Product Inquiry
DAS EE‘s Catalytic Systems represent an advanced solution for the semiconductor industry, offering superior performance in exhaust aftertreatment by harnessing the power of Selective Catalytic Reduction (SCR) with ammonia for DeNOx and fine dust removal through a highly effective membrane filter. The Catalytic System ensures exceptional reduction efficiency with minimal energy consumption by recovery of more than 80% of the process heat. With the advanced, reliable, and environmentally friendly solution, you can stay ahead of environmental regulations and achieve your sustainability goals.

Functioning principle of the Selective Catalytic Reduction and Membrane Filter

DeNOx: SCR (Selective Catalytic Reduction) with Ammonia

  • High reduction efficiency regardless NOx source: up to 95% *
  • Low NH3 slip: 10 ppm by precise control of the dosed reducing agent *
  • Flexible solution for NO and NO2 in broad concentration ranges up to 4000 ppm at total volume flow of up to 5000 slm
  • Low energy demand: low temperature process and energy recovery by heat exchanger

DeDust: Membrane Filter (Surface Filtration)

  • Necessary pre-treatment for catalyst
  • High reduction efficiency of PM2.5, PM10, total dust fraction (up to 99.9%)
  • Applicable for typical post-combustion PM pollutants

* Tradeoff between NOx DRE and NH3 slip: Increase of DRE will result in increase of slip and vice versa.
