Redecam offers the most effective ways of reducing nitric oxide and/or nitrogen dioxide (NOX) in raw gas emissions: with Selective Catalytic Reduction (SCR), Selective Non-Catalytic Reduction (SNCR) and Hybrid SNCR/SCR Systems.
We can help you evaluate which system is best for your needs considering your combustion process, operating parameters, NOX flue gas levels, emission reduction targets and CAPEX and OPEX availability. Based on this process data, our experts can design, build and install a customized NOX reduction solution.
Selective Catalytic Reduction (SCR)
Selective Catalytic Reduction (SCR) is the optimal NOX control system, able to achieve more than 95% NOX reduction in combustion processes. It can therefore meet stricter incoming legislation.
- Optimum effectiveness, reducing NOX by 95%;
- Meets stricter incoming legislation;
- Not as sensitive to varying temperatures as SNCR;
- Perfect mixing is not required, as in SNCR;
- Commissioning can be done during plant’s annual downtime.
Selective Non-Catalytic Reduction (SNCR)
Selective Non-Catalytic Reduction (SNCR) can easily reduce the NOX emissions by more than 80%, and in some cases even up to 95%. It is a cost-effective method of reducing NOX. It can often be installed without plant downtime.
SNCR is a method to reduce nitrogen oxide emissions in conventional power plants that burn biomass, waste and coal as well as in cement plants, waste incinerators and waste-to-energy plants.
- Cost-effective in terms of CAPEX;
- Faster installation, often with no plant downtime required;
- Up to 95% effective;
- Low maintenance, as there is no catalyst to replace and the system is fully automated.
Hybrid SNCR/SCR Systems
Hybrids are a newer technology, often an ideal choice when high NOX reduction is required and when space is limited. They are the most flexible choice to reduce NOX emissions.
Hybrid systems reduce the level of nitrogen oxides (NOX) in fossil fuel combustion flue gas with a Selective Non-Catalytic Reduction (SNCR) treatment stage followed by a Selective Catalytic Reduction (SCR) treatment stage. Hybrid systems are tailored to your needs: the percentage of the system acting as SNCR and the percentage acting as SCR vary depending on the process data of your facility.
- Can be lower in terms of CAPEX;
- Lower operating costs than SCR technology;
- Ideal when a high NOX removal is required;
- Requires limited space;
- Less catalyst required than with SCR system.
