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.
Claims19
Liquid-liquid extractor comprising a block hollowed with a mixing cell and a settling cell in communication, inlet ducts of two liquid phases leading to the mixing cell from opposite lateral faces of the block and outlet ducts of the two liquid phases leading from the settling cell to the opposite lateral faces of the block, wherein openings of the inlet and outlet ducts of one phase on the opposite lateral faces are in alignment in a direction perpendicular to the opposite lateral faces, and openings of the inlet and outlet ducts of the other phase are likewise in alignment in this direction, wherein the outlet ducts are equipped with overflows adjacent to the settling cell, and each provided with an overflow edge of the liquid phases having an irregular height in the form of a broken line delimiting a plurality of reliefs, further comprising settling equipment that can be plugged into the settling cell by translation and comprising a drawdown plate plunging into the settling cell and continuous up to a guard distance with a bottom of the settling cell.
