Sulfur Blocks Melting Plant 1

[Yuze]

Currently we have sulfur blocks stacked on plant site. We are planning to built a permanent sulfur melting plant. The sulfur came from Claus process and approximately contained 10 ppm H2S before the block was formed. The plant capacity is about 1000T/d. the melted sulfur will be trucked out for sale. Steam will be used for melting. A small boiler may be required to produce the steam required.

Anyone knows proper technology or facility available for this purpose? What are the main challenges for this kind facility?

Thanks,

Yuze

We did this at a plant I worked at years ago. Dont remember much except that good filtration of the melted suplhur was critical. You would be surprised what was picked up in the blocks as they were originaly laid down.

I used to use an Ellithorpe remelter that was essentially a vertical truck bed of steam coils that pressed against the coil.

The resulting liquid sulphur flowed down into a series of troughs and then into a heated sump for pumping and storage. I was forever getting sulphur burns from spattering sulphur, the stench was horrific, and small sulphur fires were not uncommon. I was quite happy when that job ended.

Suggest you talk with one of the big sulphur movement companies...

Thanks for your replies. We have considered using the steam coil pressed against the sulphur blocks. However, there are a few disadvantage for this option.
1, our sulphur block is about 100 feet. Using the steam coil pressing against it needs to be step by step.
2, In the winter, the weather is very cold the heat loss for the steam coil may be quite significant and the productivity may be low.
3, Since this is a permanent facility and the design life span is for 25 years, the reliability for the steam coil may not meet the life span requirement.
