Energy from Waste (EfW) facilities play a crucial role in managing residual waste and generating energy, but they must also operate within strict environmental standards. One of the most significant challenges is the control of nitrogen oxides (NOx) – harmful gases produced during combustion that contribute to air pollution and acid rain.

To meet emissions regulations, many EfW plants adopt Selective Catalytic Reduction (SCR) or Selective Non-Catalytic Reduction (SNCR) systems. These technologies rely on reagents such as aqueous ammonia to effectively reduce NOx levels before gases are released into the atmosphere.

How Aqueous Ammonia works in NOx Abatement

In NOx abatement, aqueous ammonia is injected into the flue gas stream at controlled temperatures. The ammonia reacts with nitrogen oxides, converting them into harmless nitrogen and water vapour. This simple yet effective chemical reaction significantly reduces NOx emissions, ensuring compliance with environmental legislation and supporting cleaner air initiatives.

Using aqueous ammonia instead of alternatives like urea provides advantages in terms of reactivity, efficiency, and operational flexibility. For EfW operators, this means greater control over emissions and the ability to fine-tune processes for optimal performance.
