Stirring and sealing type for butyl octyl alcohol reaction vessels
Thread Content
I would like to ask everyone: what type of sealing is primarily used for the stirring of the carbonylation reactors in butyl acetate production plants in our country? Is it a mechanical seal or a magnetically driven seal? If a mechanical seal is used, is there any leakage? Could you provide some materials on *studying*? Thank you very much~
Double-end mechanical seal, 53B.

Thank you~ We use magnetic drive currently, and we want to switch to a mechanical seal now~ but we’re worried that it might leak after operating for a short period of time
We use mechanical seals, which are normally replaced every about a year
Magnetic drive, no leaks, long service life – why replace it?
The pressure in the reactor is high, and the process needs to operate continuously. It’s not possible to apply butter to the stirring bearings, and since the lubricant and the medium are miscible with each other, the bearings tend to wear out over time; that’s why replacement is considered necessary.
