Floating Roof Storage Tanks For Crude Oil

In general crude oil storage tank has two kinds fixed roof tank and floating roof tank.

Floating roof storage tanks for crude oil. Floating roof tanks are more ideal for the storage of large quantities of crude oil. It consists of an open topped cylindrical steel shell equipped with a roof that floats on the surface of the stored liquid. Our floating roofs are used by all major oil companies as well as oil storage and pipeline companies because they are safer more cost effective and more environmentally friendly than other floating roof systems. Other systems have a vapour space between the roof and the product allowing dangerous fumes to collect.

Floating roof tanks as compared to fixed roofs pros and cons. Sandborn ifrs are safer because they float directly on top of the product and do not allow vapours to build up. The gases collect in the space that is between the roof and the crude oil. 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 is to be noted that fixed roof tanks could be used for storing low amounts of crude oil as compared to the million barrels stored in floating roof tanks. As the name suggests the floating roof tank consists of a floating roof which falls or rises according to the level of oil in the tank. To prevent the build up of vapor inside the tank the floating roof in this type of tanks has been incorporated as a safety feature. Floating roof tanks are advantageous compared to fixed roof tanks as it prevents vapour emissions that are highly combustible that help eliminate the chances of fire or an internal tank explosion.

Crude oil emits extremely volatile natural gas as well as some air pollutants. While floating roof tank is the optimum selection for storing larger quantities of crude oil. How s crude oil stored. The roof rises and falls with the liquid level in the tank.

A floating roof crude oil storage tank of 100 000 bpd capacity was designed taking into consideration the available geotechnical and meteorological information of the location site. Crude oil storage tanks types. Fixed roof tank is usually used when the quantity of crude oil is not too much. Refiners derived significant advantage through the floating roofs which are used to store very large volumes from super tanker shipments and meet the escalating demand for hydrocarbons in industry.
