FIELD: treatment plants.
SUBSTANCE: invention relates to the method of separating components of liquid load with the help of liquid-to-liquid centrifugal chromatography and the device for carrying this out. Components (A, B), which have different partition coefficients, such that these components lead to movement with different speeds respectively with the help of a light solvent (I) and a heavier solvent (L), continuously inject in some intermediate point of the separating column. After that alternating of cycles is carried out, consisting of two phases: in the first phase the heavier solvent is injected, in the second - the lighter one. In the process of each of these phases separated components (FA, FB) are collected on opposite ends of the separating columns at the injection points of the solvent. Separating device contains at least one liquid-to-liquid centrifugal chromatography column, formed in a cascade on at least one chain of parting cells. To each column is attached a pump for injecting the load (P1), pumps for injecting the first and second solvents (P2 and P3), containers for collecting the first (FA) and second (FB) components, means for alternating the switching of valves (V1 and V2). Switching of valve takes place in such a way that, it moves in an alternating sequence from the first phase with the injection of the first of the solvents (L) and collection of the second separated component (FB) to the second phase with the injection of the second solvent (I) and collection of the first separated component (FA).
EFFECT: proposed method and device makes it possible to reduce costs in the mobile phase, and carry out injection of the load in continuous and intermittent regimes.
