LIQUID-LIQUID EXTRACTOR AND BATTERY CONTAINING SUCH EXTRACTORS Russian patent published in 2025 - IPC B01D11/00 

FIELD: performing operations.

SUBSTANCE: group of inventions relates to a liquid-liquid extractor and a battery for liquid-liquid extraction, comprising at least one liquid-liquid extractor. Liquid-liquid extractors are adapted to very low flow rates of liquid passing through them. Outlet passages contain downstream of the settling chamber, where heavy and light phases are separated, phase overflows, the edge of which has an irregular in height shape, for example, toothed. Circulation channels of the phases are preferably open in order to also reduce the risk of blocking the liquid with air bubbles.

EFFECT: group of inventions reduces the effect of capillarity and air effects, which can make the liquid flow irregular.
