Abstract:
Summary The recovery and concentration of diacetyl from aqueous solutions by pervaporation was studied with a PDMS-PC membrane at 33°C. Flux decreased with partial pressure and increased with temperature and concentration of diacetyl. Selectivity values greater than 30 were obtained. Whey permeate components had no effect on pervaporation parameters.
