Definitions
- the invention relates to a method of processing and separating a multiphase well effluent mixture.
- Such a method is known from OTC paper 17399 "Subsea Gas Compression - Challenges and Solutions” presented by R.Fantoft at the Offshore Technology Conference held in Houston, USA on 2-5 May 2005 and from International patent applications WO30/033870, WO03/035335 and WO 2005/026497.
- the method known from WO2005/026497 comprises: - transferring the multiphase well effluent mixture via a multiphase well effluent flowline to a gas liquid separator in which the multiphase well effluent mixture is separated into substantially gaseous and liquid fractions; - transferring the substantially liquid fraction into a liquid flowline in which a liquid pump is arranged;
- liquid in the liquid flowline may be cooled and recycled into the multiphase well effluent flowline, but in case the well effluents are substantially liquid, then the gas compressor may be substantially solely fed with recycled gas, so that the influx of substantially liquid well effluents and of recycled cooled liquid is inhibited.
- a method of processing and separating a multiphase well effluent mixture comprising: - transferring the multiphase well effluent mixture via a multiphase well effluent flowline to a gas liquid separator in which the multiphase well effluent mixture is separated into substantially gaseous and liquid fractions;
- recycled gas is contacted with liquid by injecting recycled gas into a liquid filled section of the gas liquid separator.
- the gas liquid separator may be a gravity separation vessel and liquid filled section is located near the bottom of the vessel .
- Optionally recycled gas is injected into the liquid filled section by a series of gas injection nozzles, which inject the recycled gas as an array of finely dispersed gas bubbles into the liquid.
- the series of gas injection nozzles is arranged in a ring shaped gas injection conduit, which is located at a selected distance above the bottom of the gravity separation vessel .
- FIG.l depicts a schematic view of a gas processing and separation assembly in which recycled gas is cooled by the method according to the invention.
- FIG.2 is a top view of the ring-shaped gas injection conduit for injecting finely dispersed gas bubbles into the gas liquid separating vessel .
- FIG.l depicts a gas liquid separator 1 into which a multiphase well effluent mixture G+L is injected via a multiphase well effluent flowline 2, which is connected to one or more subsea wells 3.
- the separator 1 is installed on the seabed 4 and is immersed in the sea or other body of water 5.
- the separator 1 is a gravity separator in which liquid is collected at the bottom of the separating vessel and gas rises to the top of the vessel.
- a liquid stream L is subsequently drained from the bottom of the separator 1 via a liquid flowline 6 in which a liquid pump 7 is arranged.
- a gaseous stream G is discharged from the top of the separator via a gas flowline 8 in which a gas compressor 9 is arranged.
- a gas recycling conduit 10 is arranged between the gas flowline 9 at a location downstream of the compressor 9 and the interior of the separator 1.
- the gas recycling conduit 10 comprises an anti surge valve 11, which is opened if sensors detect the onset of a pressure surge across compressor 9, which may be due to a lack of gas supply at the inlet of the compressor and/or backflow of compressed gas through the compressor 9, which may cause severe mechanical damage to the rotating or static parts of the compressor 9, and/or of a liquid surge within the separator 1. If the valve 11 is opened compressed gas G hot / which is heated by the compressor 9 is recycled into the separator 1.
- the recycled gas In order to cool the recycled gas, which may be recycled several times and is further heated during each recycling step, the recycled gas is injected as a finely dispersed array of gas bubbles 12 into the liquid L at the bottom of the separator 1 via a ring-shaped gas injection conduit 13 in which a series of gas injection nozzles 14 is arranged.
- FIG.2 depicts a top view of the ring-shaped gas injection conduit 13 and gas injection nozzles 14.
- the gas recycle conduit 10 is optionally provided with a heat exchanger 15, which may be relatively small since at least part of the cooling of the recycled gas is accomplished by contacting the small gas bubbles 12 ' with the relatively cold liquid near the bottom of the separator.
- At least part of the liquid L may evaporate as a result of the contact with the hot recycled gas stream G hot -
- the liquid L may comprise gas condensates (C2-C6) and calculations indicate that if a volume of 5 m 3 of gas condensates is heated from 10 to 50 °C then this will correspond to about 10 MW during about 20 seconds, such that the recycled gas stream Gho t is cooled substantially and the heat exchanger 15 may be small or even redundant .
