Abstract:Investigation of corrosion inhibitors on CO 2 -saturated aqueous solution with O 2 contamination is limited. Hence, this study investigated the corrosion behavior of phosphate ester inhibitor towards carbon steel corrosion in a simulated CO 2 -O 2 environment by potentiodynamic polarization technique and electrochemical impedance spectroscopy. It was shown that the PE prevents the corrosion attack in the presence of CO 2 -O 2 , reaching an efficiency of 90.7% with 25 ppm in 3.5 wt% NaCl solution at 25 o C. Fur… Show more
