Abstract
A system for recovering nitrogen during regeneration of a treater, the system including an adsorbent bed downstream of the treater, wherein the adsorbent bed comprises an adsorbent operable to adsorb at least one impurity from a treater bed regeneration effluent stream comprising nitrogen to provide a nitrogen product having a higher nitrogen purity than a nitrogen purity of the treater bed regeneration effluent stream. A method for recovering nitrogen during regeneration of a treater is also provided.
