Pervaporation Process for Ethanol-Water Mixture
Journal Title: International Journal of Research in Chemistry and Environment (IJRCE) - Year 2011, Vol 1, Issue 2
Abstract
Binary or ternary mixtures can be separated by partial vaporization through a dense perm selective membrane. Separation technique has been termed pervaporation in order to accentuate the fact that the permeate undergoes a phase change, from liquid to vapor, during the membrane separation process. Pervaporation process, the feed mixture is maintained in direct contact with one side of the membrane, and the permeate is evolve in the vapor state from another side of the membrane at low pressure. The permeate is together, in the liquid state after condensation, on a cooled wall process known as Pervaporation. A batch stirred cell was used to study the PV behavior of water–ethanol mixtures through the membrane. The permeate flux, selectivity, PV separation index (PSI), flux and selectivity were studied as a function of increasing ethanol concentration in the feed. The membrane was originated highly selective to water. Even when the feed was rich in ethanol the permeate contained higher than of water. In Pervaporation experiments, made at different ethanol feed concentration and temperature present in the feed, permeate through the viable Pervaporation membrane.
