Abstract

PURPOSE: To obtain the concentrated O2 in a good yield by a method wherein compressed air is introduced into a tower packed with a N2 adsorbing agent to adsorb N2 under pressure and other regenerating adsorbing tower is evacuated by the nagative pressure generated by introducing pressurized air into an ejector in a regeneration procedure of the adsorbing agent to carry out the regeneration of the adsorbing agent effectively.
CONSTITUTION: In the titled method repeating the procedure for introducing compressed air into the adsorbing towers 1, 2 packed with the N2 adsorbing agent from a compressor 4 to concentrate O2 in air and the procedure for regenerating the adsorbing agent by evacuating the adsorbing tower, for example, in the desorption and regeneration produre of the adsorbing tower 1, the pressurized air in the tower is introduced into an ejector 16 to be opened into the atmosphere by operating a valve and the negative pressure generated by the ejector is utilized, for example, in the vacuum regeneration of the adsorbing tower 2 during the vacuum regeneration procedure. The above operations are carried out by switching a predetermined valve respectively. Thereby, a vacuum generator or the like of a conventional method is not required and the regeneration of the adsorbing tower is carried out effectively as well as the concn. of oxygen is carried out inexpensively.
