A Summary of EPRI's Engineering and Economic Studies of Post Combustion Capture Retrofit Applied at Various North American Host Sites

摘要

With more than 300 GW of installed coal-fired plants in the US alone, and with many coal plants being currently built in China and India, it is conceivable that CO2 will lieed to be removed from these existing coal-fired plant assets to significantly reduce green house gas emissions to acceptable levels. The Electric Power Research Institute (EPRI) recently completed a series of detailed economic and engineering studies examining the feasibility of retrofitting post combustion capture (PCC) to existing pulverized coal (PC) and/or circulating fluidized-bed (CFB) power plants, for five different North American "host" sites. Whilst studies have previously considered optimized retrofit on theoretical plants, the current work focused on retrofitting existing "real world" assets. This paper provides a number of performance and costs results from the extensive retrofit evaluation, as well as providing additional insight on the technical results and economic comparisons that emerged.
