Abstract (en)
[origin: WO2010042266A1] The invention relates to a process for producing a helium-enriched vapor stream, a methane- enriched vapor stream, and a liquid stream enriched in hydrocarbons heavier than methane from a pressurized, multicomponent, multiphase stream comprising methane (C1), helium (He) and hydrocarbons heavier than methane (C2+). The process includes cooling the multiphase stream to produce at least one vapor stream enriched in helium and at least one liquid stream, withdrawing at least a portion of the at least one vapor stream as a helium- enriched product stream, passing at least a portion of the at least one liquid stream to a demethanizer, withdrawing from the demethanizer a vapor enriched in methane (C1), and withdrawing from the demethanizer a liquid enriched in hydrocarbons heavier than methane (C2+).
