Abstract (en)
[origin: US2004244415A1] This process includes the following steps: (a) the feed natural gas (101) is introduced into a first distillation column (31) which produces, as top product, a pretreated natural gas (111), which pretreated natural gas (111) no longer contains practically any C6<+> hydrocarbons; (b) the pretreated natural gas (111) is introduced into an NGL recovery unit (19) comprising at least a second distillation column (49), so as to produce, on the one hand, as column top product, a purified natural gas (151) and, on the other hand, an NGL cut (15); and (c) the said liquefiable natural gas (161) is formed from the purified natural gas (151) resulting from step (b).
