一、概述荆门炼油厂氧化沥青装置原设计5万吨/年,近年实际处理量7～8万吨/年.原料为江汉原油的减压渣油(含硫1.5%),主要产品10号沥青.该装置为连续釜式氧化.生产过程中,釜顶尾气量达5000标米~3/时(干尾气).尾气中除含有复杂的氧化物、硫化物、污油粒子外,还含有对人体危害极大的3,4-苯并芘(BaP),含量达200～5000毫微克/米~3.采用高温焚烧法处理这些尾气是防止其污染环境的可行措施. I. Overview Jingmen refinery oxidation asphalt plant designed 50,000 tons / year, the actual handling capacity in recent years, 7 to 80,000 tons / year raw materials for the Jianghan crude oil vacuum residue (1.5% sulfur), the main product No. 10 asphalt The device is a continuous tank oxidation process, the top of the autoclave gas volume up to 5000 standard meters ~ 3 / hour (dry tail gas.) Exhaust in addition to containing complex oxide, sulfide, oil particles, but also contains the right 3,4-Benzo [a] pyrene (BaP), which is extremely harmful to the human body, amounts to 200-5000 ng / m3.3 The use of high temperature incineration to treat these exhaust gases is a viable measure to prevent them from contaminating the environment.
