    Notizen: Volumetric data on gas mixtures and vapor-phase data for gas-liquid equilibria have been correlated within the framework of the theory of corresponding states. An expression based on the London potential for dispersion forces was used to compute characteristic temperatures for various binary systems, and a correlation was developed relating these temperatures to the polarizabilities, ionization potentials, and critical volumes of the pure components. The correlation shows how the molecular shape of a liquid affects its vapor-phase solubility. With the help of this correlation it is possible to make very good predictions of such gas-liquid equilibria as are required in high-pressure distillation, absorption, and petroleum hydrofining operations.

    Regular solution theory for gas-liquid solutions (1958)
    Hoboken, NJ : Wiley-Blackwell
    AIChE Journal 4 (1958), S. 269-272

    Notizen: Regular-solution equations developed by Hildebrand and others are useful for obtaining semiquantitative estimates of phase equilibria in nonpolar systems. These equations, however, do not take into account the volume change on mixing and therefore require modification for solutions of gases in liquids. The required modifications are presented in this paper, and the resulting equations give reasonable estimates of the solubilities of gases and of the temperature coefficient of solubility. In the modified form the regularsolution theory may be used to estimate gas-liquid phase equilibria at high pressures.

    Fugacities in high-pressure equilibria and in rate processes (1959)
    Hoboken, NJ : Wiley-Blackwell

    Details

    Notizen: 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.

    Volumetric properties of nonpolar gaseous mixtures (1958)
    Hoboken, NJ : Wiley-Blackwell
    AIChE Journal 4 (1958), S. 430-435 
    Details

    Notizen: Volumetric data of nonpolar gaseous mixtures are analyzed in terms of the theory of corresponding states. Special attention is given to an analysis of the second virial coefficient and to the calculation of pseudocritical constants.Second virial coefficients are calculated from experimental data for ten binary systems. These coefficients, with those previously published, are correlated by means of a generalized equation involving three parameters for each component: the critical volume, the reduced temperature, and the acentric factor.Equations are derived for the pseudocritical temperature and pressure of mixtures. These equations are considerably more accurate than those given by Kay's rule. Because of the complexity of the proposed equations for the pseudocritical parameters, a simplified pseudocritical method is presented which is sufficiently accurate for most chemical engineering purposes, especially at reduced temperatures exceeding 1.3.

    Solubility of liquids in compressed hydrogen, nitrogen, and carbon dioxide (1959)

    Notizen: The vapor-phase solubilities of carbon tetrachloride, iso-octane, toluene, and n-decane were measured in compressed hydrogen, nitrogen, and carbon dioxide at 50° and 75°C. and at various pressures between 20 and 90 atm. The virial equation of state was used to describe the volumetric properties of the vapor mixtures, and the second virial cross coefficients were evaluated from the solubility data. The results indicate that the vapor phase departs from ideality very quickly for these systems as the pressure increases, particularly at pressures greater than 10 atm.
