| Abstract: | Pervaporation of
benzene-cyclohexane mixtures has been carried out in an agitated batch
permeation cell (with vacuum maintained downstream) using a proprietary
composite membrane of polyvinyl alcohol (PVA) on a porous polyacrylonitrile
(PAN) support, at 298 K and 0.8 torr downstream pressure. Effect of operating
parameters like feed solute concentration, CL0
and agitator speed, n on the overall
solute permeate flux has been elaborately studied. Based on the experimental
data, an attempt has been made to predict mass transfer coefficient and
pervaporative mass transfer flux, from semi-empirical approach. The predictive
equations for the two above mentioned design parameters are presented. |
