Inhibition of CO2 corrosion of carbon steel by rosin amide
Abstract
The inhibition of sweet gas corrosion of carbon steel in high pressure CO2 saturated brine by rosin amine has been studied by weight‐loss, electrochemical polarisation and electrochemical impedance spectrum measurements. The results obtained revealed that rosin amine compound is a good inhibitor. The inhibition efficiency increased with the increase of inhibitor concentration. Rosin amine acts mainly as a adsorptive mixed‐type inhibitor. The adsorption of the inhibitor on the metal surface in high pressure CO2 saturated brine obey Langmuir isotherm. The adsorption mechanism of inhibitor was both electrostatic‐adsorption and chemisorption.
