Abstract
A process for the separation of volatile chlorine compounds from exhaust gases resulting from the chlorination of titanium-containing raw material by the treatment of the exhaust gases with an aqueous media in several stages and the absorption of the volatile chlorine compounds in the aqueous media. In the first stage, the exhaust gases are contacted with an aqueous solution of titanium oxide chloride and, in the subsequent second stage, the exhaust gases are contacted with water to obtain hydrochloric acid of useful concentration.
