摘　　要：介绍了LS系列硫回收催化剂在石家庄炼化80 kt/a硫磺回收装置上的工业应用情况。装置标定结果表明:在不同运行负荷下,装置各项参数运行正常,生产的硫磺产品各项指标均满足GB/T2449.2—2015《工业硫磺第2部分:液体产品》优等品的要求,净化尾气中COS的体积分数低于0.002%,硫回收率为99.99%,催化剂性能满足装置技术要求,排放烟气中SO_(2)、NO_(2)的质量浓度低于50 mg/m^(3),满足GB 31570—2015《石油炼制工业污染物排放标准》的要求,LS系列硫回收催化剂在石家庄炼化的工业应用取得成功。The industrial application of LS series sulphur recovery catalysts in 80 kt/a sulphur recovery unit of Shijiazhuang Refining & Chemical Branch is introduced. The calibration results of the device show that all parameters of the device operate normally under different operating loads, and all indicators of the sulphur products produced meet the requirements of first-class products in the national industrial sulphur standard GB/T 2449.2-2015 Sulphur for industrial use — Part 2: Liquid product. The volume fraction of COS in the purification exhaust is lower than 0.002%, and the sulphur recovery is 99.99%. The performance of the catalysts meets the technical requirements of the device. The emission concentration of SO_(2)and NO_(2)in the flue gas is lower than 50 mg/m^(3), which meets the requirements of GB 31570-2015 Emission standard of pollutants for petroleum refining industry. LS series sulphur recovery catalysts has been successfully applied in Shijiazhuang Refining and Chemical Branch.
