Abstract: Based on the study of reactor network synthesis of types I and II reaction systems, the problem of reactor network synthesis of type III complex reaction system is solved. On the basis of stage characteristics of type III system, the new concepts of reaction system trace, instantaneous reactants, instantaneous products and instantaneous selectivity are defined, and a new strategy of segmented derivative analysis approach for reactor network synthesis is presented. The three-step strategy for reactor network synthesis of type III system is given. The Denbigh reaction and a 9-component reaction system are analyzed with the strategic segmented derivative analysis approach. The results prove that the analysis approach is simple and reliable. The optimal reactor network structure can also be obtained.
