Provided are a carbon dioxide capture system capable of reducing the amount of amine released into the atmosphere, and a method for operating the carbon dioxide capture system. A carbon dioxide capture system according to the embodiment includes: a carbon dioxide capture configured to cause a carbon dioxide contained in a combustion exhaust gas into an absorbing liquid containing an amine; a firstwasher configured to wash the combustion exhaust gas from the carbon dioxide capture with a mist of a first cleaning liquid sprayed by a spray to capture the amine contained in the combustion exhaustgas; and a cleaning liquid mist capture configured to capture the mist of the first cleaning liquid contained in the combustion exhaust gas from the first washer. 本发明提供能够降低胺向大气中的放出量的二氧化碳回收系统及其运转方法。基于实施方式的二氧化碳回收系统具备二氧化碳回收部，使燃烧废气中含有的二氧化碳吸收到含有胺的吸收液中；和第1清洗部，将从二氧化碳回收部排出的燃烧废气用喷射器中喷射的第1清洗液的雾进行清洗，从而将燃烧废气中伴随的胺回收。此外，二氧化碳回收系统具备清洗液雾回收部，将从第1清洗部排出的燃烧废气中伴随的第1清洗液的雾进行回收。
