Liquid-phase polypropylene: Polishing issues with small loop reactors R200
Thread Content
We need to carry out maintenance work; the walls of our small loop pipes are covered with polymers. We don’t want to send them to Beijing for polishing – what should we do? You can bend pipes by heating them, but what about straight pipes? It was due to the delayed emission last time; as a result, HV223/1 kept getting stuck and required frequent stops for cleaning. So this time during maintenance we want to fix it, but transporting it takes too long and is costly in Beijing time. I wonder if anyone has any good suggestions. My QQ is 46555023 – please share your ideas without holding back; I’m waiting eagerly for advice!
In fact, from a production perspective, it’s not necessary to perform polishing; simply flushing with nitrogen is sufficient. Using blasting is the most effective method! ! ! ! ! ! ! ! ! ! ! !
Our factory disassembles it and cleans it with a water gun
