多厂热集成中间介质温焓特性形成与分解机理研究

In order to achieve high efficient use of energy, the multiple plant heat integration through intermediate media are studied. Graphical method is used to reveal the insights of the interaction between the whole system and each local source or sink plant. The theoretical optimal composite curve of the intermediate media is constructed. The composite curves of intermediate media under different connection patterns are developed, and their thermal characteristics are studied. Through the interaction between the theoretical optimal composite curve and the fitting curve of the intermediate media, the original composite curve is formed. Then the composite curve of the intermediate media is decomposed to determine the optimal connection patterns across plants and also the corresponding optimal parameters. The system integration theory concerning both global and local performances will be developed. The project will deepen and extend the theory of process integration and the corresponding industrial applications.
