The analysis of the Wicke-kallenbach dynamics experiments in semi-open arrangement showed that for single component and binary mixture permeation the effective diffusivities can be estimated from responses to step changes in partial pressure of components at the cell open side. The various techniques werw used to study single component permeation of nitrogen and binary nitrogen-methane mixture and to evaluate Maxwell-Stefan diffusion coefficients of the species. Comparison of the results from single component permeation and counter-current binary permeation is presented.
