The solubility of weak electrolyte gases such as ammonia, carbon dioxide, sulfur dioxide, or hydrogen cyanide must be known for process design in many applications. Typical examples are applications in the chemical and oil-related industries, the production of fertilizers, and applications in environmental protection. Correlating and predicting the simultaneous solubility of ammonia and sour gases in aqueous phases are difficult tasks due to chemical reactions in the liquid phase resulting in the presence of ionic species. Furthermore, the liquid phase often contains other strong electrolytes, and solid phases might precipitate. The simultaneous solubility of ammonia and carbon dioxide in aqueous solutions of sodium sulfate was measured in the temperature range 313--393 K at total pressures up to 3 MPa. Experimental results are reported and compared to correlations and predictions. Predicted results generally agree well with experimental data.
