Applicability of the K(F)a(v) model in the prediction/simulation of the breakthrough curve of a fixed bed adsorber was studied through quantitative evaluation of the estimation error of the breakthrough curves calculated by the K(F)a(v) model with those calculated by the phenomenological rigorous adsorption process model. The evaluation was carried out on the basis of dimensionless equations of each model as a function of the Biot number and the parameters of adsorption isotherms used in the phenomenological rigorous adsorption process models. Influence of the non-linearity of the adsorption isotherm and the Biot number to the estimation error of breakthrough curves obtained by the K(F)a(v) model was clarified quantitatively. The application quality and/or degree of reliability of the K(F)a(v) model were clarified systematically.
