2. 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
