摘要： The present invention comprises a filtration membrane device (13) which uses a filter (12) to collect solid contents (11) remaining in a branched lean solution (1005B-1). With respect to the filtration membrane device (13) when the filter (12) has been used to collect the solid contents (11): the filter (12) is cleaned using a low-concentration CO 2 absorption liquid as cleaning water (containing the absorption liquid) (16A), said low-concentration CO 2 absorption liquid circulating within a system; rough cleaning, which returns the low-concentration CO 2 absorption liquid used for cleaning to a lean solution supply line (L 13 ), is performed; the filter (12) is finish-cleaned by cleaning water (21) which does not include the CO 2 absorption liquid and which is from outside the system; the CO 2 absorption liquid which is adhered to the solid contents (11) is washed and removed; finish-cleaning water (21a) which includes the CO 2 absorption liquid is returned to the lean solution supply line (L 13 ); the moisture content within the system is maintained at a prescribed value by adjusting the water balance in an absorption tower (1004); and the concentration of the CO 2 absorption liquid which circulates within the system is kept at a prescribed concentration.
