文摘:本文通过物料衡算建立产酸相的酸化特性分段模型，并通过模型从理论上分析了膜分离对两相生物系统酸化特性的影响。 - 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。
