Please advise on reduction of ammonia emissions from a fertiliser plant.
Our emissions from a urea plant stack is about 150 ppm, and we need to reduce them to 50 pp to comply with EPA regulations. I know some plants are provided with an acid washing system.
I would be grateful for advice from anyone with experience in this field.

I would expect that a simple water wash will do the job. No need to acidify the water. This will lead to problems with corrosion. A simple water wash will give you water with NH3 which you can strip in a steam stripper.
I am no specialist on fertiliser plants, but more used to refineries.
A water wash will likely reduce the emissions to a few ppm.......
