Abstract The dew points of 40 multicomponent fluid mixtures including gas condensates, absorber oils, crude oils, synthetic aromatic heavy oils, and coal liquids were calculated using the method of continuous thermodynamics and the Patel‐Teja cubic equation of state. These multicomponent mixtures were characterized by a log normal distribution function in two variables: the boiling point and specific gravity in this work. Comparisons were made with the case when a single variable distribution function is employed and also with the method of Cotterman et al. In general, the new method leads to excellent predictions of both phase equilibria and liquid densities.
