Semi-Empirical Model of Toluene Transport in Polyethylene Membranes Based on the Data Using a New Type of Apparatus for Determining Gas Permeability, Diffusivity and Solubility

Original language description

Solubility, diffusivity and permeability of toluene vapors in low-density polyethylene (LDPE) membranes of various thicknesses at different temperatures 30, 40 and 50 degrees C in the range of relative vapor pressure were measured using new type of permeation apparatus. Moreover, special construction of the new cell enables determination of the permeant amount sorbed in the membrane in the steady state operation of vapor permeation. The simple semi-empirical model of toluene transport in a polyethylenemembrane based on relation between experimentally obtained effective diffusion coefficients and concentration dependent diffusion coefficients evaluated from experiments on a new permeation apparatus was proposed. The model enables estimation of toluenefluxes, sorption in the steady state of vapor permeation and concentration profiles in a polyethylene membrane from equilibrium sorption isotherms and effective diffusion coefficients.
