Question: In a process producing KNO 3 , a feed solution containing 2 0 % KNO 3 by weight is fed at a flow rate of

In a process producing KNO3, a feed solution containing 20%KNO3 by weight is fed at a flow rate of 1000 kg/h.
is fed to the evaporator. The solution was heated here at 422\deg C to obtain a solution containing 50% KNO3 by weight.
Some of the water is removed by evaporation at K. Then the concentrated solution was heated at 311 K.
It is fed to a crystallizer, where crystals containing 96% KNO3 by weight are removed.
The saturated solution containing 37.5% KNO3 taken from the crystallizer is returned to the evaporator. Back
Calculate the current coming out of the rotation and the crystal product flow in kg/h.
