“…Figure shows the potential for corrosion of carbon steel electrodes in simulated seawater with a concentration of 3.5% NaCl as a function of immersion time in both the absence and presence of a green corrosion inhibitor manufactured from recovered PET plastic waste (PETAA). For a steel electrode immersed in a 3.5% solution of sodium chloride to simulate a marine environment, the potential obviously increases to a higher negative potential initially, resulting in a brief step. − The following chemical equation states that …”

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.

Corrosion of metals and alloys is a critical challenge across various industries, leading to substantial financial losses and safety risks. The use of corrosion inhibitors has proven to be an effective strategy in mitigating this issue. This review provides a comprehensive overview of the latest advancements in the use of macrocyclic compounds and pharmacological drugs as corrosion inhibitors. These compounds exhibit unique chemical structures and functional groups, which enhance their ability to improve corrosion resistance through adsorption onto metal surfaces, thereby reducing oxidation and electrochemical reactions. The review highlights the effectiveness of these inhibitors in diverse corrosive environments and their compatibility with different metals and alloys, including steel, aluminum, and copper. Key findings reveal their superior performance in creating protective barriers and their potential for offering more sustainable, eco‐friendly solutions compared to conventional inhibitors. This review emphasizes their inhibitory effects, investigates their underlying mechanisms, and underscores the importance of ongoing research and innovation to maximize their use as effective and sustainable corrosion prevention techniques.
