Sulfur vaporization
Sulfur vaporization
(OP)
Dear all,
we are designing a small unit where we should vaporizein continuous a small amount of molten sulfur.
We have some concern due to the viscosity change of molten S (increase then decrease) so do you have any suggestion on the typeof "boiler" to be designed? We will appreciate any typeof suggestion.
thanks
Francesco

RE: Sulfur vaporization
The unusual cyclooctasulfur S8 liquid viscosity rises with temperature by ring cleavage and formation of catenasulfur species above about 160oC and reaches a maximum somewhere about 200oC and thereafter falls on heating until at the b.p. of 444.6oC becomes again a mobile dark red liquid.
RE: Sulfur vaporization
I was in fact thinkinhg if it can be better to flow the molten sulfur inside a tube heat exchanger in a gas fired chamber or if it was better to keep sulfur in a "kettle" type boiler with gas firing inside the tubes submerged...
any idea or suggestion?
