CO2 RECOVERY DEVICE, AND CO2 RECOVERY METHOD

A CO2 recovery system includes a CO2 absorber 18 that brings flue gas 11 containing CO2 into contact with a CO2 absorbent 17 and removes CO2 from the flue gas, an absorbent regenerator 20 that separates CO2 from a rich solution 19 that has absorbed CO2 and regenerates the CO2 absorbent as a lean sol...

Zusammenfassung:	A CO2 recovery system includes a CO2 absorber 18 that brings flue gas 11 containing CO2 into contact with a CO2 absorbent 17 and removes CO2 from the flue gas, an absorbent regenerator 20 that separates CO2 from a rich solution 19 that has absorbed CO2 and regenerates the CO2 absorbent as a lean solution, a gas discharge line L21 that discharges a CO2 entrained gas 28 discharged from a top portion of the absorbent regenerator 20, a reflux water drum 30 that is provided in the gas discharge line L21 and separates water in the CO2 entrained gas as reflux water 31, a separation-gas discharge line L22 that discharges the CO2 gas separated by the reflux water drum, a compressor 41 that is provided in the separation-gas discharge line L22 and compresses the separated CO2 gas, a condensate water drum 44 that is provided in the separation-gas line L22 and separates water in the separated CO2 gas as compressor condensate water, and a compressor-condensate water line L30 that is connected to the condensate water drum and supplies the compressor condensate water 43 separated from the condensate water drum as in-system supply water 43A or out-of-system supply water 43B.
