Abstract

A process for increasing the proportion of a gas in a gaseous mixture of which it is a component. The gaseous mixture is allowed to be drawn through an adsorbent bed in a substantially unpressurized condition by the action of a reduced pressure applied to an outlet of the bed. The bed is then regenerated prior to a further admission of the gaseous mixture thereto.
