【I see-62】—So that’s how stripping works

I went to Yanshan Petrochemical Plant and was assigned to the atmospheric and vacuum distillation unit, where there were many stripping processes involved. As a student, and with good grades, I felt confident in myself and tended to be overconfident. When I encountered a stripping tower, I asked the technician who was guiding us there (I now realize that he was also just a college student who knew how to operate valves) what stripping actually entailed. He said it was about using steam to remove certain substances; as for exactly how it worked, I wasn’t brave enough to ask further, and he didn’t explain any more either. . . . (You can see just how pretentious I was at that time :lol) I just used a phrase to deceive myself, without bothering to think about what the principle actually was....... . . A few years later, when I came across the design of atmospheric and vacuum distillation units again, I thought about this matter once more and suddenly understood: stripping is nothing but the application of Dalton’s law of partial pressures in physical chemistry. Thinking back to how high my scores were in physical chemistry exams, I realized that I was only good at theoretical knowledge; I simply couldn’t conceive of such a simple principle back then. . . :Actually, any solvent can be used for stripping; nitrogen works as well too. It’s just that water and hydrocarbons separate easily, which is why steam stripping is used in engineering applications. It seems that there is still a gap between the basic theories in these books and their practical application in engineering; they can’t be applied right away~
Indeed, books are lifeless. Government and enterprises, nitrogen, or low-boiling-point liquids are all acceptable
There's a sense of sudden realization, right? The same thing becomes unclear when different words are used
I vaguely remember that it was mentioned in the book \"Technical Questions and Answers on Atmospheric and Vacuum Distillation Units\". One still needs to read more books. The master might be wrong, but what’s written in books is generally accurate.
I was originally a science student~ I shouldn’t have chosen chemical engineering,, During my university days, I just focused on deriving formulas and didn’t read that many books on oil refining engineering
Well, when we entered the factory, there were many such books in the workshop; they were provided by the factory. For example, there are books such as \"Operators of Atmospheric and Vacuum Distillation Units\" and \"Q&A on Atmospheric and Vacuum Distillation Technology\", as well as materials for junior, intermediate, and senior refinery workers ； It can only be said that your factory doesn’t place much emphasis on employee skill training.
You’re overthinking it; we just go to school to conduct practical training for one week only – in one week, you can only learn a little bit~
Though they have different names, in practice most of them are simplified or replaced with common names instead of scientific names
I learned it; I didn’t know before
