- It is a great pleasure to be a part of this unique plant which is of international importance, to be involved in both the building of a carbon capture plant, in addition to operating our own technology in test campaigns over 14 months, says Liv Monica Stubholt, CEO of Aker Clean Carbon.
With one of the two technology plants complete, TCM has now passed an important milestone, and is one step closer to start the groundbreaking test programmes at the gigantic test facility located next to a refinery near Bergen on the west-coast of Norway. The aim is that knowledge gained here will prepare the ground for CO2 capture initiatives to combat climate change.
Large and flexible
- 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, says Tore Amundsen, Managing Director of TCM.
TCM will be in the unique position of having 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 enables TCM to investigate capture technologies relevant for coal and gas fuel power plants, as well as other industrial applications.
One of the technologies at TCM is a post-combustion capture technique using amines with Aker Clean Carbon as the technology provider. In amine technology, CO2 is captured by an amine solvent, a liquid comprising of water and amines, which is being used to absorb the CO2 from the flue gas.
Amine technology has been used for decades in other applications and is therefore considered to have a moderate technical risk. However, TCM will evaluate opportunities for improvements in process design, construction methods and operations with the purpose to qualify the technology for use in large scale post-combustion plants. Aker Clean Carbon has included several technology improvements in the plant such as; improved amines, energy saver and emission control. The flexible absorber is 62 metres high and is constructed in concrete with a liner.
More about how the technology work
TCM is a joint venture between the Norwegian state, Statoil, Shell and Sasol. TCM will not only be one of the first large scale demonstration plants, but also the first of its kind to test two different types of capture technologies from two different sources of CO2, side-by-side. While the amine plant will start operating at the end of this year, the chilled ammonia plant delivered by Alstom will start operating next year. There is also space provided for a possible third technology at TCM.
