摘要： According to embodiment, a carbon dioxide capturing system cools a regenerator discharge gas discharged from a regenerator 5 containing carbon dioxide by a cooling unit 8, and then sends the gas to a cleaner 9. The cleaner 9 receives condensed water generated from the regenerator discharge gas cooled by the cooler 9, and a gaseous cooled regenerator discharge gas, and cleans the cooled regenerator discharge gas by a cleaning liquid. The cleaner 9 has a first liquid reservoir 9b configured to store the condensed water, and a second liquid reservoir 9c configured to store the cleaning liquid having cleaned the cooled regenerator discharge gas.

摘要： A carbon dioxide capture system according to the embodiment includes: a carbon dioxide capturer configured to cause a carbon dioxide contained in a combustion exhaust gas into an absorbing liquid containing an amine; a first washer configured to wash the combustion exhaust gas from the carbon dioxide capturer with a mist of a first cleaning liquid sprayed by a spray to capture the amine contained in the combustion exhaust gas; and a cleaning liquid mist capturer configured to capture the mist of the first cleaning liquid contained in the combustion exhaust gas from the first washer. The first washer has a receiver arranged below the spray, and a washing-capturing space arranged between the spray and the receiver. In the washing-capturing space, the mist of the first cleaning liquid comes into gas-liquid contact with the combustion exhaust gas while freely dropping.

摘要： 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.
