This modeling framework implements standardized and transparent parametrization procedures. As an input it requires the pure compound critical temperatures and pressures along with the triple point densities and surface tensions, without further adjustment to ST data of mixtures. Its predictions of a major part of the existing surface tension data on asymmetric binary systems, including the aqueous solutions, in the entire available range of conditions, are discussed. The results demonstrate that the proposed approach is characterized by a remarkable overall robustness and reliability. However, the system toluene (1)–water (2) poses a clear limitation to its predictive implementation. Predictions of CP-PC-SAFT coupled with the generalized modified Yarranton–Satyro correlation for the recent...

The analysis indicates that the polar contribution of GC-PPC-SAFT has a negligibly small impact on predicting the high pressure data. Apparently, in the cases of the weakly- and non-associating compounds a major factor responsible for accuracy of the models at elevated pressures is the curvature of the dispersion contribution. At the same pressures CP-PC-SAFT tends to predict the lower values of densities and higher values of sound velocities. These predictions of CP-PC-SAFT are particularly accurate in the cases of slightly polar compounds with reliable values of the critical constants. Both models are capable of yielding only raw estimations of C P . Although CP-PC-SAFT has a clear advantage in predicting the available compressibility data, GC-PPC-SAFT is superior in qualitative estimating the isobaric thermal expansion coefficients. However the major advantage of GC-PPC-SAFT is the more accurate estimation of the vapor pressures away from the critical points.
