Fresh feed containing 20% by weight KNO3 (K) in H2O (W) is combined with a recycle stream and fed to an evaporator. The concentrated solution leaving the evaporator, containing 50% KNO3, is fed to a crystallizer. The crystals obtained from the crystallizer are 96% KNO3 and 4% water. The supernatant liquid from the crystallizer constitutes the recycle stream and contains 0.6 kg KNO3 per 1.0 kg of H2O. Draw and label the process flowchart and perform a DFA.
