装配式铝制内浮顶是新型结构,具有施工安全、方便、安装速度快及抗腐蚀性能好等特点。为确定该内浮顶罐的降低油品蒸发损失效率,采用量气法测定其大呼吸时的蒸发损失量,而小呼吸的损失则按炼油厂的实践积累的经验数据进行计算。测试结果表明,与同容量的拱顶油罐对比降耗率为96.3％。上海炼油厂的5000m~3汽油罐的实践数据,一年可减少蒸发损失为187.88t,折合人民币12.4万元。作者认为:该浮顶罐除具有重大的节能经济效益外,并可减少环境污染及提高操作安全性等社会效益;作为一项新型节能产品应得到大力推广使用。
Assembled aluminum floating roof is a new structure, with construction safety, convenience, fast installation and corrosion resistance, and other characteristics. In order to determine the efficiency of reducing oil evaporation loss of the inner floating roof cans, the amount of evaporation loss during the big breath was measured by the gas method, while the loss of the small breath was calculated according to the accumulated experience data of the refinery. The test results show that compared with the same capacity of the vault tank, the reduction rate is 96.3%. Shanghai refinery 5000m ~ 3 gasoline tank practice data, one year to reduce the evaporation loss of 187.88t, equivalent to 124,000 yuan. The author thinks: In addition to the significant energy-saving economic benefits, the floating roof tank can reduce social pollution such as environmental pollution and improve operational safety. As a new energy-saving product, it should be vigorously promoted and used.
