Abstract
A method for reducing energy requirements of a COcapture system comprises: contacting a flue gas stream with a COlean absorbent stream in an absorber, thereby removing COfrom the flue gas and providing a COrich absorbent stream; heating a first portion of the COrich absorbent stream using heat from the COlean absorbent stream, and providing the heated first portion of the COrich absorbent stream to a regenerator; providing a second portion of the COrich absorbent stream to the regenerator, wherein the heated first portion is hotter than the second portion and the heated first portion is provided to the regenerator at a lower elevation in the regenerator relative to that of the second portion.
