We now consider and justify all of the special conditions identified in Table 6.5.

6.4.1 Evaluation of Reactor R-101

Three conditions of concern have been identified for the reactor. They are high temperature, high
pressure, and non-stoichiometric feed conditions.

In order to understand why these conditions are needed, additional information about the toluene
hydrodealkylation reaction is required. Table 6.6 provides additional but limited information. This
information is divided into two groups.
Thermodynamic Information: This is information found in most chemical engineering

thermodynamic textbooks:
a. Information required to perform energy balances, including heats of reaction and phase change,
heat capacities, and so on
b. Information required to determine equilibrium conversion, including heats of formation, free
energy of formation, and so on
