Follow the steps of the Systematic Approach of Section 14.4—that is, (1) identify the system, (2) determine whether the process is batch or rate, (3) construct a schematic diagram with inputs and outputs, (4) Label known material quantities or rates of flow and so on. A solution of potassium chromate (K2CrO4) is to be used to produce K2CrO4 crystals using an evaporator and crystallizer/filter. A 38 percent solution is fed to the evaporator. The stream leaving the evaporator is 48 percent K2CrO4 and is fed to the crystallizer/ filter. Pure K2CrO4 crystals are produced and the remaining solution is 44 percent K2CrO4. This solution is cycled back to the evaporator. If 1.2 t/h 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. What will be an ideal response?
