Transcript of Overview of TCM Mongstad
TCM is the world’s largest facility for testing and improving CO2 capture.
Knowledge gained will prepare the ground for CO2 capture initiatives to combat climate change world wide.
TCM – Highlights
2006
2009
2012
2005 Government policy: No carbon based power generationin Norway without CCS
State and Statoil agreed 2-staged approach:1: Demonstrate and develop capture technologies (TCM)2: Build large scale (1 mTons CO2/year) capture plant
Investment decision taken for TCM: = USD1BillionPartnership established (TCM DA)
Five year initial test period started
Power plant
Amine plant
Chilled ammonia plant
Admin complex
Substation
Utility systems
Area for future technologies
Sea water inlet
CO2 vent
Catalytic cracker
▪ Reduce costs (Cost/kWh)▪ Mitigate risks
▪ Take active part in shaping the technology landscape
▪ Be a centre in global network ▪ Exploit synergy with other players
and institutions
Drive technology development
Position TCM at centre of a global knowledge network
Establish CCS as cost efficient climate solution with acceptable risk

Discharge permit process – initial risks
• Large uncertainties regarding the effect of amine emissions as well as amine degradation products to people and the environment
• Studies were launched to close this knowledge gap• Open communication established with local communities as
well as the authorities – gained trust
Discharge permit process - highlights• Application for discharge permit was sent to the Climate and
Pollution Agency (Klif) 3.9.2010• Official hearing process started 5.10.2010• Close dialogue and contact with Klif in the process• New knowledge obtained (from various studies) and sent to
Klif during the handling period• NIPH set guidelines for emissions• Final discharge permit given 16.11.2011

Degradation pattern and rates
Dispersion modeling - transformation rates and deposition values
Acceptable threshold values – water and air
Final fate of components
Discharge permit – Summary • Final permit received 16.11.2011• Air: Regulated on amines, ammonia, aldehydes, nitrosamines and nitramines. Air
concentrations expected to be lower by ratio 3 – 5 compared to guidelines • Water: Regulated on energy in cooling water effluent. Water concentration
expected to be lower by ratio 16 – 22 compared to guidelines• Extensive regulation on follow up activities, environmental monitoring and
measurement program. In addition extensive documentation must be sent to Klif two months in advance before TCM is able to take in and use new solvents.
