沈阳市人为源挥发性有机物排放清单研究

Research on the Anthropogenic Source VOCs Emissions Inventory of Shenyang City

对沈阳市各类人为源VOCs进行分类,收集活动水平数据,应用国内外最新研究成果,采用排放因子法建立了沈阳市2015年人为源VOCs排放清单。结果表明:2015年沈阳市人为源大气VOCs排放总量为13.75万t,其中,化石燃料燃烧源、工艺过程源、移动源、溶剂使用源、生物质燃烧源、储存运输源、废弃物处理源和其它排放源排放量分别占VOCs排放总量的5.35%、55.02%、12.70%、16.51%、8.87%、1.41%、0.24%和0.17%。化学原料和化学品制造业、石油加工、炼焦和核燃料加工业、橡胶和塑料制品业和纺织业为工艺过程源重点排放行业,VOCs排放量占到工艺过程源排放总量的97.16%;表面涂层和其他溶剂使用是溶剂使用源的重点排放行业,VOCs排放量占到溶剂使用源总排放量的81.15%。

Anthropogenic VOCs emissions inventory of Shenyang City in 2015 has been established based on the activity data of different anthropogenic sources and emission factors.The results showed that the total amount of VOCs emissions from anthropogenic sources in Shenyang achieved 137 500 tons in 2015,within which 5.35%、55.02%、12.70%、16.51%、8.87%、1.41%、0.24% and 0.17% were contributed by fuel combustion,industrial processes,moving source,solvent utilization,biomass burning,storage transportation source,waste disposal and other emission sources,respectively.The chemical raw materials and chemical manufacturing,petroleum processing,coking and nuclear fuel processing,rubber and plastic products and cottonocracy were the key emission process that accounted for over 97.16% of the total industrial processes source.The surface coating and other solvents utilization were the key emission process and responsible for 81.15% of the total VOCs emissions of solvent utilization source.
