摘要： 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.

摘要： Disclosed are systems and methods which provide a process stream comprising a gaseous component, capture the gaseous component from the process stream by an ionic liquid solvent of a separator, and recover a captured gaseous component from the ionic liquid solvent in a regenerator. A second gaseous component from the process stream may be captured by the ionic liquid solvent of the separator, and the second gaseous component may be recovered from the ionic liquid solvent in the regenerator. Alternatively, the second gaseous component from the process stream may be uncaptured by the ionic liquid solvent, and the uncaptured second gaseous component may be recovered from a membrane unit.
