摘　　要：介绍了中原油田普光分公司天然气净化厂液硫池脱气尾气的回收利用情况。液硫池脱气采用机械与空气组合脱气工艺,尾气采用蒸汽喷射器送至Claus炉回收利用。该改造技术对Claus炉H2S和SO2比例调节和炉膛内部反应不会造成较大影响。改造后硫磺总回收率提高0.01%,排放尾气中SO2质量浓度低于290 mg/m3。Tail gas recycling utilization of liquid sulphur tank degassing process in Natural Gas Purification Plant of Zhongyuan Oilfield Puguang Branch of is described. Liquid sulphur tank degassing process combined mechanical with air. The tail gas was sent to Claus furnace for recycling through the steam-jetting pump. The upgrading technology has not much impact on the ratio of H2 S to SO2 as well as the internal reaction of Claus furnace. The technology increase the total sulphur recovery rate by 0. 01%,with mass concentration of SO2 below 290 mg / m3 in tail gas emissions.
