| titleOfInvention | Process and furnace for the preparation of TiO2 pigment according to the sulfate process |
| abstract | A process for the preparation of titanium dioxide by dissolving titanium raw materials with sulfuric acid, preparing a metal sulphate-containing titanyl sulphate solution, hydrolysing the titanyl sulphate, separating the titanium dioxide hydrate from metal sulphate-containing sulfuric acid by filtration, optionally bleaching the titanium dioxide anhydride solution and doping chemicals and titanium dioxide nuclei, characterized in that the sulphate-containing titanium dioxide hydrate is dried in a dryer at temperatures from 90 to 400 ° C, preferably 90 to 200 ° C, particularly preferably 90 to 150 ° C, and that the titanium dioxide hydrate dust is separated from the dryer exhaust gas by filtration. the dried titanium dioxide hydrate is calcined in a rotary kiln directly heated with flue gases at temperatures in the range from 800 to 1100 ° C (solids temperature) and the exhaust gas is dust cleaned and desulfurized. Calcination furnace for the production of titanium dioxide from dried sulphate-containing titanium dioxide hydrate in the form of a rotary kiln with a length-diameter ratio in the range 5 to 10. |
