Claim 8:
9. A method of capturing carbon dioxide from a flue gas, comprising:
compressing the flue gas into a compressed flue gas stream at a compression rate determined by external electricity demand;
delivering a first portion of the flue gas stream to a membrane-based carbon dioxide separation unit;
delivering a second portion of the compressed flue gas stream to aqueous-based carbon dioxide capture unit; and
processing the compressed flue gas stream in parallel in the membrane-based carbon dioxide separation unit and the aqueous-based carbon dioxide capture unit without recycling any carbon dioxide removed from the compressed flue gas stream to the compressor, the membrane-based carbon dioxide separation unit and the aqueous-based carbon dioxide capture unit.
