1,024,756. Evaporation systems; distillation of water. LUMMUS CO. Dec. 6, 1963 [Dec. 10, 1962], No. 48289/63. Heading BIB. A solution of dissolved solids is concentrated in evaporation unit 10, e.g. a multiple-effect evaporator, whence the concentrated solution flows through line 12 to submerged combustion unit 13 where the solution is further concentrated by contact with hot combustion gases to give a slurry, the slurry is conveyed through line 19 to filter or centrifuge 18, the mother liquor is returned via line 21 to unit 13, and the hot gases and vapours, withdrawn from unit 13 through line 22, are used as heating medium in evaporation unit 10. The system may be used to produce distilled water and salt from saline water which is introduced into multipleeffect evaporator 10 through line 9. Distilled water is withdrawn from evaporator 10 through line 11. Compressed air in line 16 is mixed with fuel supplied through line 17, and the mixture is conducted to the burner of unit 13. The hot gases and steam leaving the unit 13 flow through line 22 into the heating element of one of the effects of evaporator 10, and the condensed water is withdrawn through line 23. The now cooled gases are passed through line 24 to turbine 25 for driving air-compressor 15. Salt is discharged from the system via line 20.
