ABSTRACT:
A process for liquid-liquid counterflow extraction based on the mixer-separator principle is disclosed. A dispersion of two liquid phases is fed to a separator and the clear phases are withdrawn therefrom. The dispersions to be separated are fed to the separator in two partial steams equal in rate of flow and flow through the separator in mutually opposite directions along respective paths each having a length equal to one-half of the diameter of the separator. Apparatus for carrying out the process includes inlets for the dispersion to be separated positioned at two opposite points of the periphery of the separator and outlets for the separated clear phases lying on the intervening diametral chord. The outlets and inlets can be reversed.
