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. CO2 and CO, respectively, in a first permeator. The residue from the first permeator, e.g. CO2 and CO, is introduced into a second permeator in which the intermediately permeable component, e.g. CO2, 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. H2. The partial pressure of the more permeable component in the starting gaseous mixture, e.g. H2, is maintained higher than its partial pressure in the final mixture of e.g. H2 and CO.

Process for separating a component of intermediate permeability from a gaseous mixture including also at least a more permeable component and a less permeable component, comprising introducing a said mixture into an upstream side of a first permeator having an upstream side and a downstream side, introducing residue from said upstream side into an upstream side of a second permeator having an upstream side and a downstream side, removing said component of intermediate permeability from the downstream side of said second permeator, introducing a residue from the upstream side of said second permeator substantially directly and totally into the downstream side of said first permeator, withdrawing from the downstream side of said second permeator a mixture of said more and less permeable components, and maintaining the partial pressure of said more permeable component in said mixture in said upstream side of said first permeator higher than the partial pressure of said more permeable component in said downstream side of said first permeator.
