Method of producing ammonia water by absorbing ammonia gas with clean water
Thread Content
I want to use clean water to absorb ammonia in order to produce 18% wt ammonia solution. Could anyone tell me the process involved, or where I can find relevant information? Thank you!
The absorption of ammonia gas by water is exothermic, and ammonia water at high temperature tends to release gaseous ammonia at room temperature. It is recommended to follow the following process for absorption: Desalinated water → Ammonia water circulation pump → Jet absorber (or bubble absorber tower) → Ammonia water cooler → Ammonia water storage tank → Ammonia water circulation pump → Product ammonia water. The amount of desalinated water added and the point at which the product ammonia water is discharged can be adjusted according to the pressure required for the product ammonia water. This forum has information on this topic; the original poster can give it a search. This post was last edited by mfjxg on 2009-2-6 15:14]
At normal temperature and pressure, the volume ratio of water to ammonia absorbed is 1:500; a concentration of 18% is required – is pressurization needed?
Is a packed tower not needed? Is pressure required to achieve this concentration?
