Refinery tar refining advice
Thread Content
Dear engineers, I have a question. Which process in the refinery produces tar? Can you tell me the specific composition of the tar? Because the mechanical seal comes into contact with the medium, I would like to know which process it is cracked out so that the components can be analyzed. Thank you!
Alas, I am speechless. Haichuan has almost become a data download area, and no one will discuss it! ! ! ! !
It’s not that no one has discussed it, it’s that I really don’t know.
