PERFORMANCE OF THE NONISOTHERMAL FIXED-BED ADSORPTION COLUMN WITH NON-LINEAR ISOTHERMS

The cell model approach for the analysis of nonisothermal fixed bed adsorption column has been presented under the assumption that adsorption is controlled by intraparticle diffusion and adsorption equilibrium is nonlinear. The numerical analysis has been carried out by the Runge-Kutta-Gill scheme. With the aid of a HITAC-8800 computer, the influence of controlling variables of the breakthrough curves and temperature curves has been made clear for such parameters as solid phase mass transfer coefficient, overall heat transfer coefficient at the column wall, length of bed and the equilibrium isotherms. A nonisothermal adsorption column can be designed adequately by applying the numerical method developed here according to the cell model approach. © 1979.
