A novel nanocomposite as a corrosion inhibitor in Halfaya Oilfield

Abstract

Abstract The oil industry faces several challenges, like corrosion. The cost of erosion reaches billions of dollars in the global economy annually. So, this work aims to prepare a new nanocomposite (ZrO2.B2O3-[BIT]) and study its effectiveness in preventing corrosion. In addition, the analysis and surface morphology techniques will be used to study the prepared nanocomposite. The Halfaya oilfield in southern Iraq and the industrial facilities included in this oil field, including oil tanks, transport pipelines, and various equipment, were chosen to study the inhibition efficiency of the ZrO2.B2O3-[BIT] for a variety of reasons, including environmental and technical. The corrosion inhibition activity of the prepared nanocomposite on carbon steel (CS.45) alloys and the corrosion medium was a solution of hydrochloric acid (1M) was tested in this study. Several tools were used to evaluate, including XRD, EDX, AFM, FESEM, TEM, FT-IR, and 1H-NMR spectra. The results obtained by the electrochemical corrosion test cell (Tafel plots) showed a very high inhibition efficiency ZrO2.B2O3-[BIT] reached 99.4% at a concentration of 100 ppm, and the prepared nanocomposite inhibitor type was a mixed inhibitor. This compound is an effective tool in preventing corrosion and an important cost factor.
