simulation of benzene extraction with n-hexane as solvent by aspen plus

benzene is used mainly as an intermediate to make other chemicals. in this study, benzene extraction from binary mixture of benzene and acetonitrile with n-hexane as solvent were simulated at t = 298.15k under atmospheric pressure, respectively. the nrtl modelewas used and suitability of hexane as a solvent were evaluated and selectivity and distribution coefficient were calculated. the high value of selectivity factors, is reason for be suitable of the solvent for extraction of benzene.
