Long-term fate of CO2 in a saline aquifer: modeling issues

Thermodynamic study of binary systems containing sulphur dioxide and nitric oxide: Measurements and modelling

“…Finally, all VL data were used to optimize settings of the PPR78 EoS. (9) and (10), and detailed in previous works [6,19,20,35]. The so-obtained critical coordinates, i.e.…”

“…The use of reactive-transport codes to investigate various scenarios is of upmost interest [10,11,12]. In most of the geochemical codes, chemical reactions and their equilibria are related to classical mass action laws, and water-gas equilibria are generally treated using a dissymmetrical approach γ-φ (i.e., activityfugacity) wherein the Henry constant (K H ) of gas species is a key property.…”

Effects of long-term flue gas exposure on chemical-structural properties of South African coals: perspective on advanced analytical techniques

“…The end course of the carbon sequestration technology in geological formations is to ensure safe and secure long-term CO2 storage as well as long-term stabilization of the storage site (Tcvetkov et al 2019). However, CO2 sequestration in unmineable coal seams is a complex occurrence due to the complex structure of coal; as a result, not many researchers have explored the long-term fate of CO2 through the various trapping mechanisms in the coal seams, its distribution within the coal matrix, and longterm site stabilization post-CO2 injection (Estublier et al 2014). In the framework of direct industrial flue gas injection in unmineable coal seams, there is currently no knowledge of long-term storage that has yet been reported in literature as well as the flue gas-coal long-term interaction under in-seam conditions of temperature and pressure.…”
