Résumé

Solubility measurements in conditions relevant to CO2 geological storage are sparse, especially solubility data of water in the CO2-rich phase. New data are acquired by in situ Raman spectroscopy in NaCl aqueous. An effect of NaCl concentration is observed on calibration curves in the H2O-rich phase: the slope of the fitted curve ICO2/IH2O = f(sCO2) is equal to 4.97, 4.25, and 3.93 at 0, 1, and 2 M NaCl, respectively. On the contrary, the Raman signal in the CO2-rich phase is not affected by salinity. The slope of the fitted curve ACO2/AH2O = f(yCO2/yH2O) is equal to 1.72 whatever the NaCl concentration.
