Abstract
Pervaporation (PV) is an advanced membrane separation technique used for the separation of constant boiling mixtures or Azeotrope. In the purification of ethanol from ethanol/water mixture by distillation, a maximum concentration of 95% by mass can be achieved. At this concentration level, the mixture forms an azeotrope and allows no further enrichment by simple distillation. PV technique has been used for the production of absolute alcohol from industrial alcohol. Experimental work has been done and successful enrichment of industrial alcohol has been achieved operating at normal operating conditions (70 °C and 2.0 bar) using designed PV rig and characterized by Gas Chromatograph (GC).
