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 a 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 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 circulating wash water 104 and to be washed with the wash water 104 so that the amounts of the basic amine compounds entrained in the decarbonated flue gas 101A are reduced. The regenerator 3 releases CO 2 from the basic amine compound absorbent 103 the CO 2 absorbed therein. The CO 2 recovery system further includes a concentrating unit 24 for concentrating the wash water 104 from the water-washing section 22. Condensed water generated during concentration is returned to the water-washing section 22.
