The carbon dioxide corrosion electrochemistry of mild steel has been studied in the presence of high CO2 partial pressures and acetic acid (HAc). Potentiodynamic sweeps, linear polarization resistance (LPR) and weight loss (WL) experiments have been conducted to investigate the effects of flow velocity, CO2 partial pressure, and acetic acid concentration on the corrosion rate of mild steel. Electrochemical impedance spectroscopy measurements have also been conducted to help elucidate the corrosion mechanisms under the test conditions.
