UltraTemp Filtration is a new hot gas filtration system that filters fine particulate to extremely low levels.
Corp., a developer of advanced technologies for the control of volatile organic
compounds (VOCs), fine particulate and industrial gases, has introduced
UltraTemp Filtration, a hot gas filtration system that filters fine particulate
to extremely low levels. The heart of the system is a new generation of ceramic
ceramic filters (sometimes called "candle" filters) were manufactured
from high-density granular powders similar to common ceramic products. While
effective, they were brittle and had low thermal shock resistance, so they were
prone to cracking and breakage from thermal shock. As a further drawback, these
older ceramic filters were sometimes hard to keep clean under continuous
with advances in fiber and ceramic technology, these issues have been overcome.
The filters used in the UltraTemp Filtration system are manufactured from a new
generation of low-density ceramic fibers that provide high resistance to
thermal shock. This makes the filters very ductile and resistant to crack
unique composition of the ceramic fibers give the UltraTemp filters an
exceptional ability to capture fine particulates at the fiber surface, without
blinding. They are thus easy to clean using standard pulse-jet techniques.
Being fibrous, rather than granular, the filter elements are also lightweight
and very robust for installation and handling. They have high porosity with low
resistance to flow, which minimizes the number of elements required for a given
UltraTemp Filtration system provides optimal filtration for gases between 400°F
and 1000°F and, in most cases, can be applied to hot gas streams up to a
maximum operating temperature of 1650°F. Typical filtration results are 0.001
grain/dscf (2 mg/Nm3
); many results are a fraction of
this typical value.
UltraTemp Filtration is compatible with heavy
inlet loadings, often above 1 grain/dscf (2300 mg/Nm3
Certain applications involving three or four times this inlet loading still
achieve outlet levels of less the 0.001 grains/dscf. The ceramic filters are
almost completely chemically inert and highly corrosion-resistant.

of the UltraTemp Filtration system include syngas cleaning, glass production,
waste incineration and biomass pyrolysis. Other applications include metal
smelting, mineral processing and chemical production. UltraTemp Filtration is
also suited for ICI boiler MACT compliance for coal, biomass and wood.
UltraTemp Filtration system features an option for the dry injection of calcium-
or sodium-based sorbents for the capture of acid gases. Injected in the duct
upstream of the filter modules, the additional sorbent particulate is easily
captured along with its pollutant gas. For these applications, SO2
removal is typically 80% or better, with removal efficiencies as high as 97%.
HCL removal is typically 95% and often as high as 99%.
need is NOx
, VOC or dioxin removal, UltraTemp filters
are available with embedded catalysts. Urea is then injected upstream of the
removal in these systems is typically above 90%, and
VOC oxidation and dioxin removal are also both exceptionally high. UltraTemp
Filtration can incorporate both sorbent injection and catalyst reduction in a
single system. Acid gases, such as SO2
, and NOx
removed in the same system (see Figure 1).
UltraTemp system uses a baghouse configuration with a reverse pulse-jet
cleaning action. The filters are back-flushed with air, inert gas, syngas or
other appropriate gases. The system has a reliable sealing mechanism that is
easy to access, and the design has been engineered for easy installation and
maintenance. Filter elements are manufactured in various sizes, the largest of
which is 10 ft long and 6 in. in diameter, including an integral mounting
UltraTemp Filtration system is an efficient, proven approach for hot gas
filtration. With over 400 applications worldwide, it is now commercially
available throughout the U.S. with full technical and start-up support.
