Question: a solution of potassium chromate k2cro4 is to be used...

Question details

A solution of potassium chromate (K2CrO4) is to be used to produce K2CrO4 crystals using an evaporator and crystallizer/filter. A 38% solution is fed to the evaporator. The stream leaving the evaporator is 48% K2CrO4 and is fed to the crystallizer/filter. Pure K2CrO4 crystals are produced and the remaining solution is 44% K2CrO4. This solution is cycled back to the evaporator. If 1.2 tons/hr of pure crystals are needed, calculate the total input to the evaporator, the feed rate to the crystallizer/filter, and the water removed from the evaporator
