摘　　要：青岛石化氧化脱硫醇尾气由直接进硫磺焚烧炉燃烧处理,改造为先采用"柴油低温临界吸收-碱液脱硫"技术处理后再进焚烧炉燃烧。"柴油低温临界吸收-碱液脱硫"技术对尾气中油气的回收率高达98%,对硫化氢和有机硫化物的去除率达99%以上。净化气进一步在焚烧炉中深度净化,排放烟气中烃的排放浓度可小于50 mg/m3。同时,尾气处理工艺经过改造后,硫磺焚烧炉排放烟气中SO2排放量和排放浓度也大大降低,为进一步降低硫磺焚烧炉排放烟气中SO2排放浓度奠定了基础。The tail gas treatment technology of “diesel low-temperature critical absorption - desulfurization” was successfully applied in Qindao petrochemical company to treat tail gas from gasoline and LPG sweetening unit which was directly treated through incineration before. The recovery rate of oil vapor was as high as 98%, and the removal rate of sulfide was greater than 99%. The purified gas was further purified in the incinerator, the emission concentration of oil vapor of flue gas was lower than 50 mg/m3.The technology could obviously reduce SO2 emission, and lay the foundation to meet the higher standards.
