| Popis: | It is hoped, in conclusion, that the practical experience with the tube digester proves: 1. There is not waiting time required for extraction, and it is sufficient to heat pulp to the temperature proper to the bauxite. 2. The sojourn time can be reduced to 150 sec to this end. 3. The tube digester, in many respects, has a better duration function than the autoclave series with corresponding consequences for the transmutation. 4. The desilication is complete. 5. The quartz does not appear to be more attacked than in autoclaves. 6. The settling behavior of the red mud is often much better than low temperature red mud. |
