METHOD FOR DIVIDING MULTICOMPONENT MIXTURE AND DEVICE FOR CARRYING OUT SAID METHOD

摘要

The inventive method for dividing a multicomponent mixture involves the following stages: a first restriction of a gas-vapour mixture during the tangential supply of the formed flow thereof to a peripherial reaction zone, a second restriction of the mixture during the transfer of a rotational flow of the mixture from the peripherial zone to a rotational central reaction zone and the formation of the layer of a liquid product which is enriched with a high-boiling component on the reaction zones boundary, at least a third restriction of the mixture and the formation of the layer of the liquid product which is enriched with a high-boiling component on the surface of at least one permeable membrane (14) arranged in the rotatable central zone. The inventive device comprises a body (1) comprising a peripherial reaction chamber (13), a rotor (2) provided with a central reaction chamber (6), a unit (10) for supplying a divisible medium in the form of a tangential slotted nosepiece (11) which is embodied in such a way that it is enabled to restrict the mixture, and a unit for removing the liquid product enriched with the high-boiling component. The rotor comprises a unit (15) for introducing the divisible mixture into the central reaction chamber (6) embodied in such a way that it is enabled to restrict the mixture, at least one coaxially arranged cylindrical membrane (14) embodied in such a way that it is enabled to restrict the mixture, and a unit (18) for removing the liquid product enriched with the high-boiling component from the central reaction chamber (6) to the peripherial reaction chamber (13).
