Influence of NH4Cl, NH4NO3, and NaNO3 on the simultaneous solubility of ammonia and carbon dioxide in water

New experimental results for the simultaneous solubility of ammonia and car bon dioxide in (about 4 m) aqueous solutions of NH4Cl, NH4NO3, and NaNO3 at (313, 353, and 393) K and total pressures up to about 0.7 MPa are reported . The maximum loading of carbon dioxide to ammonia, i.e., the molar ratio o f carbon dioxide to ammonia, in the liquid phase was about 1 (at 313 K), ab out 0.7 (at 353 K), and about 0.3 (at 393 K). The experimental results are used to assess predictions from a thermodynamic model for the solubility of ammonia and sour gases in aqueous solutions of strong electrolytes.
