sulfation roasting
Thread Content
There is a batch of lead-containing materials that need to be sulfated and roasted, with 3-5 tons of material to be processed per day. Steel reactors are considered for this purpose, but they corrode too quickly. How does everyone carry out the sulfation and roasting process? What materials are used to prevent corrosion?
Try an enamel reactor; I’m not sure if it will work
Using a rotary kiln, enamel is definitely not suitable due to the high temperatures. If a small amount of available stainless steel plates are placed in an electric furnace.
I can’t explain it clearly, so I can’t answer you! Which specific lead-containing materials?
Use an iron pot, but it must not be exposed to water – not even the materials used should contain any water. Iron does not react with concentrated sulfuric acid; if dilute sulfuric acid is used, then a titanium alloy should be employed
With a daily processing capacity of 3–5 tons, the use of simple processing methods has a significant impact on the environment; since the temperature during acidification roasting is maintained at around 630°C, the SO2 generated can only be absorbed using alkaline solutions.
Treated centrally in boiling furnaces; a capacity of 3–5 tons per day, which results in low pollution levels
You can use a scrubbing station; since SO2 is heavier than air, spraying it with water mist (and repeating the scrubbing process) allows it to be concentrated if conditions permit, after which it can be used as sulfuric acid
Would it be better to use a tunnel kiln? Titanium is not resistant to high temperatures; it oxidizes severely above 500 degrees.
