Abstract: 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.
