NOx Control Systems

SCR and SNCR systems are common technologies used for NOx Control

Secondary Emission Control Technology used in Power Plants and Utilities to control emissions of Nitrogen Oxides (NOx) can be Selective Non Catalytic Reduction (SNCR) or Selective Catalytic Reduction (SCR). SNCR and SCR systems are both common technologies used for NOx control. However, it is not an easy choice to know which one to choose.

Reducing your NOx Emissions

As a World leader in Ammonia and SNCR, Yara offers its clients one of the most comprehensive and effective solutions to reduce NOx emissions in industrial power plants and utilities. From new builds, or upgrades to optimization of your current NOx control system, we can work with you to help reduce your NOx emissions.

Stationary plants

SNCR systems

Yara’s SNCR Technology can reduce your NOx emissions by up to 95%. SNCR is the cost efficient NOx reduction system.

Stationary plants

SCR systems

SCR Technology can achieve more than 95% NOx reduction. SCR is the absolute NOx control system.

Hybrid SNCR and SCR Systems

Hybrid SNCR/SCR Systems for NOx reduction

Hybrids are the optimal choice where the need for NOx reduction is high but space limitations are present. Hybrid systems are the most flexible choice of reducing NOx emissions.
