Abstract
Provided are apparatus and systems for performing a swing adsorption process. This swing adsorption process may involve passing streams through adsorbent bed units to treat the feed stream to form a stream that complies with nitrogen rejection specifications. The process may involve using at least a portion of the nitrogen rejection process product streams as a purge for the swing adsorption process.
