An evaporator crystallizer process is used to obtain solid potassium sulfate crystals. The fresh feed to the evaporator contains 21. 60% K2SO4 and is mixed with the recycle mother liquor stream before entering the evaporator. The crystal product of the crystallizer is still wet contains 10kg K2SO4 per kg adhering mother liquor solution. The filter mother contains 40% K2S04 and is recycled to join the fresh feed. Of all the water entering the evaporator 45% is evaporated. The evaporator has a maximum capacity of 275.0 kg/h water evaporated. If the system is kept running at maximum capacity determine the ff: A. Flow rates of the feed, crystal product, recycle and mixed feed B. Composition of mixed feed
