摘要：

This paper proposes a flexible heat exchanger network model for multiple factories and periods, aiming to solve the problems of inflexibility and inability to adapt to changing production environments in existing heat exchanger network designs. The model consists of two sub-models: the first sub-model uses a multi-factory superstructure heat exchanger network model to solve the heat exchanger network structure for each period, and the second sub-model solves the multi-period heat exchanger network design for each factory with the annual total cost as the objective function. In each factory, all heat exchangers are shared and the network structure can be easily changed to meet the heat exchange demand by adjusting the logistics flow when the period or conditions change. The case test shows that the minimum total annual network cost is 210919.4 USD·a-1, and 13 shared heat exchangers need to be installed, including 6 in factory 1, 4 in factory 2, and 3 in factory 3. The flexible heat exchanger network model proposed in this paper has the characteristics of high design flexibility and strong ability to respond to changes in production environments, providing industrial enterprises with a more intelligent and efficient heat exchanger network design method. © 2023 Chemical Industry Press.
