Choose between SNCR and SCR when building a system to reduce NOx
Secondary measures to control emissions of nitrogen oxides (NOx) from plants can be done either with SNCR (selective non-catalytic reduction) or SCR (Selective Catalytic Reduction). SNCR and SCR are both technologies used for NOx control. However, choosing which solution is not always so easy.
If you need to reduce NOx emissions in an existing plant where there is currently no NOx control system installed, Yara can help you assess the best possible technique given your combustion process, the operating parameters of NOx levels in the flue chimneys and level of NOx reduction to be achieved.
Based on a technical evaluation of your facility and taking into consideration your CAPEX and OPEX, our experts can design, build and install SNCR, SCR or hybrid bespoke systems for you. We can also advise on the type of reducing agent to use.
As a global leader with more than 200 installations, Yara is the ideal partner to equip plants requiring SNCR or hybrid SNCR / SCR NOx control systems.
