摘要： An air pollution control system includes CO2 absorber that removes CO2, and an absorbent regenerator that releases CO2 from the amine absorbent. The CO2 absorber is equipped with a CO2 absorption unit that absorbs CO2 in the flue gas by the amine absorbent (lean solution), and a water-repellent filter unit that is provided on an upper part (gas flow downstream) side of the CO2 absorption unit and collects the mist amine absorbent accompanied by the CO2-free flue gas. The mist amine accompanied by the CO2-free flue gas is collected.
