摘要： To further reduce the concentrations of basic amine compounds remaining in decarbonated flue gas.
A CO 2 recovery system includes an absorber 2 and a regenerator 3. The absorber 2 includes a CO 2 absorbing section 21 and a water-washing section 22. The CO 2 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 CO 2 in the flue gas 101. The water-washing section 22 allows the decarbonated flue gas 101A in which the amount of CO 2 has been reduced in the CO 2 absorbing section 21 to come into contact with circulating wash water 104 and to be washed with the wash water 104 so that the amounts of the basic amine compounds entrained in the decarbonated flue gas 101A are reduced. The regenerator 3 releases CO 2 from the basic amine compound absorbent 103 the CO 2 absorbed therein. The CO 2 recovery system further includes a concentrating unit 24 for concentrating the wash water 104 from the water-washing section 22. Condensed water generated during concentration is returned to the water-washing section 22.摘要翻译： 祖weiterer减少残留脱二氧化碳的烟道气中碱性胺化合物的浓度。 甲CO 2回收系统包括在吸收器2和一个再生器3吸收体2包括CO 2吸收部21和水洗部22的CO 2吸收部21允许烟道气101，以与碱性胺接触 化合物吸收103如此做了碱性胺化合物吸收103中吸收的CO 2的烟道气101的水洗部22允许该脱二氧化碳的烟道气在101A哪CO 2的量已在吸收部21向CO 2减少了在 成与循环洗涤水和104以与洗涤水104进行清洗，以便DASS死在脱二氧化碳的烟道气夹带101A碱性胺化合物的量减少接触。 从碱性胺化合物吸收103。其中所吸收的CO 2的再生器3释放的CO 2。 的CO 2回收系统包括进一步浓缩单元24，用于从水洗部浓度期间产生22的冷凝水返回到水洗部22日浓缩的洗涤水104
