METHOD OF SEPARATION OF MULTI-COMPONENT MIXTURE AND DEVICE FOR REALIZATION OF THIS METHOD Russian patent published in 2003 - IPC

FIELD: mass-exchange processes; petrochemical, chemical, food-processing and other industries. SUBSTANCE: proposed method includes forming of flow of vapor-and-gas mixture to be separated and tangential supply of this flow to peripheral reaction zone; in the course of supply of said mixture, its first throttling is performed. Proposed method includes also forming of revolving flow of vapor-and-gas mixture in peripheral reaction zone and introduction of said flow into revolving central reaction zone; in the course of introduction, second throttling of mixture is performed and liquid product enriched with high-boiling component is formed at boundary of reaction zones of layer. Method includes also placing of at least one partially permeable partition in revolving central zone; said partition is used for performing third throttling of mixture in the course of its radial motion and forming layer of liquid product enriched with high-boiling component. Then, vapor-and-gas mixture is moved radially from periphery to center forming gaseous product enriched with low-boiling component and liquid product enriched with high boiling component at discharge of products thus formed from reaction zones. Device proposed for realization of said method has cylindrical housing and cylindrical rotor with central reaction chamber and peripheral reaction chamber formed between side wall of rotor and side wall of housing. Device is provided with unit for delivery of mixture to be separated made in form of slotted nozzle whose outlet passage is tangential relative to rotor and unit for removal of liquid product enriched with high-boiling component. Rotor is provided with unit for introduction of mixture to be separated into central reaction chamber which may be also used for throttling mixture and unit for removal of liquid product enriched with high-boiling component from central reaction chamber and directing it to peripheral reaction chamber; besides that, rotor shaft has axial passage communicated with central reaction chamber and unit for removal of gaseous product enriched with low- boiling component. EFFECT: enhanced efficiency; increased coefficient of separation. 15 cl, 3 dwg, 1 tbl
