摘要
催化裂化原料中含有氮化物,在经过反应烧焦再生后,原料中的氮化物会转变为氮氧化物(NO_(x)),并跟随烟气排放至大气中,污染环境。本文对烟气中CO含量、O_(2)含量、温度、注氨量等进行研究,分析了影响再生烟气中NO_(x)含量的因素,总结NO_(x)生产规律,并提出NO_(x)排放控制措施。
Catalytic cracking feedstock contains nitrogen co mpounds,which will be converted into nitrogen oxides(NO_(x))after reaction and coke burning regeneration,and will be e mitted into the at mosphere with the flue gas,polluting the environ ment.This article studies the CO content,O_(2) content,te mperature,and a mmonia injection a mount in flue gas,analyzes the factors that affect the NO_(x) content in regenerated flue gas,su mmarizes the production rules of NO_(x),and proposes measures to control NO_(x)e missions.
