Patent ID: 8114191

Claim:
A system for capturing carbon dioxide including: a feed line transporting an exhaust gas; a first separator configured to draw liquid off the exhaust gas; a first compressor configured to compress the exhaust gas; a first membrane configured to filter the exhaust gas received from the first compressor into a retentate stream of exhaust gas and a permeate stream of exhaust gas wherein the permeate stream of exhaust gas includes a larger amount of carbon dioxide than the retentate stream of exhaust gas; a first ejector, downstream of the first compressor, configured to compress the permeate stream of exhaust gas; a second separator configured to draw liquid off the exhaust gas received from the first ejector; a second compressor, downstream of the first ejector, configured to further compress the exhaust gas received from the second separator; and a carbon dioxide storage tank configured to receive a portion of the exhaust gas from the second compressor.
