A process and system for removing contaminants from air comprises flowing a compressed air stream comprising water and carbon dioxide to a first adsorbent zone for contacting with a first adsorbent effective in the adsorption of water by flowing the air in a direction within the first adsorbent zone parallel with the axis of the first adsorbent zone to form a dry gas; flowing the dry gas from the first vessel to a second adsorbent zone comprising a second adsorbent disposed in a radial arrangement about the same axis to remove carbon dioxide. Regeneration of the adsorbent beds may be carried out independently.

A process for removing contaminants from a gaseous air feed stream comprising flowing said air feed stream to a first adsorbent zone and contacting said gaseous air feed stream with a first adsorbent displaced about an axis effective in the adsorption of water by flowing said gaseous air stream in a direction within said first adsorbent zone substantially parallel with the axis to form a dry gas; flowing said dry gas from said first adsorbent zone to a second adsorbent zone comprising a second adsorbent in a radial bed having an interior and an exterior and which is disposed in a radial arrangement about said first adsorbent zone and also about said axis; contacting said dry gas with said second adsorbent effective in retention of carbon dioxide in said second adsorbent zone by flowing said dry gas through said radial bed from the interior to the exterior of said radial bed.
