Modeling of CO2 Solubility in Aqueous NaCl and Na2SO4 Solutions up to 473.15K and 20MPa

Summary The study of the phase equilibria of CO2 in aqueous solutions containing electrolytes is extremely relevant for several areas such as environment, oil and water production, or geothermal energy. With regard to the environment, CO2 capture and storage (CCS) in deep saline aquifers has been widely studied, as a strong potential for mitigating the global imbalance linked to greenhouse gas emissions. CO2 storage in deep aquifers is seen as the most promising geological storage techniques due to the large quantity and spreading of the reservoirs worldwide.
