Abstract (en)
[origin: CN107541290A] The invention relates to a method for a deep hydroconversion process using an extraction of aromatics and resins, with upgrading of the hydroconversion extract and raffinate in downstream units. The method includes the following steps: a) ebullated bed hydroconversion of a feed in the presence of hydrogen during hydroconversion; b) atmospheric fractionation of at least a hydroconverted effluent obtained from the step a) to produce a fraction containing a gasoline fraction and a gas fraction and atmospheric residues; c) vacuum fractionation of at least a portion of the atmospheric residues obtained from the step b) to obtain a vacuum gas oil fraction and an unconverted vacuum residue fraction; d) deasphalting of at least a portion of the unconverted vacuum residue fraction obtained from thestep c); and e) liquid/liquid extraction on a hydrocarbon fraction of depleted asphaltenes to produce an extract enriched in aromatics and resins and an extract depleted in aromatics and resins, at least a portion of the extract sent to an inlet of the hydroconversion as an aromatic diluent.
