| Abstract | The development of hydrocarbon gas fields which contain very high CO2 contents (up to 80 mol%) using carbon steel seems a difficult proposal and calls for the use of expensive corrosion resistant alloys. This would have the potential to render project development costs untenable. Unlike transportation and sequestration of supercritical CO2, where the amount of water is normally very small or negligible, gas field development has to consider the presence of formation water. This water can contain a high concentration of corrosive species, generated by large amounts of dissolved CO2. The magnitude of corrosion and the effect of flow on corrosion in such environments are unknown and a better understanding is required. Flow has the possible effects of challenging the protectiveness of any corrosion product films that may form and will increase the mass transfer rates of corrosive species to the pipe wall, both leading to an increase in corrosion rate. In the present study, a High Pressure and High Temperature (HPHT) Thin Channel Flow Cell (TCFC) was employed to study the flow sensitivity of CO2 corrosion of carbon steel, at subcritical and supercritical CO2 partial pressures. The corrosion rate measured in the TCFC was related with the one obtained in a HPHT rotating cylinder electrode (RCE) autoclave tests. This was done to ascertain the independence of the measured corrosion rates from the specific flow geometry. |
