Recently, experiments have been performed to determine the electrochemistry of mild steel at high pressures of carbon dioxide (CO2) and in the presence of acetic acid (HAc). An electrochemical model which has been validated with data collected in glass cells will be compared to the new data which has been gathered in a high pressure flow loop Furthermore, the de Waard corrosion model has been modified to account for the presence of acetic acid and the predicted corrosion rated from the de Waard model will also be compared to the experimental corrosion rate data found by using linear polarization resistance (LPR) and weight loss measurements.
