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. |
