The implementations published on this website support a variety of different thermodynamic models. Many thermodynamic models are supported, like, e.g. NRTL or UNIQUAC to describe the activity coefficients, or the extended Antoine-equation to describe the vapor pressure.
The required parameters of the thermodynamic models can be provided manually. The demanded command syntax is documented here. The model-equations are taken from AspenPlus ® . Stoff3 represents a parsing tool which reads the parameters belonging to the supported model-equations from an AspenPlus ® report-file (.rep) automatically, and converts it to the desired command syntax. A brief guide to Stoff3 can be downloaded here.
Stoff3 was developed by Alexander Dohr during a trainee exchange from April, 12th to June, 29th, 2012 in cooperation with Arno Saxena. The work was supervised by Christian Redepenning.
