Modeling of uniform CO2 corrosion of mild steel in gas transportation systems: A review

The state of the art with regards the mechanistic understanding of uniform carbon dioxide corrosion of mild steel is reviewed and the corresponding mathematical models are presented. The existing predictive models are categorized into three groups, termed: empirical/semi-empirical, elementary mechanistic, and comprehensive mechanistic. With emphasis on mechanistic models, selected key publications are reviewed and the limits and advantages of each group of models are discussed. Furthermore, the ability of the existing models to be extended and account for more complex corrosion scenarios is discussed. (C) 2016 Elsevier B.V. All rights reserved.
