A review of methods is presented which allow to determine the P-V-T behaviour of gas mixtures. This review is based on the computations performed for about 2 200 P-V-T-X data of 12 binary mixtures. The method of combination of the equation-of-state constants, the Joffe method and the modified Bartlett rule proved to be the most suitable.

Critical Constants

Various truncations for the virial series of a binary fluid mixture of additive hard spheres are used to analyze the location of the critical consolute point of this system for different size asymmetries. The effect of uncertainties in the values of the eighth virial coefficients on the resulting critical constants is assessed. It is also shown that a replacement of the exact virial coefficients in lieu of the corresponding coefficients in the virial expansion of the analytical Boublík–Mansoori–Carnahan–Starling–Leland equation of state, which still leads to an analytical equation of state, may lead to a critical consolute point in the system.
