NOx Reduction in Industrial Plants

As a NOx abatement technology leader, Yara continues to develop its nitrogen oxide air pollution reduction technology capacity to keep ahead of incoming legislation. Through strategic acquisitions and investments, Yara is a leading provider of the two main NOx after-treatment technologies, Selective Catalytic Reduction (SCR) and Selective Non-Catalytic Reduction (SNCR), along with the reagents required to reduce NOx emissions.

Read how we can help you reduce your NOx emissions by up to 98% with our SCR, SNCR and Hybrid technologies.

SNCR/SCR Hybrid systems for NOx reduction

Hybrid systems reduce the level of NOx (nitrogen oxides) in the flue gas with a hydrocarbon treatment in 2 stages: selective non-catalytic reduction (SNCR), followed by selective catalytic reduction (SCR).

Why choose a Hybrid SNCR/SCR system?

A hybrid system may be an interesting alternative versus installing a single SCR system. Hybrid systems help to find a balance between investment costs (CAPEX) and operating costs (OPEX). This is particularly useful for cases where:

  • A significant reduction in NOx emissions is expected, yet flexibility of operation is needed
  • The installation space available for the catalyst is restricted
  • Increasing the pressure drop is critical or leads to higher operational costs and significant investments

In such cases, the hybrid solution is the best choice : it reduces the size of the catalyst to be installed, thus reducing investment, and volume issues at the site.
