Title (EN) METHOD OF REFINING CRUDE OIL
(FR) PROCEDE POUR RAFFINER DU PETROLE BRUT
Abstract:
(EN) A method of refining crude oil, which can reduce costs for facility and operation and ensure stable operation under simple control. The method is characterized in that, after distilling and separating naphtha fraction in crude oil, remaining fractions after removal of the naphtha fraction are desulfurized while brought into contact with desulfurizing catalyst and then distilled to be separated into respective fractions. When refining remaining fractions after removal of said naphtha fraction, dexterous introduction of hydrogenating refining treatment, high pressure separation treatment, or residual heavy oil fluid catalytic cracking treatment makes it possible to obtain fractions of kerosine and gas oil of high quality and to increase a yield of intermediate fractions of said oils.
(FR) Est décrit un procédé de raffinage de pétrole brut, qui permet de réduire les coûts d'installation et de fonctionnement et assure un fonctionnement stable moyennant un contrôle simple. Le procédé est caractérisé en ce que, après distillation et séparation de la fraction naphta dans le pétrole brut, les fractions restant après élimination de la fraction naphta sont désulfurées par mise en contact avec un catalyseur de désulfuration puis distillées pour être séparées en fractions respectives. Lors du raffinage des fractions restant après élimination de ladite fraction naphta, le lancement judicieux du traitement de raffinage par hydrogénation, le traitement de séparation haute pression, ou bien le traitement de craquage catalytique fluide des huiles lourdes résiduelles permettent d'obtenir des fractions de kérosène ou de gazole de haute qualité et d'accroître le rendement des fractions intermédiaires desdites huiles.
