Corrosion mitigation behavior of mild steel in supercritical CO2 environments with varying the solution volume
Source abstract
Abstract
The corrosion behavior of X70 steel in CO 2 saturated water at 60 °C and 10 MPa was investigated by limiting the exposed solution volumes. When the specific solution volume to the exposed area was smaller than 10 mL/cm 2, it revealed the formation of protective FeCO 3 layer, leading to a significant corrosion reduction. The time-sensitive nucleation and the spatial growth of FeCO 3 grains governed the overall performance of corrosion product layers. The solution volume dependency was further explained by a diffusion-controlled deposition mechanism. It suggested a possible way to prevent CO 2 corrosion in harsh environments by generating stable FeCO 3 layers.
