Process to separate nitrogen and methane. |
摘要 |
<p>A process for more efficiently separating nitrogen and methane using a double column cryogenic rectification nitrogen rejection unit (106,108) wherein feed is passed through a high pressure stripping column (102) 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. </p> |
