SNCR (Selective Non-Catalytic Reduction) is a method to reduce the level of NOx (nitrogen oxides) emissions in conventional combustion plants that burn coal, biomass and waste. Cement plants, waste incinerators and waste-to-energy plants that need to reduce their NOx emissions will often choose SNCR as an efficient, low-cost NOx reduction system. If optimum process conditions can be found in the host process, Yara’s SNCR technology can easily reduce the NOx emissions by more than 80%, and in some cases even upto 95%.
Why choose Selective Non-Catalytic Reduction?
Selective Non-Catalytic Reduction (SNCR) involves only a fraction of the investment cost compared to SCR technology. It can, in many cases, also be installed without the need of expensive downtime which is required for installing catalyst, injection grids and mixers required for SCR.
Yara’s high performance SNCR systems, developed by an expert NOx control team at Yara Environmental Technologies, (formerly known as Petro Miljö SNCR systems), have been installed at more than 200 facilities worldwide.
Petro Miljö, now known as Yara Environmental Technologies, is a world leader for the build and installation of SNCR systems.
Yara Environmental Technologies, team of experts has a wide knowledge of client processes in cement plants, waste incinerators, waste-to-energy and biomass plants that need to have NOx control. Yara’s SNCR system is based on high performance assembled modules which can be tailor-made to ensure your NOx control processes meet your legislation needs. We deliver new, complete systems based on standard or customized modules, or Yara can work with you to optimize, modify or expand your existing SNCR system to fit your purposes.
Pre-emptive maintenance services
Yara SNCR systems are built to operate and perform in tough industry environments. Our robust systems operate as specified and with minimal interruption.
However, to optimise uptime, and prevent normal wear and tear of components disrupting your processes through unexpected shutdowns, we offer our SNCR customers a Pre-emptive Maintenance Service package.
