Abstract
A repressurization phase of an adsorber comprises a step of first countercurrent repressurization with at least gas from a first co-current decompression of another adsorber, this phase ending in a step of co-current production. Immediately following the first countercurrent repressurization step, air is introduced co-current into the adsorber.
