齐鲁石化100kt/a硫磺回收装置的运行总结

摘要

Technological process,technical characteristics and operation of the100 kt/a sulphur recovery unit of Qilu Company are introduced. Main burner with NH3deconstruction and Low NOxincinerator burner are designed and provided by Duiker Combustion En-gineers B.V. Liquid sulphur degassing uses the LS-DeGAS patent technology by Qilu Research Institute. The SRU runs stably. The av-erage concentration of sulphur dioxide emissions is 50~80 mg/m3,the lowest is 20 mg/m3,and the NOxemission mass concentration is 20~40 mg/m3,which can meet the new national environmental protection emission standard.%介绍了齐鲁公司 100 kt/a 硫磺回收装置的工艺流程、技术特点和运行情况.制硫燃烧炉及尾气焚烧炉分别选用杜克公司生产的烧氨型和低氮氧化物型燃烧器.液硫脱气采用齐鲁公司研究院 LS-DeGAS 专利技术.该装置运行稳定,二氧化硫排放质量浓度平均为50~80 mg/m3,最低可达20 mg/m3,氮氧化物排放质量浓度为20~40 mg/m3,能够满足国家新的环保排放标准.
