The hybrid distillation-pervaporation process is an efficient method for the removal or recovery of volatile organic compounds from their aqueous mixtures. has not only shown its excellent performance in purification solvent mixtures but also proven to have a potential saving energy. In this study, optimized treatment low-alcohol waste solvents. Three combinations are examined: distillation with hydrophilic pervaporation, organophilic pervaporation and both methods. systems result better term energy-use compared conventional distillation. It observed that combination or/and suitable separation ethanol-water most recommended third layout.Keywords: process, separation, azeo
