Convective stability analysis of the long-term storage of carbon dioxide in deep saline aquifers
Deep saline aquifers are one of the most suitable geologic formations for carbon sequestration. The linear and global stability analysis of the time-dependent density-driven convection in deep saline aquifers is presented for long-term storage of carbon dioxide (CO2). The convective mixing that can greatly accelerate the CO2 dissolution into saline aquifers arises because the density of brine i...
متن کاملHydraulic controls on injection of carbon dioxide into deep saline aquifers
Sequestration of carbon dioxide in geologic formations, both deep aquifers and depleted petroleum reservoirs, has the potential to signi...cantly reduce the atmospheric emissions of that greenhouse gas. Injection into a deep saline formation di¤ers from injection into a hydrocarbon reservoir in that there is no produced ‡uid from the aquifer and the hydrogeologic characterization of both the re...
متن کاملDesign of carbon dioxide storage in aquifers
We propose a carbon storage strategy where CO2 and brine are injected into an aquifer together followed by brine injection alone. This renders 80–95% of the CO2 immobile in porescale (10 s mm) droplets in the porous rock. Over thousands to billions of years the CO2 may dissolve or precipitate as carbonate, but it will not migrate upwards and so is effectively sequestered. The CO2 is trapped dur...
متن کاملPrediction of Solubility of β-Carotene as a Component in a Multicomponent System in High-Pressure Carbon Dioxide
Solubility prediction of high molecular weight molecules in high-pressure solvents is an interesting field of research. Sometimes the solubility data are not available for several components due to lacking of valid equipments. Therefore, an accurate prediction technique can help the researchers. According to the literature, the simple Equations of State (EoSs) such as Soave-Redlich-Kwong (SRK),...
متن کاملImpact of pressure, salt concentration, and temperature on the convective dissolution of carbon dioxide in aqueous solutions.
The convective dissolution of carbon dioxide (CO2) in salted water is theoretically studied to determine how parameters such as CO2 pressure, salt concentration, and temperature impact the short-time characteristics of the buoyancy-driven instability. On the basis of a parameter-free dimensionless model, we perform a linear stability analysis of the time-dependent concentration profiles of CO2 ...
