Abstract: Provided herein is a method for absorbing CO2 from a gas mixture. The method includes using an apparatus comprised of a first RPB unit and a second RPB unit. The first RPB unit and the second RPB unit are arranged to absorb CO2 in a first gas stream and a second gas stream, respectively. A liquid CO2-absorbent is supplied sequentially passing through the first RPB unit and the second RPB unit to absorb CO2 in the first gas stream and the second gas stream. The liquid CO2-absorbent is regenerated to produce a regenerated CO2-absorbent. The regenerated CO2-absorbent is transported to the first RPB unit.

Abstract: Provided is an apparatus for capturing a target component from a gas including a rotating packed bed and a packed bed. The rotating packed bed has a first absorbent inlet, a first absorbent outlet, a first gas inlet and a first gas outlet. The packed bed has a second absorbent inlet, a second absorbent outlet, a second gas inlet and a second gas outlet. The first absorbent outlet is in connection with the second absorbent inlet to form an absorbent flow path that sequentially passes through the rotating packed bed and the packed bed. The second gas outlet is in connection with the first gas inlet to form a gas flow path that sequentially passes through the packed bed and the rotating packed bed.

Abstract: Provided herein is an apparatus for absorbing a component from a gas mixture. The apparatus includes a first rotating packed (RPB) and a second RPB. The first RPB and the second RPB are arranged to respectively process a first gas stream and a second gas stream containing the component. A liquid absorbent sequentially passes through the first RPB and the second RPB to absorb the component in the first gas stream and a second gas stream.

Abstract: The present invention discloses a carbon dioxide (CO2) absorbing agent, a CO2 capture system and a method of slowing down the degradation of the CO2 absorbing agent. More specifically, by adding additives of inorganic salts to the CO2 absorbing agent to act as an oxygen inhibitor, the dissolved oxygen value thereof would be decreased so as to slow down the degradation of the CO2 absorbing agent.
