The disadvantage of delayed recovery is that after the \"dry pot\" condition occurs, (vapor-phase) propylene continues to polymerize, which worsens heat transfer and increases the risk of (caking that blocks the reactor). ========================================= ☛[Haichuan Activity Plan] I decide my own questions – I’ll choose the “best answer”! http://bbs.hcbbs.com/thread-1618021-1-1.html (Source: Haichuan Chemical Industry Forum)
(In the gas phase) the polymerization of propylene continues, and heat transfer deteriorates, making caking and reactor blockage likely
(In the gas phase) the polymerization of propylene continues, and heat transfer deteriorates, making caking and reactor blockage likely
Aggregation, heat transfer under solid-state conditions, caking.
The polymerization reaction of polypropylene continues to deteriorate, making it prone to sticking to the pan
The disadvantage of recycling too late is that after the \"dry pot\" stage, polypropylene continues to polymerize, causing the reaction to deteriorate and increasing the risk of explosion.
The disadvantage of delayed recycling is that after the \"dry cooking\" process, unreacted propylene continues to polymerize, which worsens the situation and increases the risk of clumping due to overheating.
Vapor phase, product quality; can cause serious accidents such as localized explosive agglomeration and melting in the reactor
