Tri-Mer Corporation offers UltraCat Catalytic Filter Systems that can be integrated with heat recovery and electrical power generation superior to Organic Rankine Cycle (ORC).

UltraCat is the only proven ceramic filter technology on the market, available through Tri-Mer in the U.S. since 2009. No other filter is made like the UltraCat and has its proven operating characteristics and history. Particulate (PM), SO2, HCl, metals, and NOx are removed in a single all-in-one system. Acid gases such as SO2, HCl, and HF are treated with integrated dry sorbent injection. NOx is destroyed by nanobits of SCR catalyst embedded in the filter walls when used in conjunction with integrated ammonia injection. Dioxins and many organic compounds are also destroyed by the proprietary catalyst.

There is a significant installed base of UltraCat systems in the United States. More than 20 glass furnaces are meeting regulatory requirements with the Tri-Mer system. Other applications include solid fuel boilers, RTO exhaust, cement, lime, incinerators, kilns, ships at dock and large-scale stationary diesel.

Tri-Mer offers turnkey services: design engineering, in-house manufacturing, controls, CEM, installation, start-up, power generation, and aftermarket support.

Tri-Mer is the largest supplier of ceramic filter systems in the world.

Tri-Mer catalytic filter systems have much higher temperature capabilities than fabric filter baghouses, and offer much better performance than ESP. Initial cost and operating costs are lower on multi-pollutant applications. In short, filters have unique multi-pollutant features including NOx and dioxin treatment not possible with fabric filters or ESP. Tri-Mer systems have become the technology of choice in many industries. Read the Catalytic Filter page for details.

NOx with PM is treated by Tri-Mer catalytic 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 300°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.

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 on special applications. 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.

CARB Approves First Commercially Ready Ship Emissions Capturing System Read More

Read about Tri-Mer‘s Catalytic Ceramic Filtration System, the heart of METS-1. METS-1 is the first CARB-approved alternative to plugging into shore-based electricity, for reducing at-berth ship emissions. The story is featured in the November, 2015 edition of LAtitude, the official publication of the Port of Los Angeles.

Tri-Mer, the leading provider of furnace emissions control in the U.S., has been awarded two float glass projects by Cardinal Glass Industries. The projects are located in Oklahoma and North Carolina. The selection of the Tri-Mer system signals the Cardinal commitment to using the most advanced emissions control equipment available. The incorporation of the Tri-Mer UltraCat system is in harmony with Cardinal’s philosophy of operating the most efficient glass plants in the world.

Tri-Mer, a world leader in glass emissions technology, has been awarded another glass industry project, this time in the L.A. basin. This brings the number of Tri-Mer Ceramic Catalyst Filter projects in the glass industry to 12. This project will meet EPA requirements and participate in the South Coast AQMD program for reducing NOx, (the NOx RECLAIM program.)

Tri-Mer now has 12 projects on glass furnace emissions in the U.S. that cover the range of glass and furnace types. Systems control glass furnace emissions for PM, SOx, and NOx using Ceramic Catalyst filter technology. 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. Read our latest news item on the Saint-Gobain Dolton project.

Catalytic ceramic filter technology selected for military installation. Tri-Mer has completed a project for a boiler installation at Ft. Irwin, one of the military's premier training facilities. The Tri-Mer system provides regulatory compliance on PM, metals, SO2, SO3, and NOx.

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 Non-Catalytic Ceramic Filter with dry sorbent injection was selected for PM, SOx, and HCl removal, with the option to upgrade a Ceramic Catalyst Filter for NOx removal in the future. A second, larger project uses Ceramic Catalyst filters for PM, SOx, HCl, HF, & NOx.
