Notes:
This work considers the importance of vapor-phase nonideal mixing in high-pressure equilibrium and rate-process calculations. New techniques are presented for calculating vapor-phase fugacity coefficients in nonideal mixtures.The equilibrium properties of gaseous mixtures are represented by a virial equation of state which is adequate for the vast majority of chemical engineering problems. Techniques based on an extension of the corresponding-states theory are given for estimating the various coefficients appearing in the equation of state; these estimates appear to be reliable for a large variety of nonpolar or weakly polar systems. Techniques based on the theory of intermolecular forces are also presented for polar systems and for a limited class of mixtures containing hydrogen-bonding components. The proposed methods of calculation are illustrated by a large variety of problems occurring in common chemical engineering calculations, and it is shown that failure to correct for vapor-phase nonideal mixing can, in some cases, lead to very large errors.
