Abstract

A process for regulating a unit for the production of oxygen from atmospheric air comprising N adsorbers (, N being = or >2, each according to a PSA, VSA or VPSA adsorption cycle with an offset of a phase time, the regulation process including determining a value of differential pressure characteristic of a step of the adsorption cycle for each adsorber, calculating the difference between the values of differential pressures characteristic of the various adsorbers, comparing this difference with a target value and, in the event of a dissimilarity being noted, correcting by modification of the transfer of at least one oxygen-rich gas stream between adsorbers or optionally between adsorber and storage tank.
