Modeling
The same parameters were used to predict the P-x diagrams for alkane +
perfluoroalkanes symmetric mixtures with low molecular weight components as CF4 +
CH4 and C4F10 + C4H10 (Thorpe and Scott, 1956). Figures III.29 and III.30 show the
predictions given by the soft-SAFT EoS compared with experimental data found in the
literature. Although in these cases higher deviations were obtained, with an average over
prediction of about 10%, the results are acceptable since only one binary parameter
adjusted for a mixture at very different thermodynamic conditions from the ones observed
for these mixtures. Also, the molecular parameters for the pure components of these
mixtures already presented a significant discrepancy from the pure experimental data as
discussed before.
