An industrial power plant at dusk showcasing Marsulex Environmental Technologies' AS WFGD system that converts SO2 into eco-friendly fertilizer, enhancing sustainability.

Ammonia-based FGD and ammonium sulfate

Capture SO₂ with ammonia and convert it into ammonium sulfate fertilizer.

Advantages of AS WFGD System

  • Ammonia reagent more reactive than limestone and capable of achieving > 98% SO₂ removal efficiency
  • AS FGD produces high value by-product versus low value gypsum or sulfite waste sludge
  • Designed with standard conventional critical equipment redundancy
  • AS water soluble chemistry prevents any internal build-up versus scaling potential with limestone scrubbing
  • Lower overall operating cost through elimination of waste product disposal and high value by-product production.
Spilled granules of ammonium sulfate, a byproduct of the eco-efficient WFGD process, representing a sustainable solution in reducing emissions without producing CO2.

Benefits of Ammonium Sulfate WFGD

  • Economics enhanced with low cost, high sulfur fuels
  • Reduces / eliminates solid and liquid waste disposal requirements / costs
  • Valuable AS fertilizer provides revenue stream
  • No CO₂ greenhouse gas is produced in the AS WFGD process (unlike limestone/lime WFGD)

Commercially Proven Technology

  • Over 25 years of commercial operation at Dakota Gasification, 350MW
  • Over 15 years of commercial operation at Canadian Petrochem facility, 315 MW
  • Over 10 years of commercial operation at Yanzhi Petrochemical Company Thermal Plant, 2 x 100MW
