Abstract

Provided is a method for producing oxygen by pressure swing adsorption, comprising one or more predetermined treatment steps. For each predetermined treatment step, the predetermined treatment is performed in each tower in the oxygen generating system and a plurality of adjacent towers flanking each of the two sides of the tower. The method facilitates the increase of the oxygen recovery rate in oxygen production by pressure swing adsorption.
