PROCESS FOR CONTROLLING THE FLOW OF TITANIUM BEARING MATERIAL INTO THE FLUIDIZED BED REACTOR IN THE MANUFACTURE OF TITANIUM TETRACHLORIDE |
摘要 |
<p>This disclosure relates to a process for controlling chlorination reactions in manufacturing titanium tetrachloride in a fluidized bed reactor, optionally followed by processing to form a titanium product comprising an amount of silica, the process comprising: (a) feeding carbonaceous material, titanium bearing material comprising an amount of silica, and chlorine to the fluidized bed reactor to form a gaseous stream, and condensing the gaseous stream to form titanium tetrachloride, a non-condensed gas stream and a condensable product stream, wherein at least one of the titanium tetrachloride and the non-condensed gas stream comprise silicon tetrachloride; (b) analyzing the non-condensed gas stream, the titanium tetrachloride or both, to determine the analyzed concentration of silicon tetrachloride; (c) identifying a set point concentration of silicon tetrachloride based on the desired amount of silica in the titanium product; (d) calculating the difference between the analyzed concentration of silicon tetrachloride and the set point concentration of silicon tetrachloride; and (e) generating a signal which corresponds to the difference calculated in step (d) which provides a feedback response that controls the flow of the titanium bearing material into the fluidized bed reactor.</p> |
