What is Column Packing?
Column packing refers to the material used inside a packed column to improve surface contact between gas and liquid phases. This facilitates better heat and mass transfer, essential in processes like distillation, absorption, and chemical reactions.

Notes on the Use of Column Packing
- Due to their low bulk densities, Glass Raschig rings are particularly suitable for packing glass columns.
- Generally, the ratio of Column diameter to packing diameter should not be less than 8:1.
- When using smaller packing size, a small layer of larger packing should be used on packing support, to prevent the smaller packing falling through.
- In vacuum application and applications involving high vapour velocities, packing may be lifted and may damage to other parts. To prevent this, a packing retainer (PTFE perforated plates) should be used above the packed section.
