Abstract: The invention relates to a method for separating titanium tetrachloride and the hydrolyzed reaction products of titanium tetrachloride from the exhaust gases generated during the chlorination of raw materials containing titanium by treating the exhaust gases with a first aqueous hydrochloric-acid solution of titanium oxychloride, where, in the first separation stage (2), small droplets of hydrochloric-acid titanium oxychloride solution (3) are flowed with the exhaust gas flow, and larger droplets of hydrochloric-acid titanium oxychloride solution are flowed counter current to the exhaust to remove the smaller droplets and ensure that virtually no droplets are carried to a second separation stage. In the second separation stage, a second titanium oxychloride solution is injected into a second reactor (9), the second solution having a lower titanium oxychloride concentration than that injected in the first separation stage. The method results in a lower pressure loss in the scrubber system, while retaining the same separation efficiency.
