Integrated high pressure NGL recovery in the production of liquefied natural gas |
摘要 |
Process for the recovery of components heavier than methane from natural gas, wherein the process comprises (a) cooling a natural gas feed to provide a cooled natural gas feed and introducing the cooled natural gas feed into an absorber column at a first location therein; (b) withdrawing from the absorber column a first overhead vapor stream depleted in components heavier than methane and a bottoms stream enriched in components heavier than methane; (c) introducing a methane-rich reflux stream at a second location in the absorber column above the first location; (d) separating the bottoms stream into a stream enriched in methane and one or more streams enriched in components heavier than ethane; and (e) introducing an absorber liquid comprising components heavier than ethane into the absorber column at a location between the first location and the second location.
