Abstract

An improvement to a continuous solvent extraction-­ steam distillation process for the recovery of aromatic hydro­ carbons in the range of C₆-C₁₆ from a feed stream containing such aromatics and aliphatic hydrocarbons in the range of C₅-­ C₁₆ which resides in utilizing one heat exchanger wherein the vapor sidedraw products are compressed and the heat of con­ densation of the vapor sidedraw products are utilized to vapor­ ize stripping water thus producing stripping steam thereby reducing the heat load of the process.
