The flue stream is contacted with a predetermined sorbent system to remove acid gases from the flue stream. The acid gas-rich sorbent is then heated to desorb the acid gas for capture and regenerate the sorbent. Heat exchangers and heat pumps are used to reduce utility steam and/or cooling water consumption.application/pdfPatenthttp://pimg-fpiw.uspto.gov/fdd/64/516/107/0.pdf15316732B01D53/1475B01D53/1425B01D53/1462B01D2252/20405B01D2252/20421B01D2252/20431B01D2252/20484B01D2252/20489B01D2252/504B01D2257/304B01D2257/504B01D2259/652Y02C20/4010751664
