  • Device for separating phases of a diphasic mixture and its application to the determination of the physical and/or chemical parameters of this mixture
    Patent number: 6758964
    Abstract: A device for separating and renewing phases of a diphasic liquid—liquid mixture, in which a first liquid phase and a second liquid phase are circulated in counter current in a liquid—liquid extraction device. The device is in the form of a straight hollow cylinder with one of the bases being either the wall of the device or being in contact with the wall of the device. The device also includes an input orifice for the phase the user wishes to trap, an output orifice that is smaller than the input orifice for the phase that the user wishes to trap, separated, and a third orifice of an intermediate size when compared to the size of the input and output orifices for evacuating a non-desired phase.
