Abstract

An improvement to a continuous solvent extraction-steam distillation process for the recovery of aromatic hydrocarbons in the range of C.sub.6 -C.sub.16 from a feed stream containing such aromatics and aliphatic hydrocarbons in the range of C.sub.5 -C.sub.16 which resides in utilizing two heat exchangers wherein the heat of condensation of the overhead stripper vapor and vapor sidedraw products is recovered and utilized to vaporize the stripping water, thereby producing stripping steam which in turn is compressed up to the pressure present at the bottom of the stripper and resulting in the reduction of the heat load of the process.
