title = "Membrane pervaporation process for diacetone alcohol - Water separations",
abstract = "Membrane pervaporation is a very effective technology for organic solvent-water separations in specialty chemical manufacture. It has the ability to perform solvent dehydrations and produce solvents of high purity without complex distillations. Pervaporation has been successfully utilized in the dehydration of diacetone alcohol (DAA)-water mixtures. The use of a polyvinylalcohol membrane was quite selective for the parameters studied. At benchmark processing conditions of feed concentration of 90% DAA, 50°C and 2 mm Hg (abs) permeate-side pressure, water selectivity was 169.9 and total flux was 0.26 kg/sq m2-hr. Feed temperature affected flux in an exponential manner. Data correlated well, and empirical models were developed. The model predicts that a membrane area of 85 sq m is needed to achieve a final product purity of 99% DAA from a feed of 90% DAA. This is an abstract of a paper presented at the AIChE Annual Meeting and Fall Showcase (Cincinnati, OH 10/30/2005-11/4/2005).",
