Critical Knowledge for CO2-Intensive Industries to Implement Amine-Based Carbon Capture

Abstract

This paper has been written to provide some decarbonization guidelines and recommendations for different CO2 intensive industrial applications, such as, Cement, Oil Refineries, Waste to Energy, Steel, H2 Production, Aluminum and Pulp & Paper. Relevant information has been provided for any potential project targeting a significant reduction in CO2 emissions. The importance of flue gas characterization has been indicated, including which typical components in the flue gas should be measured, which are important for properly planning and designing a CO2 capture project. Additionally, based on Technology Centre Mongstad (TCM) experience with both clean flue gas (CCGT) and more contaminated flue gas (RFCC), recommendations are given for the importance of good solvent hygiene and maintaining low amine emissions to the stack and surrounding environment. It is expected that each of the industrial applications described will lie somewhere between the CCGT and RFCC in terms of flue gas cleanliness. It has also been demonstrated that material integrity of a CO2 capture plant can be compromised if solvent hygiene is not maintained. Also, how the material integrity and selection can have considerable impact on CO2 capture plant cost and reliability of operation
