摘　　要：以外浮顶原油储罐为研究对象,采用Tanks4.0.9d模型对储罐挥发性有机物(VOCs)排放特征进行研究。结果表明,外浮顶罐VOCs排放主要来自边缘密封损失和浮盘附件损耗;罐体颜色、内壁锈蚀程度、密封形式、年周转次数、气象参数等均可影响排放量,其中内壁锈蚀程度和密封形式为主要影响因素;采用二次密封可大幅降低排放量,“液体填充+边缘刮板”密封效果最佳;温度和风速与排放量均呈正相关,大气压与排放量呈负相关;通过选择二次密封形式和浅颜色外壁漆面、内壁除锈、罐体隔热保温等措施可有效降低储罐VOCs排放量。The Tanks 4.0.9d model was used to study the emission characteristics and influencing factors of volatile organic compounds(VOCs)from external floating roof crude oil storage tanks.The results showed that the VOCs emissions from the external floating roof tank mainly come from rim-seal loss and deck fitting loss;The influencing factors of paint color/shade,internal shell condition,rim-seal system,turnovers per year,meteorological parameters,all affected the VoC emissions;The internal shell condition,rim-seal system were the main factors affecting VOCs emissions from storage tanks;Using secondary sealing could significantly reduce VOCs emissions,and“liquid-mounted+rim-mounted”had the best effect;The meteorological parameter of temperature and wind speed were positively correlated with VOC emissions,while atmospheric pressure was negatively ed with VOC emissions;By selecting secondary sealing forms and light colored outer wall paint surfaces,regular rust removal on the inner wall of the storage tank,selecting light colored outer wall paint surfaces,and insulation measures for the tank body,VOCs emissions from external floating roof storage tanks can be effectivelyreduced.
