“…Organic-inorganic hybrid materials have been proposed to be the best choice for having both the functionality of the organic moiety and the stability of inorganic moiety. Budd et al [25] employed zeolite/polyelectrolyte (chitosan/poly(4styrene sulfonate)) multilayer pervaporation membranes to enhance the yield of ethyl lactate. Adoor et al [26] prepared aluminum-rich zeolite beta incorporated sodium alginate pervaporation membranes.…”

The esterification reaction is reversible and has low yield. In order to increase the yield of reaction, it is required to simultaneously remove the product of reaction. For this membranes are the viable approach. Pervaporation membranes have success in removal of components in dilute forms. Membrane performance is represented in terms of flux, sorption coefficient, separation factor, and permeance. These factors are related to the thickness of membrane, temperature, and feed concentration. Higher flux is observed at lower membrane thickness and higher feed concentration of water and lower selectivity is observed at higher temperatures due to increased free volume, lower viscosity, and higher feed side pressure. Different factors affect the pervaporation aided esterification reactor setup such as effect of initial molar ratios of the reactants, effect of catalyst concentration, effect of membrane area, and effect of temperature. Large membrane size could provide higher surface for the transfer of acid, though the challenges of membrane rupture do surround the studies. In the present review work, we tried to collaborate the works in totality of the pervaporation design starting from the membrane behavior to the process behavior. Different prospective fields are also explored which need investigation.

Membrane separation technology, owing to its low energy consumption, operational simplicity, ease of control and scale-up, has gained increasing interest. The rapid development requires highly selective membranes with high through rates and chemical/mechanical stability. Chitosan, a relatively inert biomaterial with film forming ability, has been rapidly recognised for its potential in separation and purification technology in recent decades. Because of its hydrophilicity, cationicity, biocompatibility, ease of modification, remarkable affinity to dyes, metals and proteins, chitosan membranes have become a promising candidate for several applications. In the present review, the pervaporation of azeotropic mixtures and protein purification and separation of gaseous mixtures using chitosan membranes are discussed. The general overview of the preparation of different chitosan membranes, its capabilities in the separation of various solvents, gases and biomacromolecules are presented. Finally, the opportunities, challenges and perspectives in these areas are discussed.
