Abstract

Procédé pour extraire la cire contenue dans les huiles de pétrole par un procédé de dilution progressive amélioré. Le mélange huile-solvant refroidi contenant de la cire solide entraînée et dispersée en son sein est éliminée de l'échangeur de chaleur 12 par le conduit 17 et mélangé à un solvant complémentaire en provenance du conduit 13 et du conduit 18. Le mélange résultant huile-solvant est encore refroidi dans l'échangeur de chaleur à parois de raclage 20 à la température de filtration souhaitée par un réfrigérant convenable pénétrant dans l'échangeur de chaleur par le conduit 21 et évacué de cet échangeur par le conduit 22. Application aux huiles lubrifiantes.
