Notes:
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.
