Abstract
A practical method is presented by which the diffusion coefficients and free volume parameters can be obtained from steady state pervaporation experiment of single components. The method consists of fitting a numerical solution of the diffusion equation to experimental pervaporation data. The main principle of this method is based on Fujita's free volume theory and Flory-Huggins thermodynamics. The simulation and calculation of permeability using the diffusion coefficient determined by this method show excellent agreement with experimental data. This means that the new method can be provide practical values of diffusivity data which are applicable to the pervaporation process.
