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
該體系具有高度非理想性，氣液相平衡模型採用nrtl - hoc和uniquac - hoc模型，採用切平面判據法對進入分層器中的液相進行液相穩定性測試，提供液液相分離計算的初值，再結合牛頓拉夫森迭代法運算求得相分割系數，根據物料衡算求出各相組成，循環迭代可求得分層各組分數據，共沸精餾模擬計算採用那夫塔列-山德荷姆全變量迭代演算法。 -
The optimum results are gotten by simulation of changing the value of some variable such as feed position, theoretical tray. the optimum value can be used to guide industrial design. both isopropyl acetate and butyl acetate as azeotropic agent are contrast to each other according to operational data. besides, liquid - liquid equilibrium still is designed by onself, and its credibility is checked by the experimental data of the system acetic acid water - isopropyl acetate at 24
對乙酸-水-乙酸異丙酯體系和乙酸-水-乙酸丁酯體系，分別進行了進料板位置、理論板數的優化計算，得到的優化結果可用於指導工業過程的設計；對採用乙酸正丁酯和乙酸異丙酯作夾帶劑時的操作進行了綜合比較。
