Topsoe and Unifrax establish partnership to market improved ceramic catalytic filters to the industrial market

The TopFrax™ catalytic candle filter

Unifrax I LLC (“Unifrax”), the Tonawanda, New York based manufacturer of specialty fiber products, and Haldor Topsoe A/S, a world leader in catalysis and related process technologies headquartered in Denmark, today announced the signing of a partnership agreement. The partnership marks the beginning of a joint global effort by the two parties to commercialize an innovative new line of catalytic filter candles.  This new product family will be marketed as TopFrax™ filters and was developed for catalytic hot gas filtration in the industrial market.

The partnership combines the expertise and knowhow of Topsoe’s leading position within catalysis and Unifrax’ strengths within fiber filter manufacturing and filtration. The TopFrax™ technology offers improved catalytic filters to the global market, providing high quality, well-engineered products and technical support to customers in a broad range of industries such as glass, cement, bio mass, waste incineration and metal production.

Global regulations have reduced the permissible levels of particulate and hazardous gas emissions, making compliance costly and requiring companies to make substantial investments in pollution control technologies.  Haldor Topsoe and Unifrax have worked closely to develop a unique technology that addresses the problems related to industrial emissions. TopFrax™ catalytic filter candle is designed to remove NOx and particulate matter, and will also be launched in a version capable of removing VOC, CO and dioxin that are generated in many industrial processes.

Key features of these filters include: high efficiency filtration of particulate matter (+99%), NOx removal efficiency (+95%), low ammonia slip, and filter porosity above 80%. TopFrax™ filters have a temperature use limit of 400°C (750°F), are compatible with sorbents, non-combustible, and corrosion resistant.  These innovative, high quality candle filters give equipment builders and customers a unique technology combining the removal of NOx, VOC, CO, dioxin and particulate matter in one integrated process.  Designing pollution control equipment around TopFrax™ hot gas filters saves CAPEX and OPEX and reduces the footprint of the installation while providing extended service life and energy savings.

“The TopFrax™ product line is the first in the world to introduce a combined process for removal of NOx, VOC, CO, dioxin and particulate matter enabling customers to meet increasingly stringent regulations in a cost effective way. The partnership offers exciting possibilities for both parties, not only in terms marketing the new catalytic candle filters, but also in developing other products together in the future,” says Bjerne S. Clausen, CEO of Haldor Topsoe A/S.

David E. Brooks, Unifrax President & CEO comments: “Unifrax is proud to partner with Haldor Topsoe, a world leader in developing catalysts to solve a range of emission control problems. The commercialization of TopFrax™ filter candles is in alignment with our company mission of helping customers reduce emissions and save energy.  The partnership will help both companies better serve the customer by providing access to a complete hot gas filter portfolio and extensive product support worldwide.”
