Horizontal Crossflow Scrubber guarantees your operating permit level out the stack for HCl, HNO3, HF, H2SO4, Cl2, H2S, NH3, and other contaminants.
Tri-Mer Crossflow scrubs virtually all inorganic compounds, and
maintains stack emissions to specific ppm levels determined by local
permit requirements for all input concentrations. Specific outlet
requirements based on percent removal can also be guaranteed. View our

the performance of this industrial equipment is high-flow liquid
recirculation, which produces intense contact between the contaminant
and scrubbing liquid.
industrial system configurations are available. The internal tank/ANSI
pump design is manufactured in capacities of 50 cfm through 100,000
cfm. An internal Tank/Vertical pump design is available for 50 cfm
through 60,000 cfm applications. An External recirculation System/Dry
Sump design is available in single or multiple stage options, with a
maximum single unit capacity of 120,000 cfm.
Tri-Mer Ultra-Scrub Crossflow versions operate with zero production
down time, because critical system modules have full redundancy.
Back-up readiness is assured through regular auto hand-over from
primary systems. This feature significantly reduces both monitoring and
maintenance requirements, and assures full operation, even during
normal maintenance of the equipment.
industrial scrubbers are supplied with control panels and operator
interface. Standard material of construction is UV stabilize
polypropylene. PVC and stainless steel are optional materials. Tri-Mer
Crossflow scrubbers use Tri-Packs tower packing and high-efficiency
industrial mist eliminators. Quench equipped systems can accommodate
inlet temperatures to 2000°F.
broad range of industrial manufacturing and process industries. Also,

Crossflow Industrial Scrubbers operate at velocities between 150 and
500 ft./min. The exact operating parameter depends on:
translates into residence time. Residence requirements in the system
can vary from 1⁄2 second to several seconds. This variable is specified
by Tri-Mer engineering on an individual basis.
INLET / OUTLET LOAD FACTORS
a specific system guarantee regarding removal efficiency, it is
necessary to have a definition regarding input vs. output. This number
is expressed as mass emission per hour in vs. out. Volumetric
expressions, including ppmv, are also appropriate.
gas flow through the scrubber system, expressed in cu. ft/min.(cfm), is
an important factor in the design of the scrubber vessel. Since
residence time in the scrubber is a critical design consideration, the
volume of air passing through the scrubber directly affects the cross
INLET GAS TEMPERATURE
metal finishing applications operate under 100°F inlet temperature.
Tri-Mer Crossflow Systems can accommodate inlet temperatures from
ambient to over 2000°F. High temperature systems require a gas quench,
integral to the system.
GAS STREAM PROFILE
the gas stream variables, which include residuals riding in the gas
stream in addition to the primary contaminant to be removed, is
crucial. Residuals may not be of primary interest from the standpoint
of removal efficiency, but could affect system chemistry, or, if
particulates are involved, may restrict flow if not accommodated.
SYSTEM BLOW-DOWN RATES
rates are determined by the chemistry involved within that scrubber.
Systems requiring low ppb outputs require higher water blow-down
capacities than systems operating higher output dynamics. Specific
multistage systems may require multiple blow-down points to a final
ratio is determined by the items discussed earlier. System removal
requirements play an important role. Tri-Mer engineering will be
responsible for calculations.
