Patent abstract
In a wet-process gas treatment method of treating an acid gas by using at least two treating columns connected in series, a ratio of the concentration of an acid gas at an outlet to a concentration of the acid gas at an inlet of a first treating column is set higher than a ratio of the concentration of the acid gas at an outlet to the concentration of acid gas at an inlet of at least one of the other treating columns, thereby preventing deposits from forming in the interior of connecting pipes between the columns and in the interiors of the treating columns, to prevent the connecting pipes from being blocked.
