The amount of material adsorbed within a bed depends both on position and time. The amount of adsorbent needed in the absorber is determined by the equilibrium data, which in turn determines the key dimension and operation time for the process. So modelling of experimental data from adsorption processes is a very important means of this is the simplest adsorption isotherm in which the amount of surface adsorbate is proportional to the thus, the equilibrium adsorbate concentrations in the liquid and adsorbed phases are related to the.
