1 4500 kg/h of KNO3 aqeuas solution at 25C are mined with a recycle stream from a filter unit, the combined stream is fed to an evaporator the concentrated solution leaving the evaporator at a temperature of 90C is a crestallizer unit which it is cooled to a temperature of 40C and then is filtared the an aqueos solution at 40C the crystals account for 95% of the total mass of the filter cake, the solubility of KNO3 are given in the following table : 25C = 40kg KNO3/100kg H20, 40C = 65kg KNO3/100kg H20, 90C = 200kg KNO3/100kg H20. 1) Calculate the unknown Flow rate of all Process stream: 2) Find the recycle ratio of mass recycle, feed rates flow. = =
