7 SINOx ® : Coated Honeycomb SCR High specific surface area High activity in low-dust flue gases (low volume) Optimised pressure drop (thin metallic walls) Variable length and number of cells ( cpsi) Low-dust flue gas applications (high-grade coal, oil, gas, diesel or WIP applications)

8 SINOx ® : Extruded Honeycomb SCR High specific surface area High activity in low-dust flue gases (low volume) Optimised pressure drop Variable length and number of cells (6-300 cpsi) Low-dust flue gas applications (high-grade coal, oil, gas, diesel or WIP applications)

9 SINOx ® : Coated Plate SCR Variable pitch, minimal dust deposition High erosion, poison resistance Low pressure drop Plate-to-plate clearance, variable SSA High-dust flue gas and special applications (coal- fired, industrial processes & refinery power plants)
