Solubility of CO2 in aqueous ammonia solution at low temperature

The solubility of carbon dioxide in aqueous ammonia solution with concentrations of 1.13, 2.18, 3.83, 6, and 8.11 molal was measured at atmospheric pressure and a range of temperatures from 268.15 to 288.15 K. The results showed that the solubility of carbon dioxide in ammonia aqueous solution incre...

Description
Summary:The solubility of carbon dioxide in aqueous ammonia solution with concentrations of 1.13, 2.18, 3.83, 6, and 8.11 molal was measured at atmospheric pressure and a range of temperatures from 268.15 to 288.15 K. The results showed that the solubility of carbon dioxide in ammonia aqueous solution increased with increasing temperature. The UNIQUAC-NRF model is applied to the experimental data for the present work. This modified model is used to calculate carbon dioxide solubility in aqueous ammonia solution at a range of temperatures from 268.15 to 288.15 K and atmospheric pressure. The results of AAD% (Absolute Average Deviation) show that the UNIQUAC-NRF model can accurately correlate the solubility of experimental data of carbon dioxide in aqueous ammonia solution over a wide range of low temperatures.
