Dry scrubbers

• SOx removal using lime slurries or other scrubbing agents

FGD (Flue Gas Desulfurization)

• Spray lime slurry or other scrubbing fluid into flue gas from coal-fired power plants to absorb the sulfur oxides created during the combustion process
• Due to the erosive nature of many scrubbing fluids, high wear-resistant materials for this application include silicon carbide (SNBSC and RBSC) as well as cobalt alloys.

Odor control

• Spray liquids to mask or chemically alter the smell of products, waste, process streams, or exhaust gas

Packed bed scrubbers

• Acid scrubbers
• Hydrochloric (HCl), sulfuric acid (H₂SO₄), nitric (HNO₃), or
• hydrofluoric (HF) acids
• Halogen removal
• Cl₂, Br₂, F₂
• Ammonia/amine scrubbing

SCR/SNCR applications

• Control NOx emissions using ammonia (NH₃) or urea solution.
• Nozzles spray ammonia or urea solutions to absorb nitrogen oxides produced by combustion processes in which environmental regulations limit emissions.

Venturi scrubbing

• 一种气体气体通过th擦洗rough a narrowed section of ducting where high velocities help to ensure thorough mixing and contact between the gas and scrubbing fluid

Water wash injection

Aeration Air Stripping

• Use air stripping and spray aeration nozzles to expose contaminated water to air to remove volatile organic compounds (VOCs) and trihalomethanes (THMs).
  • Increasing the surface area of the contaminated water exposed to the air removes unwanted chemicals through diffusion.
• Open and packed tower arrangements
  • Whirl nozzles increase uniformity above the packing.
  • Spiral nozzles provide smaller droplet sizes in direct contact applications.

Toxic Gas Mitigation Applications

• When toxic gas storage systems experience unexpected leaks or breakage, spray nozzles envelop the tank or piping system in a cloud of protective spray that absorbs the gas to prevent dispersion into the air.
