What is Ammonia Slip Catalyst ASC?
An Ammonia Slip Catalyst ASC is a crucial component in selective catalytic reduction SCR systems, specifically designed to mitigate the release of unreacted ammonia into the atmosphere. After ammonia is injected into exhaust gases to reduce nitrogen oxides NOx to nitrogen and water, some ammonia may bypass the main SCR catalyst. The ASC, positioned downstream, captures this excess ammonia, preventing its emission as an air pollutant. This secondary catalytic process oxidizes the slip ammonia into harmless nitrogen and water, ensuring the overall efficiency and environmental compliance of emission control systems in various applications, including diesel engines and industrial facilities.
