WINE AROMA CONCENTRATION BY USING A GENERAL-PURPOSE SIMULATOR (PROSIM)

In this work is proposed the application of the ProSim process simulat or for the analysis of wine aroma concentration by performing a two-le vel simulation: First, ProSim is used to attain a preliminary design o f a distillation tower, and afterward the simulator is employed to ana lyze the behavior of the tower in a more precise way. The UNIFAC model was used for nonideal behavior description of the mixtures. In this a pplication, the concentration of a 13-compound mixture was simulated. In fact, the numerical methods implemented in ProSim made it possible to attain the convergence quickly even with minor compounds. The resul ts obtained showed that the use of ProSim results to be very advantage ous because it is timesaving and improvements are attained with respec t to the specific programs developed by researchers.
