乙烯厂汽油加氢装置烧焦尾气VOCs治理实践浅析

Analysis on VOCs Treatment Practice of Singed Exhaust Gas of Gasoline Hydrogenation Unit in Vinyl Plant

乙烯厂的汽油加氢装置烧焦尾气中含有烃类等VOCs,硫化氢、二氧化硫、三氧化硫等有毒有害物质,成分复杂,直接排放至大气会引起严重的环境污染;治理过程中要根据实际情况进行治理设备的选择,北京乐文科技发展有限公司设计的此套VOCs治理工艺经过在兰州石化乙烯厂汽油加氢装置的实际应用,起到了良好的效果,有效降低了VOCs等有毒有害气体的排放量,本文主要介绍了VOCs治理设备应用情况及改进意见。

The burning tail gas of gasoline hydrogenation unit in vinyl factory contains VOCs such as hydrocarbons,hydrogen sulfide,sulfur dioxide,sulfur trioxide and other toxic and harmful substances,the composition is complex,directly discharged to the atmosphere will cause serious environmental pollution;In the process of management,we should choose the management equipment according to the actual situation.The VOCs management process designed by Beijing Lewen Technology Development Co.,Ltd.has played a good role in the practical application of the gasoline hydrogenation unit in Lanzhou Petrochemical ethylene plant,which effectively reduces the emissions of VOCs and other toxic and harmful gases.This paper mainly introduces the VOCs management equipment application and improvement suggestions.
