Highly Biodegradable Corrosion Inhibitors Derived from Sunflower Oil for Mild Steel Corrosion in CO₂- and H₂S-Saturated Oilfield-Produced Water

Energy & Fuels, Journal Year: 2024, Volume and Issue: 38(11), P. 9529 - 9545

Published: May 20, 2024

Sour gas reservoirs represent significant sources of energy with substantial development potential, playing a vital role in enhancing security and diversity. However, the production processing sour pose serious challenges as result its corrosive nature. The literature reveals lack efficient green inhibitors for media, because traditional often raise environmental concerns. Here, sunflower oil was employed to develop novel quaternary ammonium salts based on pyrrolidine (PyQAs) piperidine (PiQAs), serving highly biodegradable effective corrosion inhibitors. synthesis process involved straightforward two-step reaction under mild solvent-free conditions. Experimental results demonstrated remarkable 95% reduction rate presence PyQAs PiQAs. PiQAs exhibited higher performance, achieving 95.2% inhibition efficiency at concentration 70 × 10–5 M. Quantum calculations indicated that PiQAs, narrower band gap enhanced electron transfer ability, emerged more inhibitor. Moreover, molecular structures particularly electron-donating alkyl chains ester groups, facilitated their adsorption onto steel surface. mechanism attributed formation dense film surface, which hindered transport ions decreased electrochemical reactions associated corrosion. Atomic force microscopy images showed addition significantly reduced surface roughness. Furthermore, both were biodegradable, biodegradation degrees 57.8 53.1%, respectively, highlighting compatibility. These compounds offer promising balance performance biodegradability, making them attractive alternatives industrial applications.
