Title:
圧力変動吸着式ガス分離方法及びガス分離装置
Document Type and Number:
Japanese Patent JP6876678
Kind Code:
B2
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 g0 is fed to one adsorption vessel 11 of an adsorbing device 10 and a permeated gas g1 is sent out. A pressure of the other the adsorption vessels 12 is made lower than a pressure during adsorption and a desorbed gas g2 is sent out. In accordance with an operating cycle of the adsorbing device 10 or according to a condition of the raw material gas g0 or the like, one of the permeated gas g1 and the desorbed gas g2 that has a lower concentration of a priority removal object gas component than the raw material gas g0 is provided as a return gas to the adsorbing device 10, the priority removal object gas component being a gas component to be preferentially removed.
