Title: Improvements in or relating to aqueous caustic soda production
IPC: C01D1/20
Filed: 1962-08-23
Abstract: Sodium hydroxide is produced by filtering a slurry formed by reaction between lime and aqueous sodium bearing liquor wherein the depth of slurry is maintained so as to submerge at least 40% of the filter, applying a vacuum beneath the filter surface during a sufficient portion of time of submergence to produce a calcium carbonate cake between 1/4 and 3/4 inch in depth, washing the cake on emergence with liquid adapted to provide an air-blocking film on the surface of the cake, the liquid being applied at a rate not exceeding 0.25 gallons per pound of dry weight calcium carbonate solids, and re-applying the vacuum to remove residual caustic soda from the cake by displacement with the wash liquid.  The filter is preferably a rotary drum filter and the slurry is agitated to maintain the calcium carbonate in suspension. The sodium bearing liquor is derived from the smelt dissolver of an alkaline pulp digestion apparatus and the dilution of the caustic soda filtrate is controlled by adding a diluent at one or more points between the smelt dissolver and the filter, the final strength being 7.5 pounds total titratable alkali per cubic foot of liquor. The solids concentrate in the filter is maintained in the range 7-15% by weight.  The wash liquor is applied to the cake for 0.18 to 0.3 minutes and is at a temperature of 150 DEG  to 210 DEG  F.
