ABSTRACT:
The secondary purifier, composed of two cylindrical adsorbent beds and valving, is used to increase the oxygen concentration of the product gas comprising oxygen and argon from a zeolite molecular sieve concentrator. The oxygen purity of the gas is increased by selectively adsorbing and exhausting the argon component by the use of beds of small particle size (16.times.40 mesh) carbon molecular sieve. In a two step cycle, during step 1 of the cycle one bed receives high pressure 30 PSIA feed gas which pressurizes the bed and establishes a product oxygen flow, and the argon component of the air is removed by preferential adsorption in the carbon molecular sieve. Simultaneously, the high pressure gas in the other bed is vented to a lower pressure usually the ambient surroundings, and this depressurization serves to desorb the argon previously adsorbed during the high pressure phase of the cycle. In step 2 of the cycle the adsorbent beds exchange roles. This constant cycling results in a continuous product stream of very high purity oxygen (up to 99.6%). The separation is conducted at a temperature of 297.degree. K. The secondary purifier does not require a regenerative purge flow for efficient operation, which minimizes the feed gas consumption.
