摘要
萃取过程模拟优化是化工过程模拟计算的重要组成部分,其模块的开发是必不可缺的。为实现基于CAPE-OPEN标准的萃取塔单元模块,首先明确萃取塔的功能,对流率加和算法进行改进,建立萃取过程的数学模型;然后,采用C++语言与COM组件技术对萃取塔单元模块进行开发。通过测试芳烃抽提实例对所开发模块进行验证,经迭代计算后能够达到收敛精度。将各塔板温度、萃取相及萃余相流量、组成等计算结果同化工模拟软件Aspen Plus进行对比。结果表明,所开发的萃取塔单元模块可以准确计算塔内各平衡级的组成、流量和温度分布,从而验证所开发的萃取塔单元模块的计算结果是可靠的。
It is acknowledged that the simulation and optimization of extraction process is an important part of chemical process analog calculation, the development of its modules is essential. Firstly, the function of the extraction tower should be clarified. the mathematical model for the extraction process is established by modified the Sum-Rates Method. Secondly, The extraction tower unit module is developed by using C＋＋ language and COM component technology The development of the module is validated through test the aromatics extraction example, and the convergence accuracy can be achieved after iterative computation. The calculation results of the temperature, extraction phase and caffeinate phase flow rate, and composition of each plate are compared with the chemical simulation software Aspen Plus. The results show that the equilibrium stage of the compositions, flow and temperature distribution can be calculated accurately by the development of the extraction tower unit module. It is shown that the calculated results of the developed extraction column module are reliable.
