Abstract
A method and system for COcapture from flue gas uses an absorber vessel in which a flue gas stream containing COis contacted with an ammoniated solution to remove COfrom the flue gas, and a regenerator vessel in which COis released from the ammoniated solution. Parasitic energy consumption of the system can be reduced by adding to the ammoniated solution a promoter effective to enhance the formation of ammonium bicarbonate within the ammoniated solution. The amount of ammoniated solution recycled from the regenerator vessel to the absorber vessel is less than that which would be required using the ammoniated solution without the promoter for removal of the same amount of COfrom the flue gas.
