Odor Control Scrubber

Explanation

The accumulation, transport, and processing of sewage results in the generation of harmful gases and odors. Chemical scrubbing is a gas scrubbing method in which contaminants are removed from the gas stream. During this process the gas stream passes through a packed structure with a large wet surface area. The wet area enables contact between the gas and the scrubbing chemicals and allows for removal of contaminants from the gas stream.

  • Custom designed systems
  • Options to be retrofitted with current equipment
  • Media options
  • Faster commissioning time
  • Continuous monitoring
  • In-house designed and manufactured control panels
  • Sized system process fans
  • Portable options and sizes available

Mechanism

The gas is contacted with an acetic scrubbing liquid to neutralize the ammonia emission. H2SO4, at 10% concentration, is used down to a pH of 2. High-efficiency Tri-Packs packing media is an integral part of the system; load inlet ppm determines packing depth. Scrubbing efficiency in all cases is to below detectable limits.

Air is contacted with an alkali scrubbing liquid such as sodium hydroxide. Sodium hypochlorite and similar oxidizers may be added to enhance scrubber efficiency.

Applications

  • Vapor Phase Odor Control
  • Applications include chemical plants, petrochemical facilities, municipal waste treatment, asphalt manufacturing, foundries and food processing.
