METHOD FOR SEPARATION OF MIXTURE (THREE MODIFICATIONS) AND METHOD FOR PUMPING OF HEAT-TRANSFER AGENT (FOR USE IN THE THIRD MODIFICATION OF THE METHOD FOR SEPARATION OF MIXTURE) Russian patent published in 2004 - IPC

FIELD: separation of mixture of absorbent and working agent. SUBSTANCE: separation is accomplished by delivery of mixture to the channel through a capillary-porous partition dividing it into a supply region and a separation cavity. For evaporation heat is supplied to the surface section of the capillary-porous partition in the cavity of separation or to the layer of the capillary-porous partition adjoining the cavity of separation, and/or to the layer section inside the capillary-porous partition. Evaporation is effected with formation of a steam or steam-liquid medium that is transferred to the cavity of separation, from which steam and residue are discharge separately. In the cavity of separation steam may be partially condensed. At evaporation in several channels steam from the outlet of one channel is fed to the inlet of the other channel, and/or the residue from the outlet of one channel is fed to the inlet of the other channel, and evaporation is effected in the capillary-porous partition installed at least in one channel. Pumping of the heat-transfer agent from the supply region to the evaporation sections is effected at a steam pressure exceeding the pressure in the supply region. EFFECT: expanded store of hardware components for separation of mixture. 9 cl, 6 dwg
