CO2 TOP OF THE LINE CORROSION IN THE PRESENCE OF H2S

by Manuitt, Alvaro Camacho

Abstract (Summary)
The objective of this research work is to investigate the main parameters that affect CO2/H2S top of the line corrosion. For each experiment, top and bottom of the line weight loss corrosion measurements were performed. Higher general corrosion rates were found for the bottom of the line than for the top of the line. Tests were conducted on carbon steel coupons, using deionised water as the electrolyte in large scale flow loops at different pressures and a fixed temperature. It was found that the total pressure, partial pressure of CO2 and H2S, and HAc concentration have a strong effect on the general corrosion behaviour for both top and bottom of the line. No localized attack could be found at either top or bottom of the line in the 21 days of experiments in the presence of CO2 and H2S.
