Abstract

The method of vacuum distillation of a hydrocarbon feedstock comprises the following steps: heating the feedstock (12); introducing the feedstock into a flash zone of a vacuum distillation column; removal of at least one distillate stream from the vacuum distillation column at an intermediate level; withdrawing a column head stream at the head of the vacuum distillation column; partially condensing the column head stream to recover a liquid flow and a gaseous flow; passing the gaseous flow through a vacuum generator and recovering at least one condensate and a gaseous fraction of non-condensable gas. It is characterized in that the method comprises introducing into the vacuum distillation column a flow of a feedstock-stripping fluid, wherein the stripping fluid comprises a hydrocarbon mixture having a weighted average boiling temperature (Tmav) of between 150° C. and 250° C., preferably between 190° C. and 210° C.
