Abstract

Le procédé pour supprimer l'eau et/ou d'autres impuretés volatiles de l'huile de graissage, notamment d'un moteur à combustion, consiste à soumettre l'huile, de préférence après passage à travers un filtre (11), à un chauffage dans une chambre de vaporisation (4), dans laquelle est maintenue une dépression comprise de préférence entre 20 et 30 bar. De cette manière, l'eau et les autres impuretés volatiles liquides sont vaporisées. Les vapeurs dégagées sont conduites hors de la chambre de vaporisation (4). L'installation pour la mise en oeuvre du procédé comporte une chambre de vaporisation (4) présentant au moins une entrée (10) pour l'huile à nettoyer, une sortie (21) pour l'huile purifiée et une sortie (22) pour les vapeurs, cette sortie (22) étant reliée par une conduite (6) à un dispositif de mise sous vide (7, 8).
