Scrubbers FAQ Q. What industrial scrubber handles heavy duty applications involving
corrosive fumes and gases? A. The V/F series provides efficient removal of inorganic gases, odors and fumes.
It’s ideal for gas streams with extreme pH. The V/F scrubber is suitable
for multiple contaminants. Q. What system is recommended for NOx, when the ratio of NO to NO2 varies? A. The Tri-NOx scrubber is well-suited to these applications as it handles any
oxide of nitrogen from any source. Q. Is there a NOx scrubber that guarantees no visible plume? A. Tri-NOx is engineered for zero visible plume, regardless of loading.
For this reason, it is preferred for processes such as metals refining,
chemical nitrations, aluminum anodizing, and nitric etching. Q. How are different local regulations accommodated, without
“over-engineering” or “under-engineering” the scrubber? A. Tri-NOx scrubbers are engineered to specific output restriction for each NOx
component. Some regions require the equipment to maintain specific ppm limits,
generally under 100 ppm and sometimes below 25 ppm, expressed as total NOx,
Other areas require the equipment to reduce NOx expressed as NO2 only. Q. Is there a scrubber that scrub residual inorganics, along with NOx? A. The Tri-NOx system concurrently scrubs inorganic compounds found in NOx
gas streams including sulphur dioxide, chlorine and hydrofluoric acid. Q. What’s involved in handling effluent from a NOx scrubber? A. Our system does not generate toxic or harmful by-products. This
scrubber is chemically safe: waste generated by the scrubber is handled
by basic wastewater treatment. Overflow is pre-treated in the
Tri-NOx tank farm and is pH balanced before discharge. Blow-down rates
from the scrubber process are low per lb. of NOx destroyed by the scrubber. Q. What’s the main difference between an SCR (selective catalytic reduction)
device for NOX and a Tri-NOx scrubber? A. Tri-NOx is not vulnerable to catalyst plugging, and accommodates ambient
gas streams. Also, Tri-NOx will achieve virtually any concentration level at the stack,
and will handle any incoming NO / NO2 ratio. Q. What’s the difference in efficiency between an SCR and Tri-NOx? A. An SCR achieves removal efficiencies of 90-90%. A Tri-NOx system is
engineered to a specific stack output, and can, for instance, reduce loads of
100,000 ppm to below 5 ppm. Tri-NOx is guaranteed to operate within pre-determined
ppm limits for stack output. It is the best choice where NOx is most restricted. Q. What technology is recommended for use with incinerators? A. A Tri-Mer Q-Scrub scrubber with integral quench eliminates inorganic flue
gases from incinerators. It is also suited to thermal oxidizers, calcinators, direct
and indirect-fired kilns. virtually any combustion process that produces corrosive
by-products is appropriate. Q. What is the performance requirement for a scrubber in those applications? A. Standard performance efficiency is 95-99%, depending on user requirement.
The Tri-Mer Q-Scrub can be designed to guarantee any outlet rating. Q. What scrubber provides gas quenching and particulate collection? A. Tri-Mer’s Model QV Quench Venturi scrubber. This packed bed scrubber
collects soluble and insoluble particulate, including submicron particles, and
meets the 0.015 gr.dscf requirement. Q. Are there ways to minimize scrubber height to minimize costs? A. Choice of a tower packing is one effective way. Tri-Mer’s Tri-Packs
media maximizes surface contact within the scrubber between gas and
liquid. It prevents clogging and minimizes wasteful liquid flow down the
wall. It has low static pressure per ft. of scrubber depth.
Q. Are there scrubbers for chrome that don't use lots of energy,
and still meets regs for hex and trivalent chrome? A. The CE-1 scrubber is a low energy unit generating less than 6" of internal
static pressure, therefore energy use is low. Total water use is also low, averaging
15 gallons per gallon for a 20,000 cfm scrubber. The CE-1 is 99.5% efficient for all
types of chrome, including Cr6 and Cr3, regardless of input loading. This system
is all–mechanical and does not consume chemicals. Also important: this
chrome scrubber does not generate waste. Q. Can your scrubbers recycle chrome? A. The CE-1 system can recover chrome, or return it to the plating bath.
Chrome can be recovered from both the gas stream and the filter. This information is for general information purposes only.
