摘要
本文针对 UNIFAC 基团贡献法中交互作用参数变化对活度系数的影响,建立了灵敏度分析模型,根据此模型在 IBM-PC/XT 机上分别试算了大连石油七厂减二线、减三线抽出油与糠醛体系的活度系数灵敏度,从而对此模型的实际应用作出了估计。
A model of sensitivity analysis for activity coefficients from UNIFAC is suggested.Six
interaction parameters of four groups in furfural extract oil system have been tested.Re-
sults show that the sensitivities(the relative error of the activity coefficient of oil)of most
interaction parameters are less then 5%.
