Review of Corrosion of Carbon Steel in CO2 – Containing Environment of the Oil and Gas Industry: Mechanism Understanding to Prediction Mode

Abstract

CO₂ corrosion has been known as one of the major mode of failure in a lot of the steel process equipment of hydrocarbon production all over the world. Hence, the comprehensive understanding of CO₂ corrosion is essential to establish the robust design, operations and integrity of the hydrocarbon production process. This paper highlights the modern understanding of CO₂ corrosion mechanisms for steels used in oil and gas production. The special attention is also paid to the important parameters affecting the protectiveness of steel under the attack of CO₂ corrosion. Besides, the empirical model for practical engineering application to predict the rate of this specific damage is also presented.
