<p>The separation of gas mixtures in commercial sized adsorption systems is carried out with a carefully limited difference in loading of the adsorbed component on the bed between the start and the end of the desorption step. Under such conditions, each succeeding adsorption step will be carried out so that an adsorption/heating front is caused to advance sufficiently ahead of a slower moving cooling front that thus serves to cool only the feed end of the bed to the inlet gas mixture temperature. The heat of adsorption is thereby retained in the bed between these two fronts at a temperature tolerable to the gas mixture and to the adsorption bed and is available for the following desorption step.</p> |
