Assessment of corrosion control by pH neutralisation in the presence of glycol at low temperature
Source abstract
Abstract
Abstract The effect of pH controlled by n -methyldiethanolamine (MDEA), partial pressure of CO 2 , and monoethylene glycol (MEG) on corrosion behaviour of carbon steel (X65) at 10 °C was investigated. Linear polarisation resistance and electrochemical impedance spectroscopy techniques were used. The optimum pH which yielded reasonable corrosion rate reduction was 6.5–7. While demanded impractical concentration of MDEA, increasing pH further to 8.5 marginally decreased corrosion rate as the reduction of bicarbonate ions became a dominant cathodic reaction. The double layer capacitance decreased in the presence of MEG indicating the adsorption of MEG at the steel surface and reduced corrosion rate.
