    The low API crude problem

    How to make export quality oil from low API crudes without heating to 120 -140C and without using enormous vessel sizes.

    Some of the challenges:

    Strong Stabilisation WiO Emulsions by Asphalthenic Particles

    High polarity components

    High phase inversion -> high emulsified water content

    Entrapment of Water into Oil Phase

    Heavy crudes can be highly conductive

    Crude treatment The Challenge

    Produced crude oil contains sediment produced water (BS&W), salt and other impurities

    How to remove them?

  • 2008 Aker Solutions part of Aker2-Oct-09 Slide 7

    Crude Treatment

    Water separation from Oil is governed by Stokes Law:

    We manipulate this equation

  • 2008 Aker Solutions part of Aker2-Oct-09 Slide 8

    What can we manipulate?

    Aker Solutions have proprietary and patented components to coalesce/increase the water size d using:

    Mechanical impingement

    Turbulent & cyclonic flow

    Electrostatics

  • 2008 Aker Solutions part of Aker2-Oct-09 Slide 9

    Mechanical coalescing Patented matrix packing

    1 triangular sections with a 45downward slope.

    How it Works

    Water droplets hit the corrugated plates, collide with each other & grow

    Larger droplets slide down the plate channels, flow to the bottom water phase of the vessel.

    Advantages

    Self cleaning action that prevents plugging and is self draining

    Enhances coalescing

    Increases buoyancy drive between the oil and water

  • 2008 Aker Solutions part of Aker2-Oct-09 Slide 10

    Turbulent coalescing Patented Adjustable Flow Distribution baffles

    Horizontal flow distribution

    Ensures even flow for heavy oil thus even temperature profile in the separator

    Turn down to 25%

    Promotes coalescing via impingement & turbulence

  • 2008 Aker Solutions part of Aker2-Oct-09 Slide 11

    Cyclonic Coalescing Patented Compact Cyclonic Inlet (CCI) device Anti Foaming Cyclonic Inlet Device

    Promotes separation & coalescing via centrifugal forces and impingement on the cyclone wall

  • 2008 Aker Solutions part of Aker2-Oct-09 Slide 17

    Compact Electrostatic Coalescer (CEC)Compact Offshore High Performance Technology

    Proprietary, patented solution for improvement of separation of water from oil Compact and standardized design

    Large operating window, high performance

    Robust and highly offshore suitable

    Debottlenecking for existing production facilities:Enhances performance of existing downstream separation equipment

    Electrostatic field and turbulence make droplets coalesce: Electrostatic field

    Water droplets become polarized (e.g. dipoles)

    Emulsifying films are distorted and weaken => contributing to emulsion breaking

    Droplets vibrate collisions

    Mild Turbulence

    Random droplet collisions

    Increase droplet to droplet contact => higher coalescing efficiency

  • 2008 Aker Solutions part of Aker2-Oct-09 Slide 18

    CEC Technology

    Configuration Number of concentric electrodes depending

    on liquid production rate Intense AC electrostatic field, voltage

    modulation Energized electrodes are coated

    Unique dynamic power control Rapid modulation and better control

    Larger water droplets rapidly settling in separator, shorter residence time, hence smaller separator vessel

    Comparing CEC to traditional equipment: Typical conventional up-flow EC:

    20 350 BPD/ft2 CEC + Separator:

    400 BPD/ft2 Reduction in size, footprint, weight Typical CEC size: 5.5 m height, OD

    Design Analysis

    Traditional FWKO Design Separation of free (non-emulsified) water from crude oil

    The Problem: Typical 16 API Heavy oil holds more than 30% water as

    emulsion

    Typical Dilbit blend of 1/3 Diluent and 2/3 SAGD Bitumen blended to 16 API would typically hold ~22% water

    Emulsions are not broken in FWKOs unless heat is applied

    and/or coalescence inducing internals are utilized

    and demulsifying chemicals are used.

    Conclusions: SAGD Dilbit FWKOs with better than ~20% outlet performance

    are actually high temperature coalescing separators
