Tri-Mer's UltraCat Catalyst filters remove particulate (PM), acid gases
such as SO2 and HCl, and NOx in a single all-in-one system. UltraCat
catalyst filters are composed of fibrous ceramic materials that can
withstand high temperatures up to 1650° F. The filter walls have nanobits
of highly-efficient SCR catalyst for NOx control. Destruction of NOx is
effective at temperatures as low as 350° F. Acid gases are removed in
the same system with integrated dry sorbent injection of sodium bicarbonate,
trona, or lime. Dioxins are also destroyed by the proprietary catalyst.
Tri-Mer ceramic filter systems provide much higher temperature
capabilities than fabric filter baghouses, with much better performance, yet
are still cost competitive with ESP. Total operating costs are lower. In addition,
filters have unique multi-pollutant features including NOx and dioxin
treatment not possible with fabric filters or ESP. UltraCat has become
the technology of choice in many industries. Read the Hot Gas Filtration page
For applications below 300°F, Tri-Mer's Cloud Chamber System (CCS)
treats PM2.5, fine, submicron, ultrafine, and condensable particulate,
as well as PM10, while simultaneously wet scrubbing soluble gases.
The CCS is an attractive alternative to wet ESP. The Cloud Chamber
Scrubber uses charged droplets – not charged particles – and
consequently requires less energy. Acid gases and other soluble
gases are scrubbed at 99% efficiency.
NOx with PM is treated by the UltraCat catalyst filter systems. For NOx removal on applications without PM in the gas stream, Tri-Mer offers two distinctive stand-alone solutions, both with exceptional track records. Standard SCR units from Tri-Mer come in both low-temp and high temp versions, covering a temperature range of 350°F to 1100°F.
For colder sources and/or exceptionally low removal requirements –
as low as 1 ppmv – the Tri-NOx Multi-Chem system accommodates
any combination of NO and NO2, and guarantees a clear stack.
At Fabtech 2013, Tri-Mer will introduce the Laser Chiller / Dust Collector Combo Unit. Its air-cooled water chiller is engineered for heavy-service laser heads and optics, and delivers reliable ± .5° uniformity. MERV 16 filters are 99.999% efficient on 0.5 micron and larger particles by weight. more
Tri-Mer now has six projects on glass furnace emissions in the U.S.
that cover the range of glass and furnace types. The latest system controls
glass furnace emissions for PM, SOx, and NOx using the
UltraCat catalyst filter system. Tri-Mer ceramic filter systems have
become the technology of choice for float, container, and glassware
projects, and both air-fuel and oxy-fired furnaces.

Boiler MACT compliance. The American
Council of Engineering Companies (ACEC) has awarded Tri-Mer and its
fellow team members the Grand Place Award for Engineering Excellence,
Energy Production Category, for 2013. Tri-Mer supplied the UltraCat
catalyst filter system to control boiler emissions - PM, NOx, and CO -
for the University of Iowa. The ceramic filter system can be configured
to remove acid gases, including SO2 and HCl, as well as mercury and
RTO applications are growing. Tri-Mer has
completed the first of two projects for control of PM, NOx, and dioxins
following existing thermal oxidation equipment. The firms are Fortune
100 and Fortune 100 Fastest Growing companies in the high tech sector. A
third is in the energy recovery sector. Pending projects include
cleaning the gas stream prior to thermal oxidation.
Tri-Mer has also been awarded projects
by companies that treat industrial kiln emissions. The
UltraTemp high temperature filter system with dry sorbent
injection was selected for PM, SOx, and HCl removal, with the option to
upgrade to UltraCat catalyst filters for NOx removal in the future. A
second, larger project uses UltraCat filters for PM, SOx, HCl, HF, & NOx.
These projects became operational in 2012.
