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.degree. 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, CO.sub.2, N.sub.2, 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.
