Glass Furnace
Emissions Filters

  • Long catalyst life

  • Lower TCO than ESP

The majority of U.S. facilities seeking control of glass furnace emissions have chosen Tri-Mer UltraCat Catalytic Filter Systems.

Worldwide, more than 3 dozen glass furnaces use Tri-Mer ceramic filter technology and advanced Tri-Mer system design. These systems are operating in flat glass, container glass, and tableware. In the United States, Tri-Mer Catalytic Filter Systems readily meet EPA and state requirements for particulate (PM), SO2, HCl, metals, and NOx.

Glass Furnace Filter System

Tri-Mer’s UltraCat is an ideal solution for glass furnace emissions for these reasons:

  • NOx removal is a small fraction of the “cost in $/ton of glass” of converting to oxy-fired.
  • Tri-Mer’s integrated glass furnace emissions system is less costly than ESP ducted to a stand-alone SCR. UltraCat Catalyst Filter projects have been awarded primarily on initial price and operating cost, with superior performance an important added benefit.
  • Catalytic Filter Systems require much less sorbent than ESP to achieve equivalent SO2 removal efficiency. This advantage is greatly magnified by the exclusive Tri-Mer Sorbert-Saver technology.
  • Catalytic Filters use less energy than ESP + SCR.
  • Total “cost of ownership” is lower, even with filter replacement at the 10-year minimum. Catalytic filters currently (2018) have a nine year proven history in glass, with no signs of filter or catalyst failure.
  • The Tri-Mer system is less complicated, and requires less maintenance, than ESP + SCR.
  • Systems are “future-proof” with significantly higher PM capture (including metals).
  • When DSI (dry sorbent injection) is used for acid gases, Catalytic Systems have higher SO2 capture potential than ESP.
  • UltraCat Filter Systems have longer catalyst life because the catalyst is protected within the filter media.
  • Tri-Mer’s UltraCat is all-in-one: PM+SO2+metals+NOx, and requires less total footprint.
  • Tri-Mer’s overwhelming experience in contrast to the competition insures a proven system design, and guaranteed on-time schedules on-budget project delivery.
