摘要
This article presents a simulated annealing-based approach to the optimal synthesis of distillation column considering intermediate heat exchangers arrangements. T-he number of intermediate condensers and/or intermediate reboilers, the placement locations, the.operating pressure of column, and the heat duties of intermediate heat exchangers are treated as optimization variables. A novel coding procedure making use of an integer number series is proposed to represent and manipulate the structure of system and a stage-to-stage method is used for column design and cost calculation. With the representation procedure, the synthesis problem is formulated as a mixed integer nonlinear programming （MINLP） problem, which can then be solved with an improved simulated annealing algorithm. Two examples are illustrated to show the effectiveness of the suggested approach.
这篇文章就中间的热 exchangers 安排而言介绍一条模仿的退火底途径给蒸馏柱的最佳的合成。中间的 condensers 或中间的使再沸 ers，放置地点，列的操作压力，和中间的热 exchangers 的热责任的数字被当作优化变量。使用一个整数数字系列的一个新奇编码过程被建议代表并且操作系统的结构，一个 stage-to-stage 方法被用于列设计和费用计算。与表示过程，合成问题作为一个混合整数被提出非线性的编程(MINLP ) 问题，它然后能与一个改进模仿的退火的算法被解决。二个例子被说明显示出建议途径的有效性。
