Discussion on the issue of alcohol leakage in the rectifier tower during alcohol distillation
Thread Content
:) There are several possible reasons for the issue with the fine wine in the tower; I would appreciate guidance from industry experts. Thank you
I’m just starting to work with distillation, so let’s discuss it. I think it is mainly caused by high alcohol content in the feed, large feed volume, high reflux, insufficient preheating temperature, inadequate rising steam, high liquid level in the tower bottom, and unstable feed.
Smuggling liquor? It’s probably due to insufficient condensation capacity; therefore, the reboiler load has to be reduced.
If there is wine leakage from the bottom of the tower, in addition to what was mentioned on the second floor, a low wine extraction rate and an excessive accumulation of wine inside the tower can also lead to leakage.
I’ve been working in the internal operations area for a few months now, and I’ve noticed that even the slightest instability can cause leakage. As soon as water is added to the fermentation tank, the tower starts to rise and then drop again, which also leads to leakage. Ugh, there’s nothing that can be done about it. The laboratory tests are particularly strict.
It hasn’t been stolen and drunk by someone, has it? Those with a high tolerance for alcohol must absolutely avoid going there! :Lol, isn’t the tower pressure too high? If so, more wine will accumulate in the tower, which seems like a case of wine leakage. . .
In my opinion, there are several reasons for wine leakage from the bottom of the tower: First, uneven wine extraction or unstable tower pressure can lead to an excess amount of wine remaining in the tower, causing leakage; however, this issue is easy to identify and resolve； The second reason is poor heat exchange of the vapor at the top of the tower, which leads to pressure buildup at the bottom of the tower, reduced reflux within the tower, lower gas consumption, and a decreased separation capacity of the tower ； The third issue arises from poor separation of fusel oils; the oil layer is dispersed throughout the tower, and may even spread to the bottom of the tower, resulting in wine leakage ； The fourth reason is problems with the tray and other internal components of the tower, which lead to issues in the distribution of alcohol or gas within the tower and result in alcohol leakage; these are my personal opinions.
