An Innovative Approach for Adsorption Column Modeling

An new methody for physical and chemical adsorption modeling in column apparatuses is presented. A convection-diffusion model is obtained in the approximations of the continua mechanics, where the mathematical point is equivalent to the medium elementary volume which is sufficiently small with respect to the column volume and at the same time sufficiently large with respect to the intermolecular volumes of the medium. The created convection-diffusion type model allows performing qualitative analysis of the process and obtaining the effect of the velocity radial nonuniformity in the column. An average concentration model is applied for quantitative description of physical and chemical adsorption in the column apparatus. The methods for model equation solutions and model parameter identifications are described.
