3. Adsorption and dynamic adsorbers
An adsorbent is generally implemented in the form of a filter, i.e. a fixed bed packed with particles (grains or extrudates) through which the air to be treated flows. The cognitive and dimensional approach to this type of reactor involves the study of fluid flow in the packing and knowledge of mass and heat transfer.
3.1 Flow. Pressure drop in a porous medium
As the fluid flows through the porous medium, the energy loss results in a pressure difference between the inlet and outlet of the adsorber. This pressure drop ΔP can be calculated by classical models, such as the Carman-Kozeny-Ergun model (cited by
