Heating coils & Column supported roof for Liquid sulphur storage tank
Heating coils & Column supported roof for Liquid sulphur storage tank
(OP)
I am handling a Liquid sulphur storage tank (42 m Dia x 9 m Ht) for which operating temperature is 137 deg. C & design pressure is Atmospheric. I have following queries.
1) For above tank, is it adequate to provide heating coils on Tank roof & bottom only ?
OR
Are the coils required on Tank shell also, in addition to tank bottom & roof ?
2) Can I provide column supported roof for this tank ?

#1 -- ?? With sufficient heat input and good insulation, tank bottom only is sufficient.

However,if you have any past experience of Liquid sulphur storage tank with column supported roof, than kindly share the same.

The roof vent will need to be heat-traced to keep sulfur fumes from consension on the flame arrestor grid-plate. And do not try to rum your tank without a vent with a flame arrestor. Flaming sulfur tanks are ugly.

Aggressive interior and exterior corrosion is also a major concern

It is unfortunate that neither the AiCHe not any sulfur producing industry member has developed a guidline for molten sulfur storage and handling.
It is unfortunate that those who are charged with making important (and expensive) design decisions do not have such a guideline to rely upon.
Its not like we haven't been dealing with sulfur for thousands of years...
My opinion only
