THE PERFORMANCE OF PERVAPORATIVE AROMA RECOVERY UNITS - PROCESS SIMULATIONS

Pervaporation is an emerging membrane-based separation technique which is very promising, for instance, for aroma recovery. Computer simulat ions of the behavior of large-scale pervaporation units for aroma reco very indicated that aroma concentrates can be produced by using this t echnique. For four of the five aroma compounds investigated, the degre es of recovery were high. The simulations showed that some process par ameters, e.g., temperature, degree of aroma folding, and membrane mate rial, strongly affect the performance of the process.
