A thermochemical water-splitting process all reactions of which operate at relatively low temperatures and high efficiencies, and in which relatively inexpensive materials and processing methods are made possible. This invention involves the decomposition of a metal halide compound, i.e., one which is capable of being reduced from a higher oxidation state to lower oxidation state, e.g. vanadium chloride III→vanadium dichloride. The process is cyclic and regenerative, and the only net inputs are water and heat; and the only net outputs are hydrogen and oxygen. The process makes it possible to utilize a wide variety of available heat, including solar, sources for the energy input.

The disclosure is directed to a process for isolating solids from a purification purge stream comprising an impurity present as a solid, wherein the purification purge stream is substantially free of chlorides other than titanium tetrachloride and vanadium chloride, the process comprising the steps of: (a) atomizing the purification purge stream comprising titanium tetrachloride as a liquid and an impurity present as a solid; (b) drying solids in the atomized purification purge stream by contacting the atomized stream with a titanium tetrachloride vapor stream such that the combined streams reach a temperature of at least about 140° C. to vaporize the liquid titanium tetrachloride, wherein the titanium tetrachloride vapor is substantially free of chlorides other than those of titanium and vanadium, and substantially free of non-condensable gases comprising CO, CO2, N2, or mixtures thereof; and (c) separating the impurity present as a solid from the vaporized titanium tetrachloride. The separated vanadium solids may be further processed to recover valuable by products.

A titanium tetrachloride vanadium-containing mud treatment technology and equipment, it uses the device and heat energy of the original chlorination system to treat titanium tetrachloride and vanadium-containing mud in the vanadium-containing mud discharged from the crude titanium tetrachloride mineral oil. Techniques for the separation of vanadium solids. Its feature is to use the submerged pump in the titanium tetrachloride vanadium-containing mud storage tank to send the mud to the mechanical rotary sprayer on the top of the first-stage gravity dust collector of the chlorination system, and then spray the mud into the dust collector and The high-temperature mixed gas discharged from the chlorination furnace is counter-currently exchanged for heat, and the titanium tetrachloride droplets in the mud are gasified, and enter the second-stage dust collector with the mixed gas, and most of the vanadium-containing solids settle under the action of gravity. The ash box at the bottom of the dust collector is sent to the flushing system regularly, and a small amount of unseparated vanadium-containing solids enter the second-stage dust collector with the mixed gas for further separation, and the purified titanium tetrachloride gas enters the original production line. The titanium tetrachloride condensation collection system of the system. The process has the advantages of energy saving, low operation cost, high recovery rate of titanium tetrachloride and no pollution of discharged waste residue.
