Abstract
The effect of temperature and H2S concentration on amine corrosion of API 5L X52 carbon steel in a CO2saturated 25 wt diethanolamine solution was investigated via electrochemical techniques It was found that increase in temperature from 25 to 80 °C resulted in severe increase in corrosion rate from 088 to 1624 mpy due to increase in degradation rate of amine Also it was concluded that increase in H2S concentration led to increase in corrosion rate because of formation of more heat stable amine salts The effect of temperature on corrosion rate was more significant than acid gas loading
