In Part I of this work, the synthesis of minimal heat exchanger networks using the isothermal mixing stage‐wise superstructure was presented. In this Part II, an extension of the algorithm presented in Part I is made to consider networks that allow multiple solutions regarding heat allocation, that is, they have energy loops where heat loads can be rearranged without changing the overall energy consumption. We extend the strategy of our Part I to use a set of nested loops to enumerate the number of units, the structure of matches, the energy consumption, different values of exchanger minimum approximation temperature (EMAT), and different locations where EMAT is active. All the models used are linear and are aided by capital cost evaluations. As in Part I, we claim global optimality based on our conjectures. Literature examples are solved to show the effectiveness of the algorithm.

热交换器网络的全球最佳综合。第二部分：非最小网络

在这项工作的第一部分中，介绍了使用等温混合分段上部结构合成最小换热网络的方法。在第二部分中，对第一部分中提出的算法进行了扩展，以考虑允许在热量分配方面有多种解决方案的网络，也就是说，它们具有能量循环，可以在不改变总能耗的情况下重新安排热负荷。我们扩展了第一部分的策略，以使用一组嵌套循环来枚举单位数量，匹配结构，能耗，不同的交换器最低近似温度（EMAT）值以及EMAT处于活动状态的不同位置。所有使用的模型都是线性的，并辅以资本成本评估。与第一部分一样，我们根据猜想主张全局最优性。
