Supercritical C_O2 storage has been gaining more attention due to its wider application. It is one of the desirable solutions for reducing C_O2 emission, which is an important contributor to the global climate crisis. In other cases, some of the early applications were focused on the oil and gas industry, by using supercritical CO₂ to sequence the mature wells for better production ^[1],[2]. In those environments, C1018 carbon steel was extensively used, due to its good balance of toughness, strength, and ductility as well as its excellent weldability.

Electrochemical Assessment Of The Influence Of Temperature On The Pitting Corrosion Reistance Of Metallic Materials In Brines

Several industrial applications including the chemical industry and oilfield technology involve frequently halide-containing streams at elevated temperatures, that challenge the pitting corrosion resistance of metallic materials. Pitting susceptibility becomes not only a reject criterion for materials selection during the design stages of engineering components used in these applications. It also constitutes a significant limiting factor to the service life of these components once in service. Therefore, the characterization of the pitting corrosion resistance of metallic materials including the influence that operational factors can have on material’s susceptibility is crucial.

Electrochemical Behavior of the Austenitic Stainless Steel Susceptibility to Sulfide Stress Cracking in H2S Containing Brines

Austenitic stainless steels are widely in use in oil & gas production environments providing effective protection for mitigation of general corrosion due to the presence of CO2 in the produced fluids. However there is little agreement on the service limits when exposed in environments that contain H2S particularly in relation to the susceptibility to chloride stress corrosion cracking (SCC) assisted by H2S.This paper presents the results obtained from the evaluation of the electrochemical behavior using a combination of direct and alternate current methods of the passive layer formed by 316L stainless steel in the presence of brines of different ionic strength in equilibrium with a gas phase at 400 psi containing up to 60% mol of H2S (bal. CO2). The objective of the study is to evaluate the effects of temperature H2S and Cl- concentration on the pitting onset and the likelihood of SCC.The results obtained indicate that the decrease of the pitting potential is consistent with the passive layer formed on the 316L stainless steel increasing the electron donor carrier density at constant temperature. In this context the Cl- content in the brine exerts a larger effect than the H2S activity. The solution temperature was found to push the pitting and open circuit potential in more active direction due to the increase of kinetics effects independently of the H2S activity.The increase in the susceptibility to SCC was found to be proportional to the H2S content in the brine at constant temperature and chloride level; however the threshold H2S content to induce SCC is shown to increase with the brine ionic strength. This behavior is consistent with the observed reduced SCC susceptibility at higher chlorides and the presence of metastable pitting which is intensified by the activity of H2S .

Electrochemical Behavior Of Transmission Pipeline Steels In Supercritical Carbon Dioxide

High-pressure steel pipeline is a common, cost-effective method for transporting CO₂ from its point of capture to storage sites¹. In pipeline transport systems, CO₂ is mostly transported in its liquid or supercritical phase, depending on the operating pressure^2,3, which requires compression of CO₂ gas to a pressure above 80 bar (Figure 1) and avoid a two-phase flow regime in the steel pipelines. In the USA, the longest CO₂ pipelines, which transport more than 40 MtCO₂ per year from production point to sites in Texas, where the CO₂ is used for enhanced oil recovery (EOR), operate in the “dense phase” mode and at ambient temperature and high pressure.

Aluminum alloys have high strength to weight ratio, and during the years they have been used successfully in the maritime industry, due to their good corrosion resistance when correctly applied (e.g., properly selected). In the subsea environment, the oil and gas industry currently uses aluminum alloys for Remotely Operated Vehicle (ROV), but due to its limited information regarding long-term application in seawater, these alloys are not generally selected for subsea structural purposes. The aim of the current paper is to compare the performance of three different aluminum alloys through electrochemical tests in artificial seawater and under accelerated intergranular corrosion (IGC) tests. Samples were tested through potentiodynamic polarization (ASTM(1) G61), under aerated and de-aerated environments, and in order to compare their IGC resistance, they were tested following ISO(2) 11846 (method B). The polarization curves revealed that the open circuit potential (OCP) increased when the solution moved from de-aerated to aerated. Additionally, no improved performance was seen from any alloy tested concerning pitting and repassivation potential, even when subjected to different aeration conditions. Finally, the IGC testing was satisfactory to distinguish the alloys’ IGC resistance.

Electrochemical Corrosion Analysis Of Stainless Steels In LALM Pyrolysis Bio-Oil With Organic Corrodents

Biomass-derived pyrolysis oils (bio-oils) are recognized as a renewable energy source that could
aid in the reduction of fossil fuel use. Bio-oils exhibit higher corrosivity to common ferrous alloys because the oils contain organic acids and water. A series of corrosion studies were previously performed to determine the corrosion rates of ferrous alloys exposed in bio-oils for a quantitative evaluation of the material compatibility. The key information from these previous studies is that ferrous alloys with more Cr, Ni, and Mo are needed for compatibility with bio-oils.

Electrochemical Corrosion Behavior of Carbon Steel With and Without Residual Elements

Product Number: 51320-14245-SG

Publication Date: 2020

Residual elements (RE) in carbon steel, not specifically included in the specified steel, appear to influence the corrosion rate under certain conditions, especially in services involving hydrofluoric acid (HF). The relative proportions of RE, specifically %C, %Ni, %Cu, and %Cr in carbon steel base and weld metals used in refineries, especially in alkylation processes with HF as the catalyst, significantly impact corrosion behavior. Studies described in the literature show corrosion damage with high RE (Cu + Ni + Cr >0.20) components as compared to low RE (Cu + Ni + Cr <0.20) components.

In this study, electrochemical corrosion testing was performed on a 3-inch pipe elbow section with high REs that had developed a through-wall leak in service. Test results were compared to those obtained on a similar pipe elbow section with lower REs. The samples were exposed to 50% HF at room temperature and at 65°C. Linear polarization resistance (LPR) corrosion rates were measured at both temperatures. Potentiodynamic (PD) polarization scans were performed on samples of low and high RE steel exposed to 50% HF at room temperature.

Test results indicated that LPR corrosion rates were higher for the high RE carbon steel samples than for low RE carbon steel samples at both temperatures. PD scans showed that the critical current densities were higher for high RE steel than for low RE steel.

The electroplating of aluminum has represented a challenge for the coatings industry for decades. The reactivity of aluminum metal leads to a very negative reduction potential. This leads to abundant gas evolution instead of aluminum reduction in water. Current aluminum deposition technology overcomes this limitation by excluding oxygen and water from the process with rigorously dry solvent and airtight plating tanks.
