Abstract
A model of electrochemical reactions occurring in a water — CO2 system is presented that takes into account the following electrochemical reactions: hydrogen ion reduction, carbonic acid reduction, direct water reduction and anodic dissolution of iron. Performance of the model is demonstrated through a study of the effects of some key parameters in CO2 Corrosion: pH, temperature, velocity and CO2 Partial pressure. The predictions made with the present model are compared with performance of the other best known CO2 corrosion prediction models. The present model performed similar to the latest version of the model of deWaard and Lotz. Compared to previous models, the present model gives a much clearer picture of the corrosion mechanisms and of the effect of key parameters.
