Could some kind person tell me the approximate composition of the exhaust gases from phosphoric acid ammonium production?

I’m working on the design of a device for treating phosphoric ammonium exhaust gases; could everyone give me some help?
The main components are fluorine, ammonia, water vapor, and phosphorus pentoxide; a Venturi-jet type empty tower can be used.
It can be treated through two stages of washing. The first stage involves acid washing, which helps to reduce the ammonia content in the exhaust gases while minimizing ammonia loss. The second stage uses water washing to remove fluorine from the exhaust gases. Ammonium phosphorus exhaust gases mainly consist of water vapor, fluorine, carbon dioxide, ammonia, and other substances
