CO2 wet gas corrosion rates at the top and bottom of a high pressure 10-cm diameter system have been measured under different pressures up to 1.82MPa at a temperature of 40°C. The flow patterns at test conditions are determined at gas velocities up to 1 lm/s and liquid velocities up to 0.2m/s. The liquid was de-ionized water and carbon dioxide was used as the gas phase. The flow patterns at test conditions are annular flow or near the stratified-annular flow transition zone. The corrosion rate becomes stable after 3 hours. It was found that the
corrosion rate increases with the increase in gas velocity, liquid velocity, and CO2 partial pressure.
