摘要获取了菜籽和大豆植物油加工行业VOCs排放系数、成分谱和臭氧生成贡献，并对其全国VOCs排放量进行了计算.结果表明，菜籽油加工过程VOCs排放系数为1.20kg/t菜籽用量和6.32kg/t菜籽油产量，大豆油加工过程VOCs排放系数为0.36kg/t大豆用量和2.35kg/t大豆油产量.菜籽油和大豆油加工排放的VOCs主要来自于有机溶剂挥发.VOCs排放占比最大的物种是正己烷，其次是甲基戊烷（包括3-甲基戊烷和2-甲基戊烷），再次是甲基环戊烷.植物油加工行业OFP为931.47μg/m3，其中，烷烃贡献最大，占比为61.90%；其次是烯烃和OVOCs，占比分别为19.61%和15.14%，.2019年中国大豆和油菜籽植物油加工VOCs排放量为5.12万t，大豆和油菜籽植物油分别贡献65.4%和34.6%，山东、湖北、江苏、广东、河南、广西、天津、河北、湖南、福建是贡献最大的10个省份，合计占比72.0%.服务把本文推荐给朋友加入我的书架加入引用管理器 E-mail AlertRSS作者相关文章孙西勃梁小明廖程浩张永波叶代启关键词：植物油加工, 挥发性有机物, 排放系数, 成分谱, OFP, 排放量 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.Key words：vegetable oil processing volatile organic compounds emission factor composition spectrum OFP emission 收稿日期: 2022-01-20 基金资助:广东省重点领域研发计划项目（2020B1111360003）通讯作者:梁小明,助理研究员,liangxiaoming@scies.org E-mail: liangxiaoming@scies.org作者简介: 孙西勃(1990-),男,河北沧州人,工程师,硕士,主要从事挥发性有机物控制政策研究.发表论文10余篇.引用本文: 孙西勃, 梁小明, 廖程浩, 张永波, 叶代启. 食用植物油加工VOCs排放特征[J]. 中国环境科学, 2022, 42(8): 3610-3615.
