| 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 （VOCs） 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 VOCs 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 VOCs， and reduce the diffusion of the pollutant during daily production management in order to minimize the impact on surrounding environment. |
