The paper introduces a new iterative sequential method for optimal heat exchanger network synthesis, that relies on an assignment problem. This method considers the splitting of hot and cold process streams, and uses a decomposition that fixes the split fractions for process streams at each subproblem. We apply this method to several heat integration problems to demonstrate its performance and efficiency. It is also compared with stage-wise superstructure optimization using mixed-integer nonlinear programming.

通过顺序分流的工艺流程优化热交换器网络的综合

本文介绍了一种基于分配问题的最优热交换器网络综合的新的迭代顺序方法。该方法考虑了热和冷工艺流的分离，并使用分解方法固定了每个子问题上工艺流的分离馏分。我们将此方法应用于几个热集成问题，以证明其性能和效率。它也与使用混合整数非线性规划的阶段式上部结构优化进行了比较。
