[Structure] The off-gas system of a pressure swing adsorption apparatus composed of a plurality of adsorption towers operated in a pressure swing adsorption step including adsorption, washing, desorption, pressure equalization, and pressure elevation steps, in off gas adsorption, pressure equalization, pressure elevation, and purge steps. It is a pressure swing adsorption device provided with an adsorption tower to be operated. During the adsorption step, weakly adsorbed components such as H 2 are recovered from the upper part of the adsorption tower,
During the cleaning process, the off-gas from the adsorption tower is recovered by the pressure equalization operation between the bottoms of the adsorption tower after adsorbing a strongly adsorbed component gas such as CO 2 which remains in the off-gas in the off-gas adsorption tower. Therefore, the recovery rate of this component gas is remarkably improved, and it is possible to recover two components.
