| contents | Sulfur dioxide (SO$_2$) and nitrogen monoxide (NO) are some of the gas impurities present in the carbon dioxide (CO$_2$) separated from fume using post combustion capture process. Even in a small amount, these impurities may have an impact on storage process development. The dissolution of such gases in aqueous phase is part of the studies carried out to develop processes and analyze the risks in case of geological storage. The enthalpies of solution of SO$_2$ and NO in water were here investigated by calorimetry, using a flow calorimetric technique. The enthalpies of solution were determined at 323.15 K and 373.15 K for sulfur dioxide, and at 323.15 K for nitrogen monoxide. The experimental enthalpy data were used together with available solubility data to test thermodynamic models representative of vapor-liquid equilibrium. |
