“… 43 However, it is obvious that the C–S peak in the DFDS-inhibited system is stronger with a larger integration area, which is the result of the greater coverage of the DFDS molecules on the steel surface. In the O 1s spectra, FeOOH (531.2 eV), 43 , 44 FeCO 3 (531.9 eV), 45 and C–O/CO 3 2– (529.6 eV) exist. 46 , 47 In particular, the C–O/CO 3 2– peak area was significantly larger in the system subjected to 2-FFT inhibition, indicating more corrosion products on the steel surface.…”

Two food flavors, furfuryl mercaptan (2-FFT) and difurfuryl disulfide (DFDS), were investigated as green corrosion inhibitors for the N80 steel in a CO 2 -saturated solution containing 3.5% NaCl. Experimental methods, quantum chemical calculations, and molecular dynamics simulation were employed to evaluate the effectiveness of 2-FFT and DFDS. The results of the study indicate that both 2-FFT and DFDS act as mixed corrosion inhibitors, with a dominant inhibition effect on the cathodic reaction. 2-FFT is physiochemically adsorbed on the steel surface in a tiled form through the furan ring and the − SH groups as adsorption sites. On the other hand, DFDS is chemisorbed on the steel surface through the − S−S− groups in a parallel manner. DFDS exhibits a higher tendency for electron transfer and stronger adsorption to steel compared to 2-FFT. Overall, this study highlights the potential of natural food flavors as effective and environmentally friendly corrosion inhibitors for carbon steel in CO 2saturated environments. The findings of this research can contribute to the development of sustainable and nontoxic corrosion inhibitors for the oil and gas industry.

“…It is responsible for more than 20% of pipeline system failures and about 40% of the internal corrosion in the oil and gas transportation pipelines (Brooks, 2013; Javaherdashti, 2017). As a green energy source, the shale gas field also faces a high risk of MIC, because of the fracturing fluid deriving from rivers or lakes which usually contain highly corrosive microorganisms, such as sulfate-reducing bacteria (SRB)(Feng et al , 2020). The application of antibacterial material in the service environment is an important practice for MIC control.…”

Purpose This paper aims to investigate the anti-biocorrosion performance and mechanism of the Cu-bearing carbon steel in the environment containing sulfate-reducing bacterial (SRB). Design/methodology/approach The biocorrosion behavior of specimens with Cu concentration of 0 Wt.%, 0.1 Wt.%, 0.3 Wt.% and 0.6 Wt.% were investigated by immersion test in SRB solution. By examining the prepared cross-section of the biofilm using focused ion beam microscopy, SRB distribution, bacterial morphology, biofilm structure and composition were determined. The ion selectivity of the biofilm was also obtained by membrane potential measurement. Moreover, the anti-biocorrosion performance of the Cu-bearing carbon steel pipeline was tested in a shale gas field in Chongqing, China. Findings Both the results of the laboratory test and shale gas field test indicate that Cu-bearing carbon steel possesses obvious resistance to microbiologically influenced corrosion (MIC). The SRB, corrosion rate and pitting depth decreased dramatically with Cu concentration in the substrate. The local acidification caused by hydrolyze of ferric ion coming from SRB metabolism and furtherly aggravated by anion selectivity biofilm promoted the pitting corrosion. Anti-biocorrosion of Cu-bearing carbon steel was attributed to the accumulation of Cu compounds in the biofilm and the weaker anion selectivity of the biofilm. This research results provide an approach to the development of economical antibacterial metallic material. Originality/value MIC occurs extensively and has become one of the most frequent reasons for corrosion-induced failure in the oil and gas industry. In this study, Cu-bearing carbon steel was obtained by Cu addition in carbon steel and possessed excellent anti-biocorrosion property both in the laboratory and shale gas field. This study provides an approach to the development of an economical antibacterial carbon steel pipeline to resist MIC.
