摘要 : This paper demonstrates that the two excess Gibbs free energy G~E models with temperature-dependent parameters in the modified Huron-Vidal first-order (MHV1) mixing rule allow the Peng-Robinson equation of state modified by Stryje... 展开 This paper demonstrates that the two excess Gibbs free energy G~E models with temperature-dependent parameters in the modified Huron-Vidal first-order (MHV1) mixing rule allow the Peng-Robinson equation of state modified by Stryjek and Vera (PRSV) to be used for calculation of vapor-liquid equilibria over wide ranges of temperature and pressure. Good results are obtained for strongly non-ideal binary and ternary systems. 收起
