THE CO2 PILOT AT LACQ

Transcription

1 THE CO2 PILOT AT LACQ CO2 CAPTURE, TRANSPORTATION, INJECTION and STORAGE READY FOR START UP Nicolas AIMARD, Claude PREBENDE Total Denis CIEUTAT, Ivan SANCHEZ-MOLINERO, Remi TSIAVA Air Liquide 1 st Oxyfuel Combustion Conference Cottbus, Germany 9 th September 2009

2 What is Total s direct share of GHG emissions? Total operates a daily production of more than 2,5 Mboe/d worldwide Total supplies 2% of heating and automotive fuels used worldwide CO2 emissions to the atmosphere are about 60MtCO2 equivalent per year Our objective is to keep strengthening our portfolio while contributing to energy efficiency and limitation of CO2 emissions 2

3 Why is Total involved in Carbon Capture and Storage (CCS)? Carbon Capture and Storage is considered as a breakthrough technology to be promoted for high CO2 emissions facilities and a promising solution for the O&G industry Extra Heavy Oil and Oil Sands fields development Very acid gas fields development (high CO2 content i.e. >10%) Large LNG facilities Non conventional resources (oil shales) 3

10 AIR LIQUIDE Oxy-burner Principle No external oxygen mixing Advantageous on: flame stability, turndown ratio, difficult fuels. Improved operating safety: dedicated pure oxygen circuit all along distribution system. Additional flexibility to adjust FGR rate. Flue gas recycle Flue gas recycle Oxygen Oxygen Fuel Fuel Synthetic air type AIR LIQUIDE oxy-burner 10

26 Public consultation and dialogue was required Objectives: Share the opportunity of having such project in that area and provide technical information of the Lacq pilot itself Provide a better understanding of CCS technology context, issues and therefore promote the CCS technology deployment Have all questions raised to propose answers at different steps Provide information on short and longer term scientific follow up (dedicated scientific committee appointed with external experts) and monitoring Help identifying project possible contribution to local socio- economic development Demonstrate transparency and provide access to relevant information Total's approach Open dialogue with all stakeholders upstream permitting process Several public meetings open to public in Transparency and access to detailed information, governance Local follow up committee with stakeholders during construction, injection and monitoring phase 26

27 Project information also available on In order to ensure that the consultation process initiated by Total is useful to all concerned, and to guarantee a meaningful dialogue with all stakeholders, the Group undertakes to: Provide full, honest and clearly expressed information about the project (characteristics, impact, surveillance and monitoring system, etc.) so as to facilitate the sharing of knowledge and to foster open discussion with all stakeholders. Execute and report on the project with advice from a number of independent scientific and technical experts. Provide answers to all questions asked by stakeholders or members of the public. Publish minutes of all public discussion meetings as well as a summary of the consultation process, and take these into account in deciding final project details.
