AGENDA

• Produced water
• The CTour technology
• History
• Status 2006

PRODUCED WATER

• During production of oil gas, water is
  separated and emitted to sea (main method)
• Mature fields, watercut of 50-80
• Increasing global environmental problem
• Water treatment, bottleneck in the production
• New regulations in the Northsea (OSPAR )
• Zero harmfull emission to sea in the Norwegian
  sector from 2006
• Increasing global interest for treatment
  technologies for produced water
• OSPAR (Convention for the Protection of the
  Marine Environment of the North-East Atlantic)

PRODUCED WATER - CTOUR

• Concidered the best available technology for
  cleaning large amounts of produced water to very
  low hydrocarbon concentrations

Unique
Simultaneous Removal of Dispersed and Dissolved
Hydrocarbons
6
TECHNOLGY THE PROCESS

• Reduces OiW discharge to 1-5 ppm (feed OiW 200
  -1000 ppm)
• Removes the dissolved fraction of the following
  aromatic hydrocarbon contaminants (up to 95 )
• BTEX (Benzene, Toluene, Ethyl benzene, Xylene)
• SVOC (Soluble Volatile Oil Components)
• - naphtalenes
• - PAHs (poly aromatic hydrocarbons)
• - alkyl phenols

1.stage separator
Injection of condensate
Reject stream back to main process
CTour inj. mixing unit
Produced water 200-1000ppm
Hydrocyclone
- hydrocarbon contaminants are extracted by
condensate, oil and condensate droplets
coalesces
- the condensate is separated in the hydrocyclone
and routed back to main process
Treated water 1-5 ppm to sea
15-40 ppm to sea
