Patent GB-796967-A (GB)
Title: Recovery of titanium tetrachloride
IPC: C22B34/12
Filed: 1956-01-05
Abstract: In the separation of normally solid metal chlorides from hot titanium tetrachloride vapour by scrubbing the hot vapour with liquid titanium tetrachloride, the solids are removed as a free-flowing slurry in liquid tetrachloride, the slurry containing not more than 40 per cent solids, and the amount of liquid tetrachloride fed is such that no nett condensation of tetrachloride <PICT:0796967/III/1> vapours occurs.  The temperature of the liquid titanium tetrachloride used for washing may be between 0 DEG  and 136 DEG  C., but preferably is between 70 DEG  and 130 DEG  C.  Having selected a temperature, an amount of liquid tetrachloride is selected so that the amount of gaseous titanium tetrachloride leaving the cooling zone is at least equal to the amount introduced in the vapour state, whilst leaving a sufficient residual excess liquid titanium tetrachloride to form the free-flowing suspension of solid chlorides.  The said solid chlorides consist of ferric chloride, aluminium chloride and oxidic chlorides. The cooling zone may be provided with filling.  Part at least of the titanium tetrachloride vapour leaving the cooling zone may be condensed and returned to serve for spraying together with at least part of the titanium tetrachloride contained in the liquid outflow from the heat exchanger after separation of the inpurities therefrom. Such impurities may be separated by distillation and condensation. As shown in Fig. 4, chlorination gases coming from a chlorinator 7 flow through the conduit into a heat exchanger 1 provided with packing, where the vapours are contacted with liquid titanium tetrachloride from conduits 3a and 3b.  The vapours leave through pipe 4 and are condensed in condenser 5, the residual gases passing off through line 8.  The condensed tetrachloride is in part withdrawn as product at B and in part re-cycled in liquid form through line 3a.  The slurry of impure titanium tetrachloride containing the entrained solid chloride impurity passes through conduit 6 into an evaporator 11 provided with a heating element 12.  Oil is supplied to the evaporator through line 13 to assist in the purification of the tetrachloride and the titanium tetrachloride vapour passes through conduit 15 to a condenser 16, the residual gases leaving through line 17.  Part of the liquid tetrachloride from the condenser 16 is returned to the cooling zone 1 via a further cooler 18.  Overflow of liquid titanium tetrachloride from condenser 16 passes back through conduit 20 and can be discharged as product at A.  The slurry of liquid tetrachloride and the solid chloride impurities is withdrawn from the evaporator 11 through a pipe 14 and sent to drum driers in order to recover the titanium tetrachloride entrained therein. Specification 679,537 is referred to.

Title: Fluid-flow control apparatus
Inventor: TYLER STANLEY RALPH
IPC: G05D7/03
Filed: 1964-01-08
Abstract: 1,076,977. Fluid-pressure servomotor systems. DOWTY FUEL SYSTEMS Ltd. Jan.6, 1965 [Jan.8, 1964], No.884/64. Heading G3P. [Also in Division F1] Apparatus for controlling the rate of flow of fluid from a pump 51 to a device which requires a continuous flow of fluid at a rate which depends upon the magnitude of a variable factor, comprises a piston valve 16 controlling the amount of fluid by-passed back to the pump inlet, the piston defining end-chambers 19, 21 which communicate with nozzles 36, 35 respectively, the nozzles co-operating with a lever 32 pivoted at 33 and abutting a bellows 45 which receives an input signal corresponding to the said variable factor. The output from the pump flows through a flow-responsive device 25 comprising an obturating plug 29 carried by a lever 27 pivoted at 28 and carrying a piston 30 working in a dashpot. A torsion bar 31, perpendicular to levers 27, 32, connects these levers at their pivot points. In operation, when a signal is applied to the bellows 45 the lever 32 moves relative to the nozzles and causes the piston valve to move to alter the amount of fluid by-passed. The corresponding difference in flow through device 25 moves lever 27 which resets the lever 32 via torsion bar 31. If the signal is constant, the device 25 will function via torsion bar 25 and lever 32 to maintain a constant flow. In a modification Fig. 1 (not shown), the gear pump is replaced by a centrifugal pump, the connections between the nozzles and the chambers 19, 21 are reversed and the piston valve controls the outlet from the pump by variably throttling the flow passage through the valve. In the further modification of Fig. 3 (not shown), a centrifugal pump 61 has a inlet valve comprising a seat (64) co-operating with a tubular member (66) integral with a piston (67) defining a small-area, highpressure chamber (71) and a large-area, lowpressure chamber (72), the chambers receiving operating fluid from a conduit (73), the chamber (72) also communicating with an exhaust passage (79) via a valve member (78). When a control signal is applied to a piston (82), the member (78) is moved to vary the exhaust connection of chamber (72) and thereby causes the piston (67) to move to adjust the pump inlet valve. The change of fluid flow through device (25) moves lever (27) which applies a restoring force to lever (32) via torsion rod (31).
