A widely used method for adsorption of solutes from liquid or gases employs a fixed bed of granular particles. The fluid to be treated is usually passed down through the packed bed at a constant flow rate. The situation is more complex than that for a simple stirred-tank batch process which reaches equilibrium. Mass-transfer resistances are important in the fixed-bed process, and the process is unsteady state. The overall dynamics of the system determine the efficiency of the process, rather than just the equilibrium considerations.
The concentrations of the solute in the fluid phase and of the solid adsorbent phase change with time and with position in ...
