Two hundred kilograms per hour of an aqueous solution containing 20.0 mole % sodium acetate (NaC2H3O2) enters an evaporative crystallizer at 60°C. When the solution is exposed to the low pressure in the evaporator, 16.9% of the water evaporates, concentrating the remaining solution and causing crystals of sodium acetate trihydrate (NaC2H3O2· 3H2O) to form. The product is an equilibrium mixture of crystals and a saturated aqueous solution containing 15.4 mole% NaC2H3O2. The effluents (crystals, solution, and water vapour) are all at 50°C.4.2.1 Calculate the feed rate to the crystallizer in kmol/h. (4)
