عنوان انگلیسی AN INVESTIGATION ON THE PERFORMANCE OF AN IMIDAZOLINE BASED COMMERCIAL CORROSION INHIBITOR ON CO2 CORROSION OF GAS-WELL TUBING STEEL BY EIS TECHNIQUE
چکیده انگلیسی مقاله Abstract: The performance of an Imidazoline based commercial corrosion inhibitor in CO2 corrosion of a gas-well tubing steel was studied by employing Electrochemical Impedance Spectroscopy (EIS) technique. Inhibitor performance was investigated by means of its efficiency at various concentration and also its behavior at various exposure time. EIS results showed that inhibitor interaction to the electrode surface obeys Lungmuir adsorption isotherm. Interpretation of some parameters such as Rct, Rpf, Cdl, and Cpf associated to the equivalent circuit fitted to the experimental rsults showed that not only inhibitor efficiency and surface coverage improve by increasing in inhibitor concentration in the solution but also at constant inhibitor concentration both surface coverage and efficiency improve with exposure time and reach to their highest value after 4 hours.
