Abstract:

Corrosion problems in surface facilities are one of the most critical challenges of the oil industry. Recently, there has been an increase in new corrosion inhibitors, particularly nanocomposite inhibitors. This study aims to prepare a novel nanocomposite TiO2·B2O3-[TBID] as a corrosion inhibitor and investigate its effect on carbon steel (CS.45). This type of alloy was chosen, and the environmental conditions are similar to the conditions of the facilities of Halfaya oilfield in southern Iraq. Analytical techniques diagnosed the prepared nanocomposite, including X-ray diffraction, Energy dispersive X-ray atomic force microscopy technique, field emission scanning electron microscope, transmission electron microscope, FT-IR spectra and nuclear magnetic resonance spectroscopy 1H-NMR. The efficiency of the prepared corrosion inhibitor was evaluated using an electrochemical corrosion test cell (Tafel plots), and the working electrode was specimens of carbon steel (CS.45) at different inhibitor concentrations of 100, 200, 300, 400, and 500 ppm in (1 M) HCl solution at temperature 35 °C. The highest inhibition efficiency (IE%), 99.91%, was at a concentration of 100 ppm of TiO2·B2O3-[TBID] inhibitor in an acidic medium.
