PC-SAFT

See also: simplified PC-SAFT

PC-SAFT is one of the latest equation of state. It is based on statistical mechanics, and the pure component parameters are obtained by fitting to vapor pressure and density data. This means that it will often get a very good fit to these properties but a poor fit of the critical point.

It has proven to be a strong model that combines with the associating therm and is capable of modeling very complicated systems.
