Abstract: Volatile organic compounds(VOCs) are important precursors of air pollutants,especially PM2.5 and O3,which not only damage the environment,but also threaten human health. China is the largest country of producing coke and the coke output reached 438 million tons in 2018. Great attention has been paid to the treatment of pollutants produced in this production process. And after comprehensive treatment in recent years,the treatment of pollutants has gradually transitioned from conventional pollutants to unconventional pollutants,and from organized emissions(sulfur,nitrogen compounds) to unorganized emissions(VOCs,NH3). Therefore,as a typical representative of unconventional pollutants in the coking industry,it is great significant to study the integration characteristics of their emission characteristics and treatment of VOCs. In this paper,the VOCs emission nodes in coking process were described in detail,and it was pointed out that the chemical recovery and tar processing are the key processes of VOCs emission. According to the principle of production and the form of emission,the emission modes of VOCs were classified. The exhaust gas properties and total emission calculation methods of each section were further summarized and compared,and the four characteristics of VOCs emission in coking industry were clarified:many emission nodes,great difference,complex components,heavy odor. Based on the study of emission characteristics,the possibility and development trend of application of various treatment technologies in coking industry were analyzed from two aspects of with/without organization,and the basis for selecting the best applicable technology for pollution control was given. Finally,taking the VOCs treatment technologies of TISCO coking and Shaanxi Heimao coking as examples,the two application of VOCs treatment technologies in coking plant were introduced and the VOCs emission characteristics of coking industry in depth were analyzed,which provided scientific and reliable technical support for the formulation of VOCs control strategy of coking industry based on improving air quality.
