| titleOfInvention | Process for producing titanium dioxide slurries from micronizer tails |
| abstract | The present invention provides an improved process for the production of titanium dioxide slurries. The output from the ultramill is passed through a condenser to condense the vapor and form an aqueous slurry of titanium dioxide, which slurry is then used in an apparatus for separating TiO 2 from the vapor, as is currently practiced in the art. Instead of moving the output, in most cases it can be further concentrated as needed, or sold or used without further concentration. The resulting slurry from the condenser is preferably transferred to a stirred storage tank together with the dispersant and the anti-sedimentation compound in order to help prevent the precipitation of titanium dioxide solids from the slurry in further purification steps. To facilitate the condensation of the vapor / pigment mixture sent to the condenser, a portion of the concentrated slurry is pumped from the slurry storage tank to the heat exchanger in a further purification step. The output from the heat exchanger is then fed to the condenser to promote condensation of the steam in the condenser. The temperature and volume (flow) of the cooled condensate delivered to the condenser is set to match the amount of steam and the steam temperature to ensure that substantially all steam and pigment contained are collected from the condenser. |
