Abstract

Corrosion inhibition performance of an environmentally friendly compound, 8-hydroxyquinoline (8-HQ), on X60 steel was investigated in 15% hydrochloric acid (HCl), which simulate oil well acidizing environment. Efficacy of the inhibitor was examined utilizing weight loss, potentiodynamic polarization (PDP), electrochemical frequency modulation (EFM), linear polarization (LPR), and electrochemical impedance spectroscopy (EIS). Results show increased inhibitor efficiency with increase in concentration of 8-HQ and was further enhanced when iodide ions were added. The potentiodynamic polarization measurement illustrates the mixed type behavior of 8-HQ. Scanning electron microscopy (SEM) with energy dispersive X-ray (EDX), and Fourier transforms infrared (FT-IR) spectroscopy, were utilized to examine corrosion products and results indicate a layer being formed on the X60 steel by 8-HQ that protects the steel from further corrosion.
