Above ground molten sulfur tank heating
Above ground molten sulfur tank heating
(OP)
Hi everyone,
Do you know some industry using external steam pad heating system on above ground molten sulfur storage tank ?
We are considering using such a heating system but we would like to know if such a technology is efficient enough for this application.
Our tank is 55 ft dia. 30 ft high and the temperature to maintain inside the tank is 290°F. Our lowest ambient temperature is -20°F.
Thanks

Most of the AG tanks I have encountered have been horizontal tanks on saddles. Multiple steam heaters are inserted into the tank end.
This, of course limits the workable volume

Periodic cleanout of the tank should be a significant consideration. Perhaps additional manways may be required.

You may have luck with a centrifugal pump if you can keep things hot, However, consider the specification of a robust PD pump for transfer such as the Viking rotary pump line
I also found out a lot more about sulfur on this link..

Know that one company TPA (part of CBI nowdays) recommended the use of external heating for some applications. see http://www.cbi.com
Used such a solution for the sulphur recivever/degassing vessel out of the SRU's bit not for the receiveing tank (this one was equipped with regular steam coils if I remember this correctly).
I guess it all comes down to if you can provide the necessary heat transfer, i.e. that the tank is small enough.

My recommendation is to use heat coils inserted through the roof of the tank. If there is a leak in one of the bundles, it can be extracted from the tank without needing to drain the tank to effect repairs.
