Definitions

  • This invention relates to a method and apparatus 5 processing fluids. s Certain embodiments of the inventi provide a method of gas chilling in unmanned offshore production installations without the use of conventior heat exchanger technology.
  • a method of processing fluids produced from an offshoi wellbore comprising the step of cooling tlr produces fluids by passing them through a cooling cone which extends into the water surrounding the well bore
  • the invention also provides apparatus for process fluids produced from an off shore wellbore, said apparatus comprising a cooling conduit which extends i the water surrounding the wellbore.
  • the cooling conduit is preferably located in the circuit of production fluids immediately after a de- watering facility, where the fluids produced are dehydrated and liquids such as water are removed from production fluids, which can generally comprise gasse ⁇ that stage.
  • the de-watering process typically generat heat due to Joule-Thompson reaction, and this can be dissipated by the cooling conduit.
  • the cooling conduit can optionally extend below t surface of the water towards the sea bed into water at lower temperature than at surface.
  • the cone can have cooling circuits located in the lower regions the conduit at lower temperatures.
  • the conduit is normally part of a sealed circuit that can take the de-watered production fluids and coc them to a temperature at or .below the ambient sea temperature surrounding the pipeline from the platforn so that the cooled fluids leaving the platform stay ir substantially the same phase in the pipeline.
  • Certain embodiments of the invention use a combination of temperature reduction by Joule-Thompsor expansion across an outlet control valve and gas cool- using a cooling conduit submerged in the sea.
  • Fig 1 is a schematic representation of an offshore wellhead platform
  • Fig 2 is a schematic representation of a secc embodiment of a platform.
  • Produced fluids are recovered from a wellbore through a wellhead conduit 1 to a wellhead platform 5 where they are let-down across choke valves A and rout to a bulk liquid/gas separator B.
  • Gross produced liqi is removed at the separator B and under level control is allowed to flow under its own pressure to a dedicat subsea transport pipeline 2 for treatment elsewhere.
  • Offgas from the separator B is removed through conduit to a gas contactor D where hot glycol is fed via condi 4 counter currently down the contactor D to strip out water from the gas by liquid absorption.
  • the water saturated glycol from the contactor bottom is routed 1 to a regeneration system E where the water is boiled c the glycol .
