Experimental and Modelling Study of Amine Degradation in the Post-Combustion CO2 Capture Process

Post-combustion capture of CO2 from fossil fuel derived flue gas using amines is one of the leading Carbon Capture and Storage (CCS) technologies. The amines used for post-combustion capture can degrade in the presence of oxygen and other flue gas compounds and an understanding of the nature of amine degradation is important for accelerating deployment of the technology. This project will conduct laboratory and pilot-scale experimental investigations into amine degradation in order to characterise the liquid phase reaction rates using GC-MS and HPLC and also simultaneously characterise the rate of evolution of gas-phase species using FTIR. The experimental results will be used to develop liquid-gas phase numerical chemical kinetic models which can be incorporated into process system simulation models of the post-combustion capture process such as Aspen.
