This book was released on 2020 with total page 181 pages. Available in PDF, EPUB and Kindle. Book excerpt: Internal corrosion in pipelines is a significant issue in the upstream oil and gas industry. Corrosion engineers have developed strategies to mitigate corrosion, and among these, the use of organic corrosion inhibitors is one of the most widely used solutions. Corrosion inhibitors are substances that significantly reduce corrosion when added in small, typically ppm level, concentrations. Knowledge related to their efficiency, and associated mechanisms of inhibition, has been developed by conducting experiments in physicochemical conditions that simulate field environments during their application. Nonetheless, there is a lack of studies in the open literature that mechanistically define the effect of corrosion inhibitors on the kinetics of the electrochemical processes underlying corrosion. Consequently, the central objective of this research was to propose a mechanistic model that describes and predicts the effect of organic corrosion inhibitors on the electrochemical processes governing the carbon dioxide corrosion of mild steel. In order to develop the mechanistic model, corrosion studies included the electrochemical characterization of aqueous steel corrosion in the presence of known corrosion inhibitor packages (quaternary-ammonium-type and imidazoline-type) with techniques such as linear polarization resistance (LPR), electrochemical impedance spectroscopy (EIS), and potentiodynamic polarization. During these experiments, the state-of-the-art knowledge on corrosion inhibition available in the open literature related to corrosion inhibition was insufficient to explain specific experimental observations satisfactorily. This situation led to the postulation of ad hoc hypotheses to explain the effect of the organic corrosion inhibitors’ molecular structure on the observed electrochemical kinetics for the corrosion process, namely, the effects of inhibitor alkyl tail length and head group.

Available in PDF, EPUB and Kindle. Book excerpt: Corrosion product scales formed under different conditions were investigated using EIS and surface analysis techniques. Temperature, pressure and exposure time were confirmed to be the important factors influencing the degree of protection given by the scale. The morphology of corrosion scales showed an obvious correlation to their protective ability. Electron microscopy revealed two types of crystal structures on corroded steel coupons. The smaller crystals associated with one of these structures was found to contribute most to corrosion protection. Several typical CO(subscript)2 corrosion inhibitors, including an imidazoline and a quaternised amine, were studied by EIS. A multi-layer model was employed to explain the EIS characteristics and self-repairing ability of imidazoline films. A quaternised amine film is most probably a physically or electrostatically adsorbed molecular layer which forms rapidly and desorbs easily. The deterioration of films, formed by commercial batch treatment inhibitors, was found to occur in three stages which were indicated or characterised by Bode phase-angle plots. A method to determine inhibitor film persistency was developed. This method is based on determining the three stages of inhibitor film deterioration, and the continuous measurement of corrosion rate, which is accessible at the second and third stages of film deterioration.

This book was released on 2018 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: This chapter evaluated the performance of environmentally friendly organic corrosion inhibitors on carbon steel in the amine-based carbon dioxide (CO2) absorption process. The evaluation was experimentally conducted using electrochemical techniques in 5.0 kmol/m3 monoethanolamine (MEA) solutions in the absence and presence of process contaminants, namely formate and chloride, at 80°C and 0.55 mol/mol CO2 loading. The results show, in the absence of process contaminants, that 2-aminobenzene sulfonic acid, 3-aminobenzene sulfonic acid, 4-aminobenzene sulfonic acid, sulfapyridine, and sulfolane yielded 85-92% corrosion inhibition efficiencies, while sulfanilamide yielded the lowest efficiency of 20-42%. Sulfolane was the only tested inhibitor whose performance could be maintained in chloride- and formate-containing MEA solutions. On the contrary, the performance of 3-aminobenzene sulfonic acid and sulfapyridine was decreased by chloride. The performance of all the tested aminobenzene sulfonic acids was compromised by formate.
