Resumo

Carbon steel corrosion in CO2-saturated solutions, simulating the produced water generated in oil and gas extraction, was investigated using weight loss, electrochemical measurements and surface characterization. The effectiveness of two isatin compounds, N-morpholine-isatin (MI) and N-morpholine-3-isatin-thiosemicarbazone (MIT) as corrosion inhibitors in these highly saline media was also evaluated. Only MIT was shown to act as a corrosion inhibitor for carbon steel immersed in both of the simulated produced water solutions evaluated. The impedance results corroborated the corrosion mechanisms commonly accepted in the literature.
