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.

A process for stabilizing a liquid hydrocarbon stream, the process comprising:
- stripping a residue gas stream from an un-stabilized hydrocarbon stream in a first separation zone, the first separation zone operating at a pressure between 2,482 kPa and 3,034 kPa and providing a bottoms liquid stream comprising C3+ hydrocarbons;
- compressing the residue gas stream in a compression zone to provide a compressed residue gas stream having a pressure between 6,412 kPa and 7,377 kPa, the compressed residue gas stream comprising light hydrocarbons;
- and
- separating the bottoms liquid stream in a second separation zone operating at a pressure between 993 kPa and 1,489 kPa, the second separation zone being operated at a lower pressure than the first separation zone, the second separation zone providing a C3/C4 liquid product stream and a stabilized C5+ liquid hydrocarbon stream.
A process for stabilizing a liquid hydrocarbon stream, the process comprising:
- passing an un-stabilized hydrocarbon stream to a first separation zone, the first separation zone being operated at a pressure between 2,482 kPa and 3,034 kPa and configured to separate the un-stabilized hydrocarbon stream into a residue gas stream and a bottoms liquid stream comprising C3+ hydrocarbons;
- passing the residue gas stream to a compression zone configured to compress the residue gas stream and provide a compressed residue gas stream having a pressure between 6,412 kPa and 7,377 kPa, the compressed residue gas stream comprising methane, ethane, and propane;
- and
- passing the bottoms liquid stream from the first separation zone to a second separation zone, the second separation zone being operated at a pressure between 993 kPa and 1,489 kPa, which is lower than pressure in the first separation zone, the second separation zone configured to separate the bottoms liquid stream a C3/C4 stream and a stabilized C5+ liquid hydrocarbon stream.
