SCDS PFC Abatement System

Pre-Packed Tower and Pre-Spray

• Water Scrubber
• Particulate Matter Removed
• Water Soluble (Acidic) Components Removed
• Pre-Packed Tower uses Re-Circulated Wastewater

Catalytic Reactor and Cooling Room

• Pre-heated mixing stage for PFCs/Air/Steam
• PFC cracking catalyst (PFCs-->CO₂ + HF
• CO oxidizing catalyst (Converts CO-->CO₂)
• Cooling room cools exit gases with water spray
• Cooling room uses re-circulated wastewater

Post Packed Tower

• Separates CO₂ and HF Gases
• Cyclone Dries CO₂ Gases
• Ejector (Venturi Pump) Removes CO₂
  From SCDS
• HF abosorbs into wastewater in
  post-packed tower
• Watewater collected and Re-Circulated by
• Wastewater tank
