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 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

Compact Electrostatic CoalescerCEC
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
