Abstract

1290001 Evaporators; concentration of solutions IONICS Inc 1 Dec 1969 [24 Dec 1968] 58575/69 Headings BIB and B1X A volatile component is removed from a liquid mixture by diffusion of vapour therefrom through selective membranes 10 in an apparatus comprising a pack of feed compartments 8, heating compartments 7 and vapour compartments 9 formed by frame members and heat transfer sheets 11, the arrangement being such that two liquid flow compartments are disposed on either side of each vapour compartment, and conduits formed by aligned holes in the membranes, sheets and the gaskets of the frame members supply the feed stream 60, the heating medium (steam or hot water) 62 to their respective compartments while a third conduit 61 serves for applying partial vacuum to the vapour compartments by pumps 26. The liquid enters and leaves the compartments 8 via channels 50..56. The liquid leaves each compartment 8 in a direction away from the immediately adjacent selective membrane 10. In the apparatus shown, feed liquid and heating medium are pumped through tubes 20 and 21 respectively into vacuum spacers 14. These streams then flow in parallel through their respective compartments 8 and 7. The concentrated liquid is withdrawn from the apparatus through tubes 23; and heating medium is withdrawn through tubes 24. In a modified apparatus (Fig. 1, not shown), the feed liquid flows in series through the compartments 8. It is stated that, instead of applying partial vacuum to compartments 9, sweep gas may be passed through them. The apparatus may be used for the concentration of aqueous extracts of coffee, and fruit and vegetable juices. For such aqueous liquors, the membrane-material should be strongly hydrophilic to allow permeation of water and impede the evaporation of organic constituents. The membrane may be made of an organic polymer or a cellulose ester.
