Odor Control Nozzles

Spray odor absorbing, neutralizing, or covering agents

Questions? Ask an Engineer

Many industrial process such as waste storage, incineration, waste water treatment, chemical processing, food processing, etc. contain organic and inorganic compounds that are capable of producing odors that are unpleasant and must be treated to make the work area and surrounding area acceptable. There are three categories of treatments that can be sprayed through nozzles to control the odor: coverants, deodorants, and absorbents. These treatment can be used in open type or packed bed type scrubber systems.

  • Coverant: a coverant is a better-smelling substance sprayed to mask or hide the bad odor.
  • Deodorant: a deodorant is a liquid used to to chemically change or break down the pungent molecules in an odoriferous area or air stream, effectively neutralizing them.
  • Absorbent: an absorbent is a liquid that actually absorbs the bad odor of a foul smelling gas stream into the liquid, reducing the potential odor of the remaining gas.
    • Depending on the odor source, water can often be used as the absorbent liquid.

In open type scrubber systems, BETE misting and air atomizing nozzles are generally the most effective for odor control applications based on the fine drop size they produce, increasing the surface area there is to compete with, react, or absorb the odor to be controlled. In packed bed type scrubber systems, BETE axial whirl nozzles are generally the most effective for achieving even distribution over the packing surface and ensuring no gas bypass through the packing.
 

Selecting an Odor Control Nozzle:

Important factors to consider:

  • Applicable design specifications and requirements
    • Open type scrubber or packed bed type scrubber
    • Coverant, deoderant, or absorbant
  • Process pipe/duct/vessel size, velocity, pressure, temperature, and fluid composition
  • Required materials of construction for corrosive environments
  • Spray media density and viscosity
  • Required spray media flow rate
  • Available pressure drop (∆P) across the nozzle
    • ∆P = supply pressure at nozzle inlet - process pressure outside nozzle
  • Our experienced engineers can help determine which nozzle will perform as required with your design details
