Atmospheric and vacuum distillation units, negative pressure issues in vacuum towers
Thread Content
What is the issue with the negative pressure at the bottom of the vacuum distillation tower turning into positive pressure? Is it dangerous? How can it be resolved?
What about the top of the tower? Is the tower top operating normally? If not, there is a problem with the extractor; if it is normal, then the flow rate of the secondary return stream is too high, which may indicate flooding. There will definitely be an impact – the extraction rate is low and the quality of the side products is poor. But all of the above is just guessing\ud83d\ude02
