“…Finally, in addition to the tests performed in a CO 2 /H 2 S coexisting environment, two other studies reported on the inhibition of different compounds in a CO 2 coexisting environment with either O 2 or NH 3 . Hu et al [70] . studied the influence of oxygen concentration on the corrosion inhibition effectiveness of bis(2‐ehylhexyl) phosphate on the corrosion of Q345R steel in 1 wt.% NaCl solution in a CO 2 /O 2 coexisting environment (i. e. 0.05 or 3.00 mg/L O 2 and 0.02 MPa CO 2 partial pressure).…”

This review paper discusses the research work published in the last decade on the use of organic compounds and natural products as corrosion inhibitors for steel in CO2 and CO2/H2S coexisting environments. The carbon and mild steel samples tested are mostly immersed in CO2‐saturated NaCl/brine solutions or simulated oilfield waters. The influence of temperature, immersion time, CO2 partial pressure, pre‐corrosion, flow rate/rotation speed, and the synergistic effect of other compounds on the corrosion inhibition effectiveness of organic compounds and natural products is presented. Primarily, weight loss and electrochemical techniques were used to evaluate the corrosion inhibition effectiveness of these compounds.

“…EIS is widely used in the field of corrosion inhibition, which provide the corrosion inhibition behavior of corrosion inhibitor in corrosion solution. [19] Figure 5 shows the Nyquist diagram under different concentrations of inhibitor, with the increase of SMIS, the capacitance in the real axis direction increases, indicating that the inhibitor has a certain corrosion resistance. [20] From Figure 6, a peak value in the Bode diagram, indicates that Q235 carbon steel is affected by charge transfer process and double layer capacitance in SCP solution.…”

A novel imidazoline derivative has been synthesized and its molecular structure has been confirmed by IR, Raman, elemental analysis and NMR, the molecular structure of the inhibitor is similar to that of the previous research. In this paper, the inhibition performance and inhibition mechanism of the three inhibitors (SMID, SMIS and SMIF) in concrete simulation solution are analyzed and compared. The corrosion inhibition efficiency of SMIF (96.02 %) > SMIS (93.62 %)>SMID(93.01 %) in weight loss experiment, the SMIS of electrochemistry of Nyquist and potentiodynamic polarization were 89.72 % and 92.03 % respectively, which indicated that SMIS had good corrosion inhibition effect. Electrochemical experiments show that the SMIS belongs to anodic type, and the mechanism of SMIS can form a protective film on the surface Q235 and inhibit the charge transfer. The results of FTIR, EDS and XPS show that SMIS can be adsorbed on the surface of Q235, which is also confirmed by density functional theory (DFT) and molecular dynamics simulation (MD).

“…In the light of the aforementioned concerns, alluminum alloys demand protection in various process industries. Chromate conversion coatings (CCC) have been extensively used because of their excellent anti corrosion properties [7]. Additionally, corrosion inhibitors have proved themselves effective in protecting the metals against corrosion with the clear advantages concerning cost, availability, ease of use and high protection efficiency [8].…”

In spite of the fact that aluminium and its combinations are regularly used like lightweight materials in a great deal of enterprises, they experience the ill effects of low erosion resistance. Corrosion is a natural phenomena that leads to the deterioration of the metal properties through its electrochemical interaction with the corrosive environment. The costs related to corrosion can be either direct (due to the replacement and maintenance) or indirect. A few strategies and methods have been utilized to mitigate corrosion in aluminium and its compounds under various conditions. Concerns raised over climate and human wellbeing have constrained industries to search for a more appropriate option for the protection of aluminium and its alloys from corrosion. This review emphasizes on the plant extracts applied for aluminium combination consumption restraint in NaCl medium. It summarizes the different techniques used for extraction. Additionally, an understanding to the adsorption isotherms has been discussed in brief.
