A facilitated pervaporation system usually refers to the combination of a pervaporation as a separation unit combined with a chemical reactor for esterification reactions or other equilibrium reactions. The “facilitation” then refers in fact to the reaction, and not the separation. The pervaporation unit removes the side product of the reaction (in case of esterification, this is water) so that the reaction equilibrium shifts to a higher product yield (Van der Bruggen 2010). Other reactions than esterifications can also be facilitated, on condition that they concern an equilibrium reaction and that the side product can be easily removed by a pervaporation membrane (as is the case for water in an organic reaction mixture). For bioconversions, the reaction product(s) are to be removed instead of the by-products, in order to enhance the activity of the microbial population. This is the case, for example, in the production of bioethanol and in ABE (acetone, butanol, ethanol)...
