Abstract

PURPOSE: To easily remove the title soda component as a constant concn. by placing a container for packing provided with a water permeable bottom and packed with alumina granules in a container for washing, and supplying washing water to the containers, from the upper part, held in a autoclave under hydrothermal conditions.
CONSTITUTION: Granular alumina 15 to be treated is charged into container 2 for packing. Autoclave 4 is hermetically sealed, and steam is supplied from steam supply valve 7 to keep the inside of autoclave 4 under hydrothermal conditions. At this time, exhaust valve 18 is closed. Washing water in tank 12 is then spouted in container 2 through pump 11 and washing water supply nozzle 10. The water is gradually filled in container 2 and container 3 for washing, and it overflows from the upper part of container 3 and is drained from the bottom of autoclave 4 through drain valve 8. After treatment for necessary time, discharge valve 18 is opened to discharge hot water left in containers 2,3 from discharge pipe 16 by means of the press. Inside autoclave 4.
