一、引言传热系统的最优设计成为当前化工过程最优化的重要研究课题之一,引起了国外很多研究者的兴趣。从Hwa1965年发表的利用可分规划(Separable programming)寻找传热系统的最优组合的论文算起,到目前为止已经发表了十多种组合方法。但是从公开发表的文献来看,还多处于探索性阶段,离实际应用还有一段距离。因为传热系统的最优 I. INTRODUCTION The optimal design of heat transfer system has become one of the most important research topics in the current chemical process optimization and has aroused the interest of many foreign researchers. So far, more than a dozen combinations have been published so far, from the paper published by Hwa in 1965 on Separable Programming to find the optimal combination of heat transfer systems. However, from the published literature, it is still in an exploratory stage and still has some distance from practical application. Because of the optimal heat transfer system
