Abstract
Baffle tray columns can be designed and operated so to function as highly efficient scrubbers for the cleaning of flue gases subject to wide variations in flow. The columns are designed and operated such that areas within the scrubbing area operate with a liquid phase continuous froth as the contacting medium. The columns can also contain an integral non-clogging separator for entrainment control.
