Assume the following process is steady-state. 4,500 kg/h of a solution that is 1/3 K2CrO4 by mass is joined by a recycle stream containing 36.4% K2CrO4, and the combined stream is fed into an evaporator. The concentrated stream leaving the evaporator contains 49.4% K2CrOa and is in turn fed into a crystallizer in which it is cooled to form crystals of K2CrO4. The crystals are then filtered out of the solution. The "filter cake" consists of K2CrO4 crystals and a solution that contains 36.4 % K2CrOa by mass, such that the crystals account for 95% of the total mass of the filter cake. The "filtrate" solution that passes through the filter also contains 36.4% K2CrO4 and is recycled. |н-о filter cake crystallizer K2Cro4 (solid crystals) evaporator 49.4% KCro4 4500 kg'h 33.3% K2Cro4 and filter 36.4% K,Cro, solution (crystals tonstkute 95 % by mass of the fiter cake) fitrate: 36.4% K2Cro4 solution a.
