“…Additionally, Table demonstrates that the shift of corrosion potential induced by BAAs is lower than 85 mV. As a result, BAAs are classified as mixed-type inhibitors. ,, The anodic and cathodic Tafel slopes are nearly similar with rising BAA concentration, suggesting that the inhibitors are not involved in the corrosion process . Furthermore, both BAAs reduced 90 times the corrosion rate (CR) of MS compared to the blank and provided a maximum protection value of 98.9% at 0.1 wt %.…”

Gas hydrate and corrosion inhibitors are widely used to ensure a successful and economic hydrocarbon stream flow inside oil and gas pipelines. However, compatibility problems are observed during their co-injection into the flowlines as they have different molecular chemistry. Using anti-agglomerant hydrate inhibitors is an effective method to control the gas hydrate plugging risk in deep-water hydrocarbon flow lines or throughout drilling operations. Here, oleic acid was used to develop the first class of biosurfactants as anti-agglomerant and corrosion inhibitors using click chemistry for flow assurance applications. The results of high-pressure autoclave showed that both bio-based anti-agglomerants (BAAs) significantly inhibited gas hydrate agglomeration, and the value of torque remained constant during the hydrate formation process. The hydrate particles were effectively dispersed in liquid paraffin in the presence of 1 wt % of BAA1 or BAA2. In addition, molecular dynamic simulation revealed that the headgroup of BAA1 was adsorbed on the hydrate surface, and its alkyl chain dispersed the hydrate formed in the hydrocarbon phase as a slurry. According to electrochemical measurements, both BAAs were highly efficient inhibitors for the prevention of mild steel corrosion in saturated H2S and CO2-simulated oilfield water. BAA1 and BAA2 completely protected the steel in the corrosive medium by 99 and 98.8%, respectively, at 0.1 wt %. Moreover, the adsorption of BAA1 molecules on the steel surface was both physically and chemically in a direction that was almost parallel to the surface. Such adsorption provides the maximum surface coverage against corrosion. These findings suggest that oleic acid can be used as a potential starting material to develop eco-friendly inhibitors for flow assurance in oil and gas pipelines.

“…This exchange of electrons consequently results in the generation of a protective organic layer that coats the surface of the metal and preserves it from corrosion [43,48,[52][53][54]. Electron acceptors, also called LUMOs, are parts of an inhibitor's structure that are responsible to take electrons from a surface with a lot of electron density, like the surface of a metal [47,49,50]. As a result of the exchange of lone pair electrons between heteroatoms (N and O) and the vacant iron d-orbital, which consequences in a moderate rise in surface absorption potential, it is presumed that adsorption on the surface of the metal will be signi cantly greater.…”

Three synthesized Schiff base named 2,2’- (((2,2-dimethylpropane-1,3-diyl)bis(azanediyl)bis(methylene)disphenol (I1), 4,4’- (((2,2-dimethylpropane-1,3-diyl)bis(azanediyl)bis(methylene)bis(2-methoxyphenol) (I2) and 6,6’- (((2,2-dimethylpropane-1,3-diyl)bis(azanediyl)bis(methylene)bis(2-methoxyphenol) (I3) were evaluated as corrosion inhibitors for API 5L grade B steel in the artificial seawater by electrochemical impedance, polarization and Quantum chemical calculations methods. The results showed that all three compounds act as good inhibitors for carbon steel, but the I3 has the best inhibition efficiency of about 58% at 1mg/L. The results of density functional theory method were consistent with the experimental results.

Chitosan microspheres (CSM) loaded with synthesized Gemini imidazolium‐based ionic liquids ([C2(Bim)2]Cl2@CSM and [C6(Bim)2]Br2@CSM) are constructed as smart corrosion inhibitors to protect N80 steel in hydrochloric acid solution. The optimal inhibition efficiency of [C2(Bim)2]Cl2 and [C6(Bim)2]Br2 at 300 mg L−1 reaches 94.68% and 95.96%, respectively, indicating mixed‐type inhibition behavior. On this basis, the prepared [C2(Bim)2]Cl2@CSM and [C6(Bim)2]Br2@CSM can proactively identify corrosive environments and protect the metal. The microspheres are pH‐responsive owing to the presence of Schiff‐base C═N bonds and the loaded inhibitors can be released rapidly in acidic environment. Released inhibitors are delivered to corroded sites and synergistically interact with decomposed microspheres for enhanced corrosion inhibition effect.
