用物料衡算校正温度的逐板计算

Correcting Temperatures by the Material Balance for Multicomponent Multistage Separations

本文改进了以往通过将组成圆整，用泡点法求温度的方法，采用物料衡算方程与总和方程相结合求温度的思想，同时将用逐板计算得到的液相组成进行校正。通过对十几组极性与非极性物系的考核表明：该方法具有较好的收敛特征，且对初值的要求不高，能够用于复杂精馏塔的模拟计算。

The authors combined the material balance equations and the summation equations to solve the equilibrium temperature,and then corrected the compositions of liquid phase calculated by Gauss-Seidel method by the material balance equations.The proposed method could be applied to multicomponent,multistage separations and always provides convergent solutions under different initial values.
