The invention relates to a process for treating heavy petroleum feedstocks for producing a gas oil fraction that has a sulfur content of less than 50 ppm and most often 10 ppm that includes the following stages: a) ebulliated-bed catalytic hydrocracking, b) separation from hydrogen sulfide of a distillate fraction that includes a gas oil fraction and a heavier fraction than the gas oil, c) hydrotreatment of said distillate fraction, and d) separation of a gas oil fraction with less than 50 ppm of sulfur. Make-up hydrogen, preferably all make-up hydrogen, is to stage c). Advantageously, the heavier fraction from step (b) is subjected to catalytic cracking. The invention also relates to an installation that can be used for implementing this process. Figure 1 to be published.
L' invention concerne un procédé de traitement des charges pétrolières lourdes pour produire une coupe gazole ayant une teneur en soufre inférieure à 50 ppm et le plus souvent 10 ppm qui comprend les étapes suivantes : a) hydrocraquage en lit bouillonnant de catalyseur, b) séparation du sulfure d'hydrogène, d'une coupe distillat incluant une fraction gazole et d'une fraction plus lourde que le gazole, c) hydrotraitement de ladite coupe distillat, d) séparation d'une coupe gazole à moins de 50 ppm soufre. Le procédé opérant avec de l'hydrogène d'appoint amené au niveau de l'étape c) et très avantageusement tout l'hydrogène d'appoint du procédé est introduit à. l'étape c). Avantageusement la fraction lourde est envoyée en craquage catalytique. L'invention concerne également une installation utilisable pour mettre en oeuvre ce procédé. Figure 1 à publier.
