Distance between the liquefied gas tank and its associated pump room
Thread Content
What does the distance between the liquefied gas tank and its associated pump room refer to, from where to where? Should it be calculated at the outermost edge of the horizontal projection of the spherical tank, or at the actual outermost edge of the tank? Because the spherical tanks are elevated, with a certain distance from the ground. The distance calculated from the outermost edge of the actual spherical tank is greater than the distance calculated from the outermost edge of its horizontal projection.
Generally, the spacing dimensions indicated on the general plan are planar dimensions, that is, the spacing dimensions on the projection plane. As long as the spacing dimensions on the drawing are not less than the fire protection spacing specified in the standards, there is no problem. If the spacing shown on the drawings is less than the fire safety spacing requirements, then even if the actual spatial distance meets the specified requirements, the drawings will still be considered non-compliant.
I agree with what was said above, but tables 4.1.10 and 4.1.11 in the code clearly state that it refers to the calculation of the external wall of the storage tank； There is a risk in this. If the storage tank is built taller and a pump is placed at the bottom, it will meet the specifications ； Obviously not appropriate!

If it is a dedicated pump area for tank groups, should it be arranged in accordance with the provisions of Article 5.3.5? Additionally, do pumps (rooms) A and B in the tank area listed in Table 4.2.12 refer to pumps (rooms) that serve the entire plant? Otherwise, the rules would be contradictory! For example: according to 4.2.12, the distance between the pump and the spherical tank (1000 cubic meters) is 30 meters, while according to 5.3.5 it is 15 meters.
