“…The corrosion caused by H 2 S and CO 2 is among the most frequently investigated forms of corrosion in the gas and oil industry. , Generally, this is ascribable to the fact that the natural gas/crude oil obtained from a gas well or an oil reservoir typically contains a considerable amount of H 2 S and CO 2 . , In the oil and gas industry, the primary CO 2 corrosion-related concern is that the corrosion caused by CO 2 is capable of causing failures in facilities, in particular, the transmission pipelines and the main downhole tubing, interrupting the production of hydrocarbons . Adding inhibitors is one of the most effective and universal approaches to mitigate steel corrosion. , Corrosion inhibitors are employed through batch treatments, squeeze treatments, or continuous injection systems. Most corrosion inhibitors include the compounds containing nitrogen that serve through the formation of a protective film on the surface of the steel. , Quaternary ammonium salts, phosphate ester surfactants, benzimidazole, thiadiazole, imidazoline, and amidoamine compounds are widely used as inhibitors to prevent CO 2 –H 2 S corrosion in flow lines. ,,,, …”

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.

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.

“…To quantitatively determine the adsorption energy ( E ads ), we can employ the following equation: ,− E ads = E total − ( E clay + E MB + E water ) where E ads represents the adsorption energy, E total is the total energy of the system, E clay signifies the energy of the clay surface, E MB denotes the energy of the MB molecule, and E water represents the energy of the surrounding water molecules. By solving this equation, we are equipped with a precise measure of the adsorption energy, which is instrumental in unraveling the intricate dynamics of the adsorption process. ,,, …”

The purpose of this research was to learn more about the primary and secondary properties of Moroccan natural clay in an effort to better investigate innovative adsorbents and gain access to an ideal adsorption system. Scanning electron microscopy coupled with energy-dispersive X-ray spectroscopy analysis (SEM-EDX) and X-ray fluorescence were employed for identification. SEM revealed clay grains, including tiny particles and unevenly shaped sticks. First-and second-order rate laws, representing two distinct kinetic models, were applied in the kinetic approach. Adsorption of dye MB onto natural clay was studied, and the results agreed with the 2 s order model. The significant correlation coefficients support the inference that the adsorption process was governed by the Langmuir model. Subsequent DFT analyses demonstrated that the methylene blue dye's HOMO and LUMO surfaces are dispersed across most of the dye's components, pointing to a strong interaction with the clay. To determine how the dye might be adsorbed onto the clay, we employed quantum descriptors to locate its most nucleophilic and electrophilic centers. Endothermic reactions are evident during the MB adsorption process on clay, as indicated by the positive values of ΔH 0 and ΔS 0 (70.49 kJ mol −1 of RC and 84.19 kJ mol −1 of OC and 10.45 J mol −1 K −1 of RC and 12.68 mol −1 K −1 of OC, respectively). Additionally dye molecules on the adsorbent exhibit a higher order of distribution than in the solution, indicating that the adsorption process is spontaneous.
