摘要

质量交换网络（MEN）和热交换网络（HEN）之间有较强的交互作用，传统的夹点技术很难考虑两个网络之间的相互作用。针对这一问题，采用基于分级超结构的数学规划法分步综合热集成的MEN。该方法首先分析了连接两个网络的关键参数，将其离散化处理后组合成多个备选方案，然后对每个备选方案采用分步策略。第一步，用超结构法以总年度费用（TAC）最小为目标综合MEN;第二步，从第一步的结果中抽提出HEN综合所需数据，通过求解基于HEN超结构的非线性规划（NLP）模型，得到优化的HEN总年度费用。加和两步中的TAC结果得到该方案下两个网络的总费用，通过比较所有备选方案下的总网络TAC，以总网络TAC最小的方案为最佳方案。与文献中例子比较，表明本方法具有更好的可行性和有效性。

Abstract

This paper deals with the synthesis of heat integrated mass exchanger networks by mathematical programming approach based on stage-wise superstructure representation.A design strategy was proposed after analyzing all the parameters connecting mass exchanger networks (MEN)with heat exchanger networks (HEN）.Those parameters were discretized and then combined to obtain multiple options.In each option

a step-wise method was used.First

MEN was synthesized

targeting minimum total annual cost (TAC)of MEN by the superstructure-based approach.Second

the HEN whose data were obtained from the MEN in the first step was synthesized by solving modified HEN non-linear programming (NLP)based on HEN stage-wise superstructure.Then the TACs of two networks were summed up to obtain minimum TAC of the whole network in each option.Finally the TACs of all options were compared and the option with the lowest TAC of heat integrated mass exchanger network was chosen as the best one.Two examples were examined to demonstrate the feasibility and effectiveness of the method.
