Song R., Wang Y., Feng X., 2016, Participant Plants and Streams Selection for Interplant Heat Integration among Three Plants, Chemical Engineering Transactions, 52, 547-552.
Interplant heat integration is an efficient way of energy saving for industry zones. In past few decades, many researches of this topic were proposed, which brings significant energy savings. However, in many previous studies, either all process streams or waste heat source/sink of individual plants were used for integration. This paper introduced a new selection strategy of participant plants and streams before integration, which can reduce the number of participant streams and calculation burden while the energy targets almost keep unchanged. The proposed method can consider both pinch and threshold problems. The parallel structure is selected for integration between three plants, since it can always achieve the largest energy saving than split and series structures and it might be more reliable when considering flow rate or temperature fluctuation in individual plants. A case study is used to show the effectiveness of the strategy.
