“… 84 There was a threshold pressure (about 10 MPa) in the transported s-CO 2 pipeline, beyond which the corrosion rate increased significantly with the pressure. 82 In Figure 8 E, it can be observed that the solubility of H 2 O in s-CO 2 exhibits two distinct trends, which are divided by the phase transition point. When in gaseous CO 2 , the solubility of H 2 O decreases logarithmically with increasing pressure.…”
