Abstract

Cette invention concerne un procédé permettant d'éliminer les impuretés dans des substances simples ou complexes, ainsi que dans des composés organiques ou non organiques. Ce procédé, qui comprend deux étapes, consiste à faire passer ces éléments en phase vapeur dans un tube sous vide. Lors de la première étape, la substance contenant des impuretés est placée dans un conteneur équipé d'une buse, puis chauffée de manière à créer un flux laminaire dans la zone de travail du tube. Lors de la seconde étape, on exerce sur ce flux une ou plusieurs actions géométriques en disposant dans ledit tube des inserts qui possèdent des canaux traversant ainsi qu'une surface développée. La section de passage de l'insert est supérieure à la section de la buse de sortie du conteneur, mais inférieure à la section de passage de l'insert suivant dans le sens d'écoulement du flux. La zone de travail est maintenue à une température qui est supérieure à celle correspondant au point de condensation critique de la substance à purifier. Lorsque l'on exerce l'action géométrique sur le flux, ce dernier se divise en au moins deux flux isolés. La substance purifiée est ensuite récupérée dans un élément de refroidissement dans lequel les vapeurs de ladite substance purifiée se trouvent à une pression allant de 10?-3 à 10-5¿ Torr. Lors de la purification, des turbulences locales assurent la création d'une couche de diffusion et de bordure à la sortie du conteneur d'alimentation ainsi qu'au niveau des inserts, ce qui permet d'obtenir un taux de purification élevé des substances.
