An evaporation-crystallization process is used to obtain solid potassium sulfate from an aqueous solution of this salt. The fresh feed to the process contains 19.6% wt K2SO4 The wet filter cake consists of solid K2SO4 crystals and 40 % wt K2SO4 solution, in a ratio 10 kg crystals/kg solution. The filte a 40% solution is recycled to join the fresh food. Of the water fed to the evaporator, 45% is evaporated The evaporator has a maximum capacity of 175 kg/hr water evaporales Calculate a) The maximam production rate of solid K2SO4 b) The rate at which fresh feed must be supplied to achieve this production rate c) The ratio kg recycle kg fresh feed
