In order to further explore the characteristics of VOC emissions from chemical enterprises,five large chemical enterprises in a certain fine chemical park were selected as research objects.Relevant data were obtained through sample collection and gas chromatography analysis,and the temporal and spatial distribution patterns of VOC emissions were explored.The results show that VOCs are more likely to accumulate in the downwind direction due to aerodynamic effects,resulting in higher concentrations.Meanwhile,the VOCs in the morning and evening are significantly higher,with the main VOCs being olefins and aromatics.The analysis results can provide certain reference and guidance for subsequent VOC governance work.
