Abstract:
    A permeation separation method wherein a gas mixture is separated in two membrane systems (3A, 5A) of which only the first (3A) is resistant to an impurity contained in the mixture. Said first membrane system is swept with a fluid having a very low partial pressure for the impurity, thus causing permeation of the impurity. The non-permeate gas from the first system is then fed into the second system (5A).
