Abstract:
A system for capturing carbon dioxide is provided including a feed line transporting an exhaust gas, a first separator, a first compressor, a first membrane, a first ejector, a second separator, a second compressor, and a carbon dioxide storage tank. The first membrane is configured to filter the exhaust gas into a retentate stream of exhaust gas and a permeate stream of exhaust gas. The permeate stream of exhaust gas includes a larger amount of carbon dioxide than the retentate stream. The first ejector is configured to compress the permeate stream. The second compressor is configured to further compress the exhaust gas received from the second separator. The carbon dioxide storage tank is configured to receive the exhaust gas from the second compressor. A second membrane can be on the retentate stream of the first membrane, where a second ejector is on the permeate side of the second membrane.
