中文摘要:
      采用苏玛罐采样-超低温预浓缩气相色谱质谱联用方法,开展油田特征VOCs成分的分析工作。通过对某油田生产开发区及周边环境敏感区环境空气的持续监测,发现油田特征VOCs的整体扩散规律,低温、温度骤降以及高湿度环境极不利于VOCs扩散,对特征VOCs成分解析并核算其光化学反应特征,明确了臭氧生成潜势,研究表明烷烃及苯系物对臭氧生成的贡献较大,两者的贡献占比达到70%,初步明确了其对周边环境的影响状况。
英文摘要:
      The characteristic VOCs components of the oil field were analyzed by suma sampling-ultra-low temperature preconcentration gas chromatography-mass spectrometry, which has the characteristics of high sensitivity and multiple effetive detection. Through the continuous monitoring of the ambient air in the production development zone of an oil field and its surrounding sensitive environmental areas, it was confirmed that low temperature, a sudden drop in temperature and high humidity were not conductive to VOCs diffusion. The characteristic VOCs components were analyzed and their photochemical reaction characteristics were calculated, which clarified the potential of ozone formation. The results showed that alkanes and benzenes contributed a lot to ozone formation, the contribution of both was 70%, the effect of VOCs on the surrounding environment was preliminarily defined.
