For the molar flow rate over the phase boundary, the chemical potential Δ μ is the driving force. In order to relate the driving force to the composition gradient Δ x, a correction is needed which is provided by the thermodynamic factors Γ. For the liquid phase, Γ is obtained by the derivation of the activity coefficient with respect to the composition. Taylor and Kooijmann [1] provided this derivation for the Wilson model, the NRTL model and the UNIQUAC model. Those three models are implemented in this package.
