An evaporation-crystallization process is used to obtain solid potassium sulfate from an aqueous solution of this salt. The fresh feed to the process (Stream 1) contains 19.6% wt K2SO4. The wet filter cake (Stream 5) consists of solid K2SO4 crystals and a 40% wt K2SO4 solution, in a ratio of 10kg crystals/ kg solution. The filtrate (Stream 6), also a 40.0%wtK2SO4 solution, is recycled to join the fresh feed. 43% of the water in Stream 2 is evaporated and leaves the evaporator at a rate of 175kg/s through Stream 3. c) Determine the mass fractions and mass flows of all the streams in the process. ( 27 pts) How many kilograms of wet crystals (Stream 5) are obtained per kilogram of feed (Stream 1)? (5 pts)
