Abstract

<PICT:0561050/IV/1> <PICT:0561050/IV/2> <PICT:0561050/IV/3> In the dehydration and deaeration of aqueous viscous liquids, e.g. viscose, water soluble resins, by flowing the liquid in film form down the wall of a container under high vacuum, the vacuum is controlled so as to maintain constant the rate of removal of water per unit volume of liquid. In dehydrating viscose the container is maintained under a vacuum of 29.2 inches of mercury and the viscose is pumped continuously through the tank so that the temperature of the body of the viscose in the lower part of the tank is regulated to be about 3 DEG C. below its entering temperature (21 DEG C.). The apparatus comprises a deaeration tank 11 maintained under the required vacuum by a pump 17 having a throttling valve 15. Viscose is supplied through a conduit 23 to a manifold 19 from which it flows over a distributer 27 down the wall of the tank. A re-distributer 35 is preferably provided and the dehydrated liquid is removed by a pump 41 connected to a glass gauge 45 through a line 47 which permits re-circulation of part of the liquid. A thermometer bulb 49 connected to a gauge 51 gives the temperature of the liquid in the manifold. Modified distributing devices are shown in Figs. 3 and 4 the first comprising an annular member 60 having a lip 61 with serrated top edge 63 and hood 67. In Fig. 4 the annular distributor is formed by sections 61 and 71 of different diameter, the lower part of section 71 being bent in to meet section 61. The temperatures of the incoming and outgoing liquid may be used through a controller to control automatically the pressure in the container.
