What is the concentration of ammonia solution?
Thread Content
What is the maximum concentration limit for ammonia solution? Can 23% be achieved? What is the basis for this? Please tell me, Brother **
I would appreciate it if everyone could share their insights; thank you in advance
It is related to temperature and pressure. At normal temperature and pressure, the solubility of ammonia can reach 0.5 g NH3/g H2O

At an absolute pressure of 1 kg/cm2, the saturation depth of ammonia water at 20 degrees is 33.95%； Information on the concentration of ammonia water at other pressures and temperatures can be found at the following link: http://bbs.hcbbs.com/viewthread.php?tid=391626&highlight=%B0%B1%CB%AE Fourth floor
A concentration of 23% ammonia can be achieved. Typically, a packed tower is used to absorb gaseous ammonia; in the case of atmospheric pressure processes, ordinary circulating water is used for cooling, and a concentration of 25% can be easily attained. If the pressure is controlled at 0.1–0.2 Mpa, a concentration of around 28% can also be achieved.
Don’t worry~~ I’ve seen it at 27 degrees at least
