Dürr Megtec spray dryer absorber (SDA) technology provides effective control of SOx and HCl by the injection of finely atomized alkaline slurries into the gas stream. Unlike wet scrubbers, all water is evaporated, with no liquid waste stream generated.

Our SDA technology is especially effective in municipal and solid waste incineration, power generation, cement, and metallurgical applications and offers the following benefits:

  • Dry operation
  • Greater than 90% removal efficiency
  • Opacity and secondary plume abatement

Dürr Megtec spray dryer absorber (SDA) technology provides effective control of SOx and HCl by the injection of finely atomized alkaline slurries into the gas stream. Unlike wet scrubbers, all water is evaporated, with no liquid waste stream generated.

Dürr Megtec SDAs utilize Turbotak atomizing nozzles to spray finely atomized alkaline slurries, such as calcium, sodium, or potassium-based slurries, into the gas stream. Contaminants are absorbed into the droplets, which quickly evaporate leaving the contaminants trapped in dry particles for collection by a downstream fabric filter or ESP.

Our SDAs are capable of simultaneously removing SO2 (90%) and HCl (>99%) with high efficiencies.
