Design and Study of Floating Roofs for Oil Storage Tanks

The majority of the storage tanks are working under atmospheric pressure. According to API 620 [1] the maximum allowable pressure for storage tanks is 15 psi and if the pressure is larger than this value, it is considered as a pressure vessel. [2] Floating roof tank; as its name; implies the roof to float on liquid surface in the tank. As the liquid level changes due to filling, DIESEL FUELS & DIESEL FUEL SYSTEMSCrude Oil The term crude oil is used to describe petroleum-based oils/fuels that are not yet refined. They are essentially in the same state as when they were pumped from the earth. Certain types of crude oils can be burned in Cat engines.
