Abstract


This article to a domestic petrochemical enterprises of 50,000 tons / year HYPOL process polypropylene plant for the study of the process of polymerization section was focused research, simulation and dynamic simulation of the steady-state polymerization section were completed. Firstly, based on the generating function method to complete the polymerization section of the steady-state simulation, simulation has good results. Subsequent innovative with link analysis \Dynamic simulation of propylene polymerization process, developed a dynamic simulator. Of propylene polymerization section of the system analysis, the paper first based on the generating function method to establish the steady-state model of the polymerization process. The analog component is defined in the model, and using the equation of state of the PC-SAFT main thermodynamic model; reasonable simplifying assumptions on the process, the two liquid phase reactor and a gas-phase fluidized-bed reactor is defined as all ideal continuous stirred tank reactor. Coordination of propylene polymerization kinetics model focus is difficult, the paper first established based on the mechanism of propylene polymerization kinetics model and debugging determine the kinetic parameters of single active site, and finally generating function method of polymerization the characteristics of the material to characterize the eventual establishment of the the entire polymerization section of the steady-state model, and simulation results are analyzed. Generating function method \, making the calculation is considerably simplified. Therefore, this article \\section analysis \Created the \has great application prospects.
