A METHOD OF RECOVERING SOLID IRON CHLORIDE FROM A MIXTURE OF IRON CHLORIDE AND TITANIUM TETRACHLORIDE VAPORS COMPRISING, PASSING SAID MIXTURE OF VAPORS DOWNWARDLY THROUGH A ZONE AND OVER A COOLING SURFACE SURROUNDING A SECOND ZONE AND EXTENDING ACROSS SAID FIRSTNAMED ZONE IN THE PATH OF FLOW OF SAID VAPORS, PASSING A COOLING FLUID THROUGH SAID SECOND-NAMED ZONE TO MAINTAIN THE TEMPERATURE OF SAID COOLING SURFACE AT SUCH A POINT THAT THE VAPORS ARE COOLED TO A POINT BELOW THE CONDENSATION TEMPERATURE OF IRON CHLORIDE VAPOR, BUT ABOVE THAT OF THE DEW POINT OF TITANIUM TETRACHLORIDE THEREBY DEPOSITING SOLID IRON CHLORIDE ON SAID COOLING SURFACE TO COVER SAID SURFACE, INTRODUCING A PLURALITY OF NON-VOLATILE, INERT SOLID BODIES HEATED TO A TEMPERATURE ABOVE THE DEW POINT OF TITANIUM TETRACHLORIDE INTO SAID FIRST-NAMED ZONE AT A POINT THEREIN ABOVE SAID COOLING SURFACE, DROPPING SAID HEATED SOLID BODIES UPON SAID COOLING SURFACE TO DISLODGE SAID DEPOSITED SOLID IRON CHLORIDE AND RE-EXPOSE SAID SURFACE, REMOVING THE TITANIUM TETRACHLORIDE VAPORS FROM SAID FIRST-NAMED ZONE AND SEPARATELY REMOVING SAID DISLODGE SOLID IRON CHLORIDE AND SAID HEATED SOLID BODIES AS A MIXTURE FROM SAID FIRST-NAMED ZONE AT A POINT BELOW SAID COOLING SURFACE, AND SEPARATING SAID DISLODGED SOLID IRON CHLORIDE FROM SAID HEATED SOLID BODIES, AND RECOVERING SAID SOLID IRON CHLORIDE.
