Abstract
A liquid-liquid extraction unit includes an extraction/separation tank () into which an aqueous phase in bubble form is admitted from an upper inlet () in one sidewall and an organic phase in bubble form is admitted from a lower inlet () in the one sidewall. The upward moving organic phase is contacted with the downward moving aqueous phase. After contact, the organic phase is discharged through an upper outlet () in an opposite sidewall and the aqueous phase is discharged through a lower outlet () in the opposite sidewall.
