  1. Distillation sous vide :

le choix du vide est d’abaisser la température d’ébullition de ces coupes afin d’éviter le craquage des molécules. Le but de cette distillation est la production des coupes servant de base pour la fabrication des lubrifiants selon leur viscosité . On distingue des distillats léger (SPO), moyen (MVO ou SAE10) et lourd (VO ou SAE30) et un résidu sous vide (RSV)
