(57) A CO, separation/recover method in cement production exhaust gas has a step of harmful component removal that removes an acidic component and a harmful component from exhaust gas discharged from a cement production facility; and a step of CO, separation and recover that separates and recovers CO, by bringing the exhaust gas from which the acidic component and the harmful component are removed into contact with a CO, absorption material, so that the acidic component and the harmful component are removed before separating and recovering CO₂, resulting in deterioration of the absorbing ability of the CO, absorption material being suppressed; and the cement production exhaust gas can be appropriately disposed.
