摘要
评价了用聚合物浓溶液气液平衡估算的9种基团贡献法的预测模型,即ASOG,UNIQUAC,UNIFAC,UNIFAC-FV,F-H,Elbro-FV,GK-FV,GC-FloryEoS和GCLFEoS的预测能力,建议使用UNIFAC-FV,Elbro-FV,GK-FV,GC-FloryEoS(有待简化)4个模型来预测聚合物浓溶液的气液平衡。并展望了其今后的发展趋势。
The group-contribution-based methods,which include ASOG,UNIQUAC,UNIFAC,UNIFAC-FV,F-H,Elbro-FV,GK-FV,GC-Flory EoS and GCLF EoS model on vapor-liquid equilibria(VLE)in concentrated polymer solutions and its trend to development in the future were reviewed with 50 references.
