Description

The pressure swing adsorption method was employed to concentrate oxygen in the air using zeolite adsorbent. Nitrogen adsorption behaviour was studied, using vacuum desorption and purge desorption. A part of the oxygen produced served as purge gas in the operation. The effects of operating factors related to the purge oxygen, such as desorption pressure, amount of purge gas, flow rate and temperature, were investigated to improve the efficiency of nitrogen desorption without oxygen leakage from the adsorption bed.<BR>The amount of desorbed nitrogen increased with reducing desorption pressure.<BR>The amount of purge oxygen increased with decreasing desorption pressure and temperature. A larger amount of nitrogen was found to desorb by the vacuum purge method, resulting in high-efficiency nitrogen desorption achieved in operating the adsorption regenerator.
