The prediction of azeotropic behavior and saturated liquid densities in the carbon dioxide‐ethane system

A study of the volumetric and phase behavior of binary systems. Part II. Vapor‐liquid equilibria and azeotropic states of propane‐perfluorocyclobutane mixtures

“…It has been shown earlier (Teja, 1978) that values of tfj calculated from correlations of critical and azeotropic states and saturated liquid densities (Teja, 1975) agree with each other and with values obtained from a correlation of the properties of chemically similar systems (Genco et al, 1980). It is convincingly demonstrated here that a value of obtained from a correlation of one property may be used for the prediction of other properties.…”

“…Equation 4, of course, holds only for azeotropic states. For the general vapor-liquid equilibrium problem, two quantities (T and P in this work) must be specified, and the following equations: In the calculations presented below, the equations for the pressure and for the fugacities were obtained using the extended form of the corresponding states principle with methane as the reference fluid (Teja and Rowlinson, 1973;Teja and Kropholler, 1975;Teja 1975. The method requires only the critical properties and acentric factors of the pure fluids as input parameters.…”

A study of the volumetric and phase behavior of binary systems. Part I. Critical properties of propane‐perfluorocyclobutane mixtures

“…The critical states measured in this study have been used to extensively test and develop an extended form of the corresponding states principle (Teja and Rowlinson, 1973;Teja and Kropholler, 1975;Teja. 1975Teja.…”

“…7"crr ^cm /cf^el (6) ^cm (7) and the mixing rules where the binary Interaction coefficient is an adjustable constant which must be obtained from experimental data on the mixture. It has been shown earlier ( 5) that values of calculated from correlations of critical and azeotropic states and saturated liquid densities (6) agree very well with each other, at least for mixtures of the lower molecular weight -alkanes and C02.…”
