SYNOPSIS

Carbon dioxide is one of the acid gases encountered in oil and gas industry as it is naturally present in hydrocarbon reservoirs. Although CO2 is non-corrosive when dry, it could lead to corrosion of carbon steel in the presence of water. Furthermore, despite being a weak acid, it is more corrosive than hydrochloric acid at the same pH. In this regard, the effect of CO2 corrosion on carbon steel must be accounted in the design of assets such as piping and pipelines. With the current effort towards net zero carbon emission which involves dense-phase CO2 transportation, the potential for catastrophic CO2 corrosion rates must not simply be disregarded.

In this half-a day course, the participants will learn the fundamental of CO2 corrosion comprising the following:

• Basic chemistry of CO2-water system
• Mechanistic theory of CO2 corrosion
• The effect of flow on CO2 corrosion
• Top-of-the line corrosion

After the completion of the course, the participants will learn how to develop a simple CO2 water chemistry model, the homogeneous and heterogeneous chemical reactions involved in CO2 corrosion, the mechanistic effects of the influencing parameters on CO2 corrosion which includes the effect of mass transfer, momentum transfer, and a multiphase flow, and top-of-the line corrosion.
