Augmentation of Polyethylene Terephthalate Reusability as Efficient Corrosion Inhibitors in Oilfield Protection: Synthesis, Evaluation, and Antibacterial Study

In the presented study, polyethylene terephthalate was recycled using chemical modification process to obtain efficient corrosion inhibitors and biocides for application in oil fields as additives. The prepared compounds were fully characterized using infrared spectroscopy and proton magnetic resonance spectroscopy. The prepared compounds were evaluated as corrosion inhibiting additives using 50-400 ppm for protection of carbon steel in aqueous H2SO4 medium (1 N) at 25(o)C. The biological evaluation was presented by using minimum inhibiting concentration and inhibition zone diameter evaluation. The prepared compounds showed high efficiencies during prevention of carbon steel in aqueous H2SO4 medium (1 N) and prevented effectively the growth of sulfate reducing bacteria.
