Successful SCR catalyst management depends on the ability to accurately plan and predict the replacement or addition of new catalyst layers in order to maintain the necessary NOx reductions and ammonia slip and is a task that is not easily done or taken lightly. If SCR catalyst is replaced too soon, operating costs can increase; but if the catalyst is replaced too late (it is allowed to degrade too far), unplanned outages may become necessary, or NOx reductions may have to decrease, possibly resulting in penalties. Failure to plan properly in either direction will inevitably result in the same unwanted scenario of higher costs.
There are numerous factors that need to be considered when making an informed decision about SCR catalyst management, and without the proper tools, the process can quickly become overwhelming. CatalysTraK® - Manage was developed to provide a means of streamlining and organizing the management process.
The main goal of CatalysTraK® - Manage is to take the guesswork out of catalyst replacement decisions. By entering data about your specific SCR reactor, such as size, catalyst type, number of layers, outage schedules, etc., CatalysTraK® - Manage not only determines when catalyst additions or replacements are necessary, but also provides options based on your outage schedule, and calculates the associated economic consequences.
