“…In these cases, mineral proxies are often used to approximate rate parameters. Selection of an appropriate mineral proxy is not trivial as the resulting approximations can significantly impact predicted mineral reactions . Microstructural details, such as the distribution of Al/Si ordering in feldspars, are often not accounted for and may considerably influence mineral reactivity …”

Carbon capture and storage (CCS) is likely to be a critical technology to achieve large reductions in global carbon emissions over the next century. Research on the subsurface storage of CO2 is aimed at reducing uncertainties in the efficacy of CO2 storage in sedimentary rock formations. Three key parameters that have a nanoscale basis and that contribute uncertainty to predictions of CO2 trapping are the vertical permeability kv of seals, the residual CO2 saturation Sg,r in reservoir rocks, and the reactive surface area ar of silicate minerals. This review summarizes recent progress and identifies outstanding research needs in these areas. Available data suggest that the permeability of shale and mudstone seals is heavily dependent on clay fraction and can be extremely low even in the presence of fractures. Investigations of residual CO2 trapping indicate that CO2-induced alteration in the wettability of mineral surfaces may significantly influence Sg,r. Ultimately, the rate and extent of CO2 conversion to mineral phases are uncertain due to a poor understanding of the kinetics of slow reactions between minerals and fluids. Rapidly improving characterization techniques using X-rays and neutrons, and computing capability for simulating chemical interactions, provide promise for important advances.

“…The dissolution/transition among the carbonate minerals and the incongruent hydrolysis of aluminosilicates, mainly feldspars, to clays have been well documented in other CO 2 -water-rock reaction studies (Kaszuba et al, 2013;Lu et al, 2013;Wigand et al, 2008). In the Wekerdam gas field, the mineralogical study concluded that feldspar hydrolysis promoted the transformation of kaolinite to illite, whereas dolomite and siderite are the main carbonate precipitates (Koenen et al, 2013). When sandstone samples from the Songliao Basin in China were subjected to laboratory experiments simulating reservoir conditions (T=100 o C, P=24MPa), complete dissolution of calcite and partial hydrolysis of feldspars occurred, together with enrichment in quartz and clays (Yu et al, 2012).…”

“…The predicted geochemical reactions were compared to paragenetic sequences observed in sandstones from existing oil and gas fields. In the Werkendam gas field (Netherlands), the mineralogical assemblage consists of kaolinite which reacted with Kfeldspar to form illite and quartz, whereas dolomite and siderite are the main carbonates (Koenen et al, 2013). CO 2 has been accumulating in Montmiral Triassic Sandstone since 15 Ma ago, leading to the formation of kaolinite at the expense of K-feldspar, corrosion of ankerite and precipitation of barite, and ankerite/dolomite phases as secondary products.…”

Representative sandstone samples from Mesohellenic Trough (NW Greece) were selected to investigate the geochemical reactions that occur when they come in contact with CO 2 under representative in-situ conditions (T=70 o C, P=150bar, 6 months reaction in batch experiments). Those sandstones consisted of predominant calcite and quartz, with lesser amounts of feldspars, chlorite, ankerite, dolomite, kaolinite, montmorillonite and muscovite. After reaction with CO 2 , the brine became acidic and was enriched in cations as a result of mineral dissolution. Minor mineralogical changes were observed that involved: a) the dissolution of carbonate minerals and b) the incongruent dissolution of chlorite to form clays and silica. The results related to these, have been linked with geochemical modelling using the PHREEQC code. Simulation results for a 10 ka time period predicted that chlorite was expected to dissolve completely within 100 years, leading to boehmite growth and increasing the mass of dolomite. Feldspars were expected to react at a later stage in the reaction sequence. Sensitivity tests were run to access the effect of various adjustable parameters on the outcome results. The geochemical experiments and modelling lend support to the view that Pentalofos and Tsotyli sandstone formations of the Mesohellenic Trough are suitable for the long-term storage of CO 2 produced in the neighbouring lignite-fired power plants, at least in terms of mineralogy and geochemistry.

“…PHREEQC geochemical modeling was able to simulate the observations of mineral reactions induced by carbonized brine, at Werkendam and Barendrecht-Ziedewij gas fields, CO 2 -and CH 4 -bearing stratigraphic equivalents in the Netherlands [107]. The results showed that the difference in paragenetic sequence between the two fields was partially due to different temperature evolutions and fluid influxes.…”

Mineralization of Carbon Dioxide: A Literature Review

et al. 2015

View full text Add to dashboard Cite

Research on carbon capture and storage has been focused on CO 2 storage in geologic formations, with many potential risks. An alternative to conventional geologic storage is carbon mineralization, where CO 2 is reacted with metal cations to form carbonate minerals. Mineralization methods can be broadly divided into two categories: in situ and ex situ. In situ mineralization, or mineral trapping, is a component of underground geologic sequestration, in which a portion of the injected CO 2 reacts with alkaline rock present in the target formation to form solid carbonate species. In ex situ mineralization, the carbonation reaction occurs above ground, within a separate reactor or industrial process. This literature review is meant to provide an update on the current status of research on CO 2 mineralization.
