Refrigeration tower diameter change
Thread Content
Why do some distillation columns have a variable-diameter structure? For example, the diameter in the upper section is a bit smaller
The higher up the tower, the lower the load, reducing costs
Improve distillation efficiency and reduce reflux flow
It is recommended that you understand the principle of your current tower thoroughly; then this problem will no longer be an issue.
Depending on the proportions of light and heavy components in the feed, a variable-diameter design is employed to reduce equipment investment as well as the amount of reflux or reboiling required
