The process synthesis problem referred to as work and heat exchange networks (WHENs) asks to determine the optimal heat exchanger network intertwined with compressors, expanders, and valves, all integrated into one single network, such that streams with certain initial temperature and pressure attain their temperature and pressure targets at minimum cost. This article presents a procedure that obtains the globally optimal solution of Minimal WHEN systems using an enumeration scheme, using only a few subproblems, each one solved using mathematical programming to global optimality. Minimal structures feature one compression/decompression task and one heat exchange task per stream. In addition, we depart from the ideal gas assumption and use a cubic equation of state for stream properties. Finally, the approach allows for the use of turboexpanders. Four examples are presented to show the effectiveness and accuracy of the proposed method.

使用枚举的最小 WHEN 系统的全局最优设计

称为工作和热交换网络 (WHEN) 的过程综合问题要求确定与压缩机、膨胀机和阀门交织在一起的最佳热交换器网络,所有这些都集成到一个网络中,以便具有特定初始温度和压力的流达到其以最低成本实现温度和压力目标。本文介绍了一种使用枚举方案获得最小 WHEN 系统全局最优解的过程,仅使用几个子问题,每个子问题都使用数学规划求解到全局最优。最小结构的特点是每流一个压缩/减压任务和一个热交换任务。此外,我们偏离了理想气体假设,并使用三次状态方程来表示流特性。最后,该方法允许使用透平膨胀机。
