review text: The author examines diagonal approximations to Stefan-Maxwell equation for mass diffusion in multicomponent as mixtures. These approximations, like the Fickian diffusion approach, allow to decouple the full linear system by specifying the effective binary diffusion coefficients, thereby reducing significantly the computational costs. A new simplified diffusion procedure is constructed by minimizing the approximation error for diagonal approximations. The new model is shown to be more accurate than any other existing diagonal simplified diffusion model.
