The principle of SCA selective catalytic absorption technology was analyzed,and the application of this technology in cement production was summarized and analyzed.The application results show that when the SNCR technology cannot control the NOx emission concentration below 50 mg/Nm3,the SCA selective catalytic absorption technology can reduce the NOx emission concentration at the kiln tail to less than 30 mg/Nm3 within 2 min,which meets the ultra-low emission requirements,and the cost per ton of clinker is about 2.2 yuan.
