Can the salts in alcohol be filtered out through a filter?
Thread Content
In this process, the acidic alcohol, after being neutralized, contains a large amount of salts. I am considering installing a multi-pocket filter, a bag-type filter medium – will it be possible to remove these salts?
Salt cannot be filtered out, as it is completely dissolved in alcohol.
The original poster might be referring to the crystalline salts that have already formed, but the fact that such a large amount of salt is produced suggests there could be some issues with the design of this process.
Yes, there is a defect in the manufacturing process, and it cannot be resolved at the moment
This depends on the size and density of the precipitated salt crystal particles, in order to select the appropriate filter material and filtration pore size. For some salts, the crystals that precipitate tend to form particles of large size, making it easy to choose the appropriate filter material and filtration pore size. However, for some salts, the crystals are extremely fine and prone to caking, which poses significant challenges.
It’s the small type; the filter is almost installed now. We’ll see how it performs later
The centrifuge is used to separate the salt out through filtration.
There is still salt in the alcohol, and it’s likely difficult to deal with this issue. Could a sedimentation tank be added to the processing process? If low temperatures are necessary, cold water can be circulated through internal jackets or coils; the material should flow in at the bottom and out at the top, with the salt being removed regularly；
Why not use evaporation crystallization?
Filtering can address the issue of salt particles, but it cannot completely remove salt, unless the alcohol is completely free of water. .
