초록

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.

청구항

In a process for increasing the proportion of a selected component in a gaseous mixture wherein the process employs an absorbent bed which preferentially adsorbs one or more other components of the mixture, the bed having an inlet for the gaseous mixture at one end and an outlet for product gas at its opposite end, the improvement comprising repeating a cycle of operation which includes the successive steps of: allowing the gaseous mixture in a substantially unpressurized condition to be drawn into the bed through said inlet while simultaneously withdraw...
