Abstract

a) Procédé pour séparer des composants sublimables de mélanges gazeux par dépôt sur des surfaces d'un appareil échangeur de chaleur. b) Procédé caractérisé en ce que l'on produit sur ces surfaces un profil d'épaisseur de couche voulu sublimé, dans le sens opposé à la direction du courant de mélange gazeux dans l'échangeur de chaleur, dans des conditions telles que la répartition de la température de l'échangeur de chaleur n'étant pas fixe, la position du point de rosée au commencement de la séparation est déplacee, d'un point donné au préalable à l'extremité froide de l'échangeur, avec une vitesse réglée, vers l'extrémité chaude de cette échangeur. c) Procédé applicable à la séparation d'hexafluorure d'uranium.
