Negative pressure distillation, seeking advice
Thread Content
Teachers can add me; there are many things I don’t understand
It’s best to discuss this topic with a process flow diagram; it’s easier to understand things when looking at the diagram. As for whether the pressure in the tower is positive or negative, it doesn’t matter; what’s important is to understand the mass and heat transfer relationship between the rising gas and the liquid stream flowing downward. All other auxiliary equipment serves it. This is a big goal.
In principle, it’s the same whether it’s positive pressure or negative pressure! For negative pressure, other auxiliary equipment is required to maintain a constant negative pressure level (such as vacuum pumps), and for some positive pressures as well, inert gases may need to be added to keep the positive pressure at the desired level. As mentioned above, if you have questions, they need to be more specific; otherwise it’s difficult to analyze!
It’s not appropriate to ask others to add you and keep asking questions of you in this way. Raise your questions if you have any; otherwise, only those who are willing to answer questions will take the initiative to add you.

No, thank you. I’ve already submitted my resignation; I’m not qualified for management roles, and they won’t let me handle operational tasks either
There are many ways of distillation; the principle is the same in all cases, with only differences in the methods of implementation. Information on this topic can be found online for study*.
Your movement skills are amazing. . . . Distillation likely refers to a tower in a factory. If you are a new employee and want to pursue a management role, you should first learn the technical aspects; once you have the skills and experience, then focus on operating the equipment. There must be a reason why operations aren’t allowed; so first, learn from the experienced workers. Then I resigned{:3_69:}
