Abstract
A system for obtaining oxygen-enriched air from ambient air comprises an absorber moving bed separating unit whose adsorption material binds oxygen and nitrogen to a different degree. To flush out moisture remaining in the moving bed material, it is proposed to connect a useful gas store which comprises the oxygen-enriched air to the inlet of the separating unit at time intervals via a controllable flush valve, and to flush the moisture out of the moving bed material in the useful gas store by means of dry gas. This shortens the start phase which elapses after switching on until steady-state conditions are established.
