Odor Scrubber

What’s a realistic efficiency target for an odor scrubber?

Many odors, including those that are formally regulated, “nuisance” odors, are detectable below 1 ppm. Therefore, an odor control scrubber that warrants a mass reduction to below 1.0 ppmv is needed.

Is there a “high” or “low” air volume for a single odor scrubber?

The volume of gas that can be accommodated by a single stage odor scrubber assembly is between 25 scfm (6" Ø to 75,000 scfm (15' Ø cfm.)

Is it possible to engineer an odor scrubber for odors and corrosives?

Yes, the Tri-Mer odor scrubber system can simultaneously reduce N/S based odors and other industrial corrosives, both alkali and acid-based.

Will an odor scrubber tolerate particulate and other contaminants?

Tri-Mer odor control scrubbers are unaffected by dirty gas streams containing submicron and larger particulate, and various inorganic scrubber compounds in addition to the primary odor constituent.

Water rates are high in our location. Is there an odor control scrubber that uses very little water, even when loadings vary?

Tri-Mer odor scrubber technology uses very little water and yields a clean stack under all loading conditions. Water use is always dependent on the inlet load and contaminant, salt generation and, most importantly, the heat generated from the first two items. Knowing the inlet load in lbs./hr. or ppmv on a consistent basis, will help with the ratio of purge water to waste chemical.

How important is packing media to the efficiency of an odor scrubber?

If chosen properly, packing media minimizes the design size of the odor scrubber. Media also influences scrubber efficiency: if it provides maximum surface contact between the gas and the scrubbing liquid, as is the case with Tri-Mer’s Tri-Packs packing media, it facilitates continuous formation of droplets throughout the packed bed. This is what allows scrubbing efficiency to be high and operation costs to be kept low.

Are there other characteristics of packing media used in an odor scrubber that are important?

Yes – if the media is engineered for superior wetting, it will help maintain liquid distribution throughout the packed bed, which enhances scrubber efficiency.

Is occasional clogging of the scrubber tower packing inevitable?

No, some odor scrubber packing won’t clog under any operating conditions, because it has no flat surfaces or minute openings to harbor particulate. This particular design also prevents compression interlock, a common phenomena which decreases the operating efficiency of the odor control scrubber.

If the process changes, how easy is it to adapt the odor scrubber to the new requirement?

Tri-Mer OC systems are flexible. If there is an impending process modification, Tri-Mer engineers will access the new input data to determine the feasibility of existing equipment. Often, a modification in scrubber operation such as chemical feed or liquid flow rate is all that is needed.
