Assessing Comprehensive Mechanistic CO2 Corrosion Modeling Methods and Their Impact on Predicted Corrosion Behavior

In this work, two comprehensive mechanistic models of aqueous carbon dioxide (CO2) corrosion produced by Nordsveen et al.1 and Kahyarian et al.2 17 years apart are recreated and compared to highlight the evolution in understanding. The differences between the models include the role of carbonic acid at the surface, whether it is directly reduced or acts as a buffering agent, as well as different mechanisms for the anodic response, and varying temperature responses of multiple input variables. Through recreation and validation of these models using the same software, key comparisons are made to understand the effect of these changes on predicted corrosion rate, surface pH, and speciation through the boundary layers. These values are plotted across a range of input parameters to investigate how the change in scientific understanding influences predictive response of corrosion models.
