What are the standards for the reactor diameter, the number of tubes, and the tube diameter of the tubular fixed-bed reactors used in vinyl chloride production? Could someone please explain this in detail? Or where can I find such information? Thank you. This post was last edited by limingshuguang on 2009-4-11 at 16:44.]
You can consult books such as \"Polyvinyl Chloride Technology\", \"Production and Operation of Polyvinyl Chloride\", and \"Polyvinyl Chloride Production Techniques\"
Currently, there are roughly two types in use in this industry: one with a diameter of 2800, where the tubes have a diameter of DN57; and the other with a diameter of 3000, using smaller tubes with a DN45 diameter. The second type is more energy-efficient than the first.
Our old system still uses 2400
We are currently using ones with a diameter of 3200, and the number of tubes is 45
Our factory has models of 2400, 2800, 3000, and 3200
However, the vast majority of manufacturers in China are still using DN2400 converters. In fact, as PVC plants become larger, the future development direction should be fluidized bed reactors
What was said upstairs is correct, but the key issue with fluidized bed technology lies in the mechanical strength of the catalyst; the current catalysts do not have sufficient strength and tend to disintegrate easily.
I agree with what was said above; once the mechanical strength of the catalyst improves, it will be natural to switch the reactor to a fluidized bed format.
One type has a diameter of 2400 or 2800, with tubes of DN57; the other type has a diameter of 3000, with tubes of DN45
We have manufactured 24 units with a diameter of 3200 for a certain factory, featuring tubes with a diameter of 45
We are currently using ones with a diameter of 3200, and there are 2490 tubes
There is no standard **or industry-wide uniformity; it is generally determined through negotiation between the owner and the design firm (which will provide recommendations). Different design firms may come up with different designs – for example, for pipes of the same DN50 size, the wall thickness and number of pipes can vary.)
