Floating Roof Tanks - an overview | ScienceDirect Topics

Floating Roof Tanks. Floating roof tanks are commonly protected against lightning ignition by bonding the floating roof to the seal shoes at no less than 3m (10ft) intervals, use of insulating sections in the hanging linkages, covering sharp points on hangers with insulating materials, and installation of electrical bond straps across each pinned hanger joint.Fixed or Semi-Fixed Fire Protection Systems for Storage the roof separates and blows off leaving the tank shell intact. This system allows the tank to retain its contents and any resulting fire will involve the full surface of the exposed flammable liquid. Open Top Floating Roof Storage Tank is similar to the cone roof tank in construction but with the exception that it has no fixed roof.

Since a Dome roof is closer to a sphere than a cone the API codes give the designer credit for using a dome as opposed to a cone. In other words we can often build a tank with a Dome roof constructed out of thinner material than a cone.EVAPORATION LOSS MEASUREMENT FROM STORAGE Roof outage - volume contained under a cone roof or dome roof Liquid height Liquid surface temperature Vapor pressure Vent settings Working losses result from the change in liquid level in the tank. When the liquid level increases, the vapor in the tank is compressed increasing the pressure in the tank.
