초록

A process for separating enriched oxygen and argon from air through pressure swing adorption by using an adsorbent which is capable of selectively adsorbing nitrogen. Product gas is recovered from one adsorption column in which the adsorption step has already been completed by moving the gas to another adsorption column in which regeneration of the adsorbent by pressurization with the product gas has already been completed on the basis of pressure equalization. In this case, at the same time as the gas is being moved from the feed end of one column to th...

청구항

A process for separating oxygen from a feed gas containing at least oxygen, nitrogen and argon through pressure swing adsorption utilizing three adsorption columns containing an adsorbent capable of selective adsorption of nitrogen comprising: (i) introducing said feed gas into a first adsorption column, in which step (viii) was previously completed, from its feed end to pressurize the column, thereby absorbing the nitrogen in the feed gas and obtaining a product gas; (ii) introducing a portion of the product gas obtained in step (i) into a second column...
