Abstract
Abstract The effect of flow and flow pattern of CO 2 -saturated HCl on the corrosion inhibition of carbon steel (CS) by 12-aminododecanoic acid (AA) was investigated in a square duct, rotating disk electrode (RDE), and jet impingement cell configuration. 3 mM AA provided high corrosion inhibition efficiency in the square duct and RDE configuration. However, in 1 mM AA the inhibition efficiency decreased with an increase in Re , due to desorption of AA from the CS surface. AA was found to poorly protect CS in the impingement-jet configuration at low Re , while at high Re , acceleration of CS corrosion was recorded.
