Abstract

A reclaiming apparatus 106 includes: a sealed container 106a that is an absorbent reservoir for storing therein a part of an absorbent that has absorbed CO2 in flue gas, and a heater that heats the absorbent stored in the sealed container 106a. The reclaiming apparatus 106 distributes a part of the absorbent stored in the sealed container 106a, and brings the distributed absorbent into counter-current contact with steam. Because a part of the absorbent stored in the absorbent reservoir is brought into counter-current contact with the steam, absorbent component contained therein becomes volatilized, and is separated from depleted materials. In this manner, the absorbent component can be extracted from the depleted materials, and a loss of the absorbent can be reduced.
