  • Process for controlling the temperature of a fluidized bed reactor in the manufacture of titanium tetrachloride
    Patent number: 5670121
    Abstract: This invention relates to a process for controlling the temperature of a fluidized bed reactor in the manufacture of titanium tetrachloride, wherein an exhaust gas stream comprising carbonyl sulfide, sulfur dioxide, carbon monoxide, carbon dioxide, and chlorine is formed. In the process, the exhaust gas stream is first analyzed to determine the analyzed concentration of carbonyl sulfide (or concentration ratio of carbonyl sulfide to sulfur dioxide), the desired concentration of carbonyl sulfide (or concentration ratio of carbonyl sulfide to sulfur dioxide) in the exhaust gas stream is determined, and the difference between the analyzed concentration of carbonyl sulfide (or concentration ratio of carbonyl sulfide to sulfur dioxide) and the desired concentration of carbonyl sulfide (or concentration ratio of carbonyl sulfide to sulfur dioxide) in the exhaust gas stream is then calculated.
