摘要 獲取了菜籽和大豆植物油加工行業(yè)VOCs排放系數(shù)、成分譜和臭氧生成貢獻，并對其全國VOCs排放量進行了計算.結果表明，菜籽油加工過程VOCs排放系數(shù)為1.20kg/t菜籽用量和6.32kg/t菜籽油產量，大豆油加工過程VOCs排放系數(shù)為0.36kg/t大豆用量和2.35kg/t大豆油產量.菜籽油和大豆油加工排放的VOCs主要來自于有機溶劑揮發(fā).VOCs排放占比最大的物種是正己烷，其次是甲基戊烷（包括3-甲基戊烷和2-甲基戊烷），再次是甲基環(huán)戊烷.植物油加工行業(yè)OFP為931.47μg/m3，其中，烷烴貢獻最大，占比為61.90%；其次是烯烴和OVOCs，占比分別為19.61%和15.14%，.2019年中國大豆和油菜籽植物油加工VOCs排放量為5.12萬t，大豆和油菜籽植物油分別貢獻65.4%和34.6%，山東、湖北、江蘇、廣東、河南、廣西、天津、河北、湖南、福建是貢獻最大的10個省份，合計占比72.0%.服務把本文推薦給朋友加入我的書架加入引用管理器 E-mail AlertRSS作者相關文章孫西勃梁小明廖程浩張永波葉代啟關鍵詞 ：植物油加工, 揮發(fā)性有機物, 排放系數(shù), 成分譜, 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     基金資助:廣東省重點領域研發(fā)計劃項目（2020B1111360003）通訊作者:梁小明,助理研究員,liangxiaoming@scies.org    E-mail: liangxiaoming@scies.org作者簡介: 孫西勃(1990-),男,河北滄州人,工程師,碩士,主要從事?lián)]發(fā)性有機物控制政策研究.發(fā)表論文10余篇.引用本文:   孫西勃, 梁小明, 廖程浩, 張永波, 葉代啟. 食用植物油加工VOCs排放特征[J]. 中國環(huán)境科學, 2022, 42(8): 3610-3615.
