Hydrochloric acid is produced by absorbing gaseous HCl (hydrogen
chloride) in water. Calculate the heat that must be transferred to
or from an absorption unit if HCl(g) at 100°C and H2O(l) at 25°C
are fed to produce 1000 kg/h of 20 wt% HCl(aq) at 40°C. Assume the
heat capacity of the produced HCl is 0.557 kJ/mol HCl .°C
