Modeling Analysis of Corrosion Behavior of Carbon Steel in CO2 Loaded Amine Solutions

Abdelbaki Benamor and Mohammed Jaber Al-Marri
Abstract—A mathematical model simulating the corrosion behavior of carbon steel in aqueous amine-CO2 environment was developed and used to analyze the corrosion phenomena in CO2 loaded amine solutions. A mechanistic corrosion model is applied to identify the most important agents responsible for the corrosion behavior of carbon steel. The model incorporates an equilibrium model based on an activity coefficient approach according to Debye-Huckel theory and mixed potential theory to simulate the concentration of chemical species and polarization behavior taking place at a metal-solution interface in a DEA-CO2-H2O system. Simulated anodic and cathodic polarization curves were established on the basis of the calculated species concentration to represent the hypothetical oxidation and reduction behavior which were compared to the experimental curves to come out with the best fit revealing the most important corroding agents.

Index Terms—Corrosion model, diethanolamine, carbon dioxide, equilibrium model, mixed potential theory, polarization curve.
