Corrosion Inhibitors used in Pipelines Carrying Simulated Oil Well Water – An Overview and Inhibition of Corrosion of Mild Steel in Simulated Oil Well Water by Aqueous Extract of Chrysanthemum Indicum Flower- Case Study

Simulated oil well water (SOWW) is conceded out by pipelines made of several alloys for instance mild steel & L80. These alloys may undergo corrosion owing to the presence of various aggressive ions present in SOWW. To prevent this several inhibitors have been used. Several methods have been used to estimate the inhibition efficiency of extract. Weight loss study, electrochemical study like potentiodynamic polarization study & electrochemical impedance spectroscopy study, Fourier transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM), nuclear magnetic resonance spectroscopy (NMR), atomic force microscopy (AFM), and TEM have been employed in these studies. Recent developments in this field of research are presented in detail briefly. As a study Inhibition of corrosion of mild steel in simulated oil well water by aqueous extract of Chrysanthemum Indicum flower is also discussed.
