Material performance in low temperature components (e.g., heat exchangers) of the natural gasand coalfired direct supercritical CO2 power cycle systems is a concern because a highly corrosive environment is formed when aqueous condensation takes place in water saturated CO2. The corrosion behavior of Grade 91 and 347H steels was investigated in oxygenated water saturated with CO2 at 8 MPa and 50°C, 100°C, 150°C and 245°C. Both Grade 91, a ferritic-martensitic steel, and 347H, an austenitic… CONTINUE READING
