Application to binary mixtures of a group contribution SAFT EOS (GC-SAFT)

The results show that the group contribution (GC) method provides pure compound parameters that allow a satisfactory prediction of the binary mixtures. In several cases, the GC parameters yield even better results for binary mixtures than those adjusted directly on the pure compounds (specific parameters). This rather unexpected observation may be due to the fact that these parameters take more information into account than the specific ones.
