Molten sulfur loading facility with automatic system

Do you degas your sulfur before sending it to the loading facility?

I've heard the same kind of troubles like that where I work...
I can't give you the solution, but if I remember well, they was talking about changing the tool for connecting the truck and to insert a kind of gaz in the truck for keeping the H2S in the truck...

I don't remember the name, but a plant in Alberta use that kind of connection... maybe you could search who load and un-load in Alberta that stuff and ask them how they do... It doesn't exist many plant who makes that.

Two ways to handle this.
1. degas the sulfur before loading.
2. use a vent hood with a vacuum eductor to handle any offgas from the truck.
We use the latter method. All gas/vapor is routed to an incinerator. We have small port in the hood that may be used to check liquid levels in the truck.

You can put weighing devices on the suspension of the truck/trailer that would give you a weight indication of when the rig was loaded. Or, load on a set of scales. Many types of bulk solids are loaded thusly.

could you measure the weight of the tanker prior to start of filling operation and then calculate how much mass of sulphur is needed to fill the truck and then stop at the right momen?

1906, below are my views on sulphur loading facilities:

- In newer facilities the suphur is degassed.
- Locate the loader upwind of the truck hatch.
- Make sure the guard rails are good. Most deaths are due to falling after the loader is overcome by H2S.
- In our old systems, the loader looks and manually stop loading.
- In the newer systems, the level device automatically stop loading a few inches below the top.
- In the newer systems the vapor is recovered and routed through an ejector to the incinerator.
- This all being said, the old simple system works much, much better than the newer systems.
- The new loading arms are difficult to move and the vapor recovery piping and systems doesn't work well. Maybe a design issue.
- I recommend you contact a company that specializes in sulphur handling/loading, and go and look at the system they propose. There are a couple of such companies in Alberta.
