Abstract
Pervaporation is an energy efficient membrane separation technique. Its effectiveness however is affected by many factors including membrane properties, operating conditions and feed condition. Addition of salts is a well-studied technique, especially i n distillation, that enhances separation due to altered molecular interactions. Potassium acetate is a very effective salting-out agent that forms strong interaction with water molecules. Addition of potassium acetate in ethanol-water mixture would theoretically weaken ethanol- water interaction hence easier separation. The effect of 3% and 5% (w/v) potassium acetate on the pervaporation performance of 3% and 5% (v/v) ethanol-water mixture was studied. Pervaporation performance was evaluated using separation factor, enrichment factor, permeate flux pervaporation separation index. It was concluded that the addition of potassium acetate in ethanol-water mixture greatly enhanced the pervaporation performance with 27% and 26% maximum increase in product concentration at high flowrate and low flowrate pervaporation, respectively.
