PROBLEM TO BE SOLVED: To suppress a diffusion of an absorbent component.SOLUTION: According to the present embodiment, a carbon dioxide separation recovery system includes: an absorption tower which receives an introduction of a gas containing carbon dioxide, brings the gas into contact with an absorbent that absorbs carbon dioxide, and discharges a rich liquid that has absorbed carbon dioxide; a regeneration tower that heats the absorbent, emits a gas containing carbon dioxide from the absorbent, and discharges a lean liquid which has a lower carbon dioxide concentration than the rich liquid; a regeneration heat exchanger that heats the rich liquid supplied from the absorption tower into the regeneration tower by using the lean liquid supplied from the regeneration tower into the absorption tower; a first cleaning part that brings the gas discharged from the absorption tower or the regeneration tower into contact with the cleaning liquid to make the cleaning liquid recover an absorbent component in the gas; and a first concentrator that concentrates the absorbent that has recovered the absorbent component. |
