Optimization of Dissolution of Ulexite Mineral at High Temperature in Aqueous and Borax Pentahydrate Solutions Saturated with Carbon Dioxide

Impact 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 ...

Enhancing serpentine dissolution kinetics for mineral carbon dioxide sequestration

Mineral carbon dioxide sequestration binds carbon dioxide by reacting it with magnesium silicate minerals to form solid magnesium carbonates that are ready for disposal. Research onmineral sequestration has focused on enhancing process kinetics in aqueous processing schemes. High costs of these processes are associatedwithmineral processing, such as ultrafine grinding, or the consumption of aci...
