A rigorous method for predicting the critical properties of multicomponent systems from an equation of state

Abstract This paper shows how the rigorous critical state criterion enunciated by Willard Gibbs can be used with a recently formulated two‐parameter equation of state to obtain an analytical solution to the problem of predicting the critical properties of defined multicomponent mixtures. Comparisons are made between predicted and experimental values for several systems containing paraffin hydrocarbons and related materials.
