An evaporator-crystallizer-filter process is used to obtain solid potassium sulfate from an aqueous solution of this salt. The feed to the process contains 32% by weight. The wet filter cake consists of solid potassium sulfate and adhering solution goes out of the crystallizer at 23*C at a ratio of 6.9 kg crystals per kg of solution. Of the water fed to the evaporator 52.1% is evaporated. The evaporator has a maximum capacity of 127 kg per minute. (a) Calculate the maximum production rate of bone-dry potassium sulfate and (b) the rate at which the feed must be fed to the evaporator to achieve this production rate.

Transcribed Image Text:An evaporator-crystallizer-filter process is used to obtain solid potassium sulfate from an aqueous solution of this
salt. The feed to the process contains 32% by weight. The wet filter cake consists of solid potassium sulfate and
adhering solution goes out of the crystallizer at 23*C at a ratio of 6.9 kg crystals per kg of solution. Of the water fed
to the evaporator 52.1% is evaporated. The evaporator has a maximum capacity of 127 kg per minute. (a) Calculate
the maximum production rate of bone-dry potassium sulfate and (b) the rate at which the feed must be fed to the
evaporator to achieve this production rate.
