Method of adjusting an oxygen production unit by comparing the differential pressures characteristic of the different adsorbers

摘要

Method of adjusting an oxygen production unit from atmospheric air comprising N adsorbers (1, i, N), N being = or> 2, each following an adsorption cycle of the PSA, VSA or type VPSA with a phase time shift, said adjustment method comprising determining a differential pressure value characteristic of a step of the adsorption cycle for each adsorber, calculating the difference between the differential pressure values characteristic of the different adsorbers, the comparison of this difference with a target value and the correction in the event of a difference observed by modification of the transfer of at least one flow of oxygen-rich gas between adsorbers or possibly between adsorber and storage capacity.
