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