CO2 recovery system and CO2 recovery method

Abstract

A CO2 recovery system includes: a combustion facility; a CO2 absorption tower that brings an exhaust gas containing CO2, which is discharged from the combustion facility and introduced into the CO2 absorption tower, into contact with a CO2 absorption liquid to remove the CO2 from the exhaust gas; and a decarbonated gas introduction line that is connected to the CO2 absorption tower and the combustion facility and allows at least a portion of a decarbonated gas, which is the exhaust gas from which the CO2 has been removed in the CO2 absorption tower, to be introduced into the combustion facility.
