Definitions

  • the present invention relates to a subsea multiphase fluid separation system, i n particular to a gas-liquid and liquid-liquid gravity separator for subsea applications.
  • the subsea separator according to the invention is particularly useful for separating gas, oil and water phases in multiphase flow streams at oil fields located subsea.
  • Multiphase fluids separators based on gravity comprise preferably cylindrical vessels horizontally arranged, for separation of fluids such as oil, water and gas suitable in a number of context in process plants. Specific improvements to provide compact and efficient separation vessels which can be used in subsea fluid processing have been disclosed.
  • U.S. Pat. Appl. No. 2010/0326922 discloses a cylindrical separator which includes in the separator a multifunctional surface super-hydrophobic with respect to water in order to provide a compact and efficient separation vessel.
  • spherical separators particularly suited for use in separating natural gas from high pressure, high velocity production streams. Both the separators comprise an interior surface defining a spherical interior space.
  • a baffle is provided in the housing for obstructing direct flow from the liquid gas inlet to the gas outlet.
  • a nozzle deflector and an inlet deflector are provided i nside the separation vessel in order to spread and to encourage the flow of a stream introduced into vessel to turn downward and radially outward toward the walls of vessel.
  • Multiphase fluids separators based on a cyclone separator generally consists of a tube in which a central flow body is arranged.
  • the relatively heavy fraction of the mixture is flung outward, while the relatively light fraction of the mixture is displaced in a zone along the flow body. Because the light and heavy fractions are displaced in separate zones, a separation of the mixture can be effected by arranging outlet provisions at a suitable location, and the separated light and heavy fractions can be discharged separately.
  • U.S. Pat. No. 2,588,863 discloses a first attempt of de-sanding spherical centrifugal separation.
  • the shell of the separator has a top fluid discharge nipple and a bottom sediment outlet. It is not explicitly highlighted a possible subsea application.
  • the spherical shell is provided with a co-center, inner vertical axis cylinder purposely angled to be highly favorable in making an additional through-off of suspended particles in the flowing liquid (such as water). Liquid flowing rapidly in the inlet tube onto a ramp will at once begin to rotate in a helical path.
  • VASPS vertical annular separation and pumping system
  • a VASPS unit is frequently used as part of a subsea multiphase boosting system and artificial lifting method to increase reservoir production rates.
  • a VASPS is a two-phase (gas-liquid) separation and pumping system which may be installed subsea.
  • a further improvement of the VASPS unit described in U.S. Pat. Appl. No. 20090211763 which discloses a self-contained unit which includes an outer pressure housing, an inner helix separator assembly, a gas discharge annulus, a liquid discharge tube.
  • Cyclone separators are used in a large number of situations.
  • Inlet cyclones are, for instance, applied in gravity separation vessels. Inlet cyclones ensure that the incoming mixture undergoes a determined pretreatment before a further separation takes place.
  • the inlet cyclone can be connected for this purpose to the inlet of the gravity separation vessel and provided with an outlet for the heavy fraction and an outlet for the light fraction, wherein both outlets debouch in the interior of the gravity separation vessel for further separation of the mixture. Examples of an inlet cyclone are described in the European patent application EP 1 187 667 A2, and in U.S. Patent No. 7,833,298.
  • cyclone separator Another type of cyclone separator is the so-called in-line separator in which the incoming mixture and at least a part of the outgoing mixture flows through a pipeline, wherein the separator is essentially aligned with the pipeline.
  • In-line cyclone separators can be subdivided into two different types.
  • a first type also known as a " degas ser”
  • the separator separates gas from liquid.
  • the degasser is used, in the case of the gas/liquid mixture, when the continuous phase is liquid.
  • An example of a degasser is known from WO 01/00296.
  • the liquid continuous flow is set into rotation by a number of guide blades causing swirling. Because of the difference in density between the gas and liquid and the initiated centrifugal field, the gas is urged to the middle of the separator, thus producing a stable core of gas. Removal of the gas core is brought about by means of a gas discharge pipe arranged in the middle of the cyclone and provided with outlet openings. Because of the geometry of the separator, removal of the gas via the outlet openings takes place in radial direction.
  • a second type of in-line cyclone separator is a separator, also referred to as a "deliquidizer", in which a gas continuous feed is set into rotation by a number of guide blades causing swirling.
  • the deliquidizer in this case separates the liquid from the gas.
  • the liquid is urged in the direction of the pipe wall, which results in a stable liquid film (layer) which is displaced in the direction of the gas outlet.
  • the gas outlet is a cylindrical open pipe which is fixed in the flow space of the separator.
  • the gas is discharged in longitudinal direction.
  • the main task of the present invention is to provide a subsea multiphase fluid separation system which overcomes or minimizes the drawbacks of known systems.
  • an object of the present invention is to provide a subsea multiphase fluid separation system that would avoid lifting large volumes of water to the surface for processing and disposal.
  • Another object of the present invention is to provide a subsea multiphase fluid separation system capable to guarantee successful operation i n a wide range of 3-phase flow regimes also in presence of a solid phase.
  • Still another object of the present invention is to provide a subsea multiphase fluid separation system, that will not require or will minimize the equipment for post- treatment of the outgoing fluid stream(s).
  • a further object of the present invention is to provide a subsea multiphase fluid separation system, with increased reliability and limited maintenance,.
