Selective Non-Catalytic Reduction (SNCR)

SNCR system for NOx reduction
Liquid or gaseous reduction agents are injected into the waste gas through a highly engineered and carefully controlled injection system by the SNCR technology for substantial NOx reduction.

Selective Catalytic Reduction (SCR)

SCR system for NOx reduction

SCR technology converts NOx with a reduction agent to nitrogen and water in the presence of a catalyst. The chemical reaction is selective and this means oxides of nitrogen are preferentially reduced while unwanted side reactions are inhibited.
