Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a refining method for gas wherein dirt of a tower itself in a refining process, and dirt of a next tower, and a heat exchanger, a tower tank or the like installed in an absorption liquid line of the next tower by splash of an absorption liquid from a first tower of absorption or splash of the absorption liquid from a second tower in addition to a heat exchanger, a tower tank or the like installed in a line of the absorption liquid through which the absorption liquid flowing out from the tower newly flows into the tower are suppressed. SOLUTION: In this method for refining coke oven gas or coal pyrolysis furnace gas by a plurality of absorption towers, contents are extracted outside a system from the power bottom of the first absorption tower.
