Abstract
A method and apparatus for producing TiO.sub.2 by reacting O.sub.2 and TiCl.sub.4 in a reactor tube wherein pressure fluctuations in the flow of fluids through the reactor tube are sensed and output signals are generated proportional to the sensed pressure fluctuations. The flow of at least one of the TiCl.sub.4 or O.sub.2 is then varied through the reactor tube in response to predetermined pressure fluctuations so as to increase the efficiency of the reaction between TiCl.sub.4 and the O.sub.2. The efficiency of the reaction between O.sub.2 and TiCl.sub.4 in the reactor tube is achieved by a control apparatus operably connected to the reactor assembly which is capable of monitoring pressure fluctuations in TCl.sub.4 and O.sub.2 through the reactor assembly so that the flow of at least one of the TiCl.sub.4 or O.sub.2 can be varied in response to predetermined pressure fluctuations. The control apparatus includes a sensor assembly, a signal conditioning unit and a signal processing unit.
