Abstract (en)
[origin: WO2018224738A1] The invention relates to a process for distilling petroleum products, comprising a step of distilling said products in a crude oil atmospheric distillation (CDU) or vacuum distillation (VDU) column (1,1'), said column (1,1') itself comprising a plurality of draw-off trays, including an upper draw-off tray (6, 6') which is the draw-off tray closest to the top (3, 3') of said column (1,1'), the process further comprising a step of drawing off the distillate (7,7') present at said upper draw-off tray (6, 6'), and being characterized in that it also comprises a step of separating said distillate (7,7') thus drawn off into, on the one hand, a primary fraction (9) that includes precipitated chlorinated salts and, on the other hand, a remaining fraction (10). Distillation of petroleum products.
