The pervaporation of hydrogen peroxide from an aqueous solution using a hybrid Nafion®-silica membrane (containing 10 wt% of SiO2) was investigated. An approachto themodeling of the pervaportion process was presented. The approach was based on a semiempirical model which was developed by applying sorptiondiffusion mechanism and an Arrhenius relationship for the temperature dependency to predict the pervaporation performance in terms of permeate flux and selectivity. Hereby, effects of the operating conditions including feed concentration, feed temperature and permeate pressure, were calculated and compared with the experimental data. In addition,the required operating time for the scale-up of such a batch pervaporation process with a given retentate hydrogen peroxide was estimated from the developed model. |
