A CO2 recovery apparatus includes a desulfurization tower which includes a desulfurization unit and a cooling unit, an absorption tower which includes a CO2 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 CO2 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.
