The effect of electrolyte flow on the performance of 12-aminododecanoic acid as a carbon steel corrosion inhibitor in CO2-saturated hydrochloric acid

► Inhibition of carbon steel corrosion by 12-aminododecanoic acid (AA) was investigated. ► Inhibition efficiency (IE) was found to depend on AA concentration and electrolyte flow. ► 89% IE was found for 3mM AA for the rotating disc electrode configuration. ► AA accelerated CS corrosion at high flow rates in the impingement-jet configuration.
