Abstract: In the process for producing titanium dioxide by (a) reacting titanium tetrachloride and oxygen in the vapor phase in a reactor to produce titanium dioxide, and (b) subsequently cooling the titanium dioxide by passing it through a flue consisting of a conventional flue, a finned flue, or combinations thereof, wherein the outlet for the reactor in step (a) has a smaller interior diameter than the inlet for the flue in step (b),the improvement comprising passing the titanium dioxide through a truncated cone-shaped finned flue conduit, the smaller diameter end of the truncated cone-shaped finned flue conduit receiving titanium dioxide produced by the reactor and the larger diameter end of the truncated cone-shaped finned flue conduit discharging titanium dioxide that is received by the flue.
