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 (100-400 cpsi) • Low-dust flue gas applications(high-grade coal, oil, gas, diesel or WIP applications)
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)
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)
Typical Engine SCR Layout • SCR Catalyst • Catalyst Reactor Housing • Mixing Duct/Static Mixers • Injection Lance • Reductant Dosing & Control System • NOx Analyser (optional) • Soot Blower (optional - not shown) • Reductant Tank
SCR System Silencer Engine Exhaust Pipe Typical SCR Installation on an OGV
SCR Catalysts Extruded Honeycomb SCR Catalyst
SCR Catalyst and Soot Blowers Soot blowing system: • Compressed air (only) in combination with solenoid valves • Recommended for applications with high particle concentration (or special high dust application) • Developed for use in conjunction with the multi-layer concept with reduced air consumption (10-20 Nm3/h)
