Definitions

  • the present invention relates, in general, to separation systems and, in particular to gas/liquid mixture separation, for example including a secondary separator for an arrangement for separating a multiple phase mixture into separate vapor and liquid phases utilizing pairs of centrifugal cyclone separators.
  • the separation arrangement utilizes one or more curved-arm, centrifugal force, primary separators) and one or more secondary centrifugal cyclone separator(s).
  • the primary separator is similar to the separator described in U.S. Patent No. 4,648,890.
  • the secondary separator is similar to the separator described in U.S. Patent No. 3,324,634.
  • the combination of a centrifugal-type primary and secondary separator provides a compact and highly efficient separator arrangement.
  • the separator arrangement can be used in multiple pairs (two or more primary and secondary separators) or as a single-module pair. The multiple pairs are typically used for topside applications while a single-modular pair will satisfy most sub-sea applications.
  • An aim of at least an embodiment of the present invention is to modify the inlet vanes of the secondary separator in a gas/liquid separator containing both primary and secondary separator stages, which improves fluid flow past the vanes and overall separator efficiency.
  • the vanes are curved and may be cast, thus permitting the separator to be manufactured using dies rather than welding the vanes in place as was done in the prior art.
  • the present invention provides an arrangement for separating a gas and liquid mixture, the arrangement having a vessel with an inlet for entry of the gas and liquid mixture and an outlet for exit of a separated gas, at least one primary centrifugal separator in the vessel for centrifugally separating the gas from the mixture; and at least one secondary centrifugal separator in the vessel for further centrifugally separating the gas from the mixture; characterised by: the secondary separator having means defining an enclosure with an annular gas/liquid separator space having an outer circumferential inlet, and an inner circular outlet; and a plurality of fluid directing vanes circumference spaced around the separator space, each vane being curved in the same direction of curvature from the inlet to the outlet.
  • a primary separator 30 shown in Fig. 1 comprises a riser tube 32, four sets of multilayered curved arms 34, and an outer can or return cylinder 36 surrounding riser 32 and arms 34.
  • the gas/liquid mixture 12 enters at the bottom of the primary riser 32 and flows up and through the curved arms 34 where the majority of the centrifugal separation occurs.
  • a film of liquid 26 develops on the inner wall of the return cylinder 36 and cascades down to the main inventory of liquid (not shown) below the separator 30.
  • the return cylinder 36 extends above the top of the curved arms 34 where there are a number of half-inch (12.5 mm) diameter perforations 38 and a retaining lip 40 at the open top of separator 30 which are used to improve the liquid removal capabilities of the separator 30 at high gas and liquid flows especially where slug conditions can exist.
  • the wet gas 12 exits the top of the primary separator(s) 30 in a substantially open interstage region 44 which is used to more evenly distribute the wet gas prior to its entering the secondary cyclone(s) 50.
  • the distance between the multi-layered curved arms 34 and the top of the primary cyclone separator 30 is indicated at reference numeral 48 and preferably ranges from approximately 15 to approximately 18 inches (380 mm to 460 mm).
  • the secondary cyclone 50 also operates on the principle of centrifugal separation.
  • the wet gas 28 enters the cyclone 50 through tangential inlet vanes 54 at the bottom of the cyclone 50 which imparts a centrifugal motion on the fluid. Any liquid remaining in the gas is then forced to the inner wall of the cyclone 50 where it is separated by skimmer slots and spills into a secondary compartment (not shown).
  • Bypass holes are placed in a top plate of the secondary compartment to allow a certain amount of gas flow 29 to bypass through the secondary skimmer slots to enhance the skimming action.
  • the separated liquid then drains via a drain tube (not shown) back into and becomes a part of the main pressure vessel's liquid inventory.
  • the drain tube isolates the returning separated liquid from the upflowing main gas flow and avoids the re-entrainment of separated liquid by the incoming gas/liquid mixtures 12. Dry gas exits at 20 through outlet 57.
  • the secondary cyclone 50 has an inherent advantage over scrubber or mesh type dryers. Both the scrubber and mesh dryers are limited in flow capacity by the droplet entrainment threshold beyond which liquid droplets are entrained with the vapor and are carried downstream.
  • the secondary cyclone 50 can efficiently operate at vapor fluxes typically two to three times higher than the entrainment threshold.
  • the enclosure 60 of the secondary separator defines a separator space with an outer circumferential inlet 64 for receiving gases latent with liquid and an inner axially directed circular outlet 66 for discharging liquid free gases.
  • the plurality of vanes 54 which each extend at an angle from the inlet to the outlet, have conventionally been made of sheet metal and have been welded in place between the upper and lower plates of the enclosure 60.
  • the vanes 56 are curved and arc from the inlet 64 to the outlet 66.
  • Each vane 56 has a thickness and is cast.
  • the shape may also be wing- or foil-shaped to improve fluid flow of fluid entering the enclosure 60.
  • a die can be used to extrude or cast the vanes, for example, of aluminum or other metal.
