KEMA developed a validated model for calculating activity, lifetime, replacement strategy and design of a Selective Catalytic Reduction (SCR) installation. NOxVision helps optimize the efficiency of an SCR installation by revealing what measures must be taken to operate the SCR installation under optimal technical and economic conditions. The momentary condition and remaining lifetime of the catalysts inventory is calculated based on on-line or lab-scale activity measurements. The most advantageous order of replacing specified catalyst layers in the SCR installation and the rate of return on the investment is also provided.
The unique feature of NoxEye is that it takes into account existing NOx, NH3, temperature and velocity profiles of the flue gas entering the SCR unit. This enables KEMA to provide you with the best diagnosis of and solution to your problem.
This validated modeling tool can be used to:- design a new SCR installation or optimize the efficiency of an existing SCR installation
- reveal under what conditions your SCR installation should be operated with both optimal technical performance and economic benefits for your company
- calculate the activity and the velocity of deactivation of your SCR catalyst as a function of the time on stream from both off-line activity measurements
- enable on-line catalyst management and direct insight into the (long-term) technical and economic effect of firing a new fuel (or co-firing of secondary fuels)
- answer your most urgent question: when and how must I change or replace the catalyst layers in the SCR unit while taking into account the expected (long term) fuel input and its specific effect on the catalyst activity, the required SCR performance and emission constraints and plant overhaul schedules?
- provide the optimal solution for problems regarding sudden unexpected loss of activity leading to high NOx emissions, high NH3 breakthrough or ash contamination, required retrofits and obtaining up-front information on the impact of (co-) firing new fuels.
