Abstract: In order to reduce energy consumed for waste water treatment, in a scrubber (10), an exhaust gas (g1) is purified into a purified gas (g2) by bringing SO 2 contained in the exhaust gas (g1) into contact with cleaning seawater (a1) and SO 2 -absorbed cleaning seawater is discharged as waste water (a2). Then, a flow rate and a concentration of SO 2 of the exhaust gas and a concentration of SO 2 of the purified gas are measured. These measurement values are used as a basis to calculate an amount of HSO 3 - obtained by being absorbed into the cleaning seawater, and an amount of dilution seawater (a3) in accordance with this calculation result is supplied to the waste water.

Abstract: Provided are a CO 2 recovery unit and a CO 2 recovery method which enable stable operation to continue even if an operation condition has changed. This CO 2 recovery unit (1) is equipped with: a CO 2 -absorber (14) that causes CO 2 included in flue gas (11A) to be absorbed into a CO 2 -absorbing solution (13); a CO 2 -regenerator (15) which regenerates the CO 2 -absorbing solution (13) by heating; and a CO 2 recovery amount control unit (111) which calculates a computed target value for the CO 2 recovery amount and a computed target value for the CO 2 recovery rate on the basis of a set value for the CO 2 recovery rate, actual measured values of the CO 2 concentration, gas flow rate, and temperature of the flue gas (11A), and maximum values for the CO 2 recovery amounts in the CO 2 -absorber (14) and the CO 2 -regenerator (15). On the basis of the set value for the CO 2 recovery rate or the computed target value for the CO 2 recovery rate, the CO 2 recovery amount control unit (111) controls: the amount of the CO 2 -absorbing solution (13) supplied to the CO 2 -absorber (14); the amount of the CO 2 -absorbing solution (13) supplied to the CO 2 -regenerator (15); and the amount of saturated steam (S) supplied to a regeneration heater (31) of the CO 2 -regenerator (15).
