An expression for the excess Gibbs energy of expandable liquid mixtures, such as liquefied gas mixtures, is obtained by considering the effect of molar volume change on the structure of a solution. A new equation is derived through the introduction of two limiting states: the close-packed and hypothetical expanded states. From this model, the deviation of the excess Gibbs energy from the close-packed state is determined by hole fraction and solution structure parameter. The model, which requires only binary parameters, was tested on vapor-liquid and liquid-liquid equilibria of various mixtures including liquefied gas mixtures, and gave better data representation than the UNIQUAC model.
