本文提出了三种新的有效相稳定性判断方法，这三种方法各有相应的应用范围和侧重点。 - 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
该体系具有高度非理想性，气液相平衡模型采用nrtl - hoc和uniquac - hoc模型，采用切平面判据法对进入分层器中的液相进行液相稳定性测试，提供液液相分离计算的初值，再结合牛顿拉夫森迭代法运算求得相分割系数，根据物料衡算求出各相组成，循环迭代可求得分层各组分数据，共沸精馏模拟计算采用那夫塔列-山德荷姆全变量迭代算法。 - Interval newton algorithm is used extensively in the calculation of chemical engineering such as the determination of phase stability , reactive azeotropes , robust process simulation , reliable parameter estimation , etc . all of these results show that interval newton algorithm is suitable to solve most kinds of nonlinear equation successfully
由于区间牛顿法强壮的全局收敛性和同时求得多个解的能力使得区间牛顿法广泛地应用在化工计算领域，如：相稳定性分析、反应共沸物的判断及组成确定、稳态过程模拟、参数估计等等。
