distillation
Thread Content
I would like to ask fellow sailors: why is it necessary to remove low-boiling substances first, and then high-boiling substances, during the distillation process? Thank you.
This question is about what “pressure” means; I’m not quite sure
Low-boiling substances come out at the top of the tower, while high-boiling substances come out at the bottom!
Why is the distillation process for VCM done in this way?
Could you provide more details on the distillation of VCM?
Is this issue popular these days? Since distillation involves separation through heating, it’s inevitable that the light components will vaporize and separate first during the heating process~~·
I hope to have a complete **!
Distillation is a process of heating to cause vaporization; traditional distillation towers can operate in a single stage, with the light components coming out from the top, the monomer from the middle, and the high-boiling substances being discharged from the bottom. This type of process is also used in distillations with low flow rates today. During distillation heating, the light components evaporate first, followed by the monomers, and finally the high-boiling heavy components. If you use a high heating temperature and low pressure, all components will evaporate; by recovering the heavier components first, you avoid wasting resources on the lighter ones.
For those who work with dry polyvinyl chloride, this question is a bit trivial. The forum has a book titled “Polyvinyl Chloride Technology”; go ahead and download it – it explains things very clearly.
