Download or read book Modelling the Role of Acidic Species on CO2 Corrosion Prediction written by Mohamad Azwan Mohd Ghazali and published by . This book was released on 2013 with total page 47 pages. Available in PDF, EPUB and Kindle. Book excerpt: The presence of acetic acid (HAc) in formation water of oil and gas reservoirs has long been suspected to contribute to the CO2 corrosion rate. The prediction model has been developed based on mechanistic theories which is involved the fundamental of electrochemical reaction for partial cathodic and anodic process on the metal surface. By using this prediction model, the corrosion behaviour of carbon steel in the presence of HAc in combination with pH and temperature at simultaneously has been investigated. The corrosion prediction model was verified by comparing calculated corrosion rates with the corrosion data obtained from various literature sources and corrosion prediction software's and it's showed a good relationship in correlation and regression relationship and provided high precision in standard error estimation.From the findings, electrochemical measurements have shown that the presence of acetic acid affects predominantly the cathodic reaction and increased the rate of corrosion, which is agreed well with the general understanding of the CO2...

Book Corrosion of Stainless and Carbon Steel in Aqueous Amine for CO2 Capture

Download or read book Corrosion of Stainless and Carbon Steel in Aqueous Amine for CO2 Capture written by Kent Billington Fischer and published by . This book was released on 2019 with total page 448 pages. Available in PDF, EPUB and Kindle. Book excerpt: Post-combustion carbon capture and storage with amine absorbents is a key technology needed to provide low-cost decarbonized electricity. Improving understanding of corrosion by amines may reveal a solvent system compatible with carbon steel, which would reduce plant capital costs. Corrosion of stainless and carbon steel in aqueous monoethanolamine (MEA) and piperazine (PZ) has been measured. High temperature amine corrosion was measured in a bench-scale pressure vessel and iron solubility in amines was screened in stirred reactors. Corrosion was measured at two PZ pilot plants and one MEA pilot plant, using coupons and electrical resistance probes. Corrosion products were characterized by SEM and powder X-ray diffraction. Carbon steel (C1010) often performs well in 5 molal PZ up to 150 °C due to the formation of a passivating FeCO3 layer. This layer is promoted at high temperature, high CO2 loading, low solution velocity, and in amines with low Fe2+ solubility. FeCO3 formation is favorable at high temperature because Fe2+ solubility decreases and the kinetics of FeCO3 formation are faster. This also means that FeCO3 is not observed at low temperature. Despite this, carbon steel performs well at low temperature due to slower kinetics of metal oxidation. Depassivation and high corrosion of stainless steel (316L) can occur in amine solutions at high temperature (150 °C) when conditions are relatively anoxic and reducing. Performance of stainless at high temperature in PZ suggests that it can be pushed into and out of the passive state by small process changes, such as different flue gas O2 concentrations. However, stainless performs well in both MEA and PZ in pilot plants at ≈120 °C. Fe3+ corrosion products are generated in the absorber, then reduced to Fe2+ in the high temperature, anoxic conditions of the stripper. In this way, carried-over Fe3+ is responsible for oxidation of amine and corrosion at high temperature. Certain highly corrosive amines also have high Fe2+ solubility. Ethylamines like MEA are likely the correct chain length to form stable complexes with Fe2+ in solution. Stable Fe2+-amine complexes cause high Fe2+ solubility, which prevents FeCO3 formation and leads to high corrosion

Book Screening and Evaluating Environmentally Friendly Corrosion Inhibitors for Amine Based CO2 Absorption Process

Download or read book Screening and Evaluating Environmentally Friendly Corrosion Inhibitors for Amine Based CO2 Absorption Process written by Sureshkumar Srinivasan and published by . 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.

Book Electrochemical Model of Carbon Dioxide Corrosion in the Presence of Organic Corrosion Inhibitors

Download or read book Electrochemical Model of Carbon Dioxide Corrosion in the Presence of Organic Corrosion Inhibitors written by Juan M. Dominguez Olivo and published by . 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.

Book Corrosion Inhibition Performance of Copper Carbonate in CO2 Absorption Process Using Aqueous Solution of Monoethanolamine

Download or read book Corrosion Inhibition Performance of Copper Carbonate in CO2 Absorption Process Using Aqueous Solution of Monoethanolamine written by Immanuelraj Soosaiprakasam and published by . This book was released on 2007 with total page 292 pages. Available in PDF, EPUB and Kindle. Book excerpt: Corrosion is one of the most severe operational problems in CO2 absorption processes, which use aqueous solutions of alkanolamines, especially when carbon steel is used for plant construction. Corrosion inhibitors are widely applied used in this process to suppress severe corrosion to an acceptable level. However, currently available corrosion inhibitors are heavy metals, which are toxic to human health and the environment, making solvent handling and waste disposal more difficult and costly. This work evaluated a low-toxic corrosion inhibitor, copper carbonate (CuCO3), as a replacement for toxic corrosion inhibitors. An inhibition evaluation was performed on copper carbonate by examining its parametric effects on the corrosion rate and corrosion behavior of carbon steel.
