摘　　要：某公司催化裂化装置因生产加工的减压渣油中硫含量较高,造成烟尘中SO_(3)含量比较高,所形成的H_(2)SO_(4)气溶胶导致烟气出现蓝烟拖尾状况。采用SNAR清洁型选择性非氨基还原除酸脱硝技术进行试验,结果表明,SNAR生产工艺在高温段下NO_(x)的脱除率达80%~95%,而且无氨逃逸存在,SO_(3)的总体脱除率达60%~80%,蓝烟拖尾状况有明显改善,同时未对生产线设备产生腐蚀等不良影响,为催化裂化设备安全运行增加了经济收益和环境效益。The content of sulfur in vacuum residue produced and processed by the catalytic cracking unit of a certain petrochemical company is high,causing high SO_(3)content in the soot,which forms H_(2)SO_(4) aerosol leading to blue smoke tailing in flue gas.SNAR clean selective non-amino reduction deacidification-denitrification technology independently developed by Qingdao Huicheng Environmental Protection Technology Group Co.,Ltd.is tested.Results show that the removal rate of NO_(x)by SNAR production process reaches 80%-95%in the high-temperature section,and there is no ammonia escape.The overall removal rate of SO_(3)is 60%-80%,and the blue smoke tailing situation is greatly improved.Meanwhile,there are no adverse effects such as corrosion on the production line equipment,which increases the economic benefit and environmental benefit for safe operation of the catalytic cracking unit.
