Dealkylation reaction diagram

Here, Cj is the toluene concentration, Ch2 the hydrogen concentration, and k the reaction rate constant. The activation energy of the reaction is 220 kJ/mol. Figure 2.5 shows the reaction diagram for the dealkylation of toluene. 

The mechanical flowsheet of the reaction section of a toluene dealkylation unit in Figure 2.5 shows all instrumentation, including indicators and transmitters. The clutter on the diagram is minimized by tabulating the design and operating conditions of the major equipment below the diagram.
