Hybrid technology can be a cost-effective compromise for exhaust gas treatment with the SNCR and SCR system, reducing NOx and balancing capital and operating costs.
New nitrogen oxide (NOx) control hybrid systems, using a combination of selective non-catalytic reduction (SNCR) and selective catalytic reduction (SCR) technology, have been developed which offer the best of both systems.
In applications where a high NOx removal is required, space is limited and low CAPEX is required, a hybrid solution can be the optimal choice as the catalyst volumes can be reduced compared with a full SCR system.
These hybrid systems reduce the level of NOx in fossil fuel combustion flue gas with a SNCR treatment stage followed by a SCR treatment stage. This reduces the size of the catalyst required, reduces investment and minimizes volume issues on site.
You can rely on the expertise and experience of Yara Environmental Technologies, a world leader in SNCR and SCR systems, with over 1,500 installations of these types of technology around the world.
If you need it, we can design a tailor-made hybrid system to suit your particular site and requirements. We have installed hybrid systems at client sites and have the expertise needed.
When choosing hybrid SCR/SNCR technology you also need to choose a reliable reagent supplier for ammonia or urea. Yara can assure you of quality and reliability of supply.
Yara hybrid SCR/SNCR systems are built to operate and perform in tough industry environments. Our robust systems operate as specified and with minimal interruption.
To help you optimize uptime and to prevent disruptions from unexpected shutdowns due to normal wear and tear of components, you can choose an agreed Maintenance Service package.
To ensure efficiency for you, we keep a stock of standard spare parts and consumables for your hybrid system. Ordering direct from Yara ensures you receive the correct component, compatible with your hybrid SNCR/SCR system, delivered rapidly.
You can also opt for a spare part package, which contains the expected yearly consumption of "normal wear and tear" components, ensuring even faster and easier access to your necessary parts.
We can offer design, build and upgrade of storage solutions to fit your NOx reduction reagents needs. This can be as part of your hybrid SNCR/SCR installation, or as a stand-alone storage tank solution.
You can also get an optimization assessment of your current reagent usage, as part of our service offer. If your reagent situation changes, we can recommend and deliver, standardized or customized, NOx reduction reagent storage solutions, and internal site distribution solutions, to your NOx control installations.
