TiCl4 is formed by reacting titanium dioxide (TiO2) with hydrochloric acid (see reaction below). TiO2 is available as an ore containing 88 % TiO2 and 12 % inerts. The HCl is available as 50 wt% solution (the balance is water). The per pass conversion of TiO2 is 55 % (this means that 55% of the titanium dioxide entering the reactor is converted to products). The HCl is fed into the reactor in 20 % excess. Pure un-reacted TiO2 is recycled...
