SCR Catalyst Performance Update is the Hot Topic for July 23, 2009
SCR's have been used for many years and a lot of research and effort has resulted in improved performance for catalysts. Catalyst and SCR suppliers have improved mechanical strength, reduced plugage problems, reduced pressure drops, minimized corrosion issues and extended the life of catalysts. They and others have also introduced optimization software and monitoring techniques to help improve catalyst life and performance. This Hot Topic Hour is intended to provide an update on these developments and the other issues related to catalyst performance.

How can the performance of a NOx Control system be maximized while minimizing the maintenance? What are the optimum catalyst selections for SO3 minimization and mercury oxidation? Is catalyst poisoning still a problem? How can the life of the original catalyst be extended? Does a regenerated catalyst require more frequent replacement? Is it necessary to tune the SCR tuning every time boiler and operating conditions change? Does co-firing of biomass have a significant impact on the performance of CR's? Does seasonal or intermittent operation impact the life or performance of the catalyst?

The following speakers will discuss these issues:

Larry Muzio PhD, FERCo will answer the question "Why Doesn't the SCR Work?" Over the years, FERCo has performed numerous projects diagnosing performance issues with SCR systems. A number of tools have been developed to better understand problems including: AIG tuning, velocity maldistributions, AIG ammonia oxidation, gas inleakage, and catalyst activity issues. Larry's presentation will provide an overview of this experience and the tools employed.
Volker Rummenhohl, Vice-president of Catalyst Technologies at Fuel Tech, Inc. will present the startup results from two new 680 MW SCR systems. The high performance of the catalyst in these systems is due to advanced flue distribution devices recently introduced to the market. His presentation will also reference additional cost savings for future, high performance advanced SCR systems.
Mike Mattes, Executive Vice-president, CoaLogix/SCR-Tech Mattes will speak about recent technological advancements in SCR catalyst regeneration, including breakthroughs in NOx reduction, SO2 conversion, mercury oxidation and overall catalyst performance. Mr. Mattes will also speak about the role of SCR catalyst regeneration in a market of increased catalyst demand domestically and internationally.
Thomas "Nathan" White, Sr. Account Executive at Haldor Topsoe
Stephen Guglielmo, SCR Catalyst Product Manager at Hitachi Power Systems America, Ltd.
