Abstract
Corrosion of pipeline remain a major challenge in the oil and gas industry. Corrosion in oil and gas pipelines is an electrochemical process causing significant material degradation, leading to leaks, ruptures, and, on average, 50%–70% of pipeline failures. It is driven by environmental factors or contaminants such as CO2, H2S and water. Internal corrosion slows or decreases the production of oil and gas when associated with free water and reacts with organic acid. The aim of this study is to characterize the corrosion of carbon steel and surface film composition in well deaerated environment (3.5 wt. % Nacl) using the X-Ray Photoelectron Spectroscopy (XPS). The XPS characterization focused on identifying the chemical states of Fe, O, and C on the surface, revealing that corrosion products were primarily composed of a FeCO3 film, with traces of iron oxides (FeO), or (FeOOH). The results shows that the XPS analyses on the samples reviewed some of the elements are absence on addition of HAc to the solution. The Fe 2p spectra shows peaks corresponding to metallic iron, (FeO) from the substrate and Fe2+ and Fe3+ states from the corrosion products with Fe2+ in FeCO3 being dorminant in the passive film. Similarly, A prominent peak at approximately 290.5 eV, characteristic of the carbonate ion, CO32- in FeCO3 confirmed the formation of iron carbonate.The oxygen spectra were deconvoluted into multiple states, highlighting the presence of O2- and CO32-
