“…The use of corrosion inhibitors as an environmentally friendly, efficient, and low-cost anticorrosion method has been paid more and more attention in the production and development of oil and gas fields at home and abroad. , According to the characteristics of oilfield recovery and production increases, it takes a long time to study CO 2 corrosion inhibitors in oilfields all over the world. There are mainly five kinds of CO 2 corrosion inhibitors: (1) imidazoline and its derivatives: Zhang et al studied 2-undecyl-1-1-ethylamino-1-ethylcarboxyl quaternary imidazoline corrosion inhibitors at temperatures of 25 and 40 °C, respectively, with a CO 2 content of 3% and an Na 2 SO 4 content of 3% in saturated sodium chloride solution.…”

Oxygen-reduced air flooding (ORAF) can effectively improve oil recovery in low-permeability reservoirs, but oxygen corrosion and CO2 corrosion in downstream gathering pipelines are inevitable due to the existence of oxygen, which limits the popularization and application of ORAF. In this paper, research on the corrosion inhibitor is carried out for the gathering pipeline of an oilfield with ORAF in China. Under the conditions of a simulated onsite gathering pipeline, 6 kinds of anti-CO2 corrosion inhibitors and 6 kinds of antioxygen corrosion inhibitors were selected to evaluate and screen the effects of 20# steel by the dynamic weight loss method. Two antioxygen corrosion inhibitors KY-12 and KY-17 and one anti-CO2 corrosion inhibitor A were selected for the experiment. The corrosion inhibition rates of the three inhibitors reached 83.67, 91.49, and 78.44%, respectively, at a temperature of 40 °C and an inhibitor concentration of 1000 mg/L. Through the experimental evaluation of three primary corrosion inhibitors at different temperatures (25, 40, and 55 °C) and different concentrations (400, 500, 800, 1000, and 2000 mg/L), the KY-17 corrosion inhibitor with the best stability at different temperatures was selected, and the corrosion inhibition effect was the best at different concentrations, with the highest slow release rate reaching 92.7%. This conclusion has a good reference significance for the selection and dosage of corrosion inhibitors for downstream gathering pipelines of the ORAF oilfield.

“…Corrosion, a pervasive and insidious process, has long been a formidable adversary in the realm of materials degradation, particularly in acidic environments [1][2][3][4][5]. The deleterious effects of corrosion on industrial infrastructure, ranging from pipelines and storage tanks to bridges and machinery, have far-reaching economic and safety implications [6][7][8][9]. Acidic solutions, often encountered in various industrial processes, exacerbate corrosion-related concerns due to their corrosive nature, necessitating the development of effective corrosion inhibition strategies.…”

Corrosion poses a persistent challenge in acidic environments, necessitating the exploration of effective corrosion inhibitors. This mini-review focuses on the utilization of heterocyclic compounds as corrosion inhibitors in acidic solutions. Beginning with an overview of corrosion mechanisms in acidic environments, we delve into the diverse array of heterocyclic compounds investigated for their corrosion inhibition properties. Emphasis is placed on elucidating the mechanisms through which these compounds mitigate corrosion, ranging from surface adsorption to film formation. Recent advancements in the field are highlighted, showcasing novel compounds and formulations exhibiting promising results. A comparative analysis evaluates the effectiveness of various heterocyclic compounds, considering factors such as inhibition efficiency, cost, and environmental considerations. Despite notable successes, challenges and limitations are discussed, paving the way for future research directions. In conclusion, this mini-review underscores the significant strides made in harnessing heterocyclic compounds as corrosion inhibitors, offering a glimpse into their potential impact on addressing corrosion challenges in acidic environments.

“…The corrosion-related failures have a negative impact on the productivity and ongoing operations of these businesses. Because of the corrosion failures, various industrial and metallurgy operations, including descaling, electrolyte-based cleaning, pickling, and acidification, cause a significant loss of metallic elements throughout the surface treatment [ 6 , 7 ]. Numerous economic and safety issues are brought on by corrosion failure.…”

Recent studies indicate that surfactants are a relatively new and effective class of corrosion inhibitors that almost entirely meet the criteria for a chemical to be used as an aqueous phase corrosion inhibitor. They possess the ideal hydrophilicity to hydrophobicity ratio, which is crucial for effective interfacial interactions. In this study, a coconut-based non-ionic surfactant, namely, coco monoethanolamide (CMEA), was investigated for corrosion inhibition behaviour against mild steel (MS) in 1 M HCl employing the experimental and computational techniques. The surface morphology was studied employing the scanning electron microscope (SEM), atomic force microscope (AFM), and contact measurements. The critical micelle concentration (CMC) was evaluated to be 0.556 mM and the surface tension corresponding to the CMC was 65.28 mN/m. CMEA manifests the best inhibition efficiency (η%) of 99.01% at 0.6163 mM (at 60 °C). CMEA performs as a mixed-type inhibitor and its adsorption at the MS/1 M HCl interface followed the Langmuir isotherm. The theoretical findings from density functional theory (DFT), Monte Carlo (MC), and molecular dynamics (MD) simulations accorded with the experimental findings. The MC simulation’s assessment of CMEA’s high adsorption energy (−185 Kcal/mol) proved that the CMEA efficiently and spontaneously adsorbs at the interface.
