Project Outline

My PhD project focuses on developing a model to understand the corrosion of carbon steels, in environments containing CO2, by using principles of corrosion, thermodynamics and kinetic factors to model the corrosion of carbon steel in CO2 containing solutions. This model will allow us to interpret commonly used test environments in a more technically robust manner, thus providing more meaningful information.

My research will investigate the effect of gas pressure and temperature on the solution’s pH, the correlation of acid gas partial pressure in HPHT conditions to its fugacity, the effect of salinity on the solubility of different gases (such as CO2, H2S and O2), the effect of Fe saturation on the pH of test solution and the effect of solution chemistry on the corrosion rate of carbon steel.

The output of this project would be a be-spoke model with tailored features based on the chemistry of corrosion process.
