Analysis of Reactors for the Production of Titanium Dioxide Through Computational Fluid Dynamics

Abstract

The purpose of this research was to examine a group of chJoride-proces titanium dioxide (Ti02) reactors, and evaJuate for their merits in eliminating deposition of solid Ti02 product on the reactor waJls. This is important to the industriaJ pigment industry, as a great deaJ of effort is put into reducing or ehmating this deposition to control particle size, and reduce reactor down time for cleaning. ComputationaJ fluid dynamic (CFD) modeling was used to examine kinetic and thermodynamic phenomena within these reactors, while reactant nozzle configurations were altered to evaluate their effect on deposition.
