Abstract：In this study, the VOCs emission factor, composition spectrum and ozone generation contribution of rapeseed vegetable oil and soybean vegetable oil processing industries were studied, and the national VOCs emissions of the industry were also calculated. Results show that the processing VOCs emission factor was 1.20kg per ton of rapeseed, 6.32kg per ton of rapeseed oil, 0.36kg per ton of soybeans, and 2.35g per ton of soybean vegetable oil. The VOCs species emitted from rapeseed oil processing and soybean oil processing were mainly from the volatilization of organic solvents. The VOCs species with the largest proportion of VOCs emissions were n-hexane, followed by methylpentane (including 3-methylpentane and 2-methylpentane), and then methylcyclopentane. The OFP in the vegetable oil processing industry was 931.47μg/m3, of which alkanes contributed 61.90%, followed by olefins (19.61%) and OVOCs (15.14%). In 2019, the total VOCs emissions from China's soybean and rapeseed edible vegetable oil processing were 51200 tons, contributing 65.4% and 34.6%, respectively. Of the total emission, 72% came from Shandong, Hubei, Jiangsu, Guangdong, Henan, Guangxi, Tianjin, Hebei, Hunan, and Fujian together.
