4. Adsorption dynamics in an adsorber

Adsorption processes use adsorbers in which the fluid to be treated is in contact with adsorbents. A good understanding of the dynamic behavior of these adsorbers is crucial to the design and optimization of adsorption processes. These behaviors are highly complex and depend on the interactions between the fluid and the adsorbents, defined by adsorption (thermodynamic and kinetic), thermal and hydrodynamic properties. Consequently, it is very difficult to predict the behavior of industrial adsorbers without a minimum of small-scale experiments. To be able to dimension the industrial adsorber, it is interesting to be able to carry out dynamic adsorption of the same fluid on a small pilot, with a low flow rate. The treatment must be carried out under the same operating conditions (temperature, pressure, mixture composition, grain size, flow rate) on a fixed bed of a few grams of adsorbent....
