Abstract

A process for the separation of a hydrocarbon mixture comprising benzene and xylene isomers including ortho-xylene, which comprises charging said mixture into a benzene distillation column, supplying heat to the lower part of said benzene column by indirect heat exchange in a re-boiling zone with condensed water vapor obtained from a water vapor generation zone, recovering from said benzene column a benzene-rich head fraction and a fraction of tails substantially free of benzene, passing at least one portion of said fraction of tails from the benzene column to a xylene distillation column working under a pressure in the upper part in the range of 0.68 to 6.8 absolute atmospheres, passing the vapors of heads of said column of xylene through said zone of generation of water vapor and condensing in said said head vapors by indirect heat exchange with water at boiling under controlled pressure and at a temperature higher than the temperature of said bottoms of the benzene column, recovering from said water vapor generating zone a condensed heads fraction comprising metaxylene or paraxylene.
