A study was conducted to evaluate membrane pervaporation for the separation of diacetone alcohol-water mixtures using commercially available membranes for organic enrichment and dehydration. Empirical correlations for the effect of the process parameters of feed concentration, feed temperature, permeate-side pressure, and scale-up were developed. The solvent-water mixture was successfully separated with a poly(vinyl alcohol) based Sulzer PERVAP 2210 dehydration membrane. Various dehydration membranes were evaluated and a comparison of the flux and separation factor was made. The membrane performance in separating acetone-water mixtures was also studied. An overall model to predict the membrane area needed for a scale-up was developed based on the results.
