A solution containing 100 lbm KNO 3/100 lbm H 2O at 80°C is fed to a cooling crystallizer operated at 25°C. Slurry from the crystallizer (KNO3 crystals suspended in saturated solution) is fed to a filter, where the crystals are separated from the solution. Use the solubility data in Figure 6.5-1 to determine the production rate of crystals (lbm/lbm feed) and the solid-to-liquid mass ratio (lbm crystals/lbm liquid) in the slurry leaving the crystallizer.
