Abstract
A filtration membrane device which uses a filter to collect solid contents remaining in a branched lean solution cleans the filter by using a low-concentration COabsorption liquid circulating within the system as cleaning water (containing the absorption liquid); rough cleaning, which returns the low-concentration COabsorption liquid used for cleaning to a lean solution supply line, is performed; the filter is finish-cleaned by cleaning water from outside the system which does not include the COabsorption liquid; the COabsorption liquid which is adhered to the solid contents is washed and removed; finish-cleaning water which includes the COabsorption liquid is returned to the lean solution supply line the moisture content within the system is maintained at a prescribed value by adjusting the water balance in an absorption tower and the concentration of the COabsorption liquid which circulates within the system is kept at a prescribed concentration.
