Abstract

1. Process for the production of superoxygenated air by adsorption, of the type in which air is admitted to one of a pair of molecular sieve adsorption columns (1) and (2), successively and in a cyclic manner in a production stage under rising pressure (B), in a mutual equilibration stage (E - C), with contination of air intake towards the adsorber in the corse of being depressurised, then in the course of regeneration by final depressurisation, characterised by the combination of the following measures : a) until the end of the mutual equilibration stage, the adsorber under depressurisation (E) continues to provide a flow of production gas ; b) throughout the final depressurisation stage (F) after the equilibration, a flow drawn from the production gas flushes the adsorber in the course of depressurisation, in the direction of depressurisation.
