A predictive mathematical model for fixed-bed adsorber design that incorporates both liquid and solid phase resistances to mass transfer is verified for four different single-component systems under normal operating conditions. The adsorbates chosen for model verification were selected on the basis of representing a broad range of diffusive and adsorptive properties. Mass transfer limitations for the adsorbates vary from primarily intraparticle mass transfer resistance to primarily liquid-phase mass transfer resistance, and adsorption capacities vary over an order of magnitude. The general agreement between model predictions and fixed-bed performance under a wide variety of conditions confirms the model validity for predicting single-component adsorber behavior. Related papers by the writers describe model development, parameter estimation, and multicomponent model verifications.
