faint! Why does crude methanol turn white?
Thread Content
The refined methanol in our factory is colorless and transparent, but a few cars of crude alcohol brought in from outside a few days ago were found to be milky white. The cars had been loaded with other things but they were confirmed to be cleaned. These cars of alcohol were brought from our new 300,000-ton synthetic ammonia branch plant. Is it because the equipment of the new plant was not cleaned? Or is it because the water in the pipe has not been blown out? faint!
Dispersion (emulsification) occurs when there are slight impurities (oily). This is common in the ethanol industry.
This kind of phenomenon usually doesn't happen, maybe it's paraffin.
It must be that the library can apply for profit transfer or return. Because the methanol wax is attached to the wall of the container and the upper part of the leaves, there must be more reservoir base.
Need to do some analysis! Don’t jump to conclusions blindly! Whether the methanol truck is really thoroughly cleaned needs to be verified, and the cleaning agent must also be verified! The supplier needs to verify that there may be wax formation in the crude methanol, which will lead to the situation described by the original poster!
It is caused by wax formation during the synthesis of methanol.
It belongs to the fusel oil series substances. During the transportation process, the oily substance mixes with the water in the crude alcohol to form a milky white substance! ! :handshake:handshake
I saw so many people upstairs insisting that it was caused by paraffin, but I personally feel that this is not necessarily the only cause.: One may be caused by paraffin ； The second is that the fusel oil content is too high. These paraffin or fusel oils will appear milky after being transported for a long time. But I don’t think the possibility of the problem of washing after washing mentioned by the brother on the 6th floor is very unlikely. After all, even if there is residue after washing, it is only a small part, and this phenomenon will not occur.
Thanks to everyone above for your help. After it was transported to the third car, it no longer turned white, but I still don’t know why.
:) It may be that the alcohol in the previous car has unstable water solubility, which is a quality issue. Maybe the tanker has not been cleaned properly, but in the future, pay more attention to the standard indicators of high-quality refined alcohol, and it will be easy to find out after an analysis!
My humble opinion, for reference only: I just read your post again and found that you said that the crude methanol was brought from the "newly built 300,000-ton ammonia branch plant." Did your ammonia just start production? The fusel oil content in the crude methanol will be high when the car is first started, but after the system stabilizes, the fusel oil content will decrease and stabilize, so the crude methanol will no longer be milky white in the third car.
