RATE AND DISPERSION FACTORS
RATE AND DISPERSION FACTORSThe performance of adsorption processes results in general from the combined effects of equilibrium or thermodynamic factors and rate factors. It is convenient to consider first thermodynamic factors. These determine the process performance in a limit where the system behaves ideally, that is, without mass transfer and kinetic limitations and with the fluid phase in perfect plug flow. Rate factors determine the efficiency of the real process in relation to the ideal process performance. Rate factors include heat- and mass-transfer limitations, reaction kinetic limitations, and hydrodynamic dispersion resulting from the velocity distribution across the bed and from mixing and diffusion in the …
