    Abstract

    A simulation on separating binary system has been studied to investigate the temperature andliquid compositions profiles in the bottom changing with time. By having temperature and liquid compositiQns profiles in the bottom,one can find whether the binary mixture forms azeotropes or zeotropes mixtures. Antoine equation has used to calculate saturated vapour pressure at atmospheric pressure. The activity coefficient was calculated using UNlQUAe. FQrward jinite-difforence was used to get thecalculaled value of the bottom still composition at a given time starting from a given initial composition of binary system. several initial values of the composition binary syste.m. had been chosen to complete. liquid compositions in the. bottom. The. results showed that the temperature profiles of acetone-n-hutanol and ethanol-n-hutanol binary system have d'zjferences characterfsJic from acetone-ethanol binary system. Those can be seenfrom activity coeffiCient profile. The results showed that the binary system formed zeotropes mixture, without having any azeotropes mixtures o/its components. The results simulation on separation binary system has been comparation with hydrocarbon binary system benzene-toluene mixture.
