Carbon Clean Solutions Limited (CCSL) has announced breakthrough test results after a successful pilot campaign at the world’s largest and most advanced facility for testing and improving carbon dioxide (CO2) capture.
The trial, carried out at Technology Centre Mongstad (TCM), involved a drop-in solvent test using CCSL’s patented ‘APBS,’ which involves capturing CO2 using a re-generable solvent combined with a unique heat coupling method.
The flue gas discharged from the chimney is extracted from the existing stack and fed to the carbon capture storage (CCS) unit through a flue gas duct, and after cleaning the gas, it is passed through an absorber for capturing CO2. The CO2 recovered can then be used as a raw material for downstream industries.
During the test, which was designed to measure environmental emissions, corrosion and energy efficiency, CCSL successfully captured more than 25,000 tonnes of CO2 with plant availability levels reaching the maximum 100%.
Additional corrosion testing also revealed that it would be possible to construct up to 50% of a plant using carbon steel rather than stainless steel, with the use of APBS. As the traditional solvents required in stainless steel cost around four times the amount of those used in carbon steel, CCSL has reduced the potential capex for commercial scale plants by 25%.
Furthermore, an independent study carried out at the University of Kentucky proved a 50% reduction in energy consumption when using APBS compared to traditional solvents, proving that it could be possible to reduce the overall cost of carbon capture by 50%, on a commercial scale.
Aniruddha Sharma, CEO at the India-based corporation, enthused, “This pilot demonstrates a breakthrough in carbon capture technology, in terms of our ability to dramatically reduce corrosion, energy demand and solvent emissions. This translates to cost savings, both operational and upfront, which we believe will make carbon capture storage and reuse economically viable in the near future.”
The carbon capture technology specialists undertook the pilot test from November 2015 to March 2016 at the Technology Centre Mongstad (TCM) in Norway.
TCM is a joint venture set up by the Norwegian state (75.12%), Statoil (20%), Shell (2.44%) and Sasol (2.44%), and is the world’s largest facility for testing and improving CO2 capture. It aims to increase knowledge on carbon capture technologies, to reduce technical and financial risk and accelerate the development of qualified technologies capable of wide scale international deployment.
