The solubility of ammonium chloride (NH4Cl)
depends on temperature as shown in the graph on the
side.
A saturated solution of ammonium chloride and
water enters a cooler/crystallizer at 70°C. At the
crystallizer:
 40% of the incoming ammonium chloride is
recovered in crystalline form
 4% of the incoming water evaporates.
 The exiting ammonium chloride – water
solution is saturated.
Determine the crystallizer’s operating temperature.
(approximately 20°C)
