DRY SORBENT INJECTION (DSI) is an Air Quality Control technology utilized for regulatory compliant mitigation of sulfur dioxide, sulfur trioxide and hydrogen chloride | SO2, SO3, HCl | and for marginal pollutants | HF, Hg, PM10, PM2.5, H2S, H2SO4 | from power plants and industrial burners, such as cement and lime producers. 

Size reduction milling systems are at the heart of DSI Technologies. DSI performance is pronouncedly driven by the milled particle surface area of the sorbent material. The residence time of the milled sorbent material with pollutants (occurring within the flue-gas stream at a target temperature window) determines the level of pollutant capture and neutralization. By increasing the surface size of the sorbent, you are creating a greater contact area for adherence of toxins to the sorbent surface, and therefore achieving a higher pollutant capture value. Increasing surface sizing on a steep curve is the challenge for milling technologies. CMS DSI Systems meet that challenge.  

  • Proven performance (meets International Environmental Regulations)
  • Primary pollutant capture | SO2, SO3, HCl |
  • Marginal pollutant capture | HF, Hg, PM10, PM2.5, H2S, H2SO4 |
  • Low comparative capital cost
  • Easily integrates with existing Air Quality Control Systems and technologies
  • Reduced impact on ash handling/waste disposal
