What type of packing is suitable for small distillation columns with an inner diameter of 10–30 cm (the distillation column is made of stainless steel)? What is the equivalent plate height of this packing?
A distillation column with a height of 10–30 cm is considered to be at the pilot plant scale. High-efficiency structured packing (mesh packing) is generally used; the specific type of packing depends on the mixture to be separated. For systems with a small boiling point difference, mesh corrugated packing requiring a large number of theoretical plates is needed. Generally, the height of such small units is limited; using Wester ring or triangular spiral rings can effectively reduce the tower height. PS: The heights of Wester rings and triangular rings are relatively high. It is recommended to consult multiple filler suppliers to find the actual manufacturers.

If you have a high number of theoretical plates, it is still recommended to use highly efficient structured packing； If the number of theoretical plates is low, use a laboratory random bed (although a random bed packing has a higher number of theoretical plates).
