Analysis of a precipitating solvent absorption process for reducing CO2 emissions from black coal fired power generation

摘要: Abstract Carbon capture and storage (CCS) is a technology that has the potential to provide deep cuts in CO 2 emissions from coal-fired power generation. This paper describes retrofitting CO2CRC's low cost “UNO MK 3” precipitating potassium carbonate (K 3 ) process 335 MW (net) black subcritical station, typical of those Australia. The use heat integration reduce net energy penalty also studied modifications required steam cycle for these cases are outlined. Retrofitting UNO smaller compared with amine-based processes. Heat strategies can this by an additional 20%. To further impact on output option partial described here. In case, intensity station equivalent natural gas combined (NGCC) station. A detailed analysis various without performed. results suggest standard solvent technologies, up 50% savings avoided. levelised electricity reduces 35% using commercial technologies.
