This talk is a review of conventional amine scrubbing for CO2 capture. Conventional amine scrubbing will be a dominant technology for post-combustion capture. Second generation amine scrubbing will provide an energy performance better than 50% thermodynamic efficiency, with an electricity burden approaching 200 kWh/tonne CO2 in the coal-fired application. 5 m PZ with absorber intercooling and the advanced flash stripper is a published second generation amine scrubbing process technology that should serve as the baseline for future improvements in post-combustion capture. This second generation technology has excellent energy performance, acceptable capital cost, and good amine stability. Amine aerosol emissions and amine oxidation are not yet completely understood and managed.
