Air Pollution Control

Efficient and Economical Emission Control

Sturtevant Air Pollution ControlAging U.S.coal fired power plants and industrial boilers need to reduce SO2, SO3, Hg and HCl emissions to meet new regulations in Air Pollution Control. Most plants opt for Flue Gas Treatment (FGT) or Flue Gas Desulfurization (FGD) using a Dry Sorbent Injection system (DSI) with fine Trona (Sodium Sesquicarbonate) or Sodium Bicarbonate as a sorbent.

Reducing particle size increases sorbent surface area and reduces the amount of sorbent required. Dry sorbents are typically delivered to power plants unmilled. Testing has proven that the reactivity of sorbents can increase exponentially when sorbent particle sizes are reduced. The best way to increase surface area is to mechanically reduce the particle size by milling the sorbent.

The Simpactor FGT Series effectively  improves the emissions of coal fired power plants, industrial boilers, municipal furnaces and bio-mass plants by reducing the particle size of sorbents such as:

  • Trona
  • Sodium Bicarbonate
  • Hydrated Lime

Sturtevant’s Solution: Simpactor FGT Series Technology
