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 recovery^1-7. 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 carburization^8-16.

Corrosion Of 2Cr Steel In Supercritical CO2 Saturated Saline Water With Cl, S and Br Anions

Before full decarburization can be achieved, the Intergovernmental Panel of Climate Change (IPCC) suggests an applicable way of combining CO2-producing processes with the carbon capture, utilization, and storage (CCUS) chain. Except for permanent CO2 storage, the economics and efficiency of CCUS processes can be further improved by utilizing the CO2 byproduct in other industry areas. One of the promising methods is to use the captured CO2 for enhanced oil recovery (EOR).

Corrosion of Cr-Alloyed Steels in Supercritical CO2-Saturated Brine Water

In the context of urgent efforts to reduce global carbon emissions, carbon capture, utilization, and storage (CCUS) has gained prominence. Tubing and casing steels are vital materials of construction (MOC) in CCUS systems, especially in supercritical CO2 (s-CO2) environments. However, the understanding of the corrosion behavior of these steels under s-CO2 conditions is limited, which presents integrity challenges. Immersion experiments were conducted with steels containing varying chromium (Cr) levels (0.5 wt% to 16.5 wt%), including P110, P91, and SS 316. These steels were exposed to s-CO2-saturated brine water (3.5 wt% NaCl) at 50 °C and 10 MPa for durations of 10 and 100 hours. Corrosion rates were determined via weight loss measurements, and corrosion products were analyzed with SEM and XRD. P110 displayed the highest corrosion rates (15.7 mm/y at 10 hours, 2.9 mm/y at 100 hours) but developed a thick FeCO3 layer after 100 hours. In contrast, P91 and SS 316 exhibited lower corrosion rates after 100 hours (0.04 mm/y and < 0.01 mm/y, respectively). The influence of Cr content and exposure duration on the corrosion behavior of these steels were discussed. All steels exhibited decreasing corrosion rates over time, primarily due to oxide formation, enhancing the understanding of casing and tubing steel corrosion in s-CO2 environments.

Evaluation of Coatings to Improve Steel Compatibility in Supercritical CO2

Product Number: 51323-19207-SG

Author: B. A. Pint, R. Pillai, J. R. Keiser

Publication Date: 2023

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.
