Title: Method of reducing the permeability of refractory materials
IPC: C25C3/08
Filed: 1957-12-30
Abstract: 871,114. Crucibles. MONTECATINI SOC. GENERALE PER L'INDUSTRIA MINERARIA E CHIMICA, and DE VARDA, G. Dec. 30, 1957 [Jan. 5, 1957], No. 40349/57. Class 82(1) [Also in Groups V and XXXVI] The permeability of the inner walls of a vessel containing a corrosive liquid metal and composed of porous refractory material e.g. magnesia as used in electrolytic furnaces for the production of aluminium, is reduced by injecting an inert gas e.g. nitrogen, 'carbon monoxide, carbon dioxide, helium or the gas evolved during treatment of the corrosive liquid in the vessel, through the walls of the vessel towards the liquid therein at a pressure sufficient to ensure the formation of gas bubbles on the wall surface contacting the corrosive liquid. The gas pressure, which is preferably of from 1.05 to 3 atmospheres, may be sufficient to cause the gas bubbles to leave the pores at the wall surface and form a gaseous layer between liquid and wall. The pores are preferably pre-treated by impregnation with pitch which is subsequently cokefied, thus regularizing pore size. As shown, fused salt 1 is contained in a heat-insulated vat 2 made of refractory bricks e.g. magnesia of uniform porosity not greater than 15%. Small holes or channels 5 which do not extend to either inside or outside faces of the vat communicate with a tube 8 through which inert gas is passed. Bubbles of gas 13 form at the pores in the wall surface. Vat surfaces 6 and 9 not in contact with corrosive liquid are preferably sealed and insulated e.g. by metal coatings or, where vats are constructed of magnesia for use at temperatures below 950‹C. by potassium metaborate, calcium and potassium sulphates, and potassium metasilicate or disilicate. Evolved gas leaves by a pipe 14. The process may be applied to a multi-cell electrolytic furnace such as that described in Specification 800,092.
Patent GB-861946-A (GB)
Title: Improvements relating to ion-exchange processes and apparatus
IPC: B01J49/90
Filed: 1958-12-17
Abstract: A conventional cylindrical vessel 1 has upper and lower collecting and distributing devices 2 and 3 extending transversely across it enclosing an ion-exchange bed.  A pipe 4 with two-valve-controlled branches 5 and 6 is connected to the space 7 in the top of the vessel 1 above the device 2, and a similar pipe 8 with two valve-controlled branches 9 and 10 is connected to the space 11 below the device 3. An apertured plate 12 spans the vessel transversely.  To start service flow from the position shown in Fig. 1, the liquid under treatment is introduced through the pipes 9 and 8 and the device 3 at a high rate and drives the bed upwards as a <PICT:0861946/III/1> <PICT:0861946/III/2> whole into the position shown in Fig. 2, the space 14 being filled by granules.  The rate is then reduced, while treated liquid flows to service through the pipes 4 and 5 until the bed needs regeneration.  The bed is of greater volume than the space between the device 2 and the plate 12, so some of it does not pass through the plate and this part drops downwards at the decreased rate of liquid flow to leave a space 15 below the plate 12.  Regenerant (or eluant) is introduced through the pipes 6 and 14, and its downward flow causes the bed of granules to move downwards as a whole, so that the space 15 below the plate 12 is completely filled with granules, as shown in Fig. 1.  The effluent liquid leaves through the pipes 8 and 10.  After regeneration has been completed by rinsing away the excess regenerant by a flow of water in a downward direction, upward flow of the liquid to be treated begins again. Such disturbance of the bed as is caused by the passage of granules through the plate 12 can be minimized by putting the plate at only a short distance, say 10 or 12 inches, above the device 3.  The minimum upward velocity through the apertures in the plate 12 necessary to ensure that the bed is continuously pressed against the device 2 varies with the nature of the ion-exchange granules in question.
