锆铪萃取分离系统参数的多目标优化决策

Multiobjective Optimum Decision of Technological Parameters for Separating Zr from Hf by Solvent Extraction

本文对叔胺从硫酸水溶液中萃取分离锆、铪的流程系统参数,用随机寻优法分别进行了单目标函数和多目标函数的优化算法研究,并对两种方法进行了对比。对比结果表明,多目标优化决策明显胜过单目标优化方法。

The paper describes two kinds of optimum methods which use single-objective func- tion and multiobjective function,respectively.The technological parameters of the system,which is designed to separate Zr from Hf in the solution sulphuric acid by solvent extraction,have be optimized with them.The computational results show that the multiobjective optimum decision is better than single-objective method.
