Tri-Mer Corporation, specializing in the control of fine particulate and pollutant gases, has introduced UltraTemp Filtration, a hot gas filtration system that captures particulate, including submicron and ultrafine particulate, to low levels.
The heart of the UltraTemp Hot Gas Filtration System is a new generation of ceramic filter tubes, manufactured from low-density ceramic fibers. These filter tubes provide exceptional resistance to
thermal shock and crack formation.
Typical particulate removal with the system runs to less than 0.001 grains/dscf (2 mg/Nm3).
The system incorporates dry sorbent injection for efficient dry scrubbing of SO2, HCl, and other acid gases. Typical SO2 and HCl results show up to 98% removal.
Using filter elements with embedded nano-bits of SCR catalyst, urea/ammonia is injected upstream of the filter housing, yielding a high degree of NOx control. Typical NOx results indicate up to 95% removal.
The Boiler MACT also regulates carbon monoxide (CO). In general, if CO is managed in the boiler, outlet NOx rises, and vice versa. The best strategy for Boiler MACT compliance is to control CO in the boiler,
and allow the UltraTemp system to remove the NOx. The filters are also efficient at removing dioxins.
Mercury removal is achieved using activated carbon sorbent. Higher-temp zeolite sorbents also show promise.
Tri-Mer’s UltraTemp Hot Gas Filtration system uses a baghouse configuration with a reverse pulse-jet
cleaning action. The filters are backflushed with air, inert gas, syngas, or other appropriate gases. It 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 flange.
Pressure drop across the system is approximately 8 inches w.g.
