MEiN).
The aim of the work was to develop a fast method of measuring the activity of the entire catalytic layer, a precise method of determining the lifetime (deactivation characteristics) of the catalyst and the construction of an SCR reactor computer tool (based on the so-called "Digital Twin" and machine learning) for determining the lifetime of DeNOx catalysts depending on history of their use and expected further operating conditions.
The SCR-DT software was developed, installed and launched on a server installed in the local network of PGNIG TERMIKA SA. Application of the SCR-DT software makes it possible to reduce the operating costs of catalysts through better maintenance management, extending the periods for their regeneration/replacement and reducing the amount of waste, thanks to the accurate prediction of their deactivation time and the development of recommendations for their optimal operation.
