Adsorption equilibrium data are commonly gathered at a fixed temperature and plotted or tabulated as capacity or loading versus the fluid-phase concentration or partial pressure for gases and vapors. This simplified-design model ignores both the intraparticle solid mass transfer resistance and the external fluid-film resistance directly. Adsorption column design procedure
Adsorption Column Design Procedure, The procedure for adsorption column could be found in book Unit operation Mc. As for my 3rd Year Design Project I was given a task to design a syngas production plant and towards the end of the process we are going to use the pressure swing adsorptionvacuum swing adsorption to remove the carbon dioxide. Therefore if you intend to adsorb 4000 kghr of air it means you will have to put that amount and NOT 2000 kghr into each of. Unbuffered lead solution with 100 ppm concentration was used in the experiment.
