Floating roof fuel tanks are universally used to store volatile petroleum-based liquids. By design, the floating roof remains in contact with the liquid surface of the fuel and covers almost its whole surface so as to limit the amount of evaporation and emission to the atmosphere. A rim seal around the edge of the tank prevents the always-present vapors from escaping.

voc emissions from external floating roof tanks standard floating roof gasoline storage tank

Since the storage of volatile products in fixed roof tanks would lead to the displacement of vapours in the tank to the atmosphere during tank filling, such products are normally stored in internal or external floating roof tanks which essentially eliminate the vapour space and hence displacement emissions. Why are floating gas storage tanks so popular?Why are floating gas storage tanks so popular?Cost-effectiveness, safety, and efficiency are the main reasons for which these types of storage tanks are highly popular throughout the world. These floating roof storage tanks also help to minimize the amount of vapor between it and the liquid.2 Types of the Roof Storage Tanks in Oil and Gas Industry What's the maximum pressure for a floating roof tank?What's the maximum pressure for a floating roof tank?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.
