Abstract

PURPOSE: To efficiently separate oxygen in air by using two towers in a series adsorption process and two towers in a regeneration process out of four towers packed with a selective nitrogen adsorbent and by switch-controlling them in order according to a predetermined method.
CONSTITUTION: When towers 1, 2 are used as series adsorption towers and towers 3, 4 as regeneration towers, cooled and dried air of 2W4kg/cm2 is press.-fed into tower 1 from the lower part through piping 12, reaches tower 2 through piping 15 to raise the oxygen concn. to 95.3W95.6%, and enters product O2 tank 10 through valve 2A and pipe 14. During this time, towers 3, 4 are used in a regeneration process, and by closing valves 4A, 4B, 4C, opening valves 4D, 5A, and evacuating tower 4 to below 1/4 atm with pump 5 adsorbed N2 is released into the air. In tower 3 the above-mentioned preceding stage regeneration is finished, and by allowing part of product O2 to flow backward from valve 3A tower 3 is kept under a press. of 0.5kg/cm2. After passage of a preset time the towers are switch-controlled in order so that towers 2, 3 are used as series adsorption towers and towers 4, 1 as regeneration towers. Since one tower of the highest N2 adsorption capacity is used as an O2 purification final tower, O2 purification can be performed efficiently.
