This project focusing on separating Isopropyl-Alcohol (IPA) – Acetone mixtures into desired purity in distillation process unit. The experiment is conducted in Pilot Scale Distillation Unit in UTP Academic Block and simulation is prepared using Aspen HYSYS. This project presents a development of inferential model to provide standard product estimator for distillate in distillation column. This model acts like a ‘soft sensor’ that is able to give product properties online like hardware sensors. It is developed by Microsoft Excel Solver using existing variables data from experiment. Based on the analysis, performance of inferential model are good in predicting product composition with less error and high accuracy when compared with HYSYS simulation.Case studies were perform in changes of variables of reflux rate and steam rate.
