10.12 Choice of Column Type

You’re a young engineer asked to design a distillation column. Do you use trays, random packing, or structured packing?

Kister et al. (1994) considered which column to use in considerable detail. They concluded that in vacuum columns, particularly high vacuum, the lower pressure drop of packing is a major advantage and packed columns will have higher capacities and lower reflux ratios than tray columns. For atmospheric and pressure columns pressure drop is usually unimportant, and one needs to compare optimally designed tray columns to optimal packed columns. An optimally designed tray column balances tray and downcomer areas so that both restrict capacity simultaneously. An optimally designed packed column has good ...
