Abstract

Abstract

Aiming at separating the organic impurities in titanium tetrachloride after vanadium removal by organics refining, Aspen P1us software was used to simulate the rectification process of TiCl₄, and the design parameters of the rectification column were optimized by sensitivity analysis. The optimal design parameters of the rectification column were determined at the reflux ratio of 100, the number of column plate of 68, the feed position on the 24th plate, the top temperature of 64.38 ℃, the bottom temperature of 155.06 ℃, and the distillate rate of 223 kg/h. At the optimum conditions, the purity of titanium tetrachloride after rectification is up to 99.9967%, with the yield ratio more than 99.0%. Organic impurities and SiCl₄ mainly flow into the distillate. The yield of CCl₃COCl in the distillate is more than 99.0%, which meets the separation requirement.
