FREMGANGSMAADE OG APPARAT TIL FJERNELSE AF NITROGEN FRA NATURGAS, INTEGRERET MED NATURGASVAESKEUDVINDING |
摘要 |
A process is set forth for the recovery of methane, nitrogen and natural gas liquids (C2+) from a natural gas feed stream wherein the recovery can be made at high pressure by the integration of a nitrogen rejection stage including a heat pump driven distillation column and a natural gas liquids stage. Nitrogen can be rejected over a wide range of nitrogen concentration (approximately 1 to about 80%) of the feed stream. |
