Abstract

L'invention se rapporte au génie chimique. Elle concerne un procédé de récupération de chlorures métalliques à partir d'un mélange gazeux essentiellement formé d'au moins deux chlorures métalliques gazeux, caractérisé en ce que l'on met le mélange gazeux en contact, à une température supérieure au point de condensation de ce mélange, avec au moins un courant de liquide 6 de manière à refroidir rapidement substantiellement tout le mélange gazeux à une température inférieure au point de solidification d'au moins un des chlorures métalliques du mélange gazeux, la vitesse du mélange gazeux étant au moins égale à la vitesse de transport pneumatique dans la zone de contact et le temps necessaire pour refroidir substantiellement tout le mélange gazeux étant inférieur à une seconde. Utilisation dans la production de tétrachlorure de titane.
