Abstract (en)
Natural gas (100) is liquefied and components heavier than methane are recovered by a process in which cooled natural gas (116) is separated into an overhead vapor (122) enriched in methane and a bottoms stream (134) enriched in the heavier components in a first distillation column (118) which utilizes a liquefied methane-containing reflux stream (127 + 138). This reflux stream may be provided by a condensed portion (126) of the overhead vapor (122) or a portion of totally condensed overhead vapor (122) that is subsequently warmed. The bottoms stream (134) may be separated (136) to provide one or more product streams, any of which are partially or totally withdrawn (C2, C3, C4) as recovered hydrocarbons. A stream of unrecovered liquid hydrocarbons (138) may be combined with said condensed portion (126) or said subsequently warmed portion.
