<p>PURPOSE: To economically separate weakly adsorptive components by a simple method by alternately operating two adsorbers and partially executing the sepn. of untreated gases under reduced pressure when the max. adsorption pressure is attained. CONSTITUTION: Air is delivered from a valve B1 to the adsorber B by an air blower. Since the air flows from the adsorber A through a valve AB1 into the adsorber B, the pressure of the adsorber B increases and the pressure of the adsorber A drops. The adsorber B is then filled with the gas of a storage device R from a volume control valve AB3 and a valve B3. When the adsorber A attains the min. pressure, the air supply from a valve B1 and the product gases from a valve B3 and a valve AB2 are introduced into the storage device R until the final pressure is attained in the adsorber B and the storage device R. A similar cycle is then executed in the form of exchanging the adsorbers A and B. The weakly adsorptitve component like oxygen in the air is separated and the higher concn. can be attained by the method described above.</p> |
