The objective of the present study is to evaluate the corrosion properties of pipeline steels in CO2/H2S/H2O mixtures with different amounts of water (under-saturated and saturated) related to a gas transportation pipeline. Corrosion behavior of carbon steel 1Cr steel and 3Cr steel was evaluated by using an autoclave with different combinations of CO2 partial pressure and temperature (8 MPa/25oC and 12 MPa/80oC) with 200 ppm H2S. The corrosion rate of samples was determined by weight loss measurements. The surface morphology and the composition of the corrosion product layers were analyzed by using surface analytical techniques (SEM EDS and XRD). Results showed that corrosion rate of materials in supercritical and liquid CO2 phase saturated with water is zero. However adding 200 ppm of H2S to the supercritical and liquid CO2 system caused mild corrosion (< 0.5 mm/y). Reducing water content to 100 ppm in supercritical and liquid CO2 system reduced the corrosion rate to less than 0.01 mm/y.
