摘    要:以寻求串级萃取最低生产成本的工艺条件为最优化目标,通过将萃取工艺参数与随之会发生变化的生产成本关联,建立了分馏萃取最低成本优化萃取比方程。为简化计算,推导出萃取段、洗涤段最低成本萃取比方程。如果不考虑酸碱消耗的成本变化,推导出的简略方程其优化目标与现有最优萃取比方程相一致,计算值相近。建立的最低成本优化萃取比方程及其优化目标发展了现有最优萃取比理论。

Abstract: Based on the optimization goal searching for extraction parameters of minimun production cost, a novel equation for calculating optimized extraction factor of minimum production cost in fractional extraction was proposed. For short-cut calculation, new equations for determining the optimized extraction factors of minimum production cost in both the extraction and scrubbing sections were derived from above novel equation. These equations and theory have further developed the theory on equations of optimized extraction factors.
