Patent ID: 8535502

Claim:
A system for recovery of CO 2 comprising: an aqueous capture device including a capture solution, the aqueous capture device arranged to receive gas and to capture components from the gas including at least CO 2 ; an electrodialysis unit in operative connection with the capture device to perform an electrodialysis operation on the capture solution including at least the CO 2 ; and monitors for monitoring pH of the system, wherein: a CO 2 rich process stream and a regenerated capture solution are generated from the capture solution including at least the CO 2 , the regenerated capture solution being sent back to the aqueous capture device, the CO 2 rich process stream is a pressurized process stream at a pressure which maintains the CO 2 in a solution state substantially within the CO 2 rich process stream, while in the electrodialysis unit, the CO 2 rich process is a buffered process stream having a pH ranging from about 3 to 4 while in the electrodialysis unit, and the capture solution is a buffered process stream having a pH ranging from about 8 to about 10 while in the electrodialysis unit.
