Moisture absorption and transportation issues of sulfur powder
Thread Content
Our factory uses the sulfur foam process for acid production; after drying, what remains is sulfur powder. However, in environments with high air humidity, this sulfur powder absorbs moisture quite significantly, and some of it turns into a slurry during transportation. How do people handle this issue when transporting sulfur?
We don’t have this process; please, expert, answer.
The sulfur foam was not washed after filtration; it contained a large amount of salt solution. The sulfur that was dried directly had a high salt content and absorbed moisture from humid air.
I know the principle, I just want to know how to solve it. Currently, belt sealing, tube chain conveyor, and screw conveyor are being used.
You already know and still ask? 1) Wash thoroughly and then dry. It doesn’t absorb moisture no matter how it’s handled, and sulfur can also be sold at a good price ； 2) If washing is not desired, dry it immediately and then bag it to seal it; if bulk transportation is necessary, use dry air for protection.
