Several types of corrosion inhibitors were evaluated. Active ingredients of those inhibitors
included long chain amines, fatty amides, imidazolines, fatty acids and their salts. Inhibitors
were tested at the concentration range of 50 - 200 ppm in the electrolyte and
electrolyte/hydrocarbon mixture in the presence of CO2 and H2S in static and dynamic
conditions. Several evaluations were performed when corrosion inhibitors were added into
electrolyte containing flow modifiers. The results, which include the corrosion and
electrochemical testing data, show that generally tested corrosion inhibitors are effective in
studied range of flow rates and compatible with flow modifiers.
