How is the floor area of a spherical tank calculated?
Thread Content
How should one calculate the floor area of a lobe-type spherical tank with a nominal volume of 5,000 cubic units and 14 support columns?
I think it is the circular area of the sphere’s diameter, that is, the projected area.
If planning the land use, the issue of land requiring a safety distance also needs to be taken into account. If a flare is planned to be installed, the safety distance can be considered as 0.5 times the diameter; if no flare is planned, the safety distance is one diameter.
Agree with the second floor. Several considerations: 1. Sphere projection (whether to include accessories such as ladders, etc.), 2. Area occupied by the footings, 3. Area of the anti-escape bund, 4. Regulatory safety distances.
For a standard 5,000-cubic-meter spherical tank with a diameter of 21,200 mm, the required distance from surrounding buildings is determined based on the properties of the medium and the regulations set out in petrochemical or construction standards; this will then allow the required land area to be determined.
