There are no recognized standards for corrosion testing in dense phase CO2 with impurities. The main experimental challenge is impurity control. The concentration of water and other impurities (SOx NOx O2 H2S CO amines glycols) is very small and the impurities are therefore consumed fast if they take part in the corrosion process or other bulk phase reactions.The paper discusses the experimental challenges and the experiences with various types of autoclave systems that have been used for testing in recent work. The paper also discusses the functionality and capability of a new dynamic test system that allows continuous impurity renewal and concentration control.
