  • Feeding device and process and feeding system which utilize the feeding device
    Patent number: 7468176
    Abstract: Feeding device for feeding burned lime to a reaction vessel for causticizing soda liquor to caustic soda. The feeding device, in its upper part, has an inlet for receiving slurry of the burned lime and the soda liquor for formation of said slurry inside said feeding device. The system further comprises a tall and slender feed vessel having a lower part having an outlet defined therein for the slurry. The outlet, via a pump, is operatively connected to the reaction vessel. The process and the feeding system utilize the feeding device, in which process the slurry is created of the burned lime and a first part of the soda liquor, a second part being preheated before addition to the slurry, whereafter slaking and causticizing reactions are completed under elevated temperature and pressure.
