processo para a redução do ponto de névoa de uma alimentação de óleo de base

摘要

The invention relates to a process for reducing the cloud point of a base oil feed having a kinematic viscosity at 100° C. 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).
