Aqueous Corrosion and High Temperature Oxidation in Supercritical Carbon Dioxide Environments

Creator:

Teeter, Lucas

Abstract:

The corrosion resistance of steels and nickel based alloys was investigated in supercritical CO2 (sCO2). Two types of experiments were conducted. The first set of experiments were conducted in a low temperature aqueous environment to simulate conditions that would exist in direct sCO2 power cycle low temperature heat exchangers. The...

Corrosion Resistance of Alloys in Seawater and Supercritical Carbon Dioxide Environments

Creator:

Repukaiti, Reyixiati

Abstract:

The corrosion resistances of several alloys were investigated to optimize performance and cost in seawater and supercritical CO2 environments. Many alloys are prone to corrosion in seawater and/or supercritical CO2 containing impurity environments. Exposure and electrochemical experiments were conducted in both environments to evaluate alloys’ corrosion resistance. In seawater corrosion...

Corrosion Resistance of Alloys in Direct-Fired Supercritical CO₂ Power Cycle Aqueous Environments

Creator:

Repukaiti, Reyixiati

Abstract:

Using supercritical CO₂ (sCO₂) as a working fluid has increasingly gained attention in the energy industry. sCO₂ power cycles has various advantages, such as high cycle efficiency, compact turbomachinery, and potential zero CO₂ emission. Along with these benefits, materials degradation issues have also been emphasized in the last decade. Aqueous...
