Carbon Capture and Storage (CCS). The CO2 stream, captured from power plants contains highly corrosive impurities including H2O vapor, oxygen, and hydrogen sulfide. This paper presents our study on corrosion of pipeline steel in sc-CO2 containing H2O, H2S and/or O2 impurities in an autoclave.

Characterization of Oxide Scales Formed on Fe-20Cr-(20-25)Ni Alloys in Supercritical CO2

Supercritical CO2 (sCO2) has attractive aspects as a working fluid, however, above ~550°C it carburizes conventional Fe-based alloys. Evaluations of Fe-based alloys found that advanced austenitic alloys like alloy S31025 with higher Cr and Ni contents have better sCO2 compatibility than conventional stainless steels at 650°C in sCO2 for up to 2000 h exposures. To further understand the protective scale formed on alloy S31025 in 300 bar research grade sCO2 at 650°C, the thin Cr-rich scale was analyzed after 500 h using analytical transmission electron microscopy and compared to scales formed on model Fe-20Cr-20Ni and Fe-20Cr-25Ni. Typical Mn and Si rich layers were observed but a recurring observation was an O depleted region in the scales. Characterization identified a mixed O-C phase with Cr and Fe within the scale formed on both commercial and model alloys. This phase did not form after a similar 500 h exposure at 650°C in 1 bar CO2.

Compatibility Of Steels At 450°-650°C In Supercritical CO2 With O2 And H2O Additions

Product Number: 51322-18018-SG

Using supercritical CO2 (sCO2) as a working fluid is being explored for a number of power generation technologies including fossil, nuclear, geothermal, concentrating solar power (CSP) and waste heat recovery1-7.  The various sCO2 cycles are attractive because of the low critical point (31°C/73.8 bar) and the reduced work of compression compared to an ideal gas.  While CO2 is sometimes described as inert, there is a long history of component degradation in subcritical and supercritical CO2 and a particular concern about internal carburization8-16.

In recent years, several novel technologies have been proposed and developed to produce energy in a clean and sustainable way. However, in the foreseen future, fossil fuel will still be the major source to meet our needs on energy.1 The combustion of fossil fuel for power and heat is always accompanied by CO2 emission, which is believed to be in large correlation to global warming.2 To control the CO2 emission and reduce the negative effects, carbon capture and storage (CCS) has been rapidly developed in fossil fuel combustion power plants.3, 4 One of the crucial parts of CCS is the longdistance transportation of CO2, during which a large amount of captured CO2 is transported to storage sites. Pipeline network is chosen as transportation system due to its high efficiency and moderate cost.5 And the transported CO2 streams are usually compressed into supercritical CO2 (s-CO2).6

Over the years, the supercritical carbon dioxide (s−CO2) Brayton cycle has been developed as a promising working fluid to replace supercritical water (s−H2O) Rankine cycle. It could be used in various energy systems, including Generation IV nuclear reactors, concentrated solar power plants, fossil fuel thermal power plants, waster heat recovery, etc. due to its merits of high thermal efficiency, simple physical footprint, compact equipment size, high flexibility on operation, simple layout, compact turbomachinery.1

Supercritical CO2 (sCO2) has many attractive features as a working fluid including its low critical point (31°C/73.8 bar) and the reduced work of compression compared to an ideal gas. Thus, it is being explored for many different applications including fossil, nuclear, geothermal, concentrating solar power (CSP) and waste heat recovery. However, CO2 environments are known to carburize steels6-20 which limits their usage to lower temperatures (450°C21 for 9%Cr steels) than in steam boilers.
