Abstract: A process for hydrocracking a petroleum feedstock involves: (a) hydrocracking the feedstock to obtain a hydrocracked effluent; (b) liquid/gas separation of the effluent to obtain a gaseous effluent and a liquid effluent; (c) fractionating the liquid effluent at a pressure P1, producing a first distillate and a first residue, (d) recycling a first portion of the first residue to hydrocracking, (e) rectifying a second portion of the first residue at a pressure P2 lower than or equal to the pressure P1, to obtain a secondary distillate, a secondary residue and a vapor stream, (f) purging a portion of the secondary residue, and (g) recycling all or part of the secondary distillate to hydrocracking.
