Ammonium Nitrate Process Condensate - Reuse in Nitric Acid Production

On this and your othr post, I would suggest that a sketch of the process would be helpful to clarify what you are trying to do.

You must first adjust the pH of the process condensate to eliminate free ammonia before adding it to the nitric acid absorption tower. Adding ammonia to a nitric acid absorption tower can result in the formation of ammonium nitrite, which can carryover into the tailgas heater. Ammonium nitrite is very unstable.
