摘要： 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.

摘要： A method of operating a carbon dioxide recovering apparatus includes introducing flue gas into an absorbing tower, bringing the flue gas into contact with an absorbing solution, and discharging a first rich solution, which is then divided into second and third rich solutions. The second rich solution is heated using a lean solution from a releasing tower. The third rich solution is heated using steam from the releasing tower. The lean solution and the steam are generated in the releasing tower from the second and third rich solutions. The steam used to heat the third rich solution is separated, in a gas-liquid separator, into carbon dioxide and condensate water. The amount of condensate water formed in the gas-liquid separator is measured, and a flow dividing ratio between the second rich solution and the third rich solution is controlled based on a change in the amount of the condensate water.

摘要： A carbon dioxide capture system according to an embodiment includes an absorber, a stripper, and a heater. The absorber includes a first cleaning unit and a second cleaning unit. The first cleaning unit uses first cleaning liquid to clean combustion exhaust gas discharged from a carbon dioxide capturer and captures amine flowing together with the combustion exhaust gas. The second cleaning unit uses second cleaning liquid to clean the combustion exhaust gas discharged from the first cleaning unit and captures amine flowing together with the combustion exhaust gas. The heater heats the first cleaning liquid to a temperature higher than the temperature of an upper portion of the carbon dioxide capturer and of the second cleaning liquid.
