Title: PROCESS FOR CARBON DIOXIDE RECAPTURE WITH IMPROVED ENERGY RECAPTURE
Abstract:
A method includes providing a stream containing carbon dioxide and at least one other condensable component; pressuring the stream containing carbon dioxide and at least one other condensable component to thereby produce a pressurized stream; and indirectly exchanging thermal energy between the pressurized stream and a thermal- energy accepting stream including a boilable component. A method includes providing a first stream containing carbon dioxide; adsorbing at least a portion of the carbon dioxide in the first stream in an adsorbing means; desorbing at least a portion of the carbon dioxide in the adsorbing means to obtain a desorbed carbon dioxide stream; and compressing the desorbed carbon dioxide stream immediately following said step of desorbing.
