Abstract: The coal chemical industry is a typical emission industry of volatile organic compounds( VOCs),involving chemical processes such as gasification,liquefaction,coking,and low-temperature pyrolysis. With the in-depth promotion of VOCs emission reduction action in China,the comprehensive treatment of VOCs exhaust gas from the coal chemical industry has been widely concerned. By analyzing the emission sources and emission characteristics of VOCs in the coal chemical industry and the advantages and disadvantages of mainstream VOCs treatment technologies,some targeted suggestions of VOCs treatment technology were given. According to the differences in the main emission sources and emission characteristics of VOCs in the coal-to-gas and coal-to-coking industries,suggestions on VOCs treatment technology were given respectively. By summarizing the technological research progress and the actual industrial application situation,the future research direction was prospected. At present,the technical system for VOCs emission accounting in the coal chemical industry is imperfect( such as the supplement and adjustment of experience coefficients,localized update of emission coefficients,etc.),the inspection system is imperfect,and the reliability of the test data is insufficient,leading to errors in the accounting results,which seriously affects the fine control of VOCs. Due to the lack of uniform and standardized industry standards,the commonly used " Guidelines for VOCs Pollution in the Petrochemical Industry" is not fully applicable to the coal chemical industry. By optimizing production technology,improving process equipment and strengthening the promotion of LADR technology,the prevention and control of fugitive emission of VOCs should be strictly controlled from the source. The technical performance,economic performance and environmental performance should be considered comprehensively in the treatment of end-point VOCs: VOCs exhaust with recycling value is given priority to use recycling treatment technology,and VOCs exhaust with low recycling value or no recycling value uses destruction treatment technology; single-end treatment technology is difficult to effectively reduce VOCs emissions,and combined technology can achieve higher purification efficiency,effectively reduce secondary pollution and reduce energy consumption. The widely used regenerative catalytic oxidation technology( RCO) has the advantages of strong applicability and good economic benefits,but it is still restricted by the performance of the catalyst. Recently,more and more combined treatment technologies have been proposed and applied,such as adsorption concentration-catalytic combustion,adsorption concentration-regenerative oxidation-adsorption,chemical absorption-photocatalysis-adsorption,chemical absorption-low temperature plasma-photocatalysis,etc. However,the reaction mechanism and interaction of combined governance technologies urgently require to be further studied. For VOCs collection and purification,treatment process,and equipment,coal chemical companies should strengthen fine integrated management,and build a technical system for source control and purification system overall supervision to eliminate human factors.
