Abstract
It is an objective of the present invention to provide a gas separation method by which a removal performance to remove a removal object gas component and a recovery rate to recover a recovery object gas component can be satisfied at the same time, and furthermore, a generation efficiency of a product gas can be improved. A raw material gas gis fed to one adsorption vesselof an adsorbing deviceand a permeated gas gis sent out. A pressure of the other the adsorption vesselsis made lower than a pressure during adsorption and a desorbed gas gis sent out. In accordance with an operating cycle of the adsorbing deviceor according to a condition of the raw material gas gor the like, one of the permeated gas gand the desorbed gas gthat has a lower concentration of a priority removal object gas component than the raw material gas gis provided as a return gas to the adsorbing device, the priority removal object gas component being a gas component to be preferentially removed.
