Regarding the distillation column issue
Thread Content
After a line is taken out from the distillation column, it returns to the column; there is also a Venturi tube connected in between. What is the purpose of this line? It starts from plate 51 and returns directly to plate 52 without any heat exchange process. What is the purpose of this pipeline? (Not product extraction, nor intermediate reflux)
Could you tell me what kind of fractional distillation tower it is?
It is guessed that a substance similar to a corrosion inhibitor should be injected.
It is not filled with a corrosion inhibitor. It’s just a pipeline that runs out of the tower and then back into it. A venturi tube is connected in the middle.
