Patent ID: 8500886

Claim:
A carbon dioxide removal system comprising: a total heat exchanger having adsorption and desorption zones, the adsorption zone configured to receive, cool and dehumidify exhaust gas from a fossil-fuel burning furnace and produce a dehumidified exhaust gas; and a carbon dioxide adsorption rotor having adsorption and desorption zones, the adsorption zone of the carbon dioxide adsorption rotor configured to remove carbon dioxide from the dehumidified exhaust gas and produce a cleaned gas, which is then sent through the desorption zone of the total heat exchanger for desorption of moisture from the total heat exchanger before being exhausted to outside atmosphere, the desorption zone of the carbon dioxide adsorption rotor being desorbed of carbon dioxide using water vapor, and the desorption zone of the carbon dioxide adsorption rotor producing very humid carbon dioxide to be sent to a processing system such as for underground burial, the system configured such that the resultant gas after passage through the total heat exchanger is sent to a dehumidifying rotor, and then sent to the carbon dioxide adsorption rotor, and a portion of the resultant gas after passage through the dehumidifying rotor is sent to a purge zone of the carbon dioxide adsorption rotor, and is then heated and sent through the desorption zone of the carbon dioxide adsorption rotor.
