After a comprehensive evaluation TCM selected two processes, a chilled ammonia process from Alstom and an amine process from Aker Clean Carbon (ACC).
Both technologies are post-combustion capture and utilise a solvent for absorbing the CO2 from the flue gas. Both are also designed to capture 85% of the CO2 contained in the flue gas from the refinery cracker and the combined heat and power plant.
The size of the facility, the flexibility and features implemented in the specifications and design opens the door for extensive test options. These tests will generate a significant amount of results. The size of TCM means from the results we can extrapolate relevant information for eventual full scale implementation around the world.
Post-combustion capture is a technology group most applicable to retrofit existing plants. It additionally is a technology suitable for testing with alternative emission sources, such as that from the Mongstad refinery cracker unit.
Technology that matters.
TCM’s partners have made a clear commitment to technology improvement and invested 5 billion Norwegian kroner for the construction and development of the technology centre. Designed to capture about 100,000 tonnes per year of CO2, the project will be the largest demonstration of CO2 capture technologies to date.
To date no full scale CO2 capture facility for flue gas has been built, meaning cost estimates are highly uncertain. Up to eighty percent of the costs of CCS technology are related to the CO2 capture facility. Therefore in order for these promising technologies to make a difference globally, we must refine the technology processes and bring costs down. At TCM we will test CO2 capture technology to take its development one step further.
Through testing, verification and demonstration of technologies, TCM aims to reduce both the operating and capital expenditures, and to improve performance and reliability. Increasing knowledge on the chosen capture technologies will allow for a reduction in technical and financial risk uncertainty, and provide qualified technologies capable of wide scale international deployment.
A distinctive opportunity at Mongstad.
Located at the Mongstad oil refinery northeast of Bergen, Norway, the technology centre will have access to flue gas from the natural gas combined heat and power plant and the flue gas from the refinery cracker. The CO2 contents are about 3.5% and 13%, respectively, which provides TCM with a unique opportunity to be able to investigate capture technologies relevant for coal and gas fuel power plants, as well as other industrial applications.
