efficient CO2 removal system based on monoethanolamine (MEA).

Download or read book Carbon Dioxide Capture from Coal fired Power Plant Flue Gas on Carbonaceous Sorbents written by Kaspars Krutkramelis and published by . This book was released on 2010 with total page 105 pages. Available in PDF, EPUB and Kindle. Book excerpt: Solid state carbonaceous sorbents are tested and evaluated as potential materials for CO2 capture from coal-fired power plant flue gas. In order to establish economic viability for CO2 capture of carbon materials, elementary adsorption and regeneration experiments have been performed. It has been known that carbon materials have fairly low heat of sorption towards CO2, approximately 20 [kJ/mol CO2] for AC-1. This is advantageous, if one considers and anticipates approximately similar regeneration energy for CO2 release and capture. However, further research in desorption methods demonstrates significantly larger regeneration energy requirements than previously thought. An original direct steam regeneration approach requires theoretical regeneration energy at approximately 311 [kJ/mol CO2] and experimental measurements suggest values closer to 443 [kJ/mol CO2]. Vacuum regeneration is explored next as a potential method for lower desorption energy. It is found that the vacuum desorption process is a considerably better selection with approximately 28 [kJ/mol CO2] theoretical energy requirement for ambient pressure sorption, and 56 and, 85 [kJ/mol CO2] for 3.92 [bar] and 9.72 [bar] PSA respectively. Nevertheless, due to efficiency limitations of physical vacuum systems, CO2 capture by vacuum desorption surges to approximately 101 [kJ/mol CO2] for ambient pressure sorption, and the best case scenario CO2 nominal capture cost is calculated at $40.49/tCO2.

This book was released on 2007 with total page 220 pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: Greenhouse gas emissions into the atmosphere have become an issue of concern with the increase in global population and demand for energy. In response to the demand for carbon emissions control, The Ohio State University has developed a novel high temperature multi-pollutant capture process that simultaneously captures carbon dioxide (CO2) and sulfur dioxide (SO2) from fossil fuels combustion flue gas streams. The multi- cyclic Carbonation Calcination Reaction (CCR) process utilizes a calcium-based sorbent in a high temperature reaction (carbonation) to capture the CO2 from the flue gas stream and releases a pure stream of CO2 that can be sequestered in the subsequent calcination reaction. The overall success of the technology depends on the development and optimization of the carbonation and calcination processes to create an integrated, cost and energy efficient process for carbon capture. The development of the CCR technology was further advanced from bench-scale research to an integrated, continuous, sub-pilot scale demonstration. Single-pass carbonation studies demonstrated high CO2 and SO2 removals using commercial calcium hydroxide as the sorbent in an entrained bed reactor. The high inherent pore volume of the commercial calcium hydroxide sorbent resulted in its demonstration of over 4 times the CO2 removal than commercial pulverized lime under similar process conditions. Bench-scale studies of the calcium carbonate (CaCO3) calcination reaction were conducted in the presence of steam and CO2 to effectively regenerate the spent CaCO3 sorbent in a manner suited for a carbon capture system. CaCO3 calcination in the presence of steam in the reactor lowers the partial pressure of CO2 such that complete calcination can be achieved at temperatures of 7500C and greater with significantly reduced calcination residence times. The resultant product CaO surface morphology is comparable to those achieved in calcination conditions of 100% CO2 despite known sintering effects of water vapor on the ionic structure of CaO.
