ABSTRACT:
The process comprises a regeneration phase including a co-current depressurization step, in order to participate in the repressurization of another adsorber, a countercurrent depressurization down to the low pressure of the cycle without gas intake, and then a countercurrent elution step at the low pressure of the cycle with oxygen taken off from production. The cycle time does not exceed 20 seconds. The process is particularly application to the production of oxygen having a purity greater than 90% with flow rates of 2 to 6 liters/minute for oxygenotherapy.
