PVC distillation column

This post was last edited by Oath-taking on 2011-11-5 16:59. In PVC production, there are condensers and total condensers at the top of the stripping tower – what is the function of each? What are the advantages of this design?
We only have a top condenser, which is mainly used to condense the water vapor in the gas at the top of the tower. Do you mean the full condenser as referring to the first and second condensers?
Reply to 2# kansam: No, there is a condenser on the stripper, and an overall condenser is placed next to it; I’m not sure if that serves to provide further cooling Struggling with it
The top of the stripping tower is equipped only with a regular cooler, without a total condenser
Reply to 4# clq20040107: Well, with Japanese technology, the condenser is located on the stripping tower, while the full condenser is not on the tower; the gas passes through in a certain sequence
Reply to 5# Wandering Steps: You should have said it was Japanese craftsmanship earlier! His total condenser serves the same purpose as the total condenser in front of the distillation tower
Hey, does anyone have a complete set of PID flowcharts for the PVC industry? Could you send one to me? My email address is 13709006334@163.com. Thanks!
What’s at the top of the tower shouldn’t be a condenser; it should be a heat exchanger. The gas-phase pipelines emerge from the top of the tower, and it is after that connection that a condenser is installed. I’ve seen two Japanese-style towers that are set up this way.
In small Japanese plants, the tops of the towers are used to heat deionized water through preheating, either for flushing the tray plates or for supplying hot water to the polymerization reactors.
The condenser is cooled using general-purpose pure water, which serves to achieve initial condensation; this pure water is reused afterward. The full condenser, on the other hand, is cooled with cooling water, which is recycled.
The condenser can only condense a portion of the water contained in the mixture discharged from the stripping tower. The full-condenser, on the other hand, can further condense the water present in the remaining mixture discharged from the condenser; it can also condense the water in the mixture discharged directly from the slurry stripping tower when the condenser is not functioning properly, offering greater capacity
