浮顶罐储存煤油的经济分析
Economic analysis on floating roof kerosene tank
-
摘要: 通常情况下, 很少用内浮顶罐储存煤油。提出了用内浮顶罐装煤油的设想, 分别给出了立式拱顶罐和内浮顶油罐“大、小呼吸”损耗经验计算公式, 并对内浮顶罐和拱顶罐装煤油时的蒸发损耗量以及两种油罐的造价等进行了对比计算, 认为用内浮顶罐储存煤油是经济、合理和安全的, 建议新建煤油储罐时应采用浮顶油罐。Abstract: Kerosene is rarely stored in inner floating roof tank in general condition. Points out a tentative plan to storage kerosene with inner floating roof tank and gives experience calculation formulae of "big breathing, breathing" losses in vertical dome roof tank and inner floating roof oil tank. Comparison calculation is carried out on volume of evaporation loss in inner floating roof oil tank and vertical dome roof tank for kerosene storage and the cost of the two kind of oil tanks. It is considered that storage of kerosene with inner floating roof tank is economic, reasonable and safe. It also proposes that newly-build kerosene tank should be of floating roof type.
