The azeotropic distillation of the system acetic acid - water - azeotropic agent ( isopropyl acetate and butyl acetate ) is simulated. due to the non - ideal behavior, nrtl - hoc and uniquac - hoc model is used to depict vapor - liquid phase equilibrium behavior of this system. concerning the liquid in the decanter, the stability is checked by tangent plane stability analysis, and the initialization of phase splitting calculation is produced. a good estimate of the phase fration is gotten by successive substitution with newton ' s method, and every component of two phase is gotten by mass equilibrium equation. finally, the solution of this equation is produced with successive substitution calcultion. the naphtali - sandholm method is used to simulation of azeotropic distillation. by virtue of this combined calculation method, the simulation is begun with operational data as basical data. the results of simulation accord with the operating data, which proved that the combined calculation method is credible
