“…Utilizing natural resources will enable the achievement of both economic and environmental objectives. In several researches, plant extracts have been mentioned as prospective agents to lessen corrosion in different industrial solutions. − As reported previously, the ethanolic extract of (P.cubebaOE) contains levels of Yatein, Cbenin, cubebinone, cubebininolide, Hinokinin and cubebinin, single aldehyde, and α, β-unsaturated ketone. From the Piper cubeba, several phenolic acids and flavonoids have been found and extracted.…”

This work offers a high-performing, environmentally friendly corrosion inhibitor for carbon steel in 1 M sulfamic acid (H 2 NSO 3 H). Potentiodynamic polarization and electrochemical impedance spectroscopy were used to evaluate the anticorrosion properties of Pipper cubeba official extract (P.cubebaOE) for carbon steel in 1 M H 2 NSO 3 H at 25 to 45 °C. At a temperature of 45 °C, the P.cubebaOE reached a maximum corrosion inhibition efficiency of 96%. P.cubebaOE was also subjected to Fourier transform infrared spectroscopy in order to ascertain its primary chemical composition. Additionally, the behavior of P.cubebaOE in terms of corrosion inhibition on carbon steel was examined at the microscopic level using scanning electron microscopy. The findings demonstrate that P.cubebaOE's adsorption type on carbon steel conforms to the Langmuir adsorption isotherm model. Based on the adsorption isotherm model, the free energy was estimated to be approximately −20.0 kJ/mol, suggesting that P.cubebaOE is physically adsorbing on the surface of carbon steel. The results of the density functional theory and molecular dynamics simulations show that P.cubebaOE exhibits excellent inhibition performance on carbon steel in H 2 NSO 3 H solution and are consistent with the electrochemical experimental results. This work offers significant information on the development of environmentally friendly corrosion inhibitors for carbon steel.

Gas hydrates pose a serious flow assurance challenge due to their ability to form, agglomerate, and block subsea flowlines on relatively fast time scales, leading to the loss of production and potential safety and environmental risks. The hydrate management strategy based on antiagglomerant inhibitors has gained significant interest in recent years, particularly in long tiebacks, maturing fields, and deep-water projects. However, most of the antiagglomerants used are not environmentally friendly, and compatibility issues with corrosion inhibitors also arise during coinjection operations. Here, a new oleic acid derivative was synthesized and used to develop two formulations (OADs) as green multifunctional flow assurance chemicals to control hydrate agglomeration and corrosion risks inside oil and gas pipelines. The experimental results showed that the OADs effectively inhibited methane hydrate growth and formed a transportable hydrate slurry in a water−paraffin mixture. Moreover, 0.1 wt % OADs completely suppressed the corrosion process of carbon steel in a CO 2 -and H 2 S-saturated solution by a protection of 99.4%. Computational studies also revealed that the adsorption of OADs on the hydrate surface increased its hydrophobicity, preventing the hydrate and water droplets from aggregating or clumping together. Additionally, OADs decreased the binding energy of iron and corrosive species up to 99.5%, and corrosive ions were almost no longer in direct contact with iron. The binding energy between the inhibitor and iron indicated the formation of a stable protective film by the OAD molecules on the steel surface to protect it against acidic corrosion. These results contribute to show the potential of oleic acid as a valuable green source to develop dual-purpose antiagglomerant hydrate and corrosion inhibitors for hydrate-related safety management.
