The invention relates to a method for prerefining crude oil P during which P is fractionated into a number of fractions, typically, certain fractions are hydrotreated, hydrocracked or hydroconverted. These fractions are then recomposed and, in general, at least two pre-refined oils Pa and Pc are produced, Pa being a high-quality non-asphaltenic oil, and Pc being a residual oil. The method typically involves at least one initial distillation and a deasphalting SDA with a solvent having a molecular weight of at least 50 for separating a deasphalted oil DAO from a flow of virgin asphalt AS. AS is hydroconverted in at least two series-connected ebullated-bed reactors with a moderated conversion of less than 56 %, mixed with a virgin diluent containing light fractions. The DAO is typically hydrocracked with a conversion limited to less than 80 %.
Procédé de pré-raffinage d'un pétrole brut P dans lequel on fractionne P en plusieurs fractions, typiquement on hydrotraite, hydrocraque, ou hydroconvertit certaines d'entre elles, puis l'on recompose ces fractions et l'on produit généralement au moins 2 pétroles pré- raffinés Pa, Pc, Pa étant un pétrole non asphalténique de haute qualité, et Pc étant un pétrole résiduaire. Le procédé comprend typiquement au moins une distillation initiale et un désasphaltage SDA avec un solvant de poids moléculaire au moins 50 pour séparer une huile désasphaltée DAO d'un courant d'asphalte vierge AS. AS est hydroconverti dans au moins 2 réacteurs en lit bouillonnant en série, à conversion modérée inférieure à 56%, en mélange avec un diluant vierge comprenant des fractions légères. La DAO est typiquement hydrocraquée à conversion limitée inférieure à 80%.
