Corrosion Behavior of Steels in Supercritical CO 2 for Power Cycle Applications
In order to understand issues with corrosion of heat exchanger materials in direct supercritical carbon dioxide (sCO 2 ) power cycles, a series of autoclave exposure experiments and electrochemical experiments have been conducted. Corrosion behaviors of 347H stainless steel and P91 martensitic-ferrtic steel in sCO 2 environment have been compared. In autoclave exposure tests performed at 50°C- 245°C and 80 bar. Mass change measurements, surface characterization, and corrosion product analysis have been conducted to understand the corrosion behavior of steels in sCO 2 containing H 2 O and O 2 . Electrochemical tests performed at room temperature and 50°C, a simulation environment of water condensation phase with dissolved CO 2 was prepared to evaluate the corrosion resistance of materials. From both types of experiments, generally 347H showed higher corrosion resistance than P91.
