Integrert hoytrykks NGL-gjenvinning ved fremstilling av flytende naturgass

Process for the recovery of components heavier than methane from natural gas, wherein the process comprises (a) cooling a natural gas feed (1) to provide a cooled natural gas feed (35) and introducing the cooled natural gas feed into an absorber column (37) at a first location therein; (b) withdrawi...

Beschreibung
Zusammenfassung:	Process for the recovery of components heavier than methane from natural gas, wherein the process comprises (a) cooling a natural gas feed (1) to provide a cooled natural gas feed (35) and introducing the cooled natural gas feed into an absorber column (37) at a first location therein; (b) withdrawing from the absorber column a first overhead vapor stream (63) depleted in components heavier than methane and a bottoms stream (41) enriched in components heavier than methane; (c) introducing a methane-rich reflux stream (75) at a second location in the absorber column above the first location; (d) separating (43) the bottoms stream into a stream enriched in methane (45) and one or more streams (47,49,51) enriched in components heavier than ethane; and (e) introducing an absorber liquid (61) comprising components heavier than ethane into the absorber column at a location between the first location and the second location.
