Operating and mass transfer characteristics are reported for a supported froth apparatus consisting of a dual‐flow sieve plate column with eggcrate packing above the plate. The assembled packing produced a series of vertical tubes and served to support the froth generated at the plate, increasing its height and consequently the contact time. Addition of the packing improved the mass transfer efficiency. Systems studied were ammonia–air–water and carbon dioxide–air–water. Effects of liquid and gas rate as well as packing size and spacing are correlated. A model based on measurable physical parameters was developed to predict efficiency, and a generalized correlation of efficiency was developed.
