“…Compared with the condition containing only CO 2 , the cathodic reaction rate could be accelerated, and reduce the formation probability of FeCO 3 due to the conversion of FeCO 3 into Fe 2 O 3 in the presence of O 2 [ 24 ]. Previous studies mainly focus on the influence of CO 2 , microorganisms, temperature, and Cl − on steel corrosion [ 25 , 26 ]. However, the impact of DO on the corrosion behavior of steel in a shale gas environment remains uncertain.…”

In this study, the corrosion behavior of N80 and TP125V steels was delved firstly into produced water from shale gas fields containing CO2-O2. Moreover, the localized corrosion of these steels was investigated to elucidate the effects of aerobic and anoxic on steel corrosion. The results indicated that the corrosion rates of N80 and TP125V steels under aerobic conditions were lower compared to those in the presence of CO2-O2. Specifically, at temperature of 100 °C and with dissolved oxygen (DO) concentration of 4 mg/L in the CO2-O2 environment, the N80 and TP125V steels exhibited the highest corrosion rate, with values of 0.13 mm/y and 0.16 mm/y, respectively, as determined by specific weight loss measurements. Conversely, these rates decreased to 0.022 mm/y and 0.049 mm/y under aerobic conditions. Furthermore, severe localized corrosion of N80 and TP125V steels with a DO concentration of 4 mg/L was also observed in the CO2-O2 environment. Finally, it was evident that pitting corrosion is the predominant type of corrosion affecting N80 and TP125V steels in the produced water from shale gas fields.

“…Due to the abundance of lone pair electrons and π electrons, its derivatives were widely studied as corrosion inhibitors. [16][17][18][19][20] However, the influence of functional groups on the properties of thiadiazole had not been investigated in depth and detail in the literature.…”

Corrosion inhibitors could significantly reduce the corrosion effect of seawater on carbon steels, which were widely used in seawater cooling systems and seawater desalination systems. The corrosion inhibition properties of 1,3,4‐thiediazole (TD) and 2‐mercapto‐1,3,4‐thiadiazole (MTD) and their relationship with molecular structures were systematically studied by experimental and theoretical methods. TD and MTD were composite corrosion inhibitors with the higher proportion of cathodic corrosion inhibition, and their corrosion inhibition was based on the enlarged resistance of the electrochemical dissolution reaction of the iron. Their coverage on the surface of carbon steel and the negative movement of the potential they caused would promote each other and formed the stable adsorption. The mercaptol extended the distribution range of the negative electrostatic potential of MTD, reduced the spatial steric resistance of coordination and the energy gap of the frontier molecular orbitals, and raised the number of coordination transfer electrons, which made MTD exhibited superior corrosion inhibition performance than TD. The adsorption behavior of MTD was in line with the characteristics of Langmuir adsorption and was the combination of physical adsorption and chemical adsorption. Its adsorption form was laminated adsorption, and it was conducive to the formation of feedback bonds, which led to high stability of adsorption.
