| Abstract Scope |
Fluid-phase CO2 is a common waste product of several industrial processes which needs to be transported for safe disposal. While CO2 by itself is generally non-corrosive to metals, the presence of impurities, especially water, can cause significant corrosion. This is especially true of the steel infrastructure typically used for fluid transportation, i.e. pipelines and pressure vessels. It is important to note that there are a wide range of steel microstructures involved in the pipeline infrastructure. The designations of pipeline and pressure vessel steels specify either strength (e.g. API X-series) or chemistry (e.g. AISI 4130), both of which can encompass a wide range of microstructures while fulfilling the designation requirements. The effect of microstructure on the corrosion by wet-CO2 of a set of pipeline steels and a set of pressure vessel steels will be examined, looking at differences in corrosion rate and corrosion product formation. |
