A process for treating a hydrocarbon feed having a sulfur content of at least 0.5% by weight, an asphaltenes content of at least 1% by weight, an initial boiling temperature of at least 340 ° C and a final boiling point of at least 480 ° C, making it possible to obtain at least one deasphalted oil fraction having a sulfur content less than or equal to 0.5% by weight and a sediment content less than or equal to 0.1% by weight, comprising the following successive stages: a) a hydrotreatment stage, b) optionally a stage of separation of the effluent obtained at the end of stage a), c) a stage hydroconversion of at least part of the effluent from step a) or at least part of the heavy fraction from step b) and optionally at least part of the light fraction from step b), d) a step of separating the effluent from step c), e) at least one step of selective deasphalting of at least part of e the liquid hydrocarbon fraction resulting from step d), f) a step of recycling at least a part of said deasphalted oil fraction resulting from step e) upstream from hydrotreatment step a) and / or at the start of hydroconversion step c). |
