Sulfur Pit Maintenance
Sulfur Pit Maintenance
(OP)
We have a leak in our sulfur pit heating coils. TEG is the heat medium and the leak is in coils, below the liquid/vapor interface.
There was a fire in one of the condesers that caused the TEG to get very hot. Within a week the leaks developed in two of the four heat medium coils.
I plan to use a diaphram pump rated for 350 deg F to pump the sulfur (below the existing pump suction) out of the pit. Any comments?
Would overheating the TEG cause corrosion in the coils. I believe the boiling point of sulfur is over 800 degrees. I doubt that we got that hot, since no one mentioned glowing metal in the heat medium piping!

It is more dangerous when there is a leak.
We use steam as heating medium.
You can extent the shaft of existing sulfur pump to pump out the sulfur in the pit.

The thing you've got to worry about when heating liquid sulfur is the viscosity. Liquid sulfur has an odd viscosity curve. I can't find a very good online source of the curve, but if you look in this PDF file, you can see what it looks like.

Also, here's a little blurb about it found at the following link: http://www.pillard.com/alt_fuels.html
"Liquid sulphur is used as a fuel in all chemical units which produce sulphuric acid from SO2 by combustion. A very particular aspect of liquid sulphur is its viscosity curve : Sulphur comes in liquid form close to 145°C. Then, its viscosity starts to increase from about 157°C and reaches a viscosity of 90 000 centipoises at 190°C. This is why it is necessary to maintain its temperature between specific limits of between 145 and 155°C."
