Abstract
An apparatus for capturing a target component from a gas including a rotating packed bed and a packed bed is provided. 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 communicated with the second absorbent inlet to form an absorbent flow path sequentially passes through the rotating packed bed and the packed bed. The second gas outlet is communicated with the first gas inlet to form a gas flow path sequentially passes through the packed bed and the rotating packed bed.
