Zusammenfassung:A carbon dioxide capture system according to an embodiment includes an absorber, a stripper, and a heater. The absorber includes a first cleaning unit and a second cleaning unit. The first cleaning unit uses first cleaning liquid to clean combustion exhaust gas discharged from a carbon dioxide capturer and captures amine flowing together with the combustion exhaust gas. The second cleaning unit uses second cleaning liquid to clean the combustion exhaust gas discharged from the first cleaning unit and captures amine flowing together with the combustion exhaust gas. The heater heats the first cleaning liquid to a temperature higher than the temperature of an upper portion of the carbon dioxide capturer and of the second cleaning liquid.
