[0002] In the titanium tetrachloride production process, vanadium trichloride in crude titanium tetrachloride cannot be separated by physical methods, and it is necessary to separate vanadium trichloride in crude titanium tetrachloride by chemical vanadium removal methods. At present, many domestic titanium tetrachloride production companies use organic vanadium removal processes. There are many types of organic matter, including mineral oil, fatty acids, industrial white oil and many other varieties. The vanadium removal agent used well has the characteristics of high viscosity and poor fluidity. When used, it needs to be heated to increase its temperature to increase its fluidity. The prerequisite for the stable production of titanium tetrachloride organic vanadium removal process is the continuous and stable addition of vanadium removal agent, and the hourly addition amount is relatively small, within the kilogram range.
