聚酯酯交换塔的数学模型——反应精馏塔的模拟计算

Mathematical Model for Ester Interchange Tower ——the Simulation of Distillation with Reaction

本文用三对角矩阵法建立了聚酯（ＰＥＴ）酯交换塔的数学模型，并且通过移动参数的办法对这个数学模型进行了求解，讨论并验证了在用三对角矩阵法模拟反应精馏塔的过程中，选择初值、改善收敛性的几种常用方法。

A mathematical model using tridiagonal matrix for ester interchange tower was developed.A new calculation method,parameter moving,was developed and skills to specify initial value to accelerate comvergence and avoid divergence in the simulation of distillation with reaction were elaborated.
