The overall decomposition of the amines is a combination of thermal degradation from the elevated temperatures in especially the stripper unit and oxidative degradation from ionic and radical reactions with the oxygen in the flue gas . The proposed replacement of the thermal stripping unit with the biological process of biomethanation in this concept could therefore potentially lead to an extended lifetime of the amines. However, the amines would also be subject to a currently undetermined microbial degradation. The MDEA amine has in a various studies been reported to be an inaccessible and recalcitrant carbon source for an anaerobic consortium of microbes, which suggest a low microbial degradation of MDEA . However, a continuous metabolic conversion of CO2 and H2 using a mixed culture as here, could lead to the co-production of acetate. The presence of acetate could reduce the capacity of the system by creating heat stable salts with the amines . Hence, further studies should study biological degradation rates and the lifetime of the specific solvents to evaluate the full potential of this biomediated carbon capture system.
