Several term explanations for distillation columns
Thread Content
I’ve been learning about the operation of distillation towers recently, and I came across a few terms. I would be very grateful if any teachers who understand them could explain them to me! 1. Boiling-point feed 2. Cold-liquid feed 3. Saturated steam feed 4. Gas-liquid mixed feed 5. Superheated steam feed
Regular knowledge can be found on Baidu
Bubble point feeding and boiling point feeding refer to the composition of the feed at that temperature. The bubble point denotes saturation, meaning that at that temperature the sample’s composition is in its most saturated state. The boiling point, on the other hand, refers to the condition where the composition of the material fed at that temperature reaches the dew point, that is, a state of saturation in which all the material is in gaseous form
Which one is more suitable for the separation of materials (multi-component liquefied gas)?
Generally, feeding is done by soaking, but an alternative can also be chosen depending on the actual circumstances
The principles of chemical engineering are explained very clearly!
