Abstract

PURPOSE:To prevent the reduction of adsorbed amount of N2 due to the adsorption of moisture on zeolite by providing packed beds in the order of activated carbon, activated alumina and zeolite from the feed side of air as a raw material and performing a pressure fluctuation adsorption method in the packed bed having such three-layer structure. CONSTITUTION:The air a raw material, is fed to an adsorption tower 1 under pressurization with a blower 10. The air is passed in the order of activated carbon, activated alumina and zeolite; water is adsorbed by activated carbon and activated alumina; N2 is adsorbed by zeolite; and concentrated O2 is flowed out and stored in a tank 14. After finishing the adsorbing process, the adsorption tower 1 is subjected to pressure equalization together with an adsorption tower 2 and furthermore decompressed with a vacuum pump 11 to desorb the adsorbed gas. Thus two adsorption towers 1, 2 are successively changed over and used.
