Predictive Model for Design of Fixed-Bed Adsorbers: Parameter Estimation and Model Development
Publication: Journal of the Environmental Engineering Division
Volume 104, Issue 2
Abstract
A predictive mathematical model for fixed-bed adsorber design which incorporates both liquid and solid phase resistances to mass transfer is formulated; numeric solutions are described and checked for accuracy. Laboratory bench scale studies used to estimate model parameters independently from adsorber break-through profiles are described, and experimental results presented. The bench scale tests involve both adsorption rate and isotherm measurements that are used to determine isotherm equation parameters and surface diffusion coefficients for model calibration. Liquid-phase mass transfer coefficients for fixed-bed operation are obtained from literature correlations; parameter values used for model calibration are presented. This paper sets the stage for single- and multi-component model verifications to be presented in two subsequent papers.
