NO solubility in water and brine up to 60 MPa and 373 K by combining Raman spectroscopy and molecular simulation

In the processes of carbon capture and storage, sulfur nitrogen oxides (SOx NOx) would be possibly injected with CO2 depending on origin CO2. The thermodynamic properties these gases in saline aquifer are poorly known. Solubility is one key parameter to implemented geochemical codes modelling long-term evolution after injection. solubility NO known only at atmospheric pressure. this study, water NaCl solutions was measured by Raman spectroscopy ranges 295–373 K 2–60 MPa using a high pressure optical cell calibration few data from molecular simulations. results show decrease when temperature increases salinity increases. No modification speciation observed.
