CO2 RECOVERY DEVICE AND CO2 RECOVERY METHOD

摘要

A CO 2 recovery apparatus includes a desulfurization tower which includes a desulfurization unit and a cooling unit, an absorption tower which includes a CO 2 absorption unit and an acid washing unit, a regeneration tower, and an acid water production device configured to produce acid water by causing exhaust gas yet to be introduced into the desulfurization to come into contact with water. In the CO 2 recovery apparatus, the water to be come in contact with the exhaust gas is condensed water that is generated in the desulfurization tower, the absorption tower, or the regeneration tower.
