Title
(EN) METHOD AND APPARATUS FOR THE PERMEATION SEPARATION OF A GAS MIXTURE
(FR) PROCEDE ET INSTALLATION DE SEPARATION D'UN MELANGE GAZEUX PAR PERMEATION
Abstract
(EN)
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).
(FR)
Dans un procédé de séparation par perméation, un mélange gazeux est séparé dans deux systèmes membranaires (3A, 5A) dont seul le premier (3A) est résistant à une impureté contenue dans le mélange. Ce premier système membranaire est balayé par un fluide ayant une pression partielle très faible pour l'impureté, ce qui induit la perméation de l'impureté. Le gaz non-perméat du premier système est ensuite envoyé au deuxième système (5A).
