Abstract
A method for the integration of a manufacturing facility with a salt dome, which manufacturing facility is one for the production of high purity titanium dioxide using chlorine as a reactant. The metal chlorides produced as a by-product of titanium dioxide production are reacted with sodium hydroxide to produce metal hydroxide precipitates in an aqueous sodium chloride solution, which is then conducted into a reservoir of brine in a salt dome. The metal hydroxide precipitates are allowed to settle and the sodium chloride solution mixes with the brine. A portion of the brine is conducted to the surface where it is decomposed to produce chlorine, hydrogen, and sodium hydroxide. The chlorine and sodium hydroxide are recycled for use in the overall integrated process.
