Abstract
Procédé de séparation d'un gaz d'un mélange de gaz, ledit gaz étant le plus condénsable des gaz dudit mélange. Ce procédé se caractérise en ce que l'on envoie ledit mélange de gaz au contact d'au moins une barrière microporeuse présentant une perméabilité de 100 à 1 000 moles d'air/ cm**2/min./cmHg, une épaisseur de quelque microns à quelques dizaines de microns et un rayon de pores de 10 à 100 Angström, on règle la pression partielle dudit gaz le plus condensable et/ou la temperature dudit mélange de gaz en fonction du rayon moyen de pores de ladite barrière, de façon telle qu'il y ait condensation capillaire dudit gaz condensable à l'entrée des pores de ladite barrière et écoulement dudit gaz condensé le long des pores et à travers ladite barrière et on recueille ensuite ledit gaz ainsi condensé. Application à la purification de l'hexafluorure d'uranium provenant d'une usine d'enrichissement isotopique.
