Abstract: To study the strong coupling among energy flow, material flow and information flow, as well as the hybrid nature of continuous and discrete coexist in the process industry, a methodology called Component based Hybrid Petri net (CpnHPN) was proposed based on the extension of hybrid, controlled and colored Petri net. With object-oriented as ideas and provided the precise description of energy flow, material flow and information flow, CpnHPN supported a multi-level reconfigurable modeling method by adopting the component-based principles. The modeling architecture and semantic specification of CpnHPN were described in detail. The process for chlorine production was taken as an example to reveal the practical value of the proposed approach, and the corresponding simulation result was provided by Dymola software.
