ABSTRACT:
A liquid extraction process involving countercurrent flow of aqueous and organic liquid phases with gas dispersion in the organic phase is carried out in a pulsed column with for example a knitted bed, and the organic phase is discharged into the bed via a tube which physically supports the bed and is used for (optional) reciprocation of the bed to pulse the phases.
