- ". Fermenting molasses using Clostridium Acetobutilycum can produce a mixture of acetone (1)/ethanol (2)/water (3)/ n-butane (4). The fermentation products are then separated and purified in a series of distillation column. This work is primarily concerned with the effect of operating pressure increased from 0.6 atm to atmospheric on the distillation column performance. Distillation column was designed using computer programs written in VISUAL FORTRAN 5.0. A rigorous equilibrium based calculation method due to Wang-Henke that taking into account the effects of non-equal molar overflow and non-ideal vapor-liquid equilibrium was used in study. UNIQUAC, a method of estimating activity coefficient in non-ideal liquid mixtures, was used to model the vapor�liquid equilibrium. The column performance was studied by varying the operating pressure that is constrained by the cooling water temperature in the condenser. The numbers of plates are 50 and feed plate location at 12th plate below the condenser for acetone column. By increasing pressure 0.6 atm to atmospheric for acetone column increased 19.58% reflux ratios, 13.22% condenser and 15% reboiler duty. On atmospheric condition distillation column need supplied energy 653,312 cal/hr. The product was 99.4-wt % acetone and 98% recovery of acetone. Key word : Computer simulation, distilation column, purity of ethanol.
