Abstract
In one embodiment, a carbon dioxide capturing system includes an absorption tower to bring a gas containing carbon dioxide into contact with an absorbing liquid to discharge the absorbing liquid which has absorbed the carbon dioxide and discharge the gas whose carbon dioxide concentration is reduced. The system includes a regeneration tower to release the carbon dioxide from the absorbing liquid to discharge the absorbing liquid whose carbon dioxide concentration is reduced and discharge a gas containing the carbon dioxide. The system includes a first absorbing liquid component washing apparatus to cool the gas which is discharged from the absorption or regeneration tower and has passed through an absorption or regeneration tower condenser to condense or sublime an absorbing liquid component in the gas and remove a liquid or solid product generated by the condensation or sublimation of the absorbing liquid component by using a washing liquid.
