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.

Manufacture of titanium dioxide with recycle of waste metal chloride stream

Mixtures comprised of the compounds trans-1,2-dichloroethylene and/or cis-1,2-dichloroethylene and perchloroethylene are disclosed; as is a method for cleaning a solid substrate which comprises treating the substrate with said mixtures. A method for precision cleaning is disclosed, comprising the steps of showering the contaminated surfaces with said mixtures and then rinsing said surfaces with said mixtures that have been cleaned by distillation in-system. A method for dissolving and reconstituting polymers, waxes and oils by use of said mixtures or by use of mixtures consisting essentially of trans-1,2-dichloroethylene or cis-1,2-dichloroethylene is also disclosed; as is a method for delivering polymers, waxes, oils paints, pesticides, insecticides and fungicides to a surface by use of said mixtures or by use of mixtures consisting essentially of trans-1,2-dichloroethylene or cis-1,2-dichloroethylene.

Method of cleaning/coating a substrate

Trans-dichloroethylene is used in a pure or in a blended state as a cleaning agent for all acetate-based photographic films. In manual cleaning procedures of still-photography and motion-picture films, a soft, lint-free material is moistened with trans-dichloroethylene, or a blend containing trans-dichloroethylene, and then used to buff the film. The most favorable blend discovered contains 50% trans-dichloroethylene, 50% perchloroethylene. In mechanized cleaning procedures of motion-picture films, it is anticipated that trans-dichloroethylene, or a blend containing trans-dichloroethylene, can be used as the cleaning agent with little or no modification to the existing machines. Trans-dichloroethylene can serve as an effective, non-ozone depleting replacement for 1,1,1-trichloroethane in all film-cleaning applications.
