Floating Roof Tank Vs Fixed Roof

For one of our projects in india.

Floating roof tank vs fixed roof.

Floating roof tank allow the explosive gases in petroleum tanks to vent to atmosphere in a safe way. It consists of an open topped cylindrical steel shell equipped with a roof that floats on the surface of the stored liquid. An internal floating roof tank is a floating roof tank fixed an extra fixed roof on the floating roof to prevent floating roof from wind and rain and guarantee the quality of the stored oil. As with the internal floating roof tanks the function of the fixed roof is not to act as a vapor barrier but to block the wind.

Domed external floating roof tanks usually result from retrofitting an external floating roof tank with a fixed roof. We have requirement for storage of high speed diesel for which we have selected 33 m dia x 17 5 m of 3nos. Storagetech storage tank internal floating roofs storagetech has been proudly innovating designing manufactiring and installing external and internal pon. An external floating roof tank is a storage tank commonly used to store large quantities of petroleum products such as crude oil or condensate.

Internal floating roof tank can be used to store gasoline jet fuel and other volatile oil and liquid chemicals like aldehydes alcohols methanol ethanol ketones acetone benzene benzene toluene xylene styrene. Floating roof tanks are generally about twice as expensive to construct as fixed roof tanks so there is a trade off of risk against cost. Today controlled gas venting in to the atmosphere is becoming more and more important due to environmental regulations. The roof rises and falls with the liquid level in the tank.

Various aspects of the floating roof tank working like the operation. The type of fixed roof most commonly used is a self supporting aluminum dome roof which is of. Floating roofs have been designed and used for more than a century. Perfect designed internal floating roof storage tank is the best method to control the evaporation loss of the fixed roof tank.

Floating roof tanks vs fixed roof tanks what are the main factors to choose floating roof tanks over fixed roof tanks. However by reducing emissions the increased costs can be offset or justified on the basis of reduced product loss though evaporation a product savings and less impact to the environment.
