Abstract:  With the nature of hybrid system for an oil refinery, the modeling of oil refining system is one of the most difficult problems in operating a refinery process. For the convenience of analysis of such a system, a controlledcoloredtimed Petri net (CCTPN) model is proposed for modeling crude oil operations. The CCTPN is extended to model dualpipeline crude oil transportation system with high/low fusion point oil. With a variety of practical production constraints, especially the high fusion point oil transportation constraints, the properties of the system are analyzed. Then, with a modular modeling approach and by decomposing the system into several subproblems, a Petri net model is developed such that the system is modeled in a hierarchical way, making the model compact. With this model, the system behavior can be effectively analyzed. Moreover, it can be used as an assistant tool for verifying the logistics information and shortterm scheduling.
