CO2 RECOVERY SYSTEM AND CO2 RECOVERY METHOD

摘要

A CO 2 recovery system includes an absorption apparatus that brings a CO 2 absorption liquid into contact with an exhaust gas treated by a pre-treatment apparatus so that CO 2 in the exhaust gas is absorbed into the CO 2 absorption liquid; a regeneration apparatus that separates CO 2 from the CO 2 absorption liquid; an absorption liquid circulation path that circulates the CO 2 absorption liquid between the absorption apparatus and the regeneration apparatus; and an impurity removal unit that removes impurities having a high concentration in the absorption liquid circulation path, in the absorption liquid circulation path and/or in the pre-treatment apparatus in advance.
