Economic analysis on floating roof kerosene tank

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.
