Post Combustion Capture (PCC) and storage of CO2 with amines is arguably the best available technology for mitigation of rising atmospheric concentrations of CO2. However, a number of serious operational issues threaten its utility. Among these is corrosion of PCC plant in which degradation of amines, particularly in the presence of oxygen, can lead to a range of corrosive products. This study uses electrochemical methods to quantify the corrosiveness of well-known capture agents, such as monoethanolamine (MEA), and compare them with novel solvent blends that have been developed at CSIRO. The amines used in our novel solvents also satisfy the standard PCC criteria of high rates of reaction with CO2, low energy requirements (for regeneration), low volatility and low toxicity. The results of the corrosion tests on carbon steel show that reductions in corrosion rate, compared with those for MEA, are possible with the novel solvents. Under laboratory conditions, the electrochemical data also indicate that the presence of oxygen causes a significant decrease in the corrosion rate in all systems studied. Whether an increase in oxygen concentration can be used in practical PCC applications depends on the long term stability of new amine formulations under these more strongly oxidizing conditions. Longer term testing is required to determine whether novel blends, such as CSIRO-1, possess the required chemical stability in the presence of typical variations in oxygen and CO2 concentration as well as temperature.
