  • Patent number: 12017153
    Abstract: These liquid-liquid extractors are adapted to very low fluid flow rates passing through them. In order to reduce the influence of capillarity and air phenomena that may make the flow irregular, the outlet ducts comprise, downstream of the settling cell where the heavy and light phases separate, overflows of the phases the edge of which is irregular in height, for example serrated. The circulation channels of the phases are advantageously open to also reduce the risks of blocking by air bubbles.
