摘要： To further reduce the concentrations of basic amine compounds remaining in decarbonated flue gas. A CO 2 recovery system includes an absorber 2 and a regenerator 3. The absorber 2 includes a CO 2 absorbing section 21 and at least one water-washing section 22. The CO 2 absorbing section 21 allows flue gas 101 to come into contact with a basic amine compound absorbent 103 so that the basic amine compound absorbent 103 absorbs CO 2 in the flue gas 101. The at least one water-washing section 22 allows the decarbonated flue gas 101A in which the amount of CO 2 has been reduced in the CO 2 absorbing section 21 to come into contact with wash water 104A and 104B to reduce the amounts of the basic amine compounds entrained in the decarbonated flue gas 101A. The regenerator 3 releases the CO 2 from the basic amine compound absorbent 103 containing CO 2 absorbed therein. This CO 2 recovery system further includes an absorbent-treating section 23 disposed downstream of the at least one water-washing section 22 through which the decarbonated flue gas 101A flows. The absorbent-treating section 23 allows the decarbonated flue gas 101A to come into contact with circulating acidic water 105 to further reduce the amounts of the basic amine compounds entrained in the decarbonated flue gas 101A.

摘要： 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 CO 2 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.
