Air Pollution Control

Aging 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.

Sturtevant’s Solution: Sturtevant® FGT Series Technology

The Simpactor® FGT Series and Powderizer® FGT Series effectively reduce sorbent particle size improving the emissions of coal fired power plants, industrial boilers, municipal furnaces and bio-mass plants.

The FGT Series Mills, decrease operating and disposal costs through decreased sorbent usage and provide utilities with an efficient and economical method for emissions control.
