Ammonia as a Refrigerant

The calcium hydroxide produced here is reacted with the ammonium chloride separated out of the carbonating tower by filtration: Ca(OH) 2(aq) + 2NH 4 Cl (aq) → CaCl 2(aq) + 2H 2 O (l) + 2NH 3(g) The ammonia is recycled back into the process to form ammoniated brine. Calcium chloride is formed as a by-product of the Solvay Process.
