摘　　要：研究表明:在燃料燃烧过程中氮氧化物(NO_(x))的生成不可避免,而氮氧化物是形成酸雨以及对臭氧层产生破坏的主要污染物,工业排放氮氧化物已被列为重点控制污染物。目前,乙烯装置裂解炉主要采用低氮燃烧器来降低烟气中的氮氧化物含量。但随着环保要求的进一步严格,必须考虑裂解炉烟气中氮氧化物含量满足更低的排放指标的要求。介绍了国内某新建乙烯装置裂解炉采用SCR脱硝技术的应用情况,并提出优化改进意见。Researches show that the production of nitrogen oxides(NO_(x))is inevitable during fuel combustion,and nitrogen oxides are the main pollutants that form acid rain and damage ozone layer,so industrial emissions of nitrogen oxides have been listed as the major pollutants to be controlled.At present,ethylene cracking furnaces mainly use low nitrogen burners to reduce the nitrogen oxide content of flue gas.However,with the further stringent environmental requirements,the nitrogen oxide content of flue gas from cracking furnace have to meet lower emission targets.This paper introduces the application of SCR denitrification technology in the cracking furnace of a new ethylene plant in China,and puts forward some suggestions for optimization and improvement.
