    摘要： A CO2 recovery device includes: a CO2 absorption unit for absorbing CO2 in a CO2-containing flue gas, by a CO2 absorbent; a washing unit for cooling a CO2-removed flue gas and recovering the accompanying CO2 absorbent; a circulation line for directly circulating wash water; an extraction line for extracting a part of the wash water containing the CO2 absorbent as an extracted fluid; a first gas-liquid separation unit for separating a gas component from the extracted fluid; a concentration unit for concentrating the CO2 absorbent contained in the extracted fluid and separating the gas component; a concentrated fluid return line through which a concentrated fluid returns to the CO2 absorption unit provided below the washing unit; and a gas inlet line through which the separated gas component is introduced into an absorber.

    摘要： [Object] To further reduce the concentrations of basic amine compounds remaining in decarbonated flue gas.[Means of Solution] A CO2 recovery system includes an absorber 2 and a regenerator 3. The absorber 2 includes a CO2 absorbing section 21 and at least one water-washing section 22. The CO2 absorbing section 21 allows flue gas 101 to come into contact with a basic amine compound absorbent 103 so that the basic amine compound absorbent 103 absorbs CO2 in the flue gas 101. The at least one water-washing section 22 allows the decarbonated flue gas 101A in which the amount of CO2 has been reduced in the CO2 absorbing section 21 to come into contact with wash water 104A and 104B to reduce the amounts of the basic amine compounds entrained in the decarbonated flue gas 101A. The regenerator 3 releases the CO2 from the basic amine compound absorbent 103 containing CO2 absorbed therein. This CO2 recovery system further includes an absorbent-treating section 23 disposed downstream of the at least one water-washing section 22 through which the decarbonated flue gas 101A flows. The absorbent-treating section 23 allows the decarbonated flue gas 101A to come into contact with circulating acidic water 105 to further reduce the amounts of the basic amine compounds entrained in the decarbonated flue gas 101A.
