A device for separating and renewing phases of a diphasic liquid&mdash;liquid mixture, in which a first liquid phase and a second liquid phase are circulated in counter current in a liquid&mdash;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.

Device for separating phases of a diphasic mixture and its application to the determination of the physical and/or chemical parameters of this mixture

A device measures the propagation time for an acoustic wave in a continuous phase of a two-phase mix ( ) comprising the continuous phase and a dispersed phase forming droplets ( ) in the continuous phase. The device comprises an electro-acoustic transducer ( ) capable of emitting acoustic waves ( ) and outputting a reception signal of reflected acoustic waves, a signal pulse generator capable of determining a propagation time starting from signals output by the transducer, and an acoustic lens for focusing acoustic waves and the frequency of the acoustic waves being adjusted to cause reflection of the waves on the droplets of the dispersed phase, essentially located within a focusing area.
