摘要
基于基团贡献法的UNIFAC模型在缺少参数的系统预测中,具有很高的应用价值。但是随着对C4组分各种测量数据的积累和C4组分中存在的多种异构现象,其它活度系数状态方程更能准确处理该非理想体系。利用文献数据,结合Aspen Plus软件的数据处理功能,回归出C4组分和DMF间的Wilson参数,并在此基础上建立DMF法1,3-丁二烯工艺的全流程模拟,结果显示此方法具有很好的准确性。
The group contribution model in the predicting system that lacks parameters behaves well. However due to accumulating of C4 and various isomerism existed in the C4, other activity state equation can accurately process non - ideal system. Wilson parameter between C4 and DMF is regressed by using published literatures and Data Fit U-tility of Aspen Plus, and all process simulation of DMF and 1,3- Butadiene has been established. It is indicated that good result is obtained by using the above - mentioned method.
