Abstract
An improved process for separating a gaseous mixture comprising the steps of feeding the mixture through an adsorbent bed to remove one or more components from the mixture, cooling and rectifying the enriched mixture obtained from the adsorbent bed, and regenerating the adsorbent bed purging it with a waste gas stream obtained from the rectification of said enriched mixture.
