As the operation of SCR reactors changes from seasonal to year-round, the opportunity for physical removal of catalyst samples for laboratory activity testing will become less frequent. Since catalyst management strategies rely on accurate knowledge and estimations of catalyst life, the decline in the amount of data available will lead to less accurate predictions which could in turn lead to higher operating or replacement costs.
In response to the need for more frequent measurements of catalyst activity, FERCo developed the Knoxè In Situ Catalyst Activity Test System , capable of measuring catalyst activity across multiple locations and multiple layers in an operating, full-scale SCR reactor.

Why Online Activity Tests are Needed
Until now, catalyst activity was determined by removing a physical sample of catalyst from the reactor and analyzing the activity in a laboratory. This limits the amount of activity data to about one sample a year, or less for SCR systems operating year-round. With limited data, projecting catalyst life is difficult and can result in higher SCR costs.
However, with the Knoxcheck® in situ test system, catalyst activity can be measured at any time, on any layer while the SCR system is on-line (in addition to regular external lab analysis of catalyst samples).

The KnoxCheck® test system is easy to install. Each typical test location requires only two standard 4” ports, one upstream and one downstream of the catalyst layer. Test as many locations per reactor as needed. All locations are managed by one control cabinet. |
Remote Monitoring
With the Knoxè In Situ Catalyst Activity Test System , you can get real-time catalyst activity measurements at multiple locations on each layer of catalyst. Additionally, the system is fully-automated, and can be conveniently operated remotely, via your internal network or the internet, at the plant, in your office, even on the road. If desired, FERCo can operate the Knoxè In Situ Catalyst Activity Test System for you from our main office and can even help with your catalyst management decisions.
