Process for separating solids from a purification purge stream

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.
