摘要：
The CO2 recovery apparatus is provided with a CO2 absorption portion for absorbing CO2 in a CO2-containing exhaust gas by a CO2 absorbing liquid, a water washing portion provided on the upper portion side of the CO2 absorption portion so as to cool a CO2-removed exhaust gas and also recover the accompanying CO2 absorbing liquid, a washing liquid circulation line for directly circulating a washing liquid containing the CO2 absorbing liquid recovered in the water washing portion, an extraction line for extracting part of the washing liquid containing the CO2 absorbing liquid as an extracted liquid from the washing liquid circulation line, a concentration portion for separating a gas component (water vapor) from the extracted liquid while concentrating the CO2 absorbing liquid, and a concentrated liquid feed line for feeding a concentrated liquid concentrated in the concentration portion to the side of an absorbing liquid regeneration tower.
