A sound selective catalytic reduction (SCR) catalyst management program as well as the successful operation of an SCR system will include at a minimum annual ammonia injection grid (AIG) tuning to optimize the NH3:NOx distribution over the cross section of the catalyst bed, minimize ammonia slip and to reduce O&M costs.
CleanAir’s team of experienced engineers using our proprietary flue gas profiling system called the Multi-Point Automated Sampling System (MASS) has provided AIG tuning support to plant operators, engineers and catalyst management providers.
