The objective of the present study was to evaluate the corrosion properties of carbon steel in supercritical carbon dioxide (CO2/brine mixtures related to the deep water oil production development. Corrosion tests were performed in 25 wt% sodium chloride (NaCl) solution under different CO2 partial pressures (4, 8, 12 MPa) and temperatures (65°C, 90°C). Corrosion behavior of carbon steel was evaluated using electrochemical methods (linear polarization resistance [LPR] and electrochemical impedanc... 更多KEYWORDS:Corrosion; Carbon steel; Temperature; Spectrum analysis;
