Question

Why diameter of vacuum distillation column of larger than diameter of normal distillation column

Answer 1

Distillation of high-boiling and/or air sensitive materials

Distillation is used to separate compounds based on differences in boiling point. Vacuum distillation allows for this purification technique to be used on compounds with high boiling points, or those which are air-sensitive.

Answer 2

Answer:

heya..

Vacuum Distillation Unit. ... The after taking out these lighter hydrocarbon cuts, heavy residue remaining at the bottom of the atmospheric distillation column needs to be refined. These heavy hydrocarbon residues are sent to a Vacuum Distillation Column for further separation of hydrocarbons under reduced pressure.

i hope its help u
