We have a fish factory that has asked for NH3 scrubbers for all their ventilation, because they are close to a populated area.

They have had a blowout (faulty service valve that wouldn't close), and it caused a massive evacuation.

I've read about ammonia scrubbers, where there is a water/sulfuric acid mix that is circulated as a mist and when ammonia gas comes in contact with this mix.

All the information I can find is for large industrial process plants, does anyone have any experience with this, or any more information?

Would be much appreciated
