To solve the realizability problem of initial state of crude oil operations in refinery for systems with two transportation pipelines, based on a Petri net model for crude oil operations, this paper analyzes the process that, for an given order of high fusion point crude oil, the system can switch from a steady state to the required initial state condition. Then, with the control theory, the switching process between different states is adjusted such that the required initial state conditions could be satisfied. This makes that the technique proposed in the paper can be applicable to practice. Finally,a real industrial case is given to illustrate the proposed method.
