Abstract
1,113,580. Separation of crystals from solution by flash and multiple-effect evaporation. CHICAGO BRIDGE & IRON CO. 24 Jan., 1967 [25 Jan., 1966], No. 3613/67. Heading BIB. An aqueous solution of two crystallizable compounds, e.g. caustic soda and sodium chloride, is concentrated so that one of the compounds crystallizes out, by conducting the solution through line 10, regenerative heaters 12, 14, 16, 18, and preheater 22 into the vertical tubes of falling-film evaporator 30, the hot liquor is then conducted through line 38 to flash zones 40, 42, 44, where flash vaporization and cooling occurs accompanied by formation of sodium chloride crystal nuclei. The nucleated liquor is passed through line 52 into the second effect 54 of a multiple-effect evaporator system 58, 54, 56, a slurry of salt crystals in liquor is withdrawn from effect 54 through line 66, and passed to tank 70, where the crystals are separated. The liquor is conducted through line 76 into the third-effect evaporator 56 where further sodium chloride crystallizes, the slurry being collected in tank 84, where the crystals are separated. The motherliquor is conducted through line 88 to firsteffect evaporator 58 which is heated by the vapours evolved from the solution in filmevaporator 30. The concentrated solution. withdrawn from effect 58, is passed through line 102 into flash evaporator 103 where the residual sodium chloride crystallizes out. These crystals are separated in tank 118, and a solution of caustic soda is withdrawn through line 124. The condensate withdrawn from the heat-exchanger 91 of effect 58 through line 99, is passed through heaters 18 . . . 12. The condensate withdrawn from the heat-exchanver 63 of effect 54 is passed via line 106 into the heat-exchanger 133 of effect 56. Other solutions which may be treated are caustic soda containing sodium sulphate and sodium carbonate. and brines containing sodium chloride, calcium chloride, and magnesium salts.
