Abstract Sulfur dioxide (SO2) and nitrogen monoxide (NO) are some of the gas impurities present in the carbon dioxide (CO2) 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 analyse the risks in case of geological storage. The enthalpies of solution of SO2 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 vapour-liquid equilibrium.

二氧化硫和一氧化氮在水中的溶解

摘要 二氧化硫 (SO2) 和一氧化氮 (NO) 是使用燃烧后捕获过程从烟气中分离出的二氧化碳 (CO2) 中存在的一些气体杂质。即使是少量，这些杂质也可能对存储过程的发展产生影响。此类气体在水相中的溶解是为开发工艺和分析地质储存风险而进行的研究的一部分。SO2 和 NO 在水中的溶液焓在这里通过量热法研究，使用流动量热技术。二氧化硫的溶液焓分别为 323.15 K 和 373.15 K，一氧化氮为 323.15 K。实验焓数据与可用的溶解度数据一起用于测试代表气液平衡的热力学模型。
