For ABC ternary systems, where AB and AC are mutually soluble while BC is partially soluble, how should a thermodynamic model be chosen? According to the literature, for vapor-liquid equilibrium (VLE), Wilson is more appropriate for AB and AC ； Can this model be used for the ABC ternary liquid-liquid equilibrium (LLE)? Thank you very much.
NRTL or UNIQUAC
Then use Wilson, and compare it with the experiment
The Wilson model cannot describe LLE; it is recommended to use models based on NRTL or UNIQUAC, etc
Model calculation is one thing; what’s more important are experiments. I have seen impure acetaldehyde solutions, phenol solutions, as well as those that are layered
