Selective Catalytic Reduction (SCR)

Technical characteristics

Advantage:

• High denitrification efficiency: It is the most mature denitrification technology at present, with an efficiency of more than 90%.

• Mature technology and wide application: There are a large number of successful application cases around the world.

• High reliability: The system runs stably.

Summary

SCR technology uses ammonia as a reducing agent to efficiently convert harmful nitrogen oxides into harmless nitrogen and water on specific catalysts through the core chemistry of "selective catalytic reduction". It is a complex system engineering involving catalytic chemistry, fluid mechanics, automatic control and other disciplines. Its efficiency and reliability have made it the mainstream and preferred technology for deep denitrification in coal-fired power plants and industrial furnaces worldwide, making great contributions to improving atmospheric environmental quality and preventing photochemical smog and acid rain.
