摘要(Abstract):

焦化行业作为煤化工行业的重要组成部分,随着我国VOCs减排行动的持续深入推进,焦化行业VOCs废气的深度综合治理势在必行。笔者简述了焦化行业VOCs废气的来源和组成,以案例形式研究了焦化化产废气和焦化污水处理系统废气的适用治理技术,明确了化产区域冷鼓、脱硫、硫铵工段废气"油洗+水洗+蒸汽加热+焦炉燃烧"治理,粗苯工段废气"负压回收"治理、苯储槽大小呼吸及装车逸散气"深冷冷凝回收+活性炭吸附真空脱附+装车蒸汽平衡"回收技术及污水处理系统废气"酸洗+碱洗+生物滤池+焦炭吸附"治理的工艺路线。焦化VOCs废气的深度综合治理对于提升大气污染防治水平,改善区域大气环境质量意义重大。
Coking industry,as an important part of coal chemical industry,plays an important role in metallurgy,chemical industry and other fields. With the continuous and indepth promotion of VOCs emission reduction action in China,it has become an inevitable trend for the deep comprehensive treatment of VOCs in coking industry. In this paper,the source and composition of VOCs in coking industrywas briefly described. The applicable treatment technology of waste gas from coking production and coking sewage treatment system was discussedin the form ofcase study. The following process route was clarified:the "oil washing + water washing + steam heating + coke oven combustion" treatment of waste gas in cold drum,desulfurization,ammonium sulfate sections of the chemical production area,the "negative pressure recovery" treatment of waste gas in crude benzene section,the "cryogenic condensation recovery + activated carbon adsorption vacuum desorption + loading steam balance" recycling technology for gas exhausted from benzene storage tank size breathing and loading,and the "acid washing + alkaline washing + biofilter + coke adsorption" treatment of waste gas from sewage treatment system.It is of great significance for improving the level of air pollution prevention and improving the quality of regional atmospheric environment by the deep comprehensive treatment of coking VOCs.
