What’s going on with so much water in the recovery pipeline?
Thread Content
Why is there so much water around the recovery pipeline of the farthest polymerization reactor in the monomer recovery main for the polymerization reactors, and why does water keep dripping from it from time to time? Is it an internal leak in the recovery valve?
It’s not internal leakage of the valve; rather, it’s a change in pressure inside the pipeline, with the vaporization of the liquid absorbing heat and causing the water vapor in the air to condense. When I was a child, I would eat ice pops in enamel cups, and cold water would \"leak\" out from outside the cups; I was completely puzzled by this.
The recycled monomer should be in gaseous form originally; how can vaporization occur?
Gas depressurization also absorbs heat, and the presence of liquid monomer cannot be ruled out when the pressure is high during monomer recovery.
Agree with the opinion above! ! In PVC systems, there are many areas where pipes develop dew, and the reasons for this vary! ! It needs to be monitored and summarized regularly! !
If there is persistent dripping around the shut-off valve on the recovery pipeline during operation, it is indeed a leak inside the valve. This has happened to us before: the monomer leaks from the high-pressure polymerization reactor into pipes with lower pressure, where it vaporizes and absorbs heat; ice forms on the outer walls of these pipes, causing water to drip
