Thanks for the replies. Since now I have known that no matter how I boil the ammonia water to desorb ammonia, water will always present. And since there is people that wanted me to elaborate my question, here it goes.
I am doing a Fluent simulation of boiling 20% ammonia water under 4 atm using multiphase model. The issue is I need to define the mass transfer from liquid phase to vapor phase, and the mass transfer model I plan to use is evaporating-condensation. However, to use this evaporation-condensation model, I will need the saturation temperature. As far as I know, the saturation temperature is used to define the further dissolving of ammonia. However, since a small fraction of water will be vaporized as well, how do I determine the temperature for the water to start vaporizing (can I use the boiling point of water under 4 atm)?
Thanks in advance.
