  • Recovery process and apparatus for alkali metal-containing spent liquor
    Patent number: 4154643
    Abstract: An alkali metal-containing spent liquor is treated to recover the alkali metal content for reuse without the need for recycling furnace ash and forming solid pellets therefrom. A mixture of aluminum hydrate and alkali metal-containing waste liquor is directed through a heated furnace and dried to form granules of the aluminum hydrate and waste liquor solids, and the organic content of the granules are combusted and reacted to form granular alkali metal aluminate furnace ash. The granular furnace ash is removed from the furnace and treated to recover the alkali metal and to produce aluminum hydrate for reuse in the process.
