    摘要： Anatase titanium dioxide pigment calcined to a crush strength and density meeting the requirements for an acceptable scour medium is effectively utilized as a scour medium in the chloride process for producing rutile titanium dioxide. The calcining process converts a portion of the anatase pigment to rutile. This calcined anatase can, consequently, be utilized as a scour medium in the chloride process for producing rutile titanium dioxide. The calcined anatase is not a contaminant to the process for producing rutile titanium dioxide. Thus, relatively inexpensive anatase can be converted into a rutile scour medium that can be processed into pigment.

    摘要： A novel, circumferential air knife is provided which injects a gas stream along the inside walls of the air knife. The air knife can be advantageously placed at or near the entrance to a suspension vessel to reduce buildup of solid materials transported to the suspension vessel. The gas stream is injected at a rate sufficient to reduce the buildup of solid materials on the walls of the air knife (and thus at the entrance to the suspension vessel). The air circumferential air knife is particularly useful in a TiC14 production process for reducing buildup of hygroscopic cyclone dust at the entrance to a suspension vessel.

    摘要： Methods and apparatus for detecting wear in a liner (1400). In one embodiment of the present invention, an electrically conductive wire (1402) is placed on or near the outside surface (1404) of the liner and the electrical resistance in the electrically conductive wire (1402) is measured to determine whether the wire has worn through. In another embodiment of the present invention, the temperature measured by a temperature measuring device, such as a thermocouple, is monitored over time to estimate wear in the liner (1400).
