摘要
焓超额焓是化学工业中混合与分离过程的重要热力学性质。由于超额焓的实验测定比较困难且不具有连续性；因此，国内外都对混合物超额焓的理论计算进行了大量的研究。同时，状态方程法在混合物超额焓的计算中也得到日益广泛的研究。计算体系也从常压体系扩展到高压体系以及...
The simplified method recently proposed by Qu and Liu was extended to correlate excess enthalpies of highly asymmetric binary systems.In this approach,FRKS equation of state was used,and Lij(T,x)function was applied to provide statedependent L12 values for every point calculated.Twentyfour binary systems were selected for the test.The calculated results show that this method can improve significantly the calculation of excess enthalpies of highly asymmetric binary systems,being simple and reliable.
