Abstract
Upon a reduction of the production flow rate, there is added to the cycle, at an extreme pressure PM and/or Pm of the cycle substantially different from atmospheric pressure, an idle time in the course of which the adsorber (1A, 1B) is isolated. The process is used in trans-atmospheric cycles for the production of oxygen from atmospheric air.
