Separation of azeotropic mixtures using membrane distillation

A multicomponent mass transfer model based on the Stefan–Maxwell formalism is developed to predict membrane distillation performance in separating azeotropic mixtures[1]. The developed model accounts for all coupling interactions between the diffusing species as well as for temperature and concentration polarization effects [2-9]. The model is validated with previously published experimental data of propionic acid/water azeotropic mixture. The model predicts the effect of the process relevant parameters very well.
