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.

Key words: Corrosion inhibitors, electrolyte, rotation cylinder electrode, concentration, chemical nature
