In recent years, advances in technology with the Matlab chemical process simulation, as well as the popularity of modern industrial processes, the level of automation of industrial process control have become increasingly demanding, model control (MPC) as the core of advanced control technologies in the field of industrial process control has a great deal of application and development. Chemical process modelling is the process of research and development, chemical process design and analysis, the model predicts that the systems engineering, optimization and control, as well as the basis for production planning and scheduling. Through the process of establishing the mechanism model and computer simulation, the polymerization of propylene project design and analysis of model prediction, optimization and control. MATLAB is powerful engineering software, has been widely used in automatic control, fluid mechanics and mathematical statistics, and other engineering fields. Engineering and technical personnel using MATLAB tool box, can efficiently solve complex engineering problems in order to optimize the polymerization recipe, to explore the factors that affect the polymerization, the polymerization conversion rate calculation, and to lay the foundation for optimal operation, the optimal control. Research in this area in polymer reaction engineering students, graduate students, teaching and research staff, the engineers will have great significance.
Usually in the polymerization reaction engineering calculations for which the operating data object is an array, specific calculations related to the parameter fitting, quadrature, interpolation, solution of linear and nonlinear equations, solution of ordinary differential equations and Partial differential equations and so on. Matlab has powerful data processing capacity. This paper is efficient for solving complex chemical reaction engineering problems by using the toolbox provided by MATLAB, solving Hypo process continuous polymerization engineering analysis of the first liquid phase reactor, the second liquid phase reactor and gas reactor heat transfer process, the slurry concentration used to calculate the mean residence time, and predict the melt index.
