近年来,随着Matlab化工模拟技术的进步以及工业生产过程现代化的普及,人们对工业过程控制的自动化水平要求越来越高,以模型控制(MPC)为核心的先进控制技术在工业过程控制领域已经得到了极大的应用和发展.化工过程模型化是过程研究与开发、化工过程设计与分析、模型预测、系统工程、优化和控制以及生产计划和调度的基础.通过建立过程机理模型并进行计算机数值模拟,可以对丙烯聚合工程进行设计和分析模型预测、优化和控制等.MATLAB是一套功能强大的工程技术软件,被广泛用于自动控制、流体力学和数理统计等工程领域.工程技术人员通过使用MATLAB提供的工具箱.可以高效求解复杂的工程问题为优化聚合反应配方,探讨影响聚合反应的因素,实现对聚合反应转化速率的计算,为优化操作、优化控制奠定基础.因此这方面的研究对从事聚合反应工程的大学生、研究生、教学和研究人员、工程师都将有重要意义.
聚合反应工程中的计算所涉及的操作数据对象通常是数组,具体计算涉及到参数拟合、求积分、插值、解线性和非线性方程、解常微分和偏微分微分方程等.Matlab具有强大的数据组处理能力,本文是通过使用MATLAB提供的工具箱高效求解复杂的化学反应工程问题,对Hypol工艺连续式聚合反应工程求解、分析第一液相釜、第二液相釜和气相釜热传递过程,用于计算浆液浓度、平均停留时间,预测了熔融指数.

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.
