Preliminary investigation on the likelihood of trapping CO2 and NH3, which are emitted at a rate of 132 mg/h and up to 5.1 – 510 mg/h during the storage of manure at 25 °C, in brines of NaCl and CaCl2 was conducted in Aspen Plus® v12. The supersaturated solution of 0.5 kg H2O and 10 kg salt was considered to account for any possible absorption in the liquid film that is generated during the deliquescence phenomenon. Only in the case of using the CaCl2 as dehydrating agent (anhydrous salt) in the prototype, the simulation in the commercial package predicted the absorption of CO2 and NH3 and formation of CaCO3 and NH4Cl. On the other hand, the extents of formation of NaHCO3, and even NH4HCO3 or NH4COONH2 were found to be negligible under the conditions that the prototype operates. Prediction of the solubilities of NaCl, NH4Cl, NaHCO3, CaCO3, Ca(OH)2, CaCl2, CaCl2·H2O, CaCl2·2H2O, CaCl2·4H2O, and CaCl2·6H2O in the temperature range 0 – 100 °C at 1 atm.
