We can see if low-pressure separation can be used.
Could you explain in detail the “method of low-pressure separation”? ?
It is recommended that the original poster read up on the technology related to the separation stage of DuPont-process polyethylene produced at Fushun Ethylene; they use hexane as a solvent, and referring to their process could be instructive.
I can also learn* here and make progress
Hello! Thank you! Where can I find relevant materials?
It is recommended that you go and investigate these details at the relevant companies.
What method does the poster want? Are there many kinds? Also, you can look up a book titled \"Principles of Polyethylene Production.\" I’ve attached a flowchart here that you can use as a reference……
Hello, thank you for your suggestion. Initially, it is planned to cool and precipitate the material first, then filter it into polyethylene residue with less than 30% solvent content, and finally granulate it using a twin-screw devolatilization machine. The main issue now is what method to use for cooling
