An external floating roof tank is a storage tank commonly used to store large quantities of petroleum products such as crude oil or condensate. It consists of an open- topped cylindrical steel shell equipped with a roof that floats on the surface of the stored liquid. The roof rises and falls with the liquid level in the tank. [1]
They are essentially cone-roof tanks with an internal floating roof travelling vertically up and down along with the liquid level. This floating roof traps the vapour from low flash-point fuels. Floating roofs are supported with legs or cables on which they rest. FR tanks do not have a fixed roof, being open at the top, and have a floating roof ...
Fixed roof tank. A fixed roof tank is a type of storage tank, used to store liquids, consisting of a cone- or dome-shaped roof that is permanently affixed to a cylindrical shell. Newer storage tanks are typically fully welded and designed to be both liquid- and vapor-tight. Older tanks, however, are often riveted or bolted, and are not vapor tight.
LNG storage tanks can be found in ground, above ground or in LNG carriers. The common characteristic of LNG Storage tanks is the ability to store LNG at the very low temperature of -162 °C (-260 °F). LNG storage tanks have double containers, where the inner contains LNG and the outer container contains insulation materials.
The storage tanks at an oil terminal may include fixed roof tanks, internal floating roof tanks [10] and external floating roof tanks. [1] Floating roof tanks are generally used for more volatile products to reduce evaporation loss. Fixed roof tanks have a vapor space above the product, which breathes in or out as the product is removed or the ...
Ten 2,500m 3 and 6500m 3 floating roof tanks used for the storage of finished grade petrol and kerosene; The LPG (liquefied petroleum gas) storage spheres were about 450m away from the nearest refinery unit and about 300 m (1,000 feet) from the nearest houses in the village.
