Abstract
Carbon monoxide (CO) is removed from a nitrogen and CO containing gas stream such as feed air to an air separation process for recovery of a nitrogen product gas stream or a nitrogen product gas stream from an air separation process by adsorbing CO from said gas stream before or after separation of oxygen from said gas stream to produce a product gas stream containing less than 5 ppb of CO by contacting said gas stream With a solid adsorbent such as a Mn, Fe, Ni, Cu, Ag, Pd, Co, Pt or Au exchanged zeolite and periodically regenerating the adsorbent by desorption of CO therefrom under a flow of regenerating gas, and, if said gas stream is said feed air, separating oxygen therefrom to produce said nitrogen product.
