The pervaporation of hydrogen peroxide from an aqueous solution using a perfluorinated membrane reinforced with poly(tetrafluoroethylene) fiber (Nafion® 424) was investigated. Applying sorptiondiffusion mechanism and an Arrhenius relationship for the temperature dependency, a semiempirical model was developed to predict the pervaporation performance in terms of permeate flux and selectivity. Hereby, effects of the operating conditions, including feed concentration, feed temperature, feed flow rate, and permeate pressure, were theoretically calculated and compared with the experimental data. In addition, the required membrane area and operation time for the up-scale of such a pervaporation process were also calculated from the developed model. |
