摘　　要：目前硫磺回收装置中液硫池废气的处理方法通常是送焚烧炉燃烧后直接排放大气,由此造成烟气中SO_2的排放浓度在标准状态下增加100~200 mg/m^3。为了能满足GB 31570—2015《石油炼制工业污染物排放标准》~[1]的最新要求,有必要对液硫池废气进行处理。介绍了液硫池废气处理的几种新技术,详细分析了各种工艺技术的优缺点。At present,the waste gas from liquid sulfur tank in sulfur recovery unit is usually discharged into the atmosphere after being burned in incinerator,therefore the emission concentration of SO_2 in flue gas increases by about 100~200 mg/Nm^3.In order to meet the latest requirements stipulated in the Emission Standard of Pollutants for Petroleum Refining Industry(GB31570—2015),it is necessary to treat the waste gas from liquid sulfur tank.This article introduces several new technologies for treating waste gas from liquid sulfur tank,and analyzes in detail the advantages and disadvantages of these technologies.
