Acidic gas recovery apparatus and acidic gas recovery method

The present embodiments provide an acidic gas recovery apparatus or method capable of efficiently reducing emission of 5 amine to the environment. In the embodiment, an acidic gas recovery apparatus 10A comprises: an acidic gas-absorber 11a; a regeneration tower 12; a gas-cleaner 11b; a cleaning liquid drawing-out line L23; an absorbing liquid drawing-out line L21; and an acidic component-remover 13A. The cleaning water 27c 10 from the cleaning liquid drawing-out line L23 and a purified lean solution 23C from the absorbing liquid drawing-out line L21 are supplied to the acidic component-remover 13A. The acidic component-remover 13A comprises a cathode 53, an anode 54, an absorbing liquid-purification compartment 57 for removing 15 acidic components from the objective lean solution 23B, and cleaning liquid compartments 58-1 and 58-2. The cleaning water 27 is supplied to the cleaning liquid compartments.
