This invention is directed to a process for hydroprocessing vacuum gas oils and other feeds in order to produce unconverted oil suitable for use as base oil feed for white oils, Group III oils, and BMCI (Bureau of Mines Correlation Index) ethylene plant feed. Ammonia, hydrogen sulfide, and light products are removed from the first stage at high pressure in order to produce a higher quality of unconverted oil that is suitable for Group III base oils.
La présente invention concerne un procédé d'hydrotraitement de gazoles sous vide et d'autres charges d'alimentation afin de produire une huile non transformée adaptée à une utilisation en tant que charge d'alimentation en huile de base pour des huiles blanches, des huiles du groupe III, et des charges d'alimentation végétale à base d'éthylène BMCI (à indice de corrélation). L'ammoniac, le sulfure d'hydrogène et des produits légers sont retirés de la première étape à haute pression afin de produire une qualité plus élevée d'huile non transformée convenant aux huiles de base du groupe III.
