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.

Corrosion Resistance Evaluation Of Super Duplex Stainless Steel In Supercritical CO2 Saturated Liquid Phase Containing Impurities O2 Or SO2

Carbon capture, utilization and storage (CCUS) is one of the key technologies to achieve the net-zero emission. One of the CCUS method is CO₂ injection to depleted oil and gas wells or aquifers and storage (CCS). The CO₂ emitted from fossil fuel-based powers and industrial plants are captured and transported to the injection point by ships or pipe line. Following that, the dense phase or supercritical phase CO₂ will be injected to depleted oil and gas wells or aquifers through oil country tubular goods, for examples, seamless pipe.

In carbon dioxide capture and storage, CO2 emitted from various industries containing impurities is captured and injected underground in dense or supercritical phase through tubings. In order to evaluate corrosion resistances of materials in the supercritical CO2 with a slight amount of O2, corrosion tests were performed under the conditions of 5 mass% NaCl equilibrium with CO2, containing with the various amount of O2 at total pressure of 130 bar and 100 °C. Super Martensitic Stainless Steel (UNS S41426), Duplex Stainless Steel (UNS S82551), and Super Duplex Stainless Steel (UNS S39274) were evaluated. Localized corrosion was observed in S41426 at conditions higher than 200ppm O2 (0.026 bar O2 partial pressure) condition. On the other hand, S82551 and S39274 showed good corrosion resistance in the same condition. As for S82551, it suffered from localized corrosion at 1000ppm O2 (0.13 bar O2) condition. However, in the actual O2 concentrations, it is considered that S82551 and S39274 are suitable materials even if formation water flow back has occurred.

Corrosion testing of CRA in simulated CO2 injection well environments

Product Number: 51323-18993-SG

The number of CCS projects (planned and in operation) is increasing, and project developers need to provide firm evidence that the proposed material is suitable for these applications.
The petroleum industry has long experience with materials selection for wells, but the conditions for CO2 injection wells are somewhat different from “conventional” oil and gas wells. This is due to the high CO2 content and pressure (up to several hundred bar) which results in low pH condensed water (exact value depends on pressure and temperature, but approximately pH 3.0).

High pressure and high temperature processes are present in a wide variety of industries and are often pushing the limits of common materials. As a result, these applications have required advanced materials as well as an improved understanding of the in-situ conditions. Furthermore, those processes have become more and more present in a wide range of industries such as upstream oil and gas (O&G) and power generation (in supercritical CO₂ or molten salt nuclear reactors). The corrosion performance of existing and emerging materials to the extreme environments present in next generation power must be well characterized to ensure material integrity and reduce the risk of catastrophic failures due to environmentally assisted cracking, homogeneous corrosion, thermal oxidation, or other mechanisms.
