ABSTRACT

In Chapters 2 through 6, the fundamental physical principles that underpin foam fractionation were described. Foam fractionation works because the target species adsorbs to gas-liquid interfaces, and foam supports a lot of gas-liquid interface but only small amounts of liquid so that the concentration of the target species is enriched. The processes of adsorption to gasliquid interfaces and the hydrodynamics of pneumatic foam and bubbly liquids have been described to the extent that can be utilized by the designer of foam fractionators. The understanding of the fundamental physics will now be used in order to draw mass balances around foam fractionation columns in various configurations to enable insight into the potential process performance of the unit operation.
