Corrosion inhibition efficiency of the Myrrh Gum on API 5CTP110 tubing in hydrochloric acid

The corrosion inhibition properties of Myrrh Gum (MG) on API 5CT P110 tubing in 0.5 M HCl solution were investigated using electrochemical techniques, including electrochemical impedance spectroscopy and potentiodynamic polarization. The study demonstrated that MG exhibits exceptional inhibitory performance, achieving an efficiency of 92% at an optimal concentration of 3 g/L. The analysis revealed that the adsorption of MG molecules onto the steel surface follows the Langmuir isotherm model, indicating a process dominated by physical adsorption. Additionally, MG acts as a mixed-type inhibitor, effectively mitigating both anodic and cathodic reactions. These findings highlight the potential of Myrrh Gum as a cost-effective and environmentally friendly corrosion inhibitor for industrial applications, particularly in acidic environments. The use of MG aligns with sustainable practices, providing a viable alternative to traditional synthetic inhibitors and contributing to the development of green corrosion prevention strategies.
