    摘要： Disclosed is a method for enriching combustible gas, which suppresses the deterioration and pulverization of an adsorbent without extending a period for pressure equalization. The pressure equalization is effected by opening a pressure equalization passage opening/closing valve incorporated in a pressure equalization passage, after completion of adsorption in a first adsorption tower and after completion of desorption in a second adsorption tower connected to the first adsorption tower via the pressure equalization passage.

    摘要： According the present invention, an oxygen enriched gas is generated by adsorbing and removing nitrogen gas from air with an oxygen concentrating apparatus which conducts the steps of (1) pressurizing one of the adsorption cylinders by directing the compressed air; (2) removing the oxygen enriched gas from said one of the adsorption cylinders to the output conduit; (3) reducing the pressure in said one of the adsorption cylinders by directing the oxygen enriched gas into one of the other adsorption cylinders to increase the pressure in the one of the other adsorption cylinders; (4) evacuating the internal gas out of said one of the adsorption cylinders; and (5) increasing the pressure in said one of the adsorption cylinders by directing the oxygen enriched gas into said one of the adsorption cylinders from one of the other adsorption cylinders in which the pressure is decreased in step (3).

    摘要： A low void pressure swing adsorption system wherein flow movement and pressure pulse are influenced from the same source comprised of at least one hermetically sealed vessel containing an adsorbent bed with an inlet coupled to the adsorbent bed by way of an inlet header and an outlet coupled to the adsorbent bed by way of an outlet header. Void volume of the inlet and outlet headers can be limited to less than 20% of the adsorbent bed volume, preferably to less than 10%, and most preferably to less than 5%, by mounting high pressure source(s) and/or low pressure sink(s) proximate to, or nearly proximate to, the adsorbent bed/vessel. Low void volumes and reduced cycle times may be achieved in all bed configurations, including flat header beds, segmented beds, and vertical beds. Radial beds may be configured so that the void volume of the inlet and outlet headers is less than 50% of the volume of the radial adsorbent bed, preferably to less than 20%, and most preferably to less than 10%.
