Maximum height of the floating roof in the methanol storage tank
Thread Content
It is a internal floating roof methanol storage tank with a designed capacity of 20,000 m3 and a designed height of 17.5 meters. According to the relevant standards, the installation height of an internal floating roof must be no less than 1.8 meters; however, there is no requirement regarding the maximum height. Can it be assumed that this maximum height is equivalent to the designed height of the tank? I would appreciate some guidance from the more experienced members of this forum.
The maximum height of the internal floating roof generally does not exceed the designed height of the tank. The safe operating space and the maximum allowable liquid level height should also be considered during design. The specific figures need to be determined in accordance with design specifications and actual operational requirements. .
The maximum height of the internal floating roof shall not exceed the design height of the medium it contains.
There must be some margin left on the floating disk; in practice, the liquid level never reaches that high, so there’s no need to worry
Storage capacity also needs to be taken into account; the maximum storage volume in hazardous chemicals storage tanks must not exceed 80% of their total capacity
The height of the floating disk itself also needs to be taken into account. Large tanks generally use a single-disc design; therefore, it is necessary for the floating disk manufacturer to provide information on its height in advance. Additionally, since foam is used in the storage tank, the height of the foam outlet must also be considered.
