Novel Integrated Desulfurization (NID*)

This system is made up of a patented integrated hydrator/mixer, a J-duct reactor, and typically a fabric filter. Hydrated lime is used as a reagent to react with gaseous pollutants like SOx, HCl, and HF. Mercury collection can be realized by injecting PAC upstream. The collected particles are then either recirculated or disposed.

• Our dry flue gas desulfurization systems have over 20 years of successful commercial operation, with more than 50 industrial references and over 15 GW installed globally 
• Up to 98% SO₂ removal, up to 4% sulfur in fuel, multi-pollutant control
• Compact footprint compared to Spray Dryer Absorber (SDA)
• Modular and standard design for lower construction costs 
• NID is a well-fitted technology for various industry applications, in particular waste-to-energy and iron and steel
  

Spray Dryer Absorber (SDA)

This conventional dry FGD system has been widespread for many years. It’s made up of a reactor followed by a fabric filter. In the reactor, the reagent slurry solution is atomized using either GE’s rotary atomizer technology or dual fluid nozzles, and the droplets react with the gaseous pollutants in the flue gas stream.

• 35-plus years of experience, with more than 100 industrial references and 25 GW installed worldwide
• Up to 95% SO₂ removal, up to 2.5% sulfur in coal
• Wide applicability for various process applications including metals and petrochemical refining, coke ovens, and waste-to-energy.
