Abstract

In one embodiment, a carbon dioxide separating and capturing system includes an absorption tower to allow a gas containing carbon dioxide to contact with an absorption liquid and discharge a first rich liquid which is the absorption liquid having absorbed the carbon dioxide, and a regeneration tower to cause the absorption liquid to release a gas containing the carbon dioxide and discharge a lean liquid whose carbon dioxide concentration is lower than that of the rich liquid. The system further includes a reboiler to heat the absorption liquid in the regeneration tower by using steam, and a flow divider to divide the first rich liquid into second and third rich liquids. The system further includes a first heat exchanger to heat the second rich liquid by using the lean liquid, and a second heat exchanger to heat the third rich liquid by using water discharged from the reboiler.
