汽油氧化脱硫醇尾气冷凝-蓄热燃烧技术

Condensation-regenerative thermal oxidation technology for treating tail gas from gasoline sweetening unit

汽油氧化脱硫醇尾气中含有氧气、氮气、水蒸气和油气,油气体积分数为20%～40%。2007年中国石油化工股份有限公司沧州分公司将抚顺石油化工研究院(FRIPP)的冷凝-蓄热燃烧技术成功应用于一套尾气处理量150m^3/h的工业装置上。在0～5℃,尾气中的大部分水蒸气凝结成水;在-60～-70℃,85%～90%油气冷凝成液体;油气体积分数为2%～5%的不凝气用空气稀释到0.2%～0.6%,进入蓄热燃烧装置处理,净化气体符合中国《大气污染物综合排放标准》(GB 16297—1996)和《恶臭污染物排放标准》(GB 14554—93),非甲烷总烃浓度小于120 mg/m^3。

The tail gas from gasoline sweetening unit contains oxygen,nitrogen,water vapor and oil vapor which are of 20v%～40v%concentration.In 2007,the proprietary condensation-regenerative thermal oxida- tion(TRO) process licensed by FRIPP(Fushun Research Institute of Petroleum and Petrochemicals) was successfully applied in the commercial unit with a capacity of 150 m～3/h of tail gas in SINOPEC Cangzhou Company. In the condensation process,most of vapor is condensed to water at 0～5℃,and 85%～90%of oil vapor is conde...
