EWK - Model KAT -Catalytic Gas Cleaning
Catalytic exhaust and exhaust air cleaning: EWK Umwelttechnik has been building systems for air pollution control and purification of exhaust gases for decades. The SCR (selective catalytic reduction) process is successfully used to reduce pollutants: Process exhaust, Combustion gases.

Modular design
- The reactor housing is made of stainless steel in a modular system with integrated insulation.
- This allows individual placement depending on the type of pollutant and concentration of pollutants.
- individual adaptation to structural conditions.
- compact and cost-effective design.
SCR catalyst technology is characterized by:
- low maintenance costs
- High operational reliability
- long service life
- simple operation
- Low operating costs
- good retrofitability for old plants
Advantages of using SCR technology with urea as a reaction agent
- Urea is non-toxic. Transport and storage are trouble-free
- NOx sales rates of over 98 are possible
- no or negligible reaction by-products
- low ammonia slip
- Incinerators
- Chemical, pharmaceutical industry
- Process exhaust
- Solvent disposal
- Stainless steel tining systems
- Gas, diesel engines
- Residual recycling plants
- Incinerators
- Glass tubs
- Combined heat and power plants
- Explosives dissolocation
Both the combustion of biofuels as well as fossil fuels and industrial waste (solvent, sewage sludge, explosive, waste, industrial residues, etc.) also produce large quantities of
- Nitrogen oxide NOx
- Carbon monoxide CO
- Hydrocarbons CmHn
- Dioxins/furans
With the SCR catalyst technology, these high-efficiency air pollutants can be converted to N2,CO2 and H2O.
