    A New Type of CO2 Corrosion Inhibitor

      Graphical Abstract
      • Abstract
    • A new type of CO2 corrosion inhibitor HQHP was synthesized by Mannich reaction.The performance evaluation showed that the appropriate amount of the corrosion inhibitor was 400 mg/L.At high temperatures,the inhibition efficiency in liquid decreased with the increase of temperature,but the the inhibition efficiency in gas decreased firstly and then tended to be stalde.When the temperature rose from 70 ℃ to 80 ℃,the inhibition efficiency increased slightly.The corrosion inhibitor had good water-soluble and non-emulsifying tendency.
