Abstract

Abstract There is an increasing need in the petroleum industry to develop green products due to more severe environmental legislation. Recently, several environmentally friendly corrosion inhibitors became available commercially. We evaluated the performance of five of these commercial green corrosion inhibitors in CO2 saturated 3% sodium chloride solution with or without hydrocarbon. We used the Electrochemical Impedance Spectroscopy technique in the Rotating Cylinder Electrode system for the performance evaluation. Results showed that three of five commercial products gave acceptable inhibition performance and the performance ranking among these products also varied significantly in brines with or without 20% hydrocarbon. This indicates that partitioning characteristics of these products are different.
