More than 30 different thermodynamic models for the calculation of phase equilibria are available. In addition to the usual gE models and equations of state, it is also easy to add and use custom K-value models. Also, there are numerous special settings for special conditions (e.g. pointing correction at high pressures) or material systems (e.g. vapor phase association for acetic acid). And for the calculation of enthalpy, more than 10 models are available. The usual models are also provided for additional component data and mixing rules. With local thermodynamic settings, different models can be applied within the same flow sheet.
