Sulphur Tank Foundation_HOT SERVICE
(OP)
I am handling a Liquid sulphur storage tank (42 m Dia x 9 m Ht) whose operating temperature is 150 deg.C.
PWHT for process reason is not required for this tank.
This tank is provided with,
1) Heating coils on Tank Bottom, Shell & Roof.
2) Mineral wool insulation on Tank shell & roof.
I want to know whether any insulation (i.e. Mineral wool, Fire bricks, Refractory castables etc.) is required between Tank bottom & Foundation or not. If required, shall it be covered with all area in contact with bottom plate or it shall be restricted to Ring wall only.
Also kindly clarify that who will decide the bottom insulation requirement (i.e. Civil , Process or Equipment dept.)?

with reference to your reply kindly note that, Our foundation type is concrete Ring wall (Ring width = 500 mm). And the inside slab is made up of compacted sand.
with above configuration, We were proposing the FIRE CLAY BRICKS on Ring wall surface inline with our PTR.
However, Tank vendor has proposed FOAM GLASS HLB on Ring wall surface & this material is also allowed as per hot Insulation specification
Can you suggest, which is the better from both above (FIRE CLAY BRICKS or FOAM GLASS HLB).

Will this be the largest diameter molten sulfur storage tank ever made ?
Where will this tank be installed ?
How will the large theremal expansion movements be considered in the piping design ? Will piping expansion loops be necessary ?
Will there be new and unique thermal expansion problems for this tank because of the extreme design ?
Out of basic respect for the participants in this forum, can you tell us of your final decision on the foundation design and,....perhaps.... submit a detail
Thank You...

I agree with MJCronin that's a pretty big tank, and I'm not sure I like it from the structural standpoint, particularly as relates to this expansion and hold down detail standpoint. You might be better off with several smaller dia. and/or taller tanks for the same total volume. You might even save some heating energy over time, since one tank could be held at process temp. and the others at some lower storage or ready reserve temp.
