PROCESS TO SEPARATE NITROGEN AND METHANE ABSTRACT A process for more efficiently separating nitrogen and methane using a double column cryogenic rectification nitrogen rejection unit wherein feed is passed through a high pressure stripping column prior to the nitrogen rejection unit. As a result, higher pressure methane can be recovered with reduced compression requirements, and an upgraded feed to the nitrogen rejection unit enables more efficient separation.
