Hydrocracking process

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 distilla...

Summary: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.
