一、前言石油及其产品在储存过程中的蒸发损失是相当惊人的。在北京地区,一台储存汽油的3000米~3拱顶油罐,如果一年进出油操作150次,则一年的汽油蒸发损失量高达200吨左右,对全国的油罐来说,各类油品在储存中的蒸发损失量就可想而知了。油品的蒸发损失不仅使宝贵的能源白白浪费,油品质量下降,从而造成巨大的经济损失,而且还严重污染环境,危害人们的健康,并且导致油罐操作安全性的降低(火灾危险性增加)。为了减少油品蒸发损失,节约能源,在70年代北京设计院开发了钢盘式内浮顶油罐技术,并设计了公称容量100米~3至10000米~3。钢盘式内浮顶油罐系列。从70年代至今,钢
I. INTRODUCTION The evaporation loss of petroleum and its products during storage is quite striking. In Beijing, a storage of 3,000 to 3 vaults of gasoline tank, if the oil into operation 150 times a year, then the loss of gasoline evaporation of up to 200 tons a year, the country’s oil tanks, all kinds The loss of oil evaporation in storage can be imagined. Evaporation losses of oil products not only waste valuable energy, but also reduce the quality of oil products, resulting in huge economic losses. They also seriously pollute the environment, endanger people’s health, and reduce the safety of operation of the oil tank (increased fire risk ). In order to reduce the loss of oil evaporation and save energy, the Beijing Institute of Design developed the steel floating roof tank technology in the 1970s and designed a nominal capacity of 100 to 3 to 10,000 meters. Steel disc floating roof tank series. From the 70’s to the present, steel
