A non‐linear model of an open flow adsorption process

Abstract

AbstractA probabilistic model is developed that describes the dynamics of adsorption in open flow reactors in the case of non‐linear adsorption kinetics. The model accounts for the movement of solute molecules in the liquid phase, for the exchange of solute molecules between the liquid and outer layer (or compartment) of the solid phase and for movement of solute molecules between the outer and inner layers of the solid phase. From this model, one can predict the concentration of solute molecules in the exit stream of the reactor (breakthrough curve) over time. The model was applied to breakthrough curve data for trichloroethylene adsorption from water onto activated carbon. Model prediction was in good agreement with experimental data.
