UNIFAC activity coefficient model is used to calculate composition derivatives needed in estimation of the thermodynamic factors that appears in the Maxwell-Stefan equation describing the diffusion in nonideal multi-component systems
and is compared with the NRTL
Wilson and UNIQUAC models. Results calculated by UNIFAC for several systems agree well with not only those predicted by NRTL and Wilson models but also some literature data.
