An industrial volatile organic compounds (VOCs) emission inventory was developed in China in 2018. It was based on the emission factors method, using a revised and updated source classification system and emission factors of key industrial sources. Results showed that the total industrial VOCs emission in China in 2018 reached as high as 12698 kt. Processes using products containing VOCs were the largest contributors, accounting for 59% of the total emission. The industrial coating industry, printing, the basic organic chemical industry, gasoline storage and transport, and the oil refinery industry were the five largest emitters, accounting for 54% of the total emission. Guangdong, Shandong, Zhejiang, and Jiangsu were the four largest emission contributors, contributing to 41% of the total emission. Hainan, Ningxia, Tibet, Heilongjiang, and Xinjiang showed the largest VOCs emission intensities, with more than 80 t·(100 million yuan). Processes using products containing VOCs were the main emission contributors in most provinces. The uncertainty for the total industrial VOCs emission in 2018, based on a Monte Carlo simulation, was[-32%, 48%] at the 95% confidence interval.
2018年中国编制了一份工业挥发性有机化合物(VOCs)排放清单。该清单基于排放因子法,采用了修订和更新后的源分类系统以及重点工业源的排放因子。结果表明,2018年中国工业VOCs排放总量高达12698千吨。使用含VOCs产品的工艺是最大排放源,占总排放量的59%。工业涂装行业、印刷业、基础有机化学工业、汽油储存和运输业以及炼油行业是五大排放源,占总排放量的54%。广东、山东、浙江和江苏是四大排放贡献省份,占总排放量的41%。海南、宁夏、西藏、黑龙江和新疆的VOCs排放强度最高,超过80吨·(百万元)。使用含VOCs产品的工艺是大多数省份的主要排放源。基于蒙特卡洛模拟,2018年工业VOCs排放总量在95%置信区间的不确定性为[-32%,48%]。
