进料组成改变对隔板塔经济性影响的模拟

摘要

完全热耦合精馏相比传统精馏可以减少设备投资和操作费用，可代替传统精馏分离多组分混合物。对隔板塔（完全热耦合精馏塔）用于分离三组分混合物时的可操作性和经济性进行了研究。采用严格模拟方法，针对4种不同的进料组成设计了4种不同的隔板塔，并得出各个隔板塔气相和液相分割比对隔板塔年度总费用（TAC）的关系曲线，研究了当进料组成改变时4种隔板塔的经济性。

Abstract：

Fully thermally coupled distillation columns(FTC) or divided wall column(DWC) can reduce energy consumption and capital investment compared with conventional distillation consequences and therefore becomes an attractive alternate to traditional distillation column for the separation of multicomponent mixtures. Economical behavior and flexibility of DWC were numerically investigated when it was used to separate a three-component mixture. Four DWCs based on four different compositions were designed by rigorous simulation and then simulated to show the dependence of a total annual cost (TAC) of the columns on the vapor and liquid split ratio. Economical behavior of four divided wall columns in case of changes in feed composition was demonstrated as well.
