Problems in polypropylene production?
Thread Content
I would like to ask professionals familiar with the production of small-molecule polypropylene: is it possible for the catalysts and activators used in the polymerization reaction to end up in the recycling stage?
Yes. Catalysts and activators will enter the recovery section along with the gas.
If the recovery unit has a gas holder, there is no major problem, as this substance is inactivated by water.
Catalysts and activators are mainly introduced into the high-pressure recovery system. Additionally, the most important thing is to look for the reason in the proportions. It’s troublesome to bring it into a high-pressure system. The condenser and some valves are the areas most prone to blockages.
Yes, it depends on what problem you want to solve (that’s why you think of this approach) .
The gas holder in the unit is a dry-type gas holder, and the presence of a catalyst was detected after compression and condensation. I would like to ask how to avoid such problems in production?
We added a cyclone separator to the high-pressure recovery line, and the results are good
