Calculation of Output Acid Temperature

This section shows how Fig. 24.1 s output acid temperature is calculated. It uses (a) Fig. 24.1 s temperatures and acid compositions 

5 mass% H2SO4, 1.5 mass% H2O acid, 350 K, from cooling, dilution and recycle 

Appendix W calculates Fig. 24.1 s input and output H2SO4 and H2O masses. They are listed in Table 24.1. 

Mixing of H2S04(f) and H20(f) releases heat. This means that the enthalpy of sulfuric acid is lower than the combined enthalpies of its components.
