摘　　要：通过对镇海炼化100kt/a硫磺回收装置影响SO2排放因素的分析,采取优化催化剂级配、换用进口高效脱硫剂、吸收塔后增设碱洗塔、液硫池废气改入反应炉处理等措施进行技术改造,使外排烟气SO2质量浓度远低于GB31570—2015《石油炼制工业污染物排放标准》中规定的100mg/m^3指标限值要求。Based on the analysis of factors affecting SO 2 emission from a 100 kt/a sulphur recovery unit in Zhenhai Refinery and Chemical Company, technical reforms are carried out by optimizing catalyst gradation, replacing imported high-efficiency desulphurizer, adding alkali scrubber after absorption tower, and changing waste gas from liquid sulphur tank into reactor treatment.The SO 2 mass concentration of exhaust gas is far lower than the limit of 100 mg/m ^3 of Standards for emission of pollutants from petroleum refining industry GB 31570-2015.
