Tri-Mer Corp has introduced a hot gas filtration system that filters find particulate to low levels. The UltraTemp hot gas filtration system provides optimal filtration for gases between 400-1000 deg F and in most cases can be applied to hot gas streams up to a maximum operating temperature of 1650 deg F. Typical filtration results are 0.0001 grain/dscf (2mg/Nm3); many results are a fraction of this typical value. UltraTemp filtration is compatible with heavy inlet loadings, often above 1 grain/dscf (2300mg/Nm3). The ceramic filters are almost completely chemically inert and highly corrosion-resistant. At the heart of the system is a recently developed ceramic filter generation. Earlier generations - sometimes called candle filters - were manufactured from high density granular powders, similar to common ceramic products. While effective, they were brittle, with low thermal shock resistance and were prone to cracking and breakage from thermal shock.
