AbstractWhen butanol and water are mixed at a proper ratio, phase separation can occur because of the immiscibility of butanol with water. A highly concentrated aqueous butanol solution in the organic phase can be obtained. Thus, in this study, the phase separation of the permeate was examined during pervaporation (PV) of an acetone-butanol-ethanol-water solution (ABE-water solution) to obtain a high permeate organic concentration. The effects of feed composition and operating temperatures on the phase separation of the permeate obtained during pervaporation of acetone-butanol-water and ethanol-butanol-water solutions were first evaluated with different membranes. Acetone and ethanol both hindered the phase separation of the permeate because of their miscibility with water and butanol. In the separation of the acetone-butanol-water solution, higher temperatures and lower acetone concentrations in the feed solution favored phase separation in the permeate, whereas for the ethanol-butanol-water solution, lower temperatures and lower ethanol concentrations in the feed solution led to relatively facile phase separation in the permeate. Pervaporation of a 1.5 wt% ABE-water solution with different membranes at different temperatures was also performed. When phase separation in the permeate occurred under proper conditions, the ABE concentration in the organic phase reached approximately 68 wt%. (C) 2014 Elsevier B.V.
