摘要
Abstract
To address ozone(O3)pollution caused by fugitive volatile organic compound(VOC)emissions from typical process stations in the oilfield extraction industry,VOC concentrations from key emission sources were systematically quantified and their concentration distribution characteristics were statistically analyzed.The ozone formation potential(OFP)of individual components was then calculated using the Maximum Incremental Reactivity(MIR)and Propylene Equivalent Concentration(PEC)methods to inform strategies for reducing oil loss and controlling O3.The results showed that among various emission sources,VOCs from storage tank emissions exhibited the widest concentration range and the highest median(55 750 mg·m-3),followed by fugitive emissions from the produced water treatment process(median:909 mg·m-3).Elevated leak concentrations from dynamic and static seals were primarily found at well fields and pressurization points,where flanges and valves were the dominant leak types.Compositional analysis revealed that alkanes were the predominant group in VOCs from both storage tank volatile losses and the produced water treatment emissions,yet the latter exhibited significantly higher mass concentrations of aldehydes,ketones,and alkenes.Consequently,the OFP per unit VOC concentration(μg·m-3)from the produced water treatment process was approximately 1.5 times that from storage tank emissions.This study demonstrates that implementing stringent controls on storage tank VOC emissions and enhancing environmental regulation of fugitive emissions from the produced water treatment process are critical measures for reducing total VOC emissions and mitigating O3 formation potential in the oilfield extraction industry.关键词
