Analysis of the high methanol content in polypropylene and solutions?
Thread Content
As the title suggests, in both coal-based chemical industries and petroleum-based chemical industries, methanol levels in polypropylene can be high. Let’s discuss the reasons for this and what solutions can be adopted
It seems no one is concerned about this issue; everyone’s polypropylene is of good quality
It is the high methanol content in propylene; to increase the conversion rate, is a chiller added upstream? Sometimes, when the water content in the reaction medium is high, ice forms in the chiller, and methanol is injected to dissolve it. 1. Add a methanol wash tower or a packed tower at the purification stage

Yes, freezing won’t be an issue; to be precise, it’s probably the poor flow of material – methanol needs to be used to clear things up :)
