摘要： In accordance with an embodiment, a carbon dioxide capturing device includes an absorption tower, a regeneration tower, and a cooling unit. A gas containing carbon dioxide and a lean liquid is introduced to the absorption tower which brings the gas and the lean liquid into contact with each other to generate a rich liquid. The regeneration tower generates a lean liquid by diffusing vapor containing carbon dioxide from the rich liquid from the absorption tower, and then returns the lean liquid to the absorption tower. The cooling unit cools at least one of the gas, the lean liquid, and the rich liquid. The cooling unit includes first and second coolers connected in series to each other, by first and second cooling mediums, respectively. The first cooling medium is generated outside the device without using power for cooling in the device. The first cooler is located upstream of the second cooler.
