| titleOfInvention | Process for the removal of chlorine from off-gases |
| abstract | The invention relates to a process for the removal of chlorine from off-gases which continuously or sporadically contain small amounts of chlorine, through scrubbing them with a ferrous chloride-containing aqueous solution in a scrubbing system. The solution used is obtained in dissolving a solids mixture which results from the chlorination of a titaniferous and ferriferous feedstock material and essentially contains-ferrous chloride. This solution is used in particular for the scrubbing of off-gases formed in the production of titanium dioxide by the chlorination of titaniferous and ferriferous feedstock material, thus generating titanium tetrachloride and ferrous chloride, and by the reaction of the titanium tetrachloride with oxygen-containing gases. It is preferably the solids mixture separated in this process from the chlorination mixture in a condensation step that is dissolved in the process of the invention, and at least part of the resulting solution is used for the scrubbing of the off-gas. Known devices can be used for scrubbing, e.g. packed columns. |
