To purify the insoluble titanium dioxide, it is washed free of soluble impurities in a continuous, countercurrent system of thickeners with water. Two hundred thousand kg/h of 99.9 wt% titanium dioxide pigment is to be produced by washing, followed by filtering and drying. The feed contains 50 wt% TiO2, 20 wt% soluble salts and 30 wt% water. The wash liquid is pure water at a flow rate equal to that of the feed on a mass flow basis .Determine the number of ideal stages using the McCabe-Smith method. kg solute/kg solution kg solution/kg TiO2 0.0 0.30 0.2 0.34 0.4 0.38 0.6 0.42arrow_forwardComplete the following precipitation reactions using balanced chemical equations:arrow_forward
