Summary:An absorber (20) of a carbon dioxide capture system according to an embodiment includes: a release region (22) for releasing carbon dioxide from an absorbing liquid (5) supplied from a stripper; and a second gas-liquid contact unit (23) to which carbon dioxide released in the release region is supplied together with exhaust gas discharged from a first gas-liquid contact unit (21) . The absorbing liquid having released the carbon dioxide therefrom in the release region is supplied to the second gas-liquid contact unit by an absorbing liquid supply device (27). The absorbing liquid having passed through the second gas-liquid contact unit is guided to the first gas-liquid contact unit while bypassing the release region. The second gas-liquid contact unit brings the exhaust gas and the absorbing gas into contact with each other so as to cause the carbon dioxide contained in the exhaust gas to be absorbed in the absorbing liquid.
