Title (EN) PROCESS FOR REDUCING THE CLOUD POINT OF A BASE OIL
(FR) PROCEDE DE REDUCTION DU POINT DE TROUBLE D'UNE HUILE DE BASE
Abstract: front page image
(EN)The invention relates to a process for reducing the cloud point of a base oil feed having a kinematic viscosity at 100 0C of greater than 10 cSt by separating the molecules inferring the high cloud point from the base oil by (a) depositing said molecules on one side of a cooled surface, (b) obtaining a base oil having a reduced cloud point and (c) melting the deposited molecules and separating the melted molecules from the surface and reusing said surface to perform step (a) .
(FR)L'invention porte sur un procédé de réduction du point de trouble d'une huile de base d'une viscosité cinématique supérieure à 10 cSt à 100 °C, en séparant les molécules agissant sur le point de trouble haut de l'huile de base: (a) en déposant lesdites molécules d'un côté de la surface refroidie; (b) en obtenant une huile de base à point de trouble réduit; et (c) en fondant les molécules déposées et en les séparant de la surface, puis en réutilisant ladite surface pour exécuter l'étape (a).
