#3.An evaporation-crystallization process is used to obtain solid potassium sulfate from an aqueous solution of this salt. The feed to the process contains 18.6% weight K₂SO4. The wet filter cake consists of solid K₂SO4 crystals and 40% weight K₂SO4 solution, in a ratio 10 kg crystals/kg solution. Of the water fed to the evaporator, 82.66% is evaporated. The evaporator has a maximum capacity of 155 kg water evaporated per minute. Calculate the maximum production rate of solid K₂SO4 and the rate at which the feed must be supplied to achieve this production rate, if the wet filter cake is passed through a dryer to produce bone-dry K₂SO4.
