Abstract: (264 Views)
One of the main problems in the oil and gas industry is CO2 corrosion which is known as sweet corrosion. The
use of corrosion inhibitors is one of the most effective methods for corrosion control in the oil and gas industry.
In this paper, the mechanism and effect of concentration of an imidazoline base derivative on CO2 corrosion of
carbon steel was investigated. For this purpose, the corrosion behavior of a plain carbon steel in a NACE standard
solution at ambient temperature was studied. The open circuit potential (OCP) and potentiodynamic polarization
measurements in presence of different concentrations of imidazoline inhibitor were conducted to determine the
corrosion rate of samples. . The results showed that the imidazoline base inhibitor reduced the kinetics of anodic
reactions by adsorption on the metal surface and blocking the active corrosion sites . Also, it was observed that
15 ppm of imidazoline inhibitor provided the optimum inhibition efficiency of 89.87%
