Abstract
The separation of a gaseous mixture of at least three components, by permeation, wherein a more permeable component, e.g. hydrogen, is separated from an intermediately permeable component and a less permeable component, e.g. CO.sub.2 and CO, respectively, in a first permeator. The residue from the first permeator, e.g. CO.sub.2 and CO, is introduced into a second permeator in which the intermediately permeable component, e.g. CO.sub.2, is separated from the less permeable component, e.g. CO. The less permeable component, e.g. CO, is then directly and completely introduced into the downstream side of the first permeator, where it rejoins the more permeable component, e.g. H.sub.2. The partial pressure of the more permeable component in the starting gaseous mixture, e.g. H.sub.2, is maintained higher than its partial pressure in the final mixture of e.g. H.sub.2 and CO.
