It works by funneling the ammonia laden exhaust stream through the bottom of a packed tower, which sprays a solution from specialized nozzles. This chemical solution is carefully chosen to react with the ammonia in the exhaust stream, and is very often a 93% Sulfuric Acid (H2SO4); this solution often achieves the best DRE, and keeps costs lower.
