ABSTRACT The ability to use existing steel infrastructure for carbon capture, transportation and storage (CCTS) networks is critical to their realization. As such, there is a need to understand the corrosion performance of these materials under CCTS operating conditions. While the corrosion of steels in pure, dry carbon dioxide is negligible, the carbon dioxide stream in CCTS may contain significant levels of impurities. Therefore the effect of potential impurities on the corrosion of steels exposed to the carbon dioxide stream must be investigated. In the current work the effects of water, oxygen, ethylene glycol and diethanolamine impurities on the corrosion of carbon and stainless steels under supercritical CO2 conditions were investigated using a high pressure rotating cage. The corrosion of the steels was analyzed by mass loss, scanning electron microscopy and electron dispersive spectroscopy. The stainless steels were found to resist corrosion under all the conditions studied. The presence of oxygen and diethanolamine increased the average corrosion rates of the carbon steels in supercritical CO2 containing water whereas ethylene glycol had no effect. The influence of oxygen on the average corrosion rate of the carbon steels was significantly greater under supercritical conditions than subcritical conditions. Based on these preliminary experiments several refinements to the experimental procedure have been suggested.

ABSTRACT The investigation and use of alternative fuels for automotive applications is increasing as governments, researchers and consumers continue to seek environmentally friendly and sustainable alternatives to petroleum-derived fuels. There is a need to evaluate both the corrosivity of alternative fuels and the corrosion performance of materials intended for service in such environments in order to ensure the continued safety and performance of vehicles and infrastructure. In the current work, nine different steel systems were exposed to pure (B100) and blended (B20) soybean-derived biodiesels under simulated automobile operating conditions. The experimental set-up permitted the comparison of corrosion performance in the vapour and liquid phases. The corrosion performance of the steel systems was analyzed using mass loss and surface inspection methods. The fuel tank systems consisting of uncoated stainless steels outperformed the systems based on coated or pre-painted coated low carbon steels (LCS). The performance of the hot-dipped Pb-Sn LCS control system exceeded the performance of the pre-painted LCS systems. The vapor phase was more corrosive than the liquid phase for pure biodiesel, but no such trend was found for the B20 blend. B100 that had been stored for three years was more corrosive than fresh B100 to the LCS systems but not the stainless steels. Overall the B20 blend was the least corrosive fuel.
