Abstract
In the production of oxides of metals or silicon by the vapour-phase oxidation of the corresponding chlorides, in the absence of gases which would burn to form water, the hot products of the oxidation are quenched <PICT:0849140/III/1> with water thereby cooling them so rapidly that substantially no hydrochloric acid is formed by reaction between the chlorine and the water. Cooling is normally effected to a temperature below 200 DEG C. and preferably below 100 DEG C. The oxides may be recovered as an aqueous slurry by passing the cooled gaseous suspension to a scrubbing tower where it is washed with a further quantity of water. Both quenching and scrubbing operations may be effected by a recycled aqueous slurry of the oxide. As shown in the Figure, titanium tetrachloride is reacted with oxygen to yield titanium oxide and chlorine together with excess oxygen, atmospheric gases and, if an auxiliary fuel is used, carbon dioxide; the oxide-bearing stream, at a temperature of 600-1200 DEG C., is passed into a spray cooling tower 1, supplied with a slurry of titanium dioxide in water at 85 DEG C. by pump P1. A small proportion of the oxide product is slurried in water and flows to a recirculation tank 5, whilst the cool gaseous suspension is passed to a scrubbing tower 2, also fed with oxide slurry from tank 5. The whole of the titanium oxide product is removed in tower 2 as an aqueous slurry and passed to tank 5, whilst the cool gases, now at about 85 DEG C. and saturated with water vapour are passed to a gas-cooling tower 3 where they travel counter current to cold water thereby reducing their temperatures at 25 DEG C. The so-cooled gases are exhausted and treated for the recovery of chlorine. The aqueous pigment slurry obtained in tank 5 is passed to a thickener 7 and from thence to recovery processes. The recirculated slurry is normally of a concentration up to 250 gms/litre of titanium dioxide.
