Study on SNCR+SCR to Eliminate NOx of Ammoximation Tail Gas Process
The current NO,treatment technology in China is summarized and analyzed,and the development of caprolactam production process are summarized.The impact of various indicators on NOx emission values was analyzed.It was determined that the gas consumption was 12 kg/h±1 kg/h,the air volume was 650 m3/h±50 m3/h,the temperature of the SNCR reaction section was 980 ℃±5 ℃,the temperature of the temperature control section was 350 ℃±5 ℃,and the ultra-low emission of NOx could be achieved under relatively economical conditions.
