Title:
ENERGY-EFFICIENT EXTRACTION OF ACID GAS FROM FLUE GASES
Document Type and Number:
WIPO Patent Application WO/2015/188166
Kind Code:
A3
Abstract:
An energy-efficient method of removing carbon dioxide, hydrogen sulfide, and other acid gases from a stream of flue gases. 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.
