The aim of the present research paper is to convert daily waste materials generated by human activity at Hail city into useful petroleum additives. In this respect, novel multifunctional corrosion inhibitors working as inhibitors and flow improvers for crude oil were prepared. Polyethylene terephthalate (PET) plastic waste is used in the production of corrosion inhibitors and flow improvers for petroleum crude oil. A multifunctional corrosion inhibitor for the SABIC carbon steel in corrosive seawater for application in the petroleum industry was manufactured using PET waste that was gathered, cleaned, and used as starting materials. The PET green recycling method takes place via the Abdel-Hameed green recycling reported method. In the first step, PET waste was reacted without a solvent with a diamine to form the diamino derivative of phthalic acid amide (PETAA), which was characterized by FT-IR, 1 HNMR, and elemental analysis. In the presence of a catalyst, the used recycling method is a solvent-free green recycling process that is environmentally friendly. Chemical and electrochemical measurements were performed, and the effects of concentration and temperature were studied. The inhibition efficiency was found to increase with concentration. A maximum inhibition of 97% was obtained using 4000 ppm from the prepared PETAA inhibitor, while the efficiency decreased with temperature. Potentiodynamic polarization (PDP) data indicates the mixedtype nature of the used inhibitor. According to potentiodynamic polarization data, the inhibitor boosts polarization resistance and inhibition performance by adsorbing on the metal/electrolyte interface. The data from electrochemical impedance spectroscopy (EIS) show that the charge-transfer mechanism is the primary governing factor in the steel dissolution process. The size of the semicircle grows in direct proportion to the concentration of the inhibitor. The prepared additive acts as a flow improver (viscosity improvers and pour point depressants) for waxy crude oil, indicating that it can be used in the manufacturing of multifunctional inhibitors in the petroleum industry. The depression in the pour point temperatures depended on the concentration and composition of the additive prepared from the plastic waste collected from Hail city.

“…A large number of scientific studies have been devoted to the subject of corrosion inhibitors for steel in acidic media. [16][17][18][19][20] Hameed et al [15] conducted a study to investigate the use of Indomethacin in the form of expired drugs as a corrosion inhibitor for carbon steel in 1.0 M HCl solution using chemical and electrochemical techniques, namely, weight loss, electrochemical impedance spectroscopy (EIS), potentiodynamic polarization, and scanning electron microscopy (SEM). The results showed that expired Indocin capsules were a good inhibitor of corrosion where the inhibition efficiency reached 83% at 500 ppm of the used inhibitors.…”

The study aimed to assess the alterations in the morphology, elemental composition, and biocompatibility of infra-zygomatic crest (IZC) miniscrews, before and after their insertion in the patient’s oral cavity. The study was conducted on 16 IZC miniscrews (8 as-received and 8 retrieved). Scanning electron microscopy (SEM) was used to evaluate the miniscrew surfaces. Micrographs were obtained at ×50, ×100, and ×500 magnification. The miniscrews were subjected to Energy-dispersive x-ray (EDX) analysis to investigate the elemental composition. It was performed at four zones of each miniscrew- head, neck, body, tip. Corrosion of the miniscrews was analyzed through the potentiodynamic polarization (PDP) test by immersing the stainless steel (SS) miniscrews in an artificial saliva medium (pH 5.8) and then allowing it to obtain a steady-state open-circuit potential (OCP) for 15 min. Gingival fibroblasts were cultured using gingival tissue which was used to check the biocompatibility of the miniscrews by observing their proliferation and viability by MTT colorimetric assay. The SEM analysis showed generalized surface dullness, variable corrosion, craters, and blunting in the retrieved miniscrews. EDX analyses showed the deposition of additional elements: carbon, oxygen, calcium, and nitrogen in the retrieved miniscrews. PDP tests showed a higher corrosion rate in the retrieved miniscrews, but the results were not significant. The MTT assay showed that the cell viability was higher in the as-received group and the results were statistically significant with a p value of 0.002. It was concluded that the retrieved miniscrews exhibited morphologic surface changes in the form of dullness, blunting of threads and tips, corrosion, craters, and cracks which were not seen in the as-received miniscrews. A higher percentage of adsorbed elements were seen on the retrieved miniscrew surface. The corrosion rate assessed through the PDP test for both groups was comparable. The fibroblast cell viability was significantly reduced in the retrieved miniscrews when compared to as-received miniscrews.

“…This is accredited to the adsorption of cationic surfactants on the steel interface, forming an adsorption-film layer, which separates the metal surface from the surrounding environment [19]. The efficiency of this material as an inhibitor depends on its adsorption capacity [20]. Most of the cationic surfactants can be used as corrosion inhibitors containing O, N, S, P, heteroatoms, and or π-bonds that permit the adsorption of the surfactant molecule on the electrode interface [21,22].…”

Novel quaternary ammonium surfactants based on imines, namely, (E)-3-((2-chlorobenzylidene)amino)-N-(2-(decyloxy)-2-oxoethyl)-N,N-dimethylpropan-1-aminium chloride, (ICS-10) and (E)-3-((2-chlorobenzylidene)amino)-N,N-dimethyl-N-(2-oxo-2-(tetradecyloxy)ethyl)propan-1-aminium chloride (ICS-14) were synthesized and their chemical structures were determined by different spectroscopic approaches. The surface properties of the target-prepared surfactants were investigated. The effects of both synthesized imine surfactants on carbon-steel corrosion in 1.0 M HCl solution were investigated by weight loss (WL), potentiodynamic polarization (PDP), and scanning electron microscopy (SEM) methods. The outcomes show that the inhibition effectiveness rises with raising the concentration and diminishes with raising the temperature. The inhibition efficiency of 91.53 and 94.58% were attained in the optimum concentration of 0.5 mM of ICS-10 and ICS-14, respectively. The activation energy (Ea) and heat of adsorption (Qads) were calculated and explained. Also, the synthesized compounds were investigated using density functional theory (DFT). Monte Carlo (MC) simulation was utilized to understand the mechanism of adsorption of inhibitors on the Fe (110) surface.
