To provide a CO 2 recovery system and a recovery method for moisture containing CO 2 gas that enable to recover condensed water contained in CO 2 gas without discharging the condensed water to outside to efficiently use an absorbent contained in the condensed water, and enables to recover heat emitted from a CO 2 compressor system to effectively use the heat. A CO 2 recovery system 10A has a CO 2 recovery unit 11, a compression unit 12, and a condensed-water supply line 65A that supplies condensed water 64 to an absorbent regenerator 14. The CO 2 recovery unit 11 includes a CO 2 absorber 13 and the absorbent regenerator 14. The compression unit 12 has a first compressor 61-1 to an nth compressor 61-n that compress CO 2 gas 56 emitted from the absorbent regenerator 14, a first separator 63-1 to an nth separator 63-n that reduce moisture in the CO 2 gas 56, and a first heat exchanger 66-1 that performs heat exchange between the CO 2 gas 56 emitted from the first compressor and the condensed water 64 emitted from the first separator 63-1. |
