Abstract: One or more processes for stabilizing a hydrocarbon stream. An unstabilized hydrocarbon stream comprising C5+ hydrocarbons and including some butane, propane and ethane, may be passed to a first separation zone. The first separation zone has an increased operating pressure so that a residue gas stream recovered from the first separation zone requires minimal compression for further processing. A bottoms stream form the first separation zone is passed to a second, lower pressure separation zone which provides an NGL stream and a C5+ liquid hydrocarbon stream that is stabilized.

Abstract: Processes for separating a natural gas stream from a liquid hydrocarbon stream. After being cooled, a feed stream may be separated in a first separation zone, into a gaseous stream and a liquid stream. A portion of each stream may be passed to a heat transfer zone to sub cool and then passed to a second separation zone having a distillation or fractionation column. An intermediate separation zone may be used to flash a gaseous stream from the sub-cooled liquid stream. The fractionation column may be operated to include ethane in either a residue gas stream rich in methane, or in the liquid hydrocarbon stream.
