Titanium tetrachloride can be produced by reacting titanium dioxide with hydrochloric acid. An ore containing 72% TiO₂ and 28% inerts and a solution of 55% HCI are available in the production of titanium tetrachoride. The single-pass conversion of titanium dioxide is 62%. The hydrochloric acid is fed into the reactor in 18% excess. Pure unreacted titanium dioxide is recycled back to mix with the fresh feed. For a titanium tetrachloride production rate of 1250 kg/h, determine: a) the mass rates of ore, HCI solution, recycle b) the composition of the final product c) the mass of titanium dioxide entering the reactor
