FIG.1 is a schematic view of a subsea processing system according to the invention. Detailed Description of the Invention:
A liquid level transmitter measures the liquid level in the separation vessel and transmits the level signal to a controller, which adjusts the pump speed setpoint in a cascade arrangement to maintain the liquid level at a predetermined setpoint. The level controller is tuned to provide extremely fast action for handling level disturbances caused by changes in the liquid feed rate, such that the pump speed setpoint is almost instantly adjusted to respond to changes in liquid level. However the level controller also provides stable pump speed when the liquid feed rate is stable.
The fast acting variable speed drive receives its speed setpoint from the level controller and increases or decreases the pump speed within 2 seconds, being limited only by the physical capabilities of the particular variable speed drive. This fast acting level controller enables the use of compact separation systems as the liquid interface level can now be maintained within a small boundary.
It is also preferred that the pump is a gas tolerant or multiphase pump, to ensure occasional separator drainage or gas surge can be tolerated when severe liquid feed disturbances occur which may require a faster pump speed response than is physically possible with the variable speed drive. It is furthermore preferred that:
the flowline for transferring the gas enriched fluid fraction is connected at or near the top of the separation vessel and the flowline for transferring the liquid enriched fluid fraction is connected at or near the bottom of the gravity separation vessel, that the flowline for transferring the gas enriched fluid fraction is equipped with a liquid overflow valve, which is closed if liquid enters the valve, the separation vessel and liquid valve overflow valve are arranged in a separator module which is rethevably mounted on a pump station base at the seabed and - the pump and the electric pump motor are mounted in a pump module, which is rethevably mounted on the pump station base. Furthermore, an inlet of a fluid recirculation conduit may be connected to the liquid enriched fluid transportation conduit at a location downstream of the pump and an outlet of the fluid recirculation conduit is connected to the multiphase well effluent transportation conduit, which conduit is equipped with a valve, which is opened during start up of the pump and which is subsequently closed.
In accordance with the invention there is furthermore provided a system for subsea processing multiphase well effluents comprising natural gas and liquid from an underwater hydrocarbon containing formation, the system comprising:
- a fluid separation vessel which is connected to a downstream end of a multiphase well effluent transportation conduit;
- a liquid level transmitter assembly for monitoring the gas liquid interface in the fluid separation vessel;
- a liquid level controller which receives the signal from the level transmitter and generates a pump speed setpoint for controlling the liquid level to a predetermined setpoint;
- a liquid enriched fluid transportation flowline connected at or near the bottom of the fluid separation vessel and a gas enriched fluid transportation flowline connected at or near a top of the fluid separation vessel;
- a pump connected to an electric motor;
- a fast acting variable speed drive system, which is coupled to the liquid level controller which control the pump and motor speed as fast as physically possible, within 2 seconds, to achieve the pump speed setpoint from the level controller. These and other features, embodiments and advantages of the method and system according to the invention are described in the accompanying claims, abstract and the following detailed description of a preferred embodiment disclosed in the accompanying drawing in which reference numerals are used which refer to corresponding reference numerals that are shown in the drawings.
Figure 1 :
FIG.1 shows a subsea processing system 1 according to the invention comprising a separation module 2 and a pump module 3 that are rethevably mounted on a base 4, which is mounted on the seabed 5. The separation module 2 comprises a gas-liquid separation vessel 6, which is connected to a multiphase well effluent flowline 7, which is connected via a manifold 8 to a pair of subsea gas wells 9 and 10 which produce a multiphase flow mixture of natural gas, water, condensates and optionally crude oil from an underwater gas reservoir (not shown). The gas- liquid separation vessel 6 is provided with an upper outlet 1 1 for discharging a gas enriched fluid fraction into a gas transportation conduit 12 and with a lower outlet 13 for discharging a liquid enriched fluid fraction into a liquid transportation conduit 14. The gas and liquid transportation conduits 12 and 14 comprise vertical riser sections 12A, 14A, which are suspended below a floating platform 15, which floats at the water surface 16.
In order to enhance the liquid production and reduce the backpressure of the hydrostatic liquid column in the liquid filled riser section 14A on the separation vessel 6 the pump module 3 comprises a gas tolerant liquid pump 17, which is driven by an electric motor 18 that is powered via an electrical cable 19 by an electric power source 20 at the platform 15.
The electric motor 18 is equipped with a fast acting variable speed drive system, which is coupled, as indicated by dashed line 24, to an assembly of two liquid level transmitters 21 and 22 and a level controller
which monitor the liquid level 23 in the separation vessel 6. The level controller provides the speed setpoint to the fast acting variable speed drive system. The level controller will increase the speed of the motor and pump assembly 17,18 within 1 to 2 seconds if the liquid level increases above its setpoint 21 and the level controller will decrease the speed of the motor and pump assembly 17,18 within 1 to 2 seconds if the liquid level 23 drops below the predetermined liquid level controller setpoint 21.
In order to inhibit liquid to flow into the gas transportation conduit 12 in case of a liquid surge a liquid overflow valve 25 is arranged in the gas transportation conduit 12 in the vicinity of the upper gas outlet 1 1 , which valve automatically closes itself if a liquid surge enters the valve.
During start up of the pump 17 at least a fraction of the liquid discharged from the lower liquid outlet 13 is circulated back to the multiphase well effluent flowline 7 through a liquid recycling conduit 26, which is equipped with a valve 27, which is opened during the pump start up phase and which is subsequently gradually closed. The valve 27 may comprise a conventional subsea choke and an on-off valve, which does not need to be fast acting as failure to control the recycle flow rate will not have a detrimental effect on the multiphase pump 17. Thus an advantage of the subsea processing system according to the invention is that the valves 25 and 27 may be simple on off valves, which do not require a complex dynamic control of the valve openings and that the electric motor 18 is the only subsea component which is dynamically controlled by a fast acting variable speed drive system which receives its speed setpoint from a level controller.
The modular construction of the system 1 allows replacement, inspection and/or repair of the retrievable pump and separator modules 3 and 2 by disconnecting the stab-in pipe joints 30 and the subsea power cable connector 31 and then lifting the pump and/or separator module 3,2 to a vessel at the water surface 16 for replacement inspection and/or repair.
It will be understood that the processing system 1 according to the invention may be installed at the bottom 5 of an ocean, sea, lake and/or river and that the term "subsea" as used in this specification and the
accompanying claims should be interpreted extensively so that it embraces all these options.
