When we use packed bed column and why ?
https://pharmaguides.in/difference-between-packed-column-and-tray-column/
In distillation, packed bed column is a type of distillation column filled with a static bed of randomly packed filling material, such as ceramic or metal pellets, used to increase the surface area for mass transfer. Tray columns have a series of trays stacked vertically, with each tray containing a specific amount of liquid that is allowed to drain and/or redistribute before being sent to the next tray.
Advantages of packed bed columns include:
- Higher efficiency for some separation processes
- Ability to handle viscous and fouling liquids
- Reduced pressure drop
Advantages of tray columns include:
- Better control over the liquid distribution
- Easier to access and maintain individual trays
- Better ability to handle liquid mixtures with large differences in boiling points.
The choice between a packed bed column and a tray column depends on the specific requirements of the distillation process, including feed composition, desired product specifications, operating conditions, and equipment cost.
It is common practice to build a tray column first, then debotleneck with packing at a later date when an expansion is needed
