A carbon dioxide capturing system according to an embodiment is provided with a reboiler which heats an absorption liquid in a regeneration tower with a heated steam, and condenses the heated steam to generate a downstream side condensed water. The heated steam is supplied to the reboiler by an upstream side line. The downstream side condensed water is discharged from the reboiler by a downstream side line. A branched line branches from the upstream side line. The heated steam supplied to the branched line is cooled and condensed by an upstream side cooler, and an upstream side condensed water is generated. A physical quantity of an absorption liquid component in the upstream side condensed water and a physical quantity of an absorption liquid component in the downstream side condensed water are measured by a physical quantity measurement device.

Carbon dioxide capturing system and operation method of carbon dioxide capturing system

A carbon dioxide capture system includes: a washing unit which uses cleaning water to clean absorption unit exhaust gas or stripping unit exhaust gas; and a gas-liquid separation device which allows condensed water generated by cooling washing unit exhaust gas to be separated from the washing unit exhaust gas. The condensed water is mixed into the cleaning water by a condensed water line. If the amount of the cleaning water becomes more than a predetermined amount, the cleaning water is mixed into an absorbing liquid by a cleaning water line. A controller controls a condensed water valve.
