Air Quality Control Systems (AQCS)
Optimization of SCR Operation and Maintenance / Catalyst Replacement
As an SCR system supplier, Mitsubishi Power offers various after-sales services such as operation and maintenance efficiency plan, and SCR performance optimization by evaluating catalyst samples against actual plant operating condition and diversified flue gasses.
The SCR catalyst is a key element in the SCR system and, in order to maintain SCR performance, requires installation and replacement as it gradually deteriorates from the flue gas composition over years of operation.
We offer wide-ranging catalysts with high reliability contributing to increased NOx removal efficiency, low SO2/SO3 conversion rate, low pressure loss, Hg oxidations and dioxin removal.
