摘要
拱顶油罐是石化企业无组织排放源之一。拱顶罐的无组织排放主要是由于油品"大呼吸"损耗和"小呼吸"损耗所引起的。API公式是一种基于实测及理论研究相结合的油品蒸发损耗计算公式,相较于纯理论公式更贴近实际情况,更加准确。因而选取API经验公式作为源强计算公式,计算结果显示"大呼吸"损耗量远远大于"小呼吸"损耗量。以高斯扩散模型为基础,分析了拱顶油罐无组织排放对区域大气环境的影响,提出拱顶罐与油气收集回收工艺以降低油气的无组织排放。
Doom roof tank is one of the fugitive emission sources in petrochemical enterprises. The fugitive emis- sion is caused by oil breathing and working evaporation loss of dome roof tank. The experience formula from A- merican Petroleum Institute （API） was selected to calculate the pollutant source strength. API formula is based on experiment and theoretical studies. It is more accurate. Based on the investigation and evaluation, the extent of atmospheric environmental impact was predicted by Gauss model. Some measures were discussed to reduce the fugitive emission.
