Abstract
<PICT:0791651/III/1> In the purification by distillation of titanium tetrachloride, such as that produced by chlorination of titanium ores in the presence of carbon, the liquid is vaporized by circulating it between a tank and a calandria having substantially vertical tubes which are externally heated by a heating-medium such as steam, and the arrangement is such that liquid titanium tetrachloride is carried up the interior of the tubes by the lifting-action of the vapour bubbles therein. Overheating is thereby avoided; and since only a small quantity of liquid is present in the tubes at any time, the risks attendant upon tubefailure (hydrolysis of TiCl4 &c.) are diminished. The hot tetrachloride is returned to the tank below the surface of the liquid therein. By adding a purification agent, e.g. a mineral, animal or vegetable oil, soap, hydrogen sulphide or copper powder, to the titanium tetrachloride it is possible to render the vanadium constituent non-volatile; furthermore the distillate contains not more than 0.01 per cent carbon. In the apparatus shown, tank 14 has a capacity of 20 cubic meters, and calandria 16 contains mild steel tubes (10 ft. long and 2 inches diam.) comprising a heating surface of 200 square feet. Down-leg 15 leads from just above the bottom of tank 14 to the lower manifold of the calandria. Tank 14 is also connected to packed-column 18 and condenser 19. A preliminary small quantity of titanium tetrachloride was pumped from storage tank 11 into tank 14, and raised to the boil by circulation through the steam-heated calandria. Tank 14 was then gradually filled to contain 15 cubic meters of titanium tetrachloride through thermostatically-controlled valve 13 so that the liquid was maintained at the boil. The normal working steam-pressure corresponded to 120 p.s.i.g. An addition of 0.5 per cent by weight of an olive oil soap was made, and the boiling was continued under reflux for one hour. The liquid was thereafter distilled, first with reflux to remove the greater part of the silicon tetrachloride, and later without reflux until the volume of the distilland was reduced to 5 cubic meters. The distillate was removed from the system via cooler 22. Tank 14 was then recharged with crude titanium tetrachloride, and the cycle conducted as before except that only 0.2 per cent by weight of soap was added. In this way 20 cycles were conducted before the distilland became so viscous that the rate of heat transfer was reduced to one-half the initial value. This distilled, which amounted to 2 1/2 per cent of the total volume of feed, was discharged via conduit 32 to sludge tank 33 for subsequent separate recovery of titanium tetrachloride.
