Odor control in the industrial sectors is a growing concern. As such, odor nuisance does not end at the construction site boundary. These gases, on the other hand, have the potential to harm the environment and individuals working in the industry. Long-term exposure is linked to a variety of health problems, including lung cancer. BossTek, on the other hand, offers a variety of odor control equipment you can use to keep your workers safe while protecting the environment. However, to achieve the best results, these odor control solutions have to be used with the appropriate type of odor source, such as those described below.
Fire has traditionally worked effectively in odor removal. However, complete combustion with the use of an appropriate catalyst needs to be attained for this method to be effective. That’s because; partial combustion produces unpleasant and nauseating aldehydes and formaldehyde. The chemical type of the vapor to be oxidized, as well as its concentration in the incoming stream, influence the temperature required for efficient combustion and deodorization. However, before any combustion can take place, an analysis of the gases and odor characteristics must be carried out to choose the appropriate odor removal method. Additionally, the cost of the combustion process must be considered against the benefits obtained.
Absorption odor control methods may be effective for odor control when odorous particles are soluble in a liquid. The term “absorption” refers to the uniform penetration of the absorbent by gas or liquid molecules. In a liquid, highly soluble gases have a fast diffusion rate. This means that by spraying the liquid through the gas and producing good turbulence on the gaseous side of the interface, resistance to absorption can be reduced. Relatively insoluble gases, on the other hand, have a high rate of resistance at the liquid-gas interface, which affects the rate of absorption. To reduce resistance, the gas should be blasted through the liquid to create instability in the liquid phase and make gas absorption easier.
Odor masking involves replacing one odor with another to produce a fresh and pleasant odor experience. The composition of pre-existing odor is unaffected by a masking agent. However, if there is enough of the masking odor in the air stream, it is picked by the nasal perception when superimposed. There are many different types of organic odor control agents, and each one is unique. Some are foul-smelling, while others are pleasant. They include alcohol, vanillin, heliotropin, methyl ionones, and benzyl acetate. To determine which odor control chemical is suitable, an assessment of the current odor must be performed. Odor masking is cost-effective as there’s no equipment investment required.
Odor counteraction focuses on odor molecules. An odor is a gas molecularly diffused in the air at a concentration sufficient to be perceived above the threshold level. Odor counteractants are most effective when evaporated and molecularly dispersed into the air stream. In severe cases, if dust, fume, and incondensable gases are present in the airborne waste of an industrial process, trapped material should be washed to remove dust and other potentially irritating vapors. Certain pairs of scents in proper relative concentrations are hostile in odor counteraction. Both scents are minimized when the two are sniffed simultaneously.
Each odor released or present in an industry will be unique. As such, an analysis should be done to gauge which method of control will be most effective.
