| 摘要: |
| 2014年青奥会期间，采用苏玛罐采样和GC/MS分析的方法对南京市2家石油化工企业部分典型工艺的特征VOCs进行了监测分析，结果表明，其主要组分为烷烃、苯系物、含氧有机物、卤代烃和烯烃，主要特征污染物有异丁烷、正戊烷、正丁烷、正己烷、正庚烷、正辛烷、苯、甲苯、二甲苯、甲醇、乙醛、丙酮等。指出，企业在日常的生产管理中，应加强巡查、监管，避免装置挥发性有机物的跑冒滴漏，减少污染物的逸散，降低对环境的影响。 |

| Abstract: |
| During the 2014 Youth Olympic Games， characteristic volatile organic compounds （VOC<sub>s</sub>） generated from typical techniques in two petrochemical companies in Nanjing were monitored by sampling with Summa canister and analyzing with GC-MS. The main constitutes included alkanes， BTEX， oxygenated organic compounds， halogenated hydrocarbons and olefin. The main characteristic VOC<sub>s</sub> included isobutane， N pentane， N butane， hexane， N heptane， N octane， benzene， toluene， xylene， methanol， acetaldehyde， acetone， and so on. It was suggested that companies should reinforce inspection and supervision， avoid instrumental leak of VOC<sub>s</sub>， and reduce the diffusion of the pollutant during daily production management in order to minimize the impact on surrounding environment. |
