The effect of bed height on breakthrough curve analysis was studied by. The procedure for adsorption column could be found in book Unit operation Mc. Adsorption column design procedure.
Adsorption Column Design Procedure, The basic process configurations of the physical plant include upflow or downflow either under force of gravity or pump pressure with fixed or moving beds. The procedure offers a great flexibility in terms of gas velocity thus allowing process designers to be able to customize the lengthdiameter ratio of the adsorption column. A sensitivity analysis was also done to make sure the column could withstand changing conditions like temperature and contaminant concentration.

How To Size An Adsorption Column Before the adsorption bed is depleted the regenerated bed must be put into service and the roles are reversed. PSA operation includes1329 1 pressurization of the inlet gas over 3 atm 2 adsorption with inlet gas at high pressure 3 depressurization to atmospheric pressure releasing CO2 at the bottom of desorption column and 4 desorption CO2 gas from the adsorbent with purging gas at 1 atm. The ultimate in favorable isotherms is irrevers-ible adsorption where maximum adsorption is reached at very low partial pressures. In both approaches a breakthrough curve from the test column either laboratory or pilot scale is required and the column should be as large as possible to minimize side-wall effects.
