Abstract

La présente addition est un perfectionnement au procédé de purification d'un gaz résiduaire contenant des polluants gazeux. On introduit un courant ascendant de gaz résiduaires au fond d'une colonne présentant une multiplicité de plateaux étagés et en même temps qu'on introduit en tête de la colonne du charbon activé, et l'on met en contact le gaz résiduaire avec le charbon activé pour former un lit fluidisé sur chacun des plateaux étagés, de telle sorte que les polluants gazeux sont adsorbés sur le charbon activé. On peut purifier en continu le gaz résiduaire par recyclage du charbon activé sous forme de sphères et adopter pour les cuvettes étagées des plaques perforées de dessin approprié. Le gaz résiduaire ainsi purifié peut être dégagé dans l'atmosphère, débarassé des éléments nocifs qu'il contenait.
