Climate change and global warming are among the major environmental challenges associated to increased global carbon dioxide emissions. furthermore, the world in general and he Gulf region in particular suffer from scarcity of clean water sources. Therefore, this research focuses on addressing these two crucial problems by applying mineralization process. CaO and MgO are among the divalent cations that contribute significantly for carbonation process. The carbonation reaction between CO, MgO, and CaO produces carbonate minerals such as calcium carbonate(CaCO3) and magnesium carbonate (MgCO3). Hence, brine coming out of a reverse osmosis unit as reject containing significant amount of Ca and Mg ions can be used for this application. In this study the effect of brine concentration, contact time, temperature and pressure on CO2 mineralization by brine has been investigated. The results of the experiments showed that the carbon dioxide mineralization rate depends mainly on three factors, which are temperature, concentration and time, and does not depend mainly on pressure. Through the experiment, it became clear that the optimal conditions for the occurrence of the mineralization process are when the temperature is 70 °C and the experimental time is 3 hours. The effect of carbon dioxide mineralization on Resistance, Capacitance, Impedance, pH, EC, Index (Brix) and Salinity were also studied.
