Get advice and expertise

We can help if you are:

  • Building or installing a new DeNOx system.
  • Upgrading a DeNOx system.
  • Optimizing an existing DeNOx system.

Get advice and expertise to help you optimize your consumption of NOx control reagents to ensure maximum performance without over-injection, thus reducing your reagent costs.

Our SCR (Selective Catalytic Reduction) and SNCR (Selective Non Catalytic Reduction) systems are developed with this in mind. You can rely on Yara to fully understand your business and your needs as we are a leader in ammonia, urea, SCR and SNCR technology. This makes us the NOx control partner you are looking for. 

Choice of systems for exhaust gas treatment

Hybrid SNCR/SCR – systems a cost-effective compromise
Hybrid technology can be a cost effective compromise with the SNCR and SCR system reducing NOx, balancing capital and operating costs.

The reagents you need

Anhydrous Ammonia
Anhydrous Ammonia
Anhydrous Ammonia has advantages over ammonia solution and urea when lower NOx emissions are required.
Ammonia solution
Ammonia Solution
Ammonia Solution is safer to use than anhydrous ammonia so is it is an efficient reagent and good compromise for NOx treatment.
Urea solution
Urea Solution
Urea is often the reagent choice for safety reasons and easy transportation, but it can be less efficient.
