Abstract
A process for refining or pre-refining a crude oil P is described in which P is fractionated into several fractions, wherein partial oxidation of an asphaltenic residue R1 derived from P is carried out to produce a synthesis gas SG1 with an H/CO ratio of less than 1, steam cracking is carried out of an external light hydrocarbon fraction to produce a synthesis gas SG2 with a H/CO ratio of more than 3; SG1 and SG2 are mixed to produce a synthesis gas SG with a H/CO ratio in the range 1.2 to 2.5, and SG is converted by Fischer-Tropsch synthesis, then the waxes produced are converted into middle distillates. Preferably, a vacuum distillate VGO and/or a deasphalted oil DAO derived from P are hydrocracked mixed with the waxes. The invention also pertains to a facility for carrying out the process.
