Abstract
In one embodiment, a carbon dioxide capturing system includes an absorber to discharge an absorption liquid having absorbed carbon dioxide, a regenerator to discharge the absorption liquid having released the carbon dioxide, a first line to introduce the absorption liquid discharged from the absorber to the regenerator, a second line to introduce the absorption liquid discharged from the regenerator to the absorber, and a heat exchanger to exchange heat between absorption liquids flowing in the first and second lines. The system further includes a bypass line to branch from the first line between the absorber and the heat exchanger and introduce the absorption liquid to the regenerator without passing through the heat exchanger, a valve on the bypass line, an instrument to measure a value indicating a state of the regenerator, and a controller to control a degree of opening of the valve based on the measured value.
