Method for treating titanium dioxide reactor discharge containing products of nitrogen fixation |
| abstract |
Pigmentary titanium dioxide is produced by vapor phase oxidation of titanium tetrachloride with oxygen at elevated temperatures in a reactor. Gaseous and solid products produced by the reaction are separated and chlorine recovered from the gaseous portion in a chlorine recovery zone. Obstruction of the chlorine recovery zone by products resulting from nitrogen fixation is prevented by scrubbing reactor discharge gas with liquid chlorine, liquid titanium tetrachloride or liquid chlorinated solvents. Removal of the obstruction is accomplished by heating the chlorine recovery zone. |
