Abstract:
A process for converting a hydrocarbon feed in which said feed is treated in a distillation zone producing an overhead distillate and a bottom effluent, associated with a reaction zone which is at least partially external, comprising at least one catalytic bed in which at least one conversion reaction of at least a portion of at least one hydrocarbon is carried out in the presence of a catalyst and a gas stream comprising hydrogen, the feed for the reaction zone being drawn off from the distillation zone at the height of at least one draw-off level and representing at least a portion of the liquid flowing in the distillation zone, at least a portion of effluent from the reaction zone being re-introduced into the distillation zone at the height of at least one re-introduction level, so as to ensure continuity of distillation, said process being characterized in that at least one liquid effluent is withdrawn from the distillation zone at the height of at least one withdrawal level, at least a portion of said liquid effluent being at least partially treated in a gas-liquid side separation zone (splitter) wherein at least part of the splitter gaseous effluent is re-introduced into the distillation zone and wherein at least part of the splitter liquid effluent is recovered as an intermediate cut, and a stabilised liquid effluent is also withdrawn as a second sidestream from a draw-off level located below the upper distillate level, said stabilised liquid effluent being either at least partially recovered as a product or at least partially mixed with the bottom effluent.
