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 using two extractive distillation zones thermally linked to recover heat and solvent, thereby resulting in a heat savings.
