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.
