摘　　要： 将SRK状态方程与PHV、MHV2、WS和SR 4种不同的混合规则相结合进行汽液平衡计算 ,比较了在极性物系、复杂高压体系和多元物系中的计算偏差。结果表明 ,PHV混合规则的计算偏差最小 ,并且可以用二元系数据来计算多元系的汽液平衡 。 Four different mixing rules for the SRK-EOS were investigated for vapor-liquid equilibrium calculation The calculation deviations among polar systems, complex high pressure systems and multicomponent systems were compared. The results showed that the PHV mixing rule was of smallest deviation and dinary data could be used to calculate the vapor-liquid equilibrium of multicomponent systems. When being used in polar systems, the deviation was even smaller than that of activity coefficient models UNIFAC and NRTL.
