“…Using this technique, sample mass loss and evolved volatiles are monitored while a sample is subjected to a heating regime in a nominally inert atmosphere. Thermogravimetric approaches to mineral identification and quantification are well established, − and TGA–MS has been a trusted instrument for characterizing, identifying, and quantifying amorphous/crystalline carbonates. − TGA–MS instrumentation is especially suitable for analyses that require low levels of detection, ,− such as cases when multiple volatiles leave the sample at the same time–temperature and create otherwise inscrutable weight losses. Kemp et al pioneered the technique of quantifying carbonate content in basalt and related rocks with TGA–MS analyses and suggested a potential pathway to reach detection limits <100 ppm CO 2 using known concentrations of carbonate in inert corundum matrices, in line with a previous study of carbonate mineral detection via thermal analysis and coupled infrared spectroscopy evolved gas analysis .…”

Mitigating the deleterious effects of climate change requires the development and implementation of carbon capture and storage technologies. To expand the monitoring, verification, and reporting (MRV) capabilities of geologic carbon mineralization projects, we developed a thermogravimetric analysis−mass spectrometry (TGA−MS) methodology to enable quantification of <100 ppm calcite (CaCO 3 ) in complex samples. We extended TGA−MS calcite calibration curves to enable a higher measurement resolution and lower limits of quantification for evolved CO 2 from a calcite−corundum mixture. We demonstrated <100 ppm carbonate mineral quantification with TGA−MS for the first time, an outcome applicable across earth, environmental, and materials science fields. We applied this carbonate quantification method to a suite of Columbia River Basalt Group (CRBG) well cuttings recovered in 2009 from Pacific Northwest National Laboratory's Wallula #1 Well. Our execution of this new combined calcite and calcite−corundum calibration curve TGA−MS method on our CRBG sample suite indicated average carbonate contents of 0.050 wt % in flow interiors (caprocks) and 0.400 wt % in interflow zones (reservoirs) in the upper 1250 m of the Wallula #1 Well. By advancing our knowledge of continental flood basalt-hosted carbonates in the mafic subsurface and reaching new TGA−MS quantification limits for carbonate minerals, we expand MRV capabilities and support the commercial-scale deployment of carbon mineralization projects in the Pacific Northwest United States and beyond.

Commercial hot‐dip galvanized zinc (Zn‐0.2% Al), galfan (Zn‐5% Al), and galvalume (Zn‐55% Al) coatings were exposed to wet scCO2, followed by an assessment of microstructural changes in the coating structure. Zinc and galfan coatings showed similar surface activity with abundant zinc dissolution and uniform corrosion product deposition. The Al‐rich phases of the galfan coating were intact in the studied atmosphere and eventually became embedded within the deposits. The zinc dissolution ended for zinc and galfan coatings when the free metal surface was blocked from the surrounding medium by a uniform corrosion product layer. Galvalume showed scarce reactivity: dissolution of zinc in the Zn‐rich interdendritic areas proceeded slowly compared to zinc and galfan, and the Al‐rich dendrites (with nm‐scale Zn inclusions) remained intact. The ion beam milling technique combined with modern nm‐resolution energy‐dispersive spectroscopy analysis enabled previously unseen visualization of the discussed corrosion processes.

Supercritical CO2 (sc‐CO2) was widely used in CO2 flooding projects to enhance the recovery efficiency recently owing to its amazing dissolving capability and permeability. Fiber reinforced pipe (FRP) has exceptional properties that may be widely used in the petrochemical sector for transportation of corrosive fluid in CO2 flooding projects. In this research, a system was designed to simulate the transport behavior of fluids containing CO2 which can reaches the supercritical state by the adjustment of pressure and temperature. The fluid penetrates into the resin interior through the pores and gathers in the cavities at 65°C and 8 MPa. When the temperature and pressure are below the critical point, the CO2 volume expands dramatically, causing inter‐layered micro‐crack. When the environmental conditions repeatedly change above and below the critical point, these cracks will continue to propagate along the fiber arrangement direction, resulting in the fracture progressively grow into the delamination. At the same time, the fluid corrodes the resin in some areas of the surface, generating pitting and a 0.66% loss in resin content. The composition of elements and groups altered after corrosion revealed that a chemical interaction occurred between fluid and epoxy resin. Finally, due to physical and chemical processes produced by penetration, expansion, and dissolution, the stiffness of FRP fell by 3.53% during treatment.Highlights In the present work, a reactor coated with polytetrafluoroethylene (PTFE) was built to model the corrosion of FRP in delivery fluids containing sc‐CO2. The corrosion mechanism was shown as a combination action by chemical react and physical behavior comprising penetration, expansion and dissolution. The physical corrosion mechanism of fluid containing sc‐CO2 was investigated. The fluid containing sc‐CO2 penetrated the FRP via pores and accumulated in cavities. The quick expansion of sc‐CO2 causes delamination while the ambient circumstances remain below the critical threshold. The pitting and resin loss can be linked to the epoxy resin solution in supercritical CO2. The chemical process, known as hydrolysis, took place on the interior surface of epoxy resin and a fluid containing supercritical CO2. This finally resulted in molecular structural modification.
