  • Metal chloride generator and improved process for the production of metal chlorides used in the manufacture of titanium dioxide by the chloride process
    Patent number: 5683669
    Abstract: In the preparation of metal chlorides from their elements to be used as additives in processes of making titanium dioxide by the chloride process, a titanium tetrachloride stream is directed to sweep over the lined inner wall of a metal chloride generator to act as a protective film, which considerably increases the life of the generator. Furthermore, the titanium tetrachloride is further heated, which is highly desirable in the chloride process. When the titanium tetrachloride is optionally conducted in advance through ducts in the lining of the inner walls of the metal chloride generator, its temperature can be further raised.
