How To Reliably Measure The Gas Composition

Titanium dioxide is produced by converting the crude ore into titanium tetrachloride through a carbochlorination reaction utilizing fluidized bed technology. The titanium tetrachloride is then distilled and oxidized back to titanium dioxide. The fuildized bed reactor is typically located outside, exposed to the elements. The gasses inside the reactor are hot, corrosive, and under pressure.

Key to the success of titanium tetrachloride production is optimizing the fludized bed reaction by monitoring and controlling the ratio of certain gasses. If these gas ratios can be measured in real time they can be controlled by varying the raw materials feed rate, bed composition, and other variables.
