Matlab与Aspen Plus软件交互实现和应用
|
摘要
Aspen Plus是运用最为广泛的化工流程模拟软件之一,能够为新工艺设计、装置改造提供可靠的定量数据分析支持。但随着化工新技术的发展,单一的Aspen Plus软件无法完全满足用户的全部需求。将拥有不同功能的软件进行集成,是拓宽Aspen Plus软件功能的有效途径。Matlab是一款先进的数值求解软件,拥有强大的数值计算和模型开发能力。本文探讨了Matlab与Aspen Plus软件之间的两种交互方式。第一类是基于Active X技术,实现在Matlab环境下调用Aspen Plus模拟数据,并控制软件运行,显著增强Aspen Plus的数据处理和优化能力。第二类是以Excel作为Matlab与Aspen Plus软件的桥梁,实现了基于Matlab的Aspen Plus自主用户模型开发,由于Matlab语言的友好性,该方法能够降低Aspen Plus模型开发的难度,拓宽软件适用范围。以渗透汽化/精馏集成分离乙醇水溶液为例,对两种集成方式的实现做了详细说明。结果表明,两种集成方式都有效可行,并有着各自的优点及适用范围,通过软件集成有效地拓宽了Aspen Plus的模拟与分析能力。
Aspen Plus is one of the most extensively used process simulation software, which can provide reliable data analysis for new process designs and plant improvement. However, with the rapid development of new chemical technologies, Aspen Plus cannot meet all the requirements of the users. The software integration is an effective method to extend the functionality of Aspen Plus. Matlab is an advanced computing software for high-performance numeric computation and model development. In this work, we report the two different integration methods between Matlab and Aspen Plus. The first method realize the calling/modifying the simulation data of Aspen Plus in the Matlab environment based upon the Active X technology. It significantly enhance the data processing and optimization ability of Aspen Plus. The second one links Matlab and Aspen Plus by Excel in order to realize the user model development based on Matlab. Because of the convenience of the Matlab language, this method can reduce the complexity of model development and extend the applications of Aspen Plus. The pervaporation/distillation process for the purification of aqueous ethanol exemplified the realization of two integration methods. The results show that both integration methods are effective and applicable, yet each one has their own advantages and corresponding scope. In a word, the software integration can enhance the simulation and analysis ability of Aspen Plus.
