基于MATLAB的连续重整装置模拟仿真平台

Development of simulation platform based on MATLAB for continuous reforming unit

以连续催化重整装置为研究对象,在对其流程及反应机理的研究基础上,利用MATLAB开发了一套基于图形用户界面(GUI)的连续重整装置模拟仿真平台软件。采用结构化设计方法,将平台划分为过程模型、输入/输出、物性计算、参数估计、过程模拟、灵敏度分析、过程优化等7个子模块,并从这几方面介绍了该平台软件的功能和实现方法。平台能够对重整装置内部基本流程进行稳态模拟,并具有灵敏度分析、过程优化等功能。针对国内某炼油厂连续重整装置的模拟结果与实际值吻合较好,表明了该平台软件的有效性。

The research object is the Continuous Catalytic Reforming（CCR） unit.On the basis of the study of its process flow and reaction mechanism,a simulation platform of CCR unit with Graphical User Interface（GUI） is developed based on MATLAB.By using a structured design method,the platform is divided into seven sub-modules,including process model module,input/output module,properties calculation module,parameter estimation module,process simulation module,sensitivity analysis module and process optimization module,from which an introduction of the platform＇s function and implementation is made.The platform could be used in performing steady-state simulation of the basic process of CCR unit,as well as sensitivity analysis and process optimization.A domestic refinery reformer is simulated on the platform, and the effectiveness of the platform is demonstrated by the fair agreement between the calculated results and the actual operating data.
